Abstract:
A start-up architecture of a redundant power supply system is provided. The redundant power supply system is electrically connected to a load, and includes N+M power supplies, where N≧1 and M≧1. The start-up architecture includes a power integration backboard electrically connected to the power supplies, and a mode switching member. The power integration backboard includes an activation circuit, and has a synchronous booting mode in which the power supplies are simultaneously activated and a sequential booting mode in which the power supplies are sequentially activated. The mode switching member is electrically connected to the activation circuit, and receives a manual switching of a user to output a synchronous booting signal that controls the power integration backboard to enter the synchronous booting mode and to output a sequential booting signal that controls the power integration backboard to enter the sequential booting mode.
Abstract:
A redundant power supply system providing alternate standby includes at least one primary power supply, at least one secondary power supply and a power integration panel. Each primary power supply receives a first power ON/OFF signal and starts to output a primary duty power. Each secondary power supply receives a second power ON/OFF signal and starts to output a secondary duty power. The power integration panel is electrically connected to the primary power supply and the secondary power supply and has a standby mode to receive a power ON/OFF signal from a motherboard and output alternately at a selected time interval the first power ON/OFF signal to the primary power supply or the second power ON/OFF signal to the secondary power supply to make the primary power supply and the secondary power supply on standby alternately.
Abstract:
A thin keyboard command trigger structure includes a circuit board and a frame. The frame is stacked over the circuit board and formed an outer frame, a plurality of inner frames and a plurality of keycaps in an integrated manner. The outer frame has a plurality of holding zones. Each keycap is held in one of the holding zones. The outer frame and the keycap are bridged by one inner frame. Each inner frame has at least two first connecting portions connected to the outer frame and at least two second connecting portions connected to the keycap. Each first connecting portion and each second connecting portion are bridged by a support portion which has a bend spot and can generate deformation when the keycap is moved to the trigger portion. The support portion at the second connecting portion is at an elevation higher than the first connecting portion.

Abstract:
A support rack for a wireless electronic device is installed on a keyboard and integrally fabricated from a plastic sheet. The support rack includes a positioning segment, a bearing segment and a support segment. The positioning segment includes a holding zone to hold a wireless electronic device. The bearing segment is connected to one side of the positioning segment opposite to the keyboard and includes at least one retaining portion. The support segment includes a leaning section connected to the positioning segment via a first bend portion, and a holding section connected to the leaning section via a second bend portion to couple with the retaining portion. The first bend portion is formed at a thickness smaller than that of the leaning section and the positioning segment, and the second bend portion is formed at a thickness smaller than that of the leaning section and the bracket section.
Abstract:
A power supply device with reduced power consumption is electrically connected to a motherboard. The motherboard outputs a power-on signal or a power-off signal to the power supply device when being triggered. The power supply device includes a standby power supply module which modulates an external power to output a standby power. Upon receiving the power-on signal, the power supply device deactivates the standby power supply module, but activates a main power supply module to modulate the external power to output an operating power to the motherboard to replace the standby power. Upon receiving the power-off signal, the power supply device deactivates the main power supply module, but reactivates the standby power supply module so that the standby power supply module outputs the standby power to the motherboard.
Abstract:
A headphone wireless expansion device for switching among multiple targets is connected to an information device to receive audio data which is then transmitted to a headphone for playing. The headphone wireless expansion device includes multi-target connection data and an audio control mechanism. The multi-target connection data includes a plurality of device identification codes, a plurality of device authorization codes corresponding to a plurality of information devices respectively, and a plurality of audio tags corresponding to the device identification codes and the device authorization codes respectively. The audio control mechanism searches the audio tag having audio features same as that of the unrecognized audio signal, and reads the corresponding device identification code and device authorization code. The headphone wireless expansion device enables a conventional wired headphone to wirelessly connect with the information device and switch among multiple information devices via a voice control method through identifying the audio tag.
Abstract:
A display method for distinguishing multiple linking target aims to switch data transmission link between an input device and at least two information processing systems through a plurality of transmission channels in a wireless transmission fashion. The input device includes a display module with a first display zone and a second display zone. The display method comprises steps of: detecting linkable information processing systems, setting transmission channels, determining a linking target and displaying information of linked transmission channel. Through the steps of detecting linkable information processing systems, setting transmission channels and determining a linking target, a data transmission link can be established with one of the information processing systems. Users can further display the device identification code through the step of displaying information of linked transmission channel to be informed of the information processing system currently linked to the input device.
Abstract:
An illuminated keycap for generating soft light is located in a keyboard which includes a command circuit board located beneath the keycap and a lighting unit to project light to the keycap. The keycap includes a press surface, a connecting section extended from the press surface towards the command circuit board and a color display surface extended from the connecting section and parallel to the press surface. The press surface, connecting section and color display surface form a light retaining zone. The press surface has a top surface coated with a first pigment layer. The color display surface has a bottom surface coated with a second pigment layer whose color is different from the first pigment layer. The first and second pigment layers form a mixed color so that light generated by the lighting unit to enter the light retaining zone is emitted softly through the connecting section.
Abstract:
A locally illuminated keycap is located in a keyboard. The keyboard includes a lighting unit to project light to the keycap. The keycap includes at least one top edge to form an opaque press surface, at least one bottom edge located below the press surface to form a light incident surface to receive light, and at least one transparent light emitting surface connecting to the top edge and bottom edge to emit light. The press surface and light emitting surface form an inclined angle between them greater than 90 degrees. The press surface, light incident surface and light emitting surface jointly form a light retaining zone. Light generated by the lighting unit projects to the light incident surface and enters the light retaining zone, and is masked by the opaque press surface to emit locally through the transparent light emitting surface.
