Abstract:
A redundant power supply system for reducing standby power consumption includes a plurality of power supply modules and a power integration backboard. Each of the power supply modules includes an operating power modulation unit, a standby power modulation unit and a control unit connected to the standby power modulation unit. The power integration backboard is connected to the power supply modules, and includes an integration output unit and a standby power consumption management unit. The integration output unit integrates the operating powers and the standby powers of the power supply modules to provide an output to a load. The standby power consumption management unit outputs an operating signal to the control unit of each of the power supply modules according to a power consumption condition of the load, such that the control unit can activate or deactivate the standby power modulation unit according to the operating signal.
Abstract:
A method for controlling light emission of a light sensing keyboard is to save in advance a driving correlation table including a plurality of driving codes in the light sensing keyboard. Each driving code corresponds to a trigger signal and is triggered by the trigger signal to generate a driving signal which defines a light emission mode. When a light detection unit detects ambient light parameters, the trigger signal is generated and the driving code corresponding to the trigger signal is read from the driving correlation table. A control unit generates the driving signal according to the driving code to drive light emission elements to emit light and also control each light emission element to execute the light emission mode corresponding to the driving signal, thereby synchronous or asynchronous colored light alteration can be generated to provide flickering or alternate light alteration effect.

A keyboard equipped with light emitting structure comprises a plurality of keycap portions and a light guide command circuit board which includes an upper light guide plate, a lower light guide plate and a middle plate located between the upper and lower light guide plates. The upper and lower light guide plates have respectively an upper trigger portion and a lower trigger portion at one side facing the middle plate. The middle plate has a hollow zone corresponding to the upper and lower trigger portions, a plurality of coupling portions corresponding to the keycap portion and a plurality of apertures. The upper light guide plate also has an upper mask layer at one side facing the keycap portion and having a transparent zone. The command circuit board receives light from a light emitting unit and transmits the light to illuminate the keycap portion through the transparent zone.

A keycap module fabricated by integrated injection includes a support frame which has a plurality of interlaced rims to define a plurality of keycap installation apertures. Each keycap installation aperture holds a keycap which has four sides and four corners. Each side of the keycap and each rim of the support frame have respectively a first wall and a second wall bridged by a movable arm. The keycaps, movable arms and support frame are integrally formed by injection. Each movable arm has a fist connecting section connected to one corner of the keycap and a second connecting section connected to the first connecting section at a first bend spot. The second connecting section is extended towards a neighboring corner of the keycap and connected to one rim of the support frame.

A power supply capable of increasing the lifespan of battery modules controls the duty state of a main power supply system through a state switch control module. The state switch control module includes a power supply switch unit and a state switch unit. The power supply switch unit has a first power supply state in which the state switch unit outputs a first signal to allow the main power supply system to output a first power to charge a battery module, and a second power supply state in which the state switch unit outputs a second signal to allow the main power supply system to stop outputting the first power, and the battery module outputs the second power when the first electric potential of the first power is lower than the second electric potential of the second power.

Through the connection arm bridged the first and second keycaps to substitute the conventional driven mechanism total thickness of the keyboard can be reduced, and assembly also is simpler.
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.
