摘要:
A patch cord including a connector attached to an end of an electrical cable. The connector includes a single-piece attachment member having a management section, a boot, and collar including a retention arrangement. Certain types of retention arrangements include one or more teeth that protrude inwardly from the collar to bite into at least an outer jacket of the electrical cable.

A receptacle block defines one or more sockets at which plugs may be received. Each socket contains a first set of contacts and a second set of contacts. Each socket also includes a sensing contact that interacts with the second set of contacts to close an electrical switch. For example, the sensing contact can interact with an arm extending from one of the contacts of the second set. Closure of the switch can be detected and interpreted to indicate that a plug has been received at the respective socket.
摘要:
A fixture and cutter tool is described. The fixtures includes features that enable a work piece to be easily mounted and removed by a rotation motion of the work piece onto the top of the fixture. The system includes the fixture and a cutter tool to prepare the work piece for use with the fixture.
摘要:
A cable management frame assembly comprising a collapsible frame chassis and a plurality of positionally configurable cable management fixtures that can be affixed to the frame chassis without the use of tools or additional hardware such screws, nuts or bolts. A panel mount allows patch panels and equipment to be mounted to the frame chassis without the use of tools or additional hardware.

A one-box system and process for controlling Internet usage by users on a network. The system controls usage by combining two or more of the following functions into a single operating unit: 1) monitoring and logging internet access on a user and/or work station basis; 2) preventing or authorizing access on a user and/or work station basis to ULR's (or groups of URL's) that have been previously designated an inappropriate or appropriate, respectively, for that user or work station; 3) preventing or authorizing the downloading of files with any pre-designated file extension to any user or workstation; 4) blocking of peer-to-peer access of any pre-designated Internet file-sharing or other service (such as Kazaa, RealPlayer, AOL Instant Messaging, etc); 5) periodically or immediately alerting a designated representative of the attempt by any user or work station to access of pre-determined inappropriate site or file; 6) allowing remote review of the Internet activity log for any user by anyone (such as a student's parents) with knowledge of that user's log-in information (i.e., name and password); and 7) caching downloaded Internet objects for subsequent in-network retrieval. The system and process of this invention can also be configured to perform the traditional firewall function as well.
摘要:
A modulating retro-reflector (MRR) can be configured to provide a large field of view. The MRR can include a solid corner cube reflector (CCR) manufactured of a material having a high index of refraction at the desired operating wavelength. CCRs made from high index materials such as InP or Si, have an index of refraction of approximately 3.48 at an operating wavelength of approximately 1550 nm and can provide a conical Field of View (FOV) of greater than ±60 degrees compared to less than ±30 degrees for CCRs made from BK-7. Each CCR can include one or more elements configured to modulate an optical signal incident on the CCR. A retro-modulating transponder can use fewer large FOV MRRs to support communication over a predetermined incident optical span compared to narrower FOV MRRs resulting in lower cost, smaller size, weight and power requirements.
摘要:
A tooling fixture that provides a self-centering vise to hold a work piece is described. The design provides a means to allow a centering adjustment of the clamping surfaces that is integrated into the central support structure for the threaded spindle.
摘要:
A connector arrangement includes a plug nose body; a printed circuit board positioned within a cavity of the plug nose body; and a plug cover that mounts to the plug nose body to enclose the printed circuit board within the cavity. The printed circuit board includes a storage device configured to store information pertaining to the electrical segment of communications media. The plug cover defines a plurality of slotted openings through which the second contacts are exposed. A connector assembly includes a jack module and a media reading interface configured to receive the plug. A patch panel includes multiple jack modules and multiple media reading interfaces.
