Abstract

A portable device is held between the fingers of one hand and measures the exposure of an operator to vibration from a tool handle 1D. The device comprises a stem or neck 3B which joins two relatively wide portions. The stem fits between the operators fingers. One of the two wide portions 1A,3A (the module) sits on top of the hand, across the back of the fingers, and contains a battery and a processor for conditioning and recording signals from vibration sensors. The other wide portion 1C,3C (the foot) sits under the fingers, on the palm side of the hand, and is held in contact with the tool handle 1D in use. The device contains acceleration sensors for measuring vibrations along orthogonal Cartesian axes. At least the component of acceleration that occurs parallel to the direction of the top of the fingers is measured using a sensor 3H in the foot. Measuring this component of acceleration in the foot rather than in the module means that any rotation of the device about the line of contact 1F with the handle 1D does not result in spurious vibration readings.
