    Abstract: A tire monitor for monitoring a characteristic of tires on a vehicle includes a circuit configured to receive a first wireless signal having tire characteristic data and a first wireless protocol. The circuit is further configured to receive a second wireless signal having tire characteristic data and a second wireless protocol. The second wireless protocol is different than the first wireless protocol. The circuit is configured to monitor first tire data on the first wireless signal and second tire data on the second wireless signal.

    Abstract: A tire pressure monitoring system identifies tire locations by recognizing that certain characteristics are unique to front-located tires verses rear-located tires as well as left-side tires and right-side tires. A control circuit is coupled to a temperature sensor and an accelerometer for each tire to receive information processed to discriminate between left and right and front and rear tires, respectively. With this information and a pressure signal, the monitoring system provides the operator with tire location and pressure information without reprogramming upon tire rotation. The system also alerts the operator to run-flat tire operational constraints.

    Abstract: An electronic vehicle accessory includes a non-volatile memory, and a controller coupled to the non-volatile memory and to a speed sensor of the vehicle for receiving speed data representing the vehicle's current speed. The controller determines when the vehicle's current speed falls below a predetermined threshold and stores variable data in the non-volatile memory when the vehicle's speed is below the predetermined threshold. The electronic vehicle accessory may be an instrument panel, an electronic compass, and/or a mini-trip computer, which may be housed in an overhead housing. By storing variable data in the non-volatile memory as a function of the vehicle's speed, the present invention ensures that the most up-to-date data is stored in the non-volatile memory before the vehicle's ignition is turned off while eliminating excessive stores that shorten the lifetime of the non-volatile memory. Further, by storing data as a function of vehicle speed, the connection to a battery powerline may be eliminated and the manufacturing and installation costs may be significantly reduced. Additionally, excessive battery drain resulting from the electronic accessory being locked in a failure mode may be prevented.

    Abstract: A visor or other vehicle housing of the present invention RF couples signals from a remote RF garage door opening transmitter located in a visor, for example, to a 1/4 wave passive antenna, which in the preferred embodiment includes a thin foil strip extending along the longitudinal length of the visor. Such an antenna thereby creates an improved radiation pattern having improved radiation strength in the forward facing direction of the vehicle.
