Abstract: An illuminated keyswitch includes a base, a keycap, a lift mechanism, and a light source. The keycap includes a cap body and a light guiding rod. The lift mechanism is connected to between the light guiding rod and the base, such that the keycap can vertically move relative to the base through the lift mechanism. The light source is disposed between the light guiding rod and the base and emits light toward the light guiding rod. The light enters the light guiding rod through an end portion of the light guiding rod and then emits out the light guiding rod from another end portion of the light guiding rod and a side surface adjacent to the another end portion toward the cap body. Thereby, the whole cap body can receives relatively uniform back light.

Abstract: A light emission module and a light guide plate and a manufacturing method thereof are provided. The light guide plate is configured to guide the light received and has a first lateral surface and a tongue extending from the first lateral surface toward a light source. The tongue has a flat end surface that faces or engages with the light source. The light guide plate receives the light emitted from the light source by the flat end surface, so as to reduce or eliminate the gap between the light source and the light guide plate. Therefore, the loss of light energy during the light traveling in air is effectively reduced, and the intensity of light received by the light guide plate from the light source meets expectation, improving the lighting effect of the light emission module.

Abstract: A keyboard wirelessly connecting to one of multiple hosts is provided. Each host has a device ID code and a device authorization code. The keyboard includes a host selection device, a storage device, a connection device, and a communication device. The storage device stores a lookup table including multiple host codes, each corresponding to one device ID code and one device authorization code. The host selection device selects a candidate host code when receiving a first operation. The connection device receives a second operation different from the first operation. When the second operation lasts shorter than a threshold period, the keyboard connects to a host having the device ID code and the device authorization code corresponding to the candidate host code. When the second operation lasts longer than the threshold period, the keyboard updates the device ID code and the device authorization code corresponding to the candidate host code.

Abstract: A current source inverter includes a controller, an input unit, a buffer unit, a modulating unit, and a commutator. The controller generates a switch control signal, an inverse switch control signal, a first pulse width modulation control signal, and a second pulse width modulation control signal. The input unit stores and transmits input power of a direct current power supply according to the first pulse width modulation control signal. The buffer unit is coupled to the input unit for receiving and transmitting the input power. The modulating unit generates and outputs a full-wave rectified sinusoidal current according to the second pulse width modulation control signal and the input power. The commutator converts the full-wave rectified sinusoidal current into an alternating current according to the switch control signal and the inverse switch control signal and outputs the alternating current to a load or a utility line.

Abstract: A keyswitch structure includes a base, a keycap, at least one lift mechanism, a link, and a restoration mechanism. The lift mechanism is connected to and between the base and the keycap. The link is moveably on the base. The restoration mechanism is disposed on the link and the base and can generate a restoration force. When the keycap is pressed down by a user to move toward the base, a sliding portion of the lift mechanism slides on the base to drive the link to move relative to the base. Further, when the pressing on the keycap by the user is eliminated, the restoration force urges the link to move to drive the sliding portion to slide reversely, so that the keycap moves away from the base.
