20160007427 | METHOD AND SYSTEM FOR ACTUATING LOADS CONNECTED TO A BUS SYSTEM - A method for actuating loads connected to a bus system, in particular lamp operating devices, by at least one command generator which is likewise connected to the bus system. The actuation is carried out by the transmission of data packets, wherein the command generator fills a data packet region assigned to the command generator after the data packet transmission is initiated by a central clock generator. | 01-07-2016 |

20100154940 | MELT-TREATED RIM OF A PISTON COMBUSTION BOWL - A method for producing pistons that can be used in internal combustion engines made from lightweight metal, with a combustion bowl assigned to one piston head, wherein a bowl rim is subjected to a melt treatment. In a first method step, the bowl rim is inductively heated. In a second method step, the material of the bowl rim, also to be referred to as the delimiting zone, is improved by means of a laser beam. | 06-24-2010 |

20080219301 | Sweep Speed Compensation - A method of manipulating a laser source, includes analyzing an optical signal generated by the laser source, evaluating on the basis of the analysis an actual indicator corresponding with an actual value of a tuning velocity of the laser source, comparing the actual indicator with a desired indicator corresponding with a desired value of the tuning velocity to detect a deviation of the actual value of the tuning velocity from the desired value of the tuning velocity, and compensating the deviation if any by manipulating at least one parameter influencing the signal of the laser source. | 09-11-2008 |
20090303108 | Angular Resolution Radar Sensor - A radar sensor having multiple antenna elements for transmitting and receiving radar signals, an associated transmitting and receiving element and an evaluation device for determining the azimuth angle of located objects on the basis of a relationship between the signals received from different antenna elements, wherein the transmitting and receiving element is designed to supply to the antenna elements transmission signals in parallel, the frequencies of which are offset with respect to one another, and the evaluation device is designed to distinguish between signals that were transmitted by different antenna elements on the basis of the frequency offset. | 12-10-2009 |
20110037641 | METHOD FOR OPERATING A RADAR AND RADAR - A method for operating a radar, having the following steps: determining first and second differential signals from a first and second transmitted frequency-modulated signal and received components of the first and second transmitted frequency-modulated signal reflected by a plurality of objects; determining in each case one first and one second chirp signal for each first and the second differential signal, the first chirp signal corresponding to the double differentiation of the phase of the first and the second differential signal with respect to time; assigning one of the first differential signals to one of the second differential signals, based on a correspondence of the first chirp signal, that is assigned to the one first differential signal, to the second chirp signal that is assigned to the one second differential signal; and determining the separation distance and/or the relative speed of one of the objects, based on the one first differential signal and the one second differential signal assigned to the first differential signal. | 02-17-2011 |
20120146835 | FMCW RADAR SENSOR AND METHOD FOR FREQUENCY MATCHING - In a method for frequency matching in an FMCW radar sensor, a plurality of frequencies, which are derived on various modulation ramps, and which respectively are shown by the radar sensor in a d-v space as geometrical locations, represent possible combinations of a distance d and a speed v of the respective object. In order to identify the objects located on the various modulation ramps, coincidences between the geometrical locations which belong to frequencies derived on various modulation ramps are searched for. The search for coincidences is initially restricted in a first step to a subspace of the d-v space, and in a subsequent step, the search is extended to other regions of the d-v space, while suppressing the frequencies that are associated with the objects found in the first step. | 06-14-2012 |
