In an embodiment, a UPS of the present invention can individually regulate the charging of its capacitive elements to avoid overcharging and/or achieve a more efficient charge state. | 01-16-2014 |
20140027036 | Methods of Manufacturing a Communication Cable - Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape. | 01-30-2014 |
20140080354 | Intelligent Patching System - 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. The system is also capable of monitoring patch cord connections to detect insertions or removals of patch cords or plugs. In addition, the system can map embodiments of patch fields. | 03-20-2014 |
20140091138 | RFID System - 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 via a flexible mounting system, and RFID antennas (and corresponding 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. | 04-03-2014 |
20140187077 | COMMUNICATION PLUG WITH IMPROVED CROSSTALK - A communication plug having a plug body and a plurality of contact pairs at least partially within the plug body, the contact pairs including an inherent asymmetric coupling between individual contacts of one of the contact pairs and other individual contacts of another of the contact pairs. Second asymmetric coupling elements are connected between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs. The second asymmetric coupling elements, when combined with the inherent asymmetric coupling, provide a balanced symmetric coupling between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs. | 07-03-2014 |
20140190734 | SHIELDED WIREWAY SYSTEMS - Certain embodiments of the present invention provide a duct for a shielded wireway system. The duct includes a bottom wall, two sidewalls extending from the bottom wall, and a plurality of fingers extending from each of the sidewalls. Adjacent fingers are connected by at least one bridging component. The bottom wall, the sidewalls, and a portion of the fingers, including the bridging component, are shielded. | 07-10-2014 |
20140247537 | Medium Voltage Power Distribution in Data Centers - A medium voltage power distribution system containing a power distribution cabinet with a first and second power supply is described. The cabinets contain one or more power distribution unit static transfer switch units. These units are connected to both the first and second power supplies of the cabinets. The power distribution unit static transfer switch units each have one or more power distribution blades removably contained within. The power distribution blades have first and second power contacts that respectively electrically engage first and second power contacts on the power distribution unit static transfer switch units wherein the first and second power contacts of the power distribution static transfer switch unit are respectively connected to the first and second power supplies of the power distribution cabinet. | 09-04-2014 |
20140256182 | COMPENSATION NETWORKS AND COMMUNICATION CONNECTORS USING SAID COMPENSATION NETWORKS - 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. | 09-11-2014 |
20140374479 | RFID System - 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 corresponding readers) are strategically located in close proximity to read the tags.
