A feature extraction method includes: the step of grouping a cluster of features, in which an internal of the respective features is less than or equal to a predetermined grouping interval, to form a feature group, for a plurality of features of which feature information including at least information of a position and a feature type is included in a predetermined feature information storage unit; the step of excluding the feature, not suitable for use in an image recognition process of the feature with respect to image information, from the cluster of the features within the feature group; and the step of extracting a part or all of one or more of the features within the feature group remaining as a result of the exclusion step as a target feature suitable for the use in the image recognition process.

A game system includes a game apparatus and a controller. The controller is furnished with an acceleration sensor for detecting accelerations in at least two axis directions. Game processing corresponding to the kind of an acceleration input by means of the controller is executed. For determining the kind, reference timing when acceleration in a first-axis direction is below a threshold value to take on a minimum value is detected. Then, it is determined whether or not an angle between acceleration change vectors before and after the reference timing is equal to or more than a predetermined angle. When the angle is not equal to or more than the predetermined angle, it is determined that the acceleration input is an acceleration input in any one of the two-axis directions, and when the angle is equal to or more than the predetermined angle, it is determined that the acceleration input is an acceleration input in a direction including the two-axis directions as components.

In conventional systems using an onboard camera disposed rearward of a vehicle for recognizing an object surrounding the vehicle, the object is recognized by the camera disposed rearward of the vehicle. In the image recognized by the camera, a road surface marking taken by the camera appears at a lower end of a screen of the image, which makes it difficult to predict a specific position in the screen from which the road surface marking appears. Further, an angle of depression of the camera is large, and it is a short period of time to acquire the object. Therefore, it is difficult to improve a recognition rate and to reduce false recognition. Results of recognition (type, position, angle, recognition time) made by a camera disposed forward of the vehicle, are used to predict a specific timing and a specific position of a field of view of a camera disposed rearward of the vehicle, at which the object appears. Parameters of recognition logic of the rearwardly disposed camera and processing timing are then optimally adjusted. Further, luminance information of the image from the forwardly disposed camera is used to predict possible changes to be made in luminance of the field of view of the rearwardly disposed camera. Gain and exposure time of the rearwardly disposed camera are then adjusted.

A sheet-convey device, includes a holder, a convey member, and a recognizer. On the holder, a first sheet having a first width and a second sheet having a second width larger than the first width are placeable. The convey member conveys a sheet placed on the holder in a predetermined direction. The recognizer recognizes a width of the sheet and includes first and second sensors for sensing whether a part of the sheet is present at respective first and second positions of the holder. The first position is located inside of the first width in the widthwise direction with the first sheet placed on the holder, while the second position is located outside of the first width and inside of the second width with the second sheet placed on the holder. The second position is located upstream of the first position in the predetermined direction.

A sheet-convey device, including: a holder on which a first sheet having a first width and a second sheet having a second width larger than the first width are placeable at a predetermined setting position; a convey member which conveys a sheet placed on the holder in a predetermined direction perpendicular to a widthwise direction of the sheet; a recognizer which recognizes a width of the sheet; wherein the recognizer includes first and second sensors for sensing whether a part of the sheet is present at respective first and second positions of the holder; wherein the first position is located inside of the first width in the widthwise direction with the first sheet placed on the holder, while the second position is located outside of the first width with the first sheet placed on the sheet holder and inside of the second width with the second sheet placed on the holder; and wherein the second position is located upstream of the first position in the predetermined direction.

A pressurized flow of breathable gas is delivered to the airway of a subject in accordance with a therapy regimen. One or more fluid parameters of the pressurized flow of breathable gas are adjusted based on the therapy regimen. The therapy regimen dictates that such adjustments be made based on the respiratory state of the subject. Transitions in respiratory state are identified without relying on measurement or estimation of flow at or near the airway of subject. Transitions in respiratory state are identified based on changes in the first time derivative of flow at or near the airway of the subject. In one embodiment, an effort parameter is determined that approximates the second time derivative of flow. Based on comparisons of the effort parameter to a dynamic threshold, transitions in respiratory state are identified.
