  • Patent number: 6091238
    Abstract: The present invention incorporates a system for varying the output signal and regulating the power consumed by an electrical device. It achieves its purpose by moving a magnet relative to a Hall effect sensor which is responsive to an intersecting magnetic field. The Hall effect sensor creates an electrical output signal which determines the input signal of an output element of the device. The electrical Hall effect sensor signal thereby controls the output signal emitted by the electrical output element. The magnet is moved using a movable element. Since the location and movement of the magnet regulates the Hall effect sensor output signal, the output signal of the electrical device as well as its rate of change are regulated using the movable element. In order to conserve power the Hall effect sensor element is usually not energized when the device is in the "off" mode.

  • Patent number: 6059825
    Abstract: A removable or absorbable vena cava filter is introducible through a relatively small bore catheter. These filters formed of a single high-memory wire. The wire has a coiled cylindrical portion and a coiled conical portion. The wire assumes a straight configuration when in a catheter. The coils of the cylindrical portion have a sufficiently large diameter contact the walls of the inferior vena cava with sufficient force to hold the coils in place against the inferior vena cava. The cylindrical portions of the wire has an anchor attached to it in a non-absorbable embodiment of the invention. The conical portion of the wire has a segment which aids in the removing of the filter from the vena cava.

  • Patent number: 6057920
    Abstract: In coherence tomography, an interferometric measurement light beam scans the measurement object and is focused for improving the transverse resolution. In order to achieve a high transverse resolution over the entire object depth, the focal displacement and the change in path length in the measurement light beam for maintaining the coherence of the focus is achieved by one and the same moving optical element in the measurement light beam. The present invention achieves this by a particularly simple and easily adjustable arrangement which is characterized by especially low light loss in the measurement beam path.
