| 20090142936 | METHOD OF FORMING GATED, SELF-ALIGNED MICRO-STRUCTURES AND NANO-STRUCTURES - Methods of forming a gated, self-aligned nano-structures for electron extraction are disclosed. One method of forming the nano-structure comprises irradiating a first surface of a thermally conductive laminate to melt an area across the first surface of the laminate. The laminate comprises a thermally conductive film and a patterned layer disposed on the first surface of the film. The patterned layer has a pattern formed therethrough, defining the area for melting. The film is insulated at a second surface thereof to provide two-dimensional heat transfer laterally in plane of the film. The liquid density of the film is greater than the solid density thereof. The method further comprises cooling the area inwardly from the periphery thereof to form the nano-structure having an apical nano-tip for electron emission centered in an electrically isolated aperture that serves as a gate electrode to control electron extraction in a gated field emitter device. | 06-04-2009 |

| 20100127570 | Systems and Methods for Using a Power Converter for Transmission of Data over the Power Feed - Apparatuses and methods include a photovoltaic energy production unit to generate electricity. A local management unit is coupled between the photovoltaic energy production unit and a connection of energy production units forming a string bus. The local management unit includes a controller and switching circuitry. The controller provide a control for the switching circuitry to deliver electrical energy to the string bus. A communication transmission modulator is associated with the local management unit. The communication transmission modulator modulates the control with data to be transmitted from the local management unit over the string bus. | 05-27-2010 |
| 20100327807 | Enhanced Battery Storage and Recovery Energy Systems - Systems and methods are herein disclosed for efficiently and cost-effectively balancing the voltages across batteries and/or cells in an energy storage system. A controller monitors the battery voltages and instructs regulator circuits to balance voltages between any batteries or sets of batteries having imbalanced voltages. Regulator circuits implementing a modified Ćuk converter can be utilized. Regulator circuits can have two capacitive circuits, one inductive circuit, and two switches. Two capacitors, an inductor, and two field effect transistors can be used in each regulator circuit. | 12-30-2010 |
| 20110050190 | Systems and Methods for Enhanced Efficiency Auxiliary Power Supply Module - Provided is a power supply for use in a solar electric production system, including: a first stage having an input connected to a voltage from a photovoltaic panel and an output providing a first voltage different from the voltage from the photovoltaic panel; and a second stage connected to the output of the first stage, the second stage supplying power at a second voltage to a micro-controller, where the output of the first stage is turned on and stable for a period of time before the second stage is turned on to supply the power at the second voltage to the micro-controller. | 03-03-2011 |
| 20110079263 | Systems and Methods to Provide Enhanced Diode Bypass Paths - Systems and methods are herein disclosed for efficiently allowing current to bypass a group of solar cells having one or more malfunctioning or shaded solar cells without overwhelming a bypass diode. This can be done using a switch (e.g., a MOSFET) connected in parallel with the bypass diode. By turning the switch on and off, a majority of the bypass current can be routed through the switch, which is configured to handle larger currents than the bypass diode is designed for, leaving only a minority of the current to pass through the bypass diode. | 04-07-2011 |
