Abstract: The disclosure relates to a computer controlled imaging system involving a digital image processing and display system which has the ability to compose and construct a display scene from a library of images with sufficient processing speed to permit real-time or near real time analysis of the images by a human operator or a hardware/software equivalent thereof. An unique method of mapping a digital input image to a viewing plane in both linear and perspective modes is disclosed.

Abstract: A fiber optic vibration sensor for detecting vibrations of a reflecting surface located externally of the sensor is disclosed which includes a transparent body, source and return optic fibers fastened to the body, a light collimating lens which forms light emanating from the source fiber into a column which extends in a predetermined viewing direction relative to the body. The sensor is positioned relative to the reflecting surface so that the column strikes the reflecting surface and is reflected back through the lens to a focal point in the vicinity of the end of the return optic fiber.

Abstract: The disclosure involves a coefficient-of-performance (COP) diagnostic method involving the use of novel algorithms for determining performance manifested faults of vapor compression type refrigeration systems.
