A body weight trainer fitness device allows for the strengthening and normalization of functional movement patterns for those who are not otherwise able. The device accomplishes this with the use of resilient strength bands which are provided in the form of heavy duty rubber bands of varying widths. The bands are selectively attached to a frame via selectively-moveable band holders. The device may then be used to offload the user's weight and thus decrease resistance or it can be used to increase the resistance of an exercise. The bands can be oriented to offload the user's body weight allowing a user to exercise with proper form. Once normal functional movement can take place without the bands, the device may be configured to utilize the bands as resistance to improve these functional motion patterns.

The present invention relates to a self-molding permanent agent and a method for proceeding free-rod and free-band type permanent, more particularly to a self-molding permanent agent comprising (a) a reducing composition containing a reducing agent reducing a disulfide bond of cystine on the hair and a molding stimulant spontaneously molding to fix a hair design; (b) a molding composition inducing to mold after reacting with the molding stimulant; and (c) a softening composition releasing the action of a molding stimulant, and a method for pressing a free-rod and free-band type permanent, which overcomes a disadvantage in the conventional method for pressing a permanent that needs to wear a curling device such as rods for a permanent (perm rod) or rubber band and improves to apply a wave set without a hair-curling device for a short time, since it has a self-molding feature.

A display that can be expanded from a collapsed position for storage and transport to an expanded position for free-standing operation and use. A spinal member is disposed between front and back panels such that in the collapsed position, the spinal member maintains the two panels substantially adjacent one another in a generally two-dimensional shape. Upon movement of at least a portion of the spinal member relative to the panels, parts of the spinal member bias the panels apart from one another to form an expanded, three-dimensional shape. This shape provides a sufficient footprint of the display relative to its height that the display can be free-standing. The cooperative relationship between the spinal member and the panels is such that no rubber bands or related elastic devices are required to maintain the display in the expanded position.

A film keyboard is sewn into an end of the sleeve of a jacket. A cable leads from it to a first plug-type connector, on whose opposite end a rubber band engages, said rubber band being supported in terms of forces at another point on the end of the sleeve. If the nebber band is located between the thumb and index finger, the first plug-type connector is thus inevitably held in such a position that it can easily be plugged into a second, corresponding plug-type connector of a mobile phone when the latter is held in the hand in the usual way. When not in use, the first plug-type connector is held concealed in the end of the sleeve.

Standard test methods using a fixed ring for determining one-dimensional consolidation properties of soils represent a subsurface condition where settlement and dissipation of excess pore pressure is possible only in vertical direction. This subsurface condition never occurs, as settlements and dissipation of excess pore pressures always occur in horizontal and vertical directions. Dr. Ramesh Gupta has invented a test device for determining three-dimensional consolidation properties of soils, using a flexible ring permitting displacements and dissipation of excess pore pressures in both horizontal and vertical directions, and affording determination of coefficients of consolidation in horizontal and vertical directions including three-dimensional coefficient of consolidation, and modulus of elasticity. The test device consists of a flexible ring consisting of filter fabric around the soil specimen, rubber membrane around the filter, circular segmented metal plates around the membrane and rubber bands or rings around the plates. Both incremental or triaxial type loading can be used with this device.

A flexible cover is formed from a rectangular sheet of plastic film material and a continuous elastic or rubber band. The sheet has a predetermined amount of material cut from each corner. The sheet is placed onto a table between four posts that extend from the table. The sheet is positioned so that a post lines up with each corner of the sheet. A rubber band is stretched across the four posts into a similar shaped rectangle and rests just above the sheet. The stretched rubber band now has four sides which correspond to the four sides of the sheet. The side edges of the sheet are folded inward and over the stretched band and heat sealed directly to the sheet. The band is now sealed within a pocket that is formed along the sides of the sheet. Each corner of the stretched band is released from its post, allowing the band to relax and pull the four corners of the sheet toward the center. This creates a generally circular cover with a near rectangular mouth which can be used on both rectangular and circular shaped containers or plates with similar sized openings.
