Abstract: Briefly, an adapter assembly, such as for use with a bow press that may be utilized to retain a bow, such as a compound bow, may include (among other things) an insert at a first end portion of the bow press for inclusion within an opening of the bow press. The adapter assembly may additionally include an arm that abuts the insert, and may further include an axle and bushing to accommodate a first bracket, the first bracket to exert a compressive force on at least one limb of a bow while the bow is placed between the first bracket and a second bracket at a second end portion opposite the first end portion. The arm may extend in a direction toward the second end portion.

Abstract: An active balancer for dynamically balancing a rotating machine is provided. The active balancer has a balancer body which rotates with the rotating machine and at least one controllable position counter weight having a real-time adjustable position relative to the balancer body and the rotating machine inorder to produce an actively adjustable controllable counter weight balance force for dynamically balancing the rotating machine. The active balancer includes a spring with the balancer body mounted to the rotating machine through the spring wherein the balancer body mass resonates on the spring with a torsional vibration canceling frequency which cancels a torsional vibration of the rotating machine.
