Publication number: 20090302699Abstract: In a magnetic bearing arrangement, support coils are connected in series and can be fed with a current. By coupling a point connecting the two support coils to a voltage source, the support coils can be used as actuating elements and, by feeding the support coils with voltage pulses, the inductance of the support coils can be inferred which is an indication of the position of the body to be mounted. This provides for a position control arrangement. Using one and the same support coils, both a stably controlled load-bearing capacity can thus be produced and at the same time a position sensor can be replaced.Type: ApplicationFiled: June 3, 2009Publication date: December 10, 2009Applicant: Siemens AktiengesellschaftInventors: JOACHIM DENK, Hans-Georg Kopken, Dietmar Stoiber, Bernd Wedel

Publication number: 20090273437Abstract: A key-operated switch includes a first excitation device which generates a first alternating magnetic field and has a first inductance. The key-operated switch is constructed in such a manner that the first alternating magnetic field can be used to scan a first coding of a key, with the first coding changing the first inductance of the first excitation device. The first coding is read by the key-operated switch in this manner. The key associated with the key-operated switch has a carrier element which is not electrically conductive and is not magnetizable. Arranged on the carrier element is the first coding which is made of an electrically conductive and/or magnetizable material. As a result, the key can be scanned without wear.Type: ApplicationFiled: April 29, 2009Publication date: November 5, 2009Applicant: Siemens AktiengesellschaftInventors: Hans-Georg Kopken, Christiane Muller, Richard Schmidt, Gunter Schwesig
