Abstract: A mobile terminal capable of measuring a biological signal is provided. The terminal comprises a terminal body; an electrode for human body earth or system reference, placed on an outer surface of the terminal body so as to be contactable with the skin of a user of the mobile terminal; and differential electrodes. The measured biological signals include an electromyography signal and an electroencephalogram signal. The differential electrodes can be external to the terminal body and be connected via lead lines to the terminal body.

Abstract: A measuring device comprising a fixing member configured to fix to a fixation object, the fixing member having a nonconductive contact surface with the fixation object, an electrode mounted on an opposite side of the fixing member to the contact surface with the fixation object, the electrode configured to measure voltage on a measurement object, and a transmitter configured to transmit the measured voltage externally.

Abstract: The myo-electric information of the user is transmitted to the data center, learning with a high computation load for generating recognition parameters required for recognizing the utterance content based on the myo-electric information is performed, not by the mobile communication terminal, but by the data center. By this, compared with the case when learning is performed in the mobile communication terminal which has stricter limitations on processing speed and memory than a stationary type computer, efficient learning in a shorter time becomes possible. Since the recognition parameters acquired at the data center are transmitted to the mobile communication terminal, hereafter utterance content recognition can be appropriately performed by the recognition parameters matching the user only by the mobile communication terminal, without the mobile communication terminal transmitting/receiving information with a learning device.

Abstract: The object of the present invention is to keep a high success rate in recognition with a low-volume of sound signal, without being affected by noise.

Abstract: Information relating to an amount of muscle activity is extracted from a myo-electrical signal by activity amount information extraction means, and information recognition is performed by activity amount information recognition means using the information relating to the amount of muscle activity of a speaker. There is a prescribed correspondence relationship between the amount of muscle activity of a speaker and a phoneme uttered by a speaker, so the content of an utterance can be recognized with a high recognition rate by information recognition using information relating to an amount of muscle activity.

Abstract: A furnace 1 runs while repeating a cycle in which the furnace inside temperature varies along a preset pattern of temperature change with time under the control of a primary controller 12, and adjustment input r being applied to an enlarged system including the furnace 1 and the controller 12 is renewed at the end of each cycle of operation, based partly on output from a dual system with respect to the enlarged system, so as to reduce error between the preset temperature and the furnace inside temperature in the next cycle. The temperatures of heaters 2 of the furnace 1 are controlled by a secondary controller 35, and the set values at the input of the secondary controller 35 are given by output signals (.tau.) from the primary controller 12 which responds to the furnace inside temperatures (y). The order of the dual system is reduced, and the renewal of the adjustment input r is quickened.
