  • Publication number: 20220007624
    Abstract: The present invention relates to a fishing lure system for increasing the chances of catching fish. The fishing lure includes a number of fish molds or heads attached to a wire arm, with several of the fish molds having an LED feature and a spinner blade attached thereto. The presence of the LED fish molds and spinner blades in close proximity to one another when travelling through the water provide an illusion of a school of bait fish that will attract, and enable the angler to catch, a larger number of targeted fish and with greater frequency.

  • Patent number: 4346416
    Abstract: A rotary actuator assembly for positioning read/write heads in disk drive mass storage systems. The actuator assembly includes an actuator motor and one or more actuator arms secured thereto. The motor provides rotary motion of the arms, to move the heads. The stator magnet of the motor is an electromagnet wound on an arcuate core; a pair of elongate permanent magnets are attached to the rotor member, for coaction with the stator magnet. The rotor member has a U-shaped cross sectional area in a plane perpendicular to its axis of rotation; the permanent magnets are fixed to the outside, bottom corners of the U and the actuator arms are mounted across the open end of the U. The rotor is of a very small radius, to minimize inertia. The permanent magnets have a flat face facing the stator, with a channel running longitudinally down the middle, to minimize flux density variations in the permanent magnet-coil gap. The rotor balances the arm relative to the rotor's axis.
