US Patent:

6871487, Mar 29, 2005

Filed:

Feb 14, 2003

Appl. No.:

10/367227

Inventors:

Anthony D. Kurtz - Ridgewood NJ, US
John Chivers - Derby, GB
Alan Epstein - Lexington MA, US

Assignee:

Kulite Semiconductor Products, Inc. - Leonia NJ

International Classification:

F02C009/54

US Classification:

60 39281, 60 3927, 60795

Abstract:

The present invention relates to a system for detecting aerodynamic instabilities in a jet turbine engine having a pressure transducer mounted in the engine. The pressure transducer, welded to a circuit in signal communication with a controller, is adapted to send measured pressure readings from air in a combustion chamber to the controller. The controller, located in spaced apart relation from the engine, is adapted by software to detect pressure patterns from the pressure signals generated by the transducer that are indicative of a stall or surge. A series of fuel and air valves located with compression and combustion chambers of the engine are in signal communication with the controller. The controller in response to detecting pressure signals indicating a stall or surge is operative to signals in the valves to change the air flow, air angle, fuel flow or speed to reduce the possibility of a stall or surge.

International Classification:

G08B013/14

US Classification:

340/572800

Abstract:

An electronic tag enclosure assembly includes an electronic tag and an enclosure having the electronic tag disposed therein. The enclosure optionally reassembles a stuffed toy or sports item. A front side defines a fastener opening through which at least one fastening device extends from the electronic tag to permit fastening to a vehicle surface. The enclosure has an entrance opening for insertion of the electronic tag. The walls of the enclosure optionally include cushioning material. Still further, the enclosure may include or have appended thereto stuffed portions to give the enclosure the appearance of the stuffed toy or sports item. The stuffed portions or cushioning material serve to provide mechanical shock protection. Additionally, the enclosure can serve to identify the electronic tag or to obscure it. Furthermore, the enclosure material serves to protect the electronic tag from the sun's rays.
