The measuring means determines the optical aperture of the inflatable cushion by measuring the quantity of illuminating energy collected by the electromagnetic energy receiving device when the electromagnetic energy emitting device illuminates the interior of the inflatable cushion.Type: GrantFiled: June 11, 1998Date of Patent: July 27, 1999Assignee: Gaymar Industries, Inc.Inventors: Michael Rechin, John K.

Patent number: 5899557Abstract: A Multi-Source electronic lighting device for use as a signal or illuminator. Light is created by a plurality light emitting diode elements which are encapsulated in a light transmitting medium. A curved cylindrical lens is contoured to cooperate with the location of the light emitting diode elements to create a composite light beam with a controlled beam pattern which is elongated in a defined plane. The intensity of the projected light beam is maximized through the efficient collection of created light.Type: GrantFiled: August 11, 1994Date of Patent: May 4, 1999Inventor: Kevin McDermott

Patent number: 5898530Abstract: A radiation apparatus comprising a radiation source and a filter arranged in an optical path, said filter comprising two transparent filter discs which are arranged substantially in plane-parallel fashion relative to each other and which are held with their surrounding edges in a frame made of a material of good heat conduction, the filter discs and the frame defining a closed cavity which has provided therein a medium for selectively influencing the radiation spectrum. The frame is divided substantially in a direction transverse to the filter axis into first and second frame halves in such a manner that the one filter disc is arranged on the first frame half at the side facing the cavity and the other filter disc is arranged on the second frame half at the side facing the cavity.Type: GrantFiled: April 19, 1995Date of Patent: April 27, 1999Assignee: Maxs AGInventor: Werner Braun

Patent number: 5845984Abstract: A device for repelling cats from areas where their presence is unwanted comprised a tranparent clylindrical shaped canister capable of light transmission therethrough which can optionally be mounted upon a center support having various attachments thereto for placement of the device in indoor or out door areas. An optional communication light source causes the canister to glow and transmit light when in a darkened area.Type: GrantFiled: August 6, 1996Date of Patent: December 8, 1998Inventor: Lawrence Bonilla

Patent number: 5803580Abstract: A decorative light is disclosed. It includes a hollow base seat having a bulb seat on bottom portion for a bulb to fit in. The bulb is surrounded by a thermally insulated sheet which is spaced from the base seat and the bulb by a certain distance. A top end of the base seat is formed with a through hole in which a container is fitted. The container contains a liquid inside, which is dyed into a predetermined color and mixed with a plurality of polished plates. In use, the bulb radiates light and heat to the container to stir up the liquid, so that the polished plates are rolled to reflect the light and create a dynamic flickering effect.Type: GrantFiled: August 22, 1997Date of Patent: September 8, 1998Inventor: Yang-Hsu Tseng

Patent number: 5803729Abstract: A light curing gun for dental filling material includes a conical light concentrator element and a water filed chamber between the light source and the concentrator element. The water increases the collection of light as well as cooling the concentrator and filtering out light in the infrared portion of the spectrum. A water cooling jacket may also be provided around the light source and may be coupled to the water window so that water can be circulated through both the window and the water jacket.Type: GrantFiled: July 17, 1996Date of Patent: September 8, 1998Assignee: Efraim TsimermanInventor: Efraim Tsimerman

Patent number: 5758956Abstract: A high intensity light projector for stage, architectural and similar applications includes a controllable image quality projection gate providing advanced visual effects. The projection gate, capable of selectively scattering or transmitting incident light, may be constructed of any array of scattering liquid crystal material in combination with infrared and ultraviolet reduction means which provide in the high intensity beam, a stable thermal environment by minimizing the absorption of light by the projection gate. Additional thermal efficiency is provided by supplemental cooling means. Color control is also provided in the form of dichroic filter wheels forming cooperating adjustable low, high and band width filters including saturation control. A color measuring feedback sensor is also provided. An intensity measuring feedback sensor controls a spatially-modulated, variable-density, reflectively-coated dimming wheel. A programmable gobo system has provisions for gobo selection, orientation, and rotation.Type: GrantFiled: June 7, 1995Date of Patent: June 2, 1998Assignee: Vari-Lite, Inc.Inventors: James M. Bornhorst, Richard W. Hutton, Richard K. Steele
