Abstract:
Communications jacks include a housing having a plug aperture that is configured to receive a mating plug that is inserted along a horizontal plug axis and a vertically-oriented wiring board that is mounted substantially normal to the horizontal plug axis. First through fourth contact wires are mounted in the vertically-oriented wiring board, with the first and second contact wires forming a first differential pair of contact wires and the third and fourth contact wires forming a second differential pair of contact wires. At least a portion of the first differential pair of contact wires is positioned between the contact wires of the second differential pair of contact wires, and deflectable portions of the third and fourth contact wires include a crossover. Additionally, the fixed portions of the third and fourth contacts are spaced further apart vertically than are the fixed portions of the first and second contacts.
Abstract:
A cooling system and method for an outdoor electronics enclosure includes an air conditioner controlled to operate during off-peak hours, so as to pre-cool batteries. The cooled batteries keep the enclosure cool during peak hours so that it is not necessary to run the air conditioner when electricity prices are at their peak. A clock or light sensor determines the time of day. A controller has stored data indicating the peak hours when electricity costs more.
Abstract:
Communications patching system and methods utilizing common-mode channel communications are provided for identifying patch panel ports to which a backbone cable is connected in a communications patching system, for identifying a patch panel port to which a horizontal cable terminating at a telecommunications outlet is connected in a communications patching system, and for identifying the physical location of first and second connectors of a patch cord in a communications patching system having multiple patching zones.
Abstract:
A fuel cell cabinet is provided. The fuel cell cabinet includes a liquid cooling system for maintaining a predetermined temperature range of a first cooling liquid of the fuel cell, an air feed system for maintaining a predetermined temperature range of the temperature controlled air entering the fuel cell, a heat management system that manages and controls an internal air temperature of the housing to be one of at a predetermined temperature and within a predetermined temperature range, an air feed and exhaust system for hydrogen declassification, and a waste water management system that collects and manages the flow of the water from a fuel cell.
Abstract:
A coaxial cable may include an inner conductor, an outer conductor, and a dielectric material therebetween. The outer conductor may include a tubular bimetallic layer having a pair of opposing longitudinal edge portions at a longitudinal seam. The tubular bimetallic layer may include an inner metal layer and an outer metal layer bonded thereto. At least one of the opposing longitudinal edge portions may define at least one folded edge portion including an end portion of the outer metal layer extending beyond a corresponding end portion of the inner metal layer and being folded adjacent thereto and defining a non-joined interface therewith. The longitudinal seam may include a welded joint between at least portions of the outer metal layer.
Abstract:
Communications patching systems may include one or more patch panels, each of which has plurality of connector ports. A plurality of antennas are provided. Each antenna may be associated with a specific connector port. A radio frequency identification ("RFID") transceiver and a controller are also provided. A switching circuit is coupled between an output of the RFID transceiver and the plurality of antennas. This switching circuit includes a plurality of switches that are configured to selectively couple one of the plurality of antennas to the output of the RFID transceiver under the control of the controller.
Abstract:
A data transmission cable includes first and second longitudinally extending electrical conductors each having a longitudinally extending, substantially flat side surface. The first and second conductors are paired such that their respective flat side surfaces face one another. The cable further includes an insulation cover having a separator portion and surrounding the first and second conductors. The separator portion is interposed between and separates the respective flat side surfaces of the first and second conductors.
Abstract:
A telecommunications patching system includes a patch panel comprising a plurality of connector ports and a plurality of patch cords configured to selectively interconnect pairs of the connector ports. Each patch cord has opposite ends and a respective connector secured to each end that is configured to be removably secured within a connector port. The connectors of a respective patch cord contain the same unique identifier. A first sensor is located at each connector port and detects when a patch cord connector is inserted within, and removed from, a respective connector port. A second sensor is located at each connector port and reads the identifier of a patch cord connector inserted within a respective connector port. The first and second sensors are in communication with a controller that monitors and logs patch cord interconnections with the connector ports.
Abstract:
A 110-style patch cord includes: a plug having opposed front and rear ends and a generally horizontal support surface; a plurality of electrical contacts mounted in the plug, each contact including a generally vertically oriented blade, the blades having exposed front edges positioned above the support surface and defining a first vertical plane; and a cable with a plurality of conductors, wherein each contact is electrically connected to a respective one of the conductors, the cable extending from the front end of the plug. At least one anti-snagging gusset is mounted on the support surface in front of the first plane.
Abstract:
A coaxial cable is provided with a specially prepared precoat layer that facilitates removal of the precoat layer when the end of the cable is cored in preparation for receiving a connector. The cable includes an inner conductor; a foam polyolefin dielectric layer surrounding the inner conductor; an outer conductor surrounding said dielectric layer; and a precoat layer disposed between the inner conductor and the dielectric layer. The precoat layer forms a first bond interface with the inner conductor and a second bond interface with the dielectric layer, wherein the ratio of the axial shear adhesion force of the first ("A") bond to the axial shear adhesive force of the second ("B") bond is less than 1, and wherein the ratio of the axial shear adhesion force of the "A" bond formed by the precoat layer between the inner conductor to the dielectric layer to the rotational shear adhesion force of the bond is 5 or greater.
