  • Patent number: 6387156
    Abstract: A filtration system, includes a filtration unit and processor. The filtration unit operates to filter ablative particles generated by thermal imaging of media and transmits a signal corresponding to a parameter, such as a pressure or pressure differential, representing a current state of the operation of the filtration unit, such as the state of the filters, during the filtering of the ablative particles. The processor receives the transmitted signals and generates, responsive to the receipt of the transmitted signal, a signal representing operator information associated with the current state operation, such as a warning or instructions for correcting a deficiency, and/or a signal to stop the imaging of the media.
