Technical Examples
- A system and method are provided for clocking the speed of a moving object using a wireless terminal in a preview mode of a camera, wherein the method includes the steps of entering a preview mode for speed measurement when a speed measurement function is selected in a camera preview mode of the wireless terminal, measuring a moving distance of an object in the preview mode for speed measurement, measuring a moving time period of the object in the preview mode for speed measurement, and measuring and displaying a moving speed of the object by using the moving distance and moving time period of the object which have been measured. The method can further include steps of measuring a moving time period of the object by receiving image data of a moving object through two camera units in the preview mode for speed measurement, measuring a moving distance of the object through the two camera units in the preview mode for speed measurement, and measuring and displaying a moving speed of the object by using the moving distance and moving time period of the object which have been measured.
- A method of assessing the accuracy of a roadside traffic monitoring system (TMS) arranged to measure the speed and/or other parameters of vehicles passing a predetermined measurement point adjacent the TMS is disclosed. The method includes measuring the speed of each vehicle passing the measurement point using the TMS, measuring the moment in time that each vehicle passes the measurement point using the TMS, and recording the measured speeds and times as data pairs. The method further includes driving an Instrumented Probe Vehicle (IPV) at the measurement point, the IPV having an onboard system for measuring speed, determining the location of the IPV, determining a calibration time at which the determined location of the IPV corresponds to the location of the measurement point, and measuring a calibration speed of the IPV using the onboard system when the determined location of the IPV corresponds to the location of the measurement point.
- A device for the longitudinal guidance of a motor vehicle, having a speed sensor for measuring the driving speed of the vehicle; a distance sensor for measuring the distance to an obstacle possibly located in front of the vehicle; and a controller, which intervenes in the drive and brake system of the vehicle and regulates the driving speed, possibly as a function of the distance to the obstacle, in a closed-loop control circuit if the vehicle speed is above a certain limit speed, characterized by a control device, which intervenes in the drive and brake system in a controlling manner at driving speeds below the limit speed.
- A process and device for detecting on an aircraft an overshoot of design loads at the level of a structural part of the aircraft. The detection device includes a speed measuring device for measuring an effective speed of the aircraft. A first comparator compares the measured effective speed with a maximum speed relating to the current flight configuration of the aircraft. A vertical load measuring device measures a vertical load factor of the aircraft, and a second comparator compares the measured vertical load factor with a limit value of the vertical load factor. An inspection determining device determines whether a structural inspection needs to be performed at the level of the structural part, based of the results of the first and second comparisons.
- The invention relates to a method and device for determining the volumetric flow rate of milk flowing during a milking process. A cross-sectional area (Ai) of the milk flow (2) is determined at a first measuring point (3) by means of a sensor (4) which is arranged outside the flowing milk. The time (ti) required by the milk flow (2) with the determined cross-sectional are (Ai), to go from the first measuring point (3) to a second measuring point (5) which is provided downstream from the first measuring point, is measured. The flow speed (vi) is derived from the measured time (ti) and the known distance (s) between the first and second measuring points (3, 5). The volumetric flow rate (V(t)) is determined on the basis of the determined cross-sectional area (Ai) and the flow speed (vi).
