LED device for wide beam generation
ActiveUS7674018B2Easy to combineReduce discontinuityPlanar light sourcesMechanical apparatusSurface patternWide beam
An apparatus and method is characterized by providing an optical transfer function between a predetermined illuminated surface pattern, such as a street light pattern, and a predetermined energy distribution pattern of a light source, such as that from an LED. A lens is formed having a shape defined by the optical transfer function. The optical transfer function is derived by generating an energy distribution pattern using the predetermined energy distribution pattern of the light source. Then the projection of the energy distribution pattern onto the illuminated surface is generated. The projection is then compared to the predetermined illuminated surface pattern to determine if it acceptably matches. The process continues reiteratively until an acceptable match is achieved. Alternatively, the lens shape is numerically or analytically determined by a functional relationship between the shape and the predetermined illuminated surface pattern and predetermined energy distribution pattern of a light source as inputs.

InactiveUS7366463B1Frequency-division multiplex detailsBroadcast transmission systemsCommunications systemSignal on
A radio signal relay device such as satellite is used to cover several relatively small geographical regions with relatively narrow beams as well as a relatively large geographical region with a single beam. This relatively wide beam permits legacy equipment to be used. A transmitting device in a beam transmits a signal to the relay device, which in turn retransmits the signal to a receiving device. The transmitting devices, relay device, and receiving devices synchronize communication by using a particular mode of communication which includes a band of carrier frequencies and a protocol. In addition to communicating like mode signals from a transmitter to a receiver, the relay device may be used in a dual mode communication system to translate signals from the one mode to another. A translator may direct a transmitter to modulate a signal on a different carrier frequency, convert one protocol into another protocol, or both.

LED Devices for Offset Wide Beam Generation
A light source is combined with an optic and a reflector. Light incident onto to the reflector is reflected with a single reflection. The reflector occupies a portion of a solid angle around the light source to the exclusion of the optic at least with respect to any optical function. The reflector directly receives a second portion of light. The optic occupies substantially all of the remaining portion of the predetermined solid angle to directly receive a first portion of light from the light source. A reflected beam from the reflector is reflected into a predetermined reflection pattern. The inner and / or outer surface of the optic is shaped to refract or direct light which is directly transmitted into the optic from the light source from a first portion of light and / or reflected into the optic from the reflector from the reflected beam into a predetermined beam.

Luminaire with distributed LED sources
A wide beam angle (diffuse) luminaire with an efficient multi-source radiative emitter array. Embodiments of the luminaire utilize one or more LEDs disposed around a perimeter of a protective casing. The LEDs are angled to emit into an internal cavity defined by the inner surface of the casing. The placement of the LEDs around the perimeter of the device reduces self-blocking and facilitates heat transfer from the LEDs through the casing or another heat sink and into the ambient. Light impinges on the inner surface and is redirected as useful emission. A diffuse reflective coating may be deposited on the inner surface to mix the light before it is emitted.

Amphibious recreational vehicle
InactiveUS6840825B1Easy to planEliminate parasite dragAmphibious vehiclesVehicle with living accommodationNacelleWater vapor
An amphibious recreational vehicle (motorhome, trailer, SUV, and the like) of conventional RV height, width, and length restricted dimensions necessary to travel on highways and roads, and which upon entering the water, the bottom of the vehicle expands outwardly and upwardly to form a fast planing, wide-beam, ground effects cathedral type double-tunnel hull. The hull makes use of a dynamic air cushion to augment the planing of the hulls, owing to the ground effect created by compression of the ram air stream (and water vapor) rushing through the two tapered tunnels separating the three hulls. The wheels of the vehicle are simultaneously raised out of the water to eliminate parasite drag. The resultant hull is substantially wider than the cabin, providing substantial ocean-going stability for the craft. The folded elements incorporated within the cabin rooftop, raise upward to form a traditional yacht flying bridge, complete with a windshield, steering station, seating, mast, and safety rails. The resultant watercraft closely approximates the off-shore speed, seaworthiness, performance, stability, cabin space, main deck space, and elevated flying bridge deck attributes of conventional yachts. And when on land, the craft is a fully functioning traditional recreational vehicle suited for fast highway travel, driving about towns, staying in RV parks, and camping in the wilderness. This amphibious recreational vehicle is an interrelated component divided from the inventor's previous Comprehensive Vehicle Construction And Hybrid Electric Drive System application.
