  • Patent number: 12356163
    Abstract: A wearable audio output device (e.g., headphones) having an open design that allows ambient noise to pass to a listener without physically isolating the listener from a surrounding environment. The device may include an open earcup design that may partially or completely surround the listener's ear, and in some examples a portion of the listener's head may be uncovered by the open earcup. To improve comfort, the device includes a floating audio component configured to generate output audio in a direction of the listener's ear without contacting the listener's ear. To reduce audio leakage into the environment, the floating audio component may include two audio transducers and perform beamforming to target the output audio toward the listener's ear and cancel the output audio in other directions. For example, the beamforming may cause constructive interference in one direction and destructive interference in all other directions.

  • Patent number: 12355873
    Abstract: Techniques for secure cryptographic secret bootstrapping balance the need to quickly and conveniently restore cryptographic secrets to server computers in the event of an outage with the need for security. Before the outage, a server computer uses a trusted platform module of the server computer to seal an encryption key used to encrypt a secret stored at the server computer. In response to the outage, the server computer restores the secret by using the trusted platform module to unseal the encryption key and then using the unsealed encryption key to decrypt the encrypted secret. The techniques can be used to restore cryptographic secrets rapidly and securely to a cluster of server computers used for cryptographic operations in a provider network without the overhead of safe room procedures.

  • Publication number: 20250217046
    Abstract: Techniques are described for managing access of executing programs to non-local block data storage. In some situations, a block data storage service uses multiple server storage systems to reliably store network-accessible block data storage volumes that may be used by programs executing on other physical computing systems. A group of multiple server block data storage systems that store block data volumes may in some situations be co-located at a data center, and programs that use volumes stored there may execute on other physical computing systems at that data center. If a program using a volume becomes unavailable, another program (e.g., another copy of the same program) may in some situations obtain access to and continue to use the same volume, such as in an automatic manner in some such situations.

  • Publication number: 20250217057
    Abstract: An operating system, or operating system update, management service uses a shared read-only multi-attach volume of a block-based storage service to distribute operating systems or operating system updates to a set of virtualized computing instances. Also, to store launch specific information, that is specific to a given virtualized computing instance, additional writable volumes are used, wherein a write volume is attached to each of the computing instances of the set. This eliminates the need to provide a full copy of an OS volume to each of the computing instances.

  • Patent number: 12348529
    Abstract: Techniques are described for providing a policy refiner application used to analyze and recommend modifications to identity and access management policies created by users of a cloud provider network (e.g., to move the policies toward least-privilege permissions). A policy refiner application receives as input a policy to analyze, and a log of events related to activity associated with one or more accounts of a cloud provider network. The policy refiner application can identify, from the log of events, actions that were permitted based on particular statements contained in the policy. Based on field values contained in the corresponding events, the policy refiner application generates an abstraction of the field values, where the abstraction of the field values may represent a more restrictive version of the field from a policy perspective. These abstractions can be presented to users as recommendations for modifying their policy to reduce the privileges granted by the policy.

  • Patent number: 12343631
    Abstract: Network simulation systems and methods to execute and manage simulations or games are disclosed. The simulations or games are managed so that participants of each team are prevented from having access to information which they are not expected or supposed to have in the context of a fair simulation or game. To do this, a server, in addition to running a complete simulation, runs partial simulations for each particular team based only on information available to each particular team, where the partial simulations match the simulations done locally by clients. The server also generates and transmits correction patches to the clients, and the clients use the correction patches to modify their partial simulations to incorporate information from the complete simulation which is allowed to be accessed by the client.

  • Patent number: 12347488
    Abstract: A Content-Addressable Memory (CAM) is disclosed in which a single lookup request is split into several iterations, with each iteration having a partial lookup. Results of the partial lookups are incrementally accumulated to obtain a final lookup result. The incremental CAM lookup allows for smaller CAM hardware to be used than typically needed for a similar size lookup, which saves area and power over prior approaches. In one embodiment, a memory is used in conjunction with a CAM and the CAM is configured on each partial lookup using a read from the memory. Accumulation logic can then be used to logically combine the results of the partial lookups.
