A method and apparatus for locating multiple bar codes in a field. The apparatus includes a microcomputer programmed to detect the existence of bar codes in location cells in the field and then apply a location score to each location cell. Based on the scores assigned to the location cells, a particular location cell is selected and the location cells surrounding the selected cell are analyzed to determine whether they might contain a bar code segment. A location cell that is determined to be sufficiently likely to contain a bar code segment will be appended to the first selected location cell. In this manner, a bar code in the field can be located. The determination of whether the located bar code is a primary or a secondary bar code is made by further analyzing the located bar code. The further analyses may be to determine the located bar code's length, whether it has a predetermined prefix, or whether it has a predetermined pattern of descenders from its constituent line segments. A preferred embodiment of the inventive method and apparatus analyzes the image recorded in the field to locate areas containing Postnet bar codes.

Disclosed is apparatus for scanning a field of view for two-dimensional data and for rapidly processing the data. There is a video device viewing the field of view and producing a two-dimensional matrix of pixel data as an output representing a plurality of pixel positions of the field of view. A digital memory receives and holds the two-dimensional matrix of pixel data output from the video device in a plurality of multiple pixel data words. There is also a digital processor including a register for receiving pixel data and logic for processing data to decode it. Primarily, there is pixelizer logic and associated circuitry connected between the digital memory and the digital processor for removing data associated with a specified pixel position within the field of view from an associated one of the plurality of multiple pixel data words in the digital memory and for placing the data into a pre-established bit position within the register of the digital processor. The time required to repeatedly obtain the necessary pixels for processing is thereby greatly reduced and minimized.

Apparatus is disclosed for automatically determining the volume of an object. The volume system includes a height sensor and a width sensor positioned in generally orthogonal relationship and each constructed to reflect light from a corresponding surface of the object. The height sensor and the width sensor each include a plurality of charge coupled devices for sensing light reflected from the object. The output from the height sensor and the width sensor are provided to a data processor for evaluating the data to determine a plurality of incremental volume of the object as the object is displayed in relation to the height and width sensors. The plurality of incremental volume are then added to determine the volume of the object.
