A therapeutic, fitness and sports enhancement device which includes a cylindrically shaped body having a predetermined density and predetermined diameter, the body including a plurality of projections of a predetermined shape. One or more of the predetermined density and the predetermined diameter in combination with the predetermined shape of the projections optimize mobilization of soft tissue structures of the human body.

An integrally-formed three-dimensional (3D) bio-printing system capable of alternate feeding of multiple materials, comprising: an optical imaging unit and a light path conversion unit, wherein the optical imaging unit comprises an image processing unit and a projection unit, the image processing unit segmenting a 3D modeling graphic of a printed subject to form image information, the projection unit converting the image information into one or more optical images, and the light path conversion unit projects the imaged light paths into bio-ink that can be cured by light, so that the projected image can cure the bio-ink by means of the focus of light.

This disclosure describes hydrogel three-dimensional printing kits, methods of three-dimensional printing hydrogels, and hydrogel three-dimensional printing systems. In one example, a hydrogel three-dimensional printing kit can include a particulate build material and an aqueous agent. The particulate build material can include from about 90 wt % to 100 wt % of a mixture of a powdered polyhydroxylated swellable polymer dry blended with powdered water-soluble crosslinker that is reactive with hydroxyl groups of the polyhydroxylated swellable polymer to crosslink the polyhydroxylated swellable polymer. The aqueous agent can include water and an organic co-solvent, and the aqueous agent may not include the crosslinker.

Provided is a foam blend incorporating a phase change material for foaming and making a foamed shoe body, comprising a thermoplastic material, a blowing agent, a crosslinking agent and a phase change material; the phase change material is added in an amount based on the total content of the thermoplastic material, and is mixed with the thermoplastic material in an amount of no more than 15 phr, wherein the transition temperature of the phase change material is 45 C.-100 C. Another embodiment provides a method for making a foamed shoe body from a foam blend, comprising the steps of filling the foam blend into a mold for heating and foaming to form a semi-finished product of the foamed shoe body, and placing the semi-finished product of the foamed shoe body in an aging environment for shrinking and molding into a finished product of the foamed shoe body. The method thus can shorten the time of cooling and shrinkage of the foamed shoe body and save energy consumption in the manufacturing process.

A crosslinked polyolefin separator and a method of making the same are disclosed herein. The method includes mixing a polyolefin, a diluting agent, an initiator, a crosslinking catalyst, and inorganic particles surface treated with an alkoxysilane containing a carbon-carbon double bonded group in an extruder to obtain a mixture, and then reactively extruding the mixture to form an extruded silane-grafted polyolefin composition; molding and orienting the extruded silane-grafted polyolefin composition in the form of an oriented sheet; extracting the diluting agent from the oriented sheet to obtain a porous membrane; thermally fixing the porous membrane to obtain a thermally fixed porous membrane; and crosslinking the thermally fixed porous membrane in the presence of moisture.

A three-dimensional geometry of a thermal interface body may be customized to substantially fill an irregular gap along a thermal dissipation pathway in an electronic package. The thermal interface body is fabricated through an additive deposition process, wherein sequential patterns of thermal interface material are coherently connected to other deposited patterns of thermal interface material.

A glass run channel includes a header and one or more inserts molded into the header. The header includes an upper header wall, an outer header wall extending from the upper header wall, and an inner header wall extending from the upper header wall opposite the outer header wall. The inserts include an upper insert wall provided within the upper header wall, an insert body extending from the upper insert wall and provided within the inner header wall, and a hook wall extending from the insert body. The header fully surrounds the inserts. A portion of the header surrounding the one or more inserts defines a hook for a sunshade.

A plant for producing an extruded silicone intermediate has a mixer/extruder for mixing and subsequently extruding a silicone compound for producing a raw silicone extrudate. A heating apparatus of the plant serves for crosslinking the raw extrudate to give the crosslinked silicone intermediate. The result is a plant with which a silicone intermediate of this kind can be produced more economically.
