Vorrichtung und Verfahren zur Sturzerkennung

DE 102009019767 A1 UPAB: 20101112 NOVELTY - The device has a three-dimensional acceleration sensor designed to measure acceleration vectors with three acceleration components of different spatial directions (X, Y, Z) at different time (t, t-1). An evaluating unit is designed to determine a dimension (teta) of orientation changes of the acceleration vectors of succeeding time points, from the acceleration components of different time points. A magnitude of the dimension for the orientation changes is compared with a limitation value for detecting fall of a person. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a mobile telephone that is provided with a unit for position determination (2) a method for detecting fall of the person in a mobile telephone. USE - Detecting device for use in a mobile telephone (claimed) for detecting fall of a person and for sending an emergency call, during falling. Can also be used for detecting tilting or slippage of a container, during position maintenance. ADVANTAGE - The design of the device ensures reliable detection of fall of a person at the earliest possible time and avoids the need for knowledge of direction of gravitational acceleration. The device is designed in an economical manner
