Patent number: 9625313Abstract: An optical meter includes a force member to receive a force and a reflector disposed on the force member to receive radiation and to communicate a pressure of the radiation to the force member. The reflector includes a reflective surface, and the force member is configured to be displaced in response to receiving the force comprising the pressure. The optical meter is configured to measure a power of the radiation, an energy of the radiation, or a combination thereof based on the pressure. A process for measuring a property of radiation includes receiving radiation by the reflector, reflecting radiation from the reflective surface, communicating a pressure from the reflector to the force member, and displacing the force member.Type: GrantFiled: June 24, 2014Date of Patent: April 18, 2017Assignees: THE UNITED STATES OF AMERICA, AS REPRESENTED BY THE SECRETARY OF COMMERCE, SCIENTECH INCORPORATEDInventors: John Lehman, Paul Williams, Robert Lee, Frank Maring

Publication number: 20070286555Abstract: An optical connector system joining waveguides in two printed circuit boards. A flexible optical conductor is connected at one end to one of the boards. The flexible conductor includes at its free end an alignment structure that provides a separable, low loss interface to an alignment structure coupled to the waveguide on the other board. The ends of the waveguides are enclosed in housings that protect the waveguides from abrasion and contaminates, but expose the waveguides when the connectors mate.Type: ApplicationFiled: April 19, 2007Publication date: December 13, 2007Inventors: Sepehr Kiani, John Lehman

Publication number: 20060002659Abstract: An optical connector system assembled from modular components. These components include connector modules that position ferrules for mating and providing fine alignment to fibers. The modules are assembled to support members to form connectors of various sizes. Mounting modules are attached to the support members. Various shaped mounting modules are provided, allowing connectors to be assembled for various configurations, such as a matrix configuration, a parallel board-to-board configuration or a panel mount configuration.Type: ApplicationFiled: July 1, 2004Publication date: January 5, 2006Applicant: Teradyne, Inc.Inventors: Sepehr Kiani, Richard Roth, John Lehman

Publication number: 20050069262Abstract: An optical interconnection system, particularly useful in a backplane arrangement in an electronic assembly. The interconnection system includes “dual-use” protective covers for protection from damage and/or cleaning within backplane and daughter card style connectors. The protective covers are modular for easy use. Some versions contain adhesive members that can remove contaminates from various portions of the connector assembly. The protective covers can be inserted into a backplane connector of an electronic assembly using a tool or as part of a “dummy board.Type: ApplicationFiled: September 26, 2003Publication date: March 31, 2005Applicant: Teradyne, Inc.Inventors: Richad Roth, Joseph George, Sepehr Kiani, John Lehman, Mark Vitello

Patent number: 6843896Abstract: The invention encompasses a method and apparatus for producing high-purity metals (such as, for example, high-purity cobalt), and also encompasses the high-purity metals so produced. The method can comprise a combination of electrolysis and ion exchange followed by melting to produce cobalt of a desired purity. The method can result in the production of high-purity cobalt comprising total metallic impurities of less than 50 ppm. Individual elemental impurities of the produced cobalt can be follows: Na and K less than 0.5 ppm each, Fe less than 10 ppm, Ni less than 5 ppm, Cr less than 1 ppm, Ti less than 3 ppm and O less than 450 ppm.Type: GrantFiled: June 14, 2002Date of Patent: January 18, 2005Assignee: Honeywell International Inc.Inventors: Guangxin Wang, Daniel M. Hydock, John Lehman

Patent number: 5884717Abstract: A swing arm assembly (10) for use in converting a motorcycle into a tricycle is described which includes a rear axle assembly (12) and a swing arm (14) having a first end (16) and a second end (18). The first end (16) is adapted for pivotal attachment to a motorcycle chassis. The swing arm (14) is detachably secured to the rear axle assembly (12). A pair of axle engaging members (22) are secured in spaced relation to the rear axle assembly (12). A pair of telescopically extendable/retractable members (24) are provided having a first end (26) and a second end (28). The first end (26) of each telescopic member (24) is telescopically received in one of the axle engaging members (22). The second end (28) of each telescopic member (24) is attached to the second end (18) of the swing arm (14) after a continuous belt for a belt drive is slid loosely into position. The telescopic members (24) are telescopically extendable once the continuous belt is in position to place the belt in proper operating tension.Type: GrantFiled: September 3, 1996Date of Patent: March 23, 1999Inventors: John Lehman, Larry David Strilchuk

Patent number: 5529141Abstract: All improvement in a kit for converting a motorcycle to a tricycle is described. The kit includes a pair of swing arms having a first end and a second end. Axle couplings are provided at the first end of each swing arm whereby the swing arms are secured to an axle which supports two wheels. Pin receiving couplings are provided at the second end of each swing arm whereby the swing arms are pivotally secured by pins to a motorcycle frame. The improvement is characterized by swing arms having a top surface and a bottom surface. The axle coupling and the pin receiving coupling extend vertically from the top surface of the swing arms. The top positioning of the axle couplings and the pin receiving couplings leaves the majority of the top surface of the swing arms dropped below the level of the original floor boards of the motorcycle. The swing arms can pivot as intended without their movement being impeded by the original floor boards.Type: GrantFiled: May 2, 1994Date of Patent: June 25, 1996Inventors: John Lehman, Larry D. Strilchuk
