A remote convenience system ( ) and an associated function remotely control convenience functions at a vehicle ( ). A receiver/controller ( ), located at the vehicle ( ), receives vehicle remote convenience function request signals ( ) that convey remote function request messages and controls vehicle systems (e.g., , and ) to perform the remotely requested vehicle functions. The receiver/controller ( ) includes a messaging processing portion ( ) for providing a signal (e.g., ) to activate an at-vehicle alarm component (e.g., ) and for providing a signal ( ) to activate a remote assistance-summoning component ( ). A portable transmitter outputs the remote convenience function request signals ( ) to cause remote control performance. The transmitter ( ) includes a manually actuatable emergency pushbutton switch ( ). The switch ( ) is actuatable in a first operation mode (e.g., a single actuation) to cause activation of the at-vehicle alarm component ( ), and is actuatable in a second, different operation mode (e.g., a plurality of actuations) to cause activation of the remote assistance-summoning component ( ).

System and method for remote convenience function control with at-vehicle and remote assistance-summoning functions

A tire condition communication system ( ) for a vehicle ( ) that has a tire (e.g., A). A sensor (e.g., ), associated with the tire (e.g., A), senses at least one tire condition. A memory (e.g., ), associated with the tire (e.g., A), holds an identification. Transmitter components (e.g., and ), associated with the tire (e.g., A) and operatively connected to the sensor ( ) and the memory ( ), transmit a condition signal (e.g., A) that indicates the held identification and the sensed tire condition. A vehicle-based unit ( ) receives the transmitted condition signal (e.g., A) indicative of the held identification and the sensed tire condition. An identification provision unit (e.g., A), located on the vehicle ( ) adjacent to the tire (e.g., A) and having a location identification, transmits the location identification in response to a request. A communication portion (e.g., A) of the tire condition sensor unit (e.g., A) communicates a request to the identification provision unit (e.g., A) to transmit the location identification. The tire condition sensor unit (e.g., A) receives the requested location identification and updates the held identification.

Tire condition sensor communication with tire location provided via vehicle-mounted identification units

A tire condition communication system ( ) and method for a vehicle ( ) that has a tire (e.g., A). A sensor ( ), associated with the tire (e.g., A), senses at least one tire condition. A memory ( ), associated with the tire (e.g., A), holds an identification. A transmitter arrangement ( and ), associated with the tire (e.g., A), transmits a signal (e.g., A) that indicates the held identification and the sensed tire condition. A receiver arrangement ( and ), associated with the vehicle ( ), receives the transmitted signal (e.g., A). An identification update device is associated with the tire and is operatively connected to the memory ( ). The update device receives an update identification and provides the received location identification to the memory ( ) to be held as the held identification. An input device is manually actuated to provide the update identification. In one example, a receiver ( ) at the tire and a manually actuated transmitter ( ) provided the update and input devices. In another example, a switch ( ) and a manually actuatable part (e.g., a valve stem part) at the tire provide the update and input devices.

An active load applied to the gate transmission line termination of distributed power devices reduces the low frequency noise power appearing at the output of the device. The active load, including at least one active device such as a field effect transistor, operates by transforming the input impedance of a low noise amplifier to the desired load impedance. The active load is connected to one end of an input transmission line having a plurality of impedances connected in electrical series. An input terminal is connected to the opposite end. An output transmission line, also having a plurality of impedances connected in series, has an output terminal at one end and a terminating output impedance at the other. A plurality of active devices are connected to junction points between the series connected impedances of the input and output lines.
