The resistance band couples to the exercise brace such that the resistance band creates a resistance to pivoting movement between the first frame member and the second frame member.

An exercise device is provided for enabling a user to obtain a full body workout. By attaching the device at selected positions on the hands, feet, arms, legs, or torso, different muscle groups of a user's body can be isolated for training and strengthening purposes. The exercise device includes two or more pieces of tubing material fitted together in a telescoping manner. Pressurized air within the tubing provides a user with resistance to movement in order to tone and strengthen the muscles. At one end of the telescoping tubing material is a handgrip and at the other end is a strap of a suitable resilient or elastic material that allows a user to securely place a foot or hand in for exercise purposes.

A twist pin is used as an interconnect interface to conduct signals to and from an electronic component. The twist pin includes a bulge which establishes compressive contact force with a sidewall of a via in which the twist pin resides, and the resulting force resists movement of the end of the twist pin away from the electronic component to assure good signal conductivity. The arrangement may be used as a test socket for testing integrated circuit components or permanently docking electronic components.

The ball may sit on top of a swivel plate, so that dynamic motion and counterbalancing are attainable for a variety of ergonomically beneficial seating styles.

A method and system for fitting a compression stabilized prosthetic socket for a patient having an amputated limb and a remaining portion that includes a first socket portion for contacting a patient's remaining portion of a limb, and a second socket portion for attachment of a prosthetic device. The first socket portion has compression portions having a radius for compressing portions of the patient's remaining portion of a limb, and relief portions receiving any portions of the patient's remaining limb which bulge upon the compression applied by the compression portions. The relief portions may be formed as openings or as enlarged radius portions. The fitting method and system can include use of a mechanism to compress bar surfaces against the limb in areas selected to receive compression portions in order to prepare an image for creating the first socket portion.

A molded contact lens comprising a stiffer optic zone relative to the peripheral zone of the contact lens provides an optical element for correcting astigmatism without the need for or substantially minimizing the need for the correction of rotational misalignment. The higher elastic modulus optic zone vaults over the cornea thereby allowing a tear lens to form. The tear lens follows or assumes the shape of the back surface of the contact lens. The combination of the tear lens and the optical zone provide an optical element for correction of refractive error.
