Any number of transceiver channels is tested for jitter generationtolerance simultaneously. The system instructs the display device to render a pattern; determines the output quality of the second scaler; and compares the quality of the second scaler with the predetermined output quality and selects the scaler with higher quality. The method further involves using an inference engine to allow data collection at any time and in any order via specific, personalized questions geared toward completion of the tax return. Spiral scanning patterns without turnaround regions are utilized in embodiments of the present invention, both with and without rounded corners in the scanning patterns. Pushers 9 act upon the objects in such a way as to move the objects into the cartons as the cartons and objects are moved along synchronously on the conveyors.
