Patents by Inventor William Montren

William Montren 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: 4341117
    Abstract: An electronic computer which provides an accurate final temperature reading prior to the actual stabilization of the temperature sensor. An algorithm is provided which allows making only two temperature measurements at preselected times yet accurately predicts the end stabilization temperature. A temperature resistance varying is converted to a temperature-frequency varying signal, clocked into an up/down counter, then displayed digitally. A thirty second timing sequence is also digitally displayed for use when the invention is utilized for medical applications.
    Type: Grant
    Filed: June 11, 1976
    Date of Patent: July 27, 1982
    Assignee: Patient Technology, Inc.
    Inventors: Harold Goldstein, William Montren
  • Patent number: 3978325
    Abstract: An electronic apparatus to measure temperature which provides an accurate final temperature reading prior to the actual stabilization of the temperature sensor. An algorithm is provided which allows taking only two sensor temperature measurements at preselected times yet accurately predicts the sensor final or stabilization temperature. Temperature resistance varying signals are converted to temperature-frequency varying signals, clocked into an up/down counter, to compute final temperature which is displayed digitally. A thirty-second timing sequence is also digitally displayed for use when the invention is utilized for medical applications.
