摘要:
A method of accessing a remote location on a network using an optical reader. The optical reader has an optical scanning system and a dedicated address memory system. The optical scanning system, in response to the user scanning an encoded indicia therewith, sends to a first computer disposed on the network a scan code indicative of information encoded in the scanned indicia. The dedicated address memory system, in response to the user completing an activation sequence, sends to the first computer a dedicated code indicative of information corresponding to a particular remote location. The information from the dedicated address memory system corresponding to a particular remote location does not originate from the scanning of an encoded indica by the user. One of the scan code and the dedicated code is transmitted from the optical reader to the first computer. In response to the first computer receiving either the scan code or the dedicated code from the optical reader, a second computer disposed on the network is accessed. A lookup operation is performed at the second computer to match the code received from the optical reader, i.e., the scan code or the dedicated code, with a routing information for a remote location on the network. The routing information is returned from the second computer to the first computer. The remote location on the network is then accessed in accordance with the routing information returned from the second computer.

A method of accessing a remote location on a network using an optical reader. The optical reader includes an optical scanning system, a programmable memory system and an output circuit and is user-switchable between a scan mode, a record mode and a playback mode. The optical reader transmits a code to a first computer disposed on the network. When the optical reader is in the scan mode, the code is indicative of information extracted from an encoded indicia just scanned by the optical scanning system. When the optical reader is in the playback mode, the code is indicative of information retrieved from a user-selectable memory in the programmable memory system. The information in the user-selectable memory was previously stored in the user-selectable memory after being extracted from an encoded indicia scanned by the optical scanning system when the reader was in the record mode. In response to the first computer receiving the code from the optical reader, a second computer disposed on the network is accessed. A lookup operation is performed at the second computer to match the code received from the optical reader with a routing information for a remote location on the network. The routing information is returned from the second computer to the first computer. The remote location on the network is then accessed in accordance with the routing information returned from the second computer.

摘要:
A method is provided for transmitting data from an optical reader following scanning by the optical reader of an indica encoding information in accordance with one of a plurality of information encoding types. The method includes determining that a particular one of the plurality of encoding types was used for encoding the scanned indicia. A message packet is then transmitted from the optical reader which is indicative of the particular one of the plurality of encoding types that was used for encoding the scanned indicia.
摘要:
An optical reader for accessing a remote location on a network includes an optical scanning system, a memory system, an output circuit for interfacing to a first computer disposed on the network, and a switching device for switching between a scan mode, a record mode and a playback mode. The optical reader further includes a transmitter for transmitting code information representative of a code to the first computer. In the scan mode, the code information is indicative of information representative of an encoded indicia scanned by the optical scanning system. In the playback mode the code information is indicative of information retrieved from a user-selectable memory in the memory system. The code information is configured to cause the first computer to determine routing information to the remote location, and access the remote location on the network in accordance with the determined routing information.

摘要:
An optical reader is provided for reading a symbol representing information having areas of different light reflectivity. The optical reader comprises a radiant energy source, a photodetector, an optical system and a decoder. The radiant energy source generates a radiant energy for illuminating a target region. The photodetector generates output electrical signals indicative of the radiant energy incident thereon. The optical system includes a projection portion and a collection portion. The projection portion directs the radiant energy along a projection path extending from the radiant energy source to the target region. The collection portion collects the radiant energy reflected from a symbol when the symbol occupies the target region and directs the collected radiant energy along a collection path extending from the target region to the photodetector. The collection portion includes one pinhole aperture disposed upstream on the collection path from the photodetector without intervening refraction or diffraction and one magnifying lens disposed upstream on the collection path from the pinhole aperture without intervening refraction or diffraction. The decoder decodes the output electrical signals of the photodetector to provide indication of the information contained in the symbol.

An optical reader is provided for reading a bar code having ultraviolet-wavelength-responsive properties. The optical reader includes an ultraviolet light source, a photodetector, an optical system and a decoder. The ultraviolet light source generates ultraviolet light having a wavelength shorter than visible light and longer than X-rays for illuminating a target region. The photodetector generates output electrical signals indicative of light incident thereon having a wavelength within a predetermined range of wavelengths. The optical system includes a projection portion and a collection portion. The projection portion directs the ultraviolet light along a projection path extending from the ultraviolet light source to the target region. The collection portion collects the light from a bar code when the bar code occupies the target region and directs the collected light along a collection path extending from the target region to the photodetector. The decoder receives the output electrical signals of the photodetector and produces, in response thereto, electrical signals indicative of information encoded in the bar code.
