Abstract: A system and associated method for concentrating and separating components of different densities from fluid containing cells using a centrifuge includes a container defining a cavity for receiving the fluid. The container has a top, a sidewall extending from the top, and a bottom disposed opposite the top and in sealing engagement with the sidewall. An insert is slidably disposed in the cavity of the container and defines a lumen through the insert. The lumen, which includes a hole and a funnel-shaped upper portion in fluid communication with the hole, forms an open fluid path between opposite ends of the insert. The insert has a density such that upon centrifugation a selected component of the fluid resides within the lumen. A container port is disposed in the top of the container to transfer the fluid into the container and to withdraw a fluid component other than the selected component from the container.

Abstract: A reliable and cost-efficient direct drive force feedback motor is suitable for joystick applications, allowing multiple degrees of output freedom, requiring no coil commutation, and permitting compact packaging. A multiple degree-of-freedom motor consistent with the invention comprises an output shaft, a stator, and a rotor. The stator comprises first and second lamination stacks, each lamination stack having an interior curved surface and a coil wound thereon, the lamination stacks being disposed adjacent the output shaft. The rotor is fixed to the output shaft and movably supported adjacent the stator with an air gap disposed between the rotor and the stator, the rotor including at least one magnet disposed thereon and being movable along the interior curved surface of the lamination stacks in directions defining at least first and second degrees of freedom.
