  • Publication number: 20090160614
    Abstract: Detecting whether components are combined and coupled correctly in assembly work is performed by correct and simple operations. The proposed method includes reading a first IC tag attached to a joint part of a first component and a second IC tag attached to a joint part of a second component together in a manner of preventing collision and determining whether the first component and the second component are coupled correctly, based on information representing mating relations of IC tags memorized beforehand.

  • Patent number: 7547975
    Abstract: A module with embedded semiconductor IC of the present invention includes a first resin layer, a second resin layer, post electrodes passing through the first and second resin layers, and a semiconductor IC mounted as embedded between the first resin layer and the second resin layer. Stud bumps are formed on land electrodes of the semiconductor IC and positioned with respect to the post electrodes. Owing to this positioning of the stud bumps formed on the semiconductor IC with respect to the post electrodes, the planar position of the stud bumps is substantially fixed. As a result, it is possible to use a semiconductor IC having a very narrow electrode pitch of 100 ?m or smaller, particularly of around 60 ?m.

  • Publication number: 20080071892
    Abstract: A sensor node may be used for another purpose for a moment and may also be replaced. By configuring, for a sensor node, a logic node which is provided with the physical node use information indicating whether or not the sensor node is in use and the logical node use information indicating whether or not the sensor node is provided as a logic node, a sensor node to be replaced may be specified based on the replacement request of the sensor node, a sensor node is selected which is configured as logic node providing the physical node use information indicating that the sensor node is not used and the logic node use information indicating that the sensor node is provided as the logic node, thus selected sensor node is identified as the replacing sensor node to achieve the replacement from the replaced sensor node to the replacing sensor node.

  • Publication number: 20080070614
    Abstract: A plural-data transmission Start message is transmitted prior to transmission of plural data to an intermittent operation type wireless communications terminal, and when transmission of plural data is completed, a plural-data transmission End message is transmitted. The terminal which received the plural-data transmission Start message can change over the sleep period of the aforesaid intermittent operation to a shorter sleep period. Thereby, an improvement in the response performance in the case of plural-data delivery can be simultaneously obtained while maintaining the low power performance of a sensor node.

  • Publication number: 20080055113
    Abstract: In a sensor network system for transferring sensing data measured by a sensor node to a host server based upon a process condition, the process condition can be easily set. The host server (4) previously sets a transmission condition which is used to transmit only an event satisfying a preset condition to the host server (4). When the host server (4) receives a joined event from a PAN management server (2), the host server (4) transmits to the PAN management server (2) a transmission condition corresponding to an identifier of an ID of a sensor node (1) of a transmission source of the joined event, and the PAN management server (2) transfers only an observed event satisfying the transmission condition to the host server (4).

  • Publication number: 20080031139
    Abstract: An overload on a communication path in a sensor network system is prevented while transferring information from a sensor node as close to real time as possible. When the transfer rate of events transferred from a boundary node (DR) toward a gateway (GW) exceeds a limit transfer rate (VL), one of nodes on the sensor node (S) side whose transmission rate meets a preset condition is identified as an excess transmission rate node. The excess transmission rate node, or a node that is not the excess transmission rate node and whose transmission rate should be reduced, is chosen as a deceleration node. A node that reduces the transmission rate of events from the deceleration node, or the transfer rate of the events, is chosen as a deceleration processing executing node. The deceleration processing executing node is instructed to execute preset processing.

  • Patent number: 7152131
    Abstract: In a data processor including a master circuit that issues an access request and slave circuits that perform processing in response to the access request received from the master circuit, the disclosed invention enables the master circuit to access all data areas of the slave circuits even if the master circuit does not have an access command in data size suitable for accessing the slave circuit. An access size control unit that can convert access size input from the master circuit to data size in which the slave circuit accepts access is installed between the master circuit and the slave circuit. The access size control unit retains at least one address for access size setting. As the master circuit accesses the appropriate address for access size setting, the access size conversion procedure can be carried out.

  • Publication number: 20060174052
    Abstract: In an LSI system using an on-chip bus, when a transfer on the bus is delayed due to a fully loaded buffer in a destination module, a source module cannot proceed to the next processing. Such an unwanted situation is eliminated by a transferring buffer which is provided on a transfer path in an on-chip bus on the LSI for temporarily storing transfer data. With this transferring buffer, even if a buffer within a slave module, specified as the destination, is fully loaded and cannot accept any more transfer, a bus master can transfer data to the transferring buffer provided on the on-chip bus. Thus, the bus master is not kept waiting for execution of a transfer, irrespective of the state of the buffer within the slave, thereby improving the processing performance of the entire system.

  • Publication number: 20060128414
    Abstract: In a wireless communication system having a base station and a terminal, it is important to extend the operating life of the terminal in the case of using a battery as the power supply of the terminal. Particularly in the case where a state in which a base station is not present in the range within which the terminal can communicate lasts long, the reduction of the electric power consumption during the standby of the terminal becomes an issue. The terminal monitors the received signal power strength of a signal transmitted by the base station. When the power strength exceeds a prescribed value, it is considered that the base station is present and the base station performs operations for carrying out communication with the base station.

  • Patent number: 7030896
    Abstract: A printing system using a thermal printer capable of readily visually discriminating the background data and sales data, saving waste of paper resources and improving the printing speed is provided. When printing basic data and background data in superimposition on each other in a thermal printer having a matrix array of color generation dots, data representing density gradation values are supplied to each color generation dot for printing background data with density lower than the density of the basic data. The direction of the basic data is set to a direction different by 90 degrees, for instance, from the direction of the array of the basic data. The visual discrimination of the two different kinds of data is improved.
