摘要:
An improved hybrid connector for rapidly, reliably, and reversibly making mixed optical and electrical connections has a plug (103) with one or more centrally located fiber-containing optical ferrules (108) and one or more peripheral electrical contacts (109), and second, a socket (105) with interior electrical contacts (115) and a fiber-bearing central floating optical connector (225). Insertion and rotation of a shaft (107) of the plug into a bore (201) of the socket connects the respective electrical contacts of the shaft and socket, and nearly-simultaneously couples the respective optical fibers of the plug ferrule and socket connector, thus creating a rapid, reversible, and low-cost hybrid connection optimized for both the electrical and optical requirements of a mixed optical and electrical connection.
摘要:
A method and improved apparatus for detecting leaks in pressurized pipeline systems, which compensate for the thermally induced volume changes of the liquid in the line during a test that are produced by both the nonlinear changes in the mean temperature of the liquid and the pressure-induced perturbations of the temperature of the liquid.

摘要:
An improved combination light source (103) comprises a combination of a solid-state white LED source (105) to illuminate a target with continuous, broadband illuminating light (114), and a second, additional light source, as an integrated system. While the white LED provides illumination, the second light source provides for medical, industrial, or laboratory analysis. A combination solid-state and second illuminator integrated with one or more detectors advantageously allows for a more compact, less heat producing, and more energy efficient manufacturable device, and further facilitates integration of the illuminator and detector into a device or system. Methods of use are also disclosed.
摘要:
An improved hybrid connector for rapidly, reliably, and reversibly making mixed optical and electrical connections has a male plug with one or more centrally located optical fibers centrally located inside an elongated shaft of a male plug, and one or more electrical contact elements are located on the peripheral surface of the shaft, and a socket with electrical contacts, and a floating optical connector. Insertion of the elongated shaft into the socket connects the electrical contacts of the shaft and socket and couples the fibers of the shaft with optical fibers in the floating optical connector.
摘要:
A method of detecting a leak in a pressurized pipeline system, in which a measurement is performed to determine the difference in the rate of change of pressure due to a leak between one pressure level and at least one other pressure level, after compensation has been made for thermally induced changes in the pressure.
