    摘要: The present invention relates to a personal shopping system for combined use in both the home of a user and a shopping establishment. The system includes a host computer which is coupled to a host modem and, optionally, to at least one wireless multi-access point. The portable terminal can be used in both the shopping establishment and the home of the user. It is configured to read bar codes associated with items related to shopping, and includes a memory, a bar code reader, a wireless transceiver, and a data interface. The data interface of the terminal communicates with a data interface of the shopping establishment kiosk cradle or directly with the shopping establishment's communications network.

    摘要: In a system for electro-optically reading bar code symbols, a movable reflector is rearwardly positioned in a hand-held housing. A sensor receives light reflected off a bar code symbol from the reflector over a scan that extends across the entire bar code symbol. The housing has a window, a front end and a handle for enabling a user to hold and support the housing in one's hand, and to aim the front end of the housing at the bar code symbol during reading. A signal processor in the housing processes an electrical signal from the sensor to generate therefrom data descriptive of the bar code symbol being read. The reflector is positioned at a distance from the front end of the housing, and the length of the scan is proportional to that distance.

    摘要: A microprocessor-controlled device with software files stored in non-volatile memory which can be easily modified by the user by reading or scanning a two-dimensional bar code symbol having program modification information encoded thereon. The symbol can be read by two-dimensional or one-dimensional laser or CCD based means. Depending on its size, either the entire file can be replaced, selected locations can be replaced, or selected relocatable object files can be linked at the target device in order to effect the program revision.
