US Patent 7703449 Limb dampeners

Disclosed is a device made of a soft, flexible elastomer with freely movable members for use as a vibration dampener on an archery bow limb. Upon release of an arrow from an archery bow, the damper members reactively contact and rebound against the bow limb. The device can be installed on a mount to attach to both solid limb and split limb bows at the same general location on both the top and bottom limbs to greatly reduce the duration of vibration, the amount of hand shock and perceived noise generated upon release of an arrow from an archery bow.
