Patent number: 10495623Abstract: A gas analysis system for analyzing dissolved gas in electrical insulating fluid includes a trap that selectively captures or releases one or more gases, a temperature control device for controlling a temperature of the trap that determining whether the trap is in a gas capture mode or a gas release mode, and a gas sensor for analyzing the gas that was not selectively captured by the trap. The trap may be heated to a first temperature that enables the gas to be adsorbed by the trap, and the trap may be heated to a second temperature that enables the gas to be desorbed by the trap. The gas analysis system may further include a gas flow diverter for directing gas flow past the trap. The captured or released gases may be interfering matrix gases. A method and analyzer for analyzing dissolved gas in an electrical insulating fluid are also disclosed.Type: GrantFiled: November 15, 2016Date of Patent: December 3, 2019Assignee: Serveron CorporationInventors: John Hinshaw, Steven Mahoney, Thomas Waters

Patent number: 8999723Abstract: A reliable, low cost device for determining when dangerous levels of hydrogen gas have been generated in a transformer is disclosed. The hydrogen indicator is defined by a module assembly that threads into either the headspace or into the oil-filled body of a transformer. The module has an open interior that contains a film that incorporates a hydrogen-sensitive chemochromic indicator. The indicator film is visible through a lens. When the film has been exposed to hydrogen, chemical changes in the chemochromic indicator cause the film to change color—the color change is immediately visible through the lens.Type: GrantFiled: April 16, 2014Date of Patent: April 7, 2015Assignee: Serveron CorporationInventor: Steven Mahoney

Patent number: 8142547Abstract: A method for extraction of gas from liquid provides for reliable and accurate extraction of gases dissolved in fluids and routing the extracted gas to an analytical instrument. An extraction module comprises one or more fluorosilicone membranes molded into the shape of a flattened disk. The membranes are retained in a housing in a spaced apart relationship. The membrane is permeable to target gas(es), but not to the fluid. Porous support members support the membranes and prevent damage to them and the housing defines separate fluid flow paths for the fluid and the gas extracted from it. Fluid is passed over the membrane in a first fluid phase; target compounds in the fluid diffuse across the membrane to a second fluid phase until equilibrium is achieved.Type: GrantFiled: November 15, 2011Date of Patent: March 27, 2012Assignee: Serveron CorporationInventors: Steven Mahoney, Thomas Waters

Patent number: 7110804Abstract: A combined audio and electrical anatomy-signal sensor which is designed to collect, essentially from a selected, common anatomical site, related audio and electrical anatomical signals, such as heart-produced signals. The sensor includes a unique body structure which is designed to function both as a part of the audio-information gathering structure, and as a part of electrical electrode structure for gathering electrical signals. Chamber space is provided within this body for receiving and containing desired electrical circuitry, in the form of circuit-board-supported electrical components, which may be designed to perform any one of a number of different functions relative to signal gathering and transferring at and from an anatomical site.Type: GrantFiled: April 24, 2003Date of Patent: September 19, 2006Assignee: Inovise Medical, Inc.Inventors: Martin Baumer, Peter M.

Publication number: 20040254487Abstract: A method and apparatus for controlling in a strip-chart recorder lateral and longitudinal imagery registration for overprinting on pre-printed heart imagery of visual pictorial, heart-related condition-interpretation data. Pairs of parallel and nonparallel control marks, precisely preprinted on a strip-chart page in relation to this pre-printed heart imagery, are observed passing through a prepared zone defined in the recorder. Near (or within) this prepared zone, a fixed-portion printhead, which is employed to perform overprinting, and whose print-active area can be laterally adjusted, is provided. Observation timings of passing control masks are employed to determine both (a) the times when data overprinting should occur, and (b) any necessary lateral printing-area adjustments that should be made, to assure proper printed-imagery registration.Type: ApplicationFiled: June 13, 2003Publication date: December 16, 2004Applicant: Inovise Medical, Inc.Inventors: Steven A. Mahoney, Richard C. Myers

Publication number: 20040220486Abstract: A releasably interconnectible, signal-communicative interface between an anatomical signal sensor and an associated receiving coupler-adapter. Through complementary male and female interconnection structures, this interface is designed to accommodate both a mechanical, and an electrical, releasably locked cross-connection between such a sensor and a coupler-adapter. Spring-biased cam-interengaging interface components, including a cam surface on the sensor, and a pair of relatively moveable opposed clamping arms on the coupler-adapter operate, during the act of connection, to draw a sensor projection into a connected condition within a socket provided in the coupler-adapter. A springy, electrically conductive component in the adapter plays both mechanical and electrical roles in relation to operation of the interface.Type: ApplicationFiled: April 29, 2003Publication date: November 4, 2004Applicant: Inovise Medical, Inc.Inventors: Martin Baumer, Peter M.

Publication number: 20040214478Abstract: A coupler-adapter which is employable in an anatomical signal path that extends between an anatomical signal sensor, such as an ECG electrical sensor, including one which may also be designed to collect audio information, and external signal-reception structure. The couple-adapter includes body structure which may be directly connected to such a sensor, and which includes plural sensor reception regions that are configured to receive and accommodate, mechanically and electrically, plural different types of such sensors.Type: ApplicationFiled: April 24, 2003Publication date: October 28, 2004Applicant: Inovise Medical, Inc.Inventors: Martin Baumer, Peter M.
