Fall Detection
Patently Apple first covered Apple's first 'Fall Detection" patent back in 2018. Today, Apple was granted a second patent related to Fall Detection officially titled "Detecting Falls using a Mobile Device." Apple notes on their support page that "If Apple Watch Series 4 detects a hard fall while you're wearing your watch, it taps you on the wrist, sounds an alarm, and displays an alert. You can choose to contact emergency services or dismiss the alert by pressing the Digital Crown, tapping Close in the upper-left corner, or tapping 'I'm OK.'"
Apple's patent FIG. 1 below illustrates an example system #100 for determining whether a user has fallen and is in need of assistance. The system includes an Apple Watch (#102), a server computer system (#104) that communicates with a variety of devices (#106) and a network (#108); FIG. 9 is a diagram of an example decision tree for determining that either a user has fallen and may be in need of assistance, or a user has either not fallen or has fallen but is not in need of assistance.
Apple's patent FIG. 2A above is a diagram showing an example position of a mobile device on a user's body; FIG. 2B is a diagram showing example directional axes with respect a mobile device.
For those wanting to take a deep dive into the invention's details, see Apple's granted patent US 11527140 B2. In this second granted patent, Apple added an additional 32 new patent claims to better protect their invention. Patent Claims can be found at the very bottom of the granted patent
