Methods of regenerating tissue at the site of a tissue defect in a mammal are also provided.
Abstract:
A method and system is disclosed herein for a communications system. In one embodiment, the system comprises a hub, a plurality of endpoint devices, and at least one routing endpoint device, from among the plurality of endpoint devices. In one embodiment of the system, the plurality of endpoint devices communicate through the hub in the system. Furthermore, in one embodiment of the system, the at least one routing endpoint device is to route, at least part of the time, endpoint device communication within the communications system.
Abstract:
A wireless communication system using mobile devices or repeaters are described. In one embodiment, a communication system comprises a base station and a plurality of terminal devices, wherein at least one of the terminal devices operates, at least a part of the time, as a repeater.
Abstract:
A system and method for printing an ink jet ink based on solvent, oil, or both solvent and oil in selected areas of nonabsorbent and semi-nonabsorbent substrates includes applying a coating receptive to the solvent- and/or oil-based ink jet ink in the selected areas, for example with printing station having a printing and drying unit for applying the ink-receptive coating in the desired area or areas of the substrate and then drying the coating, and printing an aqueous ink jet ink in the coated area with an ink jet printer. Variable print may be printed with the in jet ink in a high speed process.
Abstract:
A printing method includes steps of applying an ink-receptive coating to a substrate; printing an actinic radiation-curable ink jet ink over the coating; and curing the printed ink jet ink. An article printed by the method has a ink-receptive coating layer with a cured print. An apparatus for carrying out the method includes a coating station at which the ink-receptive coating is applied to a substrate, an ink jet printhead at which the energy-curable ink jet ink is applied, and a source of actinic radiation for curing the applied ink. The ink may be applied in sufficient amount to achieve a color density comparable to that obtained using other printing processes such as flexographic or gravure printing processes. The ink-receptive coating layer may be of a thickness sufficient to provide improve surface smoothness and/or reduced drop spread relative to an uncoated substrate.
Abstract:
A document sheet generally comprised of a sheet of material, preferably paper stock, having an indentation area recessed in its front surface. In one portion of the indentation area, an object is secured. The other portion of the indentation area is configured and adapted to allow for the insertion of a tool for easier removal of the object from the sheet.
Abstract:
A fire extinguishing and fire retarding method is provided comprising the step of confining a fire extinguishing and fire retarding agent in slurry, liquid or gaseous form within a shell wherein the shell comprises such an agent in solid form. An agent such as ice water, or liquid carbon dioxide is useful when employing the shell as “non-lethal” device. The solid shell is sublimable and will burst upon impact or upon exposure to the environmental conditions at the target site to release the contents of the shell as well as the fragments of the shell onto the target site.
Abstract:
Disclosed are devices, systems, and methods, including an oxygen delivery device that includes an oxygen delivery module to produce at least concentrated oxygen, and a gas moving device to deliver air to the oxygen delivery module. The gas moving device includes at least one piston rotatable inside a first chamber defined in a housing, the rotational movement of the at least one piston inside the first chamber resulting in varying pressure generated in a first portion of the first chamber, and a vane member rigidly coupled to the at least one piston, the vane member being configured to move inside a vane chamber defined in the housing, the piston and the vane rigidly coupled to the piston define the first portion of the first chamber and a second portion of the first chamber.
Abstract:
Systems and methods of applying a gaseous inhibitor into a printing region to hinder the curing process of ink on the print heads caused by the presence of stray light in the printing environment.
