International Classification:

F21V 700

US Classification:

362307, 362240, 362245, 362347, 362309

Abstract:

A highly efficient luminaire. The luminaire includes a light source that emits light. The emitted light is redirected by a light transformer having a curved circular reflective interior surface, the reflective interior surface reflecting the light in a predetermined pattern. A substantial amount of light being may be reflected close to an axis coincident with a radial line defining a radius of the circular reflective interior surface. Additionally, a substantial amount of light may be reflected in a pattern with low divergency or parallel with an axis of the light transformer. The light is transmitted to the exterior of the luminaire by an optical window.

Filed:

Mar 19, 2004

Appl. No.:

10/805037

Inventors:

David Ruiz - Anaheim CA, US

International Classification:

G09G005/00

US Classification:

345156000

Abstract:

A cursor control device has an input signal reader adapted to read an input signal created by movement of a surface there across, and a signal processing component adapted to process the input signal from the reader and to communicate a corresponding signal to a controller that is directly proportional to the input signal. The device remains in a substantially constant position relative to an active hand of a person when the person is using the active hand to operate a second device.

Appl. No.:

13/661595

Inventors:

David M. Ruiz - Costa Mesa CA, US

Assignee:

CELLNOCK CORPORATION - Costa Mesa CA

International Classification:

H04W 4/20
H04W 88/02

US Classification:

455466, 4555751

Abstract:

A system for identifying presence of a visitor has a local device () to be activated by the visitor, connected to a remote device () via a communication link (). The remote device receives data from the local device such that a user with the remote device is notified of the visitor's presence at the local device, and can optionally communicate with the visitor and/or control the local device through the communication link.

Appl. No.:

7/090235

Inventors:

David M. Ruiz - Indio CA
Alvin S. Timmons - Santa Rosa CA

Assignee:

Union Oil Company of California - Los Angeles CA

International Classification:

B01D 5000

US Classification:

55276

Abstract:

Noise suppression and particle separation apparatus for flows of high pressure, high velocity, particle-laden, gaseous fluid, such as geothermal steam, comprises a gaseous fluid conduit that has axially installed around its discharge end a larger diameter, cylindrical inner expansion chamber having a number of flow-dividing fluid discharge openings at which fluid flow diffusing elements are connected for receiving and diffusing the flow of gaseous fluid from the apertures. A still-larger diameter, cylindrical noise suppression chamber is axially mounted around the inner chamber and flow diffusing elements. The diffusion elements increase the fluid flow noise frequency range and sound deadening material installed in the outer chamber absorbs noise in this higher frequency range so that the venting fluid noise level outside the apparatus is no more than about 95 dB. To enable fluid expansion, the fluid conduit diverges at its outlet end, the inner chamber has a diameter at least about twice that of the flow inlet conduit and the outer chamber has a diameter that is at least about twice that of the inner chamber. Flow direction and velocity changes in the apparatus cause the disengagement of particulates entrained in the fluid flow.

Assignee:

Physical Optics Corporation - Torrance CA

International Classification:

F21V 704

US Classification:

362551

Abstract:

Surface light assemblies are disclosed that are particularly useful as edge light assemblies for illuminating the outer boundaries of a deck of a ship or a heliport and as line-up light assemblies for illuminating a path on a surface such as a ship deck, a runway or the like. The light assembly includes a fiber optic cable connected to the bottom of a housing or enclosure which distributes light from a terminal end of the cable. The terminal end may include a transformer which produces a particular spread or cone of a light output pattern. Alternatively, a diffuser or optical element may be placed directly adjacent the terminal end of the cable or transformer which shapes, directs and homogenizes light emanating from the cable. The light assembly can include a durable glass window which protects the diffuser and cable and which can be adapted to filter out certain wavelengths of light producing a light output in a desired color. Such a construction is particularly useful for deck edge lighting.

International Classification:

G02B 604
F21V 800

US Classification:

385115

Abstract:

A remote light source lighting system is provided having an illuminator assembly including a housing. Held within the housing is a high intensity light source for providing light energy to a fiber optic cable bundle connected to the housing and facing the light source. The cable bundle includes a plurality of plastic optical fibers wherein at least one of the terminal ends of the bundle is formed by molding an optical quality resin around an optically transparent ferrule that binds the exposed ends of the optical fibers. The housing further includes a separate air plenum containing a blower. The blower produces a high velocity air stream directed precisely at the terminal end of the cable adjacent the light source to cool the terminal end.

International Classification:

F21V 2128

US Classification:

362281

Abstract:

An illuminator for a high energy remote lighting system includes a light source for generating light energy and a selectively positionable light output modifying apparatus having a plurality of light output modifying elements, each element corresponding to a predetermined position of at least a portion of the apparatus. At least some of the light output modifying elements of the apparatus are configured to filter light energy to provide either dimmed or colored light. The illuminator can be implemented in a system having a plurality of area control panels, each control panel generating a control signal indicative of a corresponding light characteristic, the illuminators each being coupled to a corresponding one of the area control panels to receive the control signal and to output a particular type of light in response thereto.
