Abstract: A jumping shoe includes a pair of spring platforms, extending downward under the heel of the user and under the ball of his foot. Each spring platform includes a guiding structure, a sliding platform mounted to slide on the guiding structure, and a spring pushing the sliding platform downward. Preferably, the sliding movement is obtained through the use of an inner cylinder sliding within a cavity of an outer cylinder.

Abstract: A device for determining whether a rotating stream of water from a sprinkler has been successfully jumped by a person at a player position includes a first sensor generating an first signal as the stream of water passes a first location and a second sensor generating a second signal as the stream of water passes a second location, which is aligned with the player position. The device determines whether the second signal follows the first, indicating whether the stream of water has been blocked by the person, having failed to jump. The device then provides an audible of visible indication as a result of this determination. The device may also display a count of successful jumps.

Abstract: A support fixture for setting a fractured distal radius includes a housing having a strap for fastening the fixture to the patient's forearm, a sliding section, sliding within the housing as a screw is rotated, and a pivoting section extending from a distal end of the sliding section. The sliding section also includes a structure for supporting the patient's wrist. The distal end of the pivoting section includes a pair of fingertraps. Two of the patient's fingers are held in the fingertraps, while an extension force is applied between his forearm and hand through the rotation of the screw, and while his hand is twisted by adjusting the angle of the pivoting section to increase the gap between fractured sections of bone, causing reduction of the fracture to occur.

Abstract: Apparatus is configured to provide an alarm perceivable by a user when an increase in a level of force applied to a foot exceeds a threshold value determined by a variable resistance. The level of force is determined from a pressure established within a transducer in an insole placed, for example, within the shoe of the user. This pressure is converted into an electrical signal within a pressure transducer within a control box. This electrical signal charges a capacitor to produce a voltage which is compared with a voltage level corresponding to the threshold value. The result of this comparison is used to determine when the alarm is provided.

Abstract: A tissue pressure measuring system is disclosed. The system includes a syringe with a cylindrical passage and means for connecting a tissue invasion device in fluid communication with the cylindrical passage. A plug is present within the cylindrical passage and has a diaphragm therein.
