Title: Multi-tool bottom hole assembly with selective tool operation feature
Inventor: DANIEL R HART
IPC: E21B34/06
Filed: 2017-05-04
Abstract: Dual section mills are selectively sequentially operated by locking an actuator for the backup mill as the primary mill has blades extended with internal flow through a housing. When the primary mill is spent the support string is shifted to defeat a lock on an actuation piston for the backup mill so that its blades can extend and continue to mill to finish the job. The blades of the primary mill continue to rotate in the already milled portion of the window as the secondary mill enlarges the window. Another way the secondary mill is actuated is to open access to flow to the secondary mill by removing a pressure barrier such as a valve or a disappearing plug, for example.

Title: Simulated annealing accelerated optimization for real-time drilling
Inventor: Srinath Madasu
IPC: G06N7/00
Filed: 2018-10-15
Abstract: A system and method for controlling a drilling tool inside a wellbore makes use of simulated annealing and Bayesian optimization to determine optimum controllable drilling parameters. In some aspects, a computing device generates sampled exploration points using simulated annealing and runs a Bayesian optimization using a loss function and the exploration points to optimize at least one controllable drilling parameter to achieve a predicted value for a selected drilling parameter. In some examples, the selected drilling parameter is rate-of-penetration (ROP) and in some examples, the controllable drilling parameters include such parameters as rotational speed (RPM) and weight-on-bit (WOB). In some examples, the computing device applies the controllable drilling parameter(s) to the drilling tool to achieve the predicted value for the selected drilling parameter and provide real-time, closed-loop control and automation in drilling.

Title: Dual mode sensing joystick assembly
Inventor: EDMUND O'NEILL
IPC: G05G9/047
Filed: 2020-04-07
Abstract: A joystick assembly includes a joystick, which may have pre-load centering springs to bias the joystick to a neutral position. The joystick has a central free-play zone, a transitional zone surrounding the central free-play zone in which the pre-load centering springs begin to act upon the joystick, and a load zone surrounding the transitional zone in which the pre-load centering springs exert a relatively flat spring rate upon the joystick. An angular position sensor system generates a first signal indicative of a travel angle of the joystick. A force sensor system generates a second signal indicative of a force applied to the joystick. A controller receives the first and second signals and sets start/stop points for control by the joystick approximately synchronously with the joystick moving from the transitional zone to the load zone based upon the second signal. Initial deflection of the centering springs is determined. A torque curve of the centering springs is evaluated.

Title: Shape packing technique
Inventor: JAMES MICHAEL MCBRIDE
IPC: G06F3/12
Filed: 2019-07-31
Abstract: A shape packing technique is introduced that can be applied in various applications such as automated print production. In an example embodiment, items that are to be placed into a target shape are sorted based on size to form item groups that include similarly sized items. Potential blocks including arrangements of one or more items are created from the sorted item groups. A placement solution is then generated by placing the potential blocks in the target shape using a recursive process that avoids redundant placement solutions until all of the potential blocks are placed or no other potential blocks are able to be placed. The placement solution can then be utilized, for example, to control a printer to print multiple images on a substrate and/or to control an automated cutting device to cut the substrate into multiple partitions according to the placement solution.

Title: Method and apparatus for optical sensing
Inventor: MAHMOUD FARHADIROUSHAN
IPC: G01D5/353
Filed: 2016-03-07
Abstract: An optical fibre distributed sensing system comprises an optical fibre deployable in an environment to be sensed. The optical fibre has a single sensing region with reflectors portions distributed on it. The remainder of the fibre between the sensing apparatus and the sensing region is substantially free of sensors. An optical signal source is arranged to input optical pulses into the optical fibre. Sensing apparatus is arranged to detect light from the pulses reflected back along the fibre and to determine parameters (e.g. temperature, vibration, acoustic) that perturb the path length of the fibre in dependence on the reflected light. The source is controlled to produce pulses at a repetition rate dependent on the sum of the transit time in the sensing region plus the transit time for backscatter along the length of the sensing region. A second optical fibre distributed sensing system includes a pulse repetition rate that is increased by a factor equal to a ratio of a length of the remainder portion to a length of the sensing portion, compared with a pulse repetition rate required to provide whole-length fibre sensing.
