| 20080271907 | SYSTEM AND METHOD FOR LOOP DETECTOR INSTALLATION - A pre-fabricated ferromagnetic loop having a footprint characterized by a continuous wire shaped according to a predetermined planar pattern. In some embodiments, the predetermined planar pattern can be multiple contiguous polygons within a larger footprint used for establishing a sensor for the detection of moving vehicles. The footprint may include one of a triangle, a square, a rectangle, a rhombus, a parallelogram, an ellipse, or a circle, and/or other shapes or configurations. Similarly, each of the multiple contiguous polygons may include one of a triangle, a square, a rectangle, a rhombus, a parallelogram, and/or other shapes or configurations. A loop sensor housing is arranged to enclose a continuous loop sensor wire configured in the predetermined planar pattern. The prefabricated loop sensor is inserted in a groove web pre-cut in a receiving medium to match the predetermined planar pattern. | 11-06-2008 |
| 20090174575 | MULTILANE VEHICLE INFORMATION CAPTURE SYSTEM - A system and method for accurate express tolling of highway vehicles. A multilane tolling system comprises a tolling (MVIC) unit that collects information from tolling subsystems arranged to take various vehicle measurements. Preferably, an intelligent vehicle identification subsystem sends vehicle information to the MVIC unit many times per second. Preferably, a vision tracking system (VTS) communicates with the MVIC unit and sends the latter information about the vehicle position using vision tracking sensors. Preferably, an RF subsystem conducts multiple reads of a transponder on a passing vehicle and forwards the read information to the MVIC unit. Preferably, a vehicle image capture unit (VICU) captures images of the passing vehicle when a camera in the VICU receives a trigger from the MVIC unit. Preferably, a driver alert module is used alert a driver passing through a tolling point as to account balance associated with a silent toll tag or pay by plate system. | 07-09-2009 |

| 20090278014 | Overhead track system for roadways - Equipment for collecting information from vehicles moving through a lane on a roadway is positioned over the roadway using a track structure and a transfer device. The transfer device is adapted to mount and move the equipment between a first location and a second location along the track structure. A mounting structure, such as a gantry, may be used to support the track structure and/or equipment over the lanes on the roadway. A pulley system may be disposed in the track structure to move the transfer device. Also, a displacing device to raise the equipment relative to the track structure when the equipment is being moved along the track may be used. Alternatively, the transfer device may be mounted in an offset configuration to move the equipment between locations without the use of a displacing device. | 11-12-2009 |
| 20100274641 | MULTIPLE RF READ ZONE SYSTEM - A multizone RF read/write system for conducting transactions with vehicles traveling at high speeds. A first RF read zone is created, preferably by use of a first gantry that extends over at least one lane and contains at least one RF source that creates a large powerful RF read zone for reading or reading and writing to a transponder on a passing vehicle. Additional RF read zones arranged in tandem with the first RF read zone are created by at least one additional RF source that is located on an additional gantry extending over at least one lane, or located on the first gantry. Accordingly, multiple RF read zones are created to conduct transactions with passing vehicles. In one aspect, the multiple RF read zones can be used to ensure that tolling transactions with a single vehicle are more likely to be completed and have a higher degree of accuracy. In another aspect, the multiple RF read zones each employ a different RF technology so that multiple types of RF toll tags can be read and written. | 10-28-2010 |
