Abstract: A wireless fetal and maternal monitoring system includes a fetal sensor unit adapted to receive signals indicative of a fetal heartbeat, the sensor optionally utilizing a Doppler ultrasound sensor. A short-range transmission unit sends the signals indicative of fetal heartbeat to a gateway unit, either directly or via an auxiliary communications unit, in which case the electrical coupling between the short-range transmission unit and the auxiliary communications unit is via a wired connection. The system includes a contraction actuator actuatable upon a maternal uterine contraction, which optionally is a EMG sensor. A gateway device provides for data visualization and data securitization. The gateway device provides for remote transmission of information through a data communication network. A server adapted to receive the information from the gateway device serves to store and process the data, and an interface system to permits remote patient monitoring.

Abstract: Disclosed are MEMS accelerometers and methods for fabricating same. An exemplary accelerometer comprises a substrate, and a proof mass that is a portion of the substrate and which is separated from the substrate surrounding it by a gap. An electrically-conductive anchor is coupled to the proof mass, and a plurality of electrically-conductive suspension anus that are separated from the proof mass extend from the anchor and are coupled to the substrate surrounding the proof mass. A plurality of sense and actuation electrodes are separated from the proof mass by gaps and are coupled to processing electronics. Capacitive sensing is used to derive electrical signals caused by forces exerted on the proof mass, and the electrical signals are processed by the processing electronics to produce x-, y- and z-direction acceleration data. Electrostatic actuation is used to induce movements of the mass for force balance operation, or self-test and self-calibration. The fabrication methods use deep reactive ion etch bulk micromachining and surface micromachining to form the proof mass, suspension arms and electrodes. The anchor, suspension arms and electrodes are made in the same process steps from the same electrically conductive material, which is different from the substrate material.

Abstract: A method for forming a flow sensor having self-supported heat-carrying elements is disclosed. Self-supported heat-carrying elements are capable of operating with higher thermal efficiency, enabling lower power consumption and higher sensitivity, due to a lack of heat loss into a supporting membrane. Self-supported heat-carrying elements facilitate wider operating temperature range and compatibility with harsh media.
