Abstract: A system for managing an access to an asset is provided. A digital key to the asset is generated and synchronized between a first user device of a first user and an access control device that controls the access to the asset. A key-sharing request is initiated by the first user device to grant a second user the access to the asset. Based on the key-sharing request, an application server communicates the digital key to a second user device of the second user. When the second user device is within a detection range of the access control device, the access control device receives the digital key from the second user device, validates the digital key, and grants the second user the access to the asset for an access duration defined in the key-sharing request.

Abstract: A method for facilitating charge transfer is provided. The method includes receiving, via an electronic device, a request to transfer charge stored in an energy storage device. The method includes determining a set of parameters of the energy storage device based on the received request. The set of parameters includes an amount of charge determined to be transferred from the energy storage device or a charge level desired to be achieved for the energy storage device. The method includes identifying charging systems available to receive and store charge corresponding to the set of parameters of the energy storage device. The method further includes allocating one of the identified charging systems to receive charge from the energy storage device and store the received amount of charge. The allocated charging system travels to a location of the energy storage device to receive the determined amount of charge from the energy storage device.

Abstract: An aircraft door controller 100 including a receiver 110 configured to receive a command 14 to move an aircraft door between an open position and a closed position relative to a door frame. The aircraft door controller 100 is configured to not store the command 14 when power to move the aircraft door between the open position and the closed position relative to the door frame is unavailable.

Abstract: A method for facilitating charging is provided. The method includes receiving a charging request from a user device for charging an energy storage device associated with an acceptor node. The method includes determining a set of charging parameters for the energy storage device based on the charging request. The method includes identifying one or more mobile charging systems that are available within a first geographical region associated with the acceptor node and satisfy the set of charging parameters. The method includes allocating, from the one or more mobile charging systems, a first mobile charging system to charge the energy storage device of the acceptor node. Based on the allocation, the first mobile charging system travels from a first location to reach a second location of the acceptor node to charge the energy storage device.

Abstract: A control system has first and second processing modules for controlling retraction and extension of an aircraft landing gear assembly. The processing modules operate independently providing redundancy. Each processing module is configured to perform a first sequence of steps for retracting the landing gear assembly and a second sequence of steps for extending the landing gear assembly. A step of switching control from one processing module to the other (e.g. an avionics side changeover step) is performed (a) as part of the first sequence of steps, but only after the landing gear assembly has been retracted, or (b) as part of the second sequence of steps. By ensuring that the step of switching control is performed at such times, and not for example between initiation of the first sequence of steps and the retraction of the landing gear assembly, the landing gear assembly may be retracted sooner after such initiation.

Abstract: A system for dynamic underbalanced perforation of a hydrocarbon well includes a perforation fluid located within the hydrocarbon well. A perforation gun is suspended within the perforation fluid and a completion fluid is located within the hydrocarbon uphole of the perforation fluid. An isolation fluid is located within the hydrocarbon well uphole of the perforation fluid and downhole of the completion fluid. A method of perforating a hydrocarbon well includes a perforation fluid placed in the hydrocarbon well. A perforation gun is placed within the perforation fluid. A completion fluid is placed in the hydrocarbon well. An isolation fluid is placed in the hydrocarbon well. A local dynamic underbalance condition is created in the hydrocarbon well. A flow of the completion fluid downhole is inhibited.

Abstract: The invention provides a method for perforating a well with a perforating fluid comprising a viscoelastic surfactant that essentially stops fluid leak-off after perforation in an overbalanced condition. Another aspect of the invention provides the perforating fluid in itself. The well has a wellbore defined by a generally cylindrical casing in at least a portion of the wellbore (i.e., the wellbore is cased, although it is not necessary cased in its entire length). The wellbore passes through a subterranean formation that comprises hydrocarbon formation fluids (such as oil and/or gas), at least in certain strata. The method comprises placing a perforating device in a wellbore which includes at least one explosive perforating charge that can be detonated in order to perforate the casing and allow the formation fluids to enter the wellbore. The casing is located between the subterranean formation and the perforating device.

Abstract: A dispensing container for a plurality of like flat, thin products disposed in stacked relationship within the container and including a tear-away closure tab whose removal results in an opening through a front panel of the container through which the level of products within the container may be observed and individual ones of the products may be removed from the container. The opening is defined by a unique plurality of perforations and cuts through the thickness of the front panel of the container and has a profile resembling an inverted funnel. A blank for making the carton from a single sheet of material is disclosed.
