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.

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 plural transferring buffers which are provided in an on-chip bus on the LSI for temporarily storing transfer data. With the transferring buffers, 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 a 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. With the provision of plural transferring buffers, input/output operations can be performed in parallel.

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).

Abstract: Provided is an information processing system which has a plurality of tags, a tag reader, a digital-pen, and a server. The plurality of tags each hold a tag identifier. The tag reader reads the tag identifier held in each of the plurality of tags. The digital-pen reads location information, which identifies a location where handwriting is made on paper. The server keeps work record including information that associates the tag identifier recorded in the server in advance with the location on paper. When it is judged that the read tag identifier and a handwriting location identified by the location information are associated with each other, the server judges whether or not the read tag identifier matches the tag identifier recorded in advance that is associated by the work record with the handwriting location identified by the location information. The server outputs a result of the judging.

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.

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.
