Patent application number | Description | Published |
20090197435 | PRINTED CIRCUIT BOARD DIRECT CONNECTION AND METHOD OF FORMING THE SAME - A system for directly connecting multiple printed circuit boards (PCB) circuits without the need for peripheral connectors. Multiple PCBs are electrically and mechanically interfaced with one or more plated holes or tabs on at least one first PCB and one or more plated tabs or holes on at least one second PCB. The plated tab(s)/hole(s) from said second PCB mate with the corresponding plated tab(s)/hole(s) from said first PCB to form a mechanical and electrical interconnect. | 08-06-2009 |
20090315484 | WIDE VOLTAGE, HIGH EFFICIENCY LED DRIVER CIRCUIT - An electrical circuit and method for driving light emitting diodes with a constant current via a high efficiency DC-DC converter controlled by a digital controller through pulse width modulation (PWM). | 12-24-2009 |
20100019829 | TURN ON-OFF POWER CIRCUIT FOR DIGITAL SYSTEMS - A turn-on circuit that is used to provide power to a system or other circuit when activated. The circuit is activated through depression of a momentary button or other similar device. The circuit is deactivated by a separate digital signal from said system or said other circuit and when deactivated no longer provides power to the system. | 01-28-2010 |
20100039072 | EQUALIZING METHOD AND CIRCUIT FOR ULTRACAPACITORS - An equalizing method for ultracapacitor cell packs and/or series connected ultracapacitors. | 02-18-2010 |
20100075513 | ORIENTATIONLESS SPRING PROBE RECEPTACLE ASSEMBLY - An electrical connector assembly for establishing an electrical connection (for signal or current transfer) between two circuits or wiring assemblies. | 03-25-2010 |
20110057615 | UNIVERSAL POWER INTERFACE BUS - A circuit and communication method for charging and/or discharging electrical energy storage devices (e.g., one or more cells of ultracapacitors, one or more cells of batteries, one or more cells of ultracapacitors and batteries). | 03-10-2011 |
