Provided is an aerial vehicle having a structure in which a rotating body has been excluded from a portion that can be touched by a user during flight. An aerial vehicle includes: a balloon unit; a control unit provided at the bottom of the balloon unit; and a plurality of micro-mechanisms (micro blowers), each of which blows out air. The micro blowers have a structure in which a vibrating member is vibrated in a space in communication with a plurality of openings, thereby blowing out, through a second opening, the air that has flowed into the space through a first opening. The control unit controls the micro blowers to change the position or the attitude of the aerial vehicle.

A speaking period required for a voice recognition processing is detected with a simple and robust approach. A speaking period is detected based on an EMG generated when a speaker speaks. A large amplitude is observed in an EMG as muscular activity is caused when a speaker speaks. By observing this, a speaking period can be detected. The EMG can be measured from the speaker's skin via electrodes provided on a mobile-type terminal. Since a mobile-type terminal is usually pressed to the skin for use, affinity between this use form and the present invention is very high.

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.

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.

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.

A robot remote manipulation system is provided, including a bipedal walking robot and a remote manipulation device for remotely manipulating the bipedal walking robot. The robot is connected to the remote manipulation device via a communication network and controlled by controlling data from the remote manipulation device. In the system, the remote manipulation device comprises a pair of bilateral mechanical rotating elements providing a quantity of motion for each bilateral leg of the bipedal walking robot; and a controlling data transmitter for transmitting controlling data corresponding to the quantities of motion to the bipedal walking robot. The bipedal walking robot comprises a controlling data receiver for receiving the controlling data transmitted from the remote manipulation device; and a leg motion controller for processing the received controlling data and causing the bilateral legs to move forward or backward.

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.
