A touch pad device includes a base unit, a touch unit and a resilient unit. The base unit includes a bottom plate and a supporting member disposed on the bottom plate. The touch unit includes a touch pad, a circuit board connected to the touch pad, and a switch button disposed the circuit board. The switch button corresponds in position to the supporting member. The resilient unit is disposed between the bottom plate and the circuit board, and includes a resilient plate connected to the bottom plate, and a reinforcing frame connected between the resilient plate and the circuit board. The resilient plate has two resilient piece portions, and an abutment portion connected to the resilient piece portions and supported by the supporting member. The abutment portion is positioned between the switch button and the supporting member. The reinforcing frame is connected to the resilient piece portions.

A full-area touch device includes a linkage unit disposed between a base unit and a touch control unit to drive a trigger switch of the touch control unit to be triggered by the base unit. The linkage unit is symmetrical relative to the trigger switch and includes an outer frame, an inner frame, linkage members fixed between the outer and inner frames, and a left plate and a right plate fixed to the base unit in the inner frame. A left front linkage member and a left rear linkage member are fixed between the left plate and the inner frame. A right front linkage member and a right rear linkage member are fixed between the right plate and the inner frame. A portion of an outer frame space not occupied by the base unit, the inner frame, the left plate and the right plate is defined as a floating chamber.

A low-travel key device includes a plate body, first and second stop sets, and a frame unit located between the first and second stop sets and including first and second frame members. The first frame member includes two first support arms each having a first end portion, and a first bight portion. The second frame member includes two second support arms each having a second end portion pivotally connected to the first end portion of a respective first support arm, and a second bight portion. A keycap is connected to the first and second bight portions, and is movable relative to the plate body between a non-depressed position, in which the first and second bight portions are away from the plate body, and a depressed position, in which the first and second bight portions are adjacent to the plate body.

A non-contact detection and recognition system is adapted to detect a gesture of an object, and includes a base, an optical detector and an optical notifier. The optical detector is disposed on the base, has a detection region, and is configured to detect the gesture of the object that appears in the detection region. The optical notifier is disposed in the base, and is configured to project notification light towards a place that corresponds in position to the detection region.

A stylus pen including a pen unit, a switch, and a control unit is provided. The pen unit includes a tip, and a shaft connected to the tip. The control unit is switchable between a default mode and an alternative mode in response to operation on the switch. In the default mode, the control unit emits a default-mode wave of a default-mode frequency to the shaft. In the alternative mode, the control unit emits an alternative-mode wave to the shaft in a pulsating pattern. The pulsating pattern has a wave period that includes a working period where the control unit emits the alternative-mode wave of the default-mode frequency, and a non-working period where the control unit stops emitting the alternative-mode wave.

A balanced low travel key switch device includes limiting recesses, first sliding recesses, and second sliding recesses mounted on a plate body. A first frame member has a first main body connected to a key cap, first lateral portions connected to the first main body, first pivotal portions connected to the first lateral portions, engaging blocks movable in the first sliding recesses, and positioning rods movable in the limiting recesses. A second frame member has a second main body pivotally connected to the key cap, second lateral portions connected to the second main body, second pivotal portions connected to the second lateral portions and the first pivotal portions, second engaging blocks disposed on the second lateral portions and movable in the second sliding recesses.

A touchpad device is to be operated by using a stylus pen, and includes a touchpad and a controller that are connected to each other. The controller is connected to an electronic device that includes a display panel, and operates in a stylus-pen mode where a handwriting area is presented on the display panel. When it is determined that a distance between the stylus pen and the touchpad is less than a preset pen-hover distance but is non-zero, the controller operates in a hover-move sub-mode where the controller outputs a control signal to enable the electronic device to present, in the handwriting area, the cursor moving, without presenting a trace of the cursor.

A light emitting module includes a light-guiding plate disposed under a light-shielding plate that includes a light-shielding portion and a hollow unit. The light-guiding plate has a light-exiting surface, a bottom surface, and a light-entering surface unit. The light-exiting surface has a base portion and a light-mixing portion. The light-mixing portion is formed on the base portion, is disposed within the hollow unit, and has refracting segments. Each of the refracting segments extends and tapers upwardly from the base portion. A reflection plate is disposed under the bottom surface. A plurality of light emitting members are disposed below the light-shielding portion. The light-entering surface unit faces the light emitting members.
