Patent number: 9273672Abstract: A solar energy collector utilizes one or more Fresnel lenses supported above a prepared surface for focusing sunlight at one or more sun ray spots. One or more tracking tables sense and track, during the course of the day, the movement of associated ones of the sun ray spots. Curved Fresnel lenses produce sun ray spots focused an offset distance above associated ones of one or more tracking tables, depending upon the sun's position. The sun ray spots may be forced to lie on the one or more tracking tables by moving an associated tracking table upward a distance equal to the offset distance. One or more wheel-equipped Stirling engines are positioned on the prepared surface and are conventionally controlled for tracking movement in concert with an associated sun ray spot.Type: GrantFiled: May 19, 2014Date of Patent: March 1, 2016Inventor: Fernando Ramon Martin-Lopez

Patent number: 8509579Abstract: A multiplicity of Fresnel lenses are attached to tubular branches of a tree-like support structure. Fiber optic bundles are connected to the Fresnel lenses and routed inside the tubular branches and collected as a larger fiber optic bundle inside a main trunk structure to which each of the branches is connected. The larger fiber optic bundle may be connected to a remotely located power generating plant or other processing facility via a fiber optic transmission network. A domed solar energy collector includes an outer dome and one or more inner domes concentrically nested therewith, one or more Fresnel lenses being positioned on the hemispherical surface of each of the outer and inner domes to thereby multiply the solar energy focused through each of the domes to a collection area within the innermost dome.Type: GrantFiled: March 28, 2012Date of Patent: August 13, 2013Inventor: Fernando Ramon Martin-Lopez

Patent number: 7157809Abstract: A method and circuits for improving the inductive DC converter delivery of regulated current into the load(s), where the inductive DC converter provides the output voltage to an ensemble consisting of the load(s) and a current source or a current source circuit connected in series with the load. The load current is controlled by the current source or the current source circuit in series with the load and not by the inductive DC converter, which only provides the voltage and power required at the output, without directly controlling the load current. The inductive DC converter can operate under much more relaxed specs, while the load current regulation is much tighter, being current source controlled.Type: GrantFiled: September 12, 2002Date of Patent: January 2, 2007Assignee: Toko, Inc.Inventors: Gabe C. Gavrila, Fernando Ramon Martin-Lopez

Patent number: 6993467Abstract: An offline trim circuit includes one or more irreversible trim elements, such as fuses, for example, used for setting electrical parameters to desired values. Associated circuitry is employed to verify the effect of trimming, prior to permanently setting trim bit values, permitting the optimal definition of the trim bit sequence and completely eliminating guesswork from the trimming procedure.Type: GrantFiled: December 5, 2000Date of Patent: January 31, 2006Assignee: Toko, Inc.Inventors: Gabe C.
