Abstract: A tire pressure monitoring system includes a receiver for processing signals and alerting an operator of the vehicle should conditions within any of the tires fall outside a desired range. The transmitters within the tires emit shorter transmission signals during operation by eliminating transmission of the identification code. The receiver stores the identifier for each transmitter for comparison to subsequent transmissions. Subsequent transmissions do not include the identifier. The receiver combines the saved identifier with the value provided in the check portion of the incoming transmission. If the combination of the saved identifier with the value provided in the check portion meets a defined criteria, than the signal is recognized as originating from one of the transmitters.

Abstract: A method of monitoring a battery energy management system includes discharging a detector circuit to a minimum battery voltage, measuring an elapsed time that the minimum battery voltage is detected, resetting a timer circuit, and sampling the minimum battery voltage and the elapsed time of the minimum battery voltage in response to a predefined prompt. The discharge of the detector circuit, the measurement of the minimum battery voltage, the elapsed time of the minimum battery voltage, and the reset of the timer circuit are performed in response to an input voltage being less than the voltage stored within the detector circuit.

Abstract: A keyless ignition system for a vehicle includes an electronic control unit (ECU) that communicates through a wireless link with a start/stop button. The start/stop button includes a plurality of lighting sources to selectively illuminate the start/stop button for communicating current state of a vehicle operating parameter. The lighting sources are powered by a wireless power generating device within the start/stop button.

Abstract: A real time clock assembly includes paired crystal oscillators that experience changes in frequency responsive to temperature. The differences in frequency changes between the paired crystal oscillators are utilized to determine a temperature utilized to compensate for those shifts in frequency. The predictability of frequency responsive to temperature variations by the paired crystal oscillators is utilized for the determination of temperature.

Abstract: A method for improving the reception performance of a remote signal communication system includes communicating a signal from a proximate communication device to an electronic control module, communicating a first portion of the signal to a first input capture of the electronic control module, and communicating a second portion of the signal to a second input capture of the electronic control module.

Abstract: An overcurrent detection circuit assembly provides a diagnostic feedback signal indicative of an overcurrent or short condition is disclosed. The detection circuit receives a sense current that is proportional to a load current provided to an electrical device or load. The detection circuit provides the feedback signal to a microcontroller that can control the device and the power supply to protect the device against short circuit or other fault condition.

Abstract: A tire pressure monitoring system includes a process of reconstructing a complete data frame from portions of partially received data frames. The tire pressure monitoring system includes a receiver that includes a buffer to store portions of the transmissions for reconstruction of data in response to portions of the transmission not being received. A reconstructed data frame is generated using the saved partially received data frame and the currently received partial data frame.

Abstract: A method for reducing average current consumption in an RF system adjusts RF stabilization time by measuring the temperature of the operating environment. The RF system includes a RF receiver that has a predetermined base RF receiver stabilization time. A temperature sensor takes at least one temperature measurement of the environment in which the RF receiver operates. The base RF receiver stabilization time is then adjusted based on the temperature measurement.

Abstract: A filter assembly (10) includes a hollow housing (12) having a length and first and second ends (14,16). A membrane (22) contained within and extending along the length of the housing (12) separates the housing (12) into first and second chambers (24,26). An inlet (32) is proximate to the first end (14) and is in fluid communication with the first chamber (24). An outlet (34) is proximate to the second end (16) and is in fluid communication with the second chamber (26) for allowing a flow of fluid from the second chamber (26). The membrane (22) is air permeable when dry and air impermeable when wet whereby a wetting fluid entering the first chamber (24) at the first end of the housing (12) forces air from the first and second chambers (24,26) along the length of the membrane (22) and out of the outlet (34) as the fluid wets the membrane (22) thereby de-airing the first and second chambers (24,26) from one end to the other end along the length of the membrane (22) on both sides thereof.
