Standard loop detector controller cards sample traffic at a rate of 60Hz. However, they frequently do not push detailed information back to the traffic management center (TMC). Instead, they calculate and then aggregate values such as volumes and occupancies at up to 30-second intervals before sending this data back to the central processing system. Past approaches to loop-based vehicle re-iden ...

We propose here to evaluate a variety of inorganic scintillators, including sodium iodide and bismuth germanate, for use in energy-sensitive neutron detectors. We will couple these crystals to photomultiplier tubes and measure the prompt response to inelastic neutron reactions with the scintillator atoms. To unfold the incident neutron energy distribution from the resulting signal pulse heights, ...

The Rail Yard Automated Helper (RYAH) features an eight joint robotic arm integrated with a hydrostatic drive mobility unit. The unit can be tele-operated in a manned, computer aided mode. The RYAH increases rail yard worker safety by determining exposure to physical activities that result in injury such as slipping, falling, over-exertion and entrapment. The system controller provides: 1) A r ...

The proposed system will provide a very robust means of determining that the driver of a moving vehicle is attempting to use his phone for a purpose restricted by local regulations. The system will then preclude the restricted operation. Cell phone usage that is not restricted by local regulations will not be affected. The system imposes no changes to public roadways or to the vehicles used to ...

PARAMETRIC X-RADIATION (PXR) IS PROPOSED AS AN INTENSE, TUNABLE, MONOCHROMATIC HARD-X-RAY SOURCE FOR THE DETECTION OF EXPLOSIVES. THIS RADIATION IS HIGHLY COLLIMATED, HAS A BANDWIDTH OF 0.1, AND AN INTENSITY EQUAL TO THAT OF SYNCHROTRON RADIATION ON A PER ELECTRON BASIS. PXR GENERATION IS ACHIEVED BY PLACING CRYSTALS INTO THE PATH OF ELECTRON BEAMS WITH ENERGY OF 6 MEV OR GREATER. THE VIRTUAL PHOT ...

The National Highway Traffic Safety Administration reports year over year increases in motorcycle fatalities and accidents over the past ten years. Of these: · 2/3s of the deaths were related to excessive speed and loss of operator control · 60% of deaths occurred at night or with poor visibility · Approximately 30% were not properly licensed · A majority had e ...
