Abstract: The present invention provides a wiring degradation detector for use with telephone wire-pairs providing electric power. In one embodiment, the wiring degradation detector includes a transmission section configured to transmit load power over the telephone wire-pairs. Additionally, the wiring degradation detector also includes a test section coupled to the transmission section and configured to provide a load power test signal that determines a condition of the telephone wire-pairs. In an alternative embodiment, the wiring degradation detector further includes a degradation monitoring section coupled to the test section and configured to track values of the condition of the wiring over time.

Abstract: A system, method and article for detecting a polarity of a rotor in a motor and/or a generator. In one embodiment, a rotor polarity detection signal is applied and a response thereto is evaluated to determine whether an estimated position of the rotor is correct.

Abstract: A package assembly comprising a sealed water-impermeable bag enclosing: a spiral wound filtration element comprising a piperazine-based membrane, and an aqueous solution comprises a substantially non-oxidizable buffer having capacity to sequester at least 0.0025 moles per liter of hydrogen ions. The assembly preferably further includes a reducing agent. The assembly provides improved preservation for piperazine-based membranes and elements incorporating such membranes.

Abstract: The present invention provides a central current share coordinator for use with remotely and non-remotely controllable rectifiers coupled to an output bus. In one embodiment, the central current share coordinator includes a rectifier current resolver configured to determine an existing current share condition for the remotely and non-remotely controllable rectifiers. Additionally, the central current share coordinator also includes a load share adjuster coupled to the rectifier current resolver and configured to adjust an output current of the remotely controllable rectifiers toward a target current share distribution on the output bus.

Abstract: Power converter system topologies comprise a first DC/DC converter to pull a positive rail of a high voltage bus up, while a second DC/DC converter pushes a negative rail of the high voltage bus down. One or both the DC/DC converters may be bi-directional. Such topologies are suitable for use with separate primary power sources, and/or auxiliary power sources. Such topologies may include a DC/AC converter, which may be bi-directional. Such topologies may include one or more auxiliary DC/DC converters, which may be bi-directional. Multiple substrates, including at least one stacked above another may enhance packaging.

Abstract: A rotor assembly for use in an electric motor or generator where the mass of the rotor assembly is reduced with respect to conventional rotor assemblies. In addition, the rotor assembly is configured to be scalable to different sized electric motors. Within the rotor assembly, the rotor hub, the shaft, and the permanent magnets can independently or collectively be modified to have a reduced mass. In one aspect, a portion of the rotor hub adjacent to the shaft is configured with passages and spokes. In another aspect, an intermediate hub with lightening holes is provided between the shaft and the rotor hub. In yet another aspect, a large diameter hollow shaft replaces a portion of the rotor hub. In yet another aspect, the permanent magnets are configured to have an arc-shape, which permits the thickness of the magnets to be reduced without reducing the efficiency of the magnets.

In one embodiment, the apparatus includes: (1) a housing configured for mounting above at least some of the plurality of components in the equipment rack and (2) at least one battery pack contained within the housing and consisting of sealed unit battery cells. In another embodiment, the apparatus includes: (1) a housing configured for mounting anywhere in the equipment rack and (2) at least one battery pack contained within the housing and consisting of sealed unit battery cells that employ lithium battery technology.

Abstract: A system and method places signaling message frames in a traffic channel carrying voice frames so that the signaling message transmission does not seriously impact voice quality. This is accomplished by producing a first stream of voice encoded packets and a second stream of signaling message packets. The signaling message packets are prioritized in the second stream relative to the voice encoded packets in the first stream. An arbitration element arbitrates between the voice encoded and prioritized signaling message packets, which are multiplexed as a function of this arbitration. The multiplexed voice encoded and prioritized signaling message packets are then transmitted.

Abstract: Polyoxazolines, such as poly-2-ethyl-2-oxazoline, having a weight average molecular weight in the range of from about 1,000 to about 150,000, are effective as dispersing agents for particulate matter found in starch/clay coatings and protein/latex clay coatings for paper. Usually, 0.005 percent to about 2.0 percent polyoxazoline, based on the total weight of the binder, effectively reduces the viscosity of said paper coatings, allowing the use of higher solids in the coating composition.

Abstract: The invention provides an alternative fuel for internal combustion engines in which the exhaust heat is used to thermally dissociate water to its constituent gases hydrogen and oxygen. The hydrogen and oxygen so produced is introduced into the combustion chamber of the engine to at least partially replace the conventional fuel. In a preferred embodiment of the invention, water is dissociated into hydrogen and oxygen in a dissociation chamber in the form of a transition tube containing a spirally wound ribbon arranged to urge water in the transition tube outwardly into contact with walls of the transition tube, said walls being heated by exhaust gases of an internal combustion engine.
