Publication number: 20130013149Abstract: A status of one or more subsystems positioned on one or more trailers is communicated to a tractor electrically and mechanically connected to the trailer. A spread spectrum data communications signal representing the status of a respective subsystem is superposed on the power bus. The status of the respective subsystem can then be determined from the spread spectrum data communications signal. Preferably, the status of the subsystem is indicated to an operator positioned on the tractor. A command for controlling a subsystem on a trailer can also be communicated from the tractor to the trailer over the power bus. A spread spectrum data communications signal representing the command is produced on the power bus, and the subsystem is controlled based on the spread spectrum data communications signal. Preferably, the command is received from an operator positioned in the tractor.Type: ApplicationFiled: August 27, 2012Publication date: January 10, 2013Applicant: POWER TALK, INC.Inventors: Alan Lesesky, Bobby Ray Weant

Patent number: 8276996Abstract: A status of one or more subsystems positioned on one or more trailers is communicated to a tractor electrically and mechanically connected to the trailer. The status may be automatically supplied by the subsystem or may be requested either by the operator of the tractor/trailer combination or automatically by another subsystem on either the tractor or the trailer. A spread spectrum data communications signal representing the status of a respective subsystem is superposed on the power bus. The status of the respective subsystem can then be determined from the spread spectrum data communications signal. Preferably, the status of the subsystem is indicated to an operator positioned on the tractor. A command for controlling a subsystem on a trailer can also be communicated from the tractor to the trailer over the power bus. A spread spectrum data communications signal representing the command is produced on the power bus, and the subsystem is controlled based on the spread spectrum data communications signal.Type: GrantFiled: May 16, 2011Date of Patent: October 2, 2012Assignee: Power Talk, Inc.Inventors: Alan Lesesky, Bobby Ray Weant

Patent number: 7280898Abstract: An apparatus and methods are provided for data communications associated with a vehicle. The apparatus preferably includes at least one electronic subsystem associated with the vehicle and a plurality of electrical conductors connected to the at least one electronic subsystem and associated with the vehicle. A vehicle data communications protocol converter is preferably connected to the plurality of electrical conductors for converting a first data communications protocol associated with data communications along the plurality of electrical conductors to a second data communications protocol such as a local-area infrared or an RF data communications protocol. The apparatus also preferably includes a transceiver connected to the data communications protocol converter for transmitting the second data communications protocol from the vehicle and receiving the data communications protocol from a remote data communications terminal or another portion of the vehicle.Type: GrantFiled: December 18, 2003Date of Patent: October 9, 2007Assignee: Power Talk, Inc.Inventors: Alan C.

Patent number: 6604038Abstract: The present invention provides several apparatus, methods, and computer program products for establishing a data communication link between an interrogation device and the data bus of a vehicle. Specifically, in one embodiment, the present invention provides apparatus, methods, and computer program products that process data transmitted to and from the data bus of a vehicle one bit at a time with minimal delay. The apparatus, methods, and computer program products of this embodiment also prevent propagation of false data to both the data bus and the interrogation device, which is generated by the transmission of data to and from the data bus. The present invention also provides apparatus and methods that reduce the introduction of false data in the form of signal noise onto the data bus of a vehicle when the data bus is not transmitting data to or receiving data from a remote location.Type: GrantFiled: November 9, 1999Date of Patent: August 5, 2003Assignee: Power Talk, Inc.Inventors: Alan C.
