    摘要： A electro-optical memory includes a substrate on which is printed (or otherwise inscribed) a complex symbol or "label" or "bar code" of a high density two-dimensional symbology. The bar code contains component symbols or "codewords" which are placed in row and column formation, with a variable number of codewords per row, and a variable number of rows. The symbology utilizes implicit bar code encoding scheme for implicit encoding the number of rows and the number of columns of codewords, as well as a predetermined amount of error correction. The symbology is capable of supporting a fixed number of bar code variants, with each variant having a predetermined number of rows and columns of codewords, and a predetermined error correction capability. For some codewords the implicit encoding scheme is combined with a gray coding scheme to reduce the inter-row codeword crosstalk. Systems are used for printing and decoding the bar codes of the invented symbology in applications where improved storage density and tight real estate requirements are of utmost importance. A memory may be used in conjunction with a scanner and a suitable control system in a number of applications, e.g., robotics operations or automated object searching.

    摘要： A data encoding/decoding scheme includes a plurality of bar code symbols each carrying a portion of the data in which improved error correction capabilities are incorporated. According to one aspect, once data codewords have been derived to form the symbols, a first set of data correction elements are derived from a first field, then a second set of error correction elements are derived from the data elements and the first set of error correction elements using a second, wider field.

    摘要： In exemplary embodiments, an apparatus and method for providing pricing options in a consultation system is provided. In one embodiment, user input from a user is received. The user input is directed to a question the user intends to post to the consultation system. Pricing factors are determined in part from the user input. A pricing option is then determined by analyzing the pricing factors with pricing attribute data whereby the pricing attribute data may be based on current consultation system dynamics, user history, and completed transactions on the consultation system. The determined pricing option is presented.

    摘要： A method of reading bar code symbols includes determining one or more parameters based upon the quantity and/or quality of the data which is being acquired, and providing the user with information concerning that parameter. The parameter may, for example, be the rate at which code words in the symbol are being read, and that information may be passed to the user by way of an LED which flashes at a rate which varies with the data acquisition rate. For a given bar code symbol being read, the rate of flashing varies with the position of the bar code reader with respect to the symbol. To improve the data acquisition rate, the user simply moves and/or rotates the bar code reader with respect to the symbol in a direction which causes the rate of flashing to increase. The invention extends to a bar code reader having means for providing an indication to a user of the relative suitability, for optimal reading of a symbol, of the current position of the reader.

    摘要： A method and apparatus for increasing the information density of a bar code symbol by generating multiple constituent bar code symbols, wherein each one is formed in a different color selected from a group of various primary colors, and overlaying each differently colored symbol on top of each other, thus forming an aggregate bar code symbol of various colors. In areas where the differently colored bars overlap each other, colors distinct from those in the original group of colors are formed. The aggregate bar code symbol is scanned by a solid state imaging device, and the scanned image is resolved by image processing techniques into the three constituent bar code symbols of the various colors. Each bar code symbol is then individually processed and decoded in accordance with the particular symbology used to encode the constituent bar code symbols. As a result of the present invention, multiple bar code symbols are printed in the space normally required by one bar code symbol, and each constituent symbol is separated by color resolution and decoded to form the original data. Thus, the information density of the bar code system is increased without the need for a new symbology. In addition, a single bar code symbol may be divided into multiple portions of substantially the same size and printed substantially over each other in different colors, thus producing a single compacted bar code symbol with increased information density. The compacted bar code symbol may be recovered by scanning and resolving the symbol back into its constituent portions, concatenating the portions together, and decoding the resulting bar code symbol in accordance with standard techniques.
