20110001659 | DEVICE AND METHOD FOR THE IMPROVED DIRECTIONAL ESTIMATION AND DECODING BY MEANS OF SECONDARY RADAR SIGNALS - 1. A device and a method for the improved directional estimation and decoding by means of secondary radar signals. 2.1 Radio-based positioning systems on the basis of secondary radar signals are known. For this purpose special receiver systems are utilized for estimating the direction, and special receiver systems are utilized for decoding secondary radar signals. In particular, a secondary radar system is absent, which, among others, takes into consideration any shortcomings of the hardware used, such as coupled antenna elements, different low-end impedances, deviating distances between the antenna elements, manufacturing and installation tolerances, and the like. 2.2 The device for directional estimation and/or decoding secondary radar signals according to the invention comprises the following: —at least one array A comprising M antenna elements AE—an amplifier LNA and bandpass filter F | 01-06-2011 |

20110224935 | MEASUREMENT DEVICE, PARTICULARLY ENERGY COUNTER AND METHOD FOR RECOGNITION OF MANIPULATIONS - There are various systems designed for outputting counter data that are primarily collected under the term AMM systems today (AMM: Automatic Meter Management). Lacking in practice, however, is a consumption counter and a method for recognition of manipulations that is universally applicable, independently of other technical conditions, and that gives the customer the option for self-monitoring (consumption/leaks, etc.) locally. | 09-15-2011 |

20120092211 | DEVICE FOR RECEIVING SECONDARY RADIO SIGNALS WITH QUASI-DYNAMIC OR DYNAMIC SECTORING OF THE SPACE TO BE MONITORED AND CORRESPONDING METHOD - A device and method for secondary radar signal reception with quasi-dynamic or dynamic sectoring of a space to be monitored. The device includes at least one antenna assembly including antenna elements for the reception of transmitted secondary radar signals, a signal processing unit connected via a connection point to the antenna elements for the joint processing of received antenna signals, outputs associated with a couple matrix in the signal processing unit and individual receivers. The couple matrix includes adjustable coefficients for sectoring of the space to be monitored and for performing a superposition of the antenna signals using a multiplicative-additive combination of the received antenna signals. In the case of dynamic sectoring of the space, each receiver receives for each receipt telegram another weighted superposition of the antenna signals with certain couple coefficients, and in the case of quasi-dynamic sectoring the adjustable coefficients are fixed over a longer time period. | 04-19-2012 |
20120148103 | METHOD AND SYSTEM FOR AUTOMATIC OBJECT DETECTION AND SUBSEQUENT OBJECT TRACKING IN ACCORDANCE WITH THE OBJECT SHAPE - A method and system for automatic object detection and subsequent object tracking in accordance with the object shape in digital video systems having at least one camera for recording and transmitting video sequences. In accordance with the method and system, an object detection algorithm based on a Gaussian mixture model and expanded object tracking based on Mean-Shift are combined with each other in object detection. The object detection is expanded in accordance with a model of the background by improved removal of shadows, the binary mask generated in this way is used to create an asymmetric filter core, and then the actual algorithm for the shape-adaptive object tracking, expanded by a segmentation step for adapting the shape, is initialized, and therefore a determination at least of the object shape or object contour or the orientation of the object in space is made possible. | 06-14-2012 |
20120281746 | DEVICE AND METHOD FOR IDENTIFICATION AND CANCELLATION OF CROSSTALK - Devices and methods for the cancellation for and identification of crosstalk for different application cases, particularly for near-end crosstalk (NEXT), are known. Too little attention is paid to the situation of non-reciprocally coupled systems. Therefore, devices and methods for cancellation and identification of far-end crosstalk (FEXT), which enable a reliable identification of an unknown system, are lacking in practice. | 11-08-2012 |
20130063228 | RECONFIGURABLE BANDPASS FILTER BASED ON A PLANAR COMBLINE FILTER COMPRISING VARACTOR DIODES - A reconfigurable bandpass filter including at least a tunable planar combline filter including varactor diodes arranged on a carrier board. For automatic calibration of adjustment of blocking voltage during operation, the reconfigurable bandpass filter includes a filter control offering an external abstracted interface. A memory is connected with the filter control. The memory stores calibration data. For approximating of the best possible filter characteristic, the filter control determines, based on memorized data, the best configuration of tuning voltages. | 03-14-2013 |
20140354353 | DEVICE HAVING A DELTA-SIGMA MODULATOR AND A SWITCHING AMPLIFIER CONNECTED THERETO - A delta-sigma modulator for a switching amplifier, which achieves a high signal-to-noise ratio (SNR) in the multi-MHz range and keeps the noise-transfer function over the useful frequency range as low and as flat as possible.
