Abstract: An object detection apparatus and method capable of detecting objects based on visual images captured by a self-moving unit. A sequential images output section makes a train of a first input image and a second input image sequential to the first input image and outputs said train. A local area image processor calculates local flows based on said first input image and said second input image. An inertia information acquiring section measures self-motion of the unit to calculate inertia information thereof. A global area image processor uses said inertia information to estimate global flow, which is a motion field of the entire view associated to the self-motion, using said global flow and said first input image and creates a predictive image of said second input image. The global area image processor then calculates differential image data, which is a difference between said predictive image and said second input image.

Abstract: In a hot press-bonding mark: the mark has a base sheet made of a non-woven fabric, a taffeta, a spongy material or the like; a thin film of a thermoplastic synthetic resin excellent in printability in an ink-jet or an ink-ribbon printing system is formed in one of opposite surfaces of the base sheet; an intermediate layer constructed of a thin film of a thermoplastic synthetic resin which does not react on any release agent is formed in the other of the opposite surfaces of the base sheet to leave the other of opposite surfaces of the intermediate layer alone; and, an adhesive layer comprising a hot-melt based thermoplastic synthetic resin is formed in the thus left-alone one of the opposite surfaces of the intermediate layer. If necessary, it is possible to peel off the mark from a uniform and like objects to which the mark is applied.

Abstract: An object detection apparatus is provided for detecting both stationary objects and moving objects accurately from an image captured from a moving mobile unit. The object detection apparatus of the present invention applies Gabor filter to two or more input images captured by an imaging device such as CCD camera mounted on a mobile unit, and calculates optical flow of local areas in the input images. Then the object detection apparatus closely removes optical flow produced by motion of the mobile unit by estimating optical flow produced from background of the input images. In other words, the object detection apparatus clarifies the area where object is not present (“ground”) in the input images. By removing such “ground” part, the area where objects seems to be present (“feature”) is extracted from the input images. Finally, the object detection apparatus determines whether objects are present or not using flow information of the extracted “feature” part.

Abstract: The object detection apparatus according to the invention detects an object based on input images that are captured sequentially in time in a moving unit. The apparatus generates an action command to be sent to the moving unit, calculates flow information for each local area in the input image, and estimates an action of the moving unit based on the flow information. The apparatus calculates a difference between the estimated action and the action command and then determines a specific local area as a figure area when such difference in association with that specific local area exhibits an error larger than a predetermined value. The apparatus determines presence/absence of an object in the figure area.

Abstract: The connector includes a male member with an engaging portion on its outer face, a female member with an inner space for receiving the male member and a pair of manipulating members provided in the female member from opposite sides. The engaging portion of the male member is received through and behind the pair of manipulating members in the inner space. Each manipulating member has a part which enters the track region of the engaging portion and an elastic piece. The coupling of the male and female members is reliably obtained by two opposite side engagements between the engaging portion of the male member and the pair of manipulating members and maintained by the thrusting force by the elastic piece.
