Patents by Inventor Reinhard Ritschel

Reinhard Ritschel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7733071
    Abstract: The invention relates to smoothing a consumer electrical circuit supplied by a controllable current sink connected in parallel to the consumer. For this purpose, measuring voltage proportional to a load current supplied to the consumer is derived therefrom. A pick value measuring device makes it possible to determine a maximum value thereof. The difference between the maximum value and measuring voltage makes it possible to control the voltage-controlled current sink in such a way that the sum of a compensation current supplied by the current sink and the load current which runs by the consumer is substantially constant.
    Type: Grant

  • Patent number: 6999524
    Abstract: The invention relates to an arrangement for controlling the output power of a high-frequency transmitter. The control power of the transmitter output stage is controlled according to a correcting variable (R) and by means of an actuator, whereby said variable is obtained by comparing the output power to a desired value (S). An I./Q modulator (M) is used as actuator.
