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.

Electrical equipment such as a tablet computer cover, a laptop computer, or other equipment may include keys. Each key may have a key member. Coatings such as opaque coating layers may be formed on the key members. Opaque coating layers may be patterned to form symbol-shaped openings associated with key labels. Opaque coating layers may also have recessed peripheral portions and other features to enhance the appearance of the keys. Metal coating layers such as physical vapor deposition metal layers may be incorporated into the keys. Key members may have outer surfaces and opposing inner surface on which patterned coating layers may be formed. Peripheral edge portions of the key members may extend between the outer and inner surfaces and may be coated with metal coating layers to form reflective metal trim structures. Backlight illumination for the keys may be formed form light sources such as light-emitting diodes.

The invention provides an input device, including: a substrate, including at least one connecting portion and at least one limiting portion; at least one key, including at least one first engagement portion and at least one second engagement portion located on two opposite sides, where the first engagement portion is in contact with the connecting portion, so that the key can rotate relative to the substrate by taking the connecting portion as a rotation center, and the second engagement portion faces the limiting portion and is spaced apart from the limiting portion; and a buffer unit, disposed on at least one of two surfaces of the limiting portion and the second engagement portion facing each other. By disposing the buffer unit, noise generated due to the collision between the second engagement portion and the limiting portion can be decreased.

The present invention provides a touch control device, including a cover plate, a circuit board, an elastic sheet body and a bracket. The circuit board is fixedly arranged below the cover plate. The circuit board is provided with a triggering region located on a bottom surface. The elastic sheet body is arranged under the circuit board and corresponds to the triggering region. The bracket is disposed below the circuit board. The bracket is provided with a first side and a second side which are opposite and a middle region located on the second side and further comprises two cantilevers which are located at both sides of the middle region of the second side and extend towards opposite directions. The elastic sheet body is in contact with the middle region. The end of each cantilever is provided with an abutting-joint structure and is in contact with the circuit board by the abutting-joint structure.

A keyboard device and an operating method thereof are provided. The keyboard device includes a microcontroller, a drive circuit, a backlight module, and a plurality of key units. The microcontroller is coupled to a computer device. A detection module of the computer device detects an input mode of the computer device. The plurality of key units is disposed on the backlight module. The plurality of key units each has a plurality of character symbols corresponding to different input modes. The microcontroller outputs a control signal to the drive circuit according to the input mode. The drive circuit drives the backlight module according to the control signal to selectively illuminate one of the plurality of character symbols of each of at least a portion of the plurality of key units.

The disclosure provides a base plate adapted for disposing a support unit. The base plate includes a thermally sensitive material plate and a connecting member. The connecting member includes a junction part joined to the thermally sensitive material plate, and a connection part extending from the junction part. The connection part protrudes from a surface of the thermally sensitive material plate. A key assembly, an illuminated key input device, and a manufacturing method of the base plate are also provided.

A method and apparatus for ranging finding of signal transmitting devices is provided. The method of signal reception is digitally based only and does not require receivers that are analog measurement devices. Ranging can be achieved using a single pulse emitting device operating in range spaced relation with a minimum of a single signal transmitter and a single digital receiver and processing circuitry. In general a plurality of transmitting pulsed emitters may be ranged and positioned virtually simultaneously in 3-dimensions (XYZ coordinates) using a configuration of a plurality of digital receivers arranged in any fixed 3-dimensional configuration. Applications may involve at least one single transmitter to receiver design to determine range, or at least one transmitted reflecting signal off from an object to determine range.

The invention relates to a peripheral (1) including at least one transparent key (2), actuable under the effect of pressure and engaged in an opening (11) arranged on a first face (10a) of a case (10), the peripheral (1) including a system (13) for controlling and detecting a pressure exerted on the key (2), and at least one screen (4) allowing symbols (3) to be displayed through each key (2) via respectively a display path (5), the control and detection system (13) including a flexible membrane (14) ensuring an actuating force and a pressure feedback effect and including at least one orifice (17), each orifice delimiting a display path (5) for a key (2), and each orifice (17) being delimited by a border (17a) cooperating with a key (2).

A module cover comprising a through-hole for a passage of a key tappet of the key, a light injection region for injecting light from a light source into the module cover, a first light output region for outputting a first portion of the light, and a second light output region for outputting a second portion of the light out of the module cover. The first light output region and the second light output region, and a first light directing portion and a second light directing portion, are arranged on different sides of the through-hole. The first light directing portion directs a first portion of the light to the first light output region and a second portion of the light to the second light directing portion, and the second light directing portion directs at least part of the second portion of the light to the second light output region.
