摘要:
A microprocessor controlled DC power supply and a method for controlling a first and a second electric motor. The invention relates to a method for controlling a first and a second electric motor by means of a microprocessor controlling the power supply to said first motor and said second motor. The method involves the steps of: Monitoring the rotational angles of the outputs of said first motor and said second motor. Disabling the current supply to that motor when one of said first motor or said second motor reaches said predetermined angle. Enabling the current supply to said one of said first motor and said second motor again when the other of said first motor and second motor reaches said predetermined angle. The invention also relates to a power supply for executing the method.

A DC/DC power supply comprising a transformer. The transformer has a primary winding with a first end and a second end and two secondary windings. Switching means are arranged in connection with said primary winding, and a diode is arranged in series with each of said secondary windings. The power supply comprises a voltage divider with a centre tab, to which said first end of said primary winding is connected. The second end of said primary winding is connectable to either side of said voltage divider via said switching means.

The hinge device for joining two objects in an articulated, springloaded manner comprises a first threaded rod, a first threaded tube and a spring element. The threaded rod has an outer thread corresponding to an inner thread of the threaded tube, the threaded rod and the threaded tube being movable axially in relation to each other by means of the corresponding threads. One of said threaded rod and said threaded tube is attachable to the first object such that it, in use, is retained against movement in its axial direction with respect to said first object and is able to rotate about its axis with respect to the other of said threaded rod and said threaded tube. The other of said threaded rod and said threaded tube is connectable to a second of said objects such that it, in use, is movable in its axial direction with respect to said first object and is retained against rotation about its axis with respect to said second object. The spring element is provided such that, in use, said axial movement of said other of said threaded rod and said threaded tube in said corresponding threads provides a spring force exerted by said first object on said second object.
