Guidance system for public transport vehicle

Abstract: The guidance system makes use of coded markings (16) that are detected optically. The markings are on the roadway. The markings are read and analysed by a device fitted to the vehicle. The vehicle is also fitted with lateral arms that displace the steering wheels of the vehicle if the arms make contact with a lateral guide wall (18,20). The vehicle can be operated with one or both modes of guidance depending allowing use of the more suitable mode at different points of the route.

Infrared-optical multisensor for autonomous landing guidance

Abstract: Infrared sensors at the nominal 8 - 12 and 3 - 5 micron wavebands respectively can be shown to have complementary performance characteristics when used over a range of meteorological conditions. The infrared/optical multisensor for the autonomous landing guidance system integrates staring longwave, midwave, and visible sensors into an environmentally sealed and purged assembly. The infrared modules include specific enhancements for the detection of runways under adverse weather conditions. The sensors incorporate pixel-for-pixel overlap registration, and the fields of view match a conformal head-up display with sensor/display boresighting to within a fraction of a pixel. Tower tests will be used to characterize the sensors and gather data to support simulation and image processing efforts. After integration with other elements of the autonomous landing guidance system, flight tests will be conducted on Air Force and commercial transport aircraft. In addition to display and analog video recording, the multisensor data will be digitally captured during critical flight test phases.

Improving performance on procedural tasks through presentation of locational procedure context: an empirical evaluation

Abstract: Procedures in some form are used in almost all work domains to guide and define work. Using new small electronic devices, task guidance systems can be developed that change how workers follow and use procedures. The capability of task guidance systems to store large amounts of information in a small physical space allows for a single system to provide guidance for various tasks in a mobile environment. However, task guidance systems often have small information displays. Preliminary studies have shown that this drawback can impede task performance by causing a blind adherence to the presented procedures. To mitigate this effect, we examined the impact of presenting locational procedure context, in order to portray procedure steps within the larger organization of the procedure. The study examined the relationship between locational procedure context and task performance for the task of preflight inspection of a general aviation aircraft using wearable-computer task guidance systems. Results of the study suggest that the presentation of locational procedure context improves inspection performance by one measure but was not effective for another measure, and also provides some evidence that the medium on which a procedure is presented is not a factor in performance.

Real-time simulation platform for airport activity area monitoring guidance system

Abstract: The invention discloses a real-time simulation platform for an airport activity area monitoring guidance system. The real-time simulation platform comprises an airport activity area multisensory target simulation system, a flight attitude calculation and data conversion module, a simulation cockpit seat, a recording and playback module, a three-dimensional scene generation platform, a computer cluster graphic processing system and a large screen high definition projected display system. Data of the airport activity area multisensory target simulation system are processed through the airport activity area monitoring guidance system and then output to the flight attitude calculation and data conversion module for flight attitude calculation and format conversion, graph segmentation is carried out through simulation of the three-dimensional scene generation platform and the computer cluster graphic processing system, and ultimately the data are displayed through the large screen high definition projected display system. The real-time simulation platform can meet the simulation requirements of multiple airport activity area monitoring systems, seamless splice pictures are displayed with high definition, and the simulation degree is high.
