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 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:
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.
Abstract:
A method of multi-target switch transmission through an externally connected Bluetooth selection device aims to switch at least one input module having a wired connection mode to connect with a first information device and a wireless connection mode to connect with one of at least two second information devices. The method of switch transmission includes the steps of: establishing device connection, setting multi-target devices, determining wired connection mode or wireless connection mode, and determining the second information devices to be connected under the wireless connection mode. Through the externally connected Bluetooth selection device the input module can be switched and usable on the first information device and second information devices at the same time, and also establish connection with the corresponding information device according to requirements.
