  • Patent number: 5982550
    Abstract: The present invention provides a secondary lens between the display lens and the vacuum florescent display. Both the lenses have an index of refraction greater than 1 which results in a momentary change in the viewing angle while the light passes through each lens. Since two lenses are used, the overall effective lens thickness for effective light shifting is increased while the cross sectional thickness of each lens remains uniform. Preferably, each lens is made of a polycarbonate material and has an index of refraction of 1.59. In another aspect of the present invention, the display lens is constructed of a smoke material and the secondary lens is clear.

  • Patent number: 5584381
    Abstract: Rocker buttons for devices such as automotive audio systems are mounted in escutcheons of the audio systems by using rocker frame members. Light dams, unitary with the rocker frame members shield LEDs used to illuminate indicia in the rocker buttons so that the light is not transmitted through gaps between the rocker buttons and the edges of openings through the escutcheons which receive the rocker buttons. Trunions extend laterally from the rocker buttons and are received within bearings formed by grooves in the escutcheons. In accordance with one embodiment of the invention, the rocker frames retain trunions in the bearings and in accordance with another embodiment of the invention peripheral display lenses overlie the trunions to hold the trunions in the bearings.

  • Patent number: 5560475
    Abstract: Rocker buttons for devices such as automotive audio systems are mounted in escutcheons of the audio systems by using rocker frame members. Light dams, unitary with the rocker frame members shield lamps used to illuminate indicia in the rocker buttons so that the light is not transmitted through gaps between the rocker buttons and the edges of openings through the escutcheons which receive the rocker buttons. Trunions extend laterally from the rocker buttons and are received within bearings formed by grooves in the escutcheons. In accordance with a preferred embodiment of the invention, the rocker frames retain trunions in the bearings and in accordance with another embodiment of the invention peripheral display lenses overlie the trunions to hold the trunions in the bearings.
