摘要:
An apparatus and method of determining bearing and distance measurements between a mobile device and an object using Rf based measurements. The mobile device communicates with a control in the object to determine the relative bearing between the mobile device and the object with respect to magnetic north and, optionally, the distance between the mobile device and the object. An indicator on the mobile device aid in directing s the user of the mobile device toward the object as the mobile device is moved relative to the object. The mobile device can be a key fob and the object can be a vehicle.

Long-range remote communication and control of a vehicle is achieved with primary and secondary cellular devices provided by the vehicle user. The primary cellular device is retained by the user, while the secondary cellular device is dedicated to the vehicle and placed in a docking station provided in a vehicle instrument panel or console. The vehicle docking station is equipped with typical cell phone electrical interfaces to supply battery charging current and to establish a bi-directional data communication link between the secondary cellular device and an on-board vehicle computer. The secondary cellular device remains activated, and provides a low-cost remotely accessible communication link between the on-board vehicle computer and the primary cellular device or any other phone, provided that specified security conditions are satisfied.

A method of locating a parked vehicle that is equipped with a RKE system including a vehicle-installed RF communication module and a driver-borne wireless RF nomadic device such as a key fob involves installing a RFID tag in the nomadic device and a RFID interrogator in the vehicle. The driver depresses a button on the nomadic device to transmit a location request to the vehicle's communication module, and the RFID interrogator in turn emits a RF interrogation signal to identify the RFID tag and determine its location relative to the vehicle. The communication module then transmits a compass bearing to the nomadic device, and an indicator of the nomadic device is activated to provide the driver with a bearing for locating the vehicle.

A self-powered wireless fuse switch is disclosed that is a plug-in replacement for a fuse found in the electrical system of vehicles. The self-powered wireless fuse adds remote-controlled switching capabilities for short and long-range control of power to subsystems of a vehicle electrical system. The wireless fuse switch includes an internal transceiver that receives commands from a remote control unit and controls the position of an internal relay. The wireless control module interfaces with a fuse socket of the vehicle to selectively allow or interrupt power from the vehicle to the subsystem of the vehicle electrical system. The wireless fuse switch includes either a two-blade or three-blade harness assembly that allows the wireless fuse switch to be received within the fuse socket of the vehicle.

A drive system for powering LED triads includes a controller for supplying power to one or more LED triad modules with integral encoding of the desired hue and intensity information. The LED triad modules each include an LED triad and decoding circuitry for activating the individual LED elements of the triad according to the encoded hue and intensity information. In the illustrated configuration, the controller supplies power to the LED triad modules over a pair of conductors, and the supplied power is modulated using a four-phase encoding sequence that is decoded by the decoding circuitry of each LED triad module so that each LED triad module produces light of the desired hue and intensity.
