APPARATUS AND METHOD FOR DETECTING DEVICE DROP - A simplified explanation of the abstract
This abstract first appeared for US patent application 18202796 titled 'APPARATUS AND METHOD FOR DETECTING DEVICE DROP
The patent application describes a method for detecting a drop event of an electronic device using sensor data from an inertial measurement unit (IMU).
- Obtaining angular velocity and proper acceleration of the electronic device from the IMU sensor.
- Calculating centripetal acceleration based on the angular velocity, principal moments of inertia, and position of the IMU sensor.
- Determining if the electronic device is in a fall state by comparing centripetal acceleration with proper acceleration.
- Providing an analysis result of the drop event if the electronic device is determined to be in a fall state.
Potential Applications: - Electronic devices with fall detection capabilities for improved safety features. - Wearable technology for monitoring user activity and detecting falls in real-time.
Problems Solved: - Enhancing the safety of electronic devices by detecting drop events. - Providing timely alerts or notifications in case of a fall.
Benefits: - Improved user safety and peace of mind. - Potential for reducing injuries or damage to electronic devices.
Commercial Applications: Title: "Smart Devices with Fall Detection Technology: Enhancing Safety Features in Wearable Tech" Description: This technology can be utilized in smartwatches, fitness trackers, and other wearable devices to provide users with advanced fall detection capabilities, making them ideal for elderly individuals, athletes, and anyone concerned about their safety during physical activities.
Questions about Fall Detection Technology: 1. How does this technology differentiate between a drop event and normal movement? 2. What are the potential limitations of using an IMU sensor for fall detection in electronic devices?
Original Abstract Submitted
A method for detecting a drop event of an electronic device, may include: obtaining an angular velocity and a proper acceleration of the electronic device based on sensor data received from an inertial measurement unit (IMU) sensor of the electronic device; obtaining centripetal acceleration of the electronic device based on the angular velocity, principal moments of inertia of the electronic device, and position of the IMU sensor within the electronic device; based on an acceleration difference between the centripetal acceleration and the proper acceleration, determining whether the electronic device is in a fall state; and based on the electronic device being determined to be in the fall state, providing an analysis result of the drop event.
