Abstract: A self-powered sensor detects or measures an event by converting one form of energy into another form. The converted energy may be conditioned and regulated to drive a wireless transmitter and encoder. A receiver may detect and validate a received message. If validated, the message may be processed or decrypted and processed to determine what has been identified or requested.

Abstract: A personal information management system stores associations between a user and the user's mobile hand held electronic and communication devices. The system receives input indicating the presence of the user and bonds with the mobile hand held devices associated with the identified user to the exclusion of other devices. Once the system has bonded to the user's mobile hand held devices, the user may access data stored on and control functions of the various hand held devices through a single common interface, the system may be used to place and receive cellular telephone calls, send and receive text messages, and record and play back audio messages.

Abstract: A vehicle window control system is configured to move a window to a selected position or until a desired change in position has been achieved. The system includes an input device and a control device. The input device generates a signal indicative of a desired window movement. The switch analyzes the received input signal to detect an input mode, and generates an output signal that causes a window to move in accordance with the received signal data.

Abstract: A remote keyless entry (RKE) system performs multiple functions in a vehicle. One function is to respond to RKE controller keypresses to lock or unlock doors, to start an engine, or to arm or deactivate an alarm. A second function is to interpret RKE controller keypresses as accessory control commands. The RKE controller thereby provides a convenient accessory controller. In addition, the RKE controller may also supplement or take the place of pre-existing dedicated accessory controllers, such as controllers for a radio, video game, or DVD player, to relieve the burden of locating and operating those accessory controllers.

Abstract: A crystal-less keyless entry system includes a micro controller, a timing circuit, a memory, and a radio frequency circuit. The memory and timing circuit are a unitary part of the microprocessor. The memory is programmed with a compensation that adjusts an output frequency of the timing circuit such that the output frequency of the timing circuit does not coincide with a frequency discontinuity that occurs within an output of the timing circuit. A method of calibrating the crystal-less keyless entry system includes programming the temperature compensation and a voltage compensation in the memory.

Abstract: A method of calibrating a remote keyless entry system adjusts a timing circuit that is a unitary part of a microprocessor. The method drives a plurality of inputs to the microprocessor to a logic state, monitors the output of the microprocessor, and programs a calibration factor within the microprocessor based on the output of the microprocessor. The calibration factor controls an output frequency of the timing circuit.
