Abstract: An inflatable unweighting enclosure for an exercise device is provided formed from a pair of opposing sheets attached to each other by a seam along a closed shape at their perimeter portions, each of which has a top region, an opposite base region, and central region. A trim path interrupts each articulated shape at the base region that defines a perimeter of a base opening for the enclosure when inflated, in which the base and base opening are substantially planar and the base perimeter defines an enclosure inlet. When inflated, the pair of flexible sheets expand laterally apart to define an enclosure inner space and form an elongate, disc-shaped structure interrupted by the base opening. The base opening attaches to a base support of the exercise device, which is shaped and sized to orient and support the enclosure vertically for providing unweighting to a user attached to a top opening.

Abstract: An inflatable belt 100 for use in a BFR system with an outer belt material 102 hermetically sealed to an inner belt material 101 along a perimeter, thereby forming at least one inflatable chamber 103, the inflatable chamber having an input port 104 for accepting a gas into the chamber, the inflatable belt further comprising a first fastening means 110 in communication with the outer belt material, for attaching to a second fastening means 111 in communication with the outer belt material, thereby locking a circumference of the inflatable belt, when wrapped around a user's limb.

Abstract: And adjustable sports net system comprising a plurality of ground anchors (105), two standard assemblies (108), elastic guy line assemblies (107) connecting the ground anchors to the standards, and a net fabric (101) disposed between the two standard assemblies. The net fabric (101) is adjustable in length and height, independent of initial placement of the standard assemblies (108). The standard assemblies (108) may deflect substantially upon impact from a game object (503) but return to a nominal position because of the elastic spring elements (110) in the guy line assemblies (107). The energy from such impact is absorbed over a longer time period, and the peak forces are kept lower for use of cheap, light materials, for system that is lightweight, fast to set up by a single person, and cost effective to manufacture. A safety structure provides protection to the consumer from inadvertent pullout of each ground anchor (105).

Abstract: Methods, apparatus, and systems for calibrating differential air pressure systems are described. The methods, apparatus, and systems may be adapted for physical training of an individual, e.g. as a training tool to improve performance or as a physical therapy tool for rehabilitation or strengthening. The differential air pressure systems comprise a chamber for receiving at least a portion of a user's body. In one embodiment, a method for calibrating a differential air pressure system for predicting effective body weight of a user versus system pressure is described. In certain variations, the methods, apparatus and systems may comprise adjusting pressure in the system until one or more force values are reached. The methods described herein may comprise determining a relationship between body weight force and pressure, allowing the user to set a pressure or a parameter correlated with pressure to achieve a desired effective body weight.
