Claim Text:
1. A first pulley assembly for a compound archery bow, the first pulley assembly comprising a draw cable pulley and a power module substantially rigidly attached to the draw cable pulley, wherein: (a) the draw cable pulley is structurally arranged so as to (i) define a first pulley assembly transverse rotation axis, (ii) be mounted on a first limb of an archery bow to rotate about the first pulley assembly axis, (iii) receive a first end of a draw cable of the bow in a circumferential draw cable journal of the draw cable pulley, and (iv) let out the first end of the draw cable when the bow is drawn and the draw cable pulley rotates about the first pulley assembly axis; (b) one or both of the draw cable pulley and the power module are structurally arranged so as to enable substantially rigid attachment of the power module to the draw cable pulley in any one of one or more power module positions and, for each power module position, in any one of two power module orientations; (c) the power module is structurally arranged so as to (i) receive a power cable of the bow in a circumferential power cable journal of the power module, and (ii) take up the power cable when the bow is drawn and the draw cable pulley rotates about the first pulley assembly axis; and (d) each one of the one or more power module positions results in a corresponding draw length of the bow and a corresponding draw weight of the bow; (e) for each one of the one or more power module positions, the two power module orientations result in substantially the same draw length of the bow and substantially the same draw weight of the bow; and (f) for each one of the one or more power module positions, the two power module orientations result in differing stored energies of the drawn bow.
