Publication number: 20200244368Abstract: The present disclosure pertains to systems and methods for low-power optical transceivers. In one embodiment, a low-power optical transceiver may include a microcontroller, an optical receiver, and an optical transmitter in communication with and controlled by the microcontroller. The optical receiver may include a photodetector configured to receive a first optical representation of a first signal to be received and to generate an electrical representation of the first signal. An amplifier may amplify the electrical representation of the first signal, and an output in electrical communication with the amplifier may generate an electrical output. The optical transmitter may include a laser diode configured to generate a second optical representation of a second signal to be transmitted. The microcontroller may be configured to control an output power of the laser diode.Type: ApplicationFiled: April 17, 2020Publication date: July 30, 2020Applicant: Schweitzer Engineering Laboratories, Inc.Inventors: David M. Rector, Raymond W. Rice, Steven Watts, Vince B. Hadley

Patent number: 8683846Abstract: A gas chromatograph operable to analyze a sample gas comprising a carrier gas and components. The gas chromatograph includes a bridge circuit with a sample sensor connected therein. A servo amplifier is connected to the bridge circuit and is operable to maintain the sample sensor at a constant temperature. An output of the servo amplifier is digitized and is used to quantify the components in the sample gas.Type: GrantFiled: September 12, 2011Date of Patent: April 1, 2014Assignee: ABB Inc.Inventors: Vince B. Hadley, Rodney Wayne Dilbeck

Patent number: 7992423Abstract: A feed-through module for an analyzer, such as a gas chromatograph. The feed-through module is adapted for connection to a plurality of tubes and for conveying fluids between the tubes and an enclosed volume of a housing of the analyzer. The feed-through module includes a connection structure threadably secured to the housing and a feed plate removably mounted to the connection structure. A plurality of connectors are secured to the feed plate. The connection structure and the feed plate cooperate to define a plurality of internal flow networks. Each flow network is operable to convey one of the fluids between one of the connectors and the enclosed volume of the housing. Within each flow network, a stream of fluid is split and then recombined.Type: GrantFiled: October 26, 2007Date of Patent: August 9, 2011Assignee: ABB Inc.Inventors: Max A. Bailey, Vince B. Hadley, Stephen P. Paetz

Patent number: 7743641Abstract: The present invention is directed to a gas chromatograph having a display screen. The gas chromatograph includes an explosion-proof housing and a transparent panel secured to the housing. The display screen is disposed in the housing and is visible through the transparent panel. A gas chromatograph (GC) assembly is disposed in the housing and includes a column for separating components of the gas and a detector for detecting the components of the gas. An electronics assembly is disposed in the housing and includes a microprocessor and memory. A graphical user interface (GUI) software application is stored in the memory and is executable by the microprocessor to display a plurality of windows on the display screen. The windows contain information about the operation of the gas chromatograph.Type: GrantFiled: September 1, 2006Date of Patent: June 29, 2010Assignee: ABB Inc.Inventors: Max A. Bailey, Vince B. Hadley, Jonathan W. Asher, Rodney Wayne Dilbeck, Anthony P. Walker, Steven Gene Lakey, Stephen P. Paetz, Brent E. Berry, Robert W. Rutledge
