Lenard Hirshman 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).

  • ASM output ultrasonic oxygen sensor
    Patent number: 7574894
    Abstract: A gas measuring method, apparatus and system for measuring a concentration of a gas of interest is disclosed. The gas concentration is based on a propagation delay of a sonic or ultrasonic wave as the wave travels through the gas. The propagation delay is measured such that delay contributions from sources other than the gas itself are canceled. A sensor in accordance with the invention includes an sonic or ultrasonic transmitter and receiver, and a control module for performing calculations. The sensor can be used in various applications, including on-board inert gas generating systems (OBIGGS).
