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 universal interface system for use with a data acquisition system including a data acquisition device such as a bar code scanner or scanner integrated terminal for providing digital data signals indicative of acquired data for transmission to a host device such as a computer, and a host device having host-specific input/output data format requirements. The universal interface system comprises universal data exchange means located in the data acquisition device for providing digital data signals in a universal data exchange format independent of the data format requirements of the host device; and a host interface cable coupled to the data acquisition device and to said host device, for transmitting acquired digital data from the data acquisition device to the host device, the interface cable comprising means for translating digital data from the universal data exchange format to the host-specific input/output data format requirements. The interface cable comprises a buffer for storing a host parameter data word used in communications with the host device. The universal data exchange means comprises a memory for storing a plurality of host parameter data words, each of the host parameter data words being associated with one of a plurality of different host interface modules; and means for reading from the memory and transmitting to the host interface module the host parameter data word associated with the particular host interface module operatively connected thereto.

摘要： A system for reading optical codes, and more particularly to code reading systems with sound signal generators, modules a sound detector detects an ambient sound level in a vicinity of the system operator and the volume of the audible indicator is controlled in response to the detected ambient sound level. The sound may be produced by a transducer located in a raised rail adjacent the system operator. Various kinds of audio signals may be produced, for example, to distinguish the system's response from those of nearby optical code reading systems or to identify the kind of optical code symbology being read or its informational content.
