An electronic circuit within the caisson controls operation of the beacon. The caisson material acts as a heat sink for the solar cells, and insulation is provided below the cells to further protect the electronic components.Type: GrantFiled: September 29, 1986Date of Patent: July 26, 1988Inventors: Frederic Pagnol, Claude Ratti

Patent number: 4751413Abstract: A solar energy motor comprises a plurality of photovoltaic elements, such as solar cells, and armature coils unistructurally secured to a rotatable axis. The photovoltaic elements and the armature coils are electrically connected such that DC electromotive forces generated sequentially in the photovoltaic elements on which light beams are made incident are applied to the armature coils. Currents thus generated in the armature coils produce a torque in the presence of magnets.Type: GrantFiled: April 11, 1986Date of Patent: June 14, 1988Assignee: Sharp Kabushiki KaishaInventor: Hideo Izawa

Patent number: 4744430Abstract: A solar cell array is disclosed having a support structure, cover, and mechanically joined solar cell panels. Each panel, or group of panels, is electrically connected across a separate battery and a diode is provided to provide separate charging of each battery and to prevent flow of current to the solar cells from the batteries.Type: GrantFiled: August 14, 1987Date of Patent: May 17, 1988Inventor: Thomas R. McCoy

Patent number: 4740431Abstract: An integrated solar cell and battery are described, together with a process of making the same. The integrated solar cell and battery are made by employing thin film deposition techniques on a substrate. Preferably first, a thin film solar cell is deposited on the substrate, as for example, by sputtering. This step is immediately followed by the deposition of a thin film battery, either onto the previously deposited thin film solar cell, or onto the back side of the substrate. The deposition process lends itself to automated production. The process includes the thin film deposition of series-connected arrays forming different types of integrated solar cells and batteries, depending on their electrical connections so as to vary the respective current and voltage characteristics of the resultant integrated units.Type: GrantFiled: December 22, 1986Date of Patent: April 26, 1988Assignee: Spice CorporationInventor: Roger G. Little

Patent number: 4726044Abstract: A ballpoint pen of conventional size and shape has a movable ball point that is pressed upwardly in the direction of the housing of the pen when a mark is made. Means is provided for normally biasing the ballpoint outwardly of the housing. However, when the ballpoint is pressed against a writing surface, the refill cartridge having the ball at the lower end thereof is moved upwardly to close a normally open switch which connects a solar cell array in circuit with an electronic counter that counts each time the switch is closed. Controlled by the counter is a liquid crystal display that visually indicates the total number of counts. A second switch is actuated by gravity to reset or clear the counter in preparation for counting a succeeding group of marks.Type: GrantFiled: October 20, 1986Date of Patent: February 16, 1988Assignee: Fred P. PernaInventors: Fred P. Perna, Stuart R. Peterson

Patent number: 4718185Abstract: A modular solar generating system is disclosed. The system includes a plurality of self-contained solar modules which are interconnectedly disposed in an array about the perimeter of a rigid framework housing a sign, light, or other load means necessitating electrical power during the night time hours. The modules themselves consist of a photovoltaic plate sandwiched between two suitable cover plates, including in this arrangement one or more continuous conductors. The modules are linked together by way of male and female plug connectors whereby the array may then be electrically connected to a battery. When the modular system is arranged in this fashion and exposed to incident sunlight for an appropriate period of time, power may be provided to a sign, light or other electrical apparatus for nighttime use.Type: GrantFiled: November 7, 1986Date of Patent: January 12, 1988Assignee: Solar Signage, Inc.Inventors: Kevin L. Conlin, Michael P. Cantrell

Patent number: 4717790Abstract: A contoured solar generator whose solar cells and their associated electrical terminals and connecting lines are embedded in a laminate including at least the solar cells, an elastic thermosetting adhesive foil and a glass pane. To adapt the solar generator to a given external contour or to fit it into a given contour, the solar generator is configured as a curved laminate including at least one-dimensionally bent solar cells.Type: GrantFiled: October 31, 1986Date of Patent: January 5, 1988Assignee: Licentia Patent-Verwaltungs-GmbHInventor: Hans Gochermann
