  • Method and apparatus using threshold techniques for generating an alarm in a bio-sensor
    Patent number: 5469144
    Abstract: A method for selecting and implementing waveform processing techniques for a Bio-Sensor.RTM.. The ventilatory cycles of a fish are used to determine when an alarm state is present. Threshold techniques used in the waveform processing include a dynamic threshold method and a static threshold method.

  • Bio-amplifier for sensing the bio-electric field of fish
    Patent number: 5307052
    Abstract: The present invention provides a bio-amplifier in a water quality system. The bio-amplifier detects and amplifies a ventilatory behavior of a fish. The ventilatory behavior is converted to a signal. The signal is an instantaneous determination of the quality of water being tested.

  • Monitoring tank modules and array for use with biological sensors
    Patent number: 5140855
    Abstract: A monitoring tank for fish used as biological sensors wherein water being monitored for quality and toxins continuously flows. Extraneous noise is mostly eliminated by suitable grounding. Aluminum racks with slide guides support the multiple monitorin tanks for each access to the monitoring tanks. The water is discharged from the monitoring tanks into drain trays located under the aluminum racks.
