  • Patent number: 7675714
    Abstract: The present invention is a system for stiffening a voice coil of a magnetic disk drive. One embodiment of the present invention are stressed skins that interconnect with an upper portion and a lower portion of the voice coil such that they are flush with the upper and lower surfaces of the voice coil. The stressed skins are adhered or otherwise interconnected to the voice coil thus allowing for bending, twisting, torsional, and various other loads that generate vibrations that affect the head of an actuator assembly to be dampened. One embodiment of the present invention includes two stressed skins interconnected to a voice coil constructed of carbon composite wherein the space therebetween is filled with a foam to provide additional stiffness and damping.

  • Patent number: 5456037
    Abstract: A securable fish net apparatus comprising a fishing net further comprising a racket having a generally annular head and a handle extended therefrom; and a mesh material coupled about the head of the racket to define a pocket for holding fish therein; a strap having a securement mechanism on one end and securable mechanism on the other end with the securable mechanism adapted to be coupled with the securement mechanism in a closed loop configuration about the wrist of a fisherman; a first coupling mechanism having one orientation for coupling the racket to the strap and another orientation for decoupling the racket from the strap; and a second coupling mechanism coupled to the racket and adapted to secure the handle to an arm of a fisherman; whereby when the strap is secured about the wrist of a fisherman, and when the racket is coupled to the strap with the first coupling mechanism, and when the second coupling mechanism is secured about his arm, his adjoining hand is free to control a hooked and netted fish.
