Abstract: An apparatus and system for manipulating soft tissue may include a support member and a raised member. The support member includes a support surface disposed between a first end of the support member and a second end of the support member. The support member is elongated in a lengthwise direction between the first end of the support member and the second end of the support member. The raised member includes an outer surf ace disposed opposite an inner surface. The inner surf ace is supportable by the support surface of the support member. The outer surf ace of the raised member is configured to rotate along at least a portion of a user's body in response to movement of the raised member along the user's body. The raised member is repositionable along the support surf ace of the support member in the lengthwise direction.

Abstract: An apparatus and system are disclosed for manipulating soft tissue. The apparatus includes a support member, a plurality of substantially circular voids disposed through the support member, and a plurality of spherical members. Each substantially circular void is positioned in alignment with a substantially hemispherical recess having a concave surface defining a spherical member receiving space. Each spherical member is positioned within a spherical member receiving space and is rotatable within one of the spherical member receiving spaces about an infinite number of axes of rotation. Each concave surface of the substantially hemispherical recess is made from a first material and an outer surface of each spherical member is made from a second material. The first material and the second material are selected such that a static coefficient of friction between the first material and second material facilitates rotation of the spherical members within the spherical member receiving spaces.

Abstract: The present disclosure relates to a method for driving a ski course gate into a snow covered surface. The method includes the step of providing a portable driver having a housing, a drive member rotatedly connected to the housing, a gate engaging structure connected to the drive member, a rotational power source, and a rotational transference assembly mounted within the housing for transferring a rotational input from the rotational power source to the drive member. The method also includes the steps of inserting a pole portion of the ski course gate within a longitudinal channel of the drive member and sliding the pole portion longitudinally through the longitudinal channel of the drive member. Next, a torque transmitting engagement is formed between the gate engaging structure of the portable driving device and an auger portion of the ski course gate.
