Using dynamic data to determine a material profile for earpiece

摘要

The attenuation and other optical properties of a medium are exploited to measure a thickness of the medium between a sensor and a target surface. Disclosed herein are various mediums, arrangements of hardware, and processing techniques that can be used to capture these thickness measurements and obtain dynamic three-dimensional images of the target surface in a variety of imaging contexts. This includes general techniques for imaging interior/concave surfaces as well as exterior/convex surfaces, as well as specific adaptations of these techniques to imaging ear canals, human dentition, and so forth.

主权项

1. A method comprising:
providing a library of a plurality material types available for use in a fabrication process, each of the plurality of material types characterized by elasticity; obtaining static data from an ear canal of a subject, the static data including a three-dimensional image of a surface of the ear canal at a predetermined pressure; obtaining dynamic data from the ear canal of the subject, the dynamic data including data from the ear canal characterizing changes in a shape of the ear canal related to at least one of a compliance of the ear canal to changes in pressurization or a shape change of the ear canal in response to a musculoskeletal movement of a head of the subject; calculating a shape for an earpiece based upon the static data; and calculating a material profile for the earpiece based upon the dynamic data using one or more of the plurality of material types of the library.
