20150285046 | Chemical Injection To Increase Production From Gas Wells - There is described a chemical injection system for a natural gas well. An instrument monitors the production of gas from the well and the flow of chemicals injected into the well. The instrument controls the on and off time of a chemical injection pump that is attached to a chemical injection tank. The control is based for certain chemicals such as a surfactant on the gas flow rate in the production piping. The user of the system inserts in the instrument the setpoints associated with the well's flow rate. These setpoints determine for a given flow rate the on time for the chemical injection pump. Other chemicals can also be injected into the well using the system and the injection for those chemicals may be based on other criteria such as temperature, water rate, oil rate or pipeline flow rate. | 10-08-2015 |

20140181126 | System and Method for Scheduling and Arbitrating Events in Computing and Networking - A method for high-speed scheduling and arbitration of events for computing and networking is disclosed. The method includes the software and hardware implementation of a unique data structure, known as a pile, for scheduling and arbitration of events. According to the method, events are stored in loosely sorted order in piles, with the next event to be processed residing in the root node of the pile. The pipelining of the insertion and removal of events from the piles allows for simultaneous event removal and next event calculation. The method's inherent parallelisms thus allow for the automatic rescheduling of removed events for re-execution at a future time, also known as event swapping. The method executes in O(1) time. | 06-26-2014 |

20140076053 | PROFILING TOOL FOR DETERMINING MATERIAL THICKNESS FOR INSPECTION SITES HAVING COMPLEX TOPOGRAPHY - A phased array ultrasonic probe may be mounted to a component to be inspected for wall thickness on an apparatus that includes a split ring adapted to be magnetically held in place on the component. In particular, the probe may be mounted to a carriage connected to the split ring in a manner that allows the carriage to rotate around the split ring while the probe is in operation. Between the probe and the component, a transducer shoe defining, by a flexible membrane, a cavity and an aperture. Conveniently, the construction of the flexible membrane allows wall thickness measurements to be acquired in portions of the component that have complex topography, such as welds. The apparatus is installed on an adaptor assembly for inspection of straight section of pipes. This adaptor assembly is not used in absence of straight section. By acquiring data from multiple output pulse transmitted at multiple incidence angles, processing software may conveniently produce an accurate wall thickness map of the area of interest on the component. | 03-20-2014 |

20120239209 | MULTIPURPOSE CONTROLLER FOR MULTISTATE WINDOWS - “Smart” controllers for windows having controllable optical transitions are described. Controllers with multiple features can sense and adapt to local environmental conditions. Controllers described herein can be integrated with a building management system (BMS) to greatly enhance the BMS's effectiveness at managing local environments in a building. The controllers may have one, two, three or more functions such as powering a smart window, determining the percent transmittance, size, and/or temperature of a smart window, providing wireless communication between the controller and a separate communication node, etc. | 09-20-2012 |
20120293855 | ONBOARD CONTROLLER FOR MULTISTATE WINDOWS - Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations. | 11-22-2012 |
