[0028] DETAILED DESCRIPTION OF THE INVENTION The specific design, application and details are described to enable any person skilled in the art to make and use the invention. It is obvious that those skilled in the art can make various modifications to the present invention according to the general principle in the present invention without departing from the spirit and scope of the present invention. Accordingly, the present invention is not intended to be limited to the illustrated implementation examples, but is to be accorded the widest coverage consistent with the principles, features and techniques disclosed herein.

[0029] figure 1 (A) and (B) show the principle of detecting whether a fall has occurred based on direct monitoring of changes in the relative position and orientation between the host and the local gravity direction when the fall event occurs. The host can be any object that we need to watch if it falls, such as a person, robot, or vehicle. The orientatio...

Abstract

The invention designs a unique suspended multi-purpose magnetic sensor based on magnetic levitation. The sensor can be used in multiple aspects such as fall detection, tilt measurement and vibration measurement. Meanwhile, a mass manufacturing process of the multi-purpose magnetic sensor is illustrated, and a detection method for specific application of the multi-purpose magnetic sensor in fall detection is disclosed.

Description

technical field [0001] The present invention relates to MEMS sensors that can be used for fall detection, digital tilt angle measurement relative to gravity direction, high-sensitivity digital mechanical vibration and mechanical pulse measurement, etc., and mass production of the sensor. Background technique [0002] Fall detection is very important, and it is widely used in elderly care, patient care, child care, disabled care, and outdoor sports such as skiing, hiking, cycling and other safety assurance. Producing a reliable fall detection system product has huge market potential and beneficial social impact. The conventional fall detection system based on the acceleration sensor uses a large number of different algorithms to establish the acceleration model or threshold of the fall event, and detects whether the fall event occurs by comparing the acceleration data obtained during the fall with the preset model or threshold. However, random fall events depend on the actua...
