Abstract: A method and system for performing dynamic provisioning of augmented reality information is provided. The method includes acquiring, from a user device of a user, user device-based information, retrieving rebate information corresponding to the user device-based information, and retrieving user information of the user of the user device. Based on the acquired and retrieved information, the method further tracks movement or activity of the user device, and determines whether a predetermined condition is met. When the predetermined condition is determined to have been met, the method displays one or more rebates in augmented reality over image information displayed on a display of the user device. However, when the predetermined condition is determined not to have been met, the method continues the tracking of movement or activity of the user device until the predetermined condition is determined to be met.

Abstract: The present disclosure is for an inverted diffuser usable in wellheads and other wellsite equipment. The inverted diffuser includes at least one first section having a first vertical inner surface, a first inclined inner surface relative to the first vertical inner surface, and one or more channels supporting one or more releasable fasteners between the at least one first section and a wall of a wellhead or of a wellsite equipment. At least one second section is press-fitted or fastened adjacent to the at least one first section. A method for application of the inverted diffuser in a wellhead and in other wellsite equipment is also disclosed, along with a method of manufacture of the inverted diffuser.

Abstract: Photonic switch working in Momentum-Division-Multiple-Access (MDMA) mode for microwave and optical wavelengths based upon the measurement of the spin, orbital angular momentum and total angular momentum of the involved photons. For the optical wavelengths Dove prisms and holograms are used in form of a Mach-Zehnder-Interferometer as selectors; for the microwave wavelengths phased-array antennas with double orthogonal dipoles act as selectors.
