Patent number: 9755477Abstract: The aim of the invention is to better compensate for specifiable forces on a magnetic mounting. This is achieved by a magnetic mounting device with a first magnet device (10), which is designed in an annular manner and which has a central axis, for retaining a shaft on the central axis in a rotatable manner by means of magnetic forces. The magnetic mounting device additionally has a second magnet device (12), which is independent of the first magnet device (10), for compensating for a specifiable force acting on the shaft. In this manner, the magnetic mounting device can compensate for the gravitational force or forces based on imbalances.Type: GrantFiled: February 19, 2013Date of Patent: September 5, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Roland Bittner, Markus Hösle, Hilmar Konrad

Patent number: 9691246Abstract: A flame detector, may be aligned to cover a region to be monitored near a body water. The flame detector has at least one radiation sensor and a downstream evaluation unit. The at least one radiation sensor is sensitive to light in the spectrum of open fire. The evaluation unit outputs a fire alarm in the event of fluctuations or flicker frequencies characteristic of open fire being detected. A linear polarizing filter positioned upstream of the radiation sensor(s) has a polarization plane rotated about a main receiving direction to largely suppress the horizontal component of the received light, based on the knowledge that light reflected from water surfaces is predominantly horizontally polarized. If characteristic flicker frequencies and a significant degree of polarization are simultaneously detected in the received light, the detector identifies sunlight reflected off bodies of water and modulated by the swell, and a false alarm output is inhibited.Type: GrantFiled: April 14, 2016Date of Patent: June 27, 2017Assignee: SIEMENS SCHWEIZ AGInventors: Harald Ebner, Hilmar Konrad

Patent number: 9503620Abstract: A method and a system evaluate a security situation in a building. The building has accommodation areas with access authorization for authorized persons. A count of the persons present in the accommodation areas is determined in that, in a radio network which contains a plurality of radio stations arranged spatially distributed in the ceiling, wall or floor, the influencing of the radio field of the radio stations between one another by persons physically present there is evaluated, by a radio tomographic location and detection method. A current count of identifiers which are read by RFID reading devices of RFID transponders is determined, the identifiers being carried by authorized persons. The RFID reading devices are arranged there spatially distributed in the ceiling, wall or floor. Based on the respective counts of personal identifiers and the determined person count, an indicator for evaluating the current security situation in the building is determined.Type: GrantFiled: September 30, 2011Date of Patent: November 22, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Hilmar Konrad, Dieter Wieser
