Patent number: 8471720Abstract: An apparatus for monitoring at least supply voltage in an IC includes a plurality of monitor circuits distributed throughout the integrated circuit. Each of the monitor circuits is operative to receive the supply voltage, or a signal representative thereof, and to generate an output signal indicative of a comparison between the supply voltage and a reference voltage. The apparatus further includes a control circuit coupled to the plurality of monitor circuits. The control circuit is operative to receive the respective output signals from the plurality of monitor circuits and to generate an output of the apparatus which is a function of information conveyed in the respective output signals from the plurality of monitor circuits.Type: GrantFiled: November 17, 2010Date of Patent: June 25, 2013Assignee: LSI CorporationInventors: Mark Franklin Turner, Jeffrey S. Brown, Jonathan W. Byrn

Patent number: 8432210Abstract: An apparatus for controlling clock skew in an integrated circuit (IC) includes timing circuitry operative to generate a clock signal for distribution in the IC and at least one buffer circuit operative to receive the clock signal, or a signal indicative of the clock signal, and to generate a delayed version of the clock signal as an output thereof. The buffer circuit includes at least first and second inverter stages and a resistive-capacitive (RC) loading structure. An output of the first inverter stage is connected to an input of the second inverter stage via the RC loading structure. The buffer circuit has a delay associated therewith that is selectively varied as a function of one or more adjustable characteristics of the RC loading structure. Clock skew in the IC is controlled as a function of the delay of the buffer circuit.Type: GrantFiled: November 2, 2010Date of Patent: April 30, 2013Assignee: LSI CorporationInventors: Jeffrey S. Brown, Mark Franklin Turner

Patent number: 7351126Abstract: The invention is directed to a wetsuit/floatation device which advantageously provides a combination wetsuit/flotation device integral with the wet suit so that a user can maintain unrestricted movement during water-sport activities and have the option of gaining instant buoyancy during times of dangerous water conditions. The invention can be made in a number of embodiments, with one being a vest which can be worn over a person's skin or over another wetsuit. The vest has an inflatable bladder extending from two chest panels around the back of the user's neck, with a valve connected to a removable CO2 canister which is triggered by a pull cord/handle extending outside of the wetsuit. The vest also has an inflation adjustment valve located near the neck by which a user can orally inflate or adjustably deflate the vest.Type: GrantFiled: November 21, 2005Date of Patent: April 1, 2008Inventor: Franklin A. Turner

Patent number: 6976894Abstract: The present invention advantageously provides a combination wet suit and flotation device integral with the wet suit so that a user can maintain unrestricted movement during water-sport activities, which improves convenience and comfort. A wet suit worn by water-sport a participant includes a torso section having a pocket provided with a movable flap and a waterproof seal. A CO2 canister is housing with the pocket and includes a strap positioned thereabout for securing the canister during operating conditions. A pull cord is connected to the canister and associated valve for actuating the flow of CO2 into a bladder defined adjacent the torso section of the wet suit. In operation, when a user pulls the cord, the canister inflates the bladder for assisting to maintain a user's head above the water line.Type: GrantFiled: September 24, 2004Date of Patent: December 20, 2005Inventor: Franklin A.

Patent number: 6884959Abstract: This invention relates to a method and apparatus for controlling the composition of a weld. More particularly it relates to welding using an electric circuit, thereby creating a weld puddle, and adding at least one filler that is electrically independent from the electric circuit to the weld puddle at a controllable rate to obtain a target weld composition. The filler can be added to the extent limited by practical weld puddle geometry and, thus, the method and apparatus also facilitate increased weld deposition rates.Type: GrantFiled: September 7, 2001Date of Patent: April 26, 2005Assignee: Electric Power Research Institute, Inc.Inventors: David Wayne Gandy, James William Hales, William Frederick Newell, Jr., Roger Allen Swain, James Franklin Turner, Ramaswamy Viswanathan

Patent number: 4424529Abstract: A stereoscopic viewer system receives a synchronization signal input from a left-right stereoscopic image pair production system. A viewer system has a transmitter and a modulator associated therewith to transmit into a medium a carrier signal modulated with the synchronization signal. A transmitted signal is received by a receiver which has a demodulator to extract the synchronization signal and to supply it to switching logic. The switching logic supplies switching signals to alternately operate selectively and in accordance with the synchronizing signal each of a pair of electro-optic shutters between the maximum and minimum optical transmission state. Each shutter is positioned in the line of sight of one of the eyes of a user. The system receiving means is powered by a battery power supply.Type: GrantFiled: March 3, 1980Date of Patent: January 3, 1984Inventors: John A. Roese, A. Franklin Turner

Patent number: 4214267Abstract: A stereofluoroscopy system has a source of radiation to radiate an object. The source may be one or two x-ray tubes. Conversion means receives radiation from the source and converts it into a composite video signal. The conversion means may include an image intensifier tube associated with a conventional television camera. The composite video signal is received by transmission means which may include switching apparatus and circuitry together with a video storage device to selectively receive even and odd fields for subsequent transmission to display means. The display means includes a television monitor to receive the video signal and a field synchronization detector to detect the video synchronization signal. Means are provided to transmit a synchronization signal to portable electro-optic shutter viewers to be positioned in front of the eyes of the viewer to obtain a three-dimensional stereoscopic view of the television monitor.Type: GrantFiled: November 23, 1977Date of Patent: July 22, 1980Inventors: John A. Roese, A. Franklin Turner
