Abstract: The subject matter described herein includes methods and systems for performing physical measurements using radio frequency (RF) signals. According to one embodiment of the present invention, a method is disclosed for determining the distance between a first radio device and a second radio device. The method includes transmitting a radio frequency (RF) signal from the first radio device and receiving the RF signal by the second radio device. The method further includes a determining a carrier frequency of the RF signal and determining a slope of a carrier phase versus the carrier frequency corresponding to a rate of change of the carrier phase with the carrier frequency. The method also includes determining a physical distance between the first radio device and the second radio device based on the slope; wherein the physical distance is proportional to the slope plus an integer ambiguity term and a bias term.

Abstract: A park-aid system for a vehicle includes a forward-viewing color video camera and at least three other color video cameras, with a first one of the three other color video cameras having a field of view at the driver-side of the vehicle and a second one of the three other color video cameras having a field of view at the passenger-side of the vehicle. A video display screen is viewable by a driver of the vehicle. During a parking maneuver of the vehicle, images derived, at least in part, from image data captured by at least the forward-viewing camera are displayed by the video display screen to assist the driver in operating the vehicle. At least one indication may be provided to the driver of the vehicle during the parking maneuver.

Abstract: A geolocation system includes an originator device configured to transmit a first wireless signal to a transponder device. The transponder device is configured to transmit a second wireless signal to the originator device. The system includes at least one observer device configured to receive the first wireless signal from the originator device and receive the second wireless signal from the transponder device. The system also includes a first processor configured to calculate a transactional difference range at the at least one observer device based on the first wireless signal received at the observer device and the second wireless signal received at the observer device. A corrected transactional difference range value may be calculated by subtracting a time-of-flight of the first wireless signal from the originator device to the transponder device from the transactional difference range. A method of performing geolocation using a transactional difference range is also disclosed.

Abstract: The invention provides a process for comminuting coal or other fuel solids in a shear field, and for optionally coating the solids with catalysts for combustion, liquefaction, and or gasification during the milling process. The process further provides for control of water content in the solids may be controlled before, during and after the milling in order to obtain micronized solids with fine hydration layers. The output fuel solids from the process can burn at low temperatures, avoiding emissions of nitrogen oxides, and they also have improved properties for surfactant-free suspension in either water or oil media, as well as for liquefaction and gasification.
