20140138094 | System and Method for Cooling a Rotating Control Device. - A Drill-To-The-Limit (DTTL) drilling method variant to Managed Pressure Drilling (MPD) applies constant surface backpressure, whether the mud is circulating (choke valve open) or not (choke valve closed). Because of the constant application of surface backpressure, the DTTL method can use lighter mud weight that still has the cutting carrying ability to keep the borehole clean. The DTTL method identifies the weakest component of the pressure containment system, such as the fracture pressure of the formation or the casing shoe leak off test (LOT). With a higher pressure rated RCD, such as 5,000 psi (34,474 kPa) dynamic or working pressure and 10,000 psi (68,948 kPa) static pressure, the limitation will generally be the fracture pressure of the formation or the LOT. In the DTTL method, since surface backpressure is constantly applied, the pore pressure limitation of the conventional drilling window can be disregarded in developing the fluid and drilling programs. Using the DTTL method a deeper wellbore can be drilled with larger resulting end tubulars, such as casings and production liners, than had been capable with conventional MPD applications. | 05-22-2014 |

Methods illustratively include obtaining first and second images covering a wide field-of-view. The second image is registered to and compared to the first image. Based at least in part on the comparison, a moving object within the wide field-of-view is detected. An indication of the moving object is provided. | 03-25-2010 |
20110169867 | MOVING OBJECT DETECTION, TRACKING, AND DISPLAYING SYSTEMS - Moving object detecting, tracking, and displaying systems are provided. Systems illustratively include a graphical user interface and a processing unit. The processing unit is a functional part of the system that executes computer readable instructions to generate the graphical user interface. The graphical user interface may include an alert and tracking window that has a first dimension that corresponds to a temporal domain and a second dimension that corresponds to a spatial domain. In some embodiments, alert and tracking windows include target tracking markers. Target tracking markers optionally provide information about moving objects such as, but not limited to, information about past locations of moving objects and information about sizes of moving objects. Certain embodiments may also include other features such as zoom windows, playback controls, and graphical imagery added to a display to highlight moving objects. | 07-14-2011 |
20120120189 | SYSTEM FOR EXTENDING A FIELD-OF-VIEW OF AN IMAGE ACQUISITION DEVICE - Systems for extending a field-of-view of an image acquisition device are provided. In one embodiment, a system includes a rotatable image-directing device, an actuator, and a controller. The rotatable image-directing device directs optical images along an optical image path. The actuator controls a position of the rotatable image-directing device, and the controller generates signals for synchronizing the rotatable image-directing device and the image acquisition device. The signals illustratively include a first signal that is transmitted to the actuator, and a second signal that is transmitted to the image acquisition device. | 05-17-2012 |
