Abstract: A method of detecting at least a partial blockage in a porous member separating an inner chamber of a device having a gas sensor responsive to an analyte positioned within the inner chamber and an ambient environment includes emitting pressure waves within the inner chamber and measuring a response via a sensor responsive to pressure waves positioned within the inner chamber.

Abstract: A method of detecting at least a blockage status in a porous member separating a measurement chamber of a device including a gas sensor positioned within the measurement chamber which is responsive to an analyte in an ambient environment to be sampled, includes emitting pressure waves from a pressure wave source which travel within the measurement chamber, measuring a first response via a first sensor responsive to pressure waves positioned at a first position within the measurement chamber, measuring a second response via a second sensor at a second position, different from the first position, and in fluid connection with the pressure wave source, determining the blockage status of the porous member based upon a functional relation of the first response and the second response.

Abstract: A system includes a two-conductor loop in which the loop current or current signal is controlled by a loop current controller to be proportional to a signal output from a sensor. The system further includes energy harvesting circuity in electrical connection with the two-conductor loop which includes a second current controller in parallel electrical connection with the loop current controller and a power converter in electrical connection with the second current controller. The second current controls a portion of current drawn from the two-conductor loop and delivered to the power converter from an output port thereof. The portion of the current drawn from the two-conductor loop is returned to the loop current controller from the energy harvesting circuit. Noise in the portion of the current drawn from the two-conductor loop by the second current controller is controlled by the second current controller to be below a predetermined threshold.
