| 20120068882 | Antennas - An active antenna array is arranged to activate subsets of switchable elements causing the antenna to form a first beam having a first beam pattern, and later to form a second beam having a second beam pattern of substantially identical far field radiation pattern to the first beam pattern but with different origins. A receiver receives radiation reflected from a target back to the antenna when the antenna is configured with the first beam pattern and then when configured with the second beam pattern, and compares the phase of the radiation received at the receiver when the antenna is configured with the first beam pattern with the phase of the radiation received at the receiver when the antenna is configured with the second beam pattern to provide a phase difference signal. A target locating means determines the angular location of the target from the phase difference signal. | 03-22-2012 |

| 20110148401 | DEVICE FOR LOCATING WHETHER A WHEEL-TIRE ASSEMBLY IS POSITIONED ON THE RIGHT OR THE LEFT OF A VEHICLE - A self-contained device intended to be carried by a wheel-tire assembly in order to locate whether the assembly is positioned on the right side or on the left side of a vehicle is described. The device includes two magnetic sensors with axes of maximum sensitivity, the sensors providing two periodic signals that are phase shifted relative to one another. Each signal is representative of variations in the magnitude of the magnetic field detected by the sensor during a revolution of the wheel-tire assembly. The device also includes a processing unit programmed to determine, from the phase shift between the two periodic signals, a direction in which the wheel-tire assembly is rotating and to deduce, from this direction of rotation and from a direction of travel of the vehicle, whether the wheel-tire assembly is located on the right side or on the left side. The two magnetic sensors are intended to be positioned on the wheel-tire assembly at distinct azimuthal locations. A filtering element of the device is designed to eliminate components of the two periodic signals having frequencies that are below or equal to a given frequency. | 06-23-2011 |
