An apparatus and method for calibrating a barcode scanning tunnel has a conveyor structure and a scanning system. The scanning system has a laser light source, an optics system, and a processor. In a calibration mode, the processor locates a central area of the conveyor structure and identifies a first location at which there is a height above the level of the central area according to a predetermined criteria. The processor identifies a second location that is offset, by a predetermined distance in a direction transverse to the direction of travel of the conveyor structure, from the first location.

Dimensioning and barcode reading system

An antenna selection method is used in a wireless location system that determines the geographic location of a mobile wireless transmitter. The wireless location system includes signal collection systems connected to multiple antennas at a plurality of cell sites and a location processor for processing digital data provided by the signal collection systems. The antenna selection method comprises evaluating segments of data collected from a plurality of antennas at a signal collection system, selecting a subset of the segments of data, and using only the selected segments of data in location processing.

Antenna selection method for a wireless location system

A Wireless Location System includes signal collection systems and location processors for processing digital data provided by the signal collection systems. To determine the geographic location of a mobile wireless transmitter, time difference of arrival, or TDOA, data is determined with respect to a plurality of first signal collection system/antenna second signal collection system/antenna baselines. A method for selecting baselines for use in location processing comprises calculating a number of parameters for each of the plurality of baselines, and including in a final location solution only those baselines meeting or exceeding predefined threshold criteria for each of the parameters.
