Publication number: 20240127683Abstract: In an example method, a mobile device obtains a signal indicating an acceleration measured by a sensor over a time period. The mobile device determines an impact experienced by the user based on the signal. The mobile device also determines, based on the signal, one or more first motion characteristics of the user during a time prior to the impact, and one or more second motion characteristics of the user during a time after the impact. The mobile device determines that the user has fallen based on the impact, the one or more first motion characteristics of the user, and the one or more second motion characteristics of the user, and in response, generates a notification indicating that the user has fallen.Type: ApplicationFiled: December 11, 2023Publication date: April 18, 2024Inventors: Xing Tan, Huayu Ding, Parisa Dehleh Hossein Zadeh, Harshavardhan Mylapilli, Hung A.

Publication number: 20240096199Abstract: Techniques are disclosed for facilitating disabling an alarm in response to particular types of activity-indicative data. More specifically, activity-indicative data (e.g., measurements obtained by an electronic device) can be detected prior to a preset alarm time. Upon determining, based on the activity-indicative data, that a wakefulness condition is satisfied, the alarm can be disabled such that the alarm stimuli is not to be presented at the preset alarm time.Type: ApplicationFiled: November 21, 2023Publication date: March 21, 2024Applicant: Apple Inc.Inventors: Bharath Narasimha Rao, Kevin Will Chen, Reed E.

Publication number: 20240033573Abstract: An electronic device may use motion and/or activity sensors to estimate a user's maximum volumetric flow of oxygen (VO2 max). In particular, the electronic device may use the user's heart rate, speed, and grade to determine the VO2 max. However, in indoor environments, it may be difficult to accurately measure the user's speed and grade. Therefore, the device may receive the speed and grade from external equipment, such as exercise equipment. To ensure that the user is moving at the reported speed, a discordance detector may compare the user's cadence to an expected cadence based on the speed and grade reported by the external equipment. If the user's cadence is within an acceptable range of the expected cadence, the user's VO2 max may be estimated based on the speed and grade. If the user's cadence is not within the acceptable range, the speed and grade may be discarded or corrected.Type: ApplicationFiled: April 10, 2023Publication date: February 1, 2024Inventors: Aditya Sarathy, Bharath Narasimha Rao, Umamahesh Srinivas

Publication number: 20210393162Abstract: One or more electronic device may use motion and/or activity sensors to estimate a user's maximum volumetric flow of oxygen, or VO2 max. In particular, although a correlation between heart rate and VO2 max may be linear at high heart rate levels, there is not a linear correlation at lower heart rate levels. Therefore, for users without extensive workout data, the motion sensors and activity sensors may be used to determine maximum calories burned by the user, workout data, including heart rate data, and body metric data. Based on these parameters, a personalized relationship between the user's heart rate and oxygen pulse (which is a function of VO2) may be determined, even with a lack of high intensity workout data. In this way, a maximum heart rate and therefore a VO2 max value may be approximated for the user.Type: ApplicationFiled: June 3, 2021Publication date: December 23, 2021Inventors: Britni A.
