20080204217 | ROBUST RADIO FREQUENCY SIGNALS - 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. | 08-28-2008 |
20080205553 | RECONSTRUCTION OF TIRE PRESSURE MONITORING SIGNALS - 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. | 08-28-2008 |
20080225455 | OVERCURRENT DETECTION LATCH CIRCUIT - 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. | 09-18-2008 |
20080266068 | Remote Signal Communication System Having Improved Reception Performance - 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. | 10-30-2008 |
