  • Patent number: 6279511
    Abstract: A method and system for infusing and monitoring a tethered laboratory animal includes a platform suitable for carrying the laboratory animal. A tether assembly includes a flexible conduit for connecting to the animal and a tether for tethering the animal. A torque sensor detects a motion of the animal and drives the tether assembly in response to the detected motion of the animal, and thereby reduces the torque on the animal. The platform is driven in a direction opposite to the tether assembly so that it appears to be stationary when the tether assembly is driven in response to a detected motion of the animal.

  • Patent number: 5577891
    Abstract: A pump and a method for pumping liquid or fluid through a pair of resilient tubes includes a pushing mechanism which partially compresses the tubes in a balanced, alternating, rocking manner. The resilient tubes are held in a parallel relationship. The pushing mechanism alternately compresses the tubes. As one of the two parallel tubes is compressed, fluid is pumped out of the tube and at the same time fluid is drawn into the second tube as the latter tube resumes its original shape. The resilience of both tubes also is used to assist the pumping action in a balanced fashion, thereby providing a pump that has low power consumption and is lightweight.
