Abstract: Systems and methods for viewing stereoscopic video images are disclosed. The systems can include a first video camera configured to generate a first video feed of a subject, and a second video camera configured to generate a second video feed of the subject. The first video feed and the second video feed combined generate a near real-time stereoscopic video image. A tracking module can be associated with the first video camera and the second video camera, and can be configured to cause the first video camera and the second video camera to be directed to a desired convergent point relative to a selected tracking point to maintain stereopsis. The system may further include an array of video cameras, a gesture control module, an image adjustment module, a calibration module, or a 3-D modeling module, for example.

Abstract: Cheek and lip expansion devices including an upper frame portion configured to extend about an upper dental arch, and a lower frame portion configured to extend about a lower dental arch. The upper and lower frame portions may each include first and second side members, each with anterior and posterior regions. An upper connecting member may extend between the anterior regions of the upper side members. A lower connecting member may extend between the anterior regions of the lower side members. The posterior regions of the upper and lower side members on respective sides of the frame are joined to one another to form a bendable radius that resists bending at a distinct point. The bendable radius on opposed sides permits the frame to be collapsed top to bottom. The frame may be collapsible side-to-side. A posterior crossbar may be provided extending between the posterior regions of the side members.

Abstract: Cheek retraction devices including an upper frame element configured to bear against and retract soft oral tissue from one or more teeth of an upper dental arch, a lower frame element configured to bear against and retract soft oral tissue from one or more teeth of a lower dental arch. The upper and lower frame elements may each include left and right frame portions wherein the upper and lower left frame portions are joined to one another to form a v-shaped hinge on one side of the frame, while upper and lower right frame portions are joined to one another to form a v-shaped hinge on another side of the frame. The v-shaped hinges on opposed sides permit the upper and lower frame elements to be at least partially folded toward each other. A posterior frame element may be provided extending between the v-shaped hinges.

Abstract: Systems and methods for viewing stereoscopic video images are disclosed. In one example, a stereoscopic video imaging and tracking system can include a first video camera to generate a first video feed of a subject, and a second video camera spaced a distance from the first video camera to generate a second video feed of the subject, wherein the first video camera and the second video camera are directed toward a convergent point to provide a stereoscopic image of the subject. The system can also include a tracking system to cause the first video camera and the second video camera to follow a tracking point to maintain stereopsis of the subject, and a zooming device associated with the first video camera and the second video camera. The zooming device can provide variable magnification of the stereoscopic video image.

Abstract: Systems and methods for viewing stereoscopic video images are disclosed. One system comprises a first video camera configured to generate a first video feed of a subject. A second video camera is spaced a pupilary distance from the first video camera and configured to generate a second video feed of the subject. A tracking module associated with the first video camera and the second video camera is configured to cause the first video camera and the second video camera to be directed to a desired convergent point relative to a selected tracking point to maintain stereopsis. A zooming module associated with the first video camera and the second video camera is configured to provide a desired magnification of the near real-time stereoscopic video image.

Abstract: Systems and methods for video interaction between physical locations are disclosed. The systems can include a first room having a plurality of video cameras and a second room having a plurality of motion detection cameras. A marker located in the second room can be detected by the plurality of motion detection cameras whereby location coordinates can be calculated for the marker. A relative position of the marker in the first room can be determined using the location coordinates. A video feed from the first room can be identified that provides a perspective of the first room based on the relative position of the marker and the video feed can be provided to a display located in the second room.

Abstract: Oral treatment devices formed from wax-based compositions that are thermally stable when formed into a three-dimensional shape to a temperature of at least 45° C. and plastically deformable at room temperature (25° C.). The wax-based compositions include a wax fraction homogeneously blended with a polymer fraction. The wax fraction includes at least one wax. The polymer fraction includes at least one polymer selected such that, when the wax and polymer are homogeneously blended together, they yield a wax-based composition having the desired properties of thermal stability and plastic deformability. Oral treatment devices are dimensionally stable to a temperature of at least 40° C. without external support and can be plastically deformed in a user's mouth to become at least partially customized to the size and shape of user's unique dentition and/or an appliance in a user's mouth.

Abstract: A hollow syringe barrel for use in syringe mixing systems for mixing a two-component composition. A hollow body of the syringe barrel includes a proximal end, a distal end, and continuous cylindrical wall defining an internal chamber for containing a first component. A rupturable membrane disposed at the distal end caps and seals off a single dispensing orifice. A second syringe barrel can be coupled to the distal end of the hollow syringe barrel to form a syringe-to-syringe mixing system. First and second plungers disposed within the hollow syringe barrel and second syringe barrel, respectively, are used to mix and cycle back and forth first and second components initially contained within the hollow syringe barrel and second syringe barrel. The two components are initially separated by the rupturable membrane, which is irreversibly ruptured by applying sufficient pressure to the first plunger within the hollow syringe barrel prior to mixing.
