An optical detection device includes a substrate, a housing, an optical modulating component, an optical sensor and a cover. The housing is disposed on the substrate and includes a first aperture. The housing is unvaried due to inspection standard or design requirement of the optical detection device. The optical modulating component is disposed on the housing and aligning with the first aperture. The optical sensor is disposed on the substrate and adapted to receive an optical signal passing through the optical modulating component and the first aperture. The cover is disposed on the housing to cover the first aperture. The cover is replaceable for attaching the cover varied for the inspection standard or the design requirement to the unvaried housing in response to a surface of the cover opposite to the housing matched and engaged with a light penetrating area on the optical navigation apparatus.

A sensor switch with water suppression includes a sensor electrode and a photodiode connected to an evaluation circuit. The evaluation circuit generates a capacitive sensor signal indicative of an electrically-conductive object in the proximity of the sensor switch and an optical sensor signal indicative of an object at least partially opaque or impermeable to light in the proximity of the sensor switch. The capacitive sensor signal and the optical sensor signal are correlated with one another to generate an output signal.

A sensor switch including a capacitive sensor and/or an optical sensor configured to detect the presence of a body part and a housing defining a mounting plane. The housing further contains at least one lighting window providing a cover for at least one light source that is disposed in the housing. Such light source(s) provide(s) corresponding light beam(s) in a plane parallel to the mounting plane or at an angle with respect to the mounting plane.

Provided is an apparatus for generating a vibrotactile sensation. The apparatus for generating a vibrotactile sensation includes a light source generating light, a vibration layer generating a vibration by receiving the light, a vibration detection unit disposed adjacent to the vibration layer to detect a vibration signal of the vibration layer, and a control unit connected to the vibration detection unit to determine the vibration of the vibration layer by using the vibration signal. Here, the vibration layer includes a thermo-elastic layer that has a first thermal expansion coefficient and a photo-thermal conversion layer that is disposed on the thermo-elastic layer and has a second thermal expansion coefficient less than the first thermal expansion coefficient.

This application is directed to touchless interfaces. Some embodiments disclosed are directed to plug and play replacements for casino gaming machine touch-based interfaces on, e.g., slot machines. Existing slot machine interfaces can be replaced with touchless interfaces of the inventive subject matter to enable touchless interaction with gaming machines. This allows people in casinos to minimize contact with gaming machines to stymy the spread of diseases like COVID-19.

A user may provide finger press input to a surface such as a touch sensitive input surface. The input surface may be formed from a two-dimensional touch sensor overlapping a display of an electronic device. The electronic device and an associated device such as a finger-mounted device may form a system for gathering the finger press input from the user. A sensor may be used in monitoring when the finger-mounted device and a user's finger in the device approach the input surface of the electronic device. In response to detection of the finger near the input surface, actuators in the finger-mounted device may squeeze the finger inwardly to cause a finger pad on the finger to protrude outwardly towards the input surface, thereby softening impact between the finger and the input surface. The electronic device may also have an array of components to repel the finger-mounted device.

The disclosure describes various aspects of different techniques for flexible touch sensors and method for wide-field imaging of an atom or ion trap. A touch sensor is described for controlling movement of a control element for use with the trap that includes an outer structure and an inner structure that holds the control element and moves within the outer structure. The trap is inside an ultra-high vacuum (UHV) environment and the outer and inner structures are outside the UHV environment and separated by a UHV window. The control element or elements are brought into proximity of the UHV window in connection with controlling targets at the trap. The inner structure can stop moving within the outer structure to avoid damaging of the UHV window with the control element(s) in response to the inner structure being in physical contact with or within a set proximity of the outer structure.

A light device control apparatus is designed to pair with a traditional switch device that has a traditional switch for accepting a first user manual operation to control a target device connected to the traditional switch device with an electrical wire. The traditional switch device has a connecting structure. The light device control apparatus has an attaching device, a cover body, a replacement switch and a wireless controller. The attaching device is attached to the connecting structure of the traditional switch device. The wireless controller wirelessly controls the target device. The replacement switch and the wireless component are not overlapped to each other vertically with respect to the surface cover of the traditional switch device.

An audio/video (A/V) recording and communication doorbell device includes an input port, a switch, a first power supply, a second power supply, a button, a first controller, and a second controller. The switch is electrically coupled across the input port. The first power supply receives power from the input port and powers a first power supply rail, and the second power supply powers a second power supply rail. The button, when pressed, activates a signaling device. The first controller is at least partially powered from the first power supply rail and closes the switch in response to the button being pressed. The second controller is at least partially powered from the second power supply rail.
