Publication number: 20100212648Abstract: A firing frequency controller which includes a cylinder body, a piston assembly, and a unidirectional seal is provided. The cylinder body includes a first orifice, a second orifice and a third orifice, wherein the gas flux through the first orifice and the third orifice are inequality. The piston assembly disposed inside said cylinder body is repeatedly moved. The unidirectional seal is disposed at outside of the piston and adjacent to the inner wall of the cylinder body. The unidirectional seal is contacted with the cylinder body and is kept airtight while moved at one direction. The unidirectional seal is not contacted with the cylinder body and kept non-airtight while moved at another direction. Because of pressure difference, the velocity of piston assembly can be adjusted and then the firing frequency of toy gun can be controlled.Type: ApplicationFiled: June 15, 2009Publication date: August 26, 2010Inventor: Shu-Mei TSENG

Publication number: 20100212653Abstract: The present invention is directed to an apparatus and method for improving the total power output from a field of solar energy systems. The invention provides a field level tracker controller which calculates an improved positioning of individual solar energy systems and communicates those configurations to trackers in the field. An algorithm stored in the controller calculates the improved configuration for the solar energy systems based on factors such as solar movement, shade patterns generated by surrounding structures, and measured output of the energy systems. Improved positioning may include individual energy systems being directed to a stowed position to maximize the power output of the field as a whole.Type: ApplicationFiled: February 25, 2009Publication date: August 26, 2010Applicant: SolFocus, Inc.Inventor: Mark McDonald

Publication number: 20100212654Abstract: It includes at least one module with a concave reflecting mirror surface which concentrates the light radiation towards certain devices in order to then obtain electrical or other type of energy. It also includes means for orienting that mirror surface according to the position of the sun. It is characterised in principle in that each module comprises a thin lightweight laminar body with an arched structure which incorporates the concave mirror surface, this laminar body being associated with certain stiffening supports which stabilise and stiffen that arched structure in order to maintain this shape, said structure being supported on some ground with the interposition of guide means by which the arched structure at least tilts towards one side or the other depending on the light sensor or timer which activates a device that positions each module in real time with the required orientation according to the position of the sun.Type: ApplicationFiled: July 9, 2008Publication date: August 26, 2010Inventor: José Javier Alejo Trevijano
