Abstract: A portable hand-held device (10) for data collection by an operator includes a grip unit (12) having polarized connectors (31, 32) at the top and bottom thereof for removable engagement with mating polarized connectors (33, 34) in external modulus (14) furnishing operator selectable, application functions such as CCD or laser scanning, and radio frequency automatic identification. Device (10) is held and operable by one hand in either right- or left-handed configurations with the output from modules (14) directed away from the operator and toward the object from which data is to be obtained. The connectors (31, 32) are mounted in reversed orientation from each other, thereby insuring that external removable modules (14) are automatically connected in the proper orientation for the desired handed operation.

Abstract: Various embodiments are directed to a non-linear amplifier system comprising a reference output generator, an adaptive filter, a amplitude distortion (AM-AM) compensator, a phase distortion (AM-PM) compensator, an adaptive spectrum controller and a non-linear system. The reference output generator may receive an input signal and generating a reference output. The adaptive filter may generate a modified input signal based on the input signal and the reference output. The AM-AM compensator may act on the modified input signal to compensate for AM-AM distortion. The phase distortion (AM-PM) compensator may act on the modified input signal to compensate for AM-PM distortion. The adaptive spectrum controller may provide parameters to the adaptive filter to minimize the power spectral density (PSD) of an output of the non-linear amplifier system in a stop-band and maximize the PSD of the output of the non-linear amplifier system in a pass-band.
