Abstract
A portable physical agents directive (PAD) dosimeter system may be provided. The portable PAD dosimeter system may include a housing and at least one accelerometer configured to generate electrical signals corresponding to a vibration exposure of an operator of a work machine. The portable PAD dosimeter system may also include a controller disposed in the housing configured to process the electrical signals and to determine whether the vibration exposure is above a predetermined threshold.
Claims22
A portable physical agents directive (PAD) dosimeter system, comprising:
- a housing;
- at least one accelerometer configured to generate electrical signals corresponding to a vibration exposure of an operator of a work machine;
- and
- a controller disposed in the housing configured to process the electrical signals and to determine whether the vibration exposure is above a predetermined threshold.
A portable physical agents directive (PAD) dosimeter system, comprising:
- a housing configured to be selectively mounted on a part of a work machine;
- at least one accelerometer mounted inside the housing to generate electrical signals based on vibrations experienced by the housing, which correspond to a vibration exposure of an operator of the work machine;
- and
- a controller contained in the housing and configured to process the electrical signals and to determine whether the vibration exposure is above a predetermined threshold.
A method for determining PAD compliance of a work machine, comprising:
- mounting a portable PAD dosimeter on a part of the work machine;
- using the portable PAD dosimeter to measure whole body vibration exposure of an operator of the work machine and to generate measurement data;
- and
- determining whether the whole body vibration exposure is above a PAD whole body vibration threshold.
A work machine, comprising:
- an engine configured to provide power to the work machine;
- a portable physical agents directive (PAD) dosimeter fitted to the work machine, the portable PAD dosimeter including:
- at least one sensor to generate electrical signals corresponding to a vibration exposure of an operator of the work machine, and
- a controller configured to process the electrical signals and to determine whether the vibration exposure is above a PAD threshold;
- and
- an on-board control system coupled with the portable PAD dosimeter via a data link to exchange information with the portable PAD dosimeter.
