Abstract: This voice detection device is composed of a myoelectric signal acquisition part for acquiring, from a plurality of regions, myoelectric signals generated at the time of a vocalization operation, a parameter calculation part for calculating, as parameters, the fluctuations of the acquired myoelectric signals relative to a predetermined value in every channel corresponding to one of the plurality of regions, a vowel vocalization recognition part for specifying the vowel vocalization operation timing at the time of the vocalization operation, based on the fluctuations of the calculated parameters, and a vowel specification part for specifying a vowel corresponding to the vocalization operation, based on the fluctuation condition of the parameters before and after the specified vocalization operation timing in every channel.

Abstract: 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.

Abstract: An object is to provide an authentication apparatus with improved effect of preventing unauthorized use, which is applied to personal equipment carrying out a predetermined function. This authentication apparatus includes a functional part carrying out a predetermined function to be used by a user, an electromyogram acquiring part for measuring a change of an electromyogram caused by a motion of a muscle of the user, and a state transition part for implementing a transition into a state in which the user can use the predetermined function of the functional part, according to authentication of the user based on the result of the measurement.
