Abstract: A photoplethysmograph device includes a light source for illuminating a target object. A modulator drives the light source such that the output intensity varies as a function of a modulation signal at a modulation frequency. A detector receives light from the target object and generates an electrical output as a function of the intensity of received light. A demodulator with a local oscillator receives the detector output and produces a demodulated output, insensitive to any phase difference between the modulation signal and the oscillator, indicative of blood volume as a function of time and/or blood composition. A number of demodulators may be provided to derive signals from multiple light sources of different wavelengths, or from an array of detectors. The plethysmograph may operate in a transmission mode or a reflectance mode. When in a reflectance mode, the device may use the green part of the optical spectrum and may use polarising filters.

Abstract: For imaging, an electromagnetic radiation sensor is used to produce an output when illuminated by a modulated laser light. In use, the output is determined by a laser Doppler signal illuminating the sensor. Various examples are described for achieving integration of on-chip processing onto the substrate providing the sensor. In one example, the output of the sensor is a logarithmic function of the illuminating laser Doppler signal. In another example, the output of the sensor is normalized. In another example, an amplifier arrangement is provided to amplify the output of the sensor, the amplifier gain being lower at DC than at the frequency range of the laser Doppler signal. In another example, a filter is integrated into the semiconductor device. In another example, a bandpass filter and frequency weighted filter are provided, and their outputs are processed to average values over time.

Abstract: Fetal behaviour is monitored by receiving ECG data from a set of electrodes attached to a materrial body. A waveform pre-processor identifies a succession of fetal ECG complex waveforms within the received data and a waveform processor determines differences in the processor succession of fetal ECG complex waveforms over time. An event logger determines from the determined differences a number of fetal movements during the period of time. Fetal spatial presentation and/or position within the uterus may also be determined from fetal ECG data acquired from a plurality of electrodes positioned on the maternal abdomen in a predetermined configuration. A number of fetal ECG complex waveforms are identified within the data, and each of the waveforms is compared with a set of predetermined fetal ECG complex templates ascribed to the predetermined electrode configuration to determine a template that best matches the identified fetal ECG waveforms.
