Abstract:
A system (10) for operator training and evaluation may detect and record information about various actions taken by an operator. For example, the system may record (70) what the operator looks at in the course of operating the vehicle to determine whether the operator is looking at the things which the operator should appropriately be checking. In addition the system may provide other information (80, 82) about other aspects of the operator's performance including speed and use of controls and indicators. This information may be correlated and provided in the form of an evaluation. Alternatively, the operator may be prompted (76) in the course of operating the vehicle to correct the operator's performance to improve the operator's skill.
Abstract:
A vehicle simulation system has an image system for projecting a simulated out-the-window scene and symbology as produced by a head-up display onto a viewing screen. A dummy beamsplitting or combiner structure is positioned so that the user can view the scene with the head-up display symbology through it. A filtering structure is provided on the combiner structure to prevent the user from viewing the head-up display symbology outside the combiner structure.
Abstract:
Disclosed herewith is a simulation game apparatus for motor racing. The simulation game apparatus functions and is operated in the same manner as an actual racing car functions and is operated owing to the same interior structure and shape as those of an actual racing car, which allows a player to sit in an apparatus, and which provides feelings sensed during actual driving according to the degree of the rotation of a steering wheel, the degree of braking and acceleration and accidents to a player, thereby allowing a player to learn the skills of motor racing while sensing the feeling of an actual motor race and to enjoy motor races similar to actual motor races even in a small space. Accordingly, motor racing can be enjoyed economically and by a lot of people.
Abstract:
A reconfigurable hardware interface for driving simulators that uses a filed programmable gate array (508) for interfacing with driving controls and instruments. The field programmable gate array (508) in interposed between the input/output of the computer system (501) of the driving simulator and vehicle cab (509) of the driving simulator. This provides convenience in quickly adapting a driving simulator to a particular type of cab (509) and controls, as well as other functions.
Abstract:
The invention relates to a device for creating an image (1) for a front view by means of an incident projection, in particular for image display in a training station, in a simulator, or in an adventure world, by means of a projector (2, 3). Said device is characterised, whereby one or several projectors (2, 3) project the image of a normal view, onto a projection plane (6) within a projection dome, by means of a refracted, brightness- and/or colour-modulated light beam emanating from a point of origin, in the form of individual lines and images. Said projectors (2, 3) are arranged in a position, such that the point of origin of the projection beams lies in front of the front plane of a participating person (7).
Abstract:
A wide-angle display system having an image projector, an image generator, and a plurality of CRT assemblies (200). Each CRT assembly includes a CRT member, an adapter housing (206), and a lens assembly. Each CRT member includes a CRT, a CRT cooling element (208), and a CRT housing for coupling to the image projector. The adapter housing has a first surface, and a second surface that forms a selected dihedral angle with the first surface. In an alternate embodiment, an adapter plate is disposed between the adapter housing and the lens assembly. The adapter plate has a first surface, and a second surface that forms the selected dihedral angle with the first surface. The selected dihedral angle between the adapter housing and the lens assembly causes a longitudinal axis of the CRT member to be offset from a longitudinal axis of the lens assembly, thereby correcting image distortion, such as Scheimpflug distortions.
Abstract:
A three-dimensional simulator which can form a high quality image on a real time basis even when a large number of display objects gather in the vicinity of a visual point. An object image information memory section (212) stores a plurality of kinds of object image information including the number of different polygons (preciseness). First setting means (120) sets the preciseness in such a manner that the smaller the range of a serial number in which the serial numbers of display objects lie, the higher becomes the preciseness of the display objects. Second setting means (122) sets the preciseness in such a manner that the smaller the range of the distance in which the display objects are positioned, the higher becomes the preciseness of the display objects. The setting of the second setting means (122) is changed by the result of setting by the first setting means (120).
Abstract:
The invention relates to an aqueous suspension of precipitation silica, characterized in that its concentration of dry material is comprised between 10 and 40 % by weight, its viscosity is lower than 4.10 Pa.s for a shearing of 50 s and the quantity of silica contained in the supernatant obtained after centrifugation of said suspension at 7500 rpm during 30 minutes represents more than 50 % of the weight of silica contained in the suspension. The grain size distribution of suspended agglomerates is such that their medium diameter D50 is smaller than 5 mu m and the disagglomeration factor FD is higher than 3 ml. Said suspension may be used for producing anti-corrosion coatings, for the preparation of concretes, paper or mineral glues.
Abstract:
A vehicle simulator including a system for development of vehicle simulation scenarios. The vehicle simulation system includes simulated vehicle controls providing input signals to a computer, and feedback devices, including a video display, providing a user with feedback on the operation and location of the simulated vehicle as it is driven through a simulated universe. One aspect of the invention is a scenario development system which uses the vehicle controls, the computer and the output devices to enable a scenario developer to develop a simulation scenario which includes other programmed vehicles. The scenario developer can determine when and where the other programmed vehicles become active in a simulated universe in which the scenario takes place, as well as determine when and where the programmed vehicles leave the simulated universe. The scenario developer can also program the path of the programmed vehicles through the simulated universe by simply driving the programmed vehicles through the simulated universe using the vehicle controls and the feedback devices to define the path that the scenario developer wishes the programmed vehicle to travel.
Abstract:
A driver training system (100) for a user (102) of a simulated vehicle. The system (100) includes input devices (104-112) for controlling the simulated vehicle, a video display (122) having three-dimensional graphics, a computer (114), modeling software for determining position information based on the input devices, atmospheric effects software to simulate time-of-day and weather conditions, realistic operating feedback software for simulating on the input devices the feedback normally experienced with operating the vehicle, and recursive training software to display a previous route (180) through an environment simultaneously with a present route (192) through the environment together with associated performance data (182-188). Another aspect of the recursive training software replays either the previous route (180) or present route (192) and controls one of the input devices (112) to provide ''hands-on'' feedback to the user (102). The user (102) then incrementally and recursively maximizes parameters associated with vehicle operation skill. The preferred embodiment includes a low frequency sound system (800) having a low frequency speaker (830) mounted on an enclosure (828) adjacent to the simulation user's seat (802) through which road feel cues such as hitting an object are transmitted to the user (102) in response to signals received from the computer (114). Another aspect of the invention is a system (900) for simulating the feel to the user (102) of anti-lock brakes on a brake pedal (106) in response to signals received from the computer (114). The driver training system (100) may be embodied as a vehicle simulator.
