ANTI-THEFT MERCHANDISE HOOK

An anti-theft merchandise hook that includes a top wire connected to a housing at a first end of the top wire, and to a mounting portion, used to mount the anti-theft merchandise hook to a stationary surface, at a second end of the top wire opposite the first end. A bottom wire is attached to the mounting portion and extends from the mounting portion towards the housing. The bottom wire is configured to hold retail merchandise. A hanger is at least partially disposed within the housing. The hanger is configured to move between a closed position in which the hanger abuts the bottom wire, and an open position in which the hanger is spaced some distance from the bottom wire. A motor is configured to move the hanger between the closed position and the open position.

Optical ferrule having compound stops

An optical ferrule comprises first and second compound stop features respectively disposed at opposing sides of the optical ferrule. Each compound stop feature has upper and lower contact surfaces. The lower contact surface is offset below the mating surface of the optical ferrule along a thickness axis perpendicular to the mating surface. The upper contact surface is offset above the mating surface along the thickness axis. The lower contact surface is offset forward from the upper stop surface along a mating direction of the optical ferrule. A connecting surface connects the upper contact surface and the lower contact surface.

PRECISION NON-CONTACT CORE IMAGING OF FIBER OPTIC ASSEMBLIES

A method, system, and computer program product for determining a core-to-ferrule offset of a ferrule for a fiber optic connector. A reference ferrule is physically aligned with a core imager by positioning the reference ferrule so that edges of the reference ferrule in a plurality of profile images are aligned with fiducial markers in the images. The reference ferrule is incrementally rotated about its longitudinal center access, a core image captured at each rotational angle, and a reference core-to-ferrule offset determined based on the core images. A test ferrule is physically aligned with the core imager by positioning the test ferrule so that edges of the test ferule are aligned with the edges of the reference ferrule in a plurality of profile images. The core-to-ferrule offset of the test ferrule is then determined based on an offset between the test and reference cores in a composite core image.

RELATIVE MODE TRANSMISSION LOSS MEASUREMENT OF A CONNECTORIZED FIBER OPTIC CABLE

A method and system for measuring signal loss in a fiber optic cable. The tail ends of reference and test fiber optic cables are illuminated with a diffuse light. The head end of each of the reference and test fiber optic cables are positioned in a measurement area. A core imager captures an image of the core of each head-end while it is in the measurement area. Reference and test radiant fluxes emitted from the reference and test head-ends are determined from the respective core images. The relative signal loss of the test fiber optic cable is then determined by comparing the test radiant flux to the reference radiant flux.

Fiber optic micro connector

A micro connector kit including a ferrule assembly, an optical sub-assembly (“OSA”) and a micro connector. The ferrule assembly is coupled to an optical fiber and includes a ferrule. The OSA can receive an electric signal and transmit an optical signal or receive an optical signal and transmit an electric signal. The OSA includes a receptacle sized and shaped to receive the ferrule of the ferrule assembly to form an optical connection between the ferrule assembly and the OSA. The micro connector secures the optical connection between the ferrule assembly and the OSA. The micro connector includes a micro connector housing that forms a direct, mating connection with the OSA to secure the optical connection between the ferrule assembly and the OSA. The connection is made using only a very small space, allowing more ferrule assembly and OSA connections to be made in a smaller area.
