  • LOW PROFILE PROSTHETIC FOOT
    Publication number: 20070027557
    Abstract: A low profile prosthetic foot comprises a foot member extending at an incline from an anterior portion to a posterior portion thereof and configured to flex during motion, and an adapter mounted solely at a posterior section thereof to the posterior portion of the foot member so that the adapter's anterior section can move relative to the foot member and “roll-up” onto the foot member during motion.
    Type: Application

  • Methods and apparatus for optimizing shell mapping techniques using an approximated power cost function
    Patent number: 6259742
    Abstract: To compensate for the substantially non-uniform spacing of constellation points in a pulse code modulation modem, the transmitting power efficiency is substantially maximized while substantially limiting the complexity of the mapping. To optimize the transmitting power efficiency, the present invention suitably determines an approximate cost function g(n) to reduce the complexity and the 2K lowest cost N-tuples (m0,m1, . . . ,mN-1) for power transmission efficiency. Knowing the lowest cost N-tuples, fractional K data bits are systematically mapped uniformly onto the 2K lowest cost N-tuples.
