A liquid circulation device includes a housing having an outlet and an inlet, a circulation unit configured to convey liquid out of the housing through the outlet and recover liquid into the housing through the inlet, a liquid supplying unit configured to supply liquid into the housing, an air conveying unit configured to convey air into and out of the housing, a level detecting unit configured to detect a level of the liquid in the housing, a pressure sensing unit configured to detect a pressure of the air in the housing, and a control unit configured to control a pressure of the liquid in the housing by controlling the liquid supplying unit or the air conveying unit, based on the level and the pressure of the air.

An apparatus detects movement of a target object, estimates a control quantity for first feedback control for the target object at a first period, based on a detection signal, and estimates a first state quantity of the target object and a second state quantity obtained by time differentiation of the first state quantity in order to perform second feedback control for the target object at a second period shorter than the first period, based on the detection signal. The apparatus generates a first operation quantity for the first feedback control, based on the estimated control quantity, generates a second operation quantity for the second feedback control, based on the estimated first and second state quantities, and determines an output value, based on a result of comparing the second operation quantity with a maximum value of the first operation quantity.

A printing platform includes a printing engine with one or more printheads arranged such that the ink drops are jetted vertically upwards against the action of gravity; and a substrate transportation system where the normal to the surface in contact with the substrate is parallel and with opposite direction to the travelling direction of the jetted ink drops. It is necessary to counteract the weight of the substrate during the printing process to avoid it from falling under the action of gravity. This is achieved through any of a mechanical element that interferes with the falling of the substrate and that keeps it in place; or a system that generates adhesion forces between the element that transmits the motion to the substrate, typically a conveyor belt, and the substrate through the action of electrostatic forces, an air pressure differential between both faces of the substrate, or any other suitable mechanism.
