| 20090040111 | Antenna System for a Radar Sensor - An antenna system for a radar sensor, in particular for ascertaining distance and/or speed in the surroundings of motor vehicles, at least one part of an antenna being situated on a chip which includes at least a portion of the transceiver units of the radar sensor, and at least one second radiation-coupled part which is situated at a distance from the first part over the chip; the first part includes at least one exciter/receiver element which is part of a semiconductor element forming the chip, and the second part is a resonator element which is situated on a support and has a surface which is larger than the surface of the exciter element. | 02-12-2009 |
| 20090243948 | MODULAR UNIT FOR A RADAR ANTENNA ARRAY HAVING AN INTEGRATED HF CHIP - A modular unit for a radar antenna array having an integrated HF chip, at least one antenna element that has a microwave structure, a focusing element situated in the ray path of the radar antenna array upstream of the at least one antenna element, using which an amplified illumination of the HF chip is achieved, has, in particular, an addition-to-structure device, using which focusing elements of different antenna characteristics can be attached to the modular unit. The addition-to-structure device is preferably formed by fasteners such as clamping devices and plug-in devices. Positioning devices can additionally be provided, using which the focusing element can be attached to the modular unit with precision. | 10-01-2009 |
| 20100050836 | Machine tool protective device - A machine tool protective device for a machine tool, having a monitoring unit which is provided for monitoring a protective region assigned to a tool. It is provided that the machine tool protective device has a guiding unit, which is provided for guiding the protective region as a function of a position of the tool. | 03-04-2010 |
| 20100147124 | MACHINE TOOL PROTECTION APPARATUS - A machine tool protection apparatus, for a machine tool, that is provided for monitoring of a protection region associated with a tool, including a first sensor unit that is provided for reception of a first protection signal. The machine tool protection apparatus further includes at least one second sensor unit that is provided for reception of a second protection signal. | 06-17-2010 |
| 20100238068 | RADAR DEVICE - A radar device, particularly for measuring a speed above ground, includes a high-frequency circuit and an antenna. It is provided that the high-frequency circuit is arranged as a high-frequency chip, which has a plurality of antenna outputs, which are connected to the horn antennas via the antenna lines. | 09-23-2010 |
| 20100295721 | RADAR DEVICE - A radar device has an antenna as well as a switching module, the switching module being designed to set an electric signal to be provided to the antenna in such a way that, depending on the switching, the antenna either emits a continuous modulated radar signal for a long range or a pulsed modulated radar signal for a short range. | 11-25-2010 |
| 20100321268 | Antenna array for a radar transceiver and circuit configuration for supplying an antenna array of such a radar transceiver - An antenna array for radar transceivers, in particular for ascertaining distance and/or speed in the surroundings of vehicles, a first antenna part being situated on a carrier and a second antenna part being situated on another carrier situated at a distance from the first. The first antenna part has two generally rectangular primary exciter patches which adjoin each other on one edge, where they are short-circuited toward ground, two primary exciter patches have two separate supply lines, and the second antenna part comprises two mutually separated rectangular secondary exciter patches, which partially cover the primary exciter patches and which have, in the region of the ground short-circuit of the primary exciter patches, in the beam direction, a distance from each other that at least exposes the ground short-circuit. | 12-23-2010 |
