Systems and methods allow a user to interact with an augmented reality device. In one implementation, a wearable device for providing a virtual menu to a user includes a display; at least one sensor configured to provide an output indicative of a viewing direction the user; and at least one processing device. The at least one processing device is configured to cause a virtual menu to be shown on the display; monitor a viewing direction of the user based on the output of the at least one sensor; determine, based on the monitored viewing direction, whether the user is looking in a direction of a selectable element of the virtual menu; determine an amount of time that the user looks in the direction of the selectable element; and cause at least one action associated with the selectable element if the amount of time exceeds a predetermined dwell time threshold.

Systems and methods allow a user to interact with an augmented reality device. In one implementation, a wearable device for controlling operation of an on-board component includes a display; at least one sensor configured to provide an output indicative of a viewing direction of a user; and at least one processing device. The at least one processing device is configured to cause at least one graphical icon associated with a control of at least one aspect of the on-board component to be shown on the display; determine, based on the output of the at least one sensor, whether the user is looking in a direction of the at least one graphical icon; and initiate the control of the at least one aspect of the on-board component when the user is determined to be looking in the direction of the at least one graphical icon.

A new class of reagents and method of use of the reagents in the reaction of the reagents with electrophilic compounds. The invention in one embodiment is directed to a method for the formation of an alcohol of the formula (I). The method includes reacting reagent of the formula (II) with an aldehyde of the formula R10CHO to form the alcohol. X3 is one of O and C(R4)(R5). Each of X1 and X2 is independently O or N—R. Each of Ca and Cb is independently an achiral center, an (S) chiral center or an (R) chiral center. Ra and Rb are (i) each independently C1-10 alkyl, C6-10 aryl or C3-9 heteroaryl, or (ii) taken together to form a C3-C4 alkylene chain which together with Ca and Cb forms a 5-membered or 6-membered aliphatic ring. Rc and Rd are each independently hydrogen, C1-10 alkyl, C6-10 aryl or C3-9 heteroaryl. R is C1-10 alkyl, C6-10 aryl or C3-9 heteroaryl. Each of R1, R2, R3, R4, R5 is independently hydrogen, C1-C10 alkyl, C6-10 aryl, C3-9 heteroaryl, C1-10 alkoxy, C6-10 aryloxy, C1-10 dialkylamino, C1-10 alkyl-C6-10 arylamino, C1-10 diarylamino, or halogen. R6 is halogen, hydrogen, C1-10 alkyl, C6-10 aryl, C3-9 heteroaryl, C1-10 alkoxy, C6-10 aryloxy, C1-10 alkyl-C6-10 arylamino, C1-10 diarylamino, OSO2CF3 or SR. R10 may be C1-10 alkyl, C6-10 aryl, or C3-9 heteroaryl.

The present invention relates to a method of regulating the flow rate of formation fluids produced from a determined zone of an underground well whose cased wall is provided with orifices through which said formation fluids can pass, said method consisting in applying a tubular structure along the casing in said zone, which tubular structure prevents the fluids from flowing directly while also preserving a flow path along which the fluids can flow via the annular space outside the tubular structure so as to generate head loss. The invention also relates to a device for implementing said method, which device is essentially constituted by a radially-expandable tubular structure that can be applied against the inside wall of the casing, the structure being provided with means for preserving the flow of the fluids via a path running along the casing and along the structure, in order to generate head loss.

A method and apparatus for unplugging a well or pipe obstructed by a gas hydrates. According to the invention, a moving heating element is applied against one end of the hydrate plug, and is displaced axially in the tube or the pipe towards the other end, so as to cause the plug to melt progressively from one end to the other. Application to the oil industry, in particular in off-shore wells.

Systems and methods allow a user to interact with an augmented reality device. In one implementation, a wearable device establishes a communication path with a user of the wearable device and at least one individual. The wearable device includes a display; at least one sensor configured to provide an output indicative of a viewing direction of the user; and at least one processing device. The at least one processing device is configured to monitor the viewing direction of the user based on the output of the at least one sensor; determine, based on the monitored viewing direction, whether the user is looking in the direction of the at least one individual; and establish the communication path between the user and the at least one individual if the user is determined to be looking in the direction of the at least one individual.

The present invention relates to a device for laying an expansible lining in a conduit. The device may include a patch having an initial diameter less than that of the conduit, and the patch may be configured to deform by radial expansion beyond an elastic limit to an expanded diameter such that it may contact a wall of the conduit. The device may also include an expander tool axially displaceable inside the patch, and the expander tool may be configured to cause the radial expansion of the patch to an expanded diameter. The device may also include a checking member mounted in proximity to the expander tool. A section of the checking member may be calibrated so that the checking member and the expander tool are capable of passing freely inside the patch when the patch is properly expanded, and the checking member and the expander tool are unable to pass inside the patch when the patch is improperly expanded.

Systems and methods for displaying augmented reality (AR) content are disclosed. The AR device may include a display configured to display real-world content overlaid with AR content and at least one sensor configured to provide an output indicative of an orientation, location, or motion of the AR device. The system may also include a processor device configured to: cause the AR content to be shown on the display at an initial location on the display; determine a change in orientation of the AR device based on the output of the at least one sensor; and change a position of the AR content on the display to a second location on the display, wherein the change in position of the AR content from the initial location to the second location is related to the determined change in orientation of the AR device.
