  • Opto-electric/hydraulic servoactuation
    Patent number: 6170525
    Abstract: A method for optical signaling for electrical switch control, and in addition, optical powering of the electrohydraulic servovalve by means of opto-electric conversion using solar cells with a battery backup and dual redundancy for reliability. Optical power sources are e.g., laser diode, LED, or high intensity lamp.
    Type: Grant

  • Crack growth measurement network with primary and shunt optical fibers
    Patent number: 5142141
    Abstract: A fiber optic crack propagation measurement apparatus including an input optical fiber for receiving light energy and an output optical fiber connected to deliver light energy to a detector is disclosed. A plurality of shunt optical fibers are connected in parallel between the input and output optical fibers. The input optical fibers, output optical fibers and shunt optical fibers are secured to a structure in which stresses are expected to cause the advancement of a crack. As the crack grows, individual shunt fibers are broken, reducing the amount of light energy delivered to the detector. Detector signals are generated indicative of the light energy received thereby to report the advancement of the crack. In one embodiment, wavelength division multiplexing techniques are employed so that multiple crack measuring units can be monitored over a single monitoring optical fiber.

  • Aircraft signal distribution system
    Patent number: 5140451
    Abstract: An aircraft signal distribution system communicates electrical signals between a first station in an aircraft and a second station in the aircraft. The two stations are connected by at least partially redundant optical cables which can transmit signals between the two stations within two or three optical spectral windows. By wavelength division multiplexing (WDM), the signals to be communicated can be placed on independent, closely spaced spectral intervals within the spectral windows. The signals which are transmitted through the cables to a station are converted back to electrical signals for use by electrical devices at or near that station.
