In various embodiments, the vessel 826 can contain a calibration standard fluid having a specified expected reference substance concentration. In the embodiment of FIGS. 7- 8, the vessel 826 is a compressed gas cylinder and the calibration standard fluid is a pressurized reference gas. In alternate configurations, the calibration standard fluid can be a liquid solution or can take a non-fluid form such as capsules, cartridges, or the like.

[0089] In various embodiments, the reference substance of the calibration standard fluid can be ethanol. Such a calibration standard fluid can be used to calibrate a substance tester device 100 with a detection element 105 configured to measure the alcohol concentration in a user’s breath or other sample. It is also possible for other substances and compounds to be detected by a detection element 105, such as different intoxicants, prescription drugs, cannabis, cocaine, heroin, nicotine, methamphetamine, amphetamines, hallucinogens, or other substances. In such embodiments, the reference substance of the calibration standard fluid can be selected to calibrate the detection element to detect the selected substance.

[0090] In various embodiments, the calibration standard fluid source subassembly 206 can include a fluid interface 828 configured to receive the calibration standard fluid from the vessel 826. The fluid interface 828 can include a valve 829 configured to selectively restrict the flow of the calibration standard fluid. It is herein contemplated that the valve 829 can be a variety of different valves. For example, the valve 829 can include a solenoid valve, a butterfly valve, a diaphragm valve, a gauge valve, a check valve, and the like. In various embodiments, when the valve 829 of the fluid interface 828 is in an open state, the calibration standard fluid is free to flow from the vessel 826 to the second calibration station port 520.

[0091] In various embodiments, the calibration standard fluid source subassembly 206 can include tubing 832. The tubing 832 is configured to fluidically connect the vessel 826 to the second calibration station port 520.

[0092] In various embodiments, the calibration standard fluid source subassembly 206 can include a circuit board 830. The circuit board 830 can include a second calibration station port 518 that is connected to the vessel 826 via tubing 832. The circuit board 830 can further include the first calibration station port 518. In some embodiments, the first calibration station port 518 can be connected to the fluid interface 828 via one or more wires 831.

[0093] In various embodiments, receiving the calibration initiation signal from the tester controller causes the fluid interface 828 to open such that the calibration standard fluid flows to the detection element 105 via a second calibration station port 520 and the second tester port 312. In the example of FIGS. 7-8, the calibration initiation signal can be received at the first calibration station port and can be transmitted to the fluid interface 828 via the wires 831. The calibration initiation signal can cause the valve 829 to open, allowing the calibration standard fluid to flow from the vessel 826 to the second calibration station port 520. In some embodiments, the valve 829 is configured to remain in its closed state and to only open upon receiving the calibration initiation signal from the tester controller. Fluid Delivery Configurations (FIGS. 10-12)

[0094] FIGS. 10-12 illustrate alternative configurations for fluid delivery structures within a substance tester device to provide a fluid from a second tester port to a detection element. Referring first to FIG. 10, a schematic view of a portion of a substance tester device is shown in accordance with various embodiments herein, in which the fluid is delivered to the outlet of the breath path 114. In various embodiments, the substance tester device 100 can contain all of the components needed to detect a substance concentration in a breath sample airflow.

[0095] In various embodiments, the substance tester device 100 can include a breath path 114. The breath path 114 can be in fluid communication with the mouthpiece 112. The user can provide a breath sample by blowing into the mouthpiece 112. The breath sample can travel down the breath path 114. A portion of the breath sample can exit the device via the breath path outlet 1035 and a portion of the breath sample can be drawn into the detection element 105.

[0096] In various embodiments, the substance tester device 100 can include a detection element 105. In various embodiments, the detection element 105 can be an electrochemical sensor, such as a fuel cell-type detector element, and converts alcohol content within the breath sample to a measurable electrical signal. The detection element 105 can include a sampling port 1041 configured to withdraw a portion of the breath sample from the breath path 114 to be tested for alcohol content. The sampling port 1041 provides a passage into a detection element 105 of the substance tester device 100. The detection element 105 is configured to catalytically combine any alcohol in a sample introduced into the fuel cell through sampling port 1041 with oxygen to create an electrical signal that is amplified and measured to determine an alcohol concentration in the breath sample in a known fashion.

[0097] Additionally, or alternatively to a fuel cell detection element, the system can include one or more of a complementary metal oxide semiconductor (CMOS) sensor, a metal oxide semiconductor (MOS) sensor, a semiconductor sensor, and an infrared (IR) sensor.

[0098] In some examples, detection elements can be used to provide a continuous signal. Detection elements for alcohol that can provide a continuous signal are a complementary metal oxide semiconductor (CMOS) sensor, a metal oxide semiconductor (MOS) sensor, a semiconductor sensor, and an infrared (IR) sensor. These detection elements and detection elements that provide a continuous signal do not need to wait for a predetermined time period after receiving a gas sample to provide a gas alcohol content reading that is considered accurate. In contrast, fuel cell detection elements operate on a fixed volume gas sample when measuring alcohol content.

[0099] In other examples, instead of testing a user’s breath for alcohol, the detection unit can test the user’s breath for cannabis, opioids, or other intoxicants. In other examples, instead of testing the user’s breath for an intoxicant, the detection unit can be a transdermal device that is in contact with the user’s skin and detects a level of alcohol, cannabis, opioids, or other intoxicants in a user. Transdermal sensors can be part of a wrist-worn device, an ankle-worn device, a device attached to another part of the user’s body, or a device embedded in a steering wheel or another part of the vehicle. If a transdermal unit is used as the detection unit, then instead of prompting the user to provide a breath sample, the system can ask the user to bring the detection unit into contact with the user’s skin. If the detection unit is already in contact with the user’s skin, then the system can simply take the measurement and determine if there is an intoxicant present above a threshold.

[0100] These alternatives for a detection unit and a detection element can be used with each of the systems described herein instead of the breath detection element that is otherwise described.

[0101] In various embodiments, the detection element 105 can include a pump 1038. In various embodiments, a pump 1038 is connected in fluid communication to the detection element 105 by detection element outlet 1043. The pump 1038 is configured to supply a vacuum to the detection element 105 at the opposite end of the sampling port 1041. The pump 1038 is configured to extract the desired sample volume of the breath sample from the breath path 114 and pull it through the detection element 105.

[0102] The pump 1038 can be any suitable type of pump such as a bellows-type pump, or the like. The pump 1038 is used to selectively withdraw a test sample through the detection element 105. In some embodiments, the pump 1038 is able to selectively provide either a vacuum or a positive pressure through the detection element outlet 1043. To withdraw a test sample through the detection element 105 as described above, a vacuum is applied through the detection element outlet 1043. In order to assure no migration of the initial portion of a blow into the detection element 105, the pump 1038 can be configured to provide a slight positive pressure through the detection element outlet 1043 prior to pulling a breath sample into the detection element 105.

[0103] Detection element 105 may further include a heater (not pictured) configured to heat the detection element 105 to a proper operating temperature. The heater may also include a temperature sensing mechanism. Preferably the temperature of the detection element 105 is maintained at 34° C. to keep it above the sample temperature and to prevent condensation of water or vapors. The accuracy of the conversion process is also aided by maintaining a known temperature because the fuel cell catalytic process is temperature dependent.

[0104] Similar to the embodiment of FIG. 3, the substance tester device can include a first tester port 310 and a second tester port 312. In the example of FIG. 10, the second tester port 312 coincides with the breath path outlet 1035. In such an embodiment, during a calibration procedure, a portion of the calibration standard fluid is provided to the detection element 105 through the breath path 114.

[0105] In a more detailed embodiment, when the substance tester device 100 is docked to the calibration station 202 and upon receiving a calibration initiation signal from the tester controller, the calibration station 202 is configured to provide a portion of the calibration standard fluid to the detection element 105 of the substance tester device 100 via the second calibration station port 520 and the second tester port 312. The calibration station 202 can be further configured to trigger the pump 1038 to draw the calibration standard fluid up through the breath path 114 and into the detection element 105.

[0106] In various embodiments, after providing a portion of calibration standard fluid to the detection element 105, the substance tester device 100 is configured to measure a substance concentration value of the calibration standard fluid with the detection element. The substance tester device 100 can then compare the measured substance concentration value to a specified expected reference substance concentration of the calibration standard fluid.

[0107] Referring now to FIG. 11, a schematic view of a portion of a substance tester device is shown in accordance with various embodiments herein. Similar to the embodiment of FIG. 4, the substance tester device can include a first tester port 310 and a second tester port 312. In the example of FIG. 11, the second tester port 312 is in fluid communication with a calibration channel 1142, which is in fluid communication with the sampling port 1041 of the detection element 105 via the breath path 114. In such an embodiment, during a calibration procedure, the portion of the calibration standard fluid is provided to the detection element through a calibration channel 1142 that is in fluid communication with the breath path.

[0108] In a more detailed embodiment, when the substance tester device 100 is docked to the calibration station 202 and upon receiving a calibration initiation signal from the tester controller, the calibration station 202 is configured to provide a portion of the calibration standard fluid to the detection element 105 of the substance tester device 100 via the second calibration station port 520 and the second tester port 312. The calibration station 202 can be further configured to trigger the pump 1038 to draw the calibration standard fluid up through the calibration channel 1142. The calibration standard fluid is then drawn into the breath path 114 and finally into the detection element 105 via the sampling port 1041. Compared to FIG. 10, the embodiment of FIG. 11 delivers the calibration standard fluid closer to the detection element.

[0109] Referring now to FIG. 12, a schematic view of a portion of a substance tester device is shown in accordance with various embodiments herein. Similar to the embodiment of FIG. 4, the substance tester device can include a first tester port 310 and a second tester port 312. In the example of FIG. 12, the second tester port 312 is in fluid communication with a calibration channel 1142, which is in fluid communication with the detection element 105. In such an embodiment, during a calibration procedure, the portion of the calibration standard fluid is provided to the detection element through a calibration channel 1142 and directly into the detection element 105.

[0110] In a more detailed embodiment, when the substance tester device 100 is docked to the calibration station 202 and upon receiving a calibration initiation signal from the tester controller, the calibration station 202 is configured to provide a portion of the calibration standard fluid to the detection element 105 of the substance tester device 100 via the second calibration station port 520 and the second tester port 312. The calibration station 202 can be further configured to trigger the pump 1038 to draw the calibration standard fluid up through the calibration channel 1142 and into the detection element. In such a configuration, the detection element 105 may include an additional sampling port 1045 to accommodate the delivery of calibration standard fluid via the calibration channel 1142. Compared to FIGS. 10 and 11, the embodiment of FIG. 12 delivers the calibration standard fluid directly to the interior of the detection element rather than to the breath path.

[0111] Mobile Device Connectivity (FIG. 13)

[0112] Referring now to FIG. 13, a schematic view of a calibration station in wireless communication with a mobile device is shown in accordance with various embodiments herein.

[0125] Many different methods are contemplated herein, including, but not limited to, methods of making, methods of using, and the like. Aspects of system / device operation described elsewhere herein can be performed as operations of one or more methods in accordance with various embodiments herein.

[0129] In various embodiments, the tester controller is configured to determine whether the detection element 105 requires calibration. Upon determining that the detection element 105 requires calibration, the tester controller is configured to send the calibration initiation signal to the calibration station 202. In various embodiments, the calibration initiation signal is sent by the tester controller when any suitable criterion or criteria are met.

[0130] In various embodiments, the calibration initiation signal is sent by the tester controller when a predetermined amount of time has been reached since a previous calibration. The predetermined amount of time can be any suitable duration such as one week, two weeks, one month, three months or the like.

[0131] In various embodiments, the calibration initiation signal is sent by the tester controller when a predetermined number of testing procedures have been carried out by the substance tester device 100 since a previous calibration. A testing procedure as defined herein, is an occurrence of the detection element 105 measuring a substance concentration of a sample (e.g., a breath sample provided by a user).

In some embodiments, the calibration station 202 is not configured to cause the fluid interface 828 to open such that the calibration standard flows to the detection element 105 via the second tester port 312 unless the calibration station receives the calibration initiation signal from the substance tester device 100. In some embodiments, the calibration station 202 cannot calibrate the detection element 105 of the substance tester device 100 without receiving the calibration initiation signal from the tester controller. The use of the substance tester device 100 to initiate the calibration process allows for the calibration station to be made with fewer components and at a lower cost. In alternate configurations, the calibration station 202 can contain the functionality to initiate a calibration procedure.

[0136] In various embodiments, the method 1400 can include the step 1406 of calibrating a detection element of the substance tester device.

In various embodiments, after providing a portion of calibration standard fluid to the detection element 105, the substance tester device 100 is configured to measure a measured substance concentration value of the calibration standard fluid with the detection element. The calibration system 200 can then compare the measured substance concentration value to the specified expected reference substance concentration. The calibration system 200 can then record comparison data and in some embodiments, can transmit the data to an external device such as the mobile device 1344, a remote server or the like. In some embodiments, if the measured substance concentration value matches the reference substance concentration, the calibration system does not calibrate the detection. In some embodiments, if the measured substance concentration value does not match the reference substance concentration, the calibration system can calibrate the detection element to set the measured substance concentration to match the reference substance concentration. In some embodiments, if the measured substance concentration value is above or below the reference substance concentration, by more than a threshold amount, the calibration system can issue an error state.

[0138] In various embodiments, the calibration station is configured to transmit an alert to an external device indicating that the detection element is being calibrated during a calibration process. In various embodiments, the calibration station is configured to transmit an alert to an external device indicating that the calibration of the detection element is complete.

FIG. 15 illustrates only one particular example of computing device 1500, and other computing devices 1500 may be used in other embodiments. Although computing device 1500 is shown as a standalone computing device, computing device 1500 may be any component or system that includes one or more processors or another suitable computing environment for executing software instructions in other examples and need not include all the elements shown here.

Storage device 1512, in some examples, is known as a computer-readable storage medium. In some examples, storage device 1512 comprises temporary memory, meaning that a primary purpose of storage device 1512 is not long-term storage. Storage device 1512 in some examples includes a volatile memory, meaning that storage device 1512 does not maintain stored contents when computing device 1500 is turned off. In other examples, data is loaded from storage device 1512 into memory 1504 during operation. Examples of volatile memories include random access memories (RAM), dynamic random-access memories (DRAM), static random-access memories (SRAM), and other forms of volatile memories known in the art.
