Patent number: 11617917Abstract: Aspects of the present disclosure provide methods, apparatuses, and systems for non-linear breathing entrainment. As described herein, “breathing entrainment” refers to guiding a user's breath or breathing. According to an aspect, an initial breathing period and a final breathing period are selected. Based on the initial and final breathing periods, a non-linear breath rate per minute sequence is determined. A guiding stimulus is output and aligned with the non-linear breath rate per minute sequence. The guiding stimulus is non-linearly altered with the non-linear breath rate per minute sequence to align with the final breathing period over an interval of time. The non-linear alterations of the guiding stimulus vary based on an amount of time the guiding stimulus has been output.Type: GrantFiled: January 6, 2020Date of Patent: April 4, 2023Assignee: BOSE CORPORATIONInventors: Harsh A. Mankodi, David Rolland Crist, Christopher R. Paetsch, Joseph Rossi, Sara Adkins, Chia-Ling Li, Navaneethan Siva, Kathleen Elizabeth Kremer, Alexander de Raadt St James, Jeffrey Miller, Connor Rog, Stephen A.

Publication number: 20220273909Abstract: Aspects of the present disclosure provide methods, apparatuses, and systems for non-linearly decreasing an auditory experience output. According to an aspect, a non-linear decreasing rate is applied to an audio output of the auditory experience. The non-linear decreasing rate varies as a function of decibel amplitude over time in seconds. The non-linear decreasing rate comprises a plurality of segments connected together. The audio of the guided breathing is output at the non-linear decreasing rate until a decibel level of the audio output is below one of a decibel level of ambient noises in a user's environment or a predetermined decibel level.Type: ApplicationFiled: August 5, 2020Publication date: September 1, 2022Applicant: BOSE CORPORATIONInventors: Harsh A.

Publication number: 20220080258Abstract: Aspects of the present disclosure provide methods, apparatuses, and systems for non-linear breathing entrainment. According to an aspect, a final breathing period is selected, and a current breathing period of a user is measured. A guiding stimulus configured to alter the current breathing period towards the final breathing period over an interval of time at a non-linear prescribed rate is output. A difference between the current breathing period and a target breathing period along the non-linear linear prescribed rate is determined. Based at least in part on the difference, the guiding stimulus and/or the non-linear prescribed rate are adjusted. The guiding stimulus and the non-linear prescribed rate may be stabilized, increased, or decreased to enable the user to reach the final breathing period.Type: ApplicationFiled: January 6, 2020Publication date: March 17, 2022Inventors: Harsh A.

Patent number: 11191448Abstract: Aspects of the present disclosure provide methods, apparatuses, and systems for dynamic starting rates for guided breathing. According to an aspect, a user's initial breathing metric is determined. A multiplier is then determined, where the multiplier varies as a function of the initial breathing metric within a range. The level of intensity of the multiplier may vary, and may be a dynamic feature based on the determination of the user's initial breathing metric. Once the multiplier is determined, the multiplier is applied to the user's initial breathing metric to determine a starting breathing metric for guided breathing. The starting breathing metric is slower than or equal to the user's initial breathing metric.Type: GrantFiled: June 7, 2019Date of Patent: December 7, 2021Assignee: BOSE CORPORATIONInventors: Harsh A. Mankodi, Chia-Chun Hsu, David Rolland Crist, Kathleen Elizabeth Kremer
