Abstract
A stand is provided for mounting various loads and is balanced at least partially automatically. The stand includes a plurality of interconnected elements defining one or more axes about which the stand is movable. An open-loop or closed-loop control circuit is provided for at least one of the axes and detects the unbalanced state about the one axis. The control circuit allows a torque compensating device to operate on the one axis until a state of equilibrium is obtained.
Claims32
A stand for mounting a diagnostic and/or therapeutic device defining a load, the stand comprising:
- a base;
- a plurality of interconnected elements mounted on said base and defining at least one axis about which said elements are movable relative to said base;
- a balancing sensor assigned to said axis for detecting an unbalanced state relative to said axis and for supplying a sensor output signal indicative of said unbalanced state;
- a motor-driven torque compensator for acting on said axis;
- and,
- a balancing control circuit for acting on said motor-driven torque compensator in response to said sensor output signal until a state of equilibrium is obtained about said axis.
A stand for mounting a diagnostic and/or therapeutic device defining a load, the stand comprising:
- a base;
- a plurality of interconnected elements mounted on said base and defining a plurality of axes about which said elements are movable relative to said base;
- a plurality of balancing sensors assigned to corresponding ones of said axes for detecting respective unbalanced states relative to said axes, respectively, and for supplying corresponding sensor output signals indicative of said unbalanced states, respectively;
- a plurality of motor-driven torque compensators for acting on corresponding ones of said axes;
- a plurality of balancing control circuits for acting on corresponding one of said motor-driven torque compensators in response to said sensor output signals, respectively, until corresponding states of equilibrium are obtained about said axes, respectively.
An X-Y displacing device for a stand for mounting a diagnostic and/or therapeutic device defining a load, the stand including a base, a plurality of interconnected elements mounted on said base and defining one or more axes about which the elements are movable relative to said base, the X-Y displacing device being arranged between the stand and said load for displacing said load in the X-Y plane defining a X-direction and a Y-direction, the X-Y displacing device comprising:
- a motor for positioning said load in said X-Y plane;
- at least one balancing sensor for detecting the load forces applied to said X-Y displacing device in at least one of said X-direction and said Y-direction;
- and,
- a balancing control circuit for acting on said motor in response to the output of said sensor until said load is balanced in said X-Y plane.
A method of balancing a stand for mounting a diagnostic and/or therapeutic device defining a load wherein the balancing is at least partially automated, the stand including a base, a plurality of interconnected elements mounted on said base and defining one or more axes about which the elements are movable relative to said base, the method comprising the steps of:
- detecting an unbalanced state of at least one of said axes utilizing a balancing sensor;
- and,
- providing a closed-loop balancing control circuit for at least one of said axes for acting on a motor-driven torque compensator until said axis reaches a state of equilibrium.
A method of balancing a stand for mounting a diagnostic and/or therapeutic device defining a load wherein the balancing is at least partially automated, the stand including a base, a plurality of interconnected elements mounted on said base and defining one or more axes about which the elements are movable relative to said base, the method comprising the steps of:
- detecting an unbalanced state of at least one of said axes utilizing a balancing sensor;
- determining a required actuating variable for a motor-driven torque compensator;
- and,
- providing an open-loop control circuit for at least one of said axes and allowing said actuating variable to act on said motor-driven torque compensator for said one axis.
