The analyzing unit analyzes an acoustic-signal and extracts a feature-quantity. The clipping unit clips, from the voice-recognition-result, the feature-quantity sequence included in an utterance section.

Abstract: A storage device may use unused bits in a memory device communicatively coupled to the storage device to reduce resource usage and time on the storage device during background operations. The memory device includes a plane having a redundant column section including unused bits. When the storage device receives instructions from a host device, a controller on the storage device may determine that the instructions are associated with data to be discarded from the memory device and may associate the data to be discarded with fragments in the memory device. The controller may generate relocation information, associate the relocation information with data stored in the memory device, and store the relocation information in the unused bits. During relocation operations, the controller may use the relocation information to determine whether fragments in the memory device include the data to be discarded and/or whether to move data in the memory device.

Abstract: A multi-protocol storage device avoids entering a thermal shutdown mode by switching between protocols. The storage device communicates with a host in a first mode using a first protocol. The storage device receives a temperature request from the host, monitors its temperature, and transmits a response to the host when the temperature of the storage device meets a predefined temperature that is below a thermal shutdown threshold. The storage device receives a thermal throttling instruction from the host and switches to a second mode to communicate with the host using a second protocol that uses less resources than the first protocol. The storage device performs thermal throttling until the temperature of the storage device reaches a normal temperature zone. When the temperature of the storage device returns to the normal temperature zone, the storage device returns to the first mode.

Abstract: To achieve no code or low code parity in decentralized computing systems, disclosed implementations provide a data structure and trusted control plane that enables the creation and operation of composable objects, that is objects whose functions and properties are derived from configurable and upgradable templates. The templates are data structures that define the behavior of a collection of objects, the behaviors being the interfaces, functions, properties, events, triggers, error messages, and dependencies that define and object and its interaction with other objects and entities. Templates are configured by mapping the desired object behaviors to registered smart contract logic that affects the behaviors. Thus, complex objects can be composed without the need for new computer code. Additional logic to enable new behaviors can be added by authorized smart contract developers and, once certified, added to one or more templates to provide the objects access to the new capabilities.
