Abstract
An apparatus includes a flywheel, a first pivotable caliper, a first magnet supported by the first caliper opposite the flywheel, a second pivotable caliper and a second magnet supported by the second caliper opposite the flywheel. In one implementation, the apparatus further includes a first cam follower coupled to the first caliper, a second cam follower coupled to the second caliper and at least one cam member including a first cam surface against which the first cam follower moves and a second cam surface against which the second cam follower moves, wherein movement of the at least one cam member pivots the first caliper and the second caliper to move the first magnet and the second magnet relative to the flywheel. In another implementation, the apparatus further includes a strain gauge carried by the first caliper to output signals indicating braking torque.
