Adjustment in the amount of projected image distortion correction

An exemplary aspect of the invention can provide a method for easily adjusting the distortion of a projected image. In adjusting the amount of distortion correction, values of the amount of distortion correction for a desired outline form to be formed based on desired positions are calculated after the desired positions can be specified. Then whether all the calculated values of the amount of distortion correction are within a predetermined range where an original image is transformable into a distortion correction image can be judged. If all the calculated values of the amount of distortion correction are within the predetermined range, the calculated values of the amount of distortion correction can be set in an image distortion correction part. If a value out of the calculated values of the amount of distortion correction is beyond the predetermined range, outlines corresponding to at least part of the outline form of the projected image are produced, instead of setting the calculated values of the amount of distortion correction in the image distortion correction part. An outline corresponding to the amount of distortion correction beyond the predetermined range can be made differently from an outline corresponding to the amount of distortion correction within the predetermined range, so that each is identified.

Traffic guidance system for passengers going out of railway passenger station

The invention discloses a traffic guidance system for passengers going out of railway passenger station, which comprises a plurality of information prompt boards suspended at intervals on the top of an out-of-station passageway, a plurality of transfer digital maps and information inquiry machines arranged in information expanding regions at both sides of an exit passageway and an information guidance identification subsystem in the out-of-station passageway. By using the system, the passengers can acquire required real-time transfer information from the information prompt boards; if the passengers can not acquire enough information from the information prompt boards or need to acquire personalized information, the passengers can go into the information expanding regions to acquire information by using the transfer digital maps and the information inquiry machines by self-service; and the passengers can obtain a continuous guidance for the out-of-station process based on various information prompt identifications of the information guidance identification subsystem, so that the passengers can arrive at a transfer site for transfer. The invention can realize the out-of-station walk guidance and the out-of-station transfer prompt for passengers, and achieve good guidance effect and high transfer efficiency.

Novel thrombus-taking stent and thrombus taking device comprising thrombus-taking stent

The invention relates to the field of medical devices, in particular to a novel thrombus-taking stent and a thrombus taking device comprising the thrombus-taking stent. The novel thrombus-taking stentincludes a stent body which has circumferential self-expansion along the longitudinal axis of the stent, wherein the stent body comprises a plurality of spherical stent units, the stent rods of eachspherical stent unit have high radial support force, and a three-dimensional structure is formed by each spherical stent unit node and the corresponding stent rods; the stent rods can be quickly embedded in thrombi, and a blood vessel is anchored by the stent rods, so that the stability of thrombus capture is increased, and the possibility of thrombus slip is reduced; and an image developing material which is made from a material without perspective of rays is arranged from the distal end of the stent to the proximal end of the stent, runs through the entire stent, and runs through the range which includes both ends of the stent, space among the spherical stent units and the stent rods, and the effective length of the thrombus-taking stent can be marked accurately. Through the thrombus-taking stent which are formed through connection of a plurality of spherical units, the invalid working length of the stent can be reduced, the flexibility and adherence of the stent body can be improvedeffectively, and the operation convenience of a doctor can be improved.

Vehicle lamp

A vehicle headlamp includes a reflector configured to forward reflect light from a segment light source extending in a vehicle width direction such that a light distribution pattern is formed that has a cut-off line at an upper end thereof. The segment light source is arranged such that a first predetermined point located at a front end edge of the segment light source at end edges thereof in right and left directions in a plan view of the vehicle headlamp is located on a first reference axis extending in the longitudinal direction of the vehicle. A reflecting surface of the reflector is split into a plurality of reflection regions. At least one of the plurality of reflection regions, in the plan view of the vehicle headlamp, are constituted as a fan-like reflection region surrounded by a first straight line extending obliquely downward from the first reference axis on the side of the first reference axis opposite the segment light source in the right and left directions, and a second straight line extending immediately downward from the first reference axis. The fan-like reflection region is constituted with a curved surface that deflects, diffuses, or reflects the light from the segment light source in a direction orthogonal to the first straight line, with a paraboloid of revolution that uses the first predetermined point as a focal point and uses the first reference axis as a center axis formed as a reference plane so as to form the cut-off line.
