  • Patent number: 6564995
    Abstract: A multi-application smart card has a persistent storage unit. The persistent storage unit stores data and/or information that indicates which application is to be run the next time the smart card is inserted into a terminal. The persistent storage unit may indicate the same application, a different user-selected application, or an application-selection application is to be run next. Alternatively, the persistent storage unit may indicate the next application on a predefined list as the application to be run next. An application-selection terminal allows a user to manually select the user-selected application. The terminal may initiate communication with the smart card by sending a special, predefined signal to the smart card.

  • Patent number: 6543693
    Abstract: A scanning device incorporates a vertical cavity surface emitting laser (VCSEL). The laser diode may be mounted directly on an Si substrate which is adapted for movement to produce a scan pattern. A collimating lens may be directly mounted on the emitting surface of the laser. A plurality of lasers may be mounted on the substrate and operated in sequence without movement of the substrate to produce the effect of a scan. A single, variable-focal length lens is employed to focus each beam of the VCSEL at a different distance. The scanning device emits visible or invisible light towards a target such as a bar code and a detector (mounted on the same or an adjacent substrate) senses the light reflected by the target to produce data which is decoded for further processing. A VCSEL uses low current and emits light from a relatively large area so that a relatively large amount of light is emitted for relatively small heat generation.

  • Patent number: 6540144
    Abstract: A bar code scanner is equipped with a keyboard emulation mechanism so as to provide an enhanced interface to a keyboard controller port of a computing device such as a personal or laptop computer. The keyboard emulation mechanism eliminates the necessity of connecting an actual computer keyboard to the port by responding to the computing device's standard power-on diagnostic procedure as if it were effectively an electrical equivalent of a computer keyboard. The keyboard emulation mechanism can also be equipped to detect a keyboard inhibit signal at the keyboard controller port. If the keyboard emulation mechanism detects a keyboard inhibit signal while a data byte is being transmitted to the keyboard controller port, the keyboard emulation mechanism retransmits this data byte to the keyboard controller port. The data byte may specify a scan code corresponding to a keyboard key press or all or part of a decoded bar code.

  • Patent number: 6536666
    Abstract: The intermingling of bar code data and typed-in data in a keyboard-wedge configuration is prevented through the use of a message-based keyboard inhibit procedure implemented by the bar code scanner. In this manner, both the typed-in data and the bar code data will remain uncorrupted, even if the keyboard data is being entered substantially simultaneously with the scanning and/or decoding of bar code data. This message-based keyboard inhibit procedure tests for any communication in progress between the keyboard and PC. If no communication is in progress, the bar code scanner places a switching mechanism into a first state so as to disable communications between the keyboard and a keyboard controller port of a PC (personal computer), thereby inhibiting the keyboard. The bar code scanner then transmits the decoded bar code to the PC as a sequence of data bytes. The bar code scanner also implements any communications that are required between the PC and the keyboard during this time.

  • Patent number: 6527193
    Abstract: The subject of the invention is method and device system for entering and retrieving information in the surface layer of objects made of solid matters. The information is entered with a (concentrated) beam directed to the surface and having a power density selected to induce permanent change at least in the surface layer of the material's structure in a way that the power density of the beam is smaller that the power density of the beam causing visible deformation, but bigger than that of the beam that causes (within the order of magnitude of the beam's diameter) inhomogeneities commensurable with the structural inhomogeneities generally present in the material. The invention can be used for all materials, the structure or internal stress of which can be modified with high energy density surface treatment (at the location of the treatment) (specially with the local laser treatment of ferromagnetic material).

  • Patent number: 6527177
    Abstract: In a conventional method which defines an authentication key for each record, as the number of the records is increased in an access right management for records in a memory of an IC card, the number of the types of authentication keys is also increased to require a larger memory area for storing the authentication keys, thus causing lower memory efficiency. In order to solve such a problem, terminal types (ex. “0H”-“7H”) are defined for interrogators, so that only the number of authentication keys equal to the number of the terminal types are stored. Each record has the number of access permission bits equal to the number of the terminal types, and specifies terminal types, to which an access is permitted, by setting the bits ON or OFF.

  • Patent number: 6508404
    Abstract: A scanner for optically scanning coded symbologies including a signal processing unit for pre-processing the scanned symbology information and a hardware symbology locating unit. An analog signal related to the reflectivity of the different portions of the coded symbology is obtained and is converted to digital gray-scale. The portion of the analog signal which corresponds to the substrate reflectance (absolute contrast) is removed, and the available dynamic range of the analog to digital converter is used only for the information-bearing portion of the signal (relative contrast). Since all of the decodable information is ultimately encoded in binary form, the information-bearing portion of the signal is retained. The hardware symbology locating unit includes a plurality of shift registers, each of which derives a value from an input seed which is based upon the width of a detected coded symbology element. The value of a subsequent input seed is compared to the values generated from a prior input seed.

  • Patent number: 6488209
    Abstract: A method and system for dynamically wedging data received from one or more automatic data collection (“ADC”) devices on an ADC device platform into a destination application based upon wedging criteria. A dynamic wedge receives data from one or more ADC devices and automatically wedges the data into applications based upon user-provided data characteristics or a predetermined set of rules. Applicable wedging criteria used to route data include those that are user-composed and those that pertain to firmware or software characteristics. The dynamic wedge may comprise an ADC data server, ADC device handlers, ADC protocol handlers, and a wedging grid for retaining wedging directives. The ADC data server receives wedging directives from local and remote client applications and stores the wedging directives in the wedging grid. When data arrives from an ADC device, the ADC data server analyzes the data to determine its characteristics.
