Abstract: A system for evaluating a document for the purpose authorizing an individual presenting the document for a transaction. The system comprises means for acquiring data from the document presented by the individual and for acquiring biometric data characteristics of the individual at the time of the transaction. The system uses data processing means to compare the acquired data to reference data stored in databases containing records corresponding to various types of documents and records characterizing the individuals to whom documents were issued. The system retrieves the biographical information corresponding to the individual seeking authorization and determines whether the information indicates that the individual is eligible for the transaction. The system stores information identifying authorization attempts and information identifying associated transaction. The invention additionally comprises a method following the stated functions of the system.

Abstract: An electromechanical translation apparatus comprising a driven member which is adapted to be incrementally moved in a selected direction, and a piezoelectric multiaxis micropositioner adapted to produce incremental movement of the driven member in the selected direction wherein the micropositioner includes a mounting means, at least one piezoelectric driver assembly having a housing, an engaging member formed of a hard material having a selected driving end at one end thereof and a driven end at the other end wherein the engaging member's one end is positioned to selectively engage and translate said driven member in response to a driving force, and at least three piezoelectric driver elements positioned between the driven end of the engaging member and the housing wherein the piezoelectric driver elements are positioned in a spaced, angular relationship to the others and wherein each piezoelectric driver element is capable of separately responding to an electrical signal having a predetermined frequency and
