Abstract:
A wireless control system for use in a vehicle and for use with a remote electronic system is provided. The wireless control system includes a transceiver for mounting in the vehicle. The transceiver is configured to communicate according to a Bluetooth communications standard. The transceiver is further configured to provide a control signal to the remote electronic system. The transceiver is also trainable to provide a carrier frequency and control information for the control signal.
Abstract:
A wireless communications system and method adapted for use in automotive applications for enabling automatic, high-speed, wireless voice and/or data communications link to be established between a wide variety of external devices and various electronic subsystems of a vehicle. The apparatus includes first and second RF transceivers which are operated in accordance with a communications specification to enable a seamless, automatic communications link to be created when the two RF transceivers come within a pre-determined proximity of one another, for example, within up to 100 meters of one another. Information from one device is then automatically transmitted over the wireless communications link to the other device. In various implementations the apparatus is used to obtain information from a home PC, a work PC, a notebook PC and various other electronic devices, as well as information from the Internet, which is displayed and/or played back for the user by various subsystems of the vehicle while traveling in the vehicle. Other applications involving retail and manufacturing applications are disclosed by which the apparatus is used to facilitate and/or expedite manufacturing processes or retail transactions via one or more high-speed, secure, wireless communications links which are created automatically and seamlessly between the RF transceivers of the apparatus of the invention.
Abstract:
A trainable transceiver for learning and transmitting an activation signal that includes an RF carrier frequency modulated with a code for remotely actuating a device, such as a garage door opener. In one embodiment, the trainable transceiver preferably includes a controller, a signal generator, and a dynamically tunable antenna having a variable impedance that may be selectively controlled in accordance with a carrier frequency of a received or transmitted activation signal. In another embodiment, the trainable transceiver preferably includes a phase-locked loop circuit for providing a frequency control voltage to a signal generator to selectively adjust the carrier frequency of the signal generator. In yet another embodiment, the trainable transceiver includes an amplifying circuit for selectively controlling the gain of a modulated radio frequency carrier signal received from the signal generator and for transmitting an amplified output signal to the remotely actuated device. In a further embodiment, the trainable transceiver includes a frequency table including a list of frequencies for remote transmitters known to transmit for only a short duration and the trainable transceiver first reads the short duration frequencies from the frequency table. Some embodiments will include one or more of these various features.

Abstract:
A wireless mesh network where a portion of the nodes have reduced receive sensitivity. The negative effects of the density of the wireless mesh network, such as interference, are reduced when fewer nodes receive messages to rebroadcast. In an alternative embodiment, some of the nodes of the mesh network are configured to not rebroadcast even if they receive a message. A method for configuring a dense mesh network is also provided. As many nodes as possible are discovered and registered in the network. Node characteristics of those nodes are adjusted to reduce or eliminate the negative effects of the dense mesh network so that additional nodes may be discovered and registered.

A method includes providing a first data collection unit and a second data collection unit, each of the first test data collection unit and the second data collection unit comprising a wireless transceiver and adapted for wireless communication therebetween, physically moving the first data collection unit to each of a plurality of different locations within the use environment associated with use of the home appliance, establishing a radio frequency link between the first data collection unit and the second data collection unit at each of the plurality of different locations within the use environment, characterizing quality of the radio frequency link at each of the plurality of different locations, the quality of the radio frequency link being at least partially based on the path loss within the use environment, and determining an aggregate characterization of the first data collection unit within the use environment using the quality of the radio frequency link at each of the plurality of different locations. A system for characterizing radio communications quality is also provided.
Abstract:
An electronic system that includes a trailer sensor, a lock sensor and a control circuit determine whether a trailer hitch assembly is properly coupled to a trailer. The trailer sensor senses the position of the trailer relative to the trailer hitch assembly and the lock sensor senses the position of the locking mechanism. The control circuit is coupled to the trailer sensor and the lock sensor and masks an output of the lock sensor for a first predetermined stabilization period after the control circuit initially determines that the trailer hitch assembly is properly coupled to the trailer.
