摘要： The present document describes an optical interconnect module for interfacing optical fibers. An optical interconnect module in accordance with an embodiment comprises a casing including a projection and an optical sub-assembly including an interlock portion for receiving the projection of the casing. The optical sub-assembly carries a plurality of optical fibers, and couples face to face with an optical cable assembly for aligning the corresponding fibers together. The optical cable assembly is usually provided in an optical cable connector, along with a spring which compresses when the optical cable connector is inserted in the optical interconnect module. The pressure provided by the spring is transmitted to the optical sub-assembly. The optical sub-assembly applies this pressure to the projection received in the notch thereof for maintaining a tight engagement with the optical cable assembly. With this arrangement it is possible shorten the optical sub-assembly, save circuit board space and reduce the length of the optical fibers, which results in optical interconnect modules which may achieve high speed short-reach optical data connectivity in a small form factor and at low cost.

摘要： A Heads-Up Display system which displays an attitude reference to pilots in order to provide a reference display system as a primary flight instrument. The Heads-up Display system uses a pitch ladder system based on Euler angle data which eliminates the erratic motion or "flip-flop" of the typical pitch ladder which is inherent and unavoidable when pitching near plus or minus 90.degree., by utilizing a flexible graphics display which presents the pilot with a heads-up view as if he were located inside and at the center of an imaginary sphere which has heading and pitch angle information marked on its inner surface. The display of appropriately curved bars as opposed to a straight bar pitch ladder for attitude reference more realistically depicts to the pilot the aircraft situation relative to the outside world. This presentation is more easily and more reliably interpreted by the pilot and simplifies the recognition and recovery from unusual attitudes. In addition, ground track, yaw rate, turn rate information is available over the entire HUD field-of-view, thus there is no need for the pilot to redirect his attention away from his primary point of interest, the velocity vector, to obtain heading and track information. Appropriate equations are evaluated to obtain line-of-sight angles from the aircraft longitudinal axis to the desired pitch and heading points on the pitch ladder display. Such equations are solved by computer techniques for a sufficient number of intersecting points to complete the display and the graphics hardware connects the points to form the segments of the pitch ladder which represent the imaginary lines on the sphere and displays the same in the pilot's field-of-view.
