Patent number: 10782494Abstract: An opto-electronic contact, method and connection system can utilize an active opto-electronic converter configured for removable optical engagement with an opposing contact. A barrel housing defines an interior cavity to capture the converter in the interior cavity for external optical engagement to the opposing contact via the first barrel opening for relative movement of the converter axis along the elongation axis, transverse thereto, and oblique thereto to accommodate mating tolerances responsive to engaging the opposing contact. A flexible circuit board assembly can be used to externally electrically interface the converter.Type: GrantFiled: August 11, 2019Date of Patent: September 22, 2020Assignee: Glenair, Inc.Inventors: Ronald T.

Patent number: 9664868Abstract: A connector insert arrangement, an active optical cable and methods are described. The connector insert is receivable in a connector housing for removable engagement with a complementary connector. Dielectric inserts each support one or more electrical contacts for access by the complementary connector and each electrical contact is selected as one of a contact pad and a spring probe pin for electrical contact with a complementary spring probe pin and complementary contact pad, respectively, in the complementary connector. A ground body supports the dielectric inserts to maintain a characteristic transmission line impedance along each of a plurality of high speed data paths such that each high speed data path serves as an independent transmission line structure that provides a data transfer rate of at least 1 gigabit per second. An active optical cable is described that can be hermaphroditic.Type: GrantFiled: June 17, 2015Date of Patent: May 30, 2017Assignee: Glenair, Inc.Inventors: Ronald T.

Patent number: 9052238Abstract: An apparatus for analyzing, identifying or imaging an target including first and second laser beams coupled to a pair of photoconductive switches to produce CW signals in one or more bands in a range of frequencies greater than 100 GHz focused on and transmitted through or reflected from the target; and a detector for acquiring spectral information from signals received from the target and using a multi-spectral heterodyne process to generate an electrical signal representative of some characteristics of the target. The lasers are tuned to different frequencies and a frequency shifter in the path of one laser beam allows the terahertz beam to be finely adjusted in one or more selected frequency bands.Type: GrantFiled: September 20, 2013Date of Patent: June 9, 2015Assignee: Emcore CorporationInventors: Ronald T.
