Abstract: A system and method for training a pilot to operate an aircraft in sudden-onset reduced-visibility conditions is disclosed. The system includes electrooptic material having an optical transmittance that varies with an electrical signal applied to the material and a power supply to provide the electrical signal to the material. The electrooptic material is disposed to restrict the pilot's visibility outside the aircraft when the electrooptic material is in a low-optical-transmittance state. The system further includes a flight-safety sensor that sets the output of the power supply to correspond to an optical transmittance state of the electrooptic material that does not substantially restrict the pilot's visibility outside the aircraft when flight conditions are deemed unsafe. The method includes reducing the optical transmittance of the material to restrict the pilot's visibility outside the aircraft in a manner unexpected to the pilot at the time of the transmittance reduction.

A thin, fine mesh screen is used to simulate reduced acuity, scintillation and ghosting effects during low light or rapid motion, which occur during use of actual night vision goggles. The objective focus and diopter adjustment are identical to night vision goggles.

Abstract: A translucent shield (20) is provided for covering a self contained breathing apparatus mask faceplate (22) to simulate smoke. The shield consists of a die cut shape of thermoplastic sheet that duplicates the outline of the self contained breathing apparatus mask faceplate. The translucent shield has a light penetration density concentration simulating smoke in various grades or densities replicating, at the least, limited visibility, intermediate visibility and total engulfment. In order to preclude light penetration, the shape of the shield includes a peripheral overlap (32) onto the mask. A method of removably attaching the shield to the self contained breathing apparatus face mask is provided by the use of pressure sensitive tape (36) or hooks and loop tape (38). The invention simulates smoke which visually limits light transmission to a person wearing an apparatus face mask during training exercise procedures for firefighters.

Abstract: In a distributed method of data gathering, connotative meanings of terms are selected from predefined emotional descriptors organized into a plurality of emotional categories. Respective judges select zero or one emotional descriptors from a given category and rate the term for intensity. Each term is evaluated by a plurality of judges for each emotional category. The results are processed to assure that the selected emotional descriptors were not selected by chance. Anomalous results are purged. Statistical analysis is performed to assure that the selected emotional descriptors were not selected by chance. Retained associations become part of the database for the corresponding record. There may be 0, 1 or more connotative associations for any given record. The completed data base is accessed through a computer interface to implement an electronic language reference tool.

Abstract: A roller coaster includes a plurality of ride vehicles that ride along a track. Each vehicle provides seating for at least one passenger. The track is elevated off the ground and includes a variety of hills, curves, loops, rolls, drops, inversions and the like. The vehicles are totally enclosed and preferably designed to represent a space capsule. Sight line controls and a yaw mechanism are used at the load platform to prevent passengers from seeing the other ride vehicles. In addition, the track at the load platform is angled upwards to allow for easy access to the ride vehicles. Portals in the cabin are designed to control sight lines to focus the passengers' attention on show elements that are placed along the track. An on-board audio system enhances the realism of the ride experience. Adjustable restraint systems are provided in each vehicle to keep the passengers in their seats and inside the vehicle during the ride.

Abstract: Firefighter training device for limiting a trainee's vision and simulating firefighting conditions across a trainee's field of view. The device includes a view-limiting simulation mask which is worn by a trainee (e.g., respirator mask, glasses, or goggles). The mask houses a voltage controlled liquid crystal (LC) lens system, either single or multi-layered, which is divided into various individually and electronically controllable segments. Host dyes might be injected into LC materials to produce colors in the lens segments. Pre-programmed and random pattern control of lens segments occludes the trainee's vision and simulates smoke and/or fires. Sound and strobes might be added to simulate explosions and other firefighting conditions. A transmitter, which includes switchable controls, can be used to send control signals to the mask. The training device can effectively be used indoors or outdoors.

Abstract: A night vision goggle aided flight simulation system and technique allows an flight simulator operator wearing night vision goggles to view an approximate simulation of night vision goggle aided flight. A processor generates at least one look-up table of brightness values utilizing database sources including any selected options. A scene generation computer will then generate the scene image with the contrast based on values provided by the look-up table. An image display system displays the scene at light levels with sufficient dynamic range so that approximate simulation of night vision goggle aided flight is achieved. A neutral density filter can be placed over a CRT display if the CRT display as the display system cannot produce sufficient dynamic range.
