摘要:
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.

Described herein are various embodiments of differential air pressure systems and components for differential air pressure systems. The air pressure systems comprise a chamber for receiving at least a portion of a user's body. Pressure in the chamber can be changed to adjust force on the user's body. Described herein are various methods and related structures for sealing a user into a pressurizable chamber. Also described herein are various methods and related structures for changing the shape and/or height of the chamber. Described herein are various types and configurations of chambers and support structures for chambers. Also described herein are various methods and related systems for treating various conditions using the differential air pressure systems, including but not limited to obesity, cardiac disease, multiple sclerosis, cerebral palsy, or Down Syndrome.

A height-adjustable DAP exercise system is provided having a support platform, an inflatable enclosure secured to the support platform at a base opening through the enclosure and extending vertically therefrom when inflated, and a top frame attached to the enclosure at an enclosure top opening. The DAP system further includes adjustable lift restraints each having a restraint length between first and second ends and configured for adjustment between a first restraint length and at least one second restraint length, in which each first end of each lift restraint is attached to a middle portion of the enclosure and each second end is attached to the top frame or the base. The enclosure height is adjustable between a first and second enclosure height responsive to adjustments for lift restraint lengths. The system also includes a low height safety harness for the top frame and related methods.

摘要:
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).
摘要:
A system is provided by applying pressure to a portion of a body of an individual in a chamber having an aperture along a vertical axis for receiving the portion of the body of the individual. A pressure sensor is coupled to the chamber for measuring a pressure inside the chamber. A negative feedback control system, calibrates, adjusts and maintains the pressure inside the chamber.
