Abstract: A multi-functional wireless headset may include a heart rate sensing assembly configured to detect heart rate data of a wearer of the headset, and a wireless communication unit configured to communicate heart rate data to a gateway device.

Abstract: An electroluminescent display contains an array of dynamically addressable pixels. The pixels are arranged on one side of a carrier substrate. Conductive vias in the substrate are electrically connected to each of the pixels. Each pixel consists of a bottom electrode that is coupled to a via, an electroluminescent material, and a dielectric material. A common top electrode is disposed on the dielectric material. A driver circuit conductor or connector is situated on the other side of the substrate and is electrically coupled to each of the conductive vias and to the common top electrode, so that each pixel can be individually addressed to illuminate the electroluminescent material on individual pixels.

Abstract: An electroluminescent display device contains an electroluminescent phosphor sandwiched between a pair of electrodes and a graphic arts element. The device is fabricated by bonding a generic electroluminescent base laminate containing an electrode and an electroluminescent layer, to a custom graphic arts film containing a graphic element and a corresponding electrode. The generic electroluminescent base laminate is made at a first location or time, and the custom graphic arts film is made at a second location or time.

Abstract: An electroluminescent display device is fabricated by creating a generic electroluminescent base laminate or precursor containing an base electrode and an electroluminescent layer. A custom graphic arts film or precursor containing a graphic element and a corresponding electrode is also fabricated. The two precursors are then bonded together using an adhesive to create the customized EL display, so that only the sections of the electroluminescent display device that are associated with the corresponding electrode on the graphic arts film emit light.
