A sensor assembly including a sensor, a sensor housing that carries the sensor, a mounting member that pivotally engages with the sensor housing, an adjustment member for selecting an angular position of the sensor housing relative to the mounting member, and a locking mechanism for locking the sensor housing at the selected angular position relative to the mounting member. The adjustment member is moveable relative to the mounting member between a first location and a second location, and engages with the sensor housing to pivot the sensor housing about a pivot axis relative to the mounting member between a first angular position and a second angular position.

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 light switch network comprises a plurality of light switch units, each comprising a gesture interface to sense a user gesture by receiving at least one gesture signal from a sensing zone, and configured to exchange one or more gesture status signals with at least one other switch unit in the network in relation to the received gesture signal; each switch being enabled, on receiving the gesture signal: in a first mode, to change a designated switch mode and/or state in response to the gesture signal; or in a second mode, to not change the designated switch mode and/or state according to one or more conditions associated with the status signals received from the other switch unit.

An actuation device for a public transport vehicle to avoid transmission of bacteria during the actuation. The device can be actuated by a predefined contactless actuation gesture, the device having a sensor unit that measures without contact and an evaluation unit, which is connected to the sensor unit. The sensor unit can generate a sensor signal transmit the sensor signal to the evaluation unit when an object, in particular a finger or a hand of a person, performs, within a detection space of the sensor unit, a movement at a distance from the actuation device, the signal being dependent on the movement sequence of the movement. The evaluation unit can check whether the movement is a predefined contactless actuation gesture, by which the actuation device can be actuated. If the movement is such an actuation gesture, a control signal is generated for a device of the vehicle.

The present invention provides a proximity sensing device, which comprises an ambient light calibration digital-to-analog converter and at least one crosstalk calibration digital-to-analog converters. The proximity sensing device is able to quickly generate calibration parameters for the interference caused by the ambient list and crosstalk caused by different reflection, to calibrate the sensed signals to avoid wrong judgments.

A color temperature switching scheme for an LED lighting device is disclosed. The color temperature switching scheme comprises a plurality of different color temperature performances correspondingly generated by a plurality of different paired combinations of a first electric power allocated to a first LED load emitting a light with a first color temperature and a second electric power allocated to a second LED load emitting a light with a second color temperature such that a mingled color temperature between the first color temperature and the second color temperature can be generated thru a light diffuser. For tuning the mingled color temperature of the LED lighting device a reverse yet complementary power adjustment process for distributing a total electric power T between the first LED circuit and the second LED circuit is required such that a total light intensity remains unchanged while the mingled color temperature is being adjusted.

A system for interacting with a screen without touching it, comprising a source of radiating energy directed into a predefined area, at least one directionally sensitive sensor that detects the radiation when it's reflected off of an object within the predefined area, and a processor that calculates position and motion information of the object and generates therefrom image information, which it sends to a screen where it is displayed.

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.

A control circuit for an input device including a micro-switch is provided. The control circuit includes an input circuit, a receiver circuit, a control unit, and a detecting unit. The input circuit includes a first contact and a second contact for electrically connecting to the micro-switch. The receiver circuit includes a third contact and a fourth contact for electrically connecting to the micro-switch. The control unit is electrically connected to the first contact and the third contact for providing an input signal via the first contact to the micro-switch and receiving a switching signal from the micro-switch via the third contact. The detecting unit detects a voltage of the second contact to generate a detecting signal. The control unit receives the detecting signal to determine a type of the micro-switch.

A configuration is implemented that can adjust a stroke of an operation section of a switch required to cause predetermined processing to be executed. The present disclosure includes an operation section that can move in a predetermined direction from an initial position by a user operation, a position adjustment section that adjusts, in the predetermined direction, an amount of movement of the operation section from the initial position to a detection position, a position detection section that detects a position of the operation section with respect to the detection position, and a control section that controls execution of processing corresponding to the detection position based on a detection result from the position detection section.
