20090316450 | POWER SUPPLY DEVICE WITH SYSTEM SWITCH CIRCUIT - A power supply device with a system switch circuit includes a primary power system, a stationary power system and a power management unit. The power management unit is triggered by a remote ON/OFF signal to generate a bias voltage power for turning on the primary power system after obtaining a stationary power. The system switch circuit is triggered by the remote ON/OFF signal to interrupt the stationary power system from obtaining an electric power path of an input power or a reference frequency signal to interrupt the stationary power, and triggered by the remote ON/OFF signal again to conduct the stationary power system to obtain the electric power path of the input power or the reference frequency signal to generate the stationary power, so as to achieve the effects of reducing a power loss as well as maintaining a normal operation of the power supply device. | 12-24-2009 |
20100110737 | MULTI-OUTPUT POWER SUPPLY - A multi-output power supply includes a standby power system and a main power system. The main power system has a transformer and a rectification output circuit connecting to the transformer to generate first output power. The power supply further has an output time series judgment circuit and a plurality of voltage regulation units connecting respectively to the standby power system and the rectification output circuit. The output time series judgment circuit has a preset reference potential compared with the potential of the first output power to determine whether to output a feedback signal. Each voltage regulation unit is connected to the output time series judgment circuit to receive the feedback signal and be activated normally and determine a regulation time spot to synchronously regulate the first output power to second output power. Thus the time difference for delivering the first output power and the second output power can be regulated. | 05-06-2010 |

20100095453 | Sit/stand assistance device - A sit/stand assistance includes a seat, a frame, a lifting device, and a driving device. This lifting device has a fixed portion connected to the frame and a movable portion pivoted with the seat so as to move the seat up or down. The driving device includes a link, a power portion, and a working rod. One of the power portion and the working rod is pivoted with the link. The other one is pivoted with the frame. When the power portion pushes the working rod, the working rod extends out so as to make said seat moving up or tilting. Hence, it can assist a user from a seated position to a standing position. So, it matches a user's continuous sit-to-stand motion. Plus, it can be directly applied on an existing flush toilet. | 04-22-2010 |
