Abstract
An eddy-current braking mechanism including a rotor, rotatable about a rotor axis; at least one electrically conductive member coupled to the rotor for rotation therewith; at least one magnet configured to apply a magnetic field extending at least partially orthogonal to the plane of rotation of the conductive member, and characterised in that upon rotation of the rotor, the conductive member is configured to move at least partially radially from the rotor axis into the applied magnetic field.

An eddy-current braking mechanism comprising:
- a rotor, rotatable about a rotor axis;
- at least one electrically conductive member coupled to the rotor for rotation therewith;
- at least one magnet configured to apply a magnetic field extending at least partially orthogonal to a plane of rotation of the at least one electrically conductive member;
- and

A line dispensing device comprising:
- a braking mechanism comprising:
- a rotor rotatable about a rotor axis;
- at least one electrically conductive member coupled to the rotor for rotation therewith;
- at least one magnet configured to apply a magnetic field extending at least partially orthogonal to the plane of rotation of the conductive member;
- and
- a spool of line;
- wherein upon rotation of the rotor, the at least one electrically conductive member is configured to move at least partially radially from the rotor axis into the applied magnetic field, and the spool of line is coupled to the rotor and/or at least one electrically conductive member for rotation therewith.
(canceled)
A method of braking rotation of an object, the method comprising the steps of:
- i) providing at least one magnet configured to apply a magnetic field extending at least partially orthogonal to the plane of rotation of a rotatable conductive member;
- ii) coupling the conductive member to the object for rotation therewith about a rotor axis;
- and
- iii) configuring the conductive member to move at least partially radially from the rotor axis into the magnetic field upon rotation of an object.
