摘要:
A wavelength selector in an optical scanner is operative for selecting a first laser beam having a predetermined wavelength to produce a first scan pattern, and for selecting a second laser beam having a different wavelength to produce a second scan pattern. The scan patterns have a different number of scan lines. The selected scan pattern is scanned over indicia, e.g., a bar code symbol, to be read.

A wireless local area network for digital radio communication between remote devices and a PBX telephone system, wherein the remote devices can access and use the voice message features in the PBX and the data bases on a host computer and servers. A wireless phone is provided for voice and data communication through the PBX or a CO telephone line with remote locations or the Internet using digital data packets and standard Internet Protocol. In a preferred embodiment of the invention, the remote device is a cash register comprising a bar code scanner and a phone. Radio communication between the register and a host computer is carried out over two channels, a first channel for data communication and a second channel for voice communication.

A portable tendering station includes a movable housing, a removable terminal attached to the housing for acquiring transaction information, and at least one peripheral device attached to the housing and coupled to the terminal for conveying the transaction information and related information to or from a user. Preferably, the terminal includes a display and a device for communicating the information over a wireless communication network, and at least one activation key for activating one or more user functions. The portable tendering station can be easily deployed to various locations within a shopping facility, warehouse, manufacturing facility or the like, and is especially useful for accommodating customers and minimizing delays during peak activity periods.
摘要:
A system for reading and writing indicia on a medium including a light source for producing a light beam; a reading element for directing the light beam at the medium so as to scan indicia disposed on a first portion of said medium, detecting at least a portion of the light of variable intensity reflected off the indicia, and generating an electrical signal indicative of the detected light intensity; and a writing element for directing the light beam at the medium in a pattern on a second portion of the medium so as record information on the medium. The light beam is preferably a laser beam generated by a semiconductor laser, and a mirror is used to scan the beam both for reading and writing.

A data terminal includes a digital camera for capturing an image and data processing/storage/encoding means for processing the image information, together with an internal server for creating a web site at the terminal displaying the image. As a result high resolution image information is immediately accessible to authorized users and instantly recorded.
摘要:
A system for transferring data between a centrally located site and a portable communications terminal via a telephone network, the site having associated therewith a look up table containing-plurality of data records correlating to items disposed at a retail establishment, wherein each of the items has associated therewith a bar code encoded with the indicia unique to each item, with each of the bar coded indicia corresponding to a particular record in the table, the data containing at least a portion of said record.
摘要:
A data system and method for retrieving information from a particular address of a computer network using a collection of bar code symbols and a hand-held, portable terminal. Each of the bar code symbols of the collection includes encoded data that is associated with a particular computer network address. The hand-held, portable terminal comprises a reading unit including a laser scanner or a CCD array, a communications unit, and a display. In operation, the reading unit scans or images a bar code symbol from the collection, the communications unit establishes a connection to the computer network and accesses the computer network address associated with a particular bar code symbol, and information stored on the computer network at a location associated with the network address is transferred to the terminal and displayed on the display.

摘要:
An apparatus for reading indicia having parts of different light reflectivity includes a keyboard for inputting data, a monitor for housing a display, and a reader for reading said indicia, wherein said reader is retractably integrated into either said keyboard, monitor, or a point-of-sale terminal. The apparatus has a particular application in reading barcode symbols in instances where there is a need to save space or where there is a need to avoid the cost of purchasing a separate reader component.
摘要:
A wireless system for self-service shopping is described that includes a customer identification device with an optically readable code, a portable terminal that includes an optical code reader, a local area radio, a terminal controller, and a locking mechanism, a master station, consisting of a master controller and a master radio, and a receiving rack for the portable terminals to which the scanners may be locked using the locking mechanism. A customer presents his or her identification device to a terminal which reads the code, the code is transferred by radio to the master controller which checks the identification and, if valid, sends an authorized signal by radio to the terminal to unlock the scanner. In addition, several locking mechanisms are described that are controlled by the terminal controller. An additional feature provides a shopping cart with a receiving cradle for a portable terminal that allows the customer to lock the scanner onto the cart for hands-free shopping.
