A vehicle control device and a data rewriting system prevent a person having no permission from rewriting the data of the vehicle control device. When the vehicle control device rewrites the data thereof based on rewrite data distributed from a control center through a radio communication network, the vehicle control device performs a user identification check based on the verification whether an ID code manually inputted by a user coincides with an ID code previously stored in a vehicle. The vehicle control device permits the user to rewrite the data based on the distributed rewrite data on condition that the user is identified as a privileged user permitted to rewrite the data.

A defect detector in a data disc system includes a defect estimation unit and a defect length counter. The defect detector inputs a RF signal from a pick-up unit for generating a defect signal. The defect length counter interprets the defect signal using a wobble signal and a header position (ESFS) signal to generate defect length information. A system controller determines which sector of the data disc has unacceptable defect from the defect length information to reassign such a sector to another available sector on the data disc.

The present invention relates to a game program rewrite system for supplying data of a game program of a plurality of terminal stations from a host station and writing the data in portable information storage media applied to game execution units in the terminal stations in response to requests, and a program rewrite system suitable for this game program supply system, and aims at enabling construction of a game-on-demand system including a number of terminal stations with no excess of requirement to equipment of a network or the data throughput of the host station.In order to attain the above object, a host station (1) supplies data of a game program to a terminal station (2) online through a communication network. The data of the game program is supplied to the terminal station (2) offline too. The data of the game program preserved in the terminal station (2) is written in a game execution storage medium (20) in response to a request of a user.

A rewriting system comprises a plurality of electronic control units mounted on a vehicle, each of the plurality of electronic control units including a storage for storing control information, and a device for sending new control information to rewrite the control information stored in the storages of the plurality of electronic control units with the new control information. One of the plurality of electronic control units is configured to make a determination whether the rewriting in the other electronic control units has been completed in response to a completion of the rewriting in the one of the plurality of electronic control units, and make a notification of a result of the determination. Thus, the progress of the rewriting for a plurality of control units is automatically determined and notified to a user. The user can immediately recognize the progress of the rewriting work.

A vehicle control device and a data rewriting system prevent a person having no permission from rewriting the data of the vehicle control device. When the vehicle control device rewrites the data thereof based on rewrite data distributed from a control center (10) through a radio communication network (11), the vehicle control device performs a user identification check (S80 and S120) based on the verification whether an ID code manually inputted by a user coincides with an ID code previously stored in a vehicle (20). The vehicle control device permits the user to rewrite the data based on the distributed rewrite data on condition that the user is identified as a privileged user permitted to rewrite the data.

A Hardware Description Language (HDL) utilizing a Term Rewriting System (TRS) is provided that simplifies handling of clocks, and signaling between various clock domains of a multi-clock domain circuit specification. A specific clock data type is supplied for use with clock signals. Using the clock data type, and other requirements of a circuit specification, clock domain crossing between domains of clocks of the same clock family is handled implicitly. For clock domain crossing between clock domains driven by clocks of different clock families, a “hardware approach” and a “linguistic approach” are provided. A “hardware approach” provides facilities to explicitly specify a synchronizer, using, in part, TRS rules. A “linguistic approach” allows a designer to abstracts the instantiation of synchronizers and instead specify a circuit specification in terms of differently clocked interfaces.

Program data stored in the recording medium of a general control apparatus coupled to a network is stored in the recording medium of a control apparatus as a rewritten subject of program data in the following manner. First, program data 21 stored in a recording medium 12b contained within the general control apparatus 12 is sent via the network 15 of a vehicle to the recording medium 13a of a second control apparatus 13 as the rewritten subject of program data (see a path L1). In this case, the program data 21 stored in the recording medium 12b contained in the general control apparatus 12 for generally controlling the control apparatuses 13, 14 is sent to the network 15 of the vehicle when it is determined to be optimum by the CPU 12c of the general control apparatus 12. The program data sent to the network 15 of the vehicle is sent via the network 15 of the vehicle to the second control apparatus 13 as the rewritten subject of program data. Then, the second control apparatus 13 as the rewritten subject of program data stores the program data 21 sent via the network 15 of the vehicle into the recording medium 13a.

The invention discloses a behavior pattern-based net rewriting method and a behavior pattern-based net rewriting system for regions of variation of an electronic commerce procedural model. The behavior pattern-based net rewriting method comprises the following steps: performing critical-path analysis and classification processing on structural relationships between responsible parties and the regions of variation; packaging or hiding responsible parties not in the regions of variation; determining transition sequences of all the regions of variation for the condition that the responsible parties are in the regions of variation; enabling transitions in each sequence to form a procedural model set; calculating the supporting number of each transition in the corresponding procedural model set and the confidence number of each transition of which the supporting number is not 1 in the corresponding procedural model set according to a behavior action pattern, and packaging or hiding the transition of which the confidence number is minimal; judging the consistency and the compatibility of the procedural model before and after rewriting according to behavior consistency. According to the behavior pattern-based net rewriting method and the behavior pattern-based net rewriting system disclosed by the invention, the structural relationships and behavior relationships of the model are considered simultaneously, and therefore, the rewritten model is furthest kept consistent and compatible with a source model under the condition that the regions of variation are avoided, and moreover, system development is realized so as to facilitate use.

Provided is an image recording system for recording an image on a recording medium attached to a conveyed article, including: a conveyor device conveying the conveyed article in a predetermined conveying direction; and a recording device provided on at least one side of the conveyor device in a direction perpendicular to the conveying direction and capable of contactlessly recording the image on the recording medium being located at a position facing itself. The image includes a scan image to be read by a reading device. The conveyor device decelerates the conveyed article by observing a position at which the recording medium will face the recording device as a target stop position. The recording device records the scan image on the recording medium after the conveyed article reaches the target stop position and while the amplitude of vibration of the conveyed article is equal to or smaller than a reference value.

To prevent abnormal termination of a program rewriting process performed when an engine is stopped. A construction machine includes: an engine (13); an alternator (14) for generating an electric power by a power of the engine (13); an electric storage device (15) for storing the electric power generated by the alternator (14); a controller (12) for storing a currently used program, and performing a rewriting process of rewriting the currently used program with a renewal program using an electric power from the electric storage device (15) when the engine (13) is stopped; and a charge amount detection section (18e) for detecting a charge amount of the electric storage device (15). The controller (12) prohibits execution of the rewriting process when the charge amount detected by the charge amount detection section (18e) is smaller than a rewrite charge amount preliminarily set as a charge amount required for the rewriting process.
