Abstract: A method is presented comprising analyzing two or more input terms on a per-bit basis within each level of bit-significance. Maximally segmenting each of the levels of bit-significance into one or more one-, two-, and/or three-bit groups, and designing a hyperpipelined hybrid Wallace tree adder utilizing one or more full-adders, half-adders, and associated register based, at least in part, on the maximal segmentation of the input terms.

Abstract: A handheld computing device is introduced comprising a motion detection sensor(s) and a motion control agent. The motion detection sensor(s) detect motion of the computing device in one or more of six (6) fields of motion and generate an indication of such motion. The motion control agent, responsive to the indications of motion received from the motion sensors, generate control signals to modify one or more of the operating state and/or the displayed content of the computing device based, at least in part, on the received indications.

Abstract: A method and apparatus for calibrating antenna array systems comprising of a portable transponder (118) and a calibration processor (124). Calibration processor (124) generates calibration transmit signals which it transmits using transmit signal processor (104) and antenna array (111). Transponder (118) echoes these signals back and they are acquired by calibration processor (124) through antenna array (111) and receive signal processor (106). Calibration processor (124) processes the received signals to calculate antenna calibration vector (102).
