Steven J. Lassman 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: 5825414
    Abstract: A circuit within a video monitor for making corrections during horizontal scan includes a data storage device containing information relating to a selected display parameter, an integrator receptive of the stored information and adapted to produce an integrated signal therefrom, and an amplifier receptive of the integrated signal for supplying signals to the video monitor based on the integrated signal. The information supplied from the data storage device to the integrator is encoded in a pulse density modulated wave form via a tri-state gate and a one-shot timer. The information stored in the data storage device is stored in bytes, each byte containing a "sign bit" and a plurality of data bits.
    Type: Grant
    Filed: January 16, 1996
    Date of Patent: October 20, 1998
    Assignee: Display Laboratories, Inc.

  • Patent number: 4907449
    Abstract: A radiosonde has a novel and improved measuring circuitry for measuring atmospheric conditions, such as, temperature, humidity and pressure through the direct conversion of resistance and capacitance values into binary numbers. The binary numbers are transmitted in digital form along with calibration coefficients to a remote ground station. The measuring circuitry can be mounted on the same substrate with the pressure transducer, and the electrical connections between the pressure transducer and measuring circuitry are simplified by utilization of an offset diaphragm, pressure cell arrangement.
