  • Patent number: 10612994
    Abstract: A method, system and computer program product for calculating highway and airport pavement deflections. A pavement monitoring system includes a tractor and a semi-trailer, where a rigid horizontal beam is suspended under the semi-trailer. Various sensing elements are attached to the rigid beam, such as laser scanning sensors configured to measure a distance from the laser scanning sensors to the same point on the pavement at two different times, a gyrometer configured to estimate a raw pitch rate, an inertial measurement unit configured to estimate an orientation of the beam and accelerometers configured to measure an acceleration at a same level as corresponding laser scanning sensors. By utilizing these sensing elements, a more accurate pavement deflection is estimated by not relying on indirect measurements. Furthermore, the tractor and semi-trailer of the pavement monitoring system may travel at the velocity of traffic.

  • Patent number: 9972200
    Abstract: A method and system for estimating traffic signals. The method and system can include constructing trajectories of probe vehicles from GPS data emitted by the probe vehicles, estimating traffic signal cycles, combining the estimates, and computing the traffic signal timing by maximizing a scoring function based on the estimates. Estimating traffic signal cycles can be based on transition times of the probe vehicles starting after a traffic signal turns green.

  • Patent number: 7583040
    Abstract: An operating device for an overhead closure which comprises a motor, operatively connected to the closure for opening and closing the closure, and at least one sensor unit mountable either the closure or a support surface bordering the closure. The sensor unit is operable to detect the presence of an obstacle obstructing a travel path of the closure and to generate a signal in response thereto. A control system is in communication with the sensor and with the motor. The control system includes a control unit which receives the signal and provides a sensing feature which stops and/or opens the closure in response to the signal. The control unit deactivates the sensing feature at a selected point prior to an end limit position of the closure. The selected point is determined by the control unit based on a calculated delay characteristic.

  • Patent number: 7481133
    Abstract: An auxiliary operating device for manually operating a normally motor-operated closure between open and closed positions, the device comprising a shaft, a driving member mounted to the shaft and displaceable between an idle position and an operational position wherein the driving member is operatively coupled to the closure. The device further comprises a manual actuator for first displacing the driving member from its idle position to its operational position and then driving the driving member in order to displace the closure. The actuator can be advantageously mounted at either end portions of the shaft irrespectively of the position of the driving member on the shaft.
