The data-managing center has a cost/number-of-days database, a reservation status database, and a design/manufacture status database. Each of the centers uses information contained in the databases of the data-managing center, performs two-way communication with the client, and thereby progresses the production of the semiconductor integrated circuit.

Abstract: There are provided a device and method for enabling entry of handwritten data, such as a signature, without use of an electronic tablet. In step S2-1, a user affixes a signature by means of moving a pen device 30 in midair. In step S2-2, camera means 20 photographs the pen device 30 and outputs the resultant image data. In step S2-3, coordinate computation means 22 determines coordinates of a pen tip of the pen means 30 on a screen on the basis of the image data (motion picture data), thereby determining signature data. In step S2-4, comparison verification means 40 compares and verifies the thus-determined signature data with reference data. If a similarity exists between the signature data and the reference data, there is output an authentication result showing “authentication of verification.” Thus, personal identification can be effected on the basis of the signature data written by the user in midair.

Abstract: In an MPEG data processing apparatus comprising a particular picture searching section which comprises a particular picture detector for detecting a current particular picture datum in MPEG video data, a particular picture interval holding section holds, as an estimated interval, an interval between the current particular picture datum and a predicted next particular picture. A next particular picture address calculating section calculates the predicted next particular picture on the basis of the estimated interval and a current address on reception of the estimated interval to produce the estimated address as a calculated address. A address controller accesses a memory at the calculated address to make the memory read a datum for the calculated address in a buffer.

Abstract: The MPEG video data stored in a video memory is successively written to a buffer 14 in accordance with an address held in an address register 2. When I picture is detected from the data read from the buffer, the information is fed to an I picture interval holder 18. The I picture interval holder 18 holds an address register value when the previous I picture is detected, subtracts the previous address register value from the present address register value when the present I picture is detected, and holds the value (interval between the previous I picture address and the present I picture address). A next I picture address calculator 17 adds the interval obtained in the I picture interval holder 18 to the present address value stored in the address register 12, subtracts a predetermined value from the calculated value, and predicts the next I picture address.

Abstract: A fault detection system applies known data to the input of a circuit being inspected for faults and examines the circuit output for expected results. Faults in a circuit are detected by receiving unexpected results at the circuit output. A fault detection circuit provides a fault signal that is enabled only when a reset line is activated. Activation of the reset line also prompts the known data to be applied to the circuit input. The known data can be derived from memory storage units that provide a known output upon activation of the reset signal. Accordingly, the system does not require parity bits or excessive hardware to provide fault detection for almost all modes of failure in a given circuit.

Another image data encoding system is also disclosed, that comprises an electronic watermark embedding means for embedding electronic watermark data selected from a plurality of types of electronic watermark data to the digital image data, wherein at least one of the plurality of types of electronic watermark data is predetermined electronic watermark data that does not affect the digital image data even if the electronic watermark data is embedded in the digital image data.

Abstract: An electronic watermark system invisibly embeds watermark information into original image data and the watermarked image data is transferred to a first medium. At the same time. the embedded watermark information is transferred to a second mediums. When a medium questioned is found, its watermark information can be easily identified by searching the second medium. Alternatively, the watermarked image data and the embedded watermark information are transferred to different storage areas of the same medium, respectively.
