  • Publication number: 20130297260
    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: 20130272714
    Abstract: A state control system comprises a portable terminal and a control apparatus. The portable terminal sends a signal including identification information to an external. The control apparatus controls a controlled object in either one of a locked state and an unlocked state based on the signal sent from the portable terminal. The portable terminal sends a first signal, in a case where a event detector has not detected the event, and sends a second signal having a data length longer than a data length of the first signal, in a case where the event detector has detected the event. The control apparatus controls a controlled object to the unlocked state in a case where the controlled object is in the locked state and the controlled apparatus receives the second signal.

  • Publication number: 20120139750
    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: 8036883
    Abstract: By individuals in an organization possessing a portable node and acquiring sound information, an electronic device and a system that analyze human behavior, group formation, and an activity level of the organization and a system is provided. In an electronic device that has a radio communication unit and a microcomputer, sound is converted into an electrical signal by a microphone, and sound waveform information and characteristic information of sound are obtained using an amplifier, a filter, and an envelope generating circuit. An envelope signal being characteristic information of sound is compared with a reference value by a comparator. Characteristic information of sound when the signal does not reach the reference value, and sound waveform information when greater than the reference value are transmitted from the radio communication unit. The server learns human behavior, group formation; and an activity level of an organization by receiving and analyzing these pieces of information.

  • Patent number: 7936255
    Abstract: Face-to-face detection by infrared-ray communication is effective in grasping interaction between persons. However the problem here is that infrared rays have a high directivity and detection fails unless the persons face each other right in front. Sensor signals having a high directivity and sensor signals having a low directivity are obtained from a sensor terminal (TR) carried by a person. Firstly, information on relative position is obtained with a sensor (TRIR) of infrared rays or the like having a high directivity and an initial group is formed at an application server (AS). A feature amount such as sound that has a low directivity and can sense surrounding environmental information is extracted from among the terminals (TRs) belonging to the initial group by personal feature extraction (ASIF), correlation with terminals (TRs) not belonging to a group is obtained, and thereby whether or not those terminals (TRs) belong to an identical group is judged.
