The conforming snug fitting towel acts as a cover over any size or brand exercise equipment upholstery padding thereby providing a perspiration and bacteria barrier. The conforming elastic border prevents the towel from moving or slipping off said equipment upholstery padding. Also, prospective user can use the towel cover to wipe body perspiration from skin.

Abstract: A portable system (20) for testing an electro-optical guidance assembly (22) includes an electro-optical test unit (40) with at least two sources of electromagnetic energy at different wavelengths for selectively illuminating the guidance assembly. The electro-optical test unit (40) is mounted within a frame (56) that can be part of a wheeled cart (50). The system (20) further includes one or more of: an adjustable fixture (84) for supporting a guidance assembly (22) for testing, a processor unit (42) for controlling the electro-optical test unit (40), a power supply unit (44) for providing electrical power to the electro-optical test unit (40) and the guidance assembly (22), and a leak test unit (46) for generating a vacuum in the guidance assembly (22) or for pressurizing the guidance assembly (22) with an inert gas to test for leaks.
