    摘要: A sensor chip (1030) for gas has cells (200) for emitting and receiving ultrasound and is configured for a sufficiently large frequency range and for measuring concentration of at least one of the gas components based on at least two responses within the range. The frequency range can be achieved by varying the size of cell membranes (230), varying bias voltages, and/or varying air pressure for an array (205) of cMUTs or MEMS microphones. The sensor chip can be applied in, for example, capnography. A measurement air chamber (515) is implemented in the respiratory pathway (400), and it and/or the pathway may be designed to reduce turbulence in the exhaled breath (120) subject to ultrasound interrogation. The chip (1030) can be implemented as self-contained in the monitoring of parameters, obviating the need for off-chip sensors.

    摘要: Systems and methods for contact-less, non-invasive determination of peripheral temperature of a subject use a thermal exchanger to locally modulate the temperature of a structure in engagement with the subject, such as a subject support structure that supports the subject or an item worn by the subject. A thermal sensor can be used to monitor a thermal response of the subject and to determine the peripheral temperature. Additionally or alternatively, the core body temperature may be determined.

    摘要: The invention provides a synthetic jet eductor pump that includes a synthetic jet actuator coupled to a fluid conduit. The synthetic jet actuator may include a vibratable membrane, an actuating portion that vibrates the vibratable membrane, a pump chamber coupled to the vibratable membrane, and a pump conduit in fluid communication with the pump chamber such that vibration of the membrane draws fluid into and ejects fluid from the pump conduit to create a net momentum of fluid in a predetermined direction. The fluid conduit may include a jet receiving portion between intake and ejection portions thereof, wherein the jet receiving portion is in fluid communication with the pump conduit. The net momentum of fluid created by the synthetic jet actuator may be communicated to the fluid conduit at the jet receiving portion to create fluid flow in the fluid conduit from the intake portion to the ejection portion.
