Patents by Inventor Edward April

Edward April 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: 6882143
    Abstract: In an inductive sensor a ferrous core is provided and has generally opposed first and second ends. A winding assembly surrounds the core. First and second magnets are coupled to the first and second ends of the core and are oriented relative to one another so that like magnetic poles are opposing one another along a length defined by the core.
    Type: Grant

  • Publication number: 20040017192
    Abstract: An orientation sensor includes a sensor body. At least four magnetic sensors are coupled to the sensor body. The sensors are positioned in a non-planar arrangement, one relative to the other. A processor is in communication with the magnetic sensors. The processor is programmed to compute, based on signals generated by at least three of the sensors, the magnitude of a vector oriented in a direction substantially coincident with an inclination direction of a magnetic field in which the sensor is located.

  • Patent number: 6672169
    Abstract: A performance measuring system for a rotating shaft comprises a first annular support assembly to be coupled adjacent to a first end of a rotating shaft inwardly of associated shaft bearings. A second annular support assembly is to be coupled adjacent to a second end of a rotating shaft inwardly of associated shaft bearings. A third annular support assembly is to be coupled to the rotating shaft between the first and second support assemblies. A laser source is mounted on the first annular support assembly. A laser detector is mounted on the second annular support assembly. First and second magnetic sensors for detecting the Earth's magnetic field are mounted respectively on the first and second annular support assemblies. An accelerometer is mounted on the third annular support assembly for generating a fourth detection signal.

  • Patent number: 5443428
    Abstract: A gearless mechanical transmission includes a housing which supports a high-speed shaft and a low-speed shaft along a main rotational axis. The housing also includes a precession link therein fixed for rotation about the high-speed shaft at an angle skewed with regard to the main rotational axis. A first cam surface is associated with the housing, a second cam surface with the low-speed shaft and a third and fourth cam surface with a precession link. Cam follower elements include rollers which establish rolling contact between the first and third and second and fourth cams respectively.
