Abstract
A memory means is provided which is adapted to be mounted integral with the transducer element used in a transducer system. The memory may store nonlinearity error information or other information concerning errors in the positioning or scan control for the particular transducer, which information may be utilized by the transducer system to compensate for such errors. The memory may also be utilized to store selected information concerning the measured output characteristics of the transducer element which may be utilized by the transducer system to assure that a desired output level is achieved from the transducer element or that the output otherwise is in conformance with that desired. One or more bytes may be provided in the memory which may be utilized to inhibit use of the associated transducer element for particular fields of use or classes of service. The memory element may also store other selected information concerning the particular transducer element, including various operating constants for the element, which information may be utilized by the transducer system to control the operation of the transducer element, to evaluate responses obtained from the transducer, for …
