Abstract: A multipurpose sensing system of detecting, qualifying and quantifying a potential threat to national security comprises a multipurpose sensing module associated with each cargo carrying container. The system tracks the instantaneous location of each cargo carrying container with the multipurpose sensing module on board each cargo carrying container sampling the contents thereof for the presence of material selected from the group comprising nuclear, biological and chemical grade weapons material.

Abstract: A system of identifying, classifying quantifying, notifying and neutralizing an environmental hazard comprises a field deployable marker and a remote receiving station. The field deployable marker carries a means for identifying, a means for classifying and a means for quantifying any environmental hazard. A means for notifying the remote receiving station and a means for neutralizing the identified environmental hazard are also carried by the field deployable marker wherein the means for notifying transmits data to the remote receiving station.

Abstract: A multiple hazard marker system consists of at least one multiple hazard marker, a deployment vehicle, a deployment surface and a deployment device for deploying the multiple hazard marker. The multiple hazard marker comprises a ground engaging portion, an upper portion and a central portion. The multiple hazard marker will remain erect when deployed and includes a visible marker for marking a position upon a field where deployed. The multiple hazard marker further has collapsible elements that expand upon deployment, a signaling device, a receiver for activating the signaling device and transmitter associated with the signaling device.

Abstract: An electronic eye depth testing method comprises a three dimensional cubic space displayed on a display screen, wherein the cubic space has a first image of a three dimensional object and a second image of a three dimensional object randomly placed within the cubic space. The first image is located at the intersection of two perpendicular horizontal planes and a vertical plane perpendicular to said two horizontal planes and the second image is located at the intersection of two perpendicular horizontal planes and a vertical plane perpendicular to said two horizontal planes. A subject to be tested for depth perception is directed to move the images into convergence in the center of the cubic space.

Abstract: A computer program for an eye depth perception test method comprises a personal data entry form for recording statistical information of a subject to be tested in a personal data step of the program where the statistical information keyed is to a specific personal identification number. The computer program further comprises an algorithm to draw a cubic space upon a display screen in a display step, the algorithm drawing a first image at a first random location within the cubic space and a second image at a second random location within the cubic space in an image selection step, the program then permitting the subject to be tested for depth perception to move the first image and the second image toward convergence in the center of the cubic space.

Abstract: A method for quantitatively and objectively measuring the usability of a system. The method provides quantitative measures for usability satisfaction, usability performance, and usability performance indicators. Usability satisfaction is measured by acquiring data from a system user population with respect to a set of critical factors that are identified for the system. Usability performance is measured by acquiring data for quantifying the statistical significance of the difference in the mean time for an Expert population to perform a task on a particular number of trials and the estimated mean time for a Novice population to perform the task on the same number of trials. The estimated mean time is calculated according to the Power Law of Practice.

Abstract: An improved, and more objective, eye depth perception testing apparatus wherein the eyes of a patient are tested by observing test specimens, posts or pegs of varying colors, varying shapes, varying lateral spacings, and at different lighting conditions. The apparatus, in its preferred aspects embodies a housing upon a floor or ceiling of which is provided parallel tracks within which is mounted a pair of carriers which carry transverse holders which carry a pair of pegs the lateral spacing of which can be adjusted to different widths. These pegs, the movement of which is controlled by the patient, being tested, are exchangeable, vary in color and cross-sectional shape. The walls of the apparatus are mirrored, and the inside of the apparatus is provided with a source of light which can be varied over a range of illuminations of varying intensity. The mirrors disperse the light, and eliminate reference sources, or points, this creating greater objectivity in the testing.
