A controller for triggering a pyrotechnic component of a vehicle is designed to determine and store a trigger status of the pyrotechnic component. The trigger status exhibits a triggered state or a non-triggered state. The controller is further designed, if the trigger status exhibits the non-triggered state, to allow operation of the controller with a pyrotechnic component in the vehicle without enabling the pyrotechnic component. Further, the controller is designed, if the trigger status exhibits the triggered state, to reset the trigger status from the triggered state to the non-triggered state when the pyrotechnic component is enabled.

An electronic module assembly (EMA) for use in controlling one or more personal restraint systems. A programmed processor within the EMA is configured to determine when a personal restraint system associated with each seat in a vehicle should be deployed. In addition, the programmed processor is configured to perform a diagnostic self-test to determine if the EMA and the personal restraint systems are operational. In one embodiment, results of the diagnostic self-test routine are displayed on a display included on the electronic module assembly. In an alternative embodiment, the results of the diagnostic self-test routine are transmitted via a wireless transceiver to a remote device. The remote device can include a wireless interrogator or can be a remote computer system such as a cabin management computer system.

A deployment circuit for a pyrotechnic device is provided. An example deployment circuit comprises a driver circuit, a monitoring circuit and a control circuit. The driver circuit energizes the pyrotechnic device by applying a voltage or current to a first terminal and second terminal. The monitoring circuit measures a voltage across the first terminal and second terminal, processes the measured voltage, and determines whether the processed voltage is greater than a threshold. In response to a processed voltage above the threshold, the monitoring circuit asserts a comparison signal. The control circuit receives a fire request signal and the comparison signal. In response to the fire request signal, the control circuit generates a control signal to energize the pyrotechnic device via the driver circuit and determines whether the comparison signal is asserted. In response to determining the comparison signal is de-asserted, the control circuit energizes again the pyrotechnic device.

A screen capture tool includes a set of programmatic instructions, a main body, a system controller, a pair of communication cables, and a remote-control unit. The first communication cable includes a USB cable that receives power from an automotive diagnostic scope and sends digital information to the scope. The second communication cable includes a coaxial cable that sends analog or digital information to the diagnostic channel input of the scope. When the scope is connected to a vehicle, the scope displays continuous real time diagnostic information about the vehicle on the display screen of the scope as the vehicle is being driven. The remote button is depressed upon encountering a malfunction of the vehicle to freeze the image on the display and to display a marker indicating the time the error was detected.

A control circuit includes (i) at least one voltage output end, each said voltage output end being connected to a filter capacitor, (ii) at least one detection circuit disposed in the control circuit, each said detection circuit being connected to one said voltage output end, and (iii) a fault output apparatus which is configured to, when the detection circuit detects that a fault has occurred in the filter capacitor connected to the voltage output end, output corresponding filter capacitor fault indication information. The power supply output apparatus has no need for a redundant capacitor design, and can determine whether a fault has occurred in the filter capacitor on the basis of the duration of charging of the filter capacitor thus ensuring the reliability and stability of the power supply output apparatus.

A control circuit includes: a current detection unit, where the current detection unit is configured to: when being connected to a battery, output a first type signal when detecting that the battery has an overcurrent or a short circuit; and a driver circuit, where an input terminal of the driver circuit is connected to a signal output terminal of the current detection unit, an output terminal of the driver circuit is configured to connect to a safety module in the target loop, and the driver circuit is configured to output, in response to receiving the first type signal transmitted from the current detection unit, a drive signal to drive the safety module to be disconnected, where the target loop is a loop in the battery or a loop in a device in which the battery is located.

A vehicle safety device test system includes a vehicle, a first safety device, an electronic controller, a breakout box, and a data acquisition system. The first safety device is disposed in the vehicle. The electronic controller is disposed in the vehicle. The electronic controller is electrically connected to the first safety device. The breakout box is disposed in the vehicle. The breakout box is electrically connected to the electronic controller. The data acquisition system is disposed in the vehicle. The data acquisition system is electrically connected to the breakout box.
