William Stephen Caldwell 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: 10054517
    Abstract: Motion detection devices and systems are described herein. One motion detection device includes an inertial measurement unit (IMU) configured to measure velocity, orientation, and gravitational forces of the motion detection device and a computing component. The computing component can be configured to determine spectrum parameters of a mobile vehicle associated with the motion detection device using measurements from the IMU, determine IMU orientation parameters using measurements from the IMU, and estimate motion of the mobile vehicle using the spectrum parameters, the IMU orientation parameters, measurements from the IMU, and a motion estimation function.
    Type: Grant
    Filed: August 22, 2016
    Date of Patent: August 21, 2018
    Assignee: Honeywell International, Inc.
    Inventors: Haiyang Liu, Jeffrey Baker, Charles Joseph Cunningham, IV, William Stephen Caldwell
