Patent number: 11521599Abstract: A system and method performs wakeword detection using a feedforward neural network model. A first output of the model indicates when the wakeword appears on a right side of a first window of input audio data. A second output of the model indicates when the wakeword appears in the center of a second window of input audio data. A third output of the model indicates when the wakeword appears on a left side of a third window of input audio data. Using these outputs, the system and method determine a beginpoint and endpoint of the wakeword.Type: GrantFiled: September 20, 2019Date of Patent: December 6, 2022Assignee: Amazon Technologies, Inc.Inventors: Christin Jose, Yuriy Mishchenko, Anish N. Shah, Alex Escott, Parind Shah, Shiv Naga Prasad Vitaladevuni, Thibaud Senechal

Publication number: 20210327442Abstract: A system may embed audio watermarks in audio data using an Eigenvector matrix. The system may detect audio watermarks in audio data despite the effects of reverberation. For example, the system may embed multiple repetitions of an audio watermark before generating output audio using loudspeaker(s). To detect the audio watermark in audio data generated by a microphone, the system may perform a self-correlation that indicates where the audio watermark is repeated. In some examples, the system may encode the audio watermark using multiple repetitions of a multi-segment Eigenvector. Additionally or alternatively, the system may encode the audio watermark using a binary sequence of positive and negative values, which may be used as a shared key for encoding/decoding the audio watermark. The audio watermark can be embedded in output audio data to enable wakeword suppression (e.g., avoid cross-talk between devices) and/or local signal transmission between devices in proximity to each other.Type: ApplicationFiled: March 15, 2021Publication date: October 21, 2021Inventors: Yuan-Yen Tai, Mohamed Mansour, Parind Shah

Patent number: 9952809Abstract: A data handling system having a physical storage device and a storage controller responsible for provisioning, managing, and servicing logical unit numbers (LUNs) with self-destruction properties on the physical storage device is disclosed. For a given LUN, the storage controller creates a profile including self-destruction properties, such as a LUN destruction date, and associates the profile with the LUN. The profiles may be independent of file format and content of any associated data and the LUN destruction date may be a function of the last access date of the associated data. The storage controller monitors the LUN destruction date associated with each LUN and determines the last access date of any associated data. The storage controller marks a LUN having a past-due LUN destruction date, notifies a user of an approaching LUN destruction date, and destroys any past-due LUNs.Type: GrantFiled: November 1, 2013Date of Patent: April 24, 2018Assignee: DELL PRODUCTS, L.P.Inventor: Parind Shah

Patent number: 7660880Abstract: User access to applications is controlled by associating an alias for an individual with a user profile for the individual; the user profile typically contains data referring to one or more applications. Access to an application is obtained using the data in the user profile, e.g., through automatic completion of forms or screens within an application. In addition, the user profile may be employed to limit user access to parts of an application, or to terminate a user's access to an application.Type: GrantFiled: March 21, 2003Date of Patent: February 9, 2010Assignee: Imprivata, Inc.Inventors: David M. T. Ting, Chen Ho, Parind Shah, Bushan Yadav Byragani
