Abstract
An apparatus according to one approach includes a module having an array of transducers having at least two transducers. The apparatus also includes a persistent memory having stored therein data of a span of the array of transducers at a particular temperature. An apparatus according to another approach includes a module having fiducials at known positions relative to an array of transducers. The apparatus also includes a persistent memory having stored therein data of a span between the fiducials at a particular temperature. The fiducial span may be used in conjunction with the known locations of the fiducials relative to the array to characterize the span of the array.
Claims25
An apparatus, comprising:
- a module having an array of transducers having at least two transducers;
- and
- a persistent memory having stored therein data of a span of the array of transducers at a particular temperature and data of a target span of an array of transducers at the particular temperature.
An apparatus, comprising:
- a plurality of modules, each module having an array of transducers having at least two transducers;
- and
- a persistent memory having stored therein data of spans of the arrays of transducers at a particular temperature and data of a target span of each array of transducers at the particular temperature.
An apparatus, comprising:
- a module having fiducials at known positions relative to an array of transducers;
- and
- a persistent memory having stored therein data of a span between the fiducials at a particular temperature and data of a target span between the fiducials at the particular temperature.
