Abstract: A self-laminating rotating cable marker label is constructed of a transparent film having a first adhesive area, an adhesive-free smooth area, and a second adhesive area. A print-on area forms one side of the transparent film, the print-on area adapted to receive indicia identifying the cable about which the marker label is applied. A perforation extends across the transparent film providing a line of separation of the transparent film. When wrapped around a cable, the second adhesive area overlies the print-on area such that the cable identifying indicia is visible through the transparent second adhesive area. As the transparent film is wrapped around the cable, the first adhesive area adheres to the cable. The remainder of the transparent film is rotated, breaking the perforation, whereby the smooth area of the film in contact with the cable provides smooth rotation of the label around the cable.

Abstract: An identification and authorization system is provided that utilizes a national ID database and a number of application-specific databases. The national ID database contains unique individual ID numbers linked to unique biometric codes. The application-specific databases contain an applicable portion of the same unique individual ID numbers that are contained in the national ID database. To complete a transaction, a credential such as an ID card is scanned and a biometric scan of the individual is completed. The transaction information and the individual ID number is sent to the appropriate application-specific database. Verification of identity is completed at the national ID database, which compares the biometric code of the biometric scan with the biometric code linked to the unique individual ID number. A response from the application-specific database and a response from the national ID database is sent to the scanning location.

The spillover fitting includes fitting walls and a floor positioned between the fitting walls. The floor has an extension flange that extends into the lateral trough. The spillover fitting also includes a containment member that extends from the extension flange. The containment member is positioned over the lateral trough to contain cables routed out of the lateral trough into the spillover fitting.

Abstract: A network cable jack includes a printed circuit board (PCB) for balancing both inductive and capacitive coupling. Using a PCB allows compact trace paths to be formed without significantly increasing manufacturing costs. By including on each trace path two distinct inductance zones separated by a neutral zone, significant gains in degrees of freedom are achieved for designing PCB trace patterns in which a pair of inductive coupling zones jointly offset the inductive coupling caused by a specification plug and the jack contacts, both in magnitude and phase angle. Further, using distinct inductance zones offers more freedom regarding the placement of capacitive plates for use in capacitance balancing as well as the placement of terminals and insulation displacement contacts. Although the magnitude of a capacitive coupling is determined by the length of the capacitor plates parallel to current carrying traces, the approach allows capacitive and inductive coupling to be balanced independently.

Abstract: A documentation system for a network is provided. The system has a data port and a destination device, each of which includes an electronic module with an identification code. A source device sends query signals along a network path addressed to the data port and destination device. Each of the data port and destination device electronic module responds to the query addressed to the data port and destination device by transmitting its identification code to the source device. A processor and switch in communication with the source device direct the source device to send the query signals and to interpret the responses. The data port and destination device electronic modules are powered by a local power source and patch cord. A patch cord may be adapted to provide power from the local power source both to the destination device and to the data port.
