Abstract: There is disclosed a system and method for testing and orientation of components for assembly, including a component selection tester for testing, prior to assembly, the correct selection of a desired component. The component selection tester includes at least one sensor configured to provide an indication of correct selection only if the desired component is placed for testing on the at least one sensor in a correct orientation for assembly. The sensors may be configurable to provide the indication of correct selection in dependence upon a specified orientation required for assembly. The sensors may also be configurable to test a characteristic of the component. In an embodiment, the component is an electronic component, and the sensors are electrical contacts.

Abstract: An apparatus for irradiation of a fluid with UV light includes a tubular body consisting of UV-permeable material. The body includes a fluid chamber and openings for passage of fluid. A UV source is provided to subject the chamber to the UV light. A wiper is centrally supported in the body to clean the inner surface of the body. Light baffles define an irradiated section of the chamber to prevent light penetration beyond the irradiated section while permitting the fluid to flow through. The apparatus is provided as a component in a housing having a modular design. The modules include a back cover for surface mounting. The body is mounted to the back cover. An inner cover is attached to the back cover. The inner cover includes the UV source and modular electronics. A front cover is attached to the inner and back cover.

Abstract: An array of disks facing a viewing direction is composed of disks rotatable about an axis approximately perpendicular to the viewing direction between alternating orientations where light and dark surfaces are respectively displayed in the viewing direction. There is provided a row of LEDs located forwardly of the array and out of the normal viewing path located to illuminate the disks of said array. Masking means prevents direct illumination from said LED's being visible in the viewing direction. In a further variant the disks' light surfaces contain a fluorescent component and the LEDs are selected to provide radiation including UV spectra.

Abstract: An array of disks faces a viewing direction is composed of disk's rotatable about an axis approximately perpendicular to the viewing direction between alternating orientations where bright and dark sides are respectively displayed in the viewing direction. There is provided a row of LED's located forwardly of the array and out of the normal viewing path located to illuminate the disks of said array. Masking means prevents direct illumination from said LED's being visible in the viewing direction.
