Abstract: A method for reading a digital graphical diagram representing an electric circuit is provided. The graphical diagram includes one or more diagram pages, each representing a portion of the electric circuit. The method includes for each diagram page detecting the graphical objects included in the diagram page, for each diagram page basing on the detected graphical objects, obtaining predictive information related to the components included in the portion of electric circuit represented in the diagram page, and for each diagram page harmonizing the predictive information related to the components of the portion of electric circuit represented in the diagram page to obtain an identification list of the components of the electric circuit.

Abstract: A device (10) for assisted omnidirectional movement of hospital beds (12) and other omnidirectionally mobile loads, comprising: an L-shaped base structure (40); a first motor-driven steering wheel (41) set along a first arm of said L-shaped base structure (40); a second motor-driven steering wheel (42) set along a second arm of said L-shaped base structure (40); a third wheel (43) set in the corner point of said L-shaped base structure (40); said base structure (40) comprises means (30, 35) for engagement to said hospital beds (12) and other omnidirectionally mobile loads; and control means (50) to cause rotation and orientation said first motor-driven steering wheel (41) and said second motor-driven steering wheel (42); where said hospital beds (12) and other mobile loads comprise wheels (14), and the weight of said hospital beds (12) and other mobile loads is sustained only by said wheels (14).
