Patent number: 11614529Abstract: Techniques for presence-detection devices to emission levels of ultrasonic signals that are used to detect movement in an environment. The presence-detection devices may detect movement of a person by emitting the ultrasonic signals into an environment, and characterizing the change in the frequency, or the Doppler shift, of the reflections of the ultrasonic signals off the person caused by the movement of the person relative to the presence-detection devices. However, presence-detection devices that continuously emit ultrasonic signals may experience reduced battery life, increased likelihood of overheating, etc. To reduce these negative effects, the presence-detection devices may reduce the emission levels of ultrasonic signals. For instance, once motion is detected, the presence-detection devices may, for a period of time, stop emitting ultrasonic signals or reduce the power level at which the ultrasonic signals are emitted.Type: GrantFiled: March 19, 2021Date of Patent: March 28, 2023Assignee: Amazon Technologies, Inc.Inventors: Harsha Inna Kedage Rao, Maziyar Khorasani, Tarun Pruthi, Krishna Kamath Koteshwara

Publication number: 20220215837Abstract: This disclosure describes, in part, context-based device arbitration techniques to select a voice-enabled device from multiple voice-enabled devices to provide a response to a command included in a speech utterance of a user. In some examples, the context-driven arbitration techniques may include determining a ranked list of voice-enabled devices that are ranked based on audio signal metric values for audio signals generated by each voice-enabled device, and iteratively moving through the list to determine, based on device states of the voice-enabled devices, whether one of the voice-enabled devices can perform an action responsive to the command. If the voice-enabled devices that detected the speech utterance are unable to perform the action responsive to the command, all other voice-enabled devices associated with an account may be analyzed to determine whether one of the other voice-enabled devices can perform the action responsive to the command in the speech utterance.Type: ApplicationFiled: March 22, 2022Publication date: July 7, 2022Inventors: Joseph White, Ravi Kiran Rachakonda, Vinodth Kumar Mohanam, Lalithkumar Rajendran, Deepak Uttam Shah, Maziyar Khorasani, Venkata Snehith Cherukuri

Patent number: 10565956Abstract: A method and apparatus filter light spectrum. Ambient light conditions of light that is ambient to a user device can be sensed. Ambient light color conditions can be determined based on the sensed ambient light conditions. User device charging times when the user device is being charged can be monitored. User device motion including movement of the user device can be monitored. User device activity can be monitored. Color-modified image display times can be ascertained from at least one selected from the user device motion, the user device activity, and the user device charging times. A color-modified image can be generated based on at least the ambient light color conditions and the color-modified image display times. The color-modified image can be displayed.Type: GrantFiled: November 23, 2016Date of Patent: February 18, 2020Assignee: Motorola Mobility LLCInventors: Maziyar Khorasani, Kevin McDunn, Seang Chau, Kevin Foy, Lauren Schwendimann, Xiaodong Xun, Joseph Swantek, Mir Farooq Ali, Jun Ki Min
