A circuit for interfacing with a sensor having a sensor input current and a modulated sensor current signal corresponding to a sensed condition. A control module is coupled to the sensor and receives the sensor current signal. The control module converts the sensor current signal to a modulated signal having a pulse width with a duration corresponding to the sensed condition. The control module counts a time corresponding to the pulse width. The time corresponds to the sensed condition.

Modulated interface for remote signals

A sensor system for detecting impacts to a vehicle, including diagnostics for monitoring the sensor system. The sensor system includes one or more piezoelectric sensor assemblies (,), each including a coaxial piezoelectric cable (,) contained within a tube housing (,), which is mounted to a structural member of the vehicle. The sensor system may also include accelerometers (,) that are also in communication with the restraints control module (,) and employed in combination with one or more piezoelectric sensor assemblies (,). Further, the sensor system includes diagnostics for monitoring one or more of the sensor assemblies (,) in order to detect a sensor failure, while not interfering with the impact signals from the sensor assemblies (,).

Diagnostics for vehicle deformation sensor system

A method and system for detecting degraded operation of a solenoid. A current through the solenoid is sampled at predetermined time intervals within a predetermined time period. A maximum value of the sampled current is first detected. Next, a minimum value of the sampled current subsequent to the maximum value is detected. Finally, a predetermined increase in the sampled current from the minimum value is detected to verify operation of the solenoid.

Method and system for verifying solenoid operation

An acoustic production system having multiple signal sources and a power amplifier driving an acoustic transducer such as a loudspeaker includes an arbitrator in a power limiter circuit to selectively limit the input level of one of the sources to the power amp in response to an overdrive signal from the amplifier. The input level to the power amplifier is automatically reduced in response to the overdrive signal until a predetermined level of limiting has been attained. Once the predetermined level of limiting is reached, the arbitrator outputs a second overdrive signal to prompt additional limiting of the power amplifier output. Preferably, the arbitrator is included in an interior active noise cancellation module combined with an audio entertainment system for a passenger compartment of a motor vehicle. The audio system also preferably separates the audio reproduction into high frequency and low frequency branches, whereby the arbitrator acts upon the signals output in the frequency ranges of active noise cancellation and the bass output of the audio entertainment system that are most likely to overdrive an amplifier.
