Abstract: A viewing material evaluating method includes: a brain activity measuring step of measuring a brain activity of a test subject who views a viewing material by using a brain activity measuring unit; a first matrix generating step of generating a first matrix estimating a semantic content of perception of the test subject on the basis of a measurement result acquired in the brain activity measuring step by using a first matrix generating unit; a second matrix generating step of generating a second matrix by performing natural language processing for text information representing a planning intention of the viewing material by using a second matrix generating unit; and a similarity calculating step of calculating similarity between the first matrix and the second matrix by using a similarity calculating unit.

Abstract: A material evaluating method includes: a brain activity measuring step of presenting a training material to a test subject and measuring a brain activity by using a brain activity measuring unit; a semantic space building step of building an intracerebral semantic space representing an intracerebral semantic relation between the brain activity and a word appearing in a language description on the basis of a measurement result acquired in the brain activity measuring step and the language description acquired by performing natural language processing for a content of the training material by using a semantic space building unit; a first estimation step of estimating a first position corresponding to a content of a new material in the intracerebral semantic space from a language description acquired by performing natural language processing for the content of the new material by using a material estimating unit; a second estimation step of estimating a second position corresponding to an object word in the intr

Abstract: A perceptual semantic content estimation method includes: (A) inputting, to data processing means, brain activity induced in a subject by a training stimulation and detected as an output of a brain activity detection means and an annotation of a perceptual content; (B) associating a sematic space representation of the training stimulation and the output of the brain activity detection means in a stored semantic space and storing the association in a training result information storage means; (C) inputting, to the data processing means, an output when the brain activity detection means detects brain activity induced by a novel stimulation, and obtaining a probability distribution in the semantic space which represents perceptual semantic contents for the output of the novel stimulation-induced brain activity by the brain activity detection means on the basis of the association; and (D) estimating a highly probable perceptual semantic content on the basis of the probability distribution.

Abstract: A power seat slide device capable of changing not only to an electric operation but also to an manual operation, and preventing half-lock in spite of a manually operable structure. For front-rear movement, a rack attached to a lower rail and a pinion meshed with the rack are used, and a driving force of a motor is transmitted to the pinion, which enables the use in an electric mode. As no slide screw is used, while the motor is not energized, rotating the pinion causes an output shaft of the motor to rotate, so that manual adjustment becomes possible.

Abstract: A power seat for a vehicle is provided with an upper channel fixedly attached to a seat, a lower channel fixedly attached to a floor of the vehicle, a nut unit fixedly attached to one of the upper channel and the lower channel, a driver shaft passing through the nut unit, a motor mounted on the other one of the upper channel and the lower channel, a transmission unit for transmitting a torque of the motor to the driver shaft. The nut unit includes a nut block having an internally threaded through hole through which the driver shaft passes, a holder having a front standing wall, a rear standing wall, and a coupling portion coupling the front standing wall and the rear standing wall so as to define a space for holding the nut block, each of the front standing wall and the rear standing wall having buttress walls projecting outward.
