Abstract: A color swatch arrangement for use in selecting colors for four-color offset printing, and a method for creating such an arrangement, involves dividing the visible spectrum into a plurality of distinct hues, and determining the proportions of yellow, red, and blue dot densities needed to create color swatches of each distinct hue. A series of lighter-and-lighter tint swatches associated with each distinct hue are created by reducing each of the yellow, red, and blue dot densities in steps. A series of darker shade swatches is created by adding a proportion of black dot density to each distinct hue and all the stepped lighter tints created from it, and a series of darker-and-darker shade swatches are produced by adding greater proportions of black dot density in stages to all the stepped lighter tints.

Abstract: An isoinertial lift machine is described which can be used to evaluate and train patients in the static and dynamic lift modes. The machine consists of an arm which can be positioned on a vertical column. At the end of the arm, various size attachments and handles can be attached. The arm also carries a force sensor that measures the forces applied to the handles. In the static mode, the arm is positioned at a desired height and locked in place. The patient lifts on the handle, and the force sensor registers the lifting force. Since the handle does not move during the lift, the mode is called static. In the dynamic mode, the arm/handle moves in the vertical direction during the lift. A resistance mechanism is used to resist the lifting force applied by the user at the handle. The resisting force is always pulling the arm down, both in the lifting and the lowering motion. The resisting force remains constant throughout the range of motion during lifting.

Abstract: A buttocks exerciser is formed of a one-piece housing having a generally planar upper surface and rectangular configuration. The exerciser further defines a concave undersurface and a triangular cross-section pivot support extending downwardly beneath the headrest portion. The pivot support terminates in a transversely extending pivot edge about which the exerciser pivots. A pair of fastening belts are secured to the lower portion of the exerciser and are movable for position adjustment. The user places his or her torso upon the exercise with head overlying the headrest and hips near the bottom edge. The user then fastens the attachment straps across the user's lap and hip portion and thereafter, with feet placed near the bottom edge, performs a wrestler's bridge-type exercise in which the exerciser pivots about the transverse pivot edge.
