Abstract: A wearable visualization device includes a housing, one or more lenses coupled to the housing and configured to display virtual features for visualization by a user of the wearable visualization device, and a cover coupled to the housing and configured to adjust between an extended configuration in which the cover extends over at least a portion of the one or more lenses and a retracted configuration in which the cover does not extend over at least the portion of the one or more lenses. The wearable visualization device also includes a controller and one or more sensors. The controller is configured to receive sensor data from the one or more sensors and to provide control signals to an actuator to adjust the cover between the extended configuration and the retracted configuration based on the sensor data.

Abstract: An apparatus and method for creating axial movement of an inner sliding sleeve member on a tool in a downhole environment. The apparatus has keys which mate in a profile on the inner sliding sleeve member, the keys being held in a carrier on a sleeve around an inner mandrel. The inner mandrel includes stops and a lip which can be slid over the keys to retract them for release from the inner sliding sleeve member. By picking up and shifting down the mandrel relative to the sleeve, the apparatus is cycled to jar up, jar down and release. An exercise tool to release a stuck flow tube of a subsurface safety valve is described.

Abstract: Method and apparatus for creating a fluid communication line in a downhole environment between an annular chamber and a throughbore of a tool. The tubular wall therebetween is provided with circumferentially arranged recesses extending into the wall to provide selected thin-walled sections for perforation by a communication tool. The communication tool has two oppositely arranged punch heads, one aligned with a recess and the other between neighbouring recesses giving an orientationless configuration in operation. An embodiment for creating a fluid communication line through a tubing retrievable safety valve for operation of a wireline retrievable safety valve located therein is described.

Abstract: An attraction system of an amusement park includes a sensor configured to detect an activity of a user in an interactive attraction area. The attraction system also includes a controller including one or more processors. The one or more processors is configured to receive an indication of the activity from the sensor. The one or more processors is also configured to initiate capture of a piece of digital media via the sensor or a separate sensor in response to receiving the indication, and mint a non-fungible token (NFT) associated with the piece of digital media.

Abstract: An impingement apparatus associated with a conveyor includes: (a) a shell supporting an impinger; and (b) a coolant delivery apparatus enclosed by the shell, the coolant delivery apparatus including a gas circulation device for directing a coolant to the impinger; the impinger including: (i) an impingement plate including openings for directing impingement jets toward the conveyor; (ii) at least one non-circular cam in mechanical communication with the at least one conveyor and rotatable when the conveyor is in motion; and (iii) at least one connector in mechanical communication with the at least one cam and the impingement plate, the connector displaceable during rotation of the at least one cam to elevate and lower the impingement plate.

Abstract: A method of reducing a temperature of at least one item including: transporting the at least one item on a moving substrate within an enclosure, the enclosure including at least one impingement apparatus; providing a coolant to at least one of a high pressure zone or a low pressure zone of the enclosure; circulating the coolant through the high and low pressure zones using a variable-speed gas circulation device of the impingement apparatus; directing impingement jets through openings in at least one impinger of the impingement apparatus toward the moving substrate disposed within the low pressure zone; and intermittently performing an operation on the at least one impingement apparatus during said transporting including: (i) reducing a speed of the variable-speed gas circulation device; (ii) vibrating the at least one impinger; and (iii) increasing the speed of the variable-speed gas circulation device.

Abstract: A food freezer includes: a first housing having a first chamber arranged internally within for providing a freezing gas to a food product within the first chamber; a second housing having a second chamber arranged internally within and being in fluid communication with the first chamber for exhausting the freezing gas from the first chamber; an adjustable opening disposed at a common wall between the first chamber and the second chamber for controlling a flow of the freezing gas moving from the first chamber to the second chamber, the adjustable opening disposed to provide a flow path for the flow of the freezing gas to a region of the second chamber for exhaust from said second chamber to an area external to the first housing and second housing; and a pressure curtain comprising the exhaust and disposed at the second chamber to prevent atmosphere from the area external to the first housing and second housing from entering said housings. A related method of exhausting freezing gas is also provided.
