  • System for detecting a location of a subsurface channel
    Patent number: 9588247
    Abstract: A system for detecting a location of a subsurface channel may include a portable frame and a plurality of magnetic coils supported by the frame. The magnetic coils may be spaced apart from one another and ends of each of the magnetic coil are unobstructed by other of the magnetic coils.

  • Subsurface hydrogeologic system modeling
    Patent number: 8688423
    Abstract: A method of modeling a subsurface hydrogeologic system within a study area can include applying an electric current directly to the subsurface hydrogeologic system and monitoring a magnetic field generated by the electric current in the subsurface hydrogeologic system. An electric current distribution can be identified within the study area by an inversion process based on the magnetic field. A model of the electric current distribution can be created.

  • Atraumatic anchoring and disengagement mechanism for permanent implant device
    Patent number: 7799049
    Abstract: A recoverable thrombosis filter that may be recoverable by a single recovery procedure. It can include a plurality of thrombosis filtering elements that are shaped in a predetermined manner and which are joined at one end and are deployed about a longitudinal axis to form a generally conical structure. The filtering elements can include shaped ends for engaging an inner lumen wall.

  • Hydraulic systems
    Patent number: 5584224
    Abstract: An hydraulic lift system has an actuator connected to an hydraulic circuit, having a pump, via a supply line. A balanced seated valve is connected between the supply line and a reservoir, the valve being controlled by a solenoid and an electric drive unit. The drive unit supplies a gradually increasing or decreasing voltage to the solenoid to open or close the valve gradually. The valve has a valve member that is displaceable along its length and has a valve head of frusto-conical shape. A passage along the valve member balances fluid pressure across the valve member. The solenoid has an armature with a pole face that can be displaced towards a fixed pole face to unseat the valve member. The pole faces have complementary frusto-conical surfaces and there is a non-magnetic washer between them.
