Patents by Inventor Alexander Grichener

Alexander Grichener 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: 7994940
    Abstract: The invention provides a sensor for determining when a latch for securing an engine cowl on an aircraft is secured by detecting the proximity of a latch hook and a latch pin. The sensor includes a resonant circuit configured and adapted to transmit a status signal when the latch is in a secured state. The sensor also includes a means for conveying status information of the latch to a location remote from the latch based on the status signal, the conveying means being operably connected to the resonant circuit. The invention also provides a method of determining when a latch is open or secured by detecting the proximity of a latch hook and a latch pin.

  • Patent number: 7603915
    Abstract: A force balanced mass flow meter is disclosed that includes a cylindrical sensor housing having an interior bore, an impeller body supported for axial rotation within the interior bore of the sensor housing, and including structure for converting fluid inertia into flow induced torque when fluid flows relative to the impeller body, a proximity sensor for measuring a rotation angle of the impeller body relative to the sensor housing, an electromagnet for generating a magnetic field about the sensor housing to prevent rotation of the impeller body, electronics for determining electrical values from the proximity sensor when fluid flows relative to the impeller body and a controller for controlling current supplied to the electromagnet in response to electrical values determined from the proximity sensor, to generate a magnetic field sufficient to prevent impeller rotation.
