Abstract: The present application is drawn to a synthetic, polymer hydrogel-based material, which is able to actively induce the body's natural hemostatic coagulation process in blood or acellular plasma. The present invention provides the development of a primary amine containing polymer hydrogel capable of inducing blood coagulation and delivering therapeutics for hemostatic or wound care applications, and a method of forming such a primary amine containing polymer hydrogel capable of inducing the blood coagulation process. The primary amine containing polymer hydrogel is able to achieve the same end result as biological-based hemostatics, without the innate risk of disease transmission or immunological response, and at a fraction of the price. Furthermore, due to its inherent hydrogel-based design the material has the capability of arresting blood loss while simultaneously delivering therapeutics in a controlled manner, potentially revolutionizing the way in which wounds are treated.

Abstract: An ink jet imaging system comprises a heated imaging drum that rotates in at least one direction, a print head for ejecting ink onto the heated imaging drum as it rotates past the print head to form an image, a media sheet transport for synchronizing movement of a media sheet with rotation of the heated imaging drum, a transfixing roller that forms a transfixing nip with the heated imaging drum to transfix the image on the rotating heated image drum onto the media sheet synchronized by the media sheet transport, and a media director located between the media sheet transport and the heated imaging drum to direct the media sheet into close proximity with the heated imaging drum at a position sufficiently prior to the transfixing nip that the heated imaging drum heats the media sheet before the media sheet enters the transfixing nip.

Abstract: A method of operating a printer turns off a support structure heater when the printer enters standby mode. The print head is then moved away from an intermediate transfer surface supported by a support structure. Heat settings used to heat a print head are then varied to heat the print head and the support structure. Another method of operating a printer turns off a support structure heater when the printer enters standby mode and holds a print head adjacent to an intermediate transfer surface while the printer is in standby mode.
