Abstract: A fluid measuring device in which an ultrasonic probe provided on an outer pipeline surface transmits and receives ultrasonic waves to and from fluid in a pipeline to measure characteristics of the fluid on the basis of propagation time of the ultrasonic waves, features a wedge included in the ultrasonic probe and having an ultrasonic vibrator provided on a wedge surface. The ultrasonic vibrator may be horizontal to a surface contacting the pipeline so that ultrasonic waves enter the fluid vertically. The ultrasonic vibrator may be provided on a wedge surface inclined with respect to an axial direction of the pipeline so that ultrasonic waves enter the fluid obliquely. The fluid measuring device embodiments are capable of measuring fluid characteristics, such as the type and velocity of various fluids, easily and accurately even when it is difficult to allow an ultrasonic signal to pass through the fluid in a pipeline.

Abstract: A method and apparatus for reorganizing display of a railway timetable diagram. A method of reorganizing the display of a railway timetable diagram, including: generating a relational graph by using a multiple of stations in the railway timetable diagram and correlations between the stations; partitioning the relational graph according to a partition rule, where the partition rule reduces lines crossing in at least one page and/or section in at least one page in a reorganized railway timetable diagram, where the lines representing an association between respective stations along a path in the reorganized railway timetable diagram; and displaying a reorganized railway timetable diagram based on a result of the partitioning. An apparatus for reorganizing the display of a railway timetable diagram.

Abstract: The embarkation of passengers onto a vehicle of a transport installation with an aerial cable, comprising selectively served intermediate stations, is controlled by a programming device calculating the number of passengers allowed to go into a double-entrance security door and to embark onto a vehicle stopping at the station, according to the number of passengers in the vehicle and to the number of passengers disembarking from the vehicle at this station as they have compulsorily indicated when embarking.

Abstract: A transit center apparatus is provided having one or more modules attachable to a transit stop pole to provide one or more of the following conveniences to a transit stop patron: information in an optionally illuminated modular display apparatus, overhead illumination, video camera surveillance, and wireless communication. These conveniences are preferably provided through an overhead assembly and a rugged information display case. The overhead assembly houses one or more of the group consisting of solar cells, a rechargeable battery pack, overhead lights, a cell phone antenna, camera, and related circuitry. The information display case provides backlighting and houses a switch assembly. The display case is preferably constructed from extruded, interlocking aluminum frame members and is easily installable on existing support poles.
