Patent number: 11580109Abstract: Method and apparatus for stress management in a searchable data service. The searchable data service may provide a searchable index to a backend data store, and an interface to build and query the searchable index, that enables client applications to search for and retrieve locators for stored entities in the backend data store. Embodiments of the searchable data service may implement a distributed stress management mechanism that may provide functionality including, but not limited to, the automated monitoring of critical resources, analysis of resource usage, and decisions on and performance of actions to keep resource usage within comfort zones. In one embodiment, in response to usage of a particular resource being detected as out of the comfort zone on a node, an action may be performed to transfer at least part of the resource usage for the local resource to another node that provides a similar resource.Type: GrantFiled: May 22, 2020Date of Patent: February 14, 2023Assignee: Amazon Technologies, Inc.Inventors: Patrick W. Ransil, Aleksey Martynov, James Larson, James R. Collette, Robert Wai-Chi Chu, Partha Saha

Patent number: 9542926Abstract: The techniques disclosed herein allow a user to synchronize the playing and displaying of digital content on an electronic device. The device may render a first portion of digital content so it may be displayed. The device may also play a segment of the digital content as audio using text to speech software. The device may also render a second portion of digital content for display depending on whether the position of the last word read is greater than the last position in the first portion of digital content.Type: GrantFiled: March 12, 2014Date of Patent: January 10, 2017Assignee: Amazon Technologies, Inc.Inventors: Laurent An Minh Nguyen, Edward J. Gayles, Robert Wai-Chi Chu, Dennis Paul Fleming, Sailesh Rachabathuni, David Berbessou

Patent number: 8552992Abstract: A method is disclosed for specifying textual input for a computing device using a multi-directional input device. Each character of a textual group is associated with a different angle. Each character of the textual group is displayed on a display screen at the associated angle. A swipe angle of a directional swipe received at a multi-directional pointing device is determined. The associated angle closest to the swipe angle is identified. The character of the textual group corresponding to the identified angle on the display screen is highlighted.Type: GrantFiled: June 30, 2008Date of Patent: October 8, 2013Assignee: Amazon Technologies, Inc.Inventors: John T.

Patent number: 8554758Abstract: Method and apparatus for monitoring and maintaining group health and membership in a searchable data service. The searchable data service may provide a searchable index to a backend data store, and an interface to build and query the searchable index, that enables client applications to search for and retrieve locators for stored entities in the backend data store. Embodiments of the searchable data service may implement a group health mechanism that may allow one or more components of the searchable data service to identify sets of nodes that the components may monitor. A group health component may be queried by the other components for automatically-refreshed health information about those nodes. The group health component may perform as a node failure detection mechanism. Node health information may be communicated among nodes at least in part using a gossip protocol.Type: GrantFiled: March 29, 2006Date of Patent: October 8, 2013Assignee: Amazon Technologies, Inc.Inventors: James S.
