Abstract: An electronic cutting machine includes at least one housing to which a drive roller is coupled for moving a sheet to be cut in a first direction and a cutter assembly coupled to the housing and moveable in a second direction that is perpendicular to the first direction.

Abstract: A system for printing and cutting including a housing. A printing system is connected to the housing. The printing system including a print head having a bottom surface. A cutting system is connected to said housing. A movable floor is connected to said housing where the movable floor adjusts to the thickness of a stock to be printed. The movable floor providing a predetermined distance from the bottom surface of the print head and the upper surface of the stock.

Abstract: A pump for pumping sensitive fluids, such as blood, has no mechanical contact between the impeller and any other structure.

Abstract: A ventricle assist device for placement within a living body and including a self contained drive motor for generating pumping action with respect to a hydraulic pumping fluid. The ventricle assist device includes a ventricle having a blood chamber and a pumping chamber and an interconnect means coupled to the pumping chamber of the ventricle for receiving and displacing hydraulic fluid. A separate volume displacement chamber is attached to the interconnect means and provides a reservoir for excess hydraulic fluid for storage during diastole. A fluid pump and drive motor is positioned within the volume displacement chamber and connected at the interconnect means to supply the required pumping action for transfer of hydraulic fluid to and from the pumping chamber. Placement of the fluid pump and drive motor within the volume displacement chamber provides enhanced dissipation of heat from the energy conversion system and improved performance and durability.

Abstract: An artificial heart device for producing heart pumping action as part of a total artificial heart implant comprising a semi-rigid housing of approximate ellipsoidal configuration which encloses a pumping volume divided into a blood chamber and a pumping chamber by a deformable diaphragm structure which is symmetrically positioned about a short axis of the ellipsoid housing. This diaphragm structure is also configured as a hemiellipsoidal structure, allowing the device to have smaller dimensions but to maintain the required high stroke volume necessary to function within a human circulatory system. The device includes valved inlet and outlet openings coupled through the housing and in communication with the blood chamber. A pneumatic pump is coupled to the pumping chamber through a series of concentric vents formed within the base of the artificial heart device.
