Patent number: 11474226Abstract: An apparatus for emitting electromagnetic radiation and receiving partial radiation reflected by objects, and determines the instantaneous performance of its system detection. The apparatus includes a device for emitting a frequency-modulated transmit signal that has at least two signal sequences which have ramps, each succeeding one another in the frequency characteristic, with gaps in between, the signal sequences being interleaved with each other with a predetermined time offset so that in each case a first ramp of each of the signal sequences is output before a second ramp of one of the at least two signal sequences is output. The apparatus includes a mixer, an analog-to-digital converter, a transform device, and a device for detecting phase noise. The phase changes of the receive signals are compared over all two-dimensional spectra to a precalculated model, and the cause of the phase noise is ascertained with the aid of predetermined criteria.Type: GrantFiled: September 1, 2020Date of Patent: October 18, 2022Assignee: Robert Bosch GmbHInventors: Benedikt Loesch, Rolf Noethlings

Patent number: 7433476Abstract: In an automatic gain control unit, the gain of a voltage-controlled amplifier (VCA) (25) is regulated with a closed-loop control circuit. The time constant of the control circuit is varied dependent on the magnitude (31) of the VCA output signal. As long as the magnitude (31) of the VCA output signal is small, the gain is slowly adjusted. In case the magnitude (31) of the VCA becomes so large that saturation of the analog-digital converter (28) might occur, the time constant of the control circuit is decreased, in order to allow for a quick adjustment of the amplifier's gain.Type: GrantFiled: September 24, 2002Date of Patent: October 7, 2008Assignee: Sony Deutschland GmbHInventors: Jens Wildhagen, Carsten Merkle, Dietmar Schill, Rolf Nöthlings, Taiwa Okanobu

Patent number: 7225214Abstract: A digital filter realization is proposed that consists of only one multiplier, i. e. which operates with a higher clock rate and changes coefficient at the multiplier each clock cycle, but in which the clock rate of the multiplier is reduced in comparison to prior art filters by considering equal filter coefficients, e. g. based on the symmetry of FIR filter coefficients. According to the present invention preferably the samples belonging to equal filter coefficients are added in advance in order to reduce the number of multiplications, which concludes in a reduced clock rate for the filter, a reduced needed calculation power, and therefore a reduced power consumption.Type: GrantFiled: September 27, 2002Date of Patent: May 29, 2007Assignee: Sony Deutschland GmbHInventors: Rolf Nöthlings, Jens Wildhagen
