Abstract: A garment having a piece of clothing with a plurality of pad segments located proximate a backside of a wearer's body, including at least one joint region, for protecting the wearer by dissipating energy resulting from a sudden impact. The pad segments arranged with respect to the interior radius of the joint region such that an interstitial space located between each adjacent pad segment becomes narrower moving a protruding portion of each adjacent pad segment closer together, and in some instances such that the adjacent protruding portions touch one another, when the joint region moves from an extended position to a flexed position. The garment with energy dissipating pad segments may be used alone or in conjunction with pads that shield energy.

Abstract: Image rejection calibration includes initializing the calibration mode by applying to quadrature mixers, in place of the wanted RF input, an RF source in the frequency range of the wanted RF input, sensing the power output from the poly-phase filter, developing gain adjust and phase adjust correction values in response to the power output and adjusting in accordance with the correction values the gain of the quadrature signals from the quadrature mixers to the poly-phase filter and the phase of local oscillator quadrature signals from the local oscillator to the quadrature mixers to reduce the power output.
