Abstract: An apparatus for monitoring a power amplifier coupled to a transmission medium includes a detector circuit, coupled to the transmission medium, that generates first and second detector signals corresponding to respective fundamental and harmonic components of a power amplifier output signal produced by the power amplifier. A comparing circuit is coupled to the detector circuit and compares the first and second detector signals. The comparing circuit, responsive to a comparison of the first and second detector signals, may generate a signal that indicates linearity of the power amplifier. In some embodiments, the detector circuit may generate the second detector signal without requiring phase information for the harmonic component. In other embodiments, a control circuit controls linearity of the power amplifier responsive to comparison of the first and second detector signals, for example, by controlling power amplifier bias and/or input signal level based on the comparison. Related methods are also discussed.

Abstract: A system for sorting articles includes a plurality of article supporters attached to an endless chain. At least one diverting point is provided at which the articles may be removed. A plurality of lateral pushers are movable along the article supporter so as to selectively push the articles off the article supporters at the diverting point. A distributing mechanism initiates the movement of the lateral pushers. At least one diversion detection device is configured to identify a presence of each of the article supporters. A controller is configured to determine a slat number of each of the article supporters and to determine whether the article positioned on the article supporter associated with the detected slat number should be removed at the diverting point, and to actuate the distributing mechanism. The at least one diversion detection device is substantially aligned with the actuator in the direction of travel.
