Abstract:
This disclosure is generally directed to a multi-value selection switch that includes an engagement surface with an integrated touch sensor. The integrated touch sensor includes a plurality of detectable positions that correspond to, for instance, a range of absolute or relative target input values between a predefined minimum and maximum. The engagement surface further defines a switch that actuates/activates based on detecting a user-supplied force and/or based on a user momentarily holding a finger/pointer position. A user can select a target input value by bringing a finger or other pointer within operable proximity of an associated detectable position and actuating the switch and/or momentarily pausing. In response, the selection switch outputs a control signal to an associated device to cause the same to adjust operation.
Abstract:
A proximity sensor with integrated control features includes a sensing circuit that detects a target feature in proximity thereto and generates a sensor signal responsive to detection of the target feature, an interface circuit that receives inputs from an external device and conditions the inputs to provide digital logic outputs, output electronics that selectively provide actuation signals for driving a load operatively connected to the proximity sensor, and a microcontroller unit in communication with the sensing circuit, the interface circuit, and the output electronics. The microcontroller unit receives sensor signals and digital logic outputs from the sensing circuit and the interface circuit, samples the sensor signals and digital logic outputs, and selectively provides activation signals to the output electronics based on the state of the digital logic outputs and/or the sensor signals, wherein the activation signals cause the output electronics to output the actuation signals to drive the load.
Abstract:
An apparatus includes a display screen, and an optical proximity sensor module disposed behind the display screen. The optical proximity sensor module includes a light emitter operable to produce light having a wavelength for transmission through the display screen toward a target object, and a light sensor operable to sense light reflected by the target object and having the wavelength. The optical proximity sensor module can includes means for reducing a maximum energy density of a light beam produced by the light emitter. The means for reducing the maximum energy density of the light beam is disposed between the light emitter and the display screen so as to intersect the light beam produced by the light emitter. In some cases, there are multiple light emitters collectively operable to provide sufficient optical energy for proximity sensing without producing a visible spot on the display screen. These and other techniques can help reduce or eliminate display screen distortion caused by energy from the light emitters.

Abstract:
Drug delivery device with electronically controlled and axially displaceable piston drive member (10) adapted to engage a loaded cartridge piston. The piston drive member is moveable between a proximal loading position in which a cartridge can be received and a distal loaded position in engagement with the piston. A proximity sensor (11,12) provides a varying output indicative of a varying distance between the piston drive member and the piston. A controller (30) coupled to the proximity sensor is configured to control movement of the piston drive member from the loading position to the loaded position and stop movement when the controller based on input from the proximity sensor system determines that the loaded position has just been reached. By this arrangement it is prevented that a drug-filled cartridge is pressurized during the loading and initializing procedure.
