Patents by Inventor Stanley D. Goldring

Stanley D. Goldring 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).

  • Electro-optical coupler for catheter oximeter
    Patent number: 4684245
    Abstract: An optical module couples a fiberoptic catheter to a catheter oximeter processing apparatus. The module includes a plurality of LED's for coupling the electrical control signals from the processor and converting them to light signals to transmit to the catheter. The module also includes the means to convert the received reflected light signals from the catheter to electrical signals to be transmitted to the processor. The module further includes a memory to store calibration signals and other data so that the module and catheter can be disconnected from the processor and used with a different processor without necessitating a recalibration.

  • Apparatus for determining oxygen saturation levels in blood
    Patent number: 4523279
    Abstract: A signal filter method and apparatus for removing portions of a signal indicative of erroneous data, an exemplary apparatus including means for receiving the signal, means for adjusting a threshold by increasing the threshold a first predetermined amount when the signal is in a predetermined relationship with the threshold and for decreasing the threshold a second predetermined amount when the signal is in a second predetermined relationship with the threshold, and means for comparing the signal with the adjusted threshold and for transmitting the signal if the signal bears a first predetermined relationship to the threshold. Disclosed herein are digital and analog implementations of the signal filter method and apparatus, particularly suited for use with catheter-type oximeter apparatus.
