Publication number: 20040245390Abstract: An emergency oxygen supply system for an aircraft provides that oxygen may be made available additionally to the breathing gas supply which is brought along on board the aircraft. A gas distribution system supplies breathing masks with oxygen from one of a first oxygen source in the form of a pressurized gas source or a chemical oxygen generator. A second oxygen source is in the form of a molecular sieve bed arrangement. A change-over device selectively connects the gas distribution system to the first oxygen source or to the second oxygen source. A measurement probe delivers a status signal corresponding to a predefined flight altitude. A control unit delivers a change-over signal from the first oxygen source to the second oxygen source to the change-over device given the presence of the status signal.Type: ApplicationFiled: May 21, 2004Publication date: December 9, 2004Inventors: Rudiger Meckes, Herbert Meier, Wolfgang Rittner

Patent number: 6489886Abstract: A security system to prevent unauthorized starting of the engine of a vehicle has a remote control unit (18) equipped with a transponder which, on reception of an interrogation signal using at least one reception aerial (20), transmits an identification code group using a transmitter unit (40). Located in the vehicle is a control unit (12), which on actuation of a starter button (26) within the vehicle, transmits the interrogation signal, and subsequently checks the identification code group transmitted by the remote control unit. Starting of the engine will only be possible when the identification code group coincides with the code group expected by it. Connected to the reception aerial (20) is a signal detector (28), which has a reaction threshold level that can be toggled between a high value and a low value. This signal detector will relay the interrogation signal to further processing stages only when the interrogation signal level exceeds the set reaction threshold.Type: GrantFiled: April 17, 2001Date of Patent: December 3, 2002Assignee: Texas Instruments Deutschland, GmbHInventor: Herbert Meier

Patent number: 5970148Abstract: Novel means of achieving increased security while still obtaining a low cost, manufacturable device are disclosed and claimed. The first mode of operation is the learn mode which provides means for initial checkout with no security. In the learn mode of operation, the interrogator and transponder may be switched to a predetermined error detection algorithm, i.e. CCITT(Start Mask, CCITT Mask), and certain information is programmed into the transponder memory. During programming, all the bits received from the interrogator are shifted through the preintialized CRC generator. In addition, once the transponder response is sent back to the interrogator, the response is also shifted through a preinitialized CRC generator within the interrogator(which could be a software implementation). Because neither the Cypher Key nor the Function Key are directly readable once programmed, an encryption must be performed to verify the proper Cypher Key and Function Key were programmed into the transponder's memory.Type: GrantFiled: May 2, 1997Date of Patent: October 19, 1999Assignee: Texas Instruments Deutschland, GmbHInventor: Herbert Meier
