Patents by Inventor Cees J. Roos

Cees J. Roos 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).

  • Spectrometer sequential readout system
    Patent number: 4214835
    Abstract: A spectrometer readout system with storage capacitors for temporarily storing output signals generated by a series of photomultiplier tubes that are positioned to monitor selected spectral lines. A voltage-time converter sequentially discharges the capacitors to a preset level and converts the stored voltages into signals that are linearly related to a known signal and an unknown signal. The output of the voltage-time converter defines the discharge time period which is measured and stored by a computer.
    Type: Grant

  • Spectrometer sequential readout system
    Patent number: 4140394
    Abstract: A spectrometer readout system with storage capacitors for temporarily storing output signals generated by a series of photomultiplier tubes that are positioned to monitor selected spectral lines. A voltage-time converter sequentially discharges the capacitors to a preset level and converts the stored voltages into signals that are related logarithmically to a known signal and an unknown signal. The output of the voltage-time converter defines the log discharge time period which is measured and stored by a computer.
