Abstract: A heat pump system is provided that uses multiple stages of MCMs with different Curie temperature ranges. An adjustable fluid flow path is used whereby the number of stages through which a heat transfer fluid passes can be varied depending upon e.g., the amount of heating or cooling desired. In certain embodiments, a magnetic field used to activate the MCMs can be manipulated so that the number of stages of MCMs that are activated also be adjusted. These and other features can improve the operating efficiency of the heat pump.

The collimator can be sized and shaped to collimate an X-ray beam from the X-ray source that exposes a receptor region on the detector. The collimator can allow the X-ray image received by the X-ray detector to have any suitable shape that allows a relatively large view of the image to be displayed and rotated on the display device without changing the shape or size of the image as it rotated. In some instances, the collimator provides the image with superellipse shapes or cornerless shapes having four substantially straight edges with a 90 degree corner missing between at least two edges that run substantially perpendicular to each other. Other embodiments are described.

Patent number: 8942353
Abstract: A system and method for x-ray tube components is disclosed. The method of fabricating an x-ray tube component includes providing a powder into an electrically conductive die constructed to have a cavity shaped as the x-ray tube component being fabricated and simultaneously applying a mechanical pressure and an electric field to the die so as to cause sintering of the powder and thereby fabricate the x-ray tube component, wherein the electric field applied to the die directly passes through the die to the powder, so as to generate heat internally within the powder responsive to the applied electric field.

Patent number: 8939294
Abstract: A separation matrix comprises a porous surface layer; and a bulk porous support, wherein both the porous surface layer and the bulk porous support comprising a block copolymer. The block copolymer comprises A-B or A-B-A repeating units, wherein A and B at each occurrence are two different blocks of oligomer, or polymer. A structural unit of block A is derived from one or more atom transfer radical polymerization (ATRP)-active monomer or oligomer and a structural unit of block B is derived from a thermoplastic ATRP-active macro initiator. A poly dispersity index of the block copolymer is at least about 2.

Abstract: A system includes a first network member that includes a first channel and a second channel. The first channel is configured as a charging channel and is configured to at least one of wirelessly receive or transmit power. The first channel is also configured to transmit network pairing information for at least one of pairing or un-pairing the first network member and a second network member. The network pairing information is transmitted over the first channel at a first frequency. The second channel is configured as an operational channel, and is configured to communicate operational information between the first and second network members when the first and second network members are paired. The operational information is transmitted over the second channel at a second frequency that is different than the first frequency.

Abstract: A system for dynamically controlling content displayed on a condition monitoring system may include a processor that may receive one or more datasets associated with one or more components in an industrial environment. The system may also include a graphical user interface (GUI) that may display visualizations representing the components in a first portion of the GUI. The GUI may then receive a first selection of the visualizations and display data processing outputs associated with the first selection in a second portion of the GUI. There, the data processing outputs may be determined based on a first dataset that corresponds to a first component associated with the first selection. The GUI may then receive a second selection of the visualizations and may dynamically update the data processing outputs based on a second dataset that corresponds to a second component.
