Abstract: A miniaturized inexpensive vibration generator using rotary bodies having unbalanced weights with no absolute encoders provided on the rotary body driving means. Rotary bodies having unbalanced weights are disposed in an opposed state. Members to be detected are fixed to the rotary bodies so that the members to be detected have a predetermined positional relation with the relative weights and rotation detectors are provided fixedly in the positions close to the loci of the rotational movements of the members to be detected, and adapted to output signals representative of what are detected thereby in the form of pulses each of which is generated every time each of the members to be detected passes the relative rotation detector, i.e., every time each member to be detected is revolved 360.degree., a phase difference computing element computes a phase difference between the unbalanced weights on the basis of the signals from the rotation detectors.

Abstract: A method for applying a mechanical massage while the back of a user is against the back rest of a chair or lying on a bed uses a massage mechanism unit having a pair of spaced parallel arm members and a massaging wheel rotatably supported on one end of each of the arm members. The massaging wheels are positioned on the back of the user on opposite sides of the spinal column. The massaging wheels are then simultaneously moved and turned in the same direction from left to right and right to left while moving back and forth along sinusoidal paths on two sides of the spinal column. The pressure exerted by one of the massaging wheels on the back is reduced by moving the massaging wheel away from the back as the massaging wheel moves closer to the spinal column. The pressure exerted by the other massaging wheel is increased by moving the massaging wheel toward the back as the massaging wheel moves away from the spinal column. The massaging wheels thus alternatingly move toward and away from the spinal column.

Abstract: A system for alternately applying and releasing pressure on the muscles of the back comprising a plurality of spaced elasomeric balls that are rotatably supported by a carrier. The balls are positioned between the user's back and a vertical surface with the balls orientated on opposite sides of the spinal column. Vertical movement of the user's back due to bending of the knees effects movement of the balls relative to the user's back and controlled massage of the user's back muscles.

Abstract: In accordance with the invention, a body pressure massaging device is provided which permits a user to massage his back by placing said device between his back and a flat surface. The device comprises a threaded cylindrical dowel which is used to assemble a central narrow circular element having a shaped surface together with a pair of rounded end elements. The central narrow element has a hollow center with threads that mate with the threaded cylindrical dowel so that the central element may be mounted anywhere on the dowel. On each side of the central narrow element there is mounted on the dowel a rounded end element or bell shaped cap. The surface of each of the bell shaped caps has a raised bulbous ridge around the largest circumference of the cap. Each cap has a hollow cylindrical region with threads mating with the threads of the cylindrical member for mounting each cap a specific distance from the central narrow element.

Abstract: A force-sensitive sound-playing condom comprising: a condom body (10) having a distal end and a proximal end, and a miniature force-sensitive sound-playing unit (14) attached to the condom at its proximal end. The proximal end of the condom is made in the form of a semirigid rim (12) having a lower part with an opening (16) coinciding with the cavity of the condom, and an upper part extending radially upwardly from the body of the condom and supporting the sound-playing unit (14). The latter contains a chip-controlled piezoelectric sound transducer which plays a melody or voiced message when during intercouse the contacts (28 and 30) of the sound-playing unit (14) are closed and the transducer is activated.

Abstract: A condom comprising an elongate sheath, which may be of tubular form or alternatively of baggy- or pouch-type, which is rolled or rollable on a roll ring having applied thereto a material such as a lubricant, contraceptive, and/or medicament, and wherein the proximal portion of the condom is provided with openings therein, such that the roll ring can be squeezed on the applied condom to cause exudation of the applied material through the proximal openings of the sheath. The rolled condom comprises a rolled portion circumscribing a distal end portion of the condom, thereby forming a cavity into which a "plug" of suitable material may be disposed, as a reservoir means for containing lubricant, contraceptive, and/or medicament, as well as providing an orientation-indicating means so that the condom is not misapplied to the penis of a wearer. The sheath may be formed of natural latex rubber or synthetic polymeric materials, e.g., thermoplastic elastomeric material.

Abstract: An osteosynthesis spinal device comprises two rods (1, 2), anterior and posterior rods, respectively. Plates (4) for fixation of the anterior rod (1) to the extreme vertebral bodies, for example T12 and L3, have an arched surface corresponding to the anterolateral anatomy of the vertebral bodies. The plates (4) are equipped with screws (14) for locking the rod (1) and screws (5) of the cancellous bone type. Screws (3) ensure the osseous anchoring of the posterior rod (2) and bars (6) for transverse connection of the rods (1 and 2) constitute with the rods, a rigid frame assembly. The anterior rod (1) reinforces the stability and the rigidity of the assembly and is advantageously embedded in a furrow (30) made in the vertebral bodies which is subsequently covered with the periostrum.

Abstract: A patella osteotomy guide comprising a plier-like appliance with curved jaws for grasping a patient's patella. A row of teeth faces inwardly from the jaws. The teeth are generally of pyramid shape, but a vertex of each tooth lies in a plane containing a bottom side of the respective jaw. Each of the jaws has an integral saw capture slot and the tips of the jaws are extended. A rotating, calibrated stylus measures the position of the patella with respect to the integral saw capture slots. The rotating stylus also functions as a pivot or fulcrum about which the jaws and handles of the osteotomy guide rotate. Handles for the osteotomy guide are offset from the plane of the jaws. The rotating stylus can be displaced up and down and then locked into a selected position using a draw bar and captured balls. A bowed retaining ring imparts a certain amount of pre-load to the stylus and draw bar assembly to hold the assembly in a selected position.
