Abstract
A method of determining information about a device includes the steps of 1) acquiring an image of at least a portion of the device, 2) comparing the information content of the image to the information content of at least one record of a library, and, 3) if the comparison is positive, reporting that the device is in the possible state represented by the library record. A method which depends on calculations based on the acquired image rather than on comparison of the information content of the image to the information content of one or more library records is also disclosed. A system for determining the state of the device is also disclosed.
