Abstract: A system and method for integrating a production line process control system (PCS) with production line machine controllers to record data about processes completed on a production line. The PCS receives data from line controllers regarding processes that are completed on each part. Process data including process order data is stored by the PCS and used to instruct line controllers on whether a particular part should be accepted for machining or handled in another way. Rejected parts are flagged electronically so when they arrive at a subsequent line controller, they are directed to a chute containing parts removed from the production process. The PCS and line controllers exchange data about each part and applicable processes as it proceeds through production. The PCS records the data to develop a complete part history. The PCS integrates with a plant quality and tracking system that records the historical data.

Abstract: A method and apparatus are provided for testing the adhesive strength of a bond between an adhesive, a coating such as paint, or some other material, and an underlying substrate to which the test substance is bonded. The coating to be tested is applied atop the substrate in a smooth, continuous layer. An aperture is formed through the substrate and the test substance. A thin film patch is positioned atop an area of the test substance directly above the aperture. The film extends beyond the perimeter of the aperture and resides in contact with the test substance. The test substance is scored about the perimeter of the thin film patch. A thin plate which maintains its elastic property with only minor yielding during the test is bonded to the test substance by means of a layer of high-strength adhesive interposed between the plate and the test substance.

Abstract: A head-up display system for an aircraft has a display unit which projects a display of symbology representing the aircraft flight parameters onto a separately mounted partially-transparent reflector positioned in front of the aircraft pilot, so that the pilot sees an image of the display against the external scene. The display unit has a sensor which receives an image of the display via the reflector. The sensor responds to displacement of this image from a reference established with respect to the display unit, caused by movement of the reflector relative to the display unit, and the display is correspondingly modified to compensate for such movement. The display unit may include a cathode-ray tube for providing the display which can be modified by adjustment of the deflection of the cathode-ray beam. In this case the reference established with respect to the display unit may be an instantaneous point image of the cathode-ray beam.

Abstract: A head-up display system in a military aircraft provides projection of flight and weapon-aiming information into the pilot's line-of-sight through a partially-transparent reflector. The pilot operates a button firstly when he recognizes a target viewing through the display and then again when he fixes his eye on an aiming marker in the display. On each occasion of button operation a measure of his eye position is entered into the system to derive coordinates of the identified target related to the marker position in the display, for generation of the appropriate shifts to move the marker into register with the identified target. The measure of eye position is provided in each case by analysis of video-signal waveforms derived by a vidicon camera that is carried on the pilot's helmet and scans reflection in the helmet-visor of the pilot's eye as illuminated, also by reflection in the visor, from an infra-red source.
