Abstract: An IC memory card for use with a host information processing has an interface with the host information processor, a common memory having one or more IC memories and a security circuit for prohibiting access to the common memory if address data input from the host processor does not coincide with preset data. The IC memory card may further provide with an attribute memory which stores a security data and attribute information about the IC card wherein the security circuit checks not only the address data but also the data read out from the attribute memory to enhance the security.

Abstract: A semiconductor device is provided with a data security protection function. A ciphering program is given from a control device to a logic-changeable logical circuit. The logical circuit changes its logic in accordance with the ciphering program. Data to be stored is ciphered on the basis of the changed logic, and then stored in a memory device. It is possible to store the data in the memory device as it is and to cipher the data on the basis of the changed logic when the data is output from the memory device. Further, it is possible to cipher an address related to the data. Further, a deciphering program is given from the control device to the logic circuit. The logic circuit changes its logic on the basis of the deciphering program. The ciphered data is applied a deciphering process on the basis of the changed logic. The ciphering and/or the deciphering processes can be stored in a computer readable medium for causing a computer to execute those processes.

Abstract: A portable data collection device providing for dataform decoding and color imaging. An imaging assembly is provided that includes a board camera having black and white circuitry and generates a composite video signal representing an image of a target area of the imaging assembly when actuated. The imaging assembly includes a two dimensional photosensor array overlaid by a color filter having a repeating pattern of four color filter elements.

The recess can be closed by a cover that is connected to the card base structure via a flexible area. The cap can thereby be pivoted relative to the base body of the card, with the flexible area acting as a hinge. The flexible region and the cover may either be construed in one piece with the card base structure, or the flexible area may be part of a label.

Abstract: This disclosure provides a handheld writing device and a related data entry system. In particular, a digital electronic clipboard is used to mount pages or forms utilized in forms processing applications, such as inventory tracking. A stylus having a writing tip at one end of the stylus and a bar code scanning mechanism at another end of the stylus is used to enter data on the pages or forms and scan bar codes appearing on the pages or forms themselves, or on a separate item to be associated with the form. The system detects whether bar code data or stylus position data is being generated and causes its CPU to responsively process entered data. In an alternative embodiment, the system also permits generation of only one of stylus position data and bar code data at any given time.

The bar code system is installed in the production line so as to immediately suspend the production line in case of a situation corresponding to production line stop conditions, thereby preventing repetitive occurrences of the same failure and sending-out of the same SET failure history even after another same defective is sent out.

Abstract: A transaction card reader for manually inserted cards includes a vertically moveable gate located just inward of the card insertion opening. The gate is moved from its closed or blocking position in response to the leading card edge engaging and applying symmetrical lifting forces to the gate. Guide members guide the vertical gate movement if the card is oriented at the correct angle in the insertion plane to produce symmetrical lifting forces. These guide members impede the gate from moving from its closed position if one card leading edge portion engages the gate before the other. In one exemplary embodiment, the gate includes a pair of spaced cam surfaces facing the user. If the leading card edge engages one cam surface before the other, the gate will skew and bind in a gateway. If both cam surfaces are engaged substantially simultaneously, the gate rises vertically in the gateway. A gate spring symmetrically biases the gate member toward the closed position.

Abstract: A lightweight, easy to grasp and manipulate hand-held optical scanning device for scanning and digitizing image data from a two-dimensional bar code symbol for subsequent decoding in a personal computer platform. The scanning device achieves a small footprint in the user's workspace by utilizing a non-folded, substantially vertical optical path extending from an image viewing area upwardly to a linear charge-coupled device (CCD) array upon which the successive rows of the target two-dimensional bar code symbol are imaged. The scanning device is easily aligned with the symbol by placing it behind the symbol, and scanning of the successive rows of the symbol is accomplished by swiping or rolling the scanning device towards the user. Mechanical rollers on the underside of the scanning device provide translation information for use in clocking data out of the linear CCD array in order to scan the successive rows of the two-dimensional bar code symbol.

Abstract: A smart card capable of adjusting voltages supplied from an external device. In the smart card, a voltage detector detects levels of the voltages supplied from the external device and generates enable signals, if the detected levels are lower than a predetermined level. A voltage controller converts levels of the voltages supplied from the external device into levels of operating voltages of the smart card, in response to the enable signals. A logic level converter converts logic levels of signals received from the external device into logic levels of the smart card, based on a voltage difference between the voltages from the external device and the converted operating voltages.
