Abstract
Abstract An optical information handling system including an encoded information carrier in which information is represented by marks which transmit one of a plurality of optical wave length signals, the marks being arranged in quadricode form, and a reading and decoding network for receiving the optical wave length signals from the marks, translating the signals into a modified binary representation and decoding the modified binary representation into a true binary output.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
158 words
An optical information system, comprising: encoded means bearing information in the form of indicia each transmitting a signal in one of a plurality of optical wavelength bands, the indicia being received selectively in a plurality of predetermined places for each alphabetical or numeric information bit so that the base of code is determined by the number of bands or colors plus one, means for receiving optical signals including a plurality of optical receivers each associated with a predetermined place on said encoded means for reading the indicium in that place, means for determining within which wavelength band the signal from each receiver falls including a determining circuit associated with each receiver, each of said determining circuits having a plurality of channels equal in number to the number of predetermined wavelength bands, means providing one output signal from each of the determining circuits, and means combining the output signals of the determining circuits associated with the same information bit.
Claim 2
Dependent Claim
158 words
An optical information system, comprising: encoded means bearing information in the form of indicia each transmitting a signal in one of a plurality of optical wavelength bands, the indicia being received selectively in a plurality of predetermined places for each alphabetical or numeric information bit so that the base of code is determined by the number of bands or colors plus one, means for receiving optical signals including a plurality of optical receivers each associated with a predetermined place on said encoded means for reading the indicium in that place, means for determining within which wavelength band the signal from each receiver falls including a determining circuit associated with each receiver, each of said determining circuits having a plurality of channels equal in number to the number of predetermined wavelength bands, means providing one output signal from each of the determining circuits, and means combining the output signals of the determining circuits associated with the same information bit.
Claim 3
Dependent Claim
31 words
An optical information system as defined in claim 1, and decoder means connected to receive the output signals from the determining circuits and convert them to a time binary output representation.
Claim 4
Dependent Claim
241 words
An optical information system and an encoded card providing a representation of information in two forms, comprising: card means for receiving information, a plurality of information areas on said card means, each of said information areas including at least two predetermined positions for receiving indicia, each information bit being represented by the presence or absence of indicia in at least two positions, indicia selectively placed in said positions to represent the desired information, said indicia each adapted to transmit an optical wavelength within one of a plurality of optical wavelength bands so that the information may be read optically, the indicium in one of the positions being in the form of alphabetical or numerical representations of the same information so that the information may be read visually; means for receiving optical signals including a plurality of optical receivers each associated with a predetermined place on said encoded means for reading the indicium in that place, means for determining within which wavelength band the signal from each receiver falls including a determining circuit associated with each receiver, each of said determining circuits having a plurality of channels equal in number to the number of predetermined wavelength bands, each of said channels determining whether the signal from the receiver falls within one of the wavelength bands, means providing one output signal from each of the determining circuits; and means combining the output signals of the determining circuits associated with the same information bit.
Claim 5
