Abstract: An active filter system for filtering power on a power system may include a converter, an energy storage device, and control circuitry. The converter may be configured to be electrically coupled to a power source at a converter input and an active filter system bus at a converter output. The converter may be configured to deliver power to the active filter system bus that serves a dynamic load. The energy storage device may be electrically coupled to the active filter system bus and configured to filter the power via charge and discharge of an energy storage device. The control circuitry may be configured to control the converter to condition power drawn from the power source to create a filtered load based on programmable active filter controls. The programmable active filter controls may be based on a measurement of a load current being supplied to the dynamic load and a state of charge of the energy storage device.

Abstract: The present disclosure is associated with monitoring health of a patient. An example photoacoustic monitoring device includes a light-guiding component to guide light energy toward tissue to cause the light energy to be absorbed by the tissue; an ultrasound transmission component to transmit acoustic energy toward the tissue to cause a biological response from the tissue; and a sensing component to perform one or more of ultrasound or photoacoustic imaging to sense the biological response from the tissue and permit a status of the tissue to be determined. In some implementations, the biological response is sensed based on the light energy absorbed by the tissue during the biological response caused by the acoustic energy transmitted toward the tissue.

Abstract: The present invention provides a method and device for non-invasive anatomical and systemic cooling, fluid removal and/or energy removal. The method and device provide for removal of fluid and cooling of various bodily fluid-containing spaces or surfaces, such as mucus-containing spaces or surfaces via delivery of a dry fluid not including a coolant into or upon the mucus-containing space or surface. Exposure of such mucus to the dry fluid results in evaporation of body fluid, removal of energy, cooling of the anatomical feature, and systemic cooling. In this fashion, therapeutic hypothermia may be achieved to provide for neuroprotection of various organs after ischemic insult, such the brain after cardiac arrest. Similarly, excess fluid removal may be achieved for treatment of cardiogenic shock or other conditions that cause significant fluid build-up, especially in cases of compromised renal function.
