Abstract

An evaluation module for evaluating a mobile device. The evaluation module includes a housing arranged to receive the mobile device to be evaluated within a cavity defined by the housing, the housing accommodating at least one sensor disposed within the cavity. The evaluation module also includes a processor and a memory. The memory stores computer-executable instructions that, when executed by the processor, cause the evaluation module to perform certain steps. In a first step, the evaluation module establishes a data connection with the mobile device for exchanging data between the mobile device and the evaluation module. Another step requires obtaining the results of one or more diagnostic tests on the mobile device, each of the one or more diagnostic tests being used to obtain information about the characteristics or performance of the mobile device's functions. A further step includes generating a report providing an evaluation of the mobile device based on the results of the one or more diagnostic tests, to be output to a user of the evaluation module.

Description

Technical Field

[0001] A module for evaluating or estimating the performance of a mobile device or wireless communication device. The module receives the mobile device within its housing or enclosure and performs diagnostic tests on the mobile device. The diagnostic tests evaluate the performance of one or more functions of the mobile device. Background Technology

[0002] The amount of waste generated each year, consisting of installed electrical or electronic equipment, is rapidly increasing. Consumers often want to upgrade their mobile devices to newer models, but this means they may want to dispose of their older, replacement devices. When consumers replace their mobile devices, they often choose to trade in their previous devices to a supplier, who can then refurbish and / or resell their old equipment. This typically allows consumers to realize some value from their old devices, but also allows the equipment to be reused or recycled in accordance with the growing preference for sustainability and waste reduction.

[0003] There is a large resale market for used or secondhand mobile devices. These devices can be purchased by suppliers from their previous owners, then refurbished and / or resold. To facilitate resale, suppliers must first assess the used mobile devices to determine the appropriate value to offer to consumers in exchange for their old devices. This value will depend on a proper demonstration of the device's various functions and its physical condition (including, for example, scratches or dents on the device's body or screen).

[0004] Typically, suppliers will use manual inspections of mobile devices to determine their value and whether the device can be reused rather than becoming e-waste. However, such manual inspections can be time-consuming and subjective.

[0005] In light of this context, there is a need for an improved system for physical and functional evaluation of mobile devices that is more objective and consistent. Summary of the Invention

[0006] The evaluation module according to claim 1 and the system according to claim 24 are described.

[0007] An evaluation module is a unit or robot used to evaluate or assess a mobile device. For example, a mobile device can be a mobile phone or a tablet computer. Evaluation may include performing various diagnostic tests, which allows for the inspection, examination, or testing of various aspects of the mobile device, including its physical condition and the correct operation of its various functions. The evaluation module communicates with the mobile device so that data (including the output of various functional tests at the mobile device) can be delivered to the evaluation module, or instructions can be exchanged between the mobile device and the evaluation module to initiate functions at the mobile device to be tested by the evaluation module.

[0008] The assessment module generates a report on the results of the performed diagnostic tests. This report can provide an overview of the mobile device's condition and functionality. In some cases, the report can provide a "rating" or "score" for the mobile device's condition. In other examples, the rating or score can be converted into an estimate of the mobile device's value, which could be its depreciated or resale value.

[0009] The assessment module allows suppliers to accurately evaluate mobile devices in order to purchase or exchange them for resale as used or refurbished equipment. The module provides a more direct, time-saving, and objective assessment of the equipment to determine its fair value for resale. In this way, the assessment module encourages the use and recycling of used mobile devices, thereby preventing them from ending up in e-waste disposal facilities.

[0010] In a first aspect, an evaluation module for evaluating a mobile device is described, the evaluation module comprising:

[0011] A housing arranged to receive the mobile device to be evaluated within a cavity defined by the housing, the housing accommodating at least one sensor arranged within the cavity;

[0012] Processor; and

[0013] The memory stores computer-executable instructions that, when executed by the processor, cause the evaluation module to:

[0014] Establish a data connection with the mobile device, the data connection being used to exchange data between the mobile device and the evaluation module;

[0015] Obtain the results of one or more diagnostic tests on the mobile device, each of the one or more diagnostic tests being used to obtain performance information regarding the characteristics or functions of the mobile device; and

[0016] Based on the results of the one or more diagnostic tests, a report providing an assessment of the mobile device is generated and output to the user of the assessment module;

[0017] The computer-executable instructions that cause the evaluation module to obtain the results of one or more diagnostic tests on the mobile device include the computer-executable instructions causing the evaluation module to perform the following operations:

[0018] Receive the results of one or more diagnostic tests from the mobile device via the data connection; and / or

[0019] The results of one or more diagnostic tests are obtained from the at least one sensor.

[0020] The housing is the shell that forms the outer wall of the evaluation module. The housing contains or surrounds a cavity in which the mobile device to be evaluated can be placed for performing certain diagnostic tests, and also houses other components of the evaluation module (such as the rotating module described below).

[0021] A processor and memory are housed within the evaluation module. The processor is a computer processor capable of executing computer-readable instructions (i.e., a computer program) retrieved from the memory. In some examples, the processor may be considered a controller.

[0022] The processor controls certain aspects of the performance of diagnostic tests used to evaluate mobile devices and compiles the results of each test. First, a data connection is established between the mobile device and the evaluation module. This data connection can be wireless, such as via Bluetooth or Wi-Fi (e.g., through a Wi-Fi hotspot generated by the evaluation module), or it can be a wired connection. The wired connection can be a physical connection, linking to the evaluation module at one end and to the mobile device at the other end via a connector (which can be attached to the mobile device by the user before it is placed inside the evaluation module's housing). The processor can then establish a data connection via the wired connection. Some operating systems on the mobile device (such as Apple iOS) may require a wired connection, while others (such as Google Android) may be able to operate wirelessly.

[0023] The processor obtains the results of one or more diagnostic tests. Obtaining the results of one or more diagnostic tests may include: in a first option, obtaining the results of a diagnostic test from a mobile device, wherein the diagnostic test is performed on the mobile device itself; or in a second option, obtaining the results may include having the evaluation module perform the diagnostic test directly on the mobile device. As an example, the results obtained according to the first option include (but are not limited to) tests of a microphone at the mobile device (for which the test is recorded at the mobile device and sent to the evaluation module), or data recorded from various sensors at the mobile device (e.g., accelerometers, gyroscopes, or light rod sensors, wherein measurements are sent to the evaluation module). As an example, the results obtained according to the second option include (but are not limited to) images of the appearance of the mobile device's outer surface from a camera at the evaluation module, or recordings of sound broadcast from a speaker at the mobile device.

[0024] The assessment module obtains or compiles results from all performed diagnostic tests and generates a report or summary of those results. It should be understood that the greater the number of diagnostic tests performed on the mobile device, the more detailed the generated report will be. More detailed reports provide a more complete and comprehensive assessment of the mobile device's condition. Advantageously, the assessment module described herein offers the option to perform more than 5, 10, 12, or even 15 different diagnostic tests on a single mobile device, each assessing a different aspect.

[0025] The evaluation module may also include a speaker arranged to emit sound waves within a housing. The computer-executable instructions that cause the evaluation module to receive the results of one or more diagnostic tests from the mobile device via the data connection may include the computer-executable instructions causing the evaluation module to: receive, via the data connection, instructions from the mobile device to emit an audio transmission from the speaker of the evaluation module, the audio transmission being recorded at one or more microphones at the mobile device; emit the audio transmission from the speaker of the evaluation module; and receive, via the data connection, the audio transmission recorded at the one or more microphones at the mobile device. The computer-executable instructions may also cause the evaluation module to: perform audio analysis on the recording of the audio transmission to obtain information about the performance of the microphones at the mobile device, to be included in a report providing an evaluation of the mobile device. In other words, diagnostic testing can test the functionality of the microphones at the mobile device by recording audio transmission from a speaker at the evaluation module at the mobile device and then sending the recording to the evaluation module via a data connection to allow the evaluation module to perform audio analysis on the recording.

[0026] The computer-executable instructions that cause the evaluation module to perform audio analysis on the recorded audio transmission may include the computer-executable instructions causing the evaluation module to: compare the spectrum of the recorded audio transmission with the spectrum of an audio transmission emitted from the speaker of the evaluation module; and determine a measure of similarity between them. Alternatively or additionally, the audio transmission may be a speech signal, and the computer-executable instructions that cause the evaluation module to perform audio analysis on the recorded audio transmission may include the computer-executable instructions that cause the evaluation module to: determine a measure of similarity between the recorded speech signal and a speech signal emitted from the speaker of the evaluation module. In either case, a specific analysis of the recorded audio is performed to evaluate the performance of the microphone at the mobile device. Due to the use of a specific predefined audio transmission from the speaker, the audio analysis can be performed by the evaluation module, and then the audio analysis can be compared with the audio recorded at the mobile device. The described audio analysis provides more information than simply whether the microphone works, but can also provide information about how well it functions, for example by considering the quality and similarity of the recording at different volumes and across frequency ranges.

[0027] One of the at least one sensors may include a microphone arranged to receive sound waves within the housing, and the computer-executable instructions that cause the evaluation module to obtain the results of one or more diagnostic tests from the at least one sensor may include the computer-executable instructions causing the evaluation module to: receive instructions from the mobile device via the data connection for initiating the recording of audio broadcasts from one or more speakers at the mobile device; and record the audio broadcasts received at the microphone of the evaluation module. The computer-executable instructions may also cause the evaluation module to: perform audio analysis of the recorded audio broadcasts to obtain information about the performance of the one or more speakers at the mobile device, to be included in a report providing an evaluation of the mobile device. The diagnostic test is used to evaluate the functionality of speakers at the mobile device by recording audio broadcasts from the mobile device. This audio analysis can be performed by the evaluation module due to the use of specific predefined audio broadcasts from speakers at the mobile device, and then compared with the audio recorded at the evaluation module. At the start of the diagnostic test, the audio broadcasts can be specified or sent by the evaluation module via the data connection to the mobile device.

[0028] The computer-executable instructions that cause the evaluation module to perform audio analysis of the recorded audio broadcast may include the computer-executable instructions causing the evaluation module to: compare the spectrum of the recorded audio broadcast with the spectrum of a specified audio broadcast emitted from one or more speakers at the mobile device; and determine a measure of similarity between them. Alternatively or additionally, the audio broadcast may be a speech signal, and the computer-executable instructions that cause the evaluation module to perform audio analysis of the recorded audio broadcast to obtain information about the performance of one or more speakers at the mobile device may include the computer-executable instructions causing the evaluation module to: determine a measure of similarity between the recorded speech signal and a speech signal emitted from one or more speakers at the mobile device. In either case, a specific analysis of the recorded audio is performed to evaluate the performance of the speaker at the mobile device. The described analysis provides more information than simply whether the speaker is working or not, and can also provide information about how well it is functioning, such as at different volumes and across a range of frequencies.

[0029] One of the at least one sensors may include a camera disposed within the housing of the evaluation module to provide images of at least one surface of the mobile device. The computer-executable instructions causing the evaluation module to obtain the results of one or more diagnostic tests from the at least one sensor at the evaluation module may include the computer-executable instructions causing the evaluation module to: obtain one or more images of at least one surface of the mobile device from the camera. The computer-executable instructions may also cause the evaluation module to: evaluate the appearance condition of the mobile device from the one or more images for inclusion in a report providing an evaluation of the mobile device. The camera may be arranged relative to the mobile device disposed in the evaluation area of ​​the evaluation module (the position where the mobile device is disposed when it is surrounded within the evaluation module for evaluation). In one example, the camera is positioned directly overhead of the evaluation area. Optionally, more than one camera may be disposed within the housing of the evaluation module to allow images of the mobile device to be obtained from different directions. Based on the images obtained by the one or more cameras, the evaluation module is able to identify the presence and location of scratches, dents, or other defects on any surface or edge of the mobile device.

[0030] Obtaining one or more images of at least one surface of the mobile device by the evaluation module may include acquiring multiple images during rotation of the mobile device within the housing, each of the multiple images being acquired at a different stage of the rotation. In other words, the evaluation module may use a rotation mechanism, as described below and housed within the housing of the evaluation module, to rotate or flip the mobile device while inside the evaluation module. One or more cameras may each capture images during rotation. This means that at some point during rotation, each edge or surface of the mobile device is positioned opposite at least one camera such that it is imaged. Rotation allows different surfaces of the mobile device to be imaged from different directions and perspectives, and thus provides the possibility of improved identification of any defects.

[0031] The computer-executable instructions that cause the evaluation module to obtain the results of one or more diagnostic tests from at least one sensor at the evaluation module may include the computer-executable instructions causing the evaluation module to: receive instructions from the mobile device via the data connection to initiate the acquisition of one or more images on the screen during a period when the display of the mobile device is illuminated; and acquire one or more images of the display of the mobile device at a camera disposed within the housing during the period when the screen is illuminated. The computer-executable instructions may also cause the evaluation module to perform analysis of the images of the screen to obtain information about the performance of the display at the mobile device, the information being included in a report providing an evaluation of the mobile device. The diagnostic test examines all areas of the display of the mobile device to see if they operate or are illuminated as expected. The test can identify dark spots or dead pixels on the display of the mobile device. In some cases, the screen at the mobile device may be illuminated with more than one color (e.g., a color wheel), and analysis of the images of the screen acquired by the camera at the evaluation module can confirm the correct color representation at the display of the mobile device. In some cases, the illumination at the screen of the mobile device may change over time (e.g., through different color cycles), wherein continuous images are acquired intermittently by the camera at the evaluation module during the changing illumination of the screen. Then, the continuous images can be analyzed to confirm the correct color representation on the display screen.

[0032] The housing may also include one or more graphic objects arranged within the housing to be visible to at least one camera at the mobile device within a cavity defined by the housing. The computer-executable instructions may also cause the evaluation module to: receive, via the data connection, at least one image of the one or more graphic objects acquired at the mobile device by the at least one camera; and perform analysis of the at least one image of the one or more graphic objects to obtain information about the performance of the at least one camera at the mobile device, to be included in a report providing an evaluation of the mobile device. This diagnostic test examines one or more cameras of the mobile device by obtaining images of specific objects, allowing the obtained images to be compared with known graphic objects. This diagnostic test allows for consistent analysis of the quality of images produced by the mobile device's cameras. The graphic object can be any image or graphic representation that allows testing of the camera. The graphic object may be mounted on the inner wall of the housing of the evaluation module (e.g., as a sticker). Each camera at the mobile device can be tested in the same manner in different diagnostic tests. In some cases (e.g., if the mobile device has a front-facing camera and a rear-facing camera), the diagnostic test can be repeated after the mobile device is rotated in the evaluation module by the rotation mechanism described below (the rotation positions the different cameras on the mobile device relative to the graphic object mounted inside the evaluation module).

[0033] One of the one or more graphic objects may be a QR code, and the computer-executable instructions causing the evaluation module to perform analysis of at least one image of the one or more graphic objects may include the computer-executable instructions further causing the evaluation module to analyze the performance of the autofocus function of the at least one camera at the mobile device. Alternatively or additionally, one of the one or more graphic objects is a graphic object comprising at least three colors. The computer-executable instructions causing the evaluation module to perform analysis of at least one image of the one or more graphic objects may include the computer-executable instructions further causing the evaluation module to analyze the color accuracy of the at least three colors in the at least one image of the one or more graphic objects. The different types of graphic objects test different aspects of the camera of the mobile device and the quality of the images obtained by the camera. In some cases, using different types of graphic objects may allow testing of the autofocus function of the camera at the mobile device.

[0034] The evaluation module is configured to receive the results of one or more diagnostic tests performed at the mobile device. This may include the evaluation module being configured to: receive an indication of the presence or absence of a physical or embedded SIM within the mobile device, and optionally receive a test of the ability of the identified physical or embedded SIM to connect to a telecommunications network; and / or receive a geographic location signal from a global navigation satellite (GNSS) transmitter, wherein the processor is further configured to compare the location identified by the geographic location signal with a predetermined geographic location of the evaluation module to obtain information about the performance of the GNSS receiver at the mobile device.

[0035] The evaluation module is configured to obtain the results of one or more diagnostic tests on the mobile device. This may include the evaluation module being configured to: establish Bluetooth communication between the evaluation module and the mobile device to determine the functionality of Bluetooth capabilities at the mobile device; and / or establish WiFi communication between the evaluation module and the mobile device to determine the functionality of WiFi capabilities at the mobile device; and / or receive an assessment of the health status of the mobile device's battery from the mobile device; and / or receive identification of the presence of any non-original components within the mobile device from the mobile device.

[0036] The evaluation module may further include a microphone arranged within the housing to receive sound waves. The evaluation module is configured to obtain the results of one or more diagnostic tests performed by the evaluation module on the mobile device from at least one sensor at the evaluation module, the at least one sensor being the microphone. The evaluation module may be configured to: receive instructions from the mobile device via the data connection to initiate recording at the microphone during a subsequent activation period of the vibration motor at the mobile device; and record sound waves received at the microphone of the evaluation module during the activation period of the vibration motor at the mobile device. The processor may also be configured to determine the presence or absence of sound from the vibration motor in the recording of sound waves received at the microphone of the evaluation module to obtain information about the performance of the vibration motor at the mobile device. The diagnostic test checks that the vibration motor (used by the user to issue notifications or alarms to the user of the mobile device) is correctly activated and functioning.

[0037] The evaluation module may also include one or more cameras disposed within the housing. The evaluation module is configured to obtain results of one or more diagnostic tests performed by the evaluation module on the mobile device from at least one sensor at the evaluation module, the at least one sensor being one or more cameras. The evaluation module may be configured to: receive instructions from the mobile device via the data connection to initiate the acquisition of one or more images from the one or more cameras during illumination by the camera flash at the mobile device; and acquire one or more images from the one or more cameras during illumination by the camera flash at the mobile device. The evaluation module may also be configured to: determine the presence or absence of light from the camera flash at the mobile device in the acquired one or more images to obtain information about the performance of the camera flash at the mobile device. The diagnostic test checks that the mobile device correctly illuminates the camera flash and examines the expected light intensity.

[0038] The evaluation module is configured to obtain the results of one or more diagnostic tests on the mobile device. This may include the evaluation module being configured to: receive measurements of light levels at a light sensor on the mobile device; and / or receive measurements of orientation and / or angular velocity from a gyroscope on the mobile device; and / or receive measurements of the mobile device's orientation from a compass on the mobile device; and / or receive measurements of the mobile device's acceleration from an accelerometer on the mobile device; and / or receive measurements of air pressure from a barometer on the mobile device; and / or receive measurements of one or more touch interactions received at different areas of the touchscreen mobile device in response to a command issued to the user of the mobile device to provide touch input at different areas of the touchscreen. These diagnostic tests examine the outputs or measurements from various sensors on the mobile device. In many cases, the user provides input to test the sensors, for example, by following instructions on the screen of the mobile device. Thus, these tests can be applied before or after the mobile device is placed inside the housing of the evaluation module. Ideally, the measurements from the sensors are compared to known or expected values, such as a range of "average" or "typical" values ​​for a given parameter under normal use and when the sensor is functioning correctly.

[0039] The evaluation module may also include a mechanism for rotating the mobile device within the housing. This rotation mechanism allows the mobile device to be rotated or flipped within the evaluation module's housing. This allows cameras arranged within the evaluation module to acquire images of different surfaces of the mobile device and images from different angles as the mobile device rotates. It also allows for the performance of other diagnostic tests, such as testing the front-facing camera on the mobile device before rotation and testing the rear-facing camera on the mobile device after rotation.

[0040] The rotation mechanism may include: a base portion; a flat support plate for supporting the mobile device received in the housing, wherein, in a first position, the mobile device is arranged to have a first flat surface opposite to a flat surface of the flat support plate and a second flat surface opposite to the first flat surface, the second flat surface facing outwards toward a cavity defined by the housing; and a concave support plate arranged at a fixed angle to the upper surface of the base portion, the concave support plate for receiving the mobile device during rotation. Inclination of the flat support plate relative to the concave support plate allows the mobile device to pivot about one edge of the mobile device to tilt the mobile device toward the concave support plate, wherein the concave support plate is configured to receive the mobile device such that, in a second position, the first flat surface of the mobile device faces outwards toward the cavity defined by the housing. Thus, the mobile device rotates in a controlled manner, during which the mobile device is adequately supported to avoid any damage to the mobile device during rotation.

[0041] The second flat surface of the mobile device may terminate at a second peripheral edge, and the concave support plate may be configured to receive the mobile device such that the concave support plate contacts the mobile device at a portion of the second peripheral edge. This concave plate allows devices with different shapes and different outer contours (including foldable mobile devices) to be adequately supported.

[0042] The concave support plate can be arranged to move relative to the flat support plate to change the spacing between them, and wherein, after the concave support plate receives the mobile device, increasing the spacing between the concave support plate and the flat support plate causes the mobile device to further pivot about one edge of the mobile device until the mobile device is arranged in a third position to have at least a portion of a second flat surface opposite to the upper surface of the base portion.

[0043] In some cases, the mobile device in the second position has rotated more than 90 degrees around one edge of the mobile device compared to the first position. In some cases, the mobile device in the third position has rotated 180 degrees around one edge of the mobile device compared to the first position.

[0044] In a second aspect, there exists a system comprising: the aforementioned evaluation module; and a mobile device for evaluation, wherein the mobile device is arranged to communicate with the evaluation module. In some cases, the mobile device is arranged within the housing of the evaluation module.

[0045] The mobile device may include a processor and memory storing computer-executable instructions that, when executed by the processor, cause the mobile device to: perform one or more diagnostic tests, each of which is used to obtain information about the performance of the characteristics or functions of the mobile device; and / or communicate the results of the one or more diagnostic tests on the mobile device to the evaluation module, each of which is used to obtain information about the performance of the characteristics or functions of the mobile device. The computer-executable instructions, when executed by the processor, may also cause the mobile device to: initiate one or more functions at the mobile device, the performance of which is monitored by the evaluation module. In some cases, communication from the mobile device to the evaluation module may be performed via software application-based or web browser-based evaluation at the mobile device. In some cases, a user may need to provide input to the mobile device to perform certain diagnostic tests.

[0046] In a third aspect, there is a method for evaluating mobile devices, the method comprising:

[0047] Establish a data connection for data exchange between the mobile device to be evaluated and the evaluation module;

[0048] Obtain the results of one or more diagnostic tests on the mobile device, each of the one or more diagnostic tests being used to obtain information about the characteristics of the mobile device or the performance of the functions of the mobile device;

[0049] Based on the results of the one or more diagnostic tests, a report providing an assessment of the mobile device is generated and output to the user of the assessment module;

[0050] The results of one or more diagnostic tests obtained on the mobile device include:

[0051] Receive the results of one or more diagnostic tests from the mobile device via the data connection; and / or

[0052] The results of one or more diagnostic tests are obtained from at least one sensor located at the evaluation module.

[0053] It should be understood that the above discussion of the various characteristics of the evaluation module and system also applies to the common characteristics of this method.

[0054] The method can be performed across both the mobile device and the evaluation module. The software application can be downloaded to the mobile device before the evaluation begins and can be used to interact with the evaluation module and initiate certain diagnostic tests. In some cases, the software application on the mobile device can send an instruction to the evaluation module that it is initiating a specific diagnostic test, and the evaluation module should measure the results. The software application on the mobile device can simply provide the evaluation module with the results of diagnostic tests that occur only on the mobile device.

[0055] Some diagnostic tests may require user input (e.g., user interaction with a touchscreen on a mobile device to test the touch sensors in the touchscreen), and the software application will guide the user through such tests by issuing instructions for user input via the mobile device's display. Tests requiring user input will be performed before or after the mobile device is placed in the evaluation module, but a data connection will need to be established between the evaluation module and the mobile device to exchange information or results from one or more diagnostic tests.

[0056] An alternative solution could be to use a web browser-based assessment instead of the software application. Again, a web browser-based assessment can guide the user through certain instructions that require their input.

[0057] Receiving the results of one or more diagnostic tests from the mobile device via the data connection may include: receiving, via the data connection, an instruction from the mobile device to transmit an audio transmission from the speaker of the evaluation module, the audio transmission being recorded at one or more microphones on the mobile device; transmitting the audio transmission from the speaker of the evaluation module; and receiving, via the data connection, the audio transmission recorded at the one or more microphones on the mobile device. The method may further include performing audio analysis on the recording of the audio transmission to obtain information about the performance of the microphones on the mobile device, to be included in a report providing an evaluation of the mobile device. For example, the mobile device (e.g., via a software application on the device) may issue an instruction to transmit, and then the recording of the audio transmission may be returned to the evaluation device after the recording of the audio transmission has already been recorded at the mobile device.

[0058] Performing audio analysis on the recorded audio transmissions may include comparing the spectrum of the recorded audio transmissions with the spectrum of audio transmissions emitted from the speakers of the evaluation module; and determining a measure of the similarity between them. These steps will be performed at the evaluation module.

[0059] Audio broadcasts can be speech signals, and performing audio analysis on the recording of the audio transmission can include determining a measure of similarity between the recorded speech signal and a speech signal emitted from the speaker of the evaluation module. These steps will be performed at the evaluation module.

[0060] One of the at least one sensors may include a microphone arranged to receive sound waves within the housing. Obtaining the results of one or more diagnostic tests from the at least one sensor may then include: receiving, via a data connection, a command from the mobile device to initiate recording of audio broadcasts from one or more speakers located at the mobile device; and recording the audio broadcasts received at the microphone of the evaluation module. The method may further include performing audio analysis on the recorded audio broadcasts to obtain information about the performance of the one or more speakers located at the mobile device, to be included in a report providing an evaluation of the mobile device. For example, the mobile device (e.g., via a software application) may send a command to initiate recording, and then the mobile device may transmit the audio broadcasts to be recorded by the evaluation module.

[0061] Performing audio analysis on the recorded audio broadcast may include comparing the spectrum of the recorded audio broadcast with the spectrum of a specified audio broadcast emitted from one or more speakers at a mobile device; and determining a measure of the similarity between them. This step will be performed in the evaluation module.

[0062] Audio broadcasts can be speech signals, and performing audio analysis on recorded audio broadcasts can include determining a measure of similarity between the recorded speech signal and speech signals emitted from one or more speakers of a mobile device. This step will be performed at the evaluation module.

[0063] One of the at least one sensors may include a camera disposed within the housing to provide images of the surface of the mobile device. Then, enabling the evaluation module to obtain the results of one or more diagnostic tests from the at least one sensor at the evaluation module may include obtaining one or more images of at least one surface of the mobile device from the camera. The method may further include evaluating the appearance condition of the mobile device from the one or more images for inclusion in a report providing an evaluation of the mobile device. All these steps are performed by the evaluation module on the mobile device.

[0064] The method further includes rotating the mobile device within the evaluation module to acquire multiple images during the rotation of the mobile device within the housing, each of the multiple images being acquired at a different stage of the rotation. The evaluation module may use a rotation mechanism housed within the housing of the evaluation module to rotate the device.

[0065] Obtaining the results of one or more diagnostic tests from at least one sensor at the evaluation module may include: receiving, via the data connection, a command from the mobile device to initiate the acquisition of one or more images on the screen during a period when the screen of the mobile device is illuminated; and acquiring one or more images of the screen of the mobile device at a camera disposed within the housing during the period when the screen is illuminated. The method may further include performing analysis of the images of the screen to obtain information about the performance of the display at the mobile device, to be included in a report providing an evaluation of the mobile device. The mobile device may initiate the command and then illuminate the screen at the mobile device so that the images are acquired by the one or more cameras at the evaluation module.

[0066] One or more graphic objects may be arranged inside a housing to be visible to at least one camera at a mobile device within a cavity defined by the housing. The method may further include: receiving from the mobile device via the data connection at least one image of the one or more graphic objects acquired by the at least one camera at the mobile device; and performing analysis on the at least one image of the one or more graphic objects to obtain information about the performance of the at least one camera at the mobile device, to be included in a report providing an evaluation of the mobile device. The mobile device may acquire the at least one image and then send the at least one image to the evaluation module. Analysis of the at least one image may be performed at the evaluation module.

[0175] It should be noted that the accompanying drawings are for simplicity and are not necessarily drawn to scale. The same features have the same reference numerals. Detailed Implementation

[0176] refer to Figure 1 ,exist Figure 1 (a) shows an evaluation module 10 having a mobile device 12 to be evaluated, which is arranged within a cavity 14 defined by a housing 16 or casing of the evaluation module. Figure 1 The mobile device 12 to be evaluated is shown in more detail in (b). The mobile device 12 can be any wireless communication device, such as a mobile phone or a tablet computer. The evaluation module 10 is configured to evaluate or estimate various physical and functional characteristics of the mobile device 12 in order to generate a report summarizing it.

[0177] Evaluation module 10 and mobile device 12 are communicatively coupled via data connection 18 to allow data exchange. Data connection 18 can be wired or wireless. A wired connection can be provided by the user inserting the connector of the wire into the mobile device 12 under test before placing it inside housing 16. In this case, the other end of the wire is communicatively coupled to evaluation module 10. A wireless connection can be established by connecting the mobile device 12 to, for example, a WiFi hotspot generated by evaluation module 10.

[0178] The evaluation module includes a processor 20 and a memory 22, the memory 22 storing computer-executable instructions that, when executed by the processor 20, cause the evaluation module 10 to function in a certain way. The evaluation module 10 may also include a controller (not shown) configured to send instructions to the processor 20 for executing the instructions.

[0179] Evaluation module 10 includes a housing 16 or enclosure that defines an internal cavity 14. A mobile device 12 for evaluation can be placed by a user in an evaluation area 24 within the housing. Evaluation area 24 is a location within housing 16 that provides proper alignment of the mobile device 12 with various sensors at the evaluation module for diagnostic testing. Placing the mobile device 12 in the evaluation area 24 within the housing also ensures successful rotation of the mobile device 12 via a rotation mechanism within the evaluation module, as discussed further below.

[0180] As described above, housing 16 accommodates multiple sensors that can be used in diagnostic tests. The number and type of sensors can depend on the specific diagnostic test to be performed at a given evaluation module.

[0181] Specifically, one type of sensor within the housing may be one or more cameras 26 mounted within the cavity 14. The one or more cameras 26 may be arranged or oriented to capture images of the mobile device 12 within the evaluation area 24. As an example, suitable cameras 26 are located in... Figure 5 of (b) Figure 6 , Figure 8 of (b) Figure 9 (b) and Figure 10 As shown in (b), however, more than one camera may be mounted at different locations within the cavity 14 of the housing 16 to image the mobile device 12 from various angles or directions. The use of one or more cameras 26 is further described below with respect to the performance of diagnostic tests.

[0182] Additional sensors housed within the enclosure include a microphone 28 arranged to receive sound waves within the enclosure 16, and a Global Navigation Satellite System (GNSS) signal receiver 30 for receiving GNSS signals. The use of these sensors is further described below with respect to the performance of diagnostic tests.

[0183] The evaluation module 10 may also include one or more peripheral devices, which are hardware components controlled by the processor 20, or may include other non-computational elements for performing diagnostic tests. Figure 1 In (a), a first peripheral device is shown, which is a speaker 32 connected to the processor, and the speaker 32 can be arranged to emit sound waves within the housing. A second peripheral device is an illumination device 34 (e.g., an LED array) mounted within the cavity 14 of the housing 16 to allow illumination of the cavity and any mobile device 12 therein. Additional peripheral devices are one or more graphic objects 36 mounted on the inner surface of the wall of the housing 16. The one or more graphic objects 36 can be arranged within the field of view of a camera of the mobile device 12 located in the evaluation area 24 of the housing 16. The use of each peripheral device is described below in relation to the execution of diagnostic tests.

[0184] The evaluation module may also include one or more antennas 38 for enabling various data connection modes to the mobile device 12, including WiFi and Bluetooth transceivers.

[0185] Figure 1 (b) shows mobile device 12, an example of a mobile device (or wireless communication device) to be evaluated within the evaluation module. For example, the mobile device could be a mobile phone or a tablet computer. The mobile device is communicatively coupled to the evaluation module via data connection 18.

[0186] Although the mobile device 12 itself is not part of the evaluation module 10, it is provided for completeness. Figure 1 (b) Specifically, it illustrates a mobile device 12 having a processor 42 and a memory 44, whereby the memory 44 stores computer-executable instructions that, when executed by the processor 42, cause the mobile device 12 to function in a certain way. Specifically, the processor 42 may be connected to multiple sensors located on the mobile device 12. These sensors include a touchscreen 46, a compass 48, a camera 50, a light level detector 52, an accelerometer 54, a gyroscope 56, a GNSS receiver 58, and a microphone 66. The processor 42 may also be connected to other components, such as a vibration motor 60 of the mobile device 12, a speaker 68, a display screen 69, and a lighting device 62 (or a camera flash), as well as other sensors or components 64.

[0187] In some cases, a dedicated software application runs on the mobile device 12. Communication from the mobile device 12 to the evaluation module 10 is conducted through the application. The application can be used to establish an initial data connection 18 from the mobile device 12 to the evaluation module 10, and can also initiate certain diagnostic tests (including measurements at various sensors or activation of other components) as needed to complete the diagnostic tests. The owner or user of the mobile device will download and install the software application (e.g., from the Apple App Store or Google Play, depending on their mobile device's operating system) before starting the evaluation of the mobile device 12 and typically before connecting it to the evaluation module 10.

[0188] In other cases, users can access diagnostic routines via a web browser on their mobile device 12. In much the same manner as software applications, web browser-based diagnostic routines can be used to establish an initial data connection 18 from the mobile device 12 to the evaluation module 10, and can also initiate certain diagnostic tests (including measurements at various sensors or activation of other components) as needed to complete the diagnostic tests.

[0189] In some cases, software application-based or web browser-based diagnostic routines guide the user or owner of mobile device 12 through the evaluation process. Specifically, these routines may establish or initiate a data connection 18 between mobile device 12 and evaluation module 10, and then display instructions to the user on the mobile device's screen, for example, instructing the user to interact with the mobile device in some way. These instructions may request the user to perform certain actions (e.g., reorienting the mobile device, or touching certain areas of the screen or fingerprint sensor). In this way, mobile device 12 can collect the results of various diagnostic tests on certain functions of the device, which can then be sent to or received by evaluation module 10. Software application-based or web browser-based diagnostic routines may further instruct the user to place mobile device 12 in the evaluation area 24 of evaluation module 10 at an appropriate time, allowing evaluation module 10 to perform diagnostic tests on mobile device 12 independently of the user. Once the mobile device 12 has been placed inside the evaluation module 10, the software application running on the processor 42 of the mobile device 12 can also be responsible for interacting with the evaluation module 10 to initiate certain diagnostic tests, such as by sending instructions or commands to continue certain steps of different diagnostic tests in the diagnostic test.

[0190] In use, the evaluation module 10 first establishes a data connection 18 with the mobile device 12. This allows data exchange between the evaluation module 10 and the mobile device 12. The data may include instructions sent from the mobile device 12 to the evaluation module 10 and vice versa, to perform diagnostic tests. The data may also include the results of the diagnostic tests (e.g., measurements from sensors at the mobile device 12 that are sent to the evaluation module 10).

[0191] Next, the evaluation module 10 obtains the results of one or more diagnostic tests on the mobile device 12. The results can be obtained in two ways. A first option is to receive results from the mobile device 12 via data connection 18, where the results of one or more diagnostic tests are measurements from sensors at the mobile device 12, or information retrieved from the mobile device 12. A second option is to obtain results measured at at least one sensor at the evaluation module 10. Further discussion of specific diagnostic tests is provided below.

[0192] After the evaluation module 10 has collected or organized the results of one or more diagnostic tests, the evaluation module 10 generates a report providing an evaluation of the mobile device 12 based on the results of the one or more diagnostic tests. This report is output to the user of the evaluation module 10. The report output by the evaluation module 12 can be sent to the evaluation module 10 and / or the display screen of the mobile device 12. Figure 1 (Not shown in the image). Alternatively, the report can be sent to a printer or stored in non-volatile memory that communicates with the processor 20 of the evaluation module 10, or stored in "cloud-based" storage 66.

[0193] The report provides an assessment of the mobile device 12 based on the results of the one or more diagnostic tests. The report may include a compilation of the results of each diagnostic test. The report may summarize the results of each diagnostic test, or it may provide results of further analysis of these results. For example, in some cases, the assessment module 10 is able to derive further information from the results of each diagnostic test. In some cases, the results will provide a rating of the condition of the mobile device 12. The rating may apply machine learning or artificial intelligence (AI) techniques to improve the accuracy of any such rating. In some cases, the report may provide a suggested market value or transaction value for the mobile device 12 based on the rating. In any case, the output of the assessment module 10 is a report providing the user with information about the performance and condition of the mobile device 12.

[0194] Figure 2 , Figure 3 , Figure 4 and Figure 5Different views of the outer surface of the evaluation module 10 are shown. As described above, the evaluation module includes a housing 16 or a rigid shell, which defines and surrounds an internal cavity 14. The mobile device 12 can be placed within the cavity 14 (specifically, at the evaluation area 24) to allow evaluation of the mobile device 12. In particular, one or more diagnostic tests can be performed on the mobile device 12 within the housing 16. It should be understood that when the mobile device 12 is outside the housing, other diagnostic tests can be performed on the mobile device 12, the results of which are obtained by the evaluation module 10, as described below.

[0195] Figure 5 A view of the evaluation module 10 with an opening or an open door leading to the housing 16 is shown. Figure 5 (a) shows a three-dimensional view. Figure 5 (b) shows a cross-sectional view. An opening to the housing is provided by a sliding tray 70, which moves in and out of the cavity 14. When the tray 70 is fully inserted into the cavity 14, the upright section 72 of the sliding tray provides part of the wall of the housing 16. Figure 5 In a specific example, the upright section 72 of the sliding tray 70 also includes a display 74 on the housing 16, which can be used to display a report generated by the evaluation module 10 after the results of one or more diagnostic tests are obtained. However, those skilled in the art will understand that this is not the only placement of the display 74 on the outer wall of the evaluation module. The display 74 may include a touchscreen for user interaction with the evaluation module 10, including access inputs and commands.

[0196] The evaluation area 24 is arranged on the upper surface of the sliding tray 70, which is the location where the mobile device 12 in the evaluation module 10 is properly aligned to perform various diagnostic tests. To insert the mobile device 12 to be tested or evaluated into the evaluation module 10, the user pulls or slides the sliding tray 70 out of the rest of the housing 16. The mobile device 12 can then be placed in the evaluation area 24 to be arranged on the upper surface of the sliding tray 70. In this way, the mobile device 12 is supported by a platform at the base of the sliding tray 70. The sliding tray 70 is then pushed into or slid into the housing 16 until the upright section 72 of the sliding tray 70 engages with the rest of the wall of the housing 16. The housing 16 is then closed such that the internal cavity 14 (and the mobile device 12 for evaluation) is surrounded by the walls of the housing 16.

[0197] The other walls of housing 16 (though not shown in the figure) are equipped with input and output interfaces for connecting power, Ethernet cables, and USB connectors.

[0198] Execution of diagnostic tests

[0199] One or more diagnostic tests can be performed on the mobile device 12 to be evaluated. The results of those diagnostic tests are obtained through the evaluation module 10. Diagnostic tests are performed through interaction between the mobile device 12 and the evaluation module 10, or by testing the mobile device 12 through the evaluation module. In order to perform diagnostic tests through interaction between the mobile device 12 and the evaluation module 10, in some examples, a software application can be downloaded, installed, and run on the mobile device 12. The software application can initiate tests or measurements of specific functions at the mobile device and then send the results of these tests to the evaluation module 10. Alternatively, a web browser-based diagnostic routine can be accessed by a user of the mobile device 12, which similarly initiates tests or measurements of specific functions at the mobile device 12 and then sends the results of these tests to the evaluation module 10. In other cases, the data exchange between the mobile device 12 and the evaluation module 10 does not depend on the software application or the web browser-based diagnostic routine.

[0200] A wide variety of diagnostic tests can be performed on the mobile device 12, with results obtained by the evaluation module 10. Different numbers and combinations of diagnostic tests can be performed in different implementations of the evaluation module 10. The tests, as well as their order and flow, can be adapted by the users of the evaluation module 10 to meet their own business needs. Various possible tests are discussed below; however, it should be understood that other tests can be performed by the evaluation module 10, and not all tests described will always be performed on any given mobile device 12.

[0201] Benefits are gained by performing a different set of diagnostic tests on a given mobile device 12. In particular, obtaining results from a greater number of diagnostic tests provides a more complete and reliable assessment of the overall condition of the mobile device 12. In some cases, three or more, five or more, eight or more, ten or more, or all of the different diagnostic tests may be performed on the given mobile device 12 being evaluated.

[0202] • Test the microphone at the mobile device

[0203] Diagnostic tests can be performed to obtain information about the performance of microphone 66 at mobile device 12 (checking all microphones and recording quality). As described above, speaker 32 is mounted within cavity 14 defined by housing 16 of evaluation module 10. Speaker 32 is arranged to emit sound waves within housing 16.

[0204] To perform diagnostic tests, evaluation module 10 receives instructions from mobile device 12 to transmit audio via speaker 32 mounted within housing 16 of evaluation module 10. These instructions may originate from a software application on mobile device 12 that initiates the specific diagnostic test.

[0205] The evaluation module 10 then transmits audio via speaker 32. The audio transmission may be, for example, a predefined, pre-recorded audio file stored in and retrieved from the memory 22 of the evaluation module. The audio transmission may include a range of audio frequencies and amplitudes (volume) and may include speech or non-speech audio.

[0206] Audio transmissions can be received and recorded at the mobile device 12, especially after they have been received via the microphone 66 of the mobile device 12. In some cases, the recording of audio transmissions can be controlled by a software application at the mobile device 12. The recorded audio transmissions are then sent to the evaluation module 10 via the established data connection 18.

[0207] Once a recording of the audio transmission is received at the evaluation module 10, the evaluation module 10 can perform audio analysis on the recording. The audio analysis provides an indication of the performance or functionality of the microphone 66 at the mobile device 12. The audio analysis aims to evaluate the ability of the microphone 66 to sense or receive audio signals at different frequencies and volumes.

[0208] In a first example of audio analysis performed by evaluation module 10, evaluation module 10 compares the spectrum of a known predefined audio transmission emitted at speaker 32 of evaluation module 10 with the spectrum of an audio transmission recorded at mobile device 12. For example, this comparison uses frequency component analysis via Fourier transform to compare the spectrum of the recorded audio transmission with the spectrum of the original audio transmission emitted by evaluation module 10. A measure of similarity between the two spectra (e.g., the degree of deviation in the recorded audio transmission from the original broadcast audio transmission) can then be determined. The higher the level of similarity, the better the performance of microphone 66 (and the connected audio circuitry) at mobile device 12 is considered.

[0209] In the second example of the audio analysis performed by the evaluation module 10, the audio transmission emitted at the speaker 32 of the evaluation module 10 is a speech audio file (in other words, a recording of spoken speech). Here, a measure of similarity can be determined between the speech audio transmission emitted from the speaker 32 at the evaluation module 10 and the speech audio transmission recorded at the mobile device. Specifically, the speech audio file emitted by the speaker 32 of the evaluation module and recorded by the mobile device via the microphone 66 is evaluated by a built-in neural network trained to recognize the original signal. As previously stated, the higher the similarity, the better the performance of the microphone 66 at the mobile device 12.

[0210] It should be understood that the diagnostic test will be performed on the mobile device 12, which is surrounded inside the evaluation module 10, because it allows the test to be performed under ideal conditions (i.e., minimizing external noise interference).

[0211] • Test the speaker at the mobile device

[0212] Diagnostic tests can be performed to obtain information about the performance of the speaker 68 at the mobile device 12 (a function to check all speakers and sound quality). As described above, the microphone 28 is mounted within a cavity 14 defined by the housing 16 of the evaluation module 10. The microphone 28 is arranged to receive sound waves emitted within the housing 16.

[0213] To perform diagnostic tests, evaluation module 10 receives a command from mobile device 12 to begin recording audio broadcasts received at microphone 28 of evaluation module 10. In some cases, the command may originate from a software application on mobile device 12 that initiates the specific diagnostic test via established data connection 18.

[0214] Mobile device 12 transmits audio broadcasts from speaker 68 at mobile device 12. The audio broadcasts are predefined and pre-recorded audio files, which may have been retrieved by mobile device 12 from memory 44 received from evaluation module 10 via data connection 18, in communication with the mobile device's processor. The predefined and pre-recorded audio files include audio in a frequency and volume range.

[0215] Evaluation module 10 records the audio broadcast received via microphone 28. Evaluation module 10 then performs audio analysis on the recorded audio broadcast. The audio analysis provides an indication of the performance or function of speaker 68 at mobile device 12, particularly its ability to accurately broadcast audio frequencies and volume ranges.

[0216] In a first example of audio analysis performed by evaluation module 10, evaluation module 10 compares the known spectrum of an audio broadcast emitted from speaker 68 of mobile device 12 with the spectrum of an audio broadcast recorded at evaluation module 10. A measure of similarity between the two spectra can then be determined (e.g., the degree of deviation between the audio broadcast from mobile device 12 and the audio broadcast recorded at evaluation module 10). The higher the similarity, the better the performance of speaker 68 at mobile device 12.

[0217] In a second example of the audio analysis performed by the evaluation module 10, the audio broadcast emitted from the speaker 68 of the mobile device 12 is a speech audio file (in other words, a recording of spoken speech). Here, a measure of similarity can be determined between the original speech audio broadcast emitted from the speaker 68 of the mobile device and the speech audio broadcast recorded via the microphone 28 of the evaluation module. Again, this similarity can be evaluated by a neural network trained to recognize the original signal. As previously stated, the higher the level of similarity, the better the performance of the speaker 68 at the mobile device 12.

[0218] It should be understood that the diagnostic test will be performed on the mobile device 12 enclosed in the housing 16 of the evaluation module 10, as this allows the test to be performed under ideal conditions (i.e., minimizing external noise interference).

[0219] • Assess the appearance of the mobile device.

[0220] The physical condition of the mobile device 12 can be assessed. For example, the surfaces of the casing and screen of the mobile device 12 being assessed can be inspected and evaluated to identify any scratches, dents, or defects.

[0221] To perform the diagnostic test, at least one camera 26 is mounted within a cavity 14 defined by the housing 16 of the evaluation module 10. The at least one camera 26 is arranged to point at the mobile device 12 from the evaluation area 24 of the housing 16. Ideally, multiple cameras are used to obtain more than one image of the mobile device 12 from multiple directions. In this way, different surfaces of the mobile device 12 can be imaged at different angles or the same surface.

[0222] In a particular example, multiple cameras may be mounted within the housing to obtain images of the mobile device 12 from, for example, six separate angles (front, rear, left, right, bottom, and top). As discussed further below, when housed within the housing 16, the mobile device 12 can be rotated via a rotation mechanism, and the rotation of the mobile device 12 relative to the fixed positions of one or more cameras 26 allows various different aspects and surfaces of the mobile device 12 to be imaged during the rotation cycle.

[0223] At least one camera 26 at the evaluation module 10 is used to acquire one or more images of the surface of the mobile device 12 opposite to the camera. The evaluation module can then evaluate the appearance condition of the mobile device 12 based on the one or more images. In particular, any scratches, dents or other defects on the surface of the mobile device 12 can be identified, and the extent of any damage can be detected.

[0224] In some cases, a specially trained neural network is used to analyze the one or more images acquired by the camera 26 in the evaluation module. Specifically, the neural network can a) determine an appearance index (grade) of the mobile device 12 based on any identified damage, scratches, dirt, or dents on the body and screen; and / or b) detect and highlight areas of such damage on the surface of the mobile device 12 in the original image presented to the user.

[0225] Any identified defects can then be listed in the report generated by the evaluation module 10. In some cases, images, along with indications or highlights of the location of any damage or effect, can be included in the report. In some cases, the number and severity of defects can be determined by the evaluation module 10 to grade the appearance condition of the mobile device 12, and that grade can then be included in the report.

[0226] • Test the display screen at the mobile device

[0227] Diagnostic tests can be performed to obtain information about the performance of the display 69 at the mobile device 12. In other words, diagnostic tests can be performed to identify whether the display 69 is working correctly across all areas and zones of the display (including checking for liquid crystal display (LCD) defects, brightness levels, and screen aging).

[0228] To perform diagnostic testing, evaluation module 10 receives instructions from mobile device 12 to acquire one or more images of display screen 69 during a subsequent period when display screen 69 of mobile device 12 is illuminated. Specifically, mobile device 12 illuminates display screen 69 to display an image that may include patterns of varying color contrast or may be a homogeneous color and brightness spectrum. One or more cameras 26 at evaluation module 10 then acquire or obtain at least one image of the illuminated display screen 69. In some cases, multiple images of display screen 69 may be acquired by one or more cameras 26 of evaluation module 10, with each of the multiple images capturing a different display image at mobile device 12.

[0229] Once the evaluation module 10 has acquired one or more images of the illuminated display screen 69, the evaluation module 10 performs image analysis to obtain information about the performance of the display screen 69. In particular, the analysis can identify areas of the display screen 69 or non-functional or poor-performing pixels in the display screen 69 (e.g., exhibiting poor performance across the color spectrum, or below the expected light level).

[0230] • Test the camera on the mobile device

[0231] Diagnostic tests can be performed to obtain information about the performance of at least one camera 50 at the mobile device 12. In other words, diagnostic tests can be performed to check that one or more cameras 50 at the mobile device 12 are working correctly and / or to evaluate the quality of the images they acquire. The described tests (including checking the functionality of all cameras, autofocus, telephoto, TrueDeepth, ultrawide, face ID) can be used, particularly in conjunction with the rotation of the mobile device 12 via a rotation mechanism, to evaluate the performance of the "front camera" and "rear camera" set up at the mobile device 12, as described below.

[0232] To perform this diagnostic test, the evaluation module 10 includes one or more graphic objects 36 arranged inside the housing. Specifically, the graphic object 36 is an image, picture, or symbol arranged on or mounted on the inner surface of the housing 16 so as to be opposite the outward-facing surface of the mobile device 12 placed in the evaluation area 24 within the cavity 14 of the housing 16 (when the housing is closed). For example, the graphic object 36 may include complex patterns in black and white (such as a quick response (QR) code) or an image comparing three or more colors (such as a color wheel). As discussed below, more than one graphic object 36 may be arranged on the surface inside the housing 16 to test different aspects of one or more cameras 50 of the mobile device.

[0233] To perform diagnostic testing, the camera 50 of the mobile device 12 acquires one or more images of a graphic object 36 arranged within the cavity 14 of the evaluation module 10. The evaluation module 10 then receives one or more images from the mobile device 12. In some cases, the evaluation module 10 illuminates the cavity 14 inside the housing 16 before the image is acquired by the camera 50 of the mobile device. For example, illumination can be provided by turning on an LED array 34 mounted inside the housing 16.

[0234] Evaluation module 10 performs analysis on one or more images of graphic objects 36 received from mobile device 12. The analysis aims to determine the quality of the images acquired by camera 50 at mobile device 12. The specific nature of the analysis depends on the specific graphic object 36 being imaged, as described below.

[0235] In one example, one of the one or more graphic objects 36 is a QR code. Evaluation module 10 analyzes the image of the QR code received from mobile device 12 to determine the performance of the autofocus function of camera 50 at mobile device 12. A summary of the determined autofocus performance can be included in the generated report.

[0236] In another example, one of the one or more graphic objects 36 is a graphic object or image that includes at least three colors. The evaluation module 10 performs an analysis on at least one image of the one or more graphic objects 36 to analyze the color accuracy of the at least three colors. A summary of the determined color accuracy can be included in the generated report.

[0237] It should be understood that the graphic object 36 can combine features suitable for testing the performance of the autofocus function of the camera 50 at the mobile device with features for testing the color accuracy of the camera 50 at the mobile device. Alternatively, two separate graphic objects 36 may exist arranged on the inner surface of the housing 16 of the evaluation module 10, and images of the two graphic objects 36 may be acquired by the mobile device 12 and sent to the evaluation module 10 for analysis.

[0238] It should be understood that the mobile device 12 may have one or more cameras 50. For example, the mobile device 12 may have a "front camera" on the same surface as the display screen and a "rear camera" on the surface opposite the display screen. The diagnostic tests described can be performed relative to any or all of the cameras on the mobile device. Thus, in some examples, a first camera on the mobile device 12 may be tested before the mobile device is rotated by the rotating mechanism described below, and a second camera on the mobile device 12 (on the surface opposite the first camera) may be tested after the mobile device is rotated.

[0239] Further diagnostic tests

[0240] Several other diagnostic tests can be performed on the mobile device 12, including but not limited to:

[0241] 1. Identifying the presence or absence of a SIM or eSIM – This involves receiving an indication from the mobile device 12 at the evaluation module 10 regarding the presence or absence of a physical or embedded SIM within the mobile device 12. The evaluation module 10 may also receive the results of a performance test assessing the ability of the identified physical or embedded SIM to connect to a telecommunications network. This test examines the connectivity capabilities of the mobile device 12.

[0242] 2. Testing the GNSS receiver – This involves receiving a geographic location signal from a Global Navigation Satellite System (GNSS) receiver 58 located at mobile device 12. The geographic location signal can be the location of mobile device 12 (e.g., longitude and latitude) measured by the mobile device using GNSS signals. Evaluation module 10 can then compare the location identified by mobile device 12 with a predetermined geographic location determined by evaluation module 10. This diagnostic test examines the performance and accuracy of the GNSS receiver 58 at the mobile device.

[0243] 3. Testing Bluetooth Capabilities – This involves establishing a Bluetooth connection between the evaluation module 10 and the mobile device 12, which aims to determine the functionality of Bluetooth capabilities at the mobile device 12. In other words, the evaluation module 10 may attempt to establish a Bluetooth connection, and if a connection is established, test communications may be exchanged. Whether the Bluetooth connection was successfully established can be included in the generated report. In some cases, the data connection 18 between the mobile device 12 and the evaluation module 10 used to exchange data for performing diagnostic tests may be a Bluetooth connection. However, alternatively, a Bluetooth connection may be established only as part of the diagnostic test.

[0244] 4. Testing WiFi Capability – This involves establishing a WiFi connection between the evaluation module 10 and the mobile device 12. This involves determining the WiFi capability at the location of the mobile device 12. In other words, the evaluation module 10 can attempt to establish a WiFi connection and exchange test communications. Whether the WiFi connection is successfully established can be included in the generated report. The ability of the mobile device 12 to provide a WiFi hotspot to other devices (i.e., the evaluation module 10 in the test scenario) can also be tested. In some cases, the data connection 18 between the mobile device 12 and the evaluation module 10 used to exchange data for performing diagnostic tests can be a WiFi connection (e.g., a connection to a WiFi hotspot generated by the evaluation module 10). However, alternatively, the WiFi connection can be established only as part of the diagnostic test.

[0245] 5. Assessing battery health involves receiving an assessment of the health status of the mobile device 12's battery from the mobile device 12 at the assessment module 10. In other words, the mobile device 12 can perform a self-assessment of its battery health and provide the results of that self-assessment to the assessment module 10. All or part of the self-assessment can be included in a subsequently generated report.

[0246] 6. Identification of Non-Original Components – This involves receiving information from the evaluation module 10 regarding the presence of any non-original components within the mobile device 12. The mobile device 12 is capable of scanning or evaluating its internal components (e.g., hardware components). Any non-original component (and its source as a manufactured or unmanufactured component) can be identified from the mobile device 12 to the evaluation module 10.

[0247] 7. Identifying the IMEI – This involves receiving the International Mobile Equipment Identity (IMEI) of the mobile device under evaluation from the mobile device 12 at the evaluation module 10. Based on the IMEI, the evaluation module 10 is able to determine the expected brand, model, color, and memory capacity of the mobile device 12 being tested.

[0248] 8. Testing the vibration motor – This involves receiving instructions from the mobile device 12 at the evaluation module 10 to initiate recording via microphone 28 of the evaluation module 10 during a subsequent activation period of the vibration motor 60 at the mobile device 12. The mobile device 12 can activate the vibration motor 60, and if the vibration motor 60 is successfully activated at the mobile device 12, sound will be recorded by the evaluation module 10 via microphone 28 at the housing 16 of the evaluation module 10. Therefore, the evaluation module 10 can determine whether the vibration motor 60 at the mobile device 12 is activated by analyzing the recording at microphone 28 during the activation period of the vibration motor 60 at the mobile device 12.

[0249] 9. Testing the camera flash – This involves receiving instructions from the mobile device 12 at the evaluation module 10 to initiate the acquisition of one or more images from one or more cameras 26 located at the housing 16 of the evaluation module 10 during illumination by the camera flash 62 at the mobile device 12. In this way, the evaluation module 10 can establish that the camera flash 62 at the mobile device 12 is operating as expected.

[0250] 10. Testing the light sensor or light level detector – This involves receiving a measurement of the light level at the light level sensor 52 at the mobile device 12 from the mobile device 12 at the evaluation module 10. In some cases, the light level or light intensity at the mobile device 12 can be measured before the mobile device is placed inside the housing 16 of the evaluation module 10. The mobile device 12 can measure the light intensity or light level at the light level detector 52 and return that measurement to the evaluation module 10 so that the evaluation module 10 can determine the performance of the light sensor 52 at the mobile device 12.

[0251] In an alternative, the diagnostic test occurs while the mobile device 12 is inside the housing of the evaluation module 10, and the diagnostic test further includes the evaluation module 10 illuminating one or more lighting devices 34 (e.g., as an LED array or bulb) within the housing 16 of the evaluation module 10 before measuring the light level at the mobile device 12. The mobile device 12 within the housing 16 can then measure the light intensity or light level at the light level sensor 52. In this example, the measured light level or intensity can be obtained by the evaluation module 10 and compared with the expected light level or intensity. In this example, the light level emitted by the lighting devices 34 within the housing 16 can vary over time, and the evaluation module 10 can establish that the light level sensor 52 correctly senses this change.

[0252] 11. Gyroscope Testing – This involves receiving measurements of orientation and / or angular velocity from the gyroscope 56 at the mobile device 12 at the evaluation module 10. This diagnostic test allows the evaluation module 10 to ensure that the gyroscope 56 at the mobile device 12 is functioning correctly. This diagnostic test can be performed before the mobile device 12 is placed within the housing 16 of the evaluation module 10 (although after a data connection has been established between the mobile device 12 and the evaluation module 10). In this case, the user can be instructed to move the mobile device 12 in some manner according to instructions from a software application or web browser-based diagnostic routine at the mobile device 12. In this way, changes in the orientation and angular velocity of the mobile device 12 can be generated by the user to allow appropriate measurements at the gyroscope 56 at the mobile device 12.

[0253] 12. Compass Test - This involves receiving measurements of the orientation of the mobile device 12 from the compass 48 at the mobile device 12 at the evaluation module 10. This diagnostic test allows the evaluation module 10 to ensure that the compass 48 at the mobile device 12 is functioning correctly. This diagnostic test can be performed before the mobile device 12 is placed inside the housing 16 of the evaluation module 10 (although after a data connection 18 has been established between the mobile device 12 and the evaluation module 10). In this case, the user can be instructed to move the mobile device 12 in some way according to instructions from a software application or web browser-based diagnostic routine at the mobile device 12. In this way, the orientation change of the mobile device 12 can be performed by the user to allow appropriate measurements to be taken at the compass 48 at the mobile device.

[0254] 13. Accelerometer Testing – This involves receiving measurements of the acceleration of the mobile device at the accelerometer 54 at the mobile device 12 from the mobile device 12 at the evaluation module 10. This diagnostic test allows the evaluation module 10 to ensure that the accelerometer 54 at the mobile device 12 is functioning correctly. This diagnostic test can be performed before the mobile device 12 is placed inside the housing 16 of the evaluation module 10 (although after a data connection 18 has been established between the mobile device 12 and the evaluation module 10), in which case the user can be instructed to move the mobile device 12 in some way (e.g., shake the device) according to instructions from a software application or web browser-based diagnostic routine at the mobile device 12.

[0255] 14. Testing the barometer – This involves receiving a measurement of the air pressure at the barometer located at the mobile device 12 from the mobile device 12 at the evaluation module 10. This diagnostic test allows the evaluation module 10 to ensure that the barometer at the mobile device is functioning correctly.

[0256] 15. Touchscreen Testing – This involves: in response to a command issued to a user of mobile device 12, receiving measurements at evaluation module 10 of one or more touch interactions received at different areas of the touchscreen 46 (which may also be a display screen 69) of mobile device 12 to provide touch input at different areas of touchscreen 46. This diagnostic test allows evaluation module 10 to ensure that the touchscreen 46 at mobile device 12 functions correctly (including touch response on all display points, multi-touch, 3D touch, touch ID).

[0257] In one example, a software application or web browser-based diagnostic routine on mobile device 12 can "guide" a user through a series of interactions, in which they request the user to touch different areas of touchscreen 46. Mobile device 12 can then obtain measurements of the touch response at each area of ​​touchscreen 46 on mobile device 12, which can be sent to or obtained by evaluation module 10. Assuming that the touch responses recorded on mobile device 12 should follow a predetermined sequence according to instructions provided to the user, the results obtained by evaluation module 10 can be used to determine whether each area of ​​touchscreen 46 (and the touch sensors therein) responds as expected. Thus, evaluation module 10 can determine the performance of touchscreen 46 on mobile device 12.

[0258] 16. Testing Button Functionality - This involves receiving, at evaluation module 10, indications from mobile device 12 regarding one or more buttons pressed by the user on mobile device 12 in response to instructions issued to the user of mobile device 12 (via a software application on the mobile device or a web browser-based diagnostic routine). This diagnostic test allows evaluation module 10 to ensure that any physical buttons on the device are functioning correctly.

[0259] 17. Testing Other Functions and Sensors – This involves receiving measurements from one or more additional sensors or functions at the mobile device 12 at the evaluation module 10 in response to an instruction issued to the user of the mobile device 12, to provide or enable appropriate input to the sensors or functions (e.g., input guided by a software application on the mobile device or a web browser-based diagnostic routine). These sensors may include proximity sensors, near-field communication (NFC) transceivers, Apple Pay capabilities, or QuickCharge capabilities. These diagnostic tests allow the evaluation module 10 to ensure that various other functions at the mobile device 12 are functioning correctly.

[0260] The rotating mechanism

[0261] As briefly discussed above, certain diagnostic tests benefit from the rotation of the mobile device 12 within the evaluation module 10. Specifically, the rotation of the mobile device 12 allows multiple images of the mobile device 12 to be captured by one or more cameras 26 within the evaluation module 10, each image showing a different aspect, angle, or surface of the mobile device 26. In particular, it is advantageous to obtain each of the multiple images at different stages of the rotation of the mobile device 12 to better observe scratches or defects on the surface of the mobile device 12.

[0262] It is also advantageous to enable the mobile device 12 to rotate so that both the "front camera" and the "rear camera" 50 can be tested at the mobile device 12. This requires the mobile device 12 to be rotated so that both the front camera and the rear camera 50 are arranged opposite the graphic object 36 used to test the camera 50 at the mobile device 12, as described above.

[0263] The mechanism for rotating the mobile device 12 needs to rotate in a controlled manner so that the mobile device 12 does not experience any sudden drops or unsupported movements that could cause damage. Furthermore, the rotating mechanism must be able to operate in conjunction with mobile devices of different shapes and sizes. The inventors have developed a rotating mechanism to achieve these objectives.

[0264] Figures 5 to 11 Different stages of rotation of the mobile device 12 within the evaluation module 10 are illustrated using the rotation mechanism 100. The rotation mechanism 100 has a base plate or base portion 105, which is the lower portion or support section of the sliding tray 70 of the housing 16 as described above. The base portion 105 has a fixed orientation compared to the wall of the housing 16.

[0265] The rotating mechanism 100 also includes a flat support plate 110, which is movable between a first position parallel to the upper surface 115 of the base portion 105 and a second position at an angle to the upper surface 115 of the base portion 105. The movement of the flat support plate 110 is actuated by an actuating element or a movable arm 120, the first end of which is hingedly connected to a connector at the flat support plate 110, and the second end of which is hingedly connected to the base portion 105.

[0266] The rotating mechanism 100 also includes a concave support plate 125, which is arranged at a fixed angle to the upper surface 115 of the base 105. The concave support plate 125 is used to receive the mobile device 12 during rotation, as described below.

[0267] In the first stage of rotation (in) Figure 5 As shown in the figure, Figure 5 (a) is a stereoscopic view, and Figure 5(b) is a cross-sectional view. The mobile device 12 is arranged by the user or operator of the evaluation module 10 on the platform of the sliding tray 70 (i.e., in the evaluation area 24). The mobile device 12 is supported at least partially by a flat support plate 110. In the example shown, the mobile device 12 has its display side (first side) facing outwards into the open cavity of the evaluation module 12. The camera 26 (which may be one of a plurality of cameras, as described above) is arranged directly above the mobile device 12 located in the evaluation area 24.

[0268] Figure 6 A cross-sectional view of the rotating mechanism 100 during the second rotation phase is shown. As shown, rotation of the actuating element 120 relative to the base portion 105 causes the flat support plate 110 to pivot relative to the second end of the actuating element 120. This causes the flat support plate 110 to tilt from its first position (parallel to the upper surface 115 of the base portion 105) to a second position (angled with the upper surface 115 of the base portion 105). As a result, the mobile device 12 is pivoted about one of its edges 130 to rotate or tilt the mobile device 12 relative to the upper surface 115 of the base portion 105.

[0269] The actuating element 120 continues to rotate in a controlled manner until the flat support plate 110 has rotated approximately 90° relative to its initial position. Simultaneously, the concave support plate 125 moves linearly toward the flat support plate 110 to push the mobile device 12 (particularly its edge 130 around which it pivots) toward the flat support plate 110, ensuring that the mobile device 12 is fully supported by the flat support plate 110 during this rotational phase (see [link]). Figure 7 ).

[0270] The rotation of the flat support plate 110 continues until it has rotated more than 90° relative to its initial position. At this point, the mobile device 12 tilts or pivots at its edge 130 toward the concave support plate 125 and away from the flat support plate 110, so that, compared to its initial position, the mobile device 12 has rotated more than 90 degrees around one edge 130 of its initial position. As the concave support plate 125 has moved toward the flat support plate 110, it receives the mobile device 12 and now supports it. This... Figure 8 The text is a mix of Chinese characters and symbols, making it impossible to translate accurately. It appears to be a collection of fragments from various sources Figure 8 (a) is a stereoscopic view, and Figure 8 (b) is a sectional view.

[0271] Next, the concave support plate 125 is moved away from the flat support plate 110 to increase the gap between the concave support plate 125 and the flat support plate 110 (see...). Figure 9This causes the mobile device 12 to pivot further around one of its edges 130, so that the face of the mobile device 12 that was initially facing the cavity 14 of the housing 16 of the evaluation module 10 now faces the upper surface 115 of the base portion 105, while the opposite face now faces outward into the cavity 14 (and toward the camera 26 mounted above).

[0272] Finally, the concave support plate 125 moves back to its original position, and the flat support plate 110 rotates back to its original position parallel to the upper surface 115 of the base portion 105 (see [link]). Figure 10 ,in Figure 10 (a) is a stereoscopic view, and Figure 10 (b) is a cross-sectional view. This arranges the mobile device 12 substantially flat (i.e., parallel to the upper surface 115 of the base portion 105), but with the second surface of the mobile device 12 facing outwards into the cavity 14 of the housing 16. Thus, the mobile device 12 has been rotated 180° around one edge 130 of the mobile device 12 compared to its original starting position. The mobile device 12 has been rotated (see [reference]) when the sliding tray 70 of the housing 16 is opened to allow the user to remove the mobile device 12 from the evaluation module 10 (e.g., by sliding out of the sliding tray 70 of the evaluation module 10). Figure 11 ).

[0273] It should be understood that, advantageously, images can be captured by one or more cameras 26 of the evaluation module 10 at various stages of rotation to obtain images of different surfaces (including edges) of the mobile device 12. Ideally, more than one camera 26 is mounted within the evaluation module 10 so that each edge of the mobile device 12 can be imaged by the evaluation module 10. It should be understood that smaller scratches on the surface of the mobile device 12 may only be visible from certain angles, and therefore rotation of the mobile device 12 is particularly useful for better evaluating the appearance condition of the mobile device 12.

[0274] The concave shape of the concave support plate 125 offers various advantages compared to the flat support plate 110. Figure 12 from Figure 8The angle of camera 26 in (b) shows a concave support plate 125 within the housing 16 mounted above the evaluation area 24. Specifically, the concave support plate 125 is configured to receive the mobile device 12 such that it contacts the mobile device 12 at a portion of the peripheral edge of its second side. The geometry of the concave support plate 125 helps ensure that the mobile device 12 is supported throughout rotation. The smooth, protruding edges of the plate 125 not only hold the tested mobile device 12 in the desired position but also enable testing of devices of various sizes. The concave support plate 125 is shaped to allow rotation of mobile devices of various shapes and sizes, including foldable mobile devices. This mechanism ensures reliable and safe rotation of both standard phones and foldable devices with dimensions up to 160mm × 130mm and internal displays with a diagonal measurement of 7.6 inches (e.g., the Galaxy Z fold).
