Abstract: A bladeless impeller and a bladeless axial pump having such an impeller, wherein the impeller has at least one rigid body suitable for rotating around at least one axis of rotation, and at least one helical groove located in the body, forming a passage between two parts of the body.

Abstract: The present invention relates to a centrifugal flow pump that is suitable for pumping blood that can be used as a left ventricular assist device (LVAD). The present invention more specifically relates to a centrifugal blood pump (100) for effectuating conveying of blood in between an axial inlet (22) and a tangential outlet (23), said centrifugal blood pump (100) comprising a pumping chamber housing an impeller (3) attached onto a rotating hub (11) centered on an axis of rotation and a magnetic drive means magnetically coupled to said impeller (3) for rotating impeller (3), and said impeller (3) comprising blades (9, 10) having a geometry that is configured to minimize hemolysis and thrombosis in said centrifugal blood pump (100).

Abstract: A friction force sensing system comprising one interrupter with a blocking extension and one flexible assembly having a fixed end and a free end, longitudinal flexures extending between said fixed end and said free end, said interrupter and said flexible assembly being fixedly connected to each other by a mounting element at the free end of said flexible assembly.

Abstract: A monolithic triaxial dynamometer for machining applications comprising one flexure frame with three flexural arms and three light blocking extensions protruding three different photointerrupter sensors housed in specially designated sensor placement slots situated on the sensor stand, the bottom of which lands on the floor of the external mounting structure, which is aligned and connected with the said top flexure frame using first and third group screw holes, thus bringing together a dynamometer used for force sensing in various industrial applications.
