Abstract:
A digitally accessible sensor (DAS) assembly includes a sensor, such as a gas sensor, attached to a printed circuit board which includes an analog-to-digital converter, and a digital interface. This modular design significantly shortens the analog signal path from the sensor and provides digital information to the instrument microcontroller, and thereby reduces noise levels from the sensor and circuitry. The circuit board design also includes a non-volatile memory unit allowing retention of information related to the sensor and its operation and/or the application, and may include an amplifier for amplifying the low level analog signal.

Abstract:
The remote starter includes a receiver for receiving wireless signals and a controller coupled to the receiver and the engine ignition. The controller activates the ignition in response to receipt of an engine start signal by the receiver and terminates the operation of the engine upon detection of a predetermined condition. The remote engine starter of the present invention may be used to start a vehicle engine and environmentally condition the vehicle interior without indefinitely operating the vehicle. Preferably, the controller terminates engine operation after a predetermined time. The predetermined time period is preferably selected by a user through a remote transmitter. In response to the time period selection, the controller generates a confirmation signal which indicates the selected time period. The preferred embodiment also includes a brake pedal sensor which generates a signal indicative of depression of the brake pedal and a hood open sensor for generating a signal indicative of an opening of the hood. In response to signal from these sensors, the controller terminates engine operation, if the engine is running, or does not start the engine if a start engine signal is received while either of these conditions is indicated.
A passive arming vehicle alarm system has a valet mode which is activated or deactivated by wireless remote control, thus avoiding the need for hiding a valet switch in the vehicle and subjecting the vehicle to attack at the valet switch. The wireless remote control is also used deactivate the alarm when the alarm is sounding, by depressing any of the buttons on the wireless remote control, regardless of the primary function of the button. As a result, the alarm may be quickly deactivated. The alarm also features progressive passive arming; the alarm emits a brief signal such as a siren chirp as a warning, prior to passively self-arming. As a result, the owner/operator will be warned that the vehicle is about to passively arm and may prevent passive arming (e. g. , by opening a door) if it is undesired. Progressive passive arming begins whenever the alarm is disarmed, so that if the alarm is disarmed but the owner is subsequently distracted, the alarm will automatically re-arm and the vehicle will not be left unprotected.
