Abstract: Provided is a radio formed to be capable of performing wireless communication with sensors, and configured to be connected, through one communication port via wired communication, to a slave control apparatus configured to be communicably connected to a master control apparatus with a predetermined communication method. The radio generates one communication packet formed with the predetermined communication method and transmitted from the radio to the slave control apparatus, such that pieces of measured data measured by the sensors are included in the one communication packet in accordance with a predetermined order in which the slave control apparatus or the master control apparatus can determine which sensor measured which piece of the measured data of the sensors, and the radio transmits the generated one communication packet to the slave control apparatus via wired communication.

Abstract: Provided is a radio formed to be capable of performing wireless communication with a sensor that measures a predetermined environmental parameter in a predetermined closed space, the radio including an antenna portion disposed in the predetermined closed space and for performing wireless communication with the sensor, and a control unit that controls a mode by which the antenna portion transmits and receives wireless radio waves such that standing waves envisaged to be formed in the predetermined closed space based on radio waves transmitted from the sensor to the antenna portion, or standing waves envisaged to be formed in the predetermined closed space based on radio waves transmitted from the antenna portion to the sensor change with the lapse of time during the wireless communication.

Abstract: Provided is a radio formed to be capable of performing wireless communication with one driving apparatus, and configured to be connected, through one communication port via wired communication, to a slave control apparatus configured to be communicably connected to a master control apparatus with a predetermined communication method, the radio including an identification information collection unit collecting, from the one driving apparatus, identification information for identifying the one driving apparatus, when the radio is initially connected to the one driving apparatus via wireless communication, and a transfer control unit mediating data transfer between the master control apparatus and the one driving apparatus, such that the one driving apparatus is directly connected to the one communication port in a virtual manner, based on the identification information of the one driving apparatus collected by the identification information collection unit.

Abstract: The knowledge of an expert user expressing the relationships between phenomena and a conclusion (a rule) is stored prior to the use of the device. Input data are applied to this knowledge in order to make an inference. The possibility of the conclusion is calculated, and the clearness of each phenomenon relative to the possibility of each conclusion is determined by the fuzzy inference device. The phenomena related to a single conclusion which have low static information amount or clearness are selectively eliminated. In this way the rule can be adjusted, the processing time can be reduced, and the reliability of the conclusion can be improved. In second and third embodiments of the invention, the knowledge of an expert user expressing the relationships between phenomena and conclusions (rules) is stored prior to the use of the device. Inferences are made by applying input data to this knowledge.
