摘要:
A personal-identification-information transmitting unit transmits personal identification information. A portable authentication apparatus receives the personal identification information, and performs an authentication process based on the personal identification information received and personal identification information stored in the portable authentication apparatus in advance. The portable authentication apparatus includes a control unit that controls provision of at least one of predetermined data and software to the information processing apparatus, based on a result of the authentication process.

An apparatus enables development and debugging of a control program for controlling a relatively small product having rapid response without using an actual mechanism. A simulation unit simulates an operation of a mechanism, in a simulation cycle shorter than a control cycle, for a time corresponding to the control cycle, and outputs a state variable of the mechanism to a holding circuit. When the state variable is held in the holding circuit, a simulation control unit makes the simulation unit shift to a response waiting state and makes a control program executing unit calculate a controlled variable. When the controlled variable is held in the holding circuit, the simulation control unit makes the control program execution unit shift to a response waiting state and makes the simulation unit initiate a simulating operation. The apparatus is applied when a control program for every product requiring a precise servo control is developed.

A backup system is comprised of a main storage for storing original data and a plurality of local storages for distributing and storing the data. An encoding unit of the main storage server generates, after dividing the original data, a plurality of encoded data that is equal to or more than the dividing number by use of a code of which redundancy is variable. A distribution processing unit distributes the plurality of encoded data to the plurality of local storages, and causes the data to be stored therein. A restoring unit retrieves the encoded data corresponding to at least the division number of the original data from the local storages, and restores the original data. A redundancy control unit varies the redundancy in the encoding unit such that, the higher the importance of the data, the larger the redundancy. Furthermore, a distribution processing unit determines the distribution number such that the higher the reliability of the local storages, the more the number.

In a communication control system a reception-side terminal sends back transmission time information included in a transmission packet as an acknowledgment to a transmission-side terminal. The transmission-side terminal determines whether a response time, obtained from the transmission time information, is shorter than a threshold. When the response time is shorter, the transmission-side terminal controls so as to transmit to the reception-side terminal a larger number of packets than the number of packets upon transmission of the transmission packet, or to transmit the same number of packets as the number of packets upon transmission of the transmission packet.

A stored-program device includes a disguise-signal transmitting unit that obtains a disguise signal, and transmits the disguise signal to a computer, upon receiving a request from the computer, a program transferring unit that obtains the arbitrary program and transfers the arbitrary program to the computer, and an install controlling unit that controls the disguise-signal transmitting unit to transmit the disguise signal to the computer, and controls the program transferring unit to transfer the arbitrary program to the computer upon receiving a request from a install-program of the computer. The computer installs the arbitrary program transferred by the program transferring unit, using the install-program.

When each of a plurality of peers mutually connected through a network receives connection of a new peer, each peer forms group information in which the new peer has been grouped on the basis of comparison of distances on the network among three peers of the own peer, a representative peer of an existing group, and the new peer. When the data is transmitted from the own peer, path information in which destination information of each group which has been grouped on the basis of the group information and the own peer have been registered is formed and transmitted together with the data to the representative peer of each group. When distribution information is relayed from another peer, if the own peer is included in the destination information, the reception data is fetched and the own peer is deleted, thereafter, distribution information in which the destination information of each group which has been grouped on the basis of the group information and the own peer have been registered is formed and transmitted together with the data to the representative peer of each group.

An apparatus concurrently executing designing of a mechanism and developing of embedded software. A three-dimensional-mechanism model simulates an operation of the mechanism, an embedded software developing section develops a control program to control the designing and operation of the mechanism in parallel to each other, a first interface inputs designing data from a mechanism designing section to the three-dimensional-mechanism model simulator for being dynamically reflected on the three-dimensional-mechanism model, and a second interface transfers data between the three-dimensional-mechanism model simulator and the embedded software developing section while synchronizing the simulator and the embedded software developing section with each other.
