  • Method of creating a field electron emission material
    Patent number: 6969536
    Abstract: A field electron emission material is created by applying a silica precursor to graphite particles (11); processing the silica precursor to produce amorphous silica (12) which is doped and/or is heavily defective, and disposing the graphite particles (11) upon an electrically conductive surface (14) of a substrate (13) such that they are at least partially coated with the amorphous silica (12).

  • Trailer hitch mount for vehicle backup sensor
    Patent number: 6788190
    Abstract: An object detection system is mounted at the rear of a vehicle the trailer receiver for the vehicle. The object detection system warns the driver of the vehicle of persons or objects behind the vehicle, when the vehicle is moving backwards. The system emits microwaves rearwardly of the vehicle and senses microwave reflected from objects behind the vehicle. The microwave transceiver is mounted in the trailer receiver in place of the trailer ball that is normally mounted in the receiver.
