ACCELEROMETER ASSEMBLY AND THE USE THEREOF

摘要

An apparatus for detecting the movement of a body is provided, the apparatus comprising three accelerometers, each accelerometer having an axis, the accelerometers being arranged such that the axes of the three accelerometers lie in a single plane or in parallel planes and are fixed in relation to a point, the accelerometers being arranged about the point to have their axes extending at non-zero angles to each other. In a preferred arrangement, the apparatus comprises a plurality of two-axes accelerometers, a first accelerometer being arranged to detect movement along each of a first pair of orthogonal axes, the second accelerometer being arranged to detect movement along each of a second pair of orthogonal axes, the orthogonal axes of the second accelerometer extending at an angle to the orthogonal axes of the first accelerometer. A method of detecting an analysing movement is also disclosed. The apparatus and method find wide application, for example in the analysis and correction of abnormalities in a persons gait, for example by functional electrical stimulation.
