A portable exercise device includes a first body and a second body. The exercise device also includes a support structure pivotably connecting the first and second bodies. The support structure is configured to move between an engaged position and a disengaged position. The device also includes a resistance mechanism configured to resist movement of the first and second bodies toward one another when the support structure is in the engaged position. When the support structure is in the engaged position, the first body is positioned substantially parallel to the second body such that in a first open, in-use configuration of the device, the first body has a first neutral position relative to a pivot axis and in a second open, in-use configuration of the device, the second body has a second neutral position relative to the pivot axis.

A balance trainer having a dome and a base formed integrally is provided. Also, a mold assembly for manufacturing the balance trainer that has a dome mold, a girdle, and a cover is provided. The girdle is sleeved on the dome mold and the cover is fixed on the girdle and thereby a cavity is formed in the mold assembly. Furthermore, a manufacturing process of the balance trainer is also provided. The process has the following steps: preparing ingredients of the dome and the base; feeding the ingredients of the dome into the dome mold; fixing a membrane on the dome mold via the girdle; feeding the ingredients of the base; sealing the ingredients via the cover; and then rotational molding. With the process and the mold, the rotational molding step can mold two materials at the same time, so the product can have two parts with different hardness.

An exercise device having a unique asymmetrical shape with rounded ends of differing radii to provide stability and added resistance.

A method for operating a seat system, where the seat system includes a vehicle seat having a plurality of controllable moveable elements integrated into a seat cushion that forms a seat surface and/or into a seat back, includes prompting, during an activated muscle training program, a user on the vehicle seat to exert a pressure with a specific body region of the user on a predetermined region of the vehicle seat in which at least one of the plurality of controllable moveable element is arranged and determining a local and a temporal deviation between a pressure exerted by the user as an input signal and a specification as an output signal.

An antimicrobial sportsball includes a ball carcass having an interior cavity and an antimicrobial ball cover, covering the ball carcass. The antimicrobial ball cover contains and releases antimicrobial agent to the ball surface and the environment. The ball carcass includes an inflatable bladder adapted to be inflated into a designated size and shape and a cushion layer covering the inflatable wound or lined bladder, so as to provide additional cushioning effect and form channels.

An apparatus integrating a zoetrope including a panel made of a transparent material and strips made of an opaque material that attach to the panel at equal distance from one another. The strips include a series of graduated images at the inner side of the panel. The series of images differ slightly and progressively from one to the next. The transparent panel and the strips present a zoetrope in which the transparent panel acts as slits allowing a user to view the images on the strips at the inner side of the panel, and the strips act as a series of segments obscuring the view of the inner side of the panel. The user rotates the panel at an appropriate speed to view the images alternatively through the transparent panel and obscure the images by the strips in rapid succession creating the perception of an animation of the images.

A muscle-strengthening passive and active motion device includes: a joint supporter supporting a body part that is bendable or stretchable with a joint region; a driver driving the joint supporter by being combined to the joint supporter; and a controller controlling the driver, wherein the controller is capable of accelerating or decelerating a driving speed of the joint supporter.

The present specification discloses an exercise system comprising a stable support purchase, such as a ballet barre, and an unstable support apparatus, such as a ball or a roller, wherein an individual may support a limb on the unstable support apparatus and selectively contact the stable support purchase for balance while performing an exercise, such as a ballet position, and an associated method comprising the steps of positioning at least one limb on the unstable support apparatus and simultaneously performing the exercise.

A relief system for at least partially relieving the body weight of a person includes at least one first fastening device for fastening a first end of a first support device and at least one second fastening device for fastening a second end of the first support device which are formed on a cuff, such that an equally distributed tensile force is exerted on the cuff at the first fastening device and second fastening device when the first support device is guided through a guide device during a movement of the cuff when loaded by at least part of the body weight of the person. This advantageously permits a simple connection in particular of a bedridden patient to the relief system, without the patient first having to be moved, without other medical/therapeutic devices being disturbed, and without limiting the patient's stepping/walking movement.
