  • Patent number: 6263230
    Abstract: A device to detect the location of a plurality of magnets uses a plurality of magnetic sensors, having sensor elements arranged in a known fashion. Each sensor element senses the magnetic field strength generated by each of the plurality of magnets and provides data indicative of the direction of the magnets in a three-dimensional space. The device uses fundamental equations for electricity and magnetism that relate the measured magnetic field strength to the location and strength of the magnetic dipole for each of the plurality of magnets. The device may use an iterative process to determine the actual location and orientation of each magnet. An initial estimation of the location and orientation of each magnet results in the generation of predicted magnetic field values. The predicted magnetic field values are compared with the actual measured values provided by the magnetic sensors.

  • Patent number: 4890624
    Abstract: A fetal heart rate counting system which includes a transducer element for transmitting an ultrasound signal into the fetal heart while the fetus is in utero and for receiving a returning Doppler signal frequency shifted by action of the fetal heart. The returning Doppler signal is processed to produce a forward heart movement Doppler signal, a reverse heart movement Doppler signal and the complete Doppler signal, from each of which fetal heart rate data is obtained. A composite fetal heart rate data is then produced from the three processed Doppler signal which is more accurate and complete than the data from any one signal individually.
