Abstract: A disclosed example receiver for receiving transmissions and data for both a remote keyless entry (RKE) system and a tire pressure monitoring (TPM) system tailors the data slice level to the characteristics unique to each of the RKE transmissions and the TPM transmissions.

Abstract: An ambient light control module and method of operating an ambient light control module selectively actuates light modules to provide a desired light color and intensity. The disclosed ambient light control module selectively actuates light modules that are controllable to provide desired colors. The light control module produces uniform signals across the several light modules such that each separate light module will emit the same color. The disclosed example light control module includes a microcontroller with a plurality of output channels including output compare channels and pulse width modulated channels. The output channels are matched to a common clock so that a uniform signal is emitted from any channel to provide the desired uniformity between lighting modules.

Abstract: A passive entry and start system transmits a neutral signal over all the antennas except for that antenna that is proximate an area in which transmission to an identification device is desired. Accordingly, the area of a vehicle and those physical features that are proximate and associated with the area is isolated to prevent undesired operation of other vehicle mechanisms.

Abstract: An identification device is user configurable to communicate according to different communication protocols. Once the identification device has been set to a desired communication protocol where all it will immediately transmit an identification code to the corresponding vehicle controller such that the vehicle controller will learn the identification code and be able to recognize subsequent transmissions and authenticate the identification device.

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 method for the power-saving control of a receiving device 1, in particular for an access control system for an automobile, is disclosed wherein in an inquiry mode it is determined in response to a control signal Sa whether a receive signal Sr to be processed is supplied by a receiver unit 7 of the receiving device 1 to a controller 3 of the receiving device 1. The receiver unit 7 and the controller 3 are, in response to the control signal Sa, simultaneously switched from a power-saving sleep mode in each case to an active mode in each case.

Abstract: A remote keyless entry (RKE) circuit (100) and method reduces the amount of current draw by duty cycling the RKE circuit (100) to ensure that a microcontroller (104) in the RKE circuit (100) is awakened only when needed to evaluate RF data. A total operating period for the RKE circuit (100) includes a transient period, a data monitoring period, and a sleep period. The RKE circuit (100) includes a pulse blocking circuit (109) that prevents a receiver stabilization pulse from waking up the microcontroller (104). If no data is received during the data monitoring period, the microcontroller (104) remains in a sleep mode for the remainder of the operating period.

Abstract: A remote memory preference system for a passenger vehicle is disclosed. The remote memory preference system utilizes existing passive or active remote entry devices. Memory preference settings include driver's seat position, mirror positions and radio station presets. Once these settings are adjusted by a primary vehicle user, they are stored in a memory location in the vehicle either automatically or when a memory button on the remote entry device is depressed by the user. Settings may then be later recalled either automatically by activating the remote entry device or when a recall button on the remote entry device is depressed by the user. The system may also employ a shift register system, which would automatically store current and previous memory preference settings.
