A photoelectric switch key is provided, which includes a shell, a circuit board, a photosensitive component and a press component. The photosensitive component is electrically connected to the circuit board, and the press component is provided with a light-shielding member. The press component is movably mounted on the shell to enable the light-shielding member to move relative to a light-receiving surface of the photosensitive component. The photosensitive component is capable of receiving external light when the light-shielding member is moved away from the light-receiving surface of the photosensitive component. The light-shielding member is adjacent to and shielding the light-receiving surface of the photosensitive component when the press component is pressed. The light-shielding member is enabled to completely block the external light from irradiating on the photosensitive component when the key is pressed by the user, which achieves the function of the key, and improves the sensitivity of the key.

An optical proximity sensor system to detect a distance to a target object is provided. The optical proximity sensor system includes a laser that generates an emitted optical beam at a linear polarization and an optical cavity system that includes an optical cavity defined by a distance between the laser and the target object. The target object reflects the emitted optical beam to generate a reflected optical beam. A partially reflective mirror diverts a portion of the emitted optical beam and/or the reflected optical beam. A photodetector receives the diverted optical beam and generates a proximity signal that has a frequency that is indicative of the distance to the target object based on the diverted portion of the at least one of the emitted optical beam and the reflected optical beam. A proximity processor calculates the distance to the target object based on the frequency of the proximity signal.

A switch assembly according to an example of this disclosure includes a disk rotatable about a disk axis in a first circumferential direction and a second circumferential direction opposite the first circumferential direction. A U-shaped spring is fixed to the disk. Rotation of the disk in the first circumferential direction moves the disk in a first axial direction, and rotation of the disk in the second circumferential direction moves the disk in the first axial direction.

An optical keyswitch includes a keycap, a support mechanism, and a switch module. The support mechanism is disposed below the keycap and configured to support the keycap moving upward and downward, the support mechanism comprising a first frame and a second frame, the first frame having a sliding end. The switch module includes a circuit board, an emitter, and a receiver, the emitter and the receiver are electrically connected to the circuit board, and the emitter emitting an optical signal to the receiver. When the keycap is pressed, the first frame is driven by the keycap to slide substantially parallel to the circuit board and block the optical signal with the sliding end, so the switch module is triggered to generate a triggering signal.

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.
