  • Patent number: 8014554
    Abstract: An automatic tilt speaker has a first subassembly of a speaker unit enclosing an ordinary speaker element. The speaker unit includes a cone-shaped housing having an inner cavity for holding the speaker with its frame or basket fitted snugly in an annular frame. The housing of the speaker unit is pivotally connected to the frame by a pivot arm. The speaker housing has an arcuate exterior wall extending in a radius centered about the pivot connection of the frame. Centrally of the arcuate wall, there is a gear arch, which comprises a vertical column of horizontally elongated teeth extending substantially coplanar with the arcuate wall. On the annular frame at the diametrically opposite side of the pivot connection a tilting system is operatively connected with the teeth. The tilting system includes a motor with a reduction gearbox for driving a worm gear, which in turn drives the gear arch. The annular frame also supports a relay-based motor control board for controlling the polarity and power to the motor.

  • Patent number: 7959541
    Abstract: An ultra light but resistive ball device for exercise is provided comprising: a flexible sheet with least one preliminary broken section of collapse for allowing contraction of the sheet under bias about at least one flex point in response to an exertion of hand grip. The sheet has two free ends extending substantially half the circumference of the ball and partially folded back on the sheet. Two lateral apertures are located at opposite ends of the free ends to permit an uninterrupted collapse of the sheet. A sheath envelopes the sheet to provide a slip resistant exterior surface for grasping the ball.

  • Patent number: 7935035
    Abstract: A gyroscopic exercise device has a pair of handles attached to a housing. A user holds and rotates the handles along cone-like paths causing precession of a rotor, which is rotating about its spin axis, to provide resistance to the user. The device has an axle disc that holds ends of an axle of the rotor. The periphery of the axle disc and the ends of the rotor axle are within a circular race in the housing. A retracting spool allows pull starting. An optional motor attached to the axle disc has a wheel for rotating the rotor about a spin axis by a temporary supply of power from included batteries in one of the handles. An optional abdominal rolling ring provides abdominal exercise.
