An adjustable dental device for use with a CPAP system in the treatment of sleep apnea and snoring is comprised of an upper bite block, a lower bite block having one or more tongue retainers, means for adjustably connecting the upper bite block to the lower bite block, and means for connecting the dental device to a CPAP system. The adjustable dental device is compatible with a variety of CPAP systems, including systems that utilize nasal inserts and systems that utilize a nasal mask.

Adjustable dental device for treatment of sleep apnea and snoring

A device for responding to touch discrimination comprises an array of optical fibers distributed over a supporting substrate and a UV holographic processor is connected to the fibers rendering the fibers capable of responding to touch discrimination and location identification. The substrate is an artificial limb having the array of optical fibers thereon that have a density substantially similar to that of the human body. Wavelength comparators are associated with the optical fibers, the wave length comparators providing numerous sensing locations in a single fiber strand as part of a complete fiber optic network for mechanical actuation and sensory feed back.

Process to create artificial nerves for biomechanical systems using optical waveguide network

An evanescent filed based sensor uses a detector for sensing variations in properties of a fluid flowing in a boundary layer adjacent to the detector. The detector comprises an optical waveguide in the form of an optical fiber having a core layer covered by a cladding layer and having a substantially D-shaped cross section defining a planar surface with an optical grating pattern thereon. When a beam of laser light is directed through the detector as an input, variations in an output of the beam of laser light are indicative of changes in fluid pressure or density in the boundary layer or immediate region adjacent to the grating of the optical waveguide.

Apparatus for and methods of sensing evanescent events in a fluid field

Apparatus for and methods of providing Bragg reflection filters in a receptor such as an optical fiber uses a wavelength tunable phase mask made of a non-linear material into which an interference pattern is written by a pair of converging laser light beams. The interference pattern is probed with a reading beam of laser light that creates diffraction orders which are read into the receptor. By changing the wavelength and amplitude of the writing beams that create the interference region in the phase mask, the characteristics of the Bragg reflection filter written into the optical fiber can be changed. Accordingly, if the optical fiber is indexed along the wavelength tunable phase mask while the characteristics of the interference region are changed, thousands of different Bragg reflection filters can be formed in a single optical fiber.

A Bragg reflection filter wavemeter is used to measure transverse holographic gratings and optical fibers and utilizes a first interferometer which is always fixed with respect to the optical fiber and a second adjustable interferometer. The optical fiber and first interferometer are mounted on a translating support while the second interferometer includes a pair of angularly adjustable mirrors for changing the angle at which the object and reference beams thereof intersect the fiber. Since the fiber is mounted on a movable support, the position of the support can be continually adjustable so that the reference and object beams always intersect the fiber at the same point, regardless of the angle assumed by the reflecting mirrors. The resulting interference patterns are projected by an objective lens to the far field in which a linear scanning, photodiode array is moved. The photodiode array includes a first photodiode which is sensitive only to the interference patterns from the first laser beam and a second photodiode sensitive to the interference patterns from the second laser beam. The photodiodes are connected to a counter which provides ratios of interference line counts which are then multiplied by wavelength to provide precise modulation spacings so as to establish wavelength standards.
