Abstract: The present invention provides a multiple-point grounding type foot portion supporting mechanism having excellent reliability, in which the respective supporting points passively follow unevenness of the grounding surface such as a road surface, and which is capable of quickly supporting foot bottoms at polygonal points and preventing falling over even on a grounding surface having level differences by fixing the supporting points when all supporting points are grounded.

Abstract: The present invention provides a method and system for solving the problem that re-drawing of a screen is instantaneously switched to and makes the screen hard to view when repeating the same operation or the like in the case of remote control of an apparatus using a browser, a server installed in a household electrical appliance or other apparatus, and applications thereof.

Abstract: A target detection system using an EHF radar and the image processing is disclosed, in which the processing time is shortened by mutually complementing the disadvantages of the EHF radar and the image processing thereby to improve the reliability. The system comprises a radar, an image acquisition unit and an image processing ECU. The microcomputer of the ECU specifies an image recognition area based on the power output from the radar, and carries out the image processing only within the specified recognition area for the image obtained from the image acquisition unit. By performing the image processing only for the area where a target is detected by the radar, the time required for image processing is shortened on the one hand and the erroneous detection of letters on the road surface or the like is eliminated.

Abstract: A target recognition apparatus that improves a recognition rate of a target by emphasizing vertical components of picked-up images, even if the target has a round shape of which the edges are is difficult to extract. The target recognition apparatus carries out the following processes. It compresses two images that have been simultaneously picked up with a left camera and a right camera that are mounted on a vehicle, in a lateral direction respectively. It detects both ends of the target in the two images, based on gradations of pixels in the images that have been compressed in this lateral direction. It measures a distance to the target, based on a parallax of the both detected ends of the target. A searching area of a target can be set based on the images compressed in a lateral direction.

Abstract: The invention provides an interpolation processing apparatus, an interpolation processing method and an image display apparatus wherein, when applied, for example, to format conversion for which a programmable video digital signal processor is used, processes such as format conversion can be executed by a comparatively simple process. The programmable video digital signal processor includes a plurality of element processors whose operations are controlled simultaneously and parallelly. The element processors are controlled so as to produce corresponding weighting coefficients based on number data individually allocated thereto. Where image data, for example, for one line are successively inputted to and processed by the element processors, an interpolation process is performed by an arithmetic operation process common to the element processors in which the position information of the number of lines or like is used as a variable.

Abstract: In an image recognition apparatus, a left camera and a right camera are provided so as to produce a parallax. A road surface indication recognizing section recognizes road surface indications contained in a left input image that is supplied from the left camera. An edge detecting section detects remaining edges other than the edges of the recognized road surface indications among all the edges in the left input image. A matching section extracts a reference pattern in the left input image that includes a detected edge, and conducts matching between the reference pattern and a right input image that is supplied from the right camera using a pattern matching method. Based on each matching result with the reference pattern, an object recognizing section recognizes an object in the visual fields and determines a distance from the recognized object to the image recognition apparatus.

Abstract: Novel phenylpyrazine derivatives of the following general formula: ##STR1## (where R.sup.1 is a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group or a hydroxyl group; and R.sup.2 is a halogen atom, a lower alkyl group, a lower alkoxy group or a hydroxyl group) have a high degree of thrombolytic activity in comparison with a known thrombolytic agent, Ticlopidine. Moreover, their toxicities are very low. Therefore, the derivatives are extremely useful as thrombolytic agents.
