  • Patent number: 6633286
    Abstract: The present invention is a method and apparatus for providing a control system that controls at least one of a plurality of display units. In one embodiment, the control system includes a remote control circuit capable of activating a remote signal for moving the display unit between one of a first, a second and a third positions and another one of the first, the second and the third positions. The control system further includes a local display unit movement control circuit coupled to the display unit, and a transmitter coupled to the local display unit movement control circuit. The transmitter is configured to transmit a light beam capable of being reflected from a reflective surface near the transmitter to make a reflected light beam, and a receiver coupled to the local display unit movement control circuit.

  • Patent number: 6445573
    Abstract: An apparatus is described which includes a frame, a video monitor display mounted to the frame, a torque shaft coupled to the frame such that rotation of the torque shaft causes the frame to pivot along a predetermined arc. The apparatus further involves engaging to the torque shaft to impart rotational motion to the torque shaft, a releasable cam follower slidably disposed on the cam shaft and a spring mounted on the cam shaft exerting a spring bias force directed toward the cam so as to cause rotational motion of the cam.

  • Patent number: 5910814
    Abstract: An in-flight entertainment system includes several liquid crystal display (LCD) retract units mountable in a passenger service unit of aircraft. Each of the LCD retract units includes an input connector and an output connector arranged such that signals provided to the input connector appear at the output connector. A system control unit (SCU) is also provided. The SCU is configurable to provide video, power and control signals independently to the input connector of each of the LCD retract units and is also configurable to provide video, power and control signals to the input connector of only a first of the LCD retract units. In the second configuration, the input and output connectors of successive LCD retract units are connected in a daisy chain fashion such that the same signals are provided to each of the LCD retract units. In another aspect of the present invention, each of the plurality of LCD retract units includes status communications bus electronics such as RS-485.

  • Patent number: 5636055
    Abstract: A screen assembly that includes a screen material which is bonded to a thin metal substrate. The substrate is typically a solid 1/16 inch thick sheet of aluminum that is both light weight and strong. The bonded screen/substrate subassembly is mounted to an flip panel frame which is pivotally connected to an outer frame. To increase the rigidity of the substrate, the edges of the screen subassembly are located within a channel of the flip panel frame and held in place by a flexible foam cord that is pressed between the subassembly and the frame. The outer frame is pivotally connected to a stationary frame that is mounted to a structure, such as the wall of an aircraft passenger compartment. To display images on the screen, the outer frame is rotated away from the wall and the flip panel frame is flipped around to expose the screen to the passenger compartment.
