20140340253 | IMAGING RADAR SENSOR WITH NARROW ANTENNA LOBE AND WIDE ANGLE DETECTION RANGE - The invention relates to a device for detecting objects within a sweep range, comprising at least two switchable transmitting antennas, a plurality of receiving antennas, the transmitting antennas and receiving antennas respectively extending longitudinally, parallel to one another, in a first direction, and the receiving antennas being arranged in a row and the row extending in a second direction, the receiving antennas and the transmitting antennas being arranged such that they produce a synthetic receiving antenna array for the beam sweep by means of the sequential activation of the transmitting antennas and the positions of the transmitting and receiving antennas, the resulting distance corresponding to the positions of the receiving antennas in the synthetic receiving antenna array in the second direction d, the adjacent receiving antennas in the device being spaced apart by a distance of d | 11-20-2014 |
20140306840 | IMAGING RADAR SENSOR WITH SYNTHETIC ENLARGEMENT OF THE ANTENNA APERTURE AND TWO-DIMENSIONAL BEAM SWEEP - A device and a method for determining the position of an object, in particular of a moving object, in a three dimensional space is made available. Here the device comprises at least two switchable transmitting antenna arrays having different vertical beam alignments and a number of receiving antennas arranged in a row. The transmitting antennas are arranged spaced apart by a distance that corresponds to the distance between the outer phase centres of the receiving antennas. Otherwise the transmitting antennas can be positioned arbitrarily around the receiving antenna. The horizontal beam sweep over a wide angle range is implemented by the “digital beam forming” method. The vertical object position is measured by comparing the amplitude of the received signals with sequentially operated transmitting antennas having different vertical beam directions. | 10-16-2014 |
20130113501 | DOUBLE PISTON ROD - A distance measuring apparatus for detecting the position of a reflection body in a line structure is provided that includes a sensor device, which has at least one antenna for feeding a transmission signal as an electromagnetic wave into the line structure and for receiving the electromagnetic wave reflected on the reflection body. The sensor device also includes evaluation electronics which are configured to determine the position of the reflection body from the phase difference between the transmitted and the received wave. | 05-09-2013 |
20130015997 | DISTANCE MEASURING DEVICE AND METHOD FOR DETERMINING A DISTANCE, AND A SUITABLE REFLECTIVE MEMBER - A distance measuring device and a method for determining a distance are provided. The distance measuring device includes a reflective member, evaluation electronics and a sensor device having at least one coupling probe for feeding a transmission signal into a line structure with the reflective member. The reflective member includes a base plate with an attached collar for forming a cup-shaped element. | 01-17-2013 |
20120262333 | BEAM POSITION MONITOR FOR ELECTRON LINEAR ACCELERATOR - Electron linear accelerators are used to generate X-ray radiation for the treatment of tumors. Efficient irradiation of tumors can only be guaranteed if the electron beam is guided accurately and so the required dose profile is applied. The deviation from the ideal path of the electron beam is measured by means of so-called beam position monitors and then corrected by magnets. | 10-18-2012 |
