An inflatable membrane for use with a three-dimensional (3D) scanning system configured to measure signal intensity of a first and a second wavelength of light may include a matrix material, a pigment for opacity, and a fluorescent material that is transparent to the first and the second wavelengths of light. The first and second wavelengths of light may be ranges of wavelengths. The matrix material may include a silicone, and the pigment for opacity may include a carbon black. The 3D scanning system may be configured to scan anatomical cavities, such as the human ear canal.

Inflatable membrane for fluorescent imaging and improvements in dye materials

Disclosed are embodiments of an articulating tool having a head that articulates and is capable of maintaining an angle for drilling or placing a fastener into a bone. The articulating tool includes a housing, an articulating head, a rotatable drive shaft, and a driver tip connected to the distal shaft portion. The articulating tool may be constructed and arranged to move between a first position and a second position, wherein in the first position and the second position the articulating head and the rotatable drive shaft are at different angles with respect to the longitudinal axis of the housing.

Articulating tool and methods of using

In one aspect, there is provided an apparatus. The apparatus may include a balloon membrane. The balloon membrane may include an opening, an exterior surface, and an interior surface. The interior surface may include one or more fiducial markers forming a pattern detectable by a scanner imaging the interior surface of the balloon membrane. Scanned portions of the interior surface of the balloon membrane may be combined based on the fiducial markers forming the pattern. Related methods and articles of manufacture, including computer program products, are also disclosed.

Fiducial markers for fluorescent 3D imaging

Methods, apparatus, and systems are provided for scanning and measuring an anatomical cavity. An apparatus may include an absorbing medium assembly that is fluidly connected to an earpiece and configured to provide an absorbing medium to the earpiece. The absorbing medium assembly may include a medium container with a gas trap, as well as a tube fluidly connected to the medium container. The gas trap may be located at a top portion of the medium container. The tube may be coupled to the top portion or a bottom portion of the medium container. The system may include a dip tube disposed inside the medium container when the tube of the absorbing medium assembly couples to a top portion of the medium container. A gas relief valve configured to enable gas to escape may also be present in the apparatus.

Air removal and fluid transfer from a closed system

Some embodiments include a privacy/security apparatus for a portable communication device that includes a housing assembly configured to at least partially attenuate at least one of sound energy, acoustic energy, and electromagnetic energy including light, optical, and IR energy and RF radiation from passing through the housing assembly. The housing assembly includes a Faraday cage with two or more portions, and at least one protective shell coupled to or forming at least one aperture. The at least one aperture is configured and arranged to at least partially enclose the portable communication device so that at least a portion of the portable communication device is positioned within at least one portion of the Faraday cage, and the at least one seal coupled or integrated with the protective shell. The housing assembly can be an articulating assembly, a sliding assembly, and can include an active acoustic jamming or passive acoustic attenuation element.

Privacy and security systems and methods of use

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.

Selecting an earpiece based on dynamic data

Various improvements to inflatable membranes for use in three-dimensional imaging of interior spaces are disclosed. These improvements include, among other things, equipping the inflatable membrane with desirable optical features, such as fiducials, optical coatings, etc., that can be used to improve data acquisition.

Evaluating fit of an earpiece based on dynamic data

Various improvements to three dimensional imaging systems having inflatable membranes are disclosed. These improvements include, among other things, a proximity sensor that can be used to warn a user of the device when approaching a feature in a cavity, such as an eardrum in an ear canal; or optical sensors with an optical coating matching the refractive index of the medium in which the optical sensors are deployed, to improve data acquisition.

Enhanced sensors in three dimensional scanning system

Various improvements to inflatable membranes are disclosed. These improvements include, among other things, features on the membrane that can mitigate hazards such as bubble formation or frictional damage during inflation of the membrane.

Inflatable membrane with hazard mitigation

Various improvements to inflatable membranes are disclosed. These improvements include techniques for advantageously controlling the inflation of a membrane within a cavity, such as a human ear canal.

Inflatable membrane having non-uniform inflation characteristic

A method for assembling parts. A sealant is placed between a plurality of parts in a stack up to form a workpiece. The workpiece is clamped using a permanent magnet unit and an electromagnetic clamping device in an activated state such that a number of forces caused by a magnetic field clamps the workpiece between the electromagnetic clamping device and the permanent magnet unit. A number of holes are drilled in the workpiece. A number of fasteners are installed in the number of holes.
