Abstract
Methods and apparatus for monitoring the content of a medicine bottle via electrical capacitive tomography (ECT) are presented in which the three-dimensional volume of the medicine bottle, and its content, are imaged by developing a map of its permittivity. The permittivity map is developed by applying a stimulus between two of a plurality of electrodes that are arranged about a chamber of the medicine bottle in which the content is contained, and measuring an electrical response at each of the remaining electrodes of the plurality. By repeating this process for every pair of electrodes within the plurality, a complete permittivity map of the three-dimensional volume is developed. Once the permittivity map is established, the number and type of tablets (or liquid) within the volume is determined.
