  • Publication number: 20210065368
    Abstract: A system for identification of bacterial cells in free solution in a sample. A sample handler is adapted to position the sample. A light source illuminates a large volume of the sample. An imager is located to receive light scattered from the sample. A computer it is coupled to receive data transmitted from the imager. A controller is coupled to send control signals to the sample handler and the computer. The imager processes the scattered light to form images of the bacteria and transmits bacteria image information to the computer, wherein the bacteria image information includes intensity values and position data for the bacteria images from which the computer determines the presence of bacteria.

  • Patent number: 10937716
    Abstract: A layered composite configured to form an interface between a heat exchanger and an integrated circuit includes a first polymer layer, a second polymer layer, a liquid metal in direct contact with the first polymer layer, a solid solute in direct contact with the second polymer layer, and a barrier between the liquid metal and the solid solute. The liquid metal is liquid at normal temperature and pressure. The solid solute includes microparticles, nanoparticles, or both and is solid at normal temperature and pressure. The barrier prevents contact of the liquid metal and the solid solute at normal temperature and pressure, and is configured to rupture under compression of the layered composite, thereby allowing the liquid metal and the solid solute to form a mixture between the first polymer layer and the second polymer layer.

  • Patent number: 10938117
    Abstract: A cross-link satellite with spherical reflectors that can communicate in up to five substantially orthogonal directions, and thus can be included in a satellite constellation, that can be built and deployed at a lower cost than conventional satellite antennas in conventional satellite constellations. The cross-link satellite includes a communications hub in the center of a spherical balloon. The spherical balloon includes a transparent surface and three or more reflective surfaces. The reflective surfaces include a continuous reflective surface (e.g., for communicating with the ground), a first polarized reflective surface, and a second polarized reflective surface opposite the first polarized reflective surface. The first polarized reflective surface and the second polarized reflective surface are orthogonally polarized, enabling the cross-link satellite to communicate with satellites on either side of the cross-link satellite as part of a satellite constellation.

  • Patent number: 10932688
    Abstract: Systems and methods are described for enhancing sensorimotor learning using EEG decoding and closed-loop neuromodulation. A plurality of EEG electrodes and a plurality of stimulation electrodes are coupled to a learning subject. An output device of an adaptive learning system provides a sequence of instructions to the learning subject for performing a sensorimotor task in accordance with a defined learning schedule. The defined learning schedule is adjusted based on a monitored EEG signal while performing the task and, in some implementations, a neuromodulation stimulus signal is applied to the learning subject that is designed to cause the monitored EEG signal of the learning subject to approach at least one target EEG signal parameter.

  • Publication number: 20210054432
    Abstract: A method for rapid antibiotic susceptibility testing by tracking sub-micron scale motion of single bacterial cells including obtaining a biological sample from a subject including live bacteria. Different doses of antibiotic are added to a multi-well glass slide and adding portions of the biological sample to the wells. Bacterial cells are tethered onto the surface. The tethered bacterial cells are imaged and tracked. Bacterial sub-micron motion of tethered cells is measured at the different doses. A processor performs statistical analysis on a population of cells for each antibiotic dose to generate an antibiotic dose curve proportional to the motion changes, where the antibiotic dose curve plots data including a decrease in movement over time indicating a proportional effectiveness of an antibiotic applied to a well.

  • Publication number: 20210054321
    Abstract: A microfluidic device is provided that incorporates a highly organized co-culture of live cells within a microengineered platform, by which the architecture and cellular constituents of an organ or other native tissue environment may be modeled over a long period of culture for biological and/or pharmacological studies. Vertical posts (e.g., microposts) may be used to induce alignment of hydrogel-encapsulated tissues in a cell suspension region of a microfluidic device. Such a device can complement animal studies in recapitulating pathophysiological characteristics of disease. When populated with cardiac cells, such a device provides a three-dimensional (3D) biomimetic human cardiac tissue model that enables the study of pathophysiological events involved in the transition of healthy to diseased cardiac tissue, to better inform therapeutic strategies and functional outcomes in cardiac-based therapies. Other types of cells may be used in certain embodiments.

  • Publication number: 20210048206
    Abstract: An integrated method for assessing metabolic rate and maintaining indoor air quality and efficient ventilation energy use. A physical sensor assesses room occupancy. An actuated ventilation system is set to a constant CO2 level in a predetermined healthy range, where the actuated ventilation system includes a CO2 sensor. The actuated ventilation system sets a first air ventilation rate and the sensor measures a first CO2 level. The system determines whether CO2 level is in a healthy range, if not then the CO2 level is adjusted by setting a subsequent air ventilation rate. A subsequent CO2 level is measured. If the CO2 level is determined to meet a predetermined healthy range, then an assessment of change of air ventilation rate (? ACH) is determined. The determination of air change rate can be further augmented by a physical pressure based measurement. The overall metabolic rate is generated.
