Detailed Implementation

[0026] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. Those skilled in the art will understand that they merely illustrate exemplary ways that can be used to implement this disclosure, and are not exhaustive.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] In related technologies, lighting equipment used for vehicle interiors typically includes ambient lighting that decorates the vehicle and creates an atmosphere. Its main forms of expression are color changes, breathing rhythms, and audio rhythms. When users are in the car, they can control the ambient lighting to turn on / off, adjust brightness, and switch colors via switches on the control panel. These operations require users to press the switches on the control panel, which is usually located near the driver. This makes it difficult for passengers in other seats to make convenient adjustments. Furthermore, the light effect change patterns are preset and fixed, making it difficult to achieve refined lighting effects and affecting the user's interaction experience with the vehicle.

[0031] Based on the above, this disclosure provides a control method for lighting equipment on vehicle door panels. This method identifies the user's hand movements within the corresponding light effect interaction area on the door panel, recognizes the user's input signals to the door panel, identifies the position coordinates of the user's fingers based on the interaction signals, and then determines the specific optical parameters for displaying light effect patterns on the door panel based on these position coordinates. This approach improves the vehicle's interactive perception and real-time response capabilities, including enabling designated light effect display areas such as vehicle door panels to display rich light effects that follow the user's movements. It achieves personalized control of the lighting equipment, creates an engaging light and shadow atmosphere, and enhances the user's interactive experience while riding in the vehicle.

[0032] The control method for lighting equipment used in vehicle interiors will now be described in detail with reference to the accompanying drawings. It will be understood that the actual method may include other steps, but to avoid obscuring the key points of this disclosure, these other steps are not shown in the drawings and will not be discussed herein.

[0033] Please refer to the following first. Figure 1 The diagram illustrates a schematic flowchart of a control method 100 for a lighting device for a vehicle door panel according to some embodiments of the present disclosure. Specifically, the control method 100 includes steps S102 to S108. In step S102, in response to a user's hand movement in the light effect interaction area of ​​the door panel, an interaction signal from the user to the door panel is acquired. In step S104, based on the interaction signal, the position coordinates of the user's finger relative to the light effect interaction area are identified. In step S106, using an interaction model, based on the interaction signal and the position coordinates, optical parameters of the light effect display area of ​​the door panel are determined. And in step S108, based on the optical parameters, the lighting device of the door panel is controlled.

[0034] In this article, "occupant" refers to a person located inside the vehicle, including but not limited to the driver and passengers. "User" refers to an occupant who uses the light-effect interaction function of the vehicle door panel. It is understood that, considering driving safety requirements and the distance between the passenger seat and the door panel, the user who interacts with the door panel usually refers to the passenger seated by the window.

[0035] refer to Figure 2A and Figure 2BThe diagram illustrates a light effect display area and a light effect interaction area on a vehicle door panel according to some embodiments of the present disclosure. Generally, lighting devices for vehicle interiors can be distributed in multiple locations within the vehicle, including but not limited to the door panel (DP) area, instrument panel (IP) area, roof area, and footwell, etc., with each lighting device having fixed three-dimensional coordinates within the vehicle interior space. In the embodiments of the present disclosure, the lighting devices that form interactive light effects on the door panel are typically located near the door panel DP area; however, it is understood that lighting devices in other areas of the vehicle interior can also be used to output light effect patterns on the door panel, which will not be elaborated upon here.

[0036] Specifically, Figure 2A A perspective view of a vehicle door panel is shown, in which a light effect display area 20 is disposed on the inner surface of the door panel, between the window (not shown) and the door retractor structure. Figure 2B It is along Figure 2A The cross-sectional view in the direction of the arrow shows that lighting devices 11-1 and 11-2 (collectively referred to as lighting device 11) are arranged in the upper and lower parts of the light effect display area 20, respectively. In some embodiments, the lighting device 11 may include a sequential array of light sources, which can be controlled individually or in groups to achieve the effect of illuminating the entire light effect display area 20 or illuminating a specific area therein. Further, the light effect interaction area 21 refers to the spatial area for collecting, sensing, or recognizing user hand movements, and can be located near the light effect display area 20 and corresponding to the size dimensions of the light effect display area 20 (e.g., ...). Figure 2B (As shown), it can also be placed in a wider range of spaces inside the vehicle, as long as the boundaries are clear and it is convenient for users to make movements while riding.

[0037] In some embodiments, user hand gestures in the light effect interaction area 21 include both contactless proximity sensing and contact touch operations. The light effect display area 20 can be a soft surface or a hard surface to match the recognition method of the user's hand gestures. Specifically, when the hand gesture to be recognized is a touch operation, the light effect display area 20 needs to be equipped with internal devices such as pressure sensing devices, and the surface material of the light effect display area 20 should be determined in conjunction with the sensitivity of the pressure sensing device; when the hand gesture to be recognized is proximity sensing, the requirements for the surface material of the light effect display area 20 will be reduced accordingly.

[0038] For details, please refer to Figures 3A to 3D The diagram illustrates a pressure sensing device for a vehicle door panel according to some embodiments of the present disclosure. In some embodiments, a user's hand movements in the light-effect interaction area include touching the pressure sensing device of the door panel. Figure 1Step S102, which involves collecting user interaction signals with the door panel, may include determining the interaction signal based on sensing data identified by the pressure sensing device. The interaction signal includes the pressing position and / or pressure value of the finger, wherein the pressing position corresponds to the position coordinates of the user's finger relative to the light effect interaction area.

[0039] like Figure 3A As shown, the pressure sensing device includes a contact surface 30 disposed on the door panel and a pressure diaphragm 32 disposed inside the door panel corresponding to the contact surface 30. In a non-limiting embodiment, the contact surface 30 may be made of a hard 3D textured surface material to improve the sensitivity of pressure sensing. Figure 3B It shows Figure 3A The enlarged structure of the dashed frame includes a contact surface 30 fixedly supported by a contact surface support layer 31, and a pressure diaphragm 32 positioned and supported by a pressure diaphragm positioning layer 33. These four layers are arranged in sequence to form a pressure sensing device for recognizing touch actions.

[0040] Furthermore, Figure 3C A planar schematic diagram of a pressure diaphragm 32 is shown. The pressure diaphragm 32 includes a flexible membrane 321 and an identification element 322 disposed thereon. In a non-limiting embodiment, the number and distribution of the identification elements 322 can be determined based on at least one of factors such as the area of ​​the pressure diaphragm 32, the sensing accuracy of the identification element 322, and the material of the contact surface 30. Figure 3C A non-limiting example of an array of recognition elements 322 disposed on a flexible membrane 321 is shown. Additionally, Figure 3D A perspective view of the contact surface 30 is shown, on which pressure detection points 302 are provided for detecting the pressure position of the user's touch action. It is understood that the number and distribution of the pressure detection points 302 should be the same as or correspond to the recognition element 322 in order to improve the sensing accuracy of the pressure sensing device.

[0041] Alternatively, please refer to Figure 4 The diagram illustrates a capacitive sensing device for a vehicle door panel according to some embodiments of the present disclosure. In some embodiments, a user's hand movement in the light effect interaction area includes approaching the capacitive sensing device of the door panel. Figure 1 Step S102 may further include using a capacitance sensing device as an interaction signal sensing device, and using a capacitance signal determined based on a detection interval as an interaction signal.

[0042] Specifically, the capacitive sensing device includes a sensing surface 40 disposed on the door panel and a capacitive diaphragm 42 disposed inside the door panel corresponding to the sensing surface 40. It is understood that, since the user may not directly contact the door panel surface, the sensing surface 40 can be made of a soft 3D textured material. Similar to... Figure 3BThe structure includes a sensing surface 40 fixedly supported by a sensing surface support layer 41, and a capacitor diaphragm 42 positioned and supported by a capacitor diaphragm positioning layer 43. When a user's finger approaches the sensing surface 40, the original electric field of the capacitor diaphragm 42 changes, and the resulting change in capacitance can be output as a capacitance signal.

[0043] In some embodiments, the capacitance signal can be used to calculate the proximity distance of the user's finger relative to the light effect interaction area and the coordinates of the finger's projected position in the light effect interaction area. For example, in a spatial rectangular coordinate system, the direction of the proximity distance can be taken as the Y-axis, and the coordinates of the projected position can be marked as (X, Z). In a non-limiting embodiment, the process of obtaining the aforementioned coordinates based on the capacitance signal may include: periodically acquiring electrode capacitance signals by the capacitor diaphragm 42 according to a resident detection interval; calculating capacitance data in real time and determining whether the capacitance change corresponding to the capacitance signal triggers a threshold; in response to the capacitance signal reaching the threshold, calculating the distance between the user's finger and the capacitor diaphragm, and then, in combination with the signal distribution of the electrodes on the capacitor diaphragm 42, outputting the detailed position coordinates of the finger.

[0044] Alternatively, please refer to Figure 5 The diagram illustrates an imaging device for a vehicle door panel according to some embodiments of the present disclosure. In some embodiments, a user's hand movements in the light effect interaction area can be captured by the imaging device. Specifically, imaging devices 51-1 and 51-2 (collectively referred to as imaging device 51) are respectively provided on the upper and lower parts corresponding to the light effect display area 20 of the vehicle door panel. It is understood that the number and position of the imaging devices 51 can be customized while meeting the requirements of the vehicle's interior structure and without affecting the light effect pattern of the lighting equipment.

[0045] In a non-limiting embodiment, when a user makes a hand gesture within the light effect interaction area, the imaging device 51 acquires an image of the hand in real time and performs data analysis to determine the imaging position of the finger at the moment of image acquisition as an interaction signal. Figure 4 Similar to the implementation, based on the interaction signal, the proximity distance of the finger relative to the light effect interaction area and the coordinates of the finger's projection position in the light effect interaction area can be calculated.

[0046] Continue to refer to Figure 1 Next, in step S106, based on the interaction signal collected by the aforementioned sensing device and the position coordinates identified by the corresponding data processing operation, the optical parameters of the light effect display area are determined to form an interactive pattern. In some embodiments, the interactive pattern in the light effect display area is defined using an interaction model, and determining its optical parameters includes processing the position coordinates based on the type of the interactive pattern to determine the display position of the interactive pattern in the light effect display area.

[0047] For details, please refer to Figures 6A to 6C The illustration shows a schematic diagram of forming an interactive pattern in a light effect display area according to some embodiments of the present disclosure. Figure 6A The initial state of the light effect display area is shown, where the projection of the light effect interaction area onto the light effect display area determines the size of the area ABDC. Figure 2B The lighting devices 11 shown are located at the top of side AB and the bottom of side CD in the area, forming the initial lighting area EFHG (i.e., the shadowed part and the unshadowed part show different lighting effects). Figure 6B The coordinates P of the user's finger relative to the light effect interaction area are shown, denoted as (X0, Z0). When the finger approaches or touches the light effect interaction area, the light effect display area can be presented as follows: Figure 6C The pattern, in which the two sides EF and GH of the initial light area EFHG form a change in light effect near the position coordinate P.

[0048] In a non-limiting embodiment, such as Figure 6C As shown, the endpoints A of the light effect display area are denoted as (X1, Z1), B as (X2, Z2), C as (X3, Z3), and D as (X4, Z4); the endpoints E of the initial light area are denoted as (X5, Z5), F as (X6, Z6), G as (X7, Z7), and H as (X8, Z8); the endpoints M of the light effect change area are denoted as (X9, Z9), and N as (X1, Z2). 10 Z 10 ), I is denoted as (X 11 Z 11 J is denoted as (X) 12 Z 12 K is denoted as (X 13 Z 13 L is denoted as (X) 14 Z 14 The positions of M and N can be determined using the following relationship:

[0049] Therefore, endpoints M and N, and their coordinate distances from endpoints I, J, K, and L, can affect the shape and area of ​​the light effect variation region. That is, the pattern dividing the light effect variation region with the finger coordinate position P as the origin can be represented by the trajectory from I to M as , the trajectory from M to J as , the trajectory from K to N as , and the trajectory from N to L as .

[0050] The changes in the light effect above the light effect display area can be controlled according to the following expression:

[0051] The changes in light effects below the light effect display area can be controlled using the following expression:

[0052] Furthermore, in some embodiments, the type of interaction pattern can be defined by the interaction model as at least one of pulse type, parabolic type, normal distribution type, and chord curve type.

[0053] Specifically, Figures 7A to 7E The diagram illustrates an interaction pattern defined by a pulse-type interaction model, where the presented pulse interaction pattern primarily comprises rectangular square waves. It can be understood that the coordinates of points M and N are used to define the pulse width (or duty cycle) of the upper light effect change and its amplitude; and to define the pulse width of the lower light effect change and its amplitude. Specifically, Figure 7A The diagram shows pulse-shaped interactive patterns with opposite directions formed by the changes in light effects above and below the light effect display area. This can produce the effect that the peak positions of the two square waves move from the top and bottom towards the center line and follow point P.

[0054] Alternatively, Figure 7B and Figure 7C Another non-limiting example of a pulsed interactive pattern is shown, wherein when the finger position coordinate P is above the horizontal midline of the light effect display area ABDC, only the lower light effect changes to form the pulsed pattern, while the upper light remains unchanged; when point P is below the horizontal midline, only the upper light effect changes to form the pulsed pattern, while the lower light remains unchanged. Alternatively, Figure 7D and Figure 7E Another non-limiting example of a pulse interaction pattern is shown, wherein when the finger position coordinate P moves in the light effect display area, and specifically moves to a range outside the initial light area EFHG, the upper and lower light effect changes form pulse-shaped patterns with the same direction, and the peak direction is from the center line toward the position of point P.

[0055] In other embodiments, Figures 8A to 8E The diagram shows a set of interactive patterns defined by normal distribution or parabolic interaction models. Referring to the aforementioned expression, controlling the change in light effect must satisfy the following:

[0056] Similarly, Figure 8A The pattern shows that the light effect changes in opposite directions on both sides of the light effect display area, wherein the peak position of the light effect pattern moves from the top and bottom towards the center line and follows point P. Figure 8B and 8C A pattern showing a unilateral change in the light effect display area is illustrated; and Figure 8D and Figure 8E The diagram shows patterns on both sides of the light effect display area where the direction of light effect change is the same, and the direction of the peak of the light effect pattern is from the center line toward point P.

[0057] In yet other embodiments, Figures 9A to 9E A set of schematic diagrams defining interaction patterns using a chord-curve type interaction model is shown. For illustrative purposes, trigonometric functions (such as sin) are used in this disclosure. x cos x (etc.) and functions with similar oscillatory properties composed of trigonometric functions (such as sinc) x ,cosc x The graphs of (etc.) are collectively referred to as chord curve type. Figures 9A to 9E The interactive pattern is a non-limiting example of the latter. Referring to the aforementioned expression, controlling the change in light effect can satisfy any of the following relationships: or

[0058] Alternatively, controlling the change in light effect can also satisfy other functional relationships:

[0059] Similarly, Figure 9A It is a pattern in which the light effect changes in opposite directions on both sides of the light effect display area, wherein the peak position of the chord curve pattern moves from the top and bottom towards the center line and does not exceed the horizontal line where point P is located; Figure 9B and 9C A pattern showing a unilateral change in light effect in the light effect display area is shown; Figure 9D The diagram shows a pattern where the direction of light effect change is the same on both sides of the light effect display area, wherein the direction of the peak of the chord curve is from the midline towards point P; and Figure 9E It shows Figure 9AAnother form of interactive pattern in which the peak of the chord curve pattern is directed from the upper and lower sides AB and CD of the light effect display area toward point P, and exceeds the horizontal line where point P is located, thus forming a light effect pattern in which the curves overlap.

[0060] In some embodiments, the optical parameters of the light effect display area include, in addition to the display position of the interactive pattern, the shape, brightness, and color of the interactive pattern. Specifically, the optical parameters such as the shape of the interactive pattern can be determined based on the intensity of the interactive signal, such as in... Figure 8A In the example shown in 9A, the stronger the collected interactive signal, the higher the peak value of the displayed interactive pattern can be controlled, thereby enhancing the interactive experience of the light effect display function for the user.

[0061] In a non-limiting embodiment, reference is made to Figure 3A In the example, when the recognized user hand action includes touching the pressure sensing device on the door panel, the collected interaction signal includes the pressing position and / or pressure value of the user's finger, wherein the pressing position determines the display position of the interactive pattern, and / or the pressure value determines at least one of the shape, brightness, and color of the interactive pattern. For example, in response to greater user pressure, the interactive pattern may be brighter, have a larger peak value, and a deeper color. It is understood that the correspondence between pressure values ​​and different optical parameters can be personalized and preset according to requirements.

[0062] In another non-limiting embodiment, reference is made to... Figure 4 or Figure 5 For example, when the detected user hand movement is not in contact with the door panel, the collected interaction signals include the proximity distance of the user's finger and the coordinates of its projected position. The projection position coordinates determine the display position of the interactive pattern, and / or the proximity distance determines other optical parameters of the interactive pattern. For instance, the closer the user's finger is to the door panel, the brighter and larger the peak value of the interactive pattern can be. Furthermore, if the user's finger continuously changes its proximity distance during movement, the light color of the interactive pattern can change accordingly.

[0063] For the purpose of non-restrictive description, Figure 10 A flowchart illustrating a non-limiting example process 1000 of a control method for a lighting device for a vehicle door panel according to some embodiments of the present disclosure is shown. Figure 10 As shown, process 1000 includes steps S1001 to S1008.

[0064] In step S1001, the lighting equipment on the vehicle door panel is powered on, and the user can begin using the interactive function. When no user hand gestures are detected, the corresponding lighting equipment remains in its normal state, such as maintaining the preset light color and not displaying any light effect patterns (see reference). Figure 6A (Example). In step S1002, in response to the user's hand movement in the light effect interaction area of ​​the door panel, the user's interaction signal with the door panel is acquired. Next, in step S1003, the position coordinates of the user's finger are identified based on the acquired interaction signal.

[0065] Further, in step S1004, using an interactive model, the optical parameters of the light effect display area of ​​the door panel are determined based on the interactive signal acquired in step S1002 and the position coordinates identified in step S1003. Then, in step S1006, the lighting device of the door panel is controlled to form a corresponding light effect pattern according to the determined optical parameters.

[0066] Additionally, in step S1007, the interactive model can be personalized to generate light effect patterns of different shapes. Furthermore, in step S1008, the interactive signal (denoted as 1002) acquired in step S1002 and the finger position coordinates (denoted as 1003) identified in step S1003 can be further processed for invoking vehicle system functions, specifically including invoking the function of controlling the in-vehicle lighting equipment (i.e., the operation in step S1006).

[0067] Furthermore, Figure 11 A flowchart illustrating a non-limiting example of invoking the vehicle's infotainment system (step S1008) in process 1000 described above is shown. Data processing of the interaction signal 1002 and position coordinates 1003 includes steps S1101 to S1105. Specifically, in step S1101, the received signal is filtered to suppress environmental noise, jitter interference, and invalid spurious signals during vehicle movement, avoiding misjudgments and false triggers. Next, in step S1102, a gesture recognition algorithm is used to identify the command gestures represented by the interaction signal 1002 and position coordinates 1003 to distinguish different action types and exclude invalid actions. The gesture recognition algorithm can use template matching, feature classification, or deep learning models. In step S1103, a dynamic threshold is set to adapt to changes in the vehicle's environment and user differences, ensuring the stability of action recognition.

[0068] Subsequently, in step S1104, the identified command gesture is subjected to a region dwell determination to determine the dwell state of the command gesture within a preset spatial area, thereby confirming that the user's gesture is a conscious pause rather than an accidental swipe (i.e., the validity of the command). Then, in step S1105, based on the dwell state and the movement parameters of the command gesture, a spatial region-based mapping output is executed, including mapping different spatial regions and command gestures to specific function parameters according to a preset vehicle system function mapping table or function retrieval command, thereby outputting the corresponding control command.

[0069] Additionally, the mapping output may include preset event codes corresponding to optical parameters. In some embodiments, different user gestures for the lighting device can be mapped to specific parameter adjustment events, such as a swipe gesture from bottom to top in the corresponding light effect interaction area of ​​the door panel, which corresponds to an event of increasing the brightness of the light effect display area; a swipe gesture from left to right, which corresponds to an event of switching colors, etc. Based on this, the control commands output in step S1105 include commands for adjusting the parameters of the lighting device based on the aforementioned preset event codes.

[0070] In some embodiments, control commands may include, but are not limited to, commands for controlling windows and sunshades, commands for adjusting comfort seats, commands for adjusting air conditioning and ventilation, commands for adjusting multimedia volume, and other commands personalized by the user, to complete the interaction loop. In particular, these vehicle infotainment functions also include the ability to display lighting effects on the door panels, meaning that corresponding lighting devices can be controlled by recognizing the user's gesture commands.

[0071] On the other hand, this disclosure also provides another lighting control device for vehicle door panels. Figure 12 A schematic block diagram of a control device 1200 according to some embodiments of the present disclosure is shown. The control device 1200 includes a data acquisition module 1202, a calculation module 1204, a determination module 1206, and a control module 1208.

The determination module 1206 is configured to determine the optical parameters of the light effect display area of ​​the door panel using an interaction model, based on the interaction signals and position coordinates. The control module 1208 is configured to control the lighting device of the door panel based on the optical parameters.

The computer system 1500 includes a bus 1502 or other communication mechanism for transmitting information, and a processing means 1504 coupled to the bus 1502 for processing information. The computer system 1500 also includes a memory 1506 coupled to the bus 1502 for storing instructions to be executed by the processing means 1504. The memory 1506 may be random access memory (RAM) or other dynamic storage device.

The computer system 1500 also includes a read-only memory (ROM) 1508 or other static storage device coupled to the bus 1502 for storing static information and instructions for the processing means 1504. A storage device 1510, such as a magnetic disk or optical disk, is provided and coupled to the bus 1502 for storing information and instructions. Computer system 1500 may be coupled via bus 1502 to output device 1512 for providing output to a user, such as, but not limited to, a display (such as a cathode ray tube (CRT) or liquid crystal display (LCD)), speakers, etc. Input device 1514, such as a keyboard, mouse, microphone, etc., is coupled to bus 1502 for transmitting information and command selections to processing device 1504. Computer system 1500 may perform embodiments of this disclosure. Consistent with certain implementations of this disclosure, computer system 1500 provides results in response to processing device 1504 executing one or more sequences of one or more instructions contained in memory 1506. Such instructions may be read into memory 1506 from another computer-readable medium, such as storage device 1510. Execution of the sequence of instructions contained in memory 1506 causes processing device 1504 to perform the methods described herein. Alternatively, hard-wired circuitry may be used in place of or in combination with software instructions to implement the teachings. Therefore, implementations of this disclosure are not limited to any particular combination of hardware circuitry and software. In various embodiments, computer system 1500 may be connected across a network to one or more other computer systems, such as computer system 1500, to form a networked system via network interface 1516. This network may include a private network or a public network such as the Internet. In a networked system, one or more computer systems may store data and supply data to other computer systems. As used herein, the term "computer-readable medium" refers to any medium that participates in providing instructions to processing device 1504 for execution. Such media may take many forms, including but not limited to non-volatile media, volatile media, and transmission media. Non-volatile media include, for example, optical discs or magnetic disks such as storage device 1510. Volatile media include dynamic memory such as memory 1506.Transmission media include coaxial cable, copper wire, and optical fiber, including cabling containing bus 1502. Common forms of computer-readable media or computer program products include, for example, floppy disks, flexible disks, hard disks, magnetic tape, or any other magnetic media, CD-ROMs, digital video discs (DVDs), Blu-ray discs, any other optical media, thumb drives, memory cards, RAM, PROMs and EPROMs, fast EPROMs, any other memory chips or cartridges, or any other tangible media from which a computer can read. Various forms of computer-readable media may be involved when carrying one or more sequences of one or more instructions to processing device 1504 for execution. For example, instructions may initially be carried on a disk of a remote computer. The remote computer may load the instructions into its dynamic memory and transmit the instructions over a telephone line using a modem. A modem local to computer system 1500 may receive data over a telephone line and convert the data into an infrared signal using an infrared transmitter. An infrared detector coupled to bus 1502 may receive the data carried in the infrared signal and place the data on bus 1502. Bus 1502 carries data to memory 1506, and processing device 1504 retrieves instructions from memory 1506 and executes the instructions. Optionally, instructions received by memory 1506 may be stored on storage device 1510 before or after execution by processing device 1504.

[0078] According to various embodiments, instructions configured to be executed by a processing device to perform a method are stored on a computer-readable medium.
