Abstract: Mail can be sorted automatically to point of delivery level by deriving from the address including postal code on a piece of mail a suffix which together with the postal code forms routing data which uniquely identifies the final delivery address. This is achieved automatically at the Post office sorting facility by means of an optical character reader which reads the addresses on mail items and a computer arranged to generate a suffix based on the address read. The routing data is printed as a bar code on the mail item and this allows the complete sortation to be effected automatically. Also contemplated is a progressive encoding system which can be applied as bar codes by customers as desired to mail pieces. The basic data is the routing data set to which can be added a shipment number which allows automatic revenue accounting control and a piece number which allows automatic track and trace.

Abstract: The laser diode of an optical scanning system is located in a separate unit and light therefrom carried to a remote scan head via an optical fiber. This reduces the size and weight as well as temperature sensitivity of the scan head. The separate unit may include an optical sensor for detecting light reflected from scanned symbols. If the separate unit houses the sensor, the same fiber or an additional fiber will collect the reflected light and transmit that light back to the sensor. An electromagnetic system produces a scanning motion of the beam emitted by the scan head where the optical fiber is attached to a magnet.

Abstract: A bar code reader employs plural scanners for scanning a bar code mark with respective, plural optical scanning beams, counters connected with the scanners respectively producing numerical data representing the widths of corresponding black and white bars of the bar code. A composer selects the numerical data from the scanners so as to produce composed numerical data, and a decoder decodes the composed numerical data and produces a bar code data signal output. The composer, upon detecting a false data such as an overflow error data or waveform error data present in the respective numerical data output of a first selected scanner, switches therefrom to the respective numerical data output of a second scanner.

Abstract: A non-contact IC card include a data transmitting/receiving device, a memory, a CPU, a first determining device, a second determining device, and a stopping device. When the data transmitting/receiving device receives a request signal, the first determining device determines whether first system identification information stored in the memory agrees with second system identification information contained in the request signal. At the same time, the second determining device determines whether use of the IC card indicated by use authorization information stored in the memory is authorized. When the first and second system identification information do not agree or when the use authorization information indicates that use of the IC card is not authorized, the stopping device stops the operation of the CPU until the next request signal is received.

Abstract: A system for authorizing access to a secured device, such as an automated teller machine (ATM) or a pay telephone, without a key or combination for the secured device, and without a fixed communication link extending to the device. An encoded access message is produced which identifies a present access code previously stored at the secured device, the personal identification number (PIN) of a technician, and the identification number of a particular portable terminal. The technician manually enters the encoded access message and a PIN into the terminal, which verifies the identification number of the terminal and the manually-entered PIN against information encoded in the access message. If that information is authenticated, the portable terminal is connected to the secured device. The encoded access message is transferred from the terminal to the secured device, which compares an access code previously stored at that device with information contained in the access message. The proper PIN also is re-entered.

Abstract: In order to improve security for holographic labels which are positioned on a substrate base, a bar code symbol is holographically recorded on the base such as a credit card, a label, or a container for a product. A reading apparatus (e.g., a bar code reader) directs light at the holographic bar code symbol and detects the reflected optical information with a detector such as a CCD array. The reading apparatus can be a stand-alone device or, in the case of a credit card, can be incorporated into a conventional swiper for reading magnetic information on a strip on the card. A non-holographic bar code symbol can also be provided on or near a holographic display element, e.g., a rainbow hologram. The bar code can be positioned adjacent the display, or placed in a window within the display, or etched or embossed on the display. A system is also provided for authenticating a holographic display on an information card such as a credit card.

Abstract: After a two-dimensional bar code is scanned to provide a stored image, the location (i.e., bounds, including orientation) of the bar code image within the scanned area image must be determined to enable decoding. Methods for locating the bar code image include the steps of sampling the stored image, identifying sampling traversals of bar code start and stop patterns, and correlating the identified start and stop pattern traversals to a common bar code image. The correlating data is then used to identify a nominally rectangular area bounding the bar code image. A bounding box may be identified as the smallest area capable of encompassing all of the start and stop pattern traversals related to a common bar code image. Output location data may specify the coordinates of the four corners of a bounding box for use in subsequent decoding. Related systems are described.

Abstract: There is disclosed an simplified apparatus that enables optical scanners to achieve minimum field curvature and at the same time provide uniformly distributed light on an image sensor. A single element lens, preferably an aspherical lens made of a plastic material is combined with an aperture stop. The combination is capable of reducing lens aberrations and minimizing image field curvature for an object plane that contains indicia to be scanned or read. A suitably demagnified image of the indicia is focused onto an image sensor such as a CCD array. The spatial light distribution function in the image plane can be equalized by an attenuator, such as a neutral density filter or a slit, suitably configured to compensate for the reduced optical efficiency at large field angles. An aspherical lens containing a dye or a cold mirror can be used for limiting light transmission to a range of wavelengths.

Abstract: An information reader, including a light source for emitting a light beam. A photo-detector detects the light beam after it is reflected from a bar code. A rotatable circular hologram disk scans the light beam in two dimensions and guides the light beam reflected to the photo-detector. A prism deflects the light beam emitted from the light source toward the circular hologram disk. A housing receives the light source, the photo-detector the circular hologram disk and the prism therein. The light source and the prism are integrally detachable from the housing. It is thus easy to adjust the incidence angle of the light beam on the circular hologram disk.

Abstract: A system which utilizes a bar code having an instruction field whose data specifies an action to be performed and also having a reference field whose data relates to the data in the instruction field. The system reads the instruction and reference fields of the bar code and processess the read data. This processing may determine from the instruction field data that the action or actions to be taken are to be taken on data other than that in the reference field of the bar code. It also may determine from the data in the instruction field that an action to be taken on the data in the reference field is other than an action identified in the instruction field of the bar code. Based on these determinations, the system continues the processing using the appropriate action and data.A unique bar is also used in the system. This bar code, between its start and stop fields, has a separator field whose width is greater than that of any of the individual bar code characters.
