Abstract: An example device including a laser source for generating a laser pulse, a scanner for mounting the laser source, and a motion detector for detecting a motion of the scanner when the laser pulse scans an object. The motion detector includes an optical sensor for generating an optical signal based on the motion of the scanner, and a controller. The controller determines a movement of the scanner and disables the laser source when the scanner ceases to move.

Abstract: In one example, a processor readable medium has instructions thereon that, when executed by a processor, cause a system to detect a change in electrical conduction of a liquid moving at an interface between two surfaces and determine a conductivity of the liquid based on the detected change in conduction.

Abstract: In some examples, an assembly for a footwear includes a cell comprising a housing structure, the cell comprising a first chamber to contain a fluid. The assembly further includes a port and a vibrator responsive to activation to cause a reduction in fluid flow through the port between the first chamber and a second chamber by changing a characteristic of the fluid in the port.

Abstract: An example system comprising a pressure sensor array, a proximity sensor comprising circuitry to sense an object approaching the pressure sensor array based on a change in a resonance frequency of the proximity sensor, and a controller to receive from the proximity sensor the sensed change in the resonance frequency and designate the pressure sensor array as active responsive to the sensed resonance frequency being below a threshold or inactive responsive to the sensed resonance frequency being above the threshold, wherein a data transmission rate of the active pressure sensor array is greater than a data transmission rate of the inactive pressure sensor array.

Abstract: Reducing print quality defects can include printing a pattern with an offset printing device having a binary ink developer roller, determining a variation for a hue shift of the printed pattern; and varying gain in a feedback loop of a servo motor coupled to the binary ink developer roller to reduce the variation.
