Patent number: 8958766Abstract: An electronic appliance comprising an electrical circuit and an operating mode switching unit which can be awakened out of a sleep state into a working state in which the current consumption of the circuit is greater in than in the sleep state. To receive a radio signal, the appliance has a receiver comprising a UHF carrier that is amplitude-modulated by a modulation signal. The receiver comprises a UHF antenna connected to a passive filter stage to an input of a passive rectifier circuit. An output of the rectifier circuit is connected to a detector for the modulation signal. To wake the electrical circuit from the sleep state, the operating mode switching unit has a control connection to the detector. The appliance has a low current draw in the sleep state by matching the output impedance of the rectifier circuit to the input impedance of the detector.Type: GrantFiled: January 14, 2013Date of Patent: February 17, 2015Assignee: SmartExergy WMS GmbHInventors: Tolgay Ungan, Gerd Ulrich Gamm, Leonhard Michael Reindl, Thomas Ostertag, Matthias Sippel, Thomas Wendt

Patent number: 7714706Abstract: The invention relates to the coupling of a sensor element to a transponder, the connection of said sensor element to the transponder being achieved by capacitive or inductive coupling. This enables any separation layer that may lie between the sensor element and the transponder to be retained, allowing the invention to be advantageously used in gas and liquid-tight containers, such as tires. In addition, electrically non-conductive materials of the object to be measured can be used as a dielectric for the capacitive coupling and electrically conductive parts can form part of a conductor loop for the inductive coupling.Type: GrantFiled: November 13, 2003Date of Patent: May 11, 2010Inventors: Thomas Ostertag, Walter Schacherbauer

Patent number: 7123591Abstract: Crosstalk is eliminated in a transceiver which is operated in a frequency-division-multiplex full duplex mode. The technique is suitable in particular for what is referred to as software-defined telecommunications equipment. The frequency division multiplex transceiver has a baseband block, a transmit path and a receive path which respectively transmit and receive on different frequencies (full duplex mode). Furthermore, an auxiliary transmit path is provided which is connected to the receive path and which adds to the received signal a signal whose phase is shifted by 180° with respect to the phase of the crosstalk portion in the first receive path at the summation or superimposition point and which has the same frequency range as the transmit signal. The auxiliary transmit path is driven here, independently of the first transmit path, by the baseband block so as to minimize the crosstalk sensed by the baseband block.Type: GrantFiled: March 3, 1999Date of Patent: October 17, 2006Assignee: Siemens AktiengesellschaftInventors: Thomas Ostertag, Xihe Tuo
