The invention proposes a key module for a key of a keyboard. The key module includes a module base, a module cover that can be coupled with the module base and a key tappet for coupling a keycap that is translucent in at least one symbol section. The module base includes at least one through-hole between a bottom section of the key module and the module cover. The module cover includes a section that is translucent for the light from a light source. The light source is a color-changeable light source for backlighting the symbol section of the keycap. The translucent section of the module cover is aligned with the at least one through-hole when the module cover is coupled to the module base.

A portable keyboard includes: a polygonal pillar-shaped main body having a battery embedded therein; a key assembly connected to the main body, the key assembly having a plurality of key arrangements; and a connecting member formed to extend down to the bottom of the key assembly while connecting the key assembly and the main body to each other, wherein at least one key arrangement in the key assembly allows information to be entered by a touch, a first element is provided to the main body, a second element is provided to the key assembly, and the first element and the second element are attached to each other by magnetic force such that the key assembly is wound.

Keyboards and other input devices are provided with membranes that extend under the keycaps or buttons. The membranes are flexible and can support conductive structures, traces, and electrical switch connections to enable effective key switches, lighting, and fluid-tightness for the keyboard. The flexible membrane is positioned near the keycaps to prevent ingress of fluids and debris into the lower portions of the key assemblies. In some cases, the flexible membrane also provides support for an interstitial layer that extends between keycaps.

A keycap structure includes a keycap body and a display module. The keycap body includes a top wall and a lateral wall. The lateral wall is extended downwardly from a periphery region of the top wall. An accommodation space is defined by the top wall and the lateral wall collaboratively. The display module is disposed within the accommodation space. The display module includes a light-transmissible circuit substrate and plural light-emitting elements. The plural light-emitting elements are installed on the light-transmissible circuit substrate and electrically connected with the light-transmissible circuit substrate. After the light beams are transmitted through the light-transmissible circuit substrate and the top wall sequentially, the light beams are outputted from the keycap body. The light beams from the plural light-emitting elements are collaboratively formed as a luminous zone. Moreover, a pattern corresponding to the luminous zone is shown on the display module.

The present invention provides a touch device, including a cover plate, a circuit board, a bracket, and a noise reduction layer group. The circuit board is fixed below the cover plate. The circuit board is provided with a trigger zone located on a bottom surface, and includes an elastic sheet located in the trigger zone. The bracket is disposed below the circuit board. The noise reduction layer group is disposed between the bracket and the elastic sheet.

A backlight module includes a circuit board, a light-emitting unit, a light-reflecting plate, a light guide plate, and a light-shielding sheet. The light-emitting unit is disposed on the circuit board. The light-reflecting plate is disposed above the circuit board. The light guide plate is disposed above the light-reflecting plate and includes a single-key light guide area. The single-key light guide area includes an accommodating hole and a light-blocking structure. The accommodating hole runs through the single-key light guide area and accommodates the light-emitting unit. The light-blocking structure and the light-emitting unit are arranged in a direction. The light-shielding sheet is disposed above the light guide plate.

A latch system for an electrical equipment enclosure includes a latch arm receiver adapted to be connected to an associated enclosure door. A latch arm assembly is adapted to be connected in operative engagement with an associated circuit breaker. The latch arm assembly includes a chassis and a latch arm that moves relative to the chassis between: (i) a first arm position; (ii) a second arm position; and (iii) an intermediate arm position between the first arm position and the second arm position. A latch arm spring biases the latch arm toward its first arm position. A handle is rotatably connected to the chassis and operatively connected to the toggle of the circuit breaker. The handle is movable to and between an ON handle position, a TRIP handle position, an OFF handle position, and a RESET handle position. The handle is operatively connected to the latch arm such that the latch arm is positioned in the second arm position when the handle is located in said RESET handle position. The latch arm spring biases the latch arm into one of the first position and the intermediate position when the handle is in any one of said ON handle position, said TRIP handle position, and said OFF handle position. A lockout plunger is connected to the handle to rotate with the handle and is movable between a disengaged position and an engaged position, wherein the lockout plunger prevents movement of the handle from the OFF handle position to the ON handle position when the lockout plunger is in its engaged position

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.

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.

Systems and methods for enabling a Graphical User Interface (GUI) manipulation using hand gestures over a hovering keyboard are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: detect a hand gesture using proximity sensors disposed on a hovering keyboard coupled to the IHS, and manipulate a task map rendered on a display coupled to the IHS in response to the detection.
