Moreover, the annular magnetic field generating source can easily be embedded a predetermined depth and at predetermined positions in the pressure roller is not exposed on the surface of the pressure roller.

Abstract: A vibrating massager includes a housing and an elastic strap, which is fastened into a loop to hold a protrusion extending from a surface of the housing against a pressure point of the human body. Mechanical vibrations, produced by a small electric motor spinning an eccentrically mounted weight, are transmitted to the protrusion. The motor is driven according to a pattern of pulses, between which the vibrations are interrupted. The length of time between vibrating pulses is adjusted with a first know on the device. The speed of the motor is adjusted using a second knob on the device, varying the frequency and amplitude of the vibrations. An extension strap is used to facilitate attachment of the strap around larger body members such as the head, as well as around smaller body members, such as the wrist.

Abstract: A hydrotherapy bed includes a substantially water-tight enclosure having an open top. The top of the enclosure is covered by an upper and lower layer of thin rubber having an intermediate layer of thixotropic gel approximately one half inch thick. The rubber layers are mounted in a peripheral groove using a strip of T-shaped molding and a supporting net is mounted beneath the lower rubber layer in another peripheral groove by attaching edge loops of the net to a plastic coated half hinge which is inserted into the peripheral groove. A pair of parallel tracks is mounted inside the enclosure and an array of upwardly directed water jets is carried on a cross member which is movable along the tracks. The cross member is coupled to an endless cable wound around pulleys mounted at ends of the tracks. One of the pulleys is coupled to a motor which drives the cross member along the tracks. The cable is kept from crossing over itself on the drive pulley by threading it through a TEFLON.RTM.
