Power reduction of fetal ultrasound transducers for extended battery life

A method, comprising:

• controlling, by a fetal sensor device (FSD) comprising a processor, operations of an ultrasound transducer of the FSD in accordance with a power optimization protocol that results in minimizing power consumption by the FSD,
• wherein the ultrasound transducer is configured to measure signals representative of one or more fetal parameters of a fetus using doppler based ultrasound technology in association with positioning of the FSD on an external body of a mother of the fetus, wherein the FSD operates in an active mode that comprises alternating between transmit periods wherein the ultrasound transducer transmits ultrasound signals, and receive periods wherein the ultrasound transducer measures reflected signals of the ultrasound signals that are received by the ultrasound transducer during the receive periods, and
• wherein the controlling comprises controlling, while maintaining operation of the ultrasound transducer in the active mode, at least one of a transmission power of the ultrasound signals or a duration of the transmit periods in accordance with the power optimization protocol.

A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor of a fetal sensor device (FSD), facilitate performance of operations, comprising:

• controlling operations of the FSD in accordance with a power optimization protocol that results in minimizing power consumption by the FSD,
• wherein the FSD comprises an ultrasound transducer configured to measure signals representative of one or more fetal parameters of a fetus using doppler based ultrasound technology in association with positioning of the FSD on an external body of a mother of the fetus, wherein the FSD operates in an active mode that comprises alternating between transmit periods wherein the ultrasound transducer transmits ultrasound signals, and receive periods wherein the ultrasound transducer measures reflected signals of the ultrasound signals that are received by the ultrasound transducer during the receive periods, and
• wherein the controlling comprises controlling, while maintaining operation of the ultrasound transducer in the active mode, at least one of a transmission power of the ultrasound signals or a duration of the transmit periods in accordance with the power optimization protocol.
