Patents by Inventor Karl U. Stein

Karl U. Stein 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: 5071491
    Abstract: A frame for securing solar cell equipment in a solar generator and carrying solar generated current. The current carrying frame reduces the number of interconnections required in the overall device. As a result, the present invention is simpler and requires considerably less outlay than conventional solar generators.
    Type: Grant

  • Patent number: 4320302
    Abstract: In the exemplary embodiments, two line-shaped images of a scene are imaged onto two line sensors. The output signals of these line sensors are digitally further processed, whereby the distance measurement ensues by means of sequential examination of the correlation of the digitalized measuring results of the line sensors. For the correlation examination, the parts of the line sensors respectively lying opposite one another and overlapping are employed. The circuit arrangement for implementing this method is contained on one chip in MOS digital technology.

  • Patent number: 4290120
    Abstract: A circuit arrangement is disclosed for reading out and regenerating items of information stored in one-transistor storage elements. For read-out, storage elements addressed by the activation of a word line transfer an existing information charge into assigned bit lines, and wherein the bit lines influence inputs of assigned read-out/regenerating amplifiers. The storage density of semiconductor stores is increased by providing a circuit arrangement in which the disproportion in terms of area between technologically realizable storage matrices and the required amplifiers which is a by-product of the miniaturization of stores of the above mentioned type does not occur. A group of m bit lines are in each case combined to form groups and are consecutively connected via a multiplexer to a common read-out/regenerating amplifier.
