  • Patent number: 6743187
    Abstract: A control system is adapted for use In association with a therapeutic motion and splinting device. The therapeutic device has at least one component that is monitored. The system comprises the steps of defining the range of motion, defining the maximum reverse on load, monitoring the reverse on load and moving the device through its range of motion. A first and second maximum limit of range of motion in a first and second direction are respectively defined. A maximum reverse on load is defined and is monitored whereby the deformation of the at least one component is monitored and the load created is interpreted. The device is cycled between a first and second position defined by one of the first maximum limit and the maximum reverse on load and one of the second maximum limit and the maximum reverse on load respectively.

  • Patent number: 4839601
    Abstract: An electrical detection system for locating a position of interest in a medium which is electrically conductive includes a signal generator, a source, a sink and at least two probes. The probes are disposed in the medium equidistantly spaced from either the sink or the source. A signal generated by the generator flow from the sink and to the source and will also flow to the probes. The probes are connected to input terminals of a comparator to thereby compare the signal strengths at the probes. The probes are movable to different positions in the medium to determine a cross-over position such that, at the cross-over position, the perpendicular bi-sector of the line joining the probes indicates the point of interest by pointing in the general direction thereof.
