Universal garage door opener and appliance control system operable to facilitate garage door opener and appliance control with a fob or other wireless device operable to wirelessly communicate corresponding instructions to a vehicle other device for subsequent relay to the garage door opener or controlled appliance.
摘要:
A vehicle system includes a body control module for controlling at least one body control system. The body control module has a microcontroller. A garage door opener module is adapted to be mounted within a vehicle. The garage door module provides an actuating signal for a garage door opener. A keypad is adapted to be mounted on the vehicle and accessible from outside of the vehicle. The keypad provides input to the microcontroller for controlling the garage door opener module.
摘要:
A control module may be configured to support wireless transmission and/or receipt of signals used to direct universal garage door openers and other appliance control systems. The control module may be operable to prevent certain garage door opener and/or application control requests in the event certain security measures are not met. The control module may be integrated into a smart junction box, body control module, and/or other module in the event the control module is adapted for use within a vehicle.

摘要:
Vehicle information (e.g., status information, calibratable parameters, or diagnostic data) is transmitted from a base station mounted in a vehicle to a portable RKE fob via a radio-frequency signal within a specified average field strength limit. A multi-byte vehicle message is formed and then coded into a multi-bit coded message. The multi-bit coded message is framed into a plurality of packets. The radio-frequency signal is wirelessly transmitted from the base station with a plurality of spaced packet windows having a predetermined duty cycle, each packet window including a respective one of the plurality of packets. The radio-frequency signal within each of the packet windows has a predetermined field strength greater than the average field strength limit and a substantially zero field strength between the packet windows. The predetermined duty cycle results in an actual average field strength for transmitting all of the packets not exceeding the average field strength limit.

A vehicle tire pressure monitoring (TPM) system, the system including an immobilizer transmitter that transmits at least one low frequency (LF) sensor diagnostic signal, at least one TPM sensor, wherein the at least one TPM sensor includes a transceiver that receives the at least one LF sensor diagnostic signal and, when the at least one TPM sensor is operating properly, presents at least one radio frequency (RF) message signal, and a TPM receiver that receives the at least one RF message signal and provides an indication to an operator when the at least one RF message signal is received, wherein the LF sensor diagnostic signal is transmitted to determine proper operation of the at least one TPM sensor.
摘要:
An antenna system for a tire pressure monitoring radio frequency (RF) electronic device that includes a printed circuit board (PCB), a ground plane, and an active element. The PCB has a top surface and a bottom surface. The ground plane is on the bottom surface. The active element is mounted on the top surface. The active element includes a first segment positioned in a top surface plane and connected to a second segment oriented at an angle to the top surface.
