    摘要： A continuous, non-invasive fetal heart rate measurement is produced using an ultrasound probe positioned on the abdomen of the mother. The ultrasound probe includes a plurality of ultrasound transducers that are positioned within a housing having a transmission surface. The transmission surface is configured to defocus the individual ultrasound beams created by the plurality of ultrasound transducers. The transmission surface defocuses the ultrasound beam and creates a wider area of coverage for the ultrasound probe. The controller contained within the heart rate monitor selectively activates different combinations of the plurality of ultrasound transducers to reduce the signal-to-noise ratio while allowing the ultrasound probe to locate the fetal heart beat and subsequently increase the signal-to-noise ratio during continuous heart rate monitoring.

    摘要： A curved sensor device, such as an ultrasonic transducer array, is fabricated from a flat micromachined sensor (such as cMUT or pMUT) array constructed using micromachined electromechanical systems (MEMS) techniques. The device comprises: a support structure comprising a spine having a profile that is generally curved and a multiplicity of teeth extending from one side of the curved spine; and a multiplicity of sensors built on the support structure. The spine can be bent forward or backward and attached to a curved front face of a support member, thereby causing the sensors to adopt a curved array.
