Abstract: The present disclosure provides an intraoral adapter comprising: an elongated housing comprising a viewing channel between a proximal portion and a distal portion of the elongated housing, wherein the viewing channel is configured to define a field of view of an intraoral region of a subject's mouth; and a connector configured to interchangeably accept and hold one or more external modules.

Abstract: The intraoral imaging system described herein may comprise an intraoral adapter. The intraoral adapter may be operably coupled to a mobile device. The intraoral adapter may comprise an elongated housing comprising a viewing channel. The viewing channel may define a field of view of an intraoral region of a subject's mouth for intraoral scanning using a camera of a mobile device. The elongated housing may comprise a flange that is positioned outside of the field of view of the intraoral region of the subject's mouth. The intraoral imaging system may further comprise an image processing unit configured to (i) process a plurality of intraoral images and/or videos captured using the camera of the mobile device, and (ii) determine a dental condition of the subject based at least in part on the plurality of intraoral images and/or videos.

Abstract: A transducer is provided that converts energy between two forms using active components. The transducer also includes passive components in contact with the active components that perform passive component functions separate from the energy conversion function. The passive components include ferrofluids and have elastic properties that are modifiable by exposure of the passive component to a magnetic field to selectively control the energy conversion function.
