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.

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.

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.

Devices, methods, and systems for detecting proximity. A first light emitter emits light for a first time period while a light detector is not sensing. A second light emitter emits light for a second time period while the light detector is sensing. In some implementations, the first light emitter directly illuminates the light detector during the first time period, whereas the second light emitter is obstructed from directly illuminating the light detector during the second time period. In some implementations, the first light emitter is obstructed from illuminating a display during the first time period, and the second light emitter is obstructed from directly illuminating the light detector during the second time period. In some implementations, the first light emitter emits the light during the first time period such that the light detector maintains a linear responsivity during the second time period.

An example of a beverage dispenser includes a nozzle and a valve coupled upstream of the nozzle. A sensor is operable to detect an object within a detection zone and provide a signal representative of a distance between the object and the sensor. A controller is configured to receive the signal from the sensor. The controller is configured to determine a sub-zone from a plurality of sub-zones within the detection zone in which the object is located. The valve is controlled between an open condition to dispense the substance through the nozzle and a closed condition based upon the determined sub-zone.
