Filed:

Apr 28, 2010

Appl. No.:

12/769408

Inventors:

James W. Heffel - Lake Matthews CA, US
Paul B. Scott - Northridge CA, US
Chan Seung Park - Yorba Linda CA, US

Assignee:

The Regents of the University of California - Oakland CA

International Classification:

F02B 43/00

US Classification:

123 1A, 123494

Abstract:

An apparatus and method for utilizing any arbitrary mixture ratio of multiple fuel gases having differing combustion characteristics, such as natural gas and hydrogen gas, within an internal combustion engine. The gaseous fuel composition ratio is first sensed, such as by thermal conductivity, infrared signature, sound propagation speed, or equivalent mixture differentiation mechanisms and combinations thereof which are utilized as input(s) to a “multiple map” engine control module which modulates selected operating parameters of the engine, such as fuel injection and ignition timing, in response to the proportions of fuel gases available so that the engine operates correctly and at high efficiency irrespective of the gas mixture ratio being utilized. As a result, an engine configured according to the teachings of the present invention may be fueled from at least two different fuel sources without admixing constraints.

Steve R. Vezerian - Arcadia CA

International Classification:

G08B 2100

US Classification:

340603

Abstract:

A warning announcer for a gasoline dispenser having a pump flow counter, a pump bar switch and/or a nozzle position sensor, a dispenser nozzle, and a nozzle receptacle, including a logic unit, a timer, a speaker, a voice alarm unit for providing a message to the speaker, a circuit for connecting signals from the pump flow counter and the pump bar switch or position sensor to the logic unit for controlling the timer to produce a message signal, and a circuit for connecting the timer to the voice alarm unit for initiating a message when the timer produces a messages signals.

Appl. No.:

5/717607

Inventors:

Paul B. Scott - Topanga CA

Assignee:

Xonics, Inc. - Van Nuys CA

International Classification:

F24J 302

US Classification:

126270

Abstract:

An apparatus for collecting solar energy wherein a heat exchange array of plastic or the like is protected against damage by excessive heat buildup. The array is housed in a normally closed chamber having a portion transparent to solar rays and the chamber is periodically vented by means responsive to heat expansion of the enclosed array. The invention permits substantial cost reductions in solar heat exchanges; particularly of the type adapted to heat buildings, swimming pools and domestic water systems.
