Abstract: A method for monitoring fetal health. The method of the present disclosure comprises transmitting (100) an ultrasound signal from an at least one transducer element in an array towards a maternal abdomen. An at least one ultrasonic echo signal corresponding to an at least one depth of the maternal abdomen is then received (102) by the at least one transducer element. The at least one Doppler signal is determined after the echo is received by the at least one transducer element is then processed (104) in an at least one channel. A multidimensional map is then generated (106) from the processed Doppler signal. A feedback (114) to reposition the at least one transducer element is then provided when the fetal heart is determined to lie outside an ultrasound beam volume.

Abstract: The invention relates to determining a fetal heart rate from an ultrasonic Doppler echo signal, which comprises at least two channels, including a first channel obtained for a first depth range and a second channel obtained for a second depth range. A first heart rate is determined from the first channel (51, 53, 55) and a second heart rate is determined from the second channel (52, 54, 56). External information on the fetal heart rate and/or the maternal heart rate, extracted from an independent source (60, 61, 62) such as an ECG, is used to select one of the first heart rate and the second heart rate as the fetal heart rate to be determined. A preferred embodiment provides for elimination of double counting heart rates by cutting out unwanted signal contributions. The disclosure further provides for an adaptive signal processing and data acquisition controlled by patient related data.

Abstract: The invention relates to determining a fetal heart rate from an ultrasonic Doppler echo signal. Rather than extracting the Doppler signal from the carrier signal using synchronous demodulation, quadrature demodulation is used, which allows to distinguish between systolic and diastolic movements. This velocity direction can be used to cut out unwanted parts of the signal (systolic or diastolic heart activity), thus eliminating double counting heart rates. In particular, a binary sign signal (15?) may be used to cut out unwanted signal episodes, resulting in a processed reference signal (10?) having only the signal parts of one heart activity. Another aspect relates to determining a first and a second heart rate from at least two channels having a different depth range, and selecting one of the first and second heart rate based on external information of the fetal or maternal heart rate.

Abstract: The invention relates to a communication device (8) for wirelessly communicating with a sensor (4). The communication device (8) comprises a receiver for receiving signals, an amplifier for amplifying the received signals, a transmitter for transmitting signals, and a controller.

The determined signal strength values can be indicative of, for instance, a saturation of the amplifier caused by a transmission operation of another, neighboring communication device such that, by considering the determined signal strength values, the transmission carried out by the communication device (8) can be synchronized with the corresponding operation of the neighboring communication device. This can lead to reduced disturbances.
