20120306649 | AIR TRAFFIC CONTROLLER ALERTING SYSTEM - A monitoring and alerting system for installation in an air traffic control facility. The alerting system monitors the outgoing transmissions from the control facility to secondary locations, the responsiveness of the control facility personnel to aircraft communications or both. The monitoring and alerting system utilizes multiple stages of alerts for the air traffic controllers. In a first stage, a light source is displayed within the control facility. In a second stage, an audible noise is sounded within the control facility. In a third stage, an audible noise of increased volume is sounded in or near the control facility, a notice is sent to command and control and/or an indication is sent to a Central Control Facility. The three stages of alerts are progressively activated if the personnel in the control facility fail to adequately utilize connected equipment monitored by the alerting system within predetermined time periods. | 12-06-2012 |

20130140270 | IC-PROCESSED POLYMER NANO-LIQUID CHROMATOGRAPHY SYSTEM ON-A-CHIP AND METHOD OF MAKING IT - Embodiments in accordance with the present invention relate to packed-column nano-liquid chromatography (nano-LC) systems integrated on-chip, and methods for producing and using same. The microfabricated chip includes a column, flits/filters, an injector, and a detector, fabricated in a process compatible with those conventionally utilized to form integrated circuits. The column can be packed with supports for various different stationary phases to allow performance of different forms of nano-LC, including but not limited to reversed-phase, normal-phase, adsorption, size-exclusion, affinity, and ion chromatography. A cross-channel injector injects a nanolitre/picolitre-volume sample plug at the column inlet. An electrochemical/conductivity sensor integrated at the column outlet measures separation signals. A self-aligned channel-strengthening technique increases pressure rating of the microfluidic system, allowing it to withstand the high pressure normally used in high performance liquid chromatography (HPLC). On-chip sample injection, separation, and detection of mixture of anions in water is successfully demonstrated using ion-exchange nano-LC. | 06-06-2013 |

20120330466 | OPERATIONAL LOGIC FOR PRESSURE CONTROL OF A WELLHEAD - Methods and apparatus are provided for controlling production from a well by monitoring a parameter at a wellhead and adjusting a choke in an effort to maintain a desired parameter (e.g., a tubing head pressure (THP), bottom home pressure (BHP), a flow rate, or water cut (WC)). For some embodiments, a time window may be used for calculating a running average of parameter samples, and a proportional-integral-derivative (PID) control loop may be utilized to determine the difference between the running average and a parameter setpoint and to output a signal based on the difference to adjust the choke opening accordingly. In this manner, control of production from an individual well may be more accurate and reliable. Furthermore, for multiple wells coupled to a gathering center, maintaining a constant parameter for each of the multiple wells may enable stable operation of a gathering system and desired hydrocarbon production from each of the wells. | 12-27-2012 |
