Abstract: An intention decoding apparatus and a decoding method that quickly and precisely analyze brain waves for decoding an intention decision without requiring an advance brain wave measurement for, for example, a calibration step, and an intention conveyance assist apparatus, an intention conveyance assist system, and a program using a decoding result of the intention decision in the brain. The intention decoding apparatus that analyzes brain waves to decode an intention performs a process to examine a dispersion by classifying brain wave data of event-related potentials corresponding to a plurality of stimulus events into any one stimulus event and the other stimulus events among the plurality of stimulus events, on all the stimulus events, and identifies a classification where the dispersion becomes maximum to identify the one stimulus event in the classification as the intention. The intention conveyance assist apparatus includes a presentation unit that presents a decoding result.

Abstract: The shape of a moving object is reconstructed from a shot image under relatively-strong ambient light or an embedded image is demodulated from a video image in which an image that may not be visually recognized is embedded to display the image. The image processing method of the present invention includes irradiating flashing light to the surface of the object based on a spreading signal obtained by spread spectrum modulation, receiving reflected light from the surface of the object to output the signal including the image information, a filtering for eliminating noise including a low-frequency component from the signal including the image information, inverse-spreading the signal after the filtering to demodulate the signal, and outputting, based on a signal obtained by the demodulation, an image reflecting the state of the surface of the object.

Abstract: Provided is a brain function measurement device capable of improving the reliability of brain function measurement using a simple configuration. The brain function measurement device includes light source probes LD2 and LD12 for irradiating the scalp of a test subject with light beams; linearly polarizing films P2 and P3 for polarizing the light beams emitted from the light source probes LD2 and LD12 in a first direction; a linearly polarizing film P1 for blocking components in the first direction of reflected light beams that are generated as the light beams emitted from the linearly polarizing film P2 and P3 are reflected by the hairs of the test subject; and a detection probe PD1 for detecting the intensity of a light beam that has passed through the linearly polarizing film P1.

Abstract: Stable combustion becomes possible even in a super-lean combustion engine or an engine that carries out a large amount of EGR. In a spark discharge ignition promoting apparatus, non-thermal plasma is generated in a cylinder by a non-thermal plasma generating unit. The non-thermal plasma generating unit is provided at a location where a processed air-fuel mixture by the non-thermal plasma reaches a spark plug after an in-cylinder flow or where the air-fuel mixture exists around an electrode of the spark plug in a time when the air-fuel mixture keeps an easy combustion state. The spark plug ignites the processed air-fuel mixture by discharge of the spark plug at timing when the processed air-fuel mixture by the non-thermal plasma of an easy combustion state reaches the spark plug after an in-cylinder flow or timing when the air-fuel mixture of the easy combustion state exists around an electrode of the spark plug in the time when the air-fuel mixture keeps the easy combustion state.

Abstract: A high-frequency phase-locked oscillation circuit having an extremely narrow peak width and a stable frequency so that a high-frequency wave that is oscillated by the MR element solves a problem of a large peak width of oscillation spectrum. The high-frequency phase-locked oscillation circuit includes a magnetoresistive element that oscillates a high-frequency wave with an oscillating frequency; a reference signal source that outputs a reference signal with a reference frequency; a phase-locked loop circuit having a phase comparator, a loop filter, and a frequency divider; an adder that adds a phase error signal output from the loop filter and a bias voltage for oscillating the high-frequency wave from the magnetoresistive element, and that inputs an added bias voltage to the magnetoresistive element; and a filter provided between the frequency divider and the magnetoresistive element.
