Abstract:
A power supply housing adapted to a redundant power module includes a casing, a separation member, two front plates and a back plate. The casing includes four side plates and an installation space defined by the side plates. The separation member divides the installation space into a first sub-space and a second sub-space, and includes two first baffles located in the first sub-space and two second baffles located in the second sub-space. The two first baffles define a first installation region for disposing a redundant power module, and the two second baffles define a second installation region for disposing the redundant power module. The front plates are disposed on one end of the installation space and define a placement opening, serving as an entrance of the first and the second installation region. The back plate is disposed on one end of the installation space not provided with the front plates.

Abstract:
An electric power system for transportation comprises an electric generator started up by an ignition signal, an electricity storage element and a power supply connected to the electric generator, the electricity storage element and the load. The power supply comprises a standby power supply unit, an operating power supply unit and a control unit connected to the electric generator. The control unit is provided with a first state allowing the standby power supply unit and the operating power supply unit to stop operation when the ignition signal is not detected, and a second state starting up the standby power supply unit so as to allow the standby power supply unit to supply electric power to the load and induce the load to emit an on-off signal to the operating power supply unit when the ignition signal is detected.
Abstract:
An inrush current recording module is installed in a power supply unit. The power supply unit has a front-stage power circuit and a back-stage power circuit. The front-stage power circuit includes a first ground terminal, and the back-stage power circuit includes a second ground terminal. The inrush current recording module includes a series circuit and a detection recording unit. The series circuit is formed by a capacitor and a resistor, and includes two ends thereof respectively connected to the first ground terminal and the second ground terminal. The detection recording unit detects the resistor to generate a voltage signal, compares the voltage signal with a voltage determination level, starts timing an inspection period when the voltage signal is greater than the voltage determination level, and records whether a current inrush current is harmful or harmless according to whether a power output signal is obtained within the inspection period.
Abstract:
A keyboard equipped with multipoint press positions comprises at least a baseboard, a keycap assembly and a command trigger assembly. The keycap assembly includes a support frame to hold a plurality of keycaps. The command trigger assembly includes a command circuit board and a plurality of elastic switches. The command circuit board includes a plurality of trigger portions corresponding to the keycaps and triggered by the keycaps, and at least one primary command circuit electrically connected to each trigger portion. The elastic switches are corresponding to and depressible by the keycaps to trigger the trigger portions. Each elastic switch includes a base and a primary movement portion, a first secondary movement portion and a second secondary movement portion that are respectively corresponding to a primary trigger switch and at least two secondary trigger switches of the trigger portions. The keyboard thus formed can provide higher press sensitivity.
Abstract:
A redundant power supply system providing rapid start of backup includes at least one primary power supply, at least one secondary power supply and a power integration panel. The secondary power supply includes a voltage regulation and energy saving element which has regulation potential after the secondary power supply being booted up. When the secondary power supply is triggered to shut down and the regulation potential is lower than a low voltage judgment criterion, it enters a standby working mode in which the secondary power supply is restarted for a transient working period to charge the voltage regulation and energy saving element. The power integration panel is electrically connected to the primary power supply and the secondary power supply, and inspects output status of the primary power supply and the secondary power supply in regular conditions to determine to boot up or shut down the secondary power supply.
Abstract:
A wireless communication keyboard includes a key module and a wireless communication module. The key module has a plurality of keys each can be depressed by a user to output a keyboard command. The key module also has a press combination including at least two keys which are depressed by the user at the same time to output a target search command. The wireless communication module is connected to the key module to receive the keyboard command and target search command, and has a linkage target setting state to search a linkable information device within a linkage range upon receiving the target search command. Thus user can quickly search the linkable information device through the press combination.
Abstract:
A thin keyboard structure includes a circuit board and a keycap assembly board located on the circuit board. The circuit board has a plurality of command portions to receive contact and generate command signals. The keycap assembly board has a frame with a plurality of press zones corresponding to the command portions. Each press zone has at least one press portion corresponding to one command portion and depressible to move towards the command portion. Each press zone also has a deformation portion centered on the press portion and coiled and extended continuously from the press portion towards the frame at a preset interval to provide deformation and return force for the press portion during movement towards the command portion. The press portion and deformation portion replace the driven mechanism used in the conventional keyboard, hence total thickness of the keyboard can be reduced to make the keyboard thinner.

Abstract:
A power supply for prolonging a hold-up time includes a main power supply system, and a hold-up power supply system connected in parallel to a power factor correction unit in the main power supply system. The hold-up power supply system includes an isolation transformer element connected to the power factor correction unit for receiving and transforming a first power to a third power, a power storage element for receiving the third power and storing as a hold-up power, and a power comparison unit connected between the power factor correction unit and the power storage element. The power comparison unit compares a second power generated from phase modulation performed by the power factor correction unit and the hold-up power, and outputs the hold-up power when the second power is smaller than the hold-up power, so as to sustain the power modulation unit to continue operating for a hold-up time.
