Patents by Inventor A. A. Josephus Den Ouden

A. A. Josephus Den Ouden 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).

  • Phase-coupled clock signal generator and character generator comprising such a phase-coupled clock signal generator
    Patent number: 8451968
    Abstract: A phase-coupled clock signal generator comprises a start-stop oscillator (1) to which a control signal is applied. The clock frequency is dependent on an adjusting value (F). For adjusting and monitoring the clock frequency, the clock signal generator is provided with a counter (2). This counter counts the number of received clock pulses during a predetermined period and generates a corresponding counting value (C). A control circuit (3) compares the counting value (C) with a reference value and adapts the adjusting value (F). Such a clock signal generator is suitable for On Screen Display applications in a television receiver.

  • Data communication using constant total current
    Patent number: 8027405
    Abstract: A data communication system, comprising at least three signal conductors and a first and a second power supply terminal, for supplying currents of mutually opposite direction to the signal conductors respectively. A driver circuit establishes respective combinations of currents through the signal conductors from a selectable set of combinations, which includes combinations with currents from the first supply terminal and to the second supply terminal, so that a sum of the currents through the signal conductors substantially has a same value for each combination and at least one of the conductors in operation does not merely function in a differential-pair relation with another one of the conductors, the driver circuit determining which of the combinations from the set are established depending on information to be transmitted.
