  • Patent number: 11501902
    Abstract: A system comprising a solenoid electromagnet for generating a magnetic field and a driver circuit coupled to the solenoid electromagnet for modulating the magnetic field generated by the solenoid electromagnet. The magnetic field generated by the solenoid electromagnet of the present invention exhibits improved control over the direction and projection of the generated magnetic field. The generated magnetic field has the ability to detach permanent magnets from metal plates, cause motion of permanent magnets and soft magnetic materials as well as create separation between two magnetically bound permanent magnets.

  • Patent number: 9991545
    Abstract: A metal air flow battery includes an electrochemical reaction unit and an oxygen exchange unit. The electrochemical reaction unit includes an anode electrode, a cathode electrode, and an ionic conductive membrane between the anode and the cathode, an anode electrolyte, and a cathode electrolyte. The oxygen exchange unit contacts the cathode electrolyte with oxygen separate from the electrochemical reaction unit. At least one pump is provided for pumping cathode electrolyte between the electrochemical reaction unit and the oxygen exchange unit. A method for producing an electrical current is also disclosed.

  • Patent number: 6904836
    Abstract: A screw holding screwdriver adapter includes first and second elongated mating elements held together by a mounting member. The mounting member engages the elongated mating elements in an opposed relationship so as to define a screwdriver shank engaging portion between the first ends with the second ends cooperating to define a screw engaging portion. The first and second elongated mating elements and the mounting member further define a screwdriver blade and shank receiving opening therein. The screw engaging portion is formed to fit easily in the slot of a screw and to expand, when the blade of a screwdriver is inserted between the second ends, to grip the screw until the screw can be partially engaged in a desired opening. The adapter can then be slid up the screwdriver shank or removed from the screwdriver and the screw is mounted in a normal fashion.
