Embodiments of the present disclosure disclose a method for improving a performance of a pulsed-ultraviolet (PUV) device. The method includes monitoring an input current across a circuit breaker in communication with a UV lamp, where the input current is delivered by a power signal and is interrupted by the circuit breaker upon exceeding a predefined cut-off current; generating a pulse signal having a set of frequencies based on the power signal for driving the UV lamp, where the pulse signal is associated with a predetermined cut-off frequency that increases the input current beyond the cut-off current; determining a predefined threshold current less than the cut-off current; and configuring the pulse signal with multiple distinct pulse frequencies per second for a predefined configuration period based on the input current exceeding the threshold current. The distinct pulse frequencies per second include at least one pulse frequency greater than the cut-off frequency.

The invention provides an input device including a holder, a first wheel, a slider, and a first pressure part. The first wheel is disposed on the holder, and includes a side surface, a circle center, and a segment adjusting structure. The segment adjusting structure is disposed on the side surface in a manner of surrounding the circle center. The slider is disposed on the holder, and is movable relative to the holder to move toward or away from the circle center. The first pressure part includes two first ends. One of the first ends is connected to the slider, and as the slider moves toward or away from the circle center, interference between the other first end and the segment adjusting structure is increased or reduced.

A switch apparatus for an automobile with a reduced size by installing a touch type switch apparatus inside a dial switch apparatus is provided. A switch apparatus for an automobile according to the present disclosure includes a main body which has an open lower side, a cover body which is inserted into the open lower side of the main body and is coupled to the main body, a dial switch apparatus which is installed on the main body and has an annular wheel knob rotatable with a virtual rotation axis disposed in a vertical direction as a rotation center, a touch type switch apparatus which is installed on the main body and has a capacitive touch pad which is touched by a user and pressed in an up-down direction, a main PCB which is coupled to the cover body to be disposed in the main body and into which a switch signal is input from the dial switch apparatus and the touch type switch apparatus, and a case body which is coupled to the main body and has a hole, through which the wheel knob and the capacitive touch pad are exposed, on an upper side, in which the capacitive touch pad is disposed inside the wheel knob.

Embodiments are directed to a sensing membrane that is coupled with electrical terminals of a key switch and a light source. This may allow the membrane to be both configured to transmit a signal in response to actuation of keyboard key cap and illuminate an illuminable symbol of key cap. In one aspect, the membrane includes a set of deformable layers separated by a spacer layer. Terminals of the key switch are connected to distinct ones of the set of deformable layers and positioned within a cavity defined by the spacer layer. A light assembly may be positioned along and configured to move with one of the set of deformable layers. Depression of a key cap toward the set of deformable layers causes the set of terminals to move and initiate a switch event.

A modular electrical wiring device assembly including, but not limited to, a frame assembly having a top surface, a bottom surface, a width, a length and a height; a primary opening defined by a primary opening surface, wherein the primary opening is positioned through the top surface and the bottom surface; a cover plate positioned over and in contacting relation to the top surface of the frame assembly, wherein the cover plate includes a cover plate opening positioned over and in line with the primary opening; and a modular electrical wiring device positioned through the cover plate opening and the primary opening, wherein a portion of the modular electrical wiring device is positioned below the bottom surface of the frame assembly.

A device may include a display portion that includes a display housing and a display at least partially within the display housing. The device may also include a base portion pivotally coupled to the display portion and including a bottom case, a top case coupled to the bottom case and defining an array of raised key regions, and a sensing system below the top case and configured to detect an input applied to a raised key region of the array of raised key regions.

The first wheel is disposed on the holder, and includes a side surface, a circle center, and a segment adjusting structure. The segment adjusting structure is disposed on the side surface in a manner of surrounding the circle center.

One of the first ends is connected to the slider, and as the slider moves toward or away from the circle center, interference between the other first end and the segment adjusting structure is increased or reduced.

An illuminated keyswitch structure includes a base plate, a drive circuit board under the base plate, a spacer between the drive circuit board and the base plate, and a light-emitting part on the circuit board. The spacer has a through hole communicating with an opening of the base plate in a vertical direction. The sidewall of the through hole is opaque. The light-emitting part is located in the through hole, and falls within a projection of the opening in the vertical direction. The light-emitting part has a top surface that is lower than or equal to a bottom surface of the base plate in the vertical direction. The structure of the illuminated keyswitch structure around the light-emitting part can keep flat by the spacer. The spacer can prevent the light-emitting part from structurally entering the opening, avoiding structural interference between the light-emitting part and other components above the base plate.

The present invention discloses a method to manufacture a keycap for keys of a keyboard, including: providing a top fabric layer and a molding film disposed beneath the top fabric layer; molding the molding film and the top fabric layer to form a film structure having an inner surface; and providing a keycap body having an upper surface, wherein the outline of the upper surface matches with that of the inner surface to form the keycap. In the present invention, the keycap is formed using the film structure and the keycap body by plastic injection or adhesion agent, the keycap is further manufactured as keys, and a symbol is engraved on the upper surface of the film structure by laser. Because the backlit device's light transmits through the keycap, users can recognize the symbols on the keys.
