  • Patent number: 9836969
    Abstract: A system and method are provided for connecting intersections, to enable two-way wireless communication between a cloud-based traffic operations service and new and existing traffic cabinet hardware using “connected intersection” technology. By providing hardware in existing (or new) traffic control cabinets that can communicate wirelessly with a cloud-based traffic operations system, customers can enhance and upgrade legacy traffic networks using existing IT infrastructure (i.e. servers, hard drives, etc.) or existing communication networks. The connected intersection technology further provides software functionalities including real-time alerts, connectivity between existing cabinets and central systems, and signal timing-plan management for customers that lack an existing central system.

  • Patent number: 7308944
    Abstract: The present invention generally relates to apparatus and methods for expanding a tubular. In one embodiment, an expander tool includes a body having at least one recess therein. An expansion assembly disposable in the at least one recess includes a piston that outwardly extends from the body in response to a radially outward force. The expansion assembly includes one or more rollers disposed on a shaft such that the rollers rotate at different speeds. In order to improve a rolling ratio, the shaft is arranged on the piston at an outward angle relative to a longitudinal axis of the tool. The expansion assembly is disposed along the tool at a skew to provide tractoring and reduce slippage due to axial movement. A bearing adjacent the roller and rotationally secured to the roller reduces roller heating and wear. In another aspect, methods for expanding a tubular within a wellbore are provided.

  • Publication number: 20070000664
    Abstract: Methods and apparatus for expanding a tubular with the aid of a compressive force are disclosed. A tubular is run into a wellbore. While the tubular is in a compressive state, the tubular is expanded into its desired form. The expanded tubular can be used for multiple downhole functions such as completing multilateral junctions in a wellbore, patching apertures in a wellbore and lining a wellbore.

  • Publication number: 20050023001
    Abstract: This invention relates to expanding tubing, and in particular to expansion of tubing downhole. Embodiments of the invention relate to anchoring and expanding tubing downhole. In one embodiment, a method of expanding tubing such as a section of casing (10) is disclosed, the method comprising the steps of locating the casing (10) in a bore (12), expanding a portion of the casing (10) to engage the bore wall using an expansion tool (16) having at least one radially movable expansion member, in the form of a roller (24) of a rotary expander (20), and then expanding a further portion of the casing (10) by advancing a cone expander (22) through the casing (10).

  • Patent number: 5793931
    Abstract: A method and apparatus wherein a Genetic Algorithm or an Evolutionary Program is used as an intelligent search technique addresses the problem of assigning sensor reports in multi-target tracking with one or more sensors. The inventive technique of tracking objects includes receiving sensor reports from at least one sensor over multiple time scans; formulating hypotheses as lists of associations between the sensor reports; constructing at least one track for each of the hypotheses; scoring each of the hypotheses; searching through a portion of the hypotheses, using an intelligent search algorithm, to find a good hypothesis; and determining the state of the tracked objects.
