Patent CA-2980567-A1 (CA)
Title: Rotating control device
Inventor: HOYER CAREL W
IPC: E21B47/06
Filed: 2010-07-27
Abstract: 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.

Patent CA-3009274-A1 (CA)
Inventor: KOPONEN NIILO WILLIAM ALEXANDER
IPC: F02D37/02
Filed: 2018-06-22
Abstract: Unlike similar internal combustion engines that vary the fuel-air mixture, the Augmented Compression Engine (ACE.) first and foremost sets and maintains an optimal stoichiometric fuel to air ratio, relying upon various implementations of Boyle's law to attain ignition of the stoichiometric fuel-air mixture in the combustion chamber while varying quantities of the fuel-air mixture to adjust output power. An ACE uses fuel-air mixed prior to attainment of auto-ignition temperatures in the combustion chamber, compresses it and achieves ignition by an ignition source or use of compression heating the fuel-air to its auto-ignition temperature. Since different quantities of the fuel-air mix are needed for different loads (power outputs), to maintain reliable ignition the ACE uses one or more of: varying intake pressure valve timing; recycled exhaust or other implementations of Boyle's law for adjusting compression such as, injected matter, modifying fuel or changing of combustion chamber volume.

Abstract: In one embodiment, a method includes sending information to display an image on a screen. A scroll range for the image may be determined based on dimensions of the image. An origin position and an initial tilt of a gyroscope may also be determined for the image. Tilt measurements associated with the presentation of the image may be received as the gyroscope detects changes in tilt. A progress parameter may be determined based on at least the scroll range, the origin position, and the initial tilt. A scrolling presentation of the image may then be rendered based on the progress parameter. The scrolling presentation of the image may be smoothed by applying an RK4 solver to the tilt measurements to eliminate jitter due to hand tremors. A virtual spring effect may also be applied to give the scrolling presentation a bouncy effect as the edge of the image is reached.

Title: Multi-dimensional frequency domain extrapolation of sensor data
Inventor: HARBAUGH J KENT
IPC: G06K9/00
Filed: 2017-07-19
Abstract: Embodiments of a device and a frequency data extrapolator are generally described herein. The frequency data extrapolator may receive input frequency data mapped to a two-dimensional frequency grid. As an example, the input frequency data may be based on return signals received, at a sensor of the device, in response to pulsed transmissions of the sensor in a physical environment. Regions of the frequency grid may be classified as high fidelity or low fidelity. A group of basis rectangles may be determined within the high fidelity regions. A column-wise extrapolation matrix and a row-wise extrapolation matrix may be determined based on the input frequency data of the basis rectangles. The input frequency data of the high fidelity regions may be extrapolated to replace the input frequency data of the low fidelity regions.
