Abstract: A wearable fitness heart rate monitor comprising an earpiece comprising a sensor unit having a light emitting element and a light receiving element, wherein a portion of an ear is positioned therebetween, wherein the light emitting element emits light into the portion of the ear positioned intermediate the light emitting and light receiving elements, the light receiving element detects the intensity of light passing through the portion of the ear positioned intermediate the light emitting and light receiving elements, and the sensor unit comprises means for outputting an electrical signal based thereon; processor means, coupled to the sensor unit, for processing the electrical signal and determining a heart rate therefrom; and a display, coupled to the processor means, for displaying the heart rate.

Abstract: An electronic device comprising a secondary display made up of a plurality of display segments each of which is made up of a multilayered assembly comprising a transparent substrate having a first and a second surface; a transparent electrically conductive layer formed on the second surface of the transparent substrate; an electroluminescent layer formed on the transparent conductive layer; an insulating layer formed on the electroluminescent layer; and an electrically conductive layer formed on the insulating layer; and including means for selectively illuminating electroluminescent layers of each of the plurality of display segments, wherein light emanating from the illuminated electroluminescent layers during an illuminated condition passes through the transparent substrate; whereby secondary information is provided by the selected illumination of the electroluminescent layers.
