  • Patent number: 11522511
    Abstract: Circuits and methods for using in parallel amplification and signal combining are described herein. A circuit uses a digitally controlled multistage cascade combiner, a digital phase and drive signal amplifier controller and a digital combiner controller circuit with N parallel signals with constant amplitudes belonging to an alphabet with M discrete values and discrete phases feeding it. The signals resulting from N power amplifiers (PAs) have also constant amplitudes belonging to an alphabet with N discrete values and discrete phases prior to being fed to the multistage combiner. A digital combiner controller circuit generates digital control information to activate, or deactivate, the outputs of the PAs, where a set of digital control signals generated in digital combiner controller are used to control sets of switches, where the signals can be activated at the combiner's inputs, according to their power and phase values.

  • Patent number: 11420595
    Abstract: A cleaning unit for cleaning foreign matter from a cover, in particular a cover of a transmitter/receiver window of an environment sensor, including at least one movable wiper blade, which is arranged so as to wipe off foreign matter such as water or dirt on the cover by movement along the cover. For this purpose, the wiper blade touches the cover for example with one or multiple rubber lips. The wiper blade is positioned in an inclined manner with respect to a direction of movement of the wiper blade and is thus movable in such a way that a force exerted by the moved wiper blade on the foreign matter has a component in the direction of the force of gravity. Also described is a related device for sensing the environment as well as a method for cleaning a cover.
