A centrifuge apparatus is used for collecting white blood cells (WBC), primarily mononuclear cells, from whole blood stratified into layers. A thin mononuclear (MNC) layer is formed at the interface of red blood cells and plasma. A barrier is positioned in the separation vessel of the centrifuge at a location to intercept the thin layer. MNC fluid is allowed to pool behind the barrier before colle...

This invention is a device and method for treating a patent ductus arteriosus in a human. A catheter (20) is provided having a collapsible/expandable heating element (42) at a distal end for entering an infant transcutaneously, and being advanced to the ductus arteriosus (32); and a method of heating the inner surface of the ductus arteriosus (32) with the heating element (42) to a temperature suf...

Loads (17) are displaced by a movable auto-guided vehicle (10) circulating on a guide track (11) near which are provided zones (12,13) for taking and setting down of the loads. The zones are laid out in rows (19) of predetermined spacing and depth on either side the guide rail. A fixed signaller (15), at locations (18) at the inlet to each zone, is connected to a load presence detector (16) in the...

The vehicle controller has detectors delivering in real-time a signal representing the longitudinal speed (CAP1) of the vehicle, and the transverse speed (CAP2) of the vehicle. Actuators control the forward motion (ACT1) and the steering (ACT2) in response to set values. A controller (COMV) receives the remotely set reference values (CREF1,CREF2) for the forward and steering control. The controlle...
