Abstract: PROBLEM TO BE SOLVED: To perform stable radio communication while securing a stable route by efficiently updating a routing table even when a radio station frequently moves. SOLUTION: In the wireless network for performing packet communication among respective radio stations, on the basis of a signal from an adjacent radio station containing the measured value of a signal-to-interference-noise ratio (SINR) when each of adjacent radio station receives a signal from a present station, the SINR watched from each of adjacent radio station for each azimuth in a horizontal plane with the present station as a center is found, the maximum SINR is selected for each adjacent radio station and defined as a degree of affinity, an adjacent link state table containing the relevant degree of affinity is generated, and an updating signal containing this table is transmitted and exchanged with each of other radio stations so that a global link state table containing the information of the adjacent link state table for each of relevant radio stations can be saved. On the basis of the global link state table, the route from a transmitting source radio station to a destination radio station is selected and a packet signal is routed.

Abstract: PROBLEM TO BE SOLVED: To suppress interference of the same channel on a wireless network, to increase a number of simultaneous communications in comparison with the conventional case and to increase a communication information quantity. SOLUTION: In the wireless network for performing packet communication between respective radio stations, on the basis of a signal from the adjacent radio station containing the measured value of a signal-to-interference-noise radio (SINR) when each of adjacent radio station receives a signal from the present station, the SINR watched from each of adjacent radio station for each azimuth within a horizontal plane with the present station as a center is found, the maximum SINR is selected for each adjacent radio station and defines it as a degree of affinity with each adjacent radio station, an adjacent link state table containing the relevant degree of affinity and the azimuth corresponding thereto is generated and on the basis of this table, radio communication is performed with the adjacent radio station of an opposite party. Besides, an under-communication table containing an azimuth for each adjacent radio station under radio communication with the other radio station is generated and on the basis of this table, a radio signal is transmitted by using an exclusive radiation pattern for turning a null point to the azimuth of the adjacent radio station under radio communication with the other radio station.

Abstract: PROBLEM TO BE SOLVED: To provide a device for studying a foreign language capable of presenting an evaluation result of a sentence in a foreign language pronounced by a learner so that the learner can efficiently train him-/herself on pronunciation of the foreign language. SOLUTION: A speech recognition part 114 and an arithmetic processing part 16 in the foreign language learning device 100 receive sentence speech information corresponding to the sentence pronounced by the learner 2, and separate the information into word speech information on each word contained in the sentence. The arithmetic processing part 116 makes a display device 120 show the evaluation result of a degree of coincidence (likelihood) of each word with a model speech for each word speech information.

Abstract: PROBLEM TO BE SOLVED: To provide an objective behavior estimation device and a service providing system for estimating what type of behavior a human being is performing to a specific object. SOLUTION: An objective behavior estimation device 10 includes a computer 30, and estimates what type of behavior a human being existing in an environment is making to a specific object on the basis of the location information of a human being (16) and an object (18) to be detected by a location detection system 12 installed in an environment. The computer 30 obtains the location history data for the prescribed time of the human being and the object from the location detection system 12, and calculates a featured value related with the human being and object by using the location history data, and to estimate the objective behavior by applying the calculated featured values to the discrimination formula. Thus, it is possible to estimate the behavior of the human being in a short time to the specific object, and to provide a service for quickly corresponding to the behavior.
