Abstract: A massage tool can include an axle including a root outer diameter, a center stop protrusion, end stop protrusions located at opposing ends of the axle, and at least one set of positioning protrusions located between the center stop protrusion and at least one of the end stop protrusions. An inner positioning protrusion of the at least one set of positioning protrusions is located axially closer to the center stop protrusion than an outer positioning protrusion of the at least one set of positioning protrusions. The outer and inner positioning protrusions each protrude from the root outer diameter of the axle a distance that is less than a distance that the center stop protrusion and the end stop protrusions protrude from the root outer diameter of the axle. Two massage elements each contain a center bore having a bore diameter substantially equal to the root outer diameter of the axle.

Abstract: A stool can include a base including at least three legs with each leg including a non-slip member and a spring-loaded caster. A lower helical spring may be coupled to the base. A connecting member may comprise a first end coupled to the lower helical spring, a second end opposite the first end, and a central axis that extends between the first end and the second end. An upper helical spring may be coupled to the second end of the connecting member. A rotational joint may be coupled to the upper helical spring. A seat may be coupled to the rotational joint and configured to rotate about the central axis of the connecting member. The base, lower helical spring, upper helical spring, rotational joint, and seat may share a common vertical axis with the central axis of the connecting member when at rest.

Abstract: A massage roller may include a hollow cylindrical body with a cylindrical core and a plurality of massage protrusions each extending outwardly from the cylindrical body. Each massage protrusion may be substantially centered within a different polygonal region of a polygonal tessellation of the surface of the cylindrical body. The massage protrusions each may have a base, a filleted peripheral edge extending around the base, a concave cap opposite the base, and a plurality of walls equal in number to the edges of the polygonal region in which the protrusion is substantially centered. Each massage protrusion may also include an axial cross-section which is substantially polygonal, and has the same number of edges as and is substantially aligned with the polygonal region in which the protrusion is substantially centered.

Abstract: A roller which an individual may use to perform a variety of self-applied exercises for massage, myofascial release and other exercises. The roller is cylindrical having a resilient outer surface on which are a plurality of axially spaced, circumferentially extending bands of similar projections which manipulate the body of the individual when the individual rolls against the surface of the roller. The projections are equally circumferentially spaced in each band extending around the cylindrical body. The material and shape of the projections are selected to provide greater resistance to bending or flexing to forces applied axially than to tangentially applied forces.

Abstract: A massage device mounting system may include two mounting elements, each with a slot for receiving a removable massage bar with a cylindrical shaft and two opposing bar ends mounted within the slots. A massage device is pivotally coupled to the cylindrical shaft and includes a bore through the central axis of the massage device. A massage device mounting system may also include an adjustable support for mounting the massage device within a doorway or for supporting the massage device adjacent to a surface, such as a wall or a floor.

Abstract: A massage device mounting system may include a massage ball with a plurality of massage fingers positioned across the ball aligned with the vertices of a pentakis dodecahedron. The massage device mounting system may also include a mounting body removably entrapped between a plurality of massage fingers on the massage apparatus. The mounting body may include a mounting shoulder with a continuous or discontinuous ring. The mounting shoulder may also be circular shaped or polygonal shaped. The mounting body may also include one or two handles coupled to the mounting shoulder. Some mounting bodies may also include a mounting base that can mount to a mounting wall.

Abstract: A massage device is disclosed and may include a substantially solid body with an array of at least twenty, and in some cases thirty or thirty-two or more, massage fingers each with an outward tip, an inward base and a center axis, the center axis extending to a center of the body. The massage fingers are spaced about the body at substantially equal distances from each of at least three, and in some cases up to five or six, massage fingers nearest to each massage finger such that the center axis of each massage finger is spaced and positioned to correspond to a location of one of at least twenty vertices of a polyhedron, in some cases a pentakis dodecahedron, and aligns with a vertex axis extending from a polyhedron center point through one of the vertices of the polyhedron.

Abstract: An improved wet scrubber tray provides increased resistance to vibration-induced cracking. The self-supporting tray eliminates wastage of raw material, and additional internal stiffeners added to the tray make multiple intermediate stiffeners. The connection of the intermediate stiffeners to the perforated bottom plate is changed to eliminate the shop weld in the bottom plate. The holes in the perforated bottom plate are moved away from the boundaries of the tray to reduce their influence on boundary conditions. Trays are held down by plate material that is attached to the support grid, but not to the trays. Three field welds are applied to the sides of each tray to hold the trays in place relative to each other and are strategically placed to allow adjacent side stiffeners to act together as a composite section. Elastomeric material is used at the tray-to-grid attachments increases the damping of the system.

Abstract: An improved wet scrubber tray provides increased resistance to vibration-induced cracking. The tray is self supporting to eliminate wastage of raw material, and additional internal stiffeners added to the tray make multiple intermediate stiffeners. The connection of the intermediate stiffeners to the perforated bottom plate is changed to eliminate the shop weld in the bottom plate. The holes in the perforated bottom plate are repositioned so that they are moved away from the boundaries of the tray to reduce their influence on boundary conditions. The thickness of the tray material may be increased to lower the vibratory stresses. The mechanism for holding the trays themselves within the spray absorber tower is changed so that the trays are now held down by plate material that is attached to the support grid, but not to the trays.

Abstract: A jacket for an inflatable bladder such as an exercise ball. The jacket has a durable cover with an access section having an inner panel defining an access opening. Outer panels overlie the inner panel and have edges which extend across the opening and are provided with closures. In use, the outer panels may be separated at fasteners so a bladder may be removed or inserted through the access opening. The inner panel and the outer panels may be a woven material with their weave oriented to resist distortion when the bladder is inflated and to assist in securing the closure. The cover may be any suitable material such as a coated nylon providing durability.

Abstract: A self supporting header has a horizontally extending header pipe of fiberglass reinforced plastic with a horizontal axis and a flange of fiberglass reinforced plastic connected to an outer surface of the header pipe by at least one web and extending along at least part of the horizontal extent of the header pipe. The at least one web extends vertically from at least one of the top and bottom of the header pipe and is connected to the flange. A reinforcing member or material is embedded in at least one of the flange and the at least one web and that has a greater modulus of elasticity than a modulus of elasticity of the fiberglass reinforced plastic of the header pipe reinforces a cross-section of the header for increasing the self supporting strength of the header. The reinforcing member may be made of metal or a carbon composite material.

Abstract: A method of assisting individuals in making food choices by providing two nutritional indices. One is a numerical expression of a food's overall nutrient density and the other is a separate numerical expression that relates to a food's caloric density that is a prediction of the satiating effect of a food. A visual aid in the form of a graph or chart is provided so individuals using the indices can refer to the chart to determine food selections in accordance with the individual's dietary goals.

Abstract: A system, software and a method for estimating the Glycemic Load of foods are provided. A multivariate statistical analysis is performed on a known data set of Glycemic Load values for foods to yield a mathematical relationship that best fits the data. The mathematical relationship is then used to calculate an estimation of the Glycemic Load when a food's Glycemic Index (and, hence, Glycemic Load) is unknown based on the food's levels of known nutrients. The estimated Glycemic Load can then be applied to dieting.
