| 20100265628 | Redundant Power Supply with a Switchable, Linear Voltage Regulator - A system is provided that effectively obviates shortcomings of conventional, diode-ORed, redundant power supply systems by forcing a primary power source to provide power to the system load most the time, even when the primary source provides a lower voltage than that of a secondary power source. This preferential selection of the lower-voltage primary is achieved by interposing a power switching unit between the secondary power source and the ORing diode in front of the load. The power switching unit of the illustrative embodiment comprises a voltage regulator that is regulated at a first voltage level, which is lower than the nominal output voltage level provided by the primary power source. Meanwhile, the primary power source is able to charge the secondary power source, which is a battery in the illustrative embodiment, so that the secondary power source can provide power to the load when the primary power source is either interrupted or falls below the first voltage level. | 10-21-2010 |

| 20120065813 | SYSTEM AND METHOD FOR COMMAND AND DATA HANDLING IN SPACE FLIGHT ELECTRONICS - Disclosed herein are systems, methods, and non-transitory computer-readable storage media for controlling hardware on a remote spacecraft. A system practicing the method first identifies a piece of hardware on a remote spacecraft and a desired action for the piece of hardware and generates a command packet configured to instruct the piece of hardware to perform the desired action. The system then generates a container packet for transmission to the remote spacecraft and embeds the command packet within the container packet such that the remote spacecraft decodes the embedded packet to cause the piece of hardware to perform the desired action. Then the system can transmit the embedded packet to the remote spacecraft. Also disclosed herein is a robust, fault-tolerant memory module having strings of memory modules configured with a correction module to detect and correct errors. The memory module can maintain high reliability against severe radiation, mechanical, and thermal effects. | 03-15-2012 |

| 20100170526 | Interlocking process of V-shaped tapered flare-out synthetic eyelashes - A method to apply a V-shaped eyelash having four symmetric tapered strands attached at the mounting portion to natural eyelash's hair. The V-shaped eyelash has two strands on each side. The V flare corresponds to an angle can be less than or equal to 160° degrees. The thickness of each strand can be 0.10 mm to 0.30 mm thick at the base and tapered at the tips. The lengths can be from 7 mm to 17 mm giving the illusion of a natural long, beautiful and luscious eyelash. Because the eyelash extension is a V shape with the two strands on each side, the eyelash can distribute weight evenly on each side. The natural hair strand as the holder at center also making the eyelash extensions last longer. The eyelashes are made from synthetic fiber which is crimp free and can be permed to a C, and J curl. | 07-08-2010 |
