Abstract: The present invention relates to a therapeutic device for the non-invasive treatment of human or animal bodies. Particularly, though not exclusively, the invention relates to a therapeutic device that selectively emits and maintains an energy field (electrostatic field, pulsed electromagnetic field or ultrasonic field) within a preselected frequency range for the effective alleviation of pain, inflammation and/or an alternative treatment. The device comprises an electronic circuit including a frequency generator for selectively producing electrical signals. The electronic circuit comprises a toroidal coil that is adapted to produce an oscillating electromagnetic field within a preselected frequency range in response to energisation by said electrical signals. The electronic circuit is constructed and arranged to adjust the electrical signals produced such that the coil selectively maintains the pulsed electromagnetic field within the preselected frequency range. The coil may be detachable.

Abstract: A technique for investigating the accuracy of fitment for a vehicle replacement windscreen having a mounted driver assistance camera (DAC) utilises an illuminating radiation delivery device and a spectral reflection profile from the DAC is imaged and compared to a datum spectral reflection profile (SRP). The datum spectral reflection profile may result from a DAC fitted to the windscreen before replacement. A first spectral reflection profile may imaged with DAC in position on a damaged windscreen fitted to the vehicle and a second spectral reflection profile is imaged with DAC in position on the replacement windscreen fitted to the vehicle.
