Abstract: 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.

Abstract: An optical device includes a range of angularly selective reflectors are contained within an optical waveguide substrate and substantially optimized according to their reflector order within the sequence of reflectors. This configuration of reflectors ensures that the required angular information is passed through to the correct reflector within the sequence. The angular response in addition reduces or eliminates formation of secondary images carried to successive reflectors, resulting in undesired artefacts.

Abstract: 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.
