Title: Cable entry panel for double twist bunching machine
Inventor: WENG WEN-BIN
IPC: H01B13/00
Filed: 2001-03-21
Granted: 2002-01-21
Abstract: The present invention provides a cable entry panel for double twist bunching machine, which is employed to bunch a plurality of wires or long fibers. The cable entry panel includes a main body and at least a guiding ring located on the panel for guiding the wires and long fibers to pass the guiding ring along the longitudinal direction of the main body. The present invention is characterized in that the main body is made of aluminum-based composite material, which includes an aluminum-contained material and ceramic particles by volume of 5% to 40%. Since the specific weight of the cable entry panel of aluminum-based composite material is small, the high rotating speed while operating may increase the yield of wire bundles or long fiber bundles. Small deformation caused by centrifugal force while the high-stiffness and high-flexibility material operating may avoid phenomenon of breaking of the copper wire. Otherwise, the material has excellent wear-resistance due to containing ceramic particles. Furthermore, the material is advantageous in being easily machined.

Low frequency acoustic signals that are incident on the membrane cause the membrane to move and amplify the acoustic signals within the resonant cavity. The sensor provides information concerning physiological conditions, such as respiration and cardiac activity. The sensor in a physiological condition monitor does not need to be directly coupled to the skin of the person being monitored. The physiological condition monitor simultaneously provides information concerning cardiac activity, and respiration activity, and the movement and position orientation of the monitored person's body.

Granted: 2004-02-21
Abstract: An optical coupling element for use in large numerical aperture collecting and condensing systems. The optical coupling element includes a curved surface such as a lens at the output of a tapered light pipe (TLP). The TLP in combination with the curved surface alters the divergence angle and the area of the light exiting the curved surface. Electromagnetic radiation emitted by a source is collected and focused onto a target by positioning the source of electromagnetic radiation substantially at a first focal point of a primary reflector so that the primary reflector produces rays of radiation reflected from the primary reflector that converge at a second focal point of the secondary reflector. The optical coupling element is positioned so that its input end is substantially proximate with the second focal point of the secondary reflector. The converging rays of radiation reflected from the secondary reflector pass through input end and are transmitted towards the curved surface, where their divergence angle and area are adjusted.
