Abstract: An electronic device includes a marker with a pattern of marks encoding product information of the electronic device. The pattern includes first marks having a first material with a first isotopic ratio of an element, and second marks having a second material with a second isotopic ratio of the element different than the first isotopic ratio.

Abstract: In an example implementation, a touch-sensitive illuminating display includes a transparent flexible touch layer, a transparent top conductive layer adjacent the flexible touch layer, a bottom conductive layer, and an electroluminescent layer and variable-thickness dielectric layer sandwiched between the top and bottom conductive layers. Pressure against the flexible touch layer is to reduce the dielectric layer thickness and bring the top and bottom conductive layers closer together, causing the electroluminescent layer to emit light where the pressure is applied.

Abstract: An annealing device may include an array of thermal heaters, each thermal heater comprising a resistive element formed into a cavity and wherein each of the thermal heaters within the array of thermal heaters are selectively activated to anneal an annealable material deposited into the cavities.
