Abstract: Head up displays are provided. A head up display may have a base adapted for mounting to a firearm; a window positioned by the base so that a user of the firearm can observe a field of view through the window; an illuminator operable to generate a divergent illumination light; a light valve configured to modulate the divergent illumination light in accordance with an image provided by an image generator; and a collimating optic in an optical path between the light valve and the window that substantially collimates the image modulated illumination light. The window reflects at least a portion of the image modulated collimated light so that the observer observes the image substantially in focus with objects in field of view. Images presented may include data and images, including but not limited to thermal images.

Abstract: An electroluminescent lighting system includes an electroluminescent encapsulated and protected inside a solid wall mounting channel. The mounting channel is typically plastic. The mounting channel may itself be printed on its outside display surface, or it may protect a printed surface inside its channel.

Abstract: A packaging assembly for a high-speed vertical-cavity surface-emitting laser (VCSEL) mainly applies a lens assembly consisted of several prisms to split a laser beam emitted by a VCSEL element so as to guide a small portion of the laser beam back to a monitor photodiode (MPD) and the rest of the laser beam to travel away along an optical axis. Such a spectacular design of the lens assembly can not only relieve the VCSEL element from a position right under the optical axis, but can also reduce signal loss by shorting a length of a bonding wire for a corresponding pin through disposing the VCSEL element further close to the corresponding pin. Thereupon, a defect of lights reflected from a lens or a translucent plate on a cap can be substantially improved.
