Abstract: Methods and systems are provided for a microfluidic cartridge including a high performance actuator useful for analyte detection, labeling and analysis. Microfluidic processing systems are to carry out chemical or biochemical reactions, or sequences of reactions, with small volumes (typically between 1 microliter and 10 milliliters) of reactants and products. A microfluidic processing system can comprise a network of tubes interfaced with discrete components such as valves and sensors, or an integrated device made of plastic, glass, metal, or other materials, or a combination of materials, with components such as valves and sensors built into the device and connected by flow passageways formed in the material.

Abstract: A microfluidic device includes a three-dimensional slat structure having a plurality of interstices configured to generate a high power, high flow rate of fluids by electroosmotic flow. The microfluidic device includes a housing for holding and moving fluids through the slat structure, and a plurality of electrodes that generate an electric field within the plurality of interstices.

Abstract: A radar-based physiological motion sensor is disclosed. Doppler-shifted signals can be extracted from the signals received by the sensor. The Doppler-shifted signals can be digitized and processed subsequently to extract information related to the cardiopulmonary motion in one or more subjects. The information can include respiratory rates, heart rates, waveforms due to respiratory and cardiac activity, direction of arrival, abnormal or paradoxical breathing, etc. In various embodiments, the extracted information can be displayed on a display.

Abstract: Aspects of the of the disclosure relate to a non-contact physiological motion sensor and a monitor device that can incorporate use of the Doppler effect. A continuous wave of electromagnetic radiation can be transmitted toward one or more subjects and the Doppler-shifted received signals can be digitized and/or processed subsequently to extract information related to the cardiopulmonary motion in the one or more subjects. The extracted information can be used, for example, to determine apneic events and/or to provide apnea therapy to subjects when used in conjunction with an apnea therapy device. In addition, methods of use are disclosed for sway cancellation, realization of cessation of breath, integration with multi-parameter patient monitoring systems, providing positive providing patient identification, or any combination thereof.
