Abstract: In some aspects, the disclosure is directed to methods and systems for a dynamic, reconfigurable virtual reality environment with in-environment access to external data and resources. Implementations of these systems also provide an external mechanism for modifying other aspects of the virtual reality experience with no need to recode or compile the experience. This can alter the primary flow of the experience, change its behavior based on the specific user accessing it and add branded or customer-specific aspects to the application. The same level or environment can provide drastically different experiences for various users from beginners through experts, even allowing the option of random or ordered events, controllable by an instructor or administrator, through simple configuration.

Abstract: Systems and methods are disclosed for efficient execution of code corresponding to smart contracts on a blockchain by utilization of trusted cloud primitives. As opposed to inefficient mechanisms that require individual nodes participating in a blockchain to independently execute smart contracts, embodiments of the present disclosure utilize a trusted consensus node, implemented by trusted code execution on a trusted cloud service provider, to execute smart contract code. Results of the execution can then be provided to participants for inclusion in the blockchain. The results are illustratively signed by the trusted cloud service provider, such that participants trust that the code executed properly without need for participants to trust one another with respect to the smart contract execution.

Abstract: Systems and methods are disclosed for efficient creation of blocks on a blockchain by utilization of trusted cloud primitives. As opposed to inefficient mechanisms like proof-of-work or application-limited mechanisms like proof-of-stake, embodiments of the present disclosure implement a consensus algorithm by execution of verifiably immutable code on one or more hosted computing environments that are mutually trusted by participants to the blockchain. The code can be designated within a block of the blockchain, such that participants mutually trust the code, when executed, to properly implement the agreed-upon consensus algorithm. The consensus algorithm can operate to select transactions for inclusion in each block, and notify participants of the selection, removing a need for participants to trust one another with respect to block creation.

Abstract: Countertop storage assembly are provided. In one example, a countertop storage assembly includes a countertop having a countertop area outer surface, a countertop area inner surface, and an opening formed therethrough. A retractable storage assembly includes a lid that is disposed in the opening when in a closed position and that moves between the closed position and an open, retracted position. During movement from the closed position to the open, retracted position, the lid moves downward and away from the opening to below the countertop off-set from the opening. A storage area includes a base that is in a retracted position situated below the countertop when the lid is in the closed position. The base moves from the retracted position to a deployed position where the base is disposed in the opening when the lid is in the open, retracted position.

Abstract: A service manages a plurality of virtual machine instances for low latency execution of user codes. The plurality of virtual machine instances can be configured based on a predetermined set of configurations. One or more containers may be created within the virtual machine instances. In response to a request to execute user code, the service identifies a pre-configured virtual machine instance suitable for executing the user code. The service can allocate the identified virtual machine instance to the user, create a new container within an instance already allocated to the user, or re-use a container already created for execution of the user code. When the user code has not been activated for a time-out period, the service can invalidate allocation of the virtual machine instance destroy the container. The time from receiving the request to beginning code execution is less than a predetermined duration, for example, 100 ms.

Abstract: Cabinets, methods for making cabinets, and aircraft including cabinets are provided. In one example, a cabinet includes a cabinet body that at least partially surrounds a cabinet space and that defines a cabinet opening that allows access to the cabinet space. A cabinet door at least partially covers the cabinet opening when in a closed position and extends upward from a lower edge portion to an upper edge portion. The cabinet door has an outer exposed surface facing generally in a first direction away from the cabinet space when in the closed position. The cabinet door is operatively coupled to the cabinet body for opening from the closed position to an open position including the lower edge portion moving generally upward and the upper edge portion moving generally upward and towards the first direction to expose the cabinet opening.

Abstract: A service manages a plurality of virtual machine instances for low latency execution of user codes. The service can provide the capability to execute user code in response to events triggered on an auxillary service to provide implicit and automatic rate matching and scaling between events being triggered on the auxiliary service and the corresponding execution of user code on various virtual machine instances. An auxiliary service may be configured as an event triggering service to detect events and generate event messages for execution of the user codes. The service can request, receive, or poll for event messages directly from the auxiliary service or via an intermediary message service. Event messages can be rapidly converted to requests to execute user code on the service. The time from processing the event message to initiating a request to begin code execution is less than a predetermined duration, for example, 100 ms.

Abstract: A microelectronic device that is radiation hardened through the incorporation of a quantum structure getter (QSG) is provided. The device, such as a field effect transistor (FET) includes a conductive channel and a material stack comprising: a capping layer, one or more barrier layers comprising a high band gap, one or more quantum structures comprising a small band gap, and a substrate. The quantum structures are positioned in close proximity to the conductive channel to form a quantum well charge getter. The getter forms a low energy area beneath the FET, which traps and confines electron-hole pair wave functions produced from ionizing radiation, causing the wave functions overlap, recombine, and produce light emission. The quantum structures getter the wave functions, which reduces the ionized photocurrent that reaches the conducting channel, thereby hardening the microelectronic device against ionizing radiation.
