摘要:
In an exemplary assessment system of speech sound listening, an output section presents a speech sound to a user as an auditory stimulation; a positive component determination section determines whether a positive component appears in an event-related potential of an electroencephalogram signal of the user in a range from 600-900 ms from a starting point, the starting point being a point in time at which the speech sound is presented, and outputs an assessment result as to whether the user is listening to the speech sound with strife or not; and a negative component determination section determines whether a negative component appears in the event-related potential in a range from 100-300 ms from a starting point, the starting point being the point in time at which the speech sound is presented, and outputs an assessment result as to whether the user is annoyed by the speech sound or not.

An electroencephalogram measurement apparatus includes: an electroencephalogram measurement section for measuring an electroencephalogram of a user by using a plurality of electrodes; an electro-acoustic transducer for presenting an acoustic signal to the user, the electro-acoustic transducer being in a vicinity of at least one electrode among the plurality of electrodes while the electroencephalogram measurement section is worn by the user; an amplitude envelope extraction section for extracting an amplitude envelope of the acoustic signal presented by the electro-acoustic transducer; a frequency analysis section for applying a frequency analysis to the amplitude envelope extracted by the amplitude envelope extraction section; and a noise estimation section for estimating an electrical noise which is mixed at the at least one electrode by using a previously provided set of transform rules and the extracted amplitude envelope.

A safety device for a machine having an action part for processing or moving an object includes: a posture obtainment unit configured to obtain a plurality of posture data indicating a posture of at least part of the lower body of a worker; and a preparatory movement determination unit configured to determine that a preparatory movement preceding a dangerous movement which brings at least part of the upper body of the worker closer to a working area of the action part is being performed in the case where a change in the posture indicated by the plurality of posture data shows that the worker is shifting a center of gravity of whole body of the worker in an orientation away from the working area of the action part without changing positions of both feet.

A sheet-processing device for performing various sheet post-processing functions at high speed and implementing a compact structure includes a compiler 106 that causes a stacked sheet to wait until stapling processing is performed; a jogger 107 that aligns the sheet stacked on the compiler 106; a stapler device 24 that performs the stapling processing to the sheet aligned by the jogger 107 as many as the setting number of sheets; and a sheet transfer pathway 105 through which the sheet in which an image is formed is delivered to the compiler 106.

A vehicle control device (10) is provided that can predict a driving operation of a driver earlier to respond to the driving operation quickly. The vehicle control device (10) includes: a posture measuring unit (11) to measure a posture indicating a state of at least one of the buttock region, the upper pelvic region, and the driver's leg opposite to the other leg with which the driver operates a brake or an accelerator; a posture change detection unit (12) to detect a posture change measured; a preparatory movement identification unit (13) to identify whether the posture change is caused by the driver's preparatory movement spontaneously made before the brake or accelerator operation, based on whether the posture change detected satisfies a predetermined condition; and a vehicle control unit (14) to control the vehicle when it is identified that the posture change has been caused by the preparatory movement.
