Patent number: 7728219Abstract: A photovoltaic cell has electrodes, p- and n-junctions, and a heat sink. The heat sink is on a side of the cell opposite to the light-receiving side of the photovoltaic cell. The photovoltaic cell may also have heat-conducting channels within an interior of the photovoltaic cell that conduct heat from the interior of the photovoltaic cell to the heat sink. The heat sink can remove heat caused by light absorbed by the photovoltaic cell but not converted to electricity as well as heat generated by resistance to high current passing through electrodes of the photovoltaic cell. A module formed of such cells can exhibit greater energy conversion efficiency as a result of the ability to dissipate the heat. A method of making a solar cell or module involves e.g. laminating a heat sink to a photovoltaic cell as described above.Type: GrantFiled: April 20, 2007Date of Patent: June 1, 2010Assignee: Sunmodular, Inc.Inventor: Eugenia M.

Patent number: 7482888Abstract: A startup circuit 200 and method 700 is provided for quickly starting up a resonator based oscillator. Tunable oscillator 201 provides an impetus signal to oscillator 205 through capacitor 202. The impetus signal has a frequency that is an estimate of the resonant frequency of resonator 205. The circuit measures the frequency of oscillator 204 and the frequency of tunable oscillator 201. The circuit then adjusts the frequency of tunable oscillator 201 such that the frequency of the tunable oscillator is substantially equal to the resonant frequency of the resonator 205 and stores a data state necessary for the tunable oscillator 201 to generate a signal with this target frequency in the future. During an ensuing startup cycle the stored data state causes the impetus signal delivered by tunable oscillator 202 to be substantially equal to the target frequency of oscillator 204 which improves startup performance.Type: GrantFiled: July 12, 2007Date of Patent: January 27, 2009Assignee: ZeroG Wireless, Inc.Inventor: Bendik Kleveland

Patent number: 7474159Abstract: A calibration circuit (17) for calibrating a frequency synthesizer (10) having a voltage-controlled oscillator (VCO) (15) with a plurality of switched-capacitor arrays (CA1-CAn). The calibration circuit (17) counts a predetermined number of periods of the reference-clock signal (ref_clk) and divide-clock signal (div_clk) of the frequency synthesizer using a fast clock signal (fastclk). The fast-clock signal (fastclk) has a frequency greater than either the reference-clock signal (ref_clk) or the divide-clock signal (div_clk), enabling significantly faster calibration of the frequency synthesizer (10) than would be possible using the reference-clock signal (ref_clk). The calibration circuit (17) compares the count of the periods of the reference-clock signal (ref_clk) and the divide-clock signal (div_clk) and varies the tank signal of the VCO (VCO_tank_setting) until the count of the periods is substantially equal.Type: GrantFiled: May 8, 2007Date of Patent: January 6, 2009Assignee: ZeroG Wireless, Inc.Inventors: Stanley Wang, Thomas H.
