Abstract:
A modular power distribution system includes using power extension modules and power distribution modules. The power extension modules are configured to route inputted power to another power extension module or a power distribution module. The power distribution modules are configured to route power from a power extension module to one or more racks or cabinets in a data center.
Abstract:
An absence of voltage indicator has an isolation circuit, an FM modulator attached to the isolation circuit, a reference oscillator, and a mixer attached to the reference oscillator and the FM modulator, wherein the output of the mixer is the difference of the two signals. In one embodiment, the FM modulator includes a variable capacitor which varies in response to a voltage in parallel to a fixed capacitor and an inductor in parallel to the capacitors.
Abstract:
A voltage display module for a voltage indication device has a well body, communication cable, cap, and battery shuttle. The well body is secured to the door of the electrical enclosure. The communication plug of the communication cable is secured to the well body. The cap is removably secured to the well body and is accessible to a user from outside the enclosure. The battery shuttle is housed within the well body and has a communication jack secured to one end. The communication jack is configured to engage the communication plug when the battery shuttle is fully inserted and configured to be electrically isolated from the plug when the battery shuttle is partially withdrawn.
Abstract:
The present invention generally relates to the field of network communication, and more specifically to networks for crosstalk reduction/compensation and communication connectors which employ such networks. In some embodiments, the present invention employs an orthogonal network implemented within a communication jack to compensate for crosstalk which occurs within a communication plug and at the plug/jack interface.
Abstract:
The present invention attempts to reduce the thermal resistance with the use of heat-transfer devices (e.g., vapor chambers) placed directly on the heat-generating components in IT equipment and the integration of a cold plate within the cabinet. In some embodiments, the present invention is a thermal management system comprising a cabinet-side thermal management system and a server-side thermal management system using moveable thermal components.
Abstract:
The present invention provides an automated system for asset tracking and management and utilizes near field Radio Frequency IDentification (RFID) technology. RFID tags are attached to the assets, and RFID antennas (and coiTesponding readers) are strategically located in close proximity to read the tags. As applied to a rack or cabinet, near-field antennas are mounted along one of the mounting posts at each rack unit location such that when a piece of equipment (rack mounted or rail mounted) is installed at a particular rack unit space, the tag will be read and registered in an RFID management system. A magnetic field shaping arrangement ensures that crosstalk between adjacent rack positions is prevented. Ferrite elements are used to control the magnetic field.
Abstract:
An intelligent network patch field management system is provided that includes active electronic hardware, firmware, mechanical assemblies, cables, and software that guide, monitor, and report on the process of connecting and disconnecting patch cords plugs in an interconnect or cross-connect patching environment. RFID tag integrated chips are used in some embodiments of the system to allow for detection of patch cord insertion and removal at switch ports. RFID tags may also be used to detect users and control access to the network based on the users' levels of authorization. Network access can also be controlled at the outlet jack level. The system is capable of monitoring patch cord connections to detect insertions or removals of patch cords or plugs. In addition, the system can map entire networks.
Abstract:
A communications cable is provided with a matrix tape that attenuates alien crosstalk when cables run near one another. The matrix tape is provided with conductive segments. The conductive segments are preferably provided on two layers of the matrix tape. In one embodiment, the conductive segments are attached to a film with an adhesive. A barrier tape is preferably provided between the cable core and the matrix tape.
Abstract:
A pair manager for use in securing a twin-axial cable to a printed circuit board is described. The pair manager comprises a generally block-shaped portion containing a pair of channels. The channels extend from the front face to the rear face of the block-shaped portion. An integral flange and a pair of integral fingers extend perpendicularly from the front face of the block-shaped portion. The flange extends generally from the center of the front face and the fingers extend from opposite edges of the front face. The fingers and flange function as a partial shield cavity around each pair of conductors. This design helps to maintain better impedance matching when connecting twin-axial cables to a printed circuit board.
Abstract:
Systems and methods for decreasing alien crosstalk use enhanced patch cords for introducing additional attenuation. The enhanced patch cords are preferably shielded to reduce alien crosstalk down their lengths and also attenuate signals passing therethrough to a greater extent than standard communication patch cords. The interaction of two enhanced patch cords results in two suppression steps for alien crosstalk and only one suppression step for intended signal passing through a communication cable.
