Abstract: A collapsible measuring and cutting craft table enables cutting, measuring, and stowing fabric and craft materials from a foldable, height-adjustable, and mobile work surface. The craft table comprises a large, flat work surface having a center panel and two hingedly attached drop leaf panels that fold down for storage. Center support members support the center panel in a horizontal position at the desired working height. Two center support members supports the center panel of the work surface. The outer support members pivot outwardly to a support position to support the drop leaf panels. The outer support members pivot inwardly to a collapsed position to fold the drop leaf panels down perpendicularly relative to the center panel. The center support members telescopically adjust in length to height adjust the work surface. The support members terminates at wheels for mobility. Meshed baskets slide along rails that run between the center support members.

Abstract: A device and method for measuring the amount of knee extension loss, hyperextension, or extensor length associated with arthritis, trauma, surgery or other medical conditions. This device and method includes measuring the difference in heel heights of a patient while patient is lying prone on a table with their legs, at the level of their knee caps, off the table. This device and method also measures extensor length in a patient's knee joint, by assessing heel height difference while a patient is lying prone on a table with a prone knee bend. This device and its methods provide accurate distance measurements that correlate to knee straightness and flexibility; these distinguishing metrics are unattainable by a standard “disc” goniometer. In addition, this device permits convenient measuring of a knee's mobility for two unique perspectives, namely in prone with legs straight or with a knee bent.

Abstract: An apparatus for measuring compound angles. This apparatus makes use of the standard T-bevel square, which is capable of measuring only a single angle. The invention is a compound angle blade with a split collet joint. The compound blade attaches by replacing the bolt of the T-bevel with fastening means attached to the split collet joint of the invention. This fastening means secures both the compound angle blade and the standard T-bevel square blade. The split collet joint which is attached perpendicularly to the main body of the T-bevel moves in a 360 degree radius parallel to the main body of the T-bevel. The compound angle blade is capable of rotation in approximately a 180 degree radius relative to the split collet joint. The combination of the rotation of the split collet joint and the compound angle blade allows for compound angle measurements both perpendicular and askew relative to the angle of the standard T-bevel. The angles of both blades are fixed by the same fastening action.
