Abstract: A percussive massage device includes an enclosure having a cylindrical bore that extends along a longitudinal axis. A motor has a rotatable shaft that rotates about a central axis perpendicular to the longitudinal axis. A crank coupled to the shaft includes a pivot, which is offset from the central axis of the shaft. A reciprocation linkage has a first end coupled to the pivot of the crank. A piston has a first end coupled to a second end of the reciprocation linkage. The piston is constrained to move within a cylinder along the longitudinal axis of the cylindrical bore. An applicator head has a first end coupled to a second end of the piston and has a second end exposed outside the cylindrical bore for application to a person receiving treatment. A motor controller measures current applied to the motor and displays a pressure indicator responsive to the measured current.

Abstract: A fitness ball has first and second hemispheres, which are connectable to form a complete sphere. The first hemisphere supports a motor having a pair of rotatable eccentric masses at opposite ends of a common drive shaft. The second hemisphere supports a rechargeable battery pack, electronic circuitry and indicators LEDs. The electronic circuit controls the charging of the battery pack and also selectively provides electrical power from the battery pack to the motor to control the rotational speed of the motor to rotate the eccentric masses. The rotating eccentric masses cause vibrations that are communicated from the motor to the two hemispheres. The vibration frequency is controlled by the rotational speed of the motor. The hemispheres have outer covers having a configuration that is easy to grip such that the vibrations are communicated to a users hands. The ball is substantially balanced about an equatorial plane.

Abstract: A portable vibrating roller includes an outer roller structure having a plurality of grooves and ribs. A hollow cylindrical bore extends longitudinally through the shell. A vibration system having a first end cap and a second end cap fits within the bore. A battery positioned within the shell near one end cap provides electrical power to a motor positioned within the shell near the other end cap to cause the motor to rotate an output shaft at a plurality of angular velocities to rotate an eccentric mass located approximately midway between the two end caps. The rotating eccentric mass causes vibration. A motor control circuit receives input power from a battery and selectively provides output power to the motor in response to the operation of a switch on the first end cap. The output power is varied to control the angular velocity of the output shaft of the motor and to thereby control a frequency of vibration caused by the eccentric mass.

Abstract: A system simultaneously applies compression and cooling to a body part. An ice bag has a removable cap for inserting ice and removing water. An air release valve in the cap allows release of air from the ice bag without removing or loosening the cap. A compression wrap is a unitary sheet of elastic material having a central body with straps extending therefrom. A hole in the central body receives the neck of the ice bag, which is positioned over the body part. The unitary body and straps of the sheet apply pressure via the ice bag. Air released into the ice bag from melting ice is removed via the air release valve without disturbing the compression wrap or the cap. The compression wrap contracts to compensate for the volume of the released air, thus maintaining continuous pressure on and thermal contact with the body part.
