The invention provides a method, apparatus and system for separating blood and other types of cellular components, and can be combined with holographic optical trapping manipulation or other forms of optical tweezing. One of the exemplary methods includes providing a first flow having a plurality of blood components; providing a second flow; contacting the first flow with the second flow to provide a first separation region; and differentially sedimenting a first blood cellular component of the plurality of blood components into the second flow while concurrently maintaining a second blood cellular component of the plurality of blood components in the first flow. The second flow having the first blood cellular component is then differentially removed from the first flow having the second blood cellular component. Holographic optical traps may also be utilized in conjunction with the various flows to move selected components from one flow to another, as part of or in addition to a separation stage.

The present invention relates to an agricultural coupling with a system for managing and guiding maneuvers and a method implemented by this coupling. A coupling comprising a tractor and at least one agricultural machine coupled by at least one articulated linkage, said coupling also comprising a maneuver management and guidance system comprising at least one calculation and control unit. A coupling characterized in that the calculation and control unit of the one of the coupled agricultural machine constitutes the master unit of system for managing and guiding maneuvers and preferably for coupling, and in that it is suitable and intended, under the control of a suitable maneuvering management program: on the one hand, to calculate a setpoint trajectory For at least one future maneuver, by implementing a trajectory prediction algorithm and a path optimization algorithm and, on the other hand, to automatically execute said maneuver or to assist in a semi-automatic execution of said movement Maneuvering by driving the tractor and raising, during maneuvering, the deviations between the predefined setpoint path and the actual or currently estimated trajectory.

The sectional door (1) for the control of the access opening to a compartment, particularly to a garage compartment, comprises: - a fixed portion including two pairs of vertical guides (5, 6) suitable for extending in a direction substantially parallel to a respective shoulder of the access opening to a compartment; and a movable portion including: a leaf comprising a lower panel (7) and an upper surrounding panel (8), substantially rectangular in shape, extending over the entire width of the leaf and having the lateral sides thereof in sliding engagement along a respective side guide (5, 6); a pair of side support arms (11) each having one end thereof articulated in correspondence to the top of a respective pair of vertical guides (5, 6) and the other end thereof pivoted in correspondence to an intermediate zone (8c) of a respective lateral side of the upper panel (8); and articulated and slidable connection means (12) between the lower panel (7) and the upper panel (8), including a pair of lateral sliding guides (10) provided in correspondence to the lateral sides of the upper panel (8), and a pair of connection levers (13), each having one end (15) thereof in sliding engagement with a respective lateral sliding guide (10) of the upper panel (8) and a second end (14) thereof articulated at the top to the lower panel (7), whereby the lower panel (7) and upper panel (8) are movable between a completely closed position of the access opening, in which they are arranged in a substantially aligned sequence, one on top of the other, along the pairs of vertical guides (5, 6), and a completely open position, in which the upper panel (8) is overhangingly moved to project in the compartment starting from a zone in correspondence to the top of the pairs of vertical guides (5, 6), supported by the pair of side support arms (11) and the lower panel (7) is moved together with, and against the upper panel (8).
