Patents by Inventor William G. Linzey

William G. Linzey 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).

  • Wire test method and apparatus
    Patent number: 6812712
    Abstract: A wire testing method and apparatus test wire in-situ in a rigidly installed state, such as an aircraft. An apparatus for rapidly switching the excitation voltage and ground compensates for stray currents. The apparatus outputs a stray current signal, a detected signal, and a difference signal indicative of a measurement with stray current signal removed.

  • Kit-based wire evaluation
    Patent number: 6810728
    Abstract: To provide an evaluation of the remaining life (level of insulation degradation) of wire in an installation, a kit-based approach avoids the need for technical personnel to visit a customer location. The kit includes equipment and instructions for selecting specimens for removal, capturing pre-removal information, removing the specimens, and sending the specimens for evaluation. A round form padded with protective material simplifies packing of the specimens while avoiding customer damage to the specimens. Accelerated aging testing and comparison between results for specimens from zones particularly susceptible to aging and one or more reference specimens permits an evaluation of remaining wire life.

  • WIRE TEST METHOD AND APPARATUS
    Publication number: 20040124849
    Abstract: A wire testing method and apparatus tests wire (30) in-situ in a rigidly installed state, such as an aircraft (100). Stray currents are compensated by an apparatus for rapidly switching the excitation voltage and ground. The apparatus outputs a stray current signal (721), a detected current signal (731), and a difference signal (830) indicative of a measurement with the stray current signal removed.

  • Wire degradation testing system
    Patent number: 6225811
    Abstract: A part of a wire is tested, in situ, for degradation. The part of the wire is optionally enclosed in a jacket. A conductive medium is disposed on the wire. A test unit has a test elements in contact with the conductor of the wire and with the conductive medium. An attempt is made to induce a current along a path from the test unit, through the conductor, through the conductive medium, and back to the test unit. If a current is induced, degradation is detected. The test unit receives a cable of wires, and a selector switch of the test unit electrically couples a voltage source to selected elements of the cable in turn. Wires are tested in situ in an aircraft or other restrictive location.
