Abstract: A mobile software application implementing “live events,” via which a host of the event may sequentially offer one, two, three, four or more items to a plurality of guests in the event (e.g., via auction, via direct purchase, or via a giveaway). The host's device may obtain and transmit a real-time video stream, which is in turn provided to each guest's device in conjunction with real-time information about the item(s) being offered. Particular techniques further assist the host in sequencing two or more items to be offered in the same live event, thereby avoiding delays and cumbersome user interface interactions that might otherwise be involved in initiating the offering of a next item upon concluding an offering of a previous item.

Abstract: In one example, a method includes running a downhole system into a downhole environment that comprises a wellbore, and the downhole system is configured such that a reusable plug of the downhole system is positioned uphole of a perforation gun of the downhole system, then, with the perforation gun, perforating a casing at a stage of the wellbore, and the perforating is performed using a projectile, and the perforating is performed by firing the projectile from a chamber of the perforation gun.

Abstract: Protection for a secure boot procedure can be provided in addition to cryptographic verification of boot firmware associated with the boot procedure. While the boot firmware is being verified and executed at a secure sub-system, an open sub-system can be put into a halt state, during which the open sub-system is prevented from performing the boot procedure. The open sub-system is still prevented from performing the boot procedure even if the boot firmware is verified and/or executed unless the open sub-system is put into the resume state again.

Abstract: Protection for a secure boot procedure can be provided in addition to cryptographic verification of boot firmware associated with the boot procedure. While the boot firmware is being verified, an open sub-system can be placed into a halt state, during which the open sub-system is prevented from performing the boot procedure. The open sub-system can be subsequently placed into a resume state to further perform the boot procedure when the boot firmware is verified. The open sub-system is still prevented from performing the boot procedure even if the boot firmware is verified unless the open sub-system is placed into the resume state again.

The penetrator assembly includes a penetrator, a propellant operably positioned with respect to the penetrator, a primer in operable communication with the propellant, and an electrical conductor configured and arranged to carry electrical power to the primer. The dispenser may be positioned in a downhole location such as a wellbore, and the penetrator assembly may be fired so that the penetrator perforates a casing in the wellbore.

Abstract: Threat management devices and methods.

Abstract: A method can include detecting, by a glitch detector coupled via a connection matrix to a first processing unit, an indication of a glitch on a memory system. The method can include notifying, via the connection matrix, at least a second processing unit of the detected indication of the glitch. The method can include subsequent to notifying at least the second processing unit, transmitting via the at least the second processing unit a glitch confirmation signal.

Abstract: Methods, systems, and devices related to field firmware update (FFU). A first memory of a memory module may receive an encrypted segment of a FW package associated with FFU. A decrypted segment of the FW package may be stored by the first memory. A re-encrypted segment of the FW package may be stored by the first memory. The re-encrypted segment of the FW package may be communicated to a second memory of the memory module.

Abstract: A beverage dispense fount apparatus (1) suitable for dispensing beverages such as beers or ciders with the addition of additives such as sweeteners and flavourings. The apparatus (1) comprises a beverage inlet (2) connectable to a beverage supply; a beverage outlet (3) configured to dispense beverage into a beverage container; a supply line formed between the beverage inlet (2) and the beverage outlet (3); one or more additive containers (13), each removably mounted within the apparatus and each in fluid connection with a separate additive dispensing line (14); a dispensing pump (15) for each additive container (13) to dispense additive through the additive dispensing lines (14); and a controller for controlling dispensing of additives from the fount apparatus (1). The apparatus (1) may comprise a video screen (9) for interactive video display to customers and a touch screen (10) for controlling operation of the apparatus (1).

Abstract: Embodiments are directed to credential management for distributed services. A plurality of mesh agents for an overlay network may be provided such that the overlay network may be employed to provide a secure tunnel between a client and a resource server. If client request that requires user credentials is provided to a mesh agent associated with the resource server, credential instructions may be provided to the mesh agent and the credential instructions may be employed to determine credential information that enables access to the resource server. The mesh agent may be employed to communicate the client request and the credential information to the resource server; determining a response to the client request from the resource server; employing the mesh agent to receive a response to the client request from the resource server and forwarded to the client over the overlay network.

Abstract: An acoustic monitoring system characterizes, classifies, and geo-locates anthropogenic and natural sounds in near real time. The system includes a compact array of three acoustic vector sensors, which measures acoustic pressure and the three-dimensional particle velocity vector associated with the propagation of an acoustic wave, thereby inherently providing bearing information to an underwater source of sound. Beamforming techniques provide sound source localization, allowing for characterization of the acoustic signature of specific underwater acoustic sources.

Abstract: The invention is directed towards a method and system for optically-based monitoring of chemicals of potential concern (COPCs), including mercury (Hg), methyl mercury (MeHg), and polychlorinated biphenyls (PCBs). It employs a multi-parameter statistical analysis model, such as partial least square regression (PLS regression), to identify combinations of predictors (e.g., optical, water quality, and physical properties) that have large covariance with the response values. The predictive model is validated against analytic samples from laboratories. The steps in the method are repeated until predictors, or parameters are selected that avoid over-fitting and which yield physically-based results.
