Abstract: A gyroscopic exercise device has a pair of handles attached to a housing. A user holds and rotates the handles along a cone-like path causing precession of a rotor, which is rotating about its spin axis, to provide resistance to the user. The device has a ring guide that holds ends of a shaft, which is coupled to the rotor. The periphery of the ring guide and the ends of the shaft are within a circular race defined by the housing. A motor attached to the ring guide drives a wheel that rotates the rotor about a spin axis by using energy provided by batteries in one of the handles. The energy passes through a conducting conduit that rotates about the precession axis. The ring guide, motor, and rotor can rotate together during precession of the rotor.

Abstract: A wrist exerciser includes an upper casing member and a lower casing member that are mounted to each other to enclose a rotor therebetween. The upper casing member has a top opening, which exposes a portion of the rotor. The rotor has opposite sides on which two opposite axles are mounted respectively. The axles are rotatably coupled to an outer ring. The outer ring comprises a resiliency device. The side of the rotor that faces the resiliency device is provided with a movable catching mechanism that is releasably, selectively, and operatively coupled to the resiliency device. Thus, when the rotor is initially rotated or is towed to take a linear movement by being put in contact with a fixture surface, the resiliency device builds up compression spring force, which, when the rotor is released, causes the rotor to rotate in a reversed direction and gaining auxiliary starting power and initial rotation speed.

Abstract: A revolution counter for wrist exerciser includes a generator module, at least a detection element pair, a wireless transmission module, and wireless receiver. The generator module, the detection elements, and the wireless transmission module are arranged between a rotor and a stationary casing of the wrist exerciser. The rotation of the rotor with respect to the casing induces a voltage in the generator module, which is supplied to the detection elements and the wireless transmission module. The detection elements detect the rotation of the rotor and generate a signal associated with data of the rotation to the wireless transmission module. The wireless transmission module converts the signal into corresponding data and transmits the data in a wireless manner. The wireless receiver receives the data and displays the data in a display device or transmits the data to an external electronic device.

Abstract: Three types of exercise grips provide for pivot-anchoring of an impinging body within them so that the impinger heads engage stretchable or non-stretchable exercise media extending upward through their tunnels. The first is a handgrip, the second, an exercise spool used in the manner of cross-country skiing or vigorous walking and the third, an ankle crescent-shaped grip for lateral repetition exercises of the legs. An impinger is caused to swing down to press against exercise media emerging from the grip's tunnel to provide a reliable of connection. Proper anchoring of the impinger within the grip assures its continuing presence to make adjustments and avoids its loss or misplacement. The handgrip permits of anchoring either within the body's interior or at its exterior, in which case, the impinger stem is caused to extend through a window cut therein.

Abstract: An exercising device for strengthening hands or limbs has first and second bladders containing fluid with first and second valves that couple the bladders to a fluid pressure gage. Squeezing the first bladder by the left hand causes easy flow through the first valve to the pressure gage in a first direction, whereas the second valve presents a high impedance to flow in the same direction into the right hand bladder, so that the measured gage impulse pressure is proportional to the flow rate of fluid through the second valve indicating left hand strength. Squeezing the second bladder by the right hand produces fluid flow in the opposite direction with the right hand strength being measured in like manner. Alternate bladder squeezing creates a pleasant rhythmic exercise routine and the peak gage pressure indicates progress. The valve configuration enables strength measurement of the weak and the strong with one device.
