  • Patent number: 10351931
    Abstract: Extraction of rare earths from end-of-use machinery having rare earth magnets provides a closed-loop process towards recycling rare earths from commingled devices having embedded magnets such as motors, generators and disk drives. A low temperature process selectively leaches the magnet material from mixed scrap containing shredded fragments of the machinery which includes other metals such as steel and copper. Filtration separates the other metals from the leached, dissolved magnet material, which is precipitated by oxalic acid to form oxalates in powder form, suitable for use in production of new rare earth magnetic material. Leaching acid, such as HCl (hydrochloric acid), is recoverable via pyrohydrolysis, and redirected back to the leaching step for completing the closed-loop aspect.

  • Patent number: 10285601
    Abstract: A real-time arrhythmia discrimination method is used in smartphones, which can discriminate between NSR, AF, PACs and PVCs using pulsatile time series collected from a smartphone's camera. To increase the sensitivity of AF detection and add the new capabilities of PVC and PAC identification, the arrhythmia discrimination method of these teachings combines Root Mean Square of Successive RR Differences (RMSSD), Shannon Entropy (ShE) and turning point ratio (TPR), with the Poincare plot, and utilizes the features of pulse rise/fall time and amplitude for arrhythmia discrimination.

  • Patent number: 10132527
    Abstract: An electrohydrodynamic (EHD) pump increases refrigerant flow rate and the resulting pressure in a vapor compression based cooling system for permitting reduced compressor sizes and power demands. The EHD pump disposes electrodes in a liquid path of the refrigerant flow, and increases fluid flow and resulting pressure by an induced liquid flow between a pair of asymmetric electrodes. Voltage applied to these electrodes results in a conduction pumping mechanism associated with heterocharge layers in the vicinity of the electrodes based on disassociation of a neutral electrolyte species in the refrigerant fluid and recombination of the generated ions. The induced flow draws the liquid due to a net fluid flow toward one of the electrodes based on the asymmetry of the electrode pair. Electrodes are disposed on an inner surface of a refrigerant vessel, in communication with an annular liquid film that forms around the inner circumference in two-phase fluid systems.

  • Patent number: 10119758
    Abstract: Drying a planar substrate such as paper sheet goods for packing materials includes layering a phase change material (PCM) on a substrate, in which the substrate has a moisture content and adapted for moisture removal to form a planar medium. A drying process disposes the substrate adjacent to a plurality of rollers and heat the layered substrate to a predetermined temperature based on a specific heat of the PCM. The rollers advance the layered substrate in series through pocket ventilation regions between the heat transfer elements, such that the pocket ventilation regions permit drying of the substrate enhanced by the specific heat of the temperature sensitive material. Upon drying, the layered substrate forms the planar medium suitable for use as a packing medium or other suitable application. The pocket ventilation regions are based on the PCM to facilitate drying and eradication of moisture from the paper planar substrate.
