Embodiment Construction

[0111] figure 1 A mechanical implementation of the device for determining motion with static and dynamic acceleration components is shown on a base plate 7 inclined by an angle (α) relative to the horizontal 11 and having four sensors 1 - 4 .

[0112] Sensors 1-4 of the sensor set can be used to determine the following acceleration quantities:

[0113] - the angle (α) represents the inclination of the sensor unit, or more specifically the inclination of the base 7 with respect to the level 11,

[0114] - a parallel acceleration (PB), also called longitudinal acceleration, relative to the base 7, and

[0115] - Vertical acceleration (VB) relative to the base plate 7 .

[0116] Each of the four sensors 1-4 has a mass element 5 or 6, and each mass element is arranged on the base plate 7 through respective elastic supports 8, 9 and can pass through a plane perpendicular to the base plate 7 (ie the sensor plane) and deflected by the acceleration force. Every two supports are id...

Abstract

A device for measuring acceleration includes a base plate and mass elements connected to the base plate via elastic support elements having measuring points. The support elements of a first and a second mass element are constructed such that the support element of the first and the second mass element have at the measuring points an identical response characteristic for a first acceleration component in a first direction, and mutually different response characteristics for a second acceleration component perpendicular to the first component. The deflection of the measurement points is measured and evaluated. The component in the first and second directions is stepwise eliminated, and the result adjusted for the eliminated component is used for recovering these two components. The result adjusted for the eliminated component is measured as static acceleration and the component acting in the first and the second direction is measured as dynamic acceleration.

Description

technical field [0001] The present invention relates to a device and a method for detecting at least one acceleration, and to a corresponding computer program and a corresponding computer readable storage medium. The invention also relates to the use of a device suitable for separating static and dynamic accelerations, and to a corresponding computer program and a corresponding computer-readable storage medium, wherein said use comprises in particular analyzing and / or controlling motion. Background technique [0002] Dynamic recorders are used more and more, whether as speed odometers, for navigation, for controlling machines, during sports activities to detect motion, or even for controlling computer games. [0003] However, the prior art cannot solve the situation that most of the movements to be detected are particularly dynamic, because existing acceleration sensors are not able to separate the so-called static acceleration from the dynamic acceleration. [0004] Howeve...
