  • Publication number: 20110099054
    Abstract: In an organization dynamics analysis service using a sensor, organization dynamics information is understandably provided to a lot of members on a customer side without receiving private information such as an individual name from the customer. Therefore, a sensor data associated with an ID is received from the customer site, and organization analysis is performed on a service provider side, and then, an organization analysis data based on the ID is fed back to the customer site. When the customer browses the organization analysis data, the ID is converted into the private information in a service gateway installed on the customer site in accordance with a conversion table for correspondence of the ID previously specified on the customer side and the private information (individual name), and is shown to the customer as the understandable information.

  • Publication number: 20090198475
    Abstract: An analysis sever capable of performing analysis among a large amount of sensor data in order to obtain an analysis result that a reader desires and outputting the result instantaneously. The analysis server rearranges the sensor data acquired from a sensor node into time series data. The analysis is performed separately for time trigger analysis (D) and for event trigger analysis (F) depending on analysis contents. In the time trigger analysis (D), analysis processing that is basically needed when visualizing a state of an organization is performed. In the event trigger analysis (F), an analysis result obtained by the time trigger analysis (D) is processed using the reader's desired information and is outputted.

  • Publication number: 20080297373
    Abstract: There is disclosed a sensor node capable of transmitting and receiving a large amount of data or data desired to be reliable without missing data, while preventing battery exhaustion and unnecessary compression of the transmission bandwidth. A name-tag type sensor node includes a detector for detecting connection of an external power supply. When the detector detects that the external power is supplied, the name-tag type sensor node transmits and receives a large amount of data, such as bulk transmission data, at an increased frequency by means of a data selector, a communication timing controller, and a wireless communication controller. Alternatively, the name-tag type sensor node transmits and receives the data desired to be reliable, such as rewriting data of firmware.

  • Patent number: RE41868
    Abstract: A memory cell with a small surface area is fabricated by forming source lines and data lines above and below and by running the channels to face up and down. The local data lines for each vertically stacked memory cell are connected to a global data line by way of separate selection by a molecular oxide semiconductor, and use of a large surface area is avoided by making joint use of peripheral circuits such as global data lines and sensing amplifiers by performing read and write operations in a timed multiplex manner. Moreover, data lines in multi-layers and memory cells (floating electrode cell) which are non-destructive with respect to readout are utilized to allow placement of memory cells at all intersecting points of word lines and data lines while having a folded data line structure. An improved noise tolerance is attained by establishing a standard threshold voltage for identical dummy cells even in any of the read verify, write verify and erase verify operations.
