| 20120091811 | Uninterruptible Power Supply Systems and Methods for Communications Systems - An uninterruptible power supply for supply electrical power to a load, comprises a connection to a primary source for supplying primary power, a battery system for storing battery power, an inverter, and a controller. The controller controls the inverter to operate in a first mode, a second mode, and in a third mode. In the first mode, power is supplied to the primary load and the battery system based on primary power. In the second mode, power is supplied to the primary load based on battery power. In the third mode, power is supplied to the primary source based on battery power. | 04-19-2012 |
| 20110198932 | Ferroresonant transformer for use in uninterruptible power supplies - A ferroresonant transformer comprises a core, a main shunt, first windings, second windings, and third windings. The main shunt arranged relative to the core to define a primary side and a secondary side of the ferroresonant transformer. The first windings are arranged on the primary side of the ferroresonant transformer and are operatively connected to the primary power source. The second windings are arranged on the secondary side of the ferroresonant transformer and are operatively connected to the secondary power source. The third windings are arranged on the secondary side of the ferroresonant transformer and are operatively connected to the resonant capacitor. When a primary signal is present on the first windings, a first output signal is present on at least a portion of the third windings. When a secondary power is present on the second windings, a second output signal is present on at least a portion of the third windings. | 08-18-2011 |
| 20100275968 | SOLAR POWER SYSTEMS OPTIMIZED FOR USE IN COLD WEATHER CONDITIONS - A solar power system for supplying electrical energy to a load based on solar energy comprising at least one solar panel, a power supply, and at least one mode select switch. The at least one solar panel comprises at least one solar cell. The at least one mode select switch is operatively connected to the at least one solar panel, the power supply, and the load. The at least one mode select switch is operable in a first mode and in a second mode. In the first mode, the at least one solar cell is capable of supplying electrical energy to the load. In the second mode, the power supply supplies electrical energy to the at least one solar cell such that the at least one solar cell generates heat. | 11-04-2010 |
| 20100141973 | HIGH DENSITY, HIGH INTENSITY INK FORMULATION AND METHOD FOR PRINTING HIGH INTENSITY COLORS - A high intensity ink solution includes a letdown varnish of about 50% to 58% by weight, a dispersion oil of about 8% to 15% by weight, a pigment about 18% to 25% by weight, a wax compound of about 4% to 10% by weight, and a drier compound of about 1%-3% by weight. A method of producing high intensity color prints includes generating a color space and placing the color space in a CMYK file, generating a color proof, then generating at least four printing plates, and configuring a printer to print specific color densities to accurately match the color proof. Densities of pigments, such as yellow, magenta, cyan, and black are included in the inks, creating color which is perceived more strongly with less dots per area than currently available inks. | 06-10-2010 |
| 20090189574 | SIMPLIFIED MAXIMUM POWER POINT CONTROL UTILIZING THE PV ARRAY VOLTAGE AT THE MAXIMUM POWER POINT - A converter system adapted to be connected between a photovoltaic power source and a load comprises a converter circuit, a control circuit, and a PWM generator circuit. The converter circuit is operatively connected to transfer energy from the photovoltaic power source to the load. The control circuit generates a raw control signal based on at least a voltage generated by the photovoltaic power source. The PWM generator circuit is operatively connected to the converter circuit and generates a PWM switch signal based on the raw control signal. The converter circuit transfers energy from the photovoltaic power source to the load based on the PWM switch signal. | 07-30-2009 |
