Abstract: A modular edge power system is provided. The modular edge power system includes a housing having a rack adapted to mount compute devices and a direct current power bus within the housing. Multiple power distribution units are adapted to be removably coupled to the direct current power bus at a position within the housing and outside of the rack. Each power distribution unit is configured to distribute electrical power received from the direct current power bus to one or more compute devices mounted in the rack. Each power distribution unit may convert the electrical power from a first power level to a second power level.

Abstract: A method for inferring a relationship between a first user and an area is disclosed, where the user is associated with one or more user devices. The method comprises retrieving event records having user device information corresponding to the user devices, and inferring, based on the event records, a relationship between the user and the area. A method for determining the presence of users at a location of a plurality of locations organised in a hierarchical structure is also disclosed. The method comprises receiving an indication of a location selected from the hierarchical structure, determining nodes associated with the selected location, retrieving event records from each node, and determining, based on the retrieved records, a number of users located at the selected location.

Abstract: One aspect provides a pluggable power management module, comprising a module housing having input and output pluggable connectors extending therefrom configured to be couplable to a corresponding input and output terminals of a conventional, generic distribution panel, a controller interface located on or within the module housing and couplable to a controller, and a sensor located within the module housing and coupled to the controller interface and configured to produce a signal to the controller, that determines that a minimum or maximum threshold voltage or current of a source/load coupled to the pluggable power management module has been reached based on the signal.

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: 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.

Abstract: A method for detecting internal larval infestation in granular material comprising the steps of: creating an image of grain kernels in the near Infra-Red region; applying a mask to the image to exclude interference on the outer reaches of the kernel; forming a model kernel by applying a medium filter and slightly enlarging the resulting approximate model; comparing the masked image with a model kernel to obtain a difference image; and applying a threshold to difference image to determine larval infestation.

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: Apparatus for magnetically treating seeds comprises a magnet for producing a unipolar magnetic field, an enclosed generally cylindrical housing having a closable access opening therein in which said seeds are placed for treatment, drive means associated with the housing for rotating said housing and imparting rolling and tumbling motion to the seeds within the housing, the housing being disposed with respect to the magnet such that the seeds move through the magnetic field as they roll and tumble. By magnetically treating the seeds in a unipolar magnetic field while rolling and tumbling the seeds, the characteristics of plants grown therefrom are favorably altered.
