    Abstract: An apparatus and method for detecting the heart rate of a fetus. The apparatus includes three detectors detecting heart beats of the fetus, each detector including at least two electrodes detecting ECG signals, the detectors being positioned on an abdomen of a mother in use. The apparatus also includes a processor coupled to the detectors, the processor being adapted to process the ECG signals received from the detectors and determine a heart rate of the fetus. The method of determining the heart rate of the fetus includes determining a position of the fetus within a womb, placing the detectors on an abdomen of the mother, monitoring the ECG signals obtained from the detectors for a predetermined length of time, and processing the ECG signals obtained from the detectors positioned on the abdomen of the mother to determine heart beats of the mother.

    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.

    Abstract: Methods and compositions are provided for increasing the survival of nucleated mammalian cells following drying and rehydration. The methods include introducing a disaccharide such as trehalose into said cells, optionally including heat shock proteins, apoptosis inhibitors, and arbutin, drying said cells, and rehydrating them. The invention further provides nucleated mammalian cells that have increased capacity to survive, divide and, in some cases, differentiate, following drying and rehydration. The cells comprise a disaccharide and one or more of the following: a heat shock protein, an apoptosis inhibitor, and arbutin.

    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.
