  • Patent number: 7764197
    Abstract: A method and system for synchronization of detection loops in a multilane environment. A plurality of loop sensors are arranged in a plurality of lanes such that loop sensors in adjacent lanes are mutually contiguous. A simultaneous synchronization signal is sent to each of the plurality of loop detector controllers, where each loop detector controller is in communication with a loop sensor. The signal causes a scheduling of sampling periods for each loop sensor, such that the sampling period of each loop sensor does not overlap with that of a contiguous loop in an adjacent lane.
    Type: Grant

  • Patent number: 7071840
    Abstract: A ferromagnetic loop having a footprint characterized by a continuous wire shaped in a serpentine manner to form multiple contiguous polygons within the footprint for detection of moving vehicles. The footprint can be one of a triangle, a square, a rectangle, a rhombus, a parallelogram, an ellipse, or a circle. Similarly, each of the multiple contiguous polygons can be one of a triangle, a square, a rectangle, a rhombus, a parallelogram. Different design configurations for the ferromagnetic loop and methods for making and using the same are disclosed.

  • Patent number: 6752254
    Abstract: An automatic coin machine having a redundant coin processing system with at least two coin processing mechanisms. The first or the active coin processing mechanism is initially set up to receive coins from a coin diverter which is in communication with a coin collection device. While the active coin processing mechanism is processing the coins received from the coin diverter, the inactive or the second coin processing mechanism can be serviced without affecting operation of the active coin processing mechanism. When the first coin processing mechanism becomes disabled, in need of service, or is otherwise idle, the coin diverter is switched from the first coin processing mechanism to the second coin processing mechanism, thus making the first coin processing mechanism inactive, and at the same time, making the second processing mechanism active.
