摘要： A computing system that is configured to receive requests to send computer executable programs to a data owner system associated with a data source for execution of the computer executable program by the data owner system. The data owner system may store to a blockchain a permitted list of programming functions, function libraries, function syntax definitions, and execution environment requirements. The computing system may be further configured to retrieve the permitted lists. The computing system may be further configured to evaluate the computer executable program using the permitted lists to determine if the computer executable program may be executed by the data owner system. The evaluation may be performed by generating an abstract syntax tree of the computer executable program. The computing system may be further configured to send the computer executable program to the data owner system if the computer executable program satisfies the conditions of the permitted lists.

摘要： A first component determines encrypted data representing an event and encrypted threshold data corresponding to an outlier of the event. The first system may process the data using, for example, one or more composite integers, and may send the result to a second system. This second system may subtract the data to determine of the encrypted data is greater than, less than, or equal to the encrypted threshold. If so, the second system may determine that the encrypted data corresponds to an outlier of the data. The second system may send an indication of this determination to a third system.

摘要： Described herein is a system for emotion detection in audio data using a speaker's baseline. The baseline may represent a user's speaking style in a neutral emotional state. The system is configured to compare the user's baseline with input audio representing speech from the user to determine an emotion of the user. The system may store multiple baselines for the user, each associated with a different context (e.g., environment, activity, etc.), and select one of the baselines to compare with the input audio based on the contextual situation.

摘要： A system and method includes a first device (e.g., a primary wireless in-ear device) connected to a second device (e.g., a secondary wireless in-ear device) using a first wireless connection. The first device is also connected to a third device (e.g., a smartphone or smart watch) using a second wireless connection. The first device and second device determine signal quality metrics corresponding to the quality of the wireless signal received by each from the third device. If the second device reports having a better signal quality, communication with the third device is handed off from the first device to the second device.

摘要： A snow thrower is disclosed having a reverse shut-off mechanism configured to deactivate voltage supplied from a power source to a motor that rotates an auger assembly. The reverse shut-off mechanism deactivates the voltage supplied in response to the snow thrower being moved or rolled in a reverse direction. Upon movement of the snow thrower in a forwards direction to clear snow or other debris, the shut-off mechanism reactivates voltage supplied from the power source to the motor that rotates the auger assembly. This allows the snow thrower to conserve power and/or fuel when the snow thrower is not being used to clear snow or other debris.

摘要： A first system receives an encrypted data vector representing a text search query from a second system and second encrypted data from a third system that may include a first vector and a second vector representing text of an electronic document. The first system may multiply the vectors by a random vector. The first system may determine a first difference between the encrypted data vector and the first vector, and a second difference between the encrypted data vector and the second vector. The first system may determine a product of the first and second difference. The first system may send the product to the third system and then receive a value representing the decrypted difference. The first system may determine if the value satisfies a condition and send the result of the determination to the second system.

摘要： A system and method to manage handover between wireless audio devices (such as earbuds) of primary responsibility for communicating with a third device such as a phone or tablet. A first wireless audio output device manages communications between a third device and a second wireless audio output device. The wireless audio output devices determine the signal quality of the connection between them. If that signal quality drops below a threshold, the wireless audio output devices determine the rate of change of that signal quality. If that quality is dropping rapidly, the wireless audio output devices check to see which has the better connection to the third device. If the second wireless audio output device has a better connection to the third device than that of the first wireless audio output device, then the wireless audio output devices can trigger a handover from the first wireless audio output device to the second wireless audio output device.

摘要： A system configured to perform low power mode wakeword detection is provided. A device reduces power consumption without compromising functionality by placing a primary processor into a low power mode and using a secondary processor to monitor for sound detection. The secondary processor stores input audio data in a buffer component while performing sound detection on the input audio data. If the secondary processor detects a sound, the secondary processor sends an interrupt signal to the primary processor, causing the primary processor to enter an active mode. While in the active mode, the primary processor performs wakeword detection using the buffered audio data. To reduce a latency, the primary processor processes the buffered audio data at an accelerated rate. In some examples, the device may further reduce power consumption by including a second buffer component and only processing the input audio data after detecting a sound.

摘要： A speech-processing system receives both text data and natural-understanding data (e.g., a domain, intent, and/or entity) related to a command represented in the text data. The system uses the natural-understanding data to vary vocal characteristics in determining spectrogram data corresponding to the text data based on the natural-understanding data.
