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 circuit assemblage for carrying out a comparison between a first signal and a second signal in consideration of a reference signal, the circuit assemblage encompassing: a first channel in which the first signal is processed; and a second channel in which the second signal is processed, a first differential amplifier, which obtains a first difference between the first signal and the reference signal, and a first unit for obtaining an absolute value, which obtains a first absolute value from the first difference, being provided in the first channel, and a second differential amplifier, which obtains a second difference between the second signal and the reference signal, and a second unit for obtaining an absolute value, which obtains a second absolute value from the second difference, being provided in the second channel; and a comparator that compares the first absolute value with the second absolute value.

A grounding system for an automotive protective system inflator is provided for protecting the inflator from inadvertent discharge and operation of the automotive protective system, such as, e.g., an airbag system. The grounding system can include an electrical connector configured to couple the inflator to an electrical harness of a vehicle. The electrical connector can include a ground path and a biased member coupled to a ground wire. The ground wire may be coupled to a ground path of the vehicle so as to draw an inadvertent electrical charge away from the inflator to the vehicle electrical harness.

A vehicle comprises: an airbag; a first power supply configured to supply power; a first sensor configured to sense an impact applied to the vehicle; a first wiring connected to the first power supply and configured to transmit the power while the vehicle is running; a second wiring connected to the first power supply and configured to transmit power regardless of whether or not the vehicle is running; and a controller configured to deploy the airbag upon receiving power via the first wiring or the second wiring when the first sensor senses the impact.

A system includes control modules, a low-voltage communications bus, e.g., a CAN bus of a vehicle, a voltage sensor that measures a bus voltage and outputs 2.5-3.5 VDC high-data and 1.5-2.5 VDC low-data, and a host electronic control unit (ECU). The host ECU detects a recoverable fault using a data pattern in the bus voltage data when the data is outside of a calibrated range, and recalibrates the sensor. Recalibration may be by adjustment to a scaling factor and/or a bias value. Non-recoverable stuck-at-fault-type or out-of-range-type faults may be detected using the pattern, as may be a ground offset fault. A method includes measuring the bus voltage using the sensor, comparing the output data to a range to detect the fault, and isolating a sensor fault as a recoverable fault using the data pattern when the data is outside of the range. The sensor is then be recalibrated.
