ABSTRACT:
An apparatus for providing a display of information or a source of light to a viewer or an object along the line of sight between a user of the apparatus and the viewer or object without preventing the user's normal vision. The apparatus generally includes an element which provides visible images to the viewer, a member which blocks the visible image from the user, and an activating device which provides oscillating activation signals to the imaging element and the blocking member. The apparatus may also include prisms associated with each other to reflect certain images or light to the viewer or object.
