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: The ultrasound examination system automatically detects a lesion, based on a dynamic image including a plurality of frame arrays that are temporally continuous and are output from the ultrasound examination apparatus with an ultrasonic probe being manipulated. Detection accuracy of the ultrasound examination system can be increased. A feature extractor in a frame checker extracts cubic higher-order local autocorrelation features from each frame of a plurality frames that constitute a dynamic image of a human body part as obtained from an ultrasound examination apparatus while an examiner manipulates an ultrasonic probe on the examinee. A final determinator determines that the frame in question is a normal frame when a speed determinator determines that the speed of the ultrasonic probe is not a normal speed even though the frame in question can be determined as an abnormal frame containing a lesion.
