Patent number: 11990122Abstract: Techniques for recommending a skill experience to a user after a user-system dialog session has ended are described. Upon a dialog session ending, the system uses a first machine learning model to determine potential intents to recommend to a user. The system then uses a second machine learning model to determine a particular skill and intent to recommend. The system then prompts the user to accept the recommended skill and intent. If the user accepts, the system calls the recommended skill to execute. As part of calling the skill, the system sends to the skill at least one entity provided in a natural language user input of the ended dialog session. This enables the skill to skip welcome prompts, and initiate processing to output a response based on the intent and the at least one entity of the ended dialog session.Type: GrantFiled: December 7, 2022Date of Patent: May 21, 2024Assignee: Amazon Technologies, Inc.Inventors: Ruhi Sarikaya, Hung Tuan Pham, Savas Parastatidis, Dean Curtis, Pushpendre Rastogi, Nitin Ashok Jain, John Arland Nave, Abhinav Sethy, Arpit Gupta, Mayank Kumar, Nakul Dahiwade, Arshdeep Singh, Nikhil Reddy Kortha, Rohit Prasad

Patent number: 11990127Abstract: Systems, methods, and devices for recognizing a user are disclosed. A speech-controlled device captures a spoken utterance, and sends audio data corresponding thereto to a server. The server determines content sources storing or having access to content responsive to the spoken utterance. The server also determines multiple users associated with a profile of the speech-controlled device. Using the audio data, the server may determine user recognition data with respect to each user indicated in the speech-controlled device's profile. The server may also receive user recognition confidence threshold data from each of the content sources. The server may determine user recognition data associated that satisfies (i.e., meets or exceeds) a most stringent (i.e., highest) of the user recognition confidence threshold data. Thereafter, the server may send data indicating a user associated with the user recognition data to all of the content sources.Type: GrantFiled: September 16, 2022Date of Patent: May 21, 2024Assignee: Amazon Technologies, Inc.Inventors: Natalia Vladimirovna Mamkina, Naomi Bancroft, Nishant Kumar, Shamitha Somashekar

Publication number: 20240160531Abstract: Changes made to a database table are accumulated, in durable storage, and snapshots of partitions of the table are obtained. For successive snapshots of a partition, the system accesses a previous snapshot, applies changes from the accumulated changes, and stores the updated snapshot to a durable data store. The accumulated changes and the successive partition snapshots are made available to restore the database to any point in time across a continuum between successive snapshots. Although each partition of the table may have a backup snapshot that was generated at a time different from when other partition snapshots were generated, changes from respective change logs may be selectively log-applied to distinct partitions of a table to generate an on-demand backup of the entire table at common point-in-time across partitions. Point-in-time restores of a table may rely upon a similar process to coalesce partition snapshots that are not aligned in time.Type: ApplicationFiled: November 15, 2023Publication date: May 16, 2024Applicant: Amazon Technologies, Inc.Inventors: Akshat Vig, Tate Andrew Certain, Go Hori

Patent number: 11982563Abstract: An apparatus powered by batteries may include a first processor and a second processor. The first processor may consume more electrical power than the second processor. The second processor acquires data from one or more sensors. At a predetermined time or other trigger, the second processor activates the first processor that is then used to send the acquired data to an external device. For example, items are stowed on the apparatus that includes weight sensors. The second processor awakens hourly, acquires weight data indicative of the weight of items stowed on the apparatus, and returns to a sleep mode. After 24 hours of acquiring weight data, the second processor activates the first processor to send the accumulated weight data to an external device, such as a server, using a network interface. Power consumption is substantially reduced, allowing the apparatus to operate without external power for extended periods of times.Type: GrantFiled: September 28, 2020Date of Patent: May 14, 2024Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Andrew William Staats, Charles Robert Watson, David Buuck, Dave Jonathan Lefkow, Paul Ellis

Patent number: 11985055Abstract: Hop counts can be determined in a variety of network segments using packet headers collected at boundaries of the segments. Agents executing on network devices are used to transmit packet header data, including a TTL budget, to a collector server computer. The collector server computer can discern signal (production flows) from noise (traceroutes and probing traffic), detecting packets that are at risk of being dropped due to TTL expiration. Alerts can be generated for packet flows with a dangerously low remaining TTL budget, which are at high risk of expiring due to operational events resulting in traffic temporarily traversing slightly longer paths. Source addresses can be identified for such packet flows and network devices through which the packet flows are traversing can be identified. Hop counts can then be computed for different network segments, such as an Internet segment, a backbone segment and a data center segment.Type: GrantFiled: September 13, 2021Date of Patent: May 14, 2024Assignee: Amazon Technologies, Inc.Inventor: Sameh George Alphonse Saad

Patent number: 11985179Abstract: A system configured to improve a voice quality during a communication session by performing bandwidth extension on a narrowband speech signal to generate a wideband speech signal with higher audio quality. For example, a system can extend a speech bandwidth from a narrowband signal having a first bandwidth (e.g., 4 kHz) to a wideband signal having a second bandwidth (e.g., 8 kHz or higher). To perform bandwidth extension, the system may include cascaded neural networks, such as two or more sub-pixel convolutional neural networks (CNNs) connected in series. In some examples, a first sub-pixel CNN may extend the speech bandwidth from 4 kHz to 6 kHz and a second sub-pixel CNN may extend the speech bandwidth from 6 kHz to 8 kHz. Alternatively, the system may use three or more cascaded neural networks and/or may extend the speech bandwidth above 8 kHz without departing from the disclosure.Type: GrantFiled: November 23, 2020Date of Patent: May 14, 2024Assignee: Amazon Technologies, Inc.Inventors: Berkant Tacer, Nikhil Shankar
