Patent number: 5257290Abstract: A system for digital communication over a wire lain along the path of guided vehicles to a modem and a loop driver, the modem providing high frequency signals and the loop driver providing low frequency control signals. Instead, the modem and the loop driver are connected to one end of the wire and the other end of the wire is connected through an impedance matching network to earth ground. The impedance matching network provides an impedance approximately equal to the impedance of the wire at the frequency of the high frequency signals. The impedance matching network may conveniently comprise an inductor (choke) in parallel with a capacitor connected between the end of the wire and earth ground and a plurality of resistors connected in parallel with said inductor and capacitor. The resistors are selectively clipped to eliminate the echo bringing the impedance of the impedance matching network to approximate equality with the impedance of the wire at the frequency of the high frequency signals.Type: GrantFiled: February 10, 1989Date of Patent: October 26, 1993Assignee: ComSource Systems CorporationInventors: Lawrence W. Hill, Frederick W. Sarles

Patent number: 5245335Abstract: The system comprises transceivers employing identical modems, one located at a fixed position and connected to the wire and one on a vehicle guided along the wire. The transceiver's specialized modems may be connected to a central host which may be a computer, to a programmable controller, or to a communications bus as required. Additional transceivers may be connected to the communications bus for communication between the central host and additional wires. All central host signals are transmitted to all wire connected modems and sent out on all wires. All signals from vehicle modems are transmitted back to the central host. Each transceiver is adapted to employ one or more identical modem, each connected to a different wire.Type: GrantFiled: May 28, 1991Date of Patent: September 14, 1993Assignee: ComSource Systems Corp.Inventors: Lawrence W. Hill, Frederick W. Sarles

Patent number: 4766386Abstract: A time domain reflectometer (TDR) for making impedance measurements on a powered transmission line cable system. The TDR is particularly useful for measuring impedance discontinuities on a powered Ethernet system. A negative test pulse is provided to ensure that any positive reflections do not exceed the upper voltage limit of the transceivers. The TDR selectively applies a negative bias to the transmission line cable below the collision detection threshold in order to disable all transceivers and prevent network interference with the TDR measurements. The negative DC bias also provides additional headroom for positive pulse reflections.Type: GrantFiled: May 23, 1986Date of Patent: August 23, 1988Assignee: CabletronInventors: Christopher J. Oliver, Frederick W. Sarles

Patent number: 4597082Abstract: A multi-drop local area network utilizes alternating current power lines as a transmission channel. Identical transceivers are used as a master and as up to 255 slaves. Each transceiver comprises modulator and demodulator units and a microprocessor control unit which may be connected to a host. The modulator and demodulator are connected to the alternating current power line through a high pass filter comprising a split bobbin, iron core transformer having an air gap which also provides impedance matching. The demodulator includes a clipper and analog circuitry providing a band pass filter and generating a square wave corresponding to the received carrier. A state machine acting as a digital filter produces a received carrier signal only when each half cycle of the carrier square wave is of the proper duration and the carrier signal has existed for slightly more than one half of the transmitted bit duration, which is a predetermined number of carrier cycles.Type: GrantFiled: March 6, 1984Date of Patent: June 24, 1986Assignee: Controlonics CorporationInventors: Lawrence W. Hill, Frederick W. Sarles
