Abstract

The present invention relates to a device which can measure, induce, and correct perturbations acting on an electromagnetic (EM) propagation source. Piezoelectric transducers are used to measure and control perturbations within a system to improve operation of an EM source. Perturbation measurements can be used to determine the environmental and system impacts on the EM source. Moreover, measurements can be used to correct or nullify perturbations applied to the EM source, through active or passive means.

First claim

a vibration sensing system comprising:
a plurality of piezoelectric transducers (PTs) each comprising a piezoelectric material (PM) and an adjuster, wherein the plurality of PTs is disposed within the second cavity section such that each PM contacts the interior wall section and each adjuster contacts the exterior wall section, wherein extending the adjusters of the plurality of PTs moves the interior wall section such that the volume of the first cavity section decreases; and

a system controller, wherein the system controller is electrically coupled to the vibration sensing system;
wherein the system controller is configured to activate the plurality of PTs after an EM source is placed within the first cavity such that at least one adjuster of the plurality PTs extends to move the interior wall section so that the interior wall section is flush with the EM source;
