Filed:

Jan 27, 2000

Appl. No.:

09/492857

Inventors:

Charles Edward Rodgers - Saint Leonard MD
Darrell Froncis Greenlee - Laurel MD

Assignee:

Optimus Corporation - Silver Spring MD

International Classification:

G06F 1900

US Classification:

702150, 701 35, 34081569, 340438

Abstract:

Crash scene measurement, documentation, and analysis is used to determine crash dynamics and causes in order to determine fault, liability, and prevention methods. The device to be patented is a low cost, compact system that significantly enhances the speed and accuracy of crash scene documentation, and it is applicable to aviation, highway, railway, and vessel crashes. The system will use highly accurate, kinematic, Differential Global Positioning System (DGPS) measurements to locate crash scene elements and reference points with a relative measurement error of less than two centimeters (0. 79 in. ). Using a government DGPS reference signal (National DGPS, US Coast Guard) or locating the reference module on a geodetic marker, allows the absolute location of the scene to be determined with an error of between three to five meters. Once the scene is measured, the device automatically develops accurate dimensions, scene drawing, and a standard report of the crash.

Abstract:

A system and method for generating pedestrian alerts are provided. Vehicle operators are provided with alerts regarding potential vehicle-pedestrian collisions and other dangers involving pedestrians. Additionally, pedestrians may be provided with alerts regarding potential dangers, including dangers of vehicle-pedestrian collisions. Mobile devices, which can be carried or worn by pedestrians, respond to activation signals from a vehicular device. The vehicular device receives positional information from each mobile device within transmission range, and determines relative positions of each of the mobile devices with respect to the position of the vehicular device. A determination of the probability of intersection of any mobile device with a warning zone near the vehicular device is calculated and predicted according to pre-determined rules. If the probability of intersection meets or exceeds a pre-determined threshold, an alert is generated.
