Abstract: Examples described herein relate to management of concurrent audio streams from different sources. Portable playback devices, such as wearable wireless headphones and earbuds, as well as portable battery-powered speakers, may include multiple network interfaces for connection to different types of networks, such as an 802.11-compatible network interface for connection to wireless local area networks (e.g., Wi-Fi® networks) and an 802.15-compatible network interface for connection to a mobile device via a personal area network (Bluetooth®). Via such connections, the playback devices may receive two or more concurrent streams. By managing these streams according to playback policies, the portable playback devices may play the user's intended audio without necessarily requiring user input to explicitly select among the concurrent streams.

Abstract: An example implementation includes a device that includes a base infrastructure inspection unit and a plurality of modular sensor units attached to the base infrastructure inspection unit. The base infrastructure inspection unit includes a set of one or more processors and a memory device having code executable by the one or more processors. The executable code synchronizes the plurality of sensor units, captures two or more data streams of infrastructure inspection data, combines the data with metadata indicating synchronization between respective ones of the plurality of sensor units, and provides combined metadata and infrastructure inspection data for inclusion in a photorealistic image based on a three-dimensional (3D) model of the infrastructure.

Abstract: Methods, systems, and computer program products for direct assignment of physical devices to confidential virtual machines (VMs). At a first guest privilege context of a guest partition, a direct assignment of a physical device associated with a host computer system to the guest partition is identified. The guest partition includes the first guest privilege context and a second guest privilege context, which is restricted from accessing memory associated with the first guest privilege context. The guest partition corresponds to a confidential VM, such that a memory region associated with the guest partition is inaccessible to a host operating system. It is determined, based on a policy, that the physical device is allowed to be directly assigned to the guest partition. Communication between the physical device and the second guest privilege context is permitted, such as by exposing the physical device on a virtual bus and/or forwarding an interrupt.

Abstract: The application is directed to methods and devices for estimating corrosion of a material. One of the methods includes obtaining data regarding corrosion. The data is obtained from various sources, such as but not limited to sensors and observational data. The data is then trained to provide for a more complete data set. The trained data is then used to estimate the expected amount of corrosion for a given situation.

Abstract: A program is executed using a call stack and shadow stack. The call stack includes frames having respective return addresses. The frames may also store variables and/or parameters. The shadow stack stores duplicates of the return addresses in the call stack. The call stack and the shadow stack are maintained by, (i) each time a function is called, adding a corresponding stack frame to the call stack and adding a corresponding return address to the shadow stack, and (ii) each time a function is exited, removing a corresponding frame from the call stack and removing a corresponding return address from the shadow stack. A backtrace of the program's current call chain is generated by accessing the return addresses in the shadow stack. The outputted backtrace includes the return addresses from the shadow stack and/or information about the traced functions that is derived from the shadow stack's return addresses.

Abstract: Systems and methods enable most valuable players (MVPs) of a gameplay session to play a bonus gameplay session where other players (non-MVP players) participate as player-spectators in online video games and, through a collective voting mechanism or through active interaction, determine the occurrence of certain events or contents of the bonus gameplay in real time. In this manner, non-MVP players are able to directly affect the course of the bonus gameplay.

Abstract: Performing shadow stack functionality for a thread in an audit mode includes initiating execution of a thread at the processor. Execution of the thread includes initiating execution of executable code of an application binary as part of the thread and enabling shadow stack functionality for the thread in an audit mode. Based at least on the execution of the thread in the audit mode, at least a portion of the shadow stack is enabled to be a circular stack. In response to determining that usage of the shadow stack has reached the defined threshold, one or more currently used entries of the shadow stack are overwritten, preventing the shadow stack from overflowing.

Abstract: This application discloses a wind pressure-driven air intake device for natural ventilation of zero power consumption. Such a device comprises multiple tunnels being arranged around a common central chamber, each having an inflow valve at its inner end connecting the central chamber and an outer end open to ambient airflow. The inflow valve allows only inward flow from a corresponding tunnel into the central chamber. The central chamber has an opening allowing airflow exit to a space to be ventilated. The device is capable of capturing ambient wind flow and wind pressure to be fed to the vented space regardless of wind flow direction towards the device, with no need for a powered air driver.

Abstract: A natural ventilator is herein disclosed that is free of moving parts, wind-activated, rain-proof, and free of dust or smog infiltration. It is not only suitable to be a standalone natural ventilator, but is also advantageous to be used as an enhanced exhaust exit in a forced-air ventilation system, for such enclosed spaces or objects as buildings and vehicles needing air relief. The ventilator assembly has rainwater-proof shapes or fixtures that serve to defend the vent system, and the interior space being vented, against rainwater invasion, even if raindrop trajectory becomes highly oblique from vertical as driven by strong winds. It also includes shapes or fixtures to prevent fume condensation from drifting outward and staining the exterior of a building or vehicle, or the like, that is being vented.

Abstract: Enforcing shadow stack violations at module granularity, rather than at thread or process granularity. An exception is processed during execution of a thread based on code of an application binary, which is enabled for shadow stack enforcement, that calls an external module. The exception results from a mismatch between a return address popped from the thread's call stack and a return address popped from the thread's shadow stack. Processing the exception includes determining that the exception resulted from execution of an instruction in the external module, and determining whether or not the external module is enabled for shadow stack enforcement. Based at least on these determinations, execution of the thread is terminated when the external module is enabled for shadow stack enforcement, or the thread is permitted to continue executing when the external module is not enabled for shadow stack enforcement.
