Abstract: Parathyroid adenomas may be identified using optical probes which distinguish the diseased tissue from adjacent healthy tissue. Spectroscopic properties of the tissue may be used to distinguish healthy from diseased tissue. Traditional surgery to remove the parathyroid adenoma may be avoided by using techniques to occlude the blood supply to the diseased tissue. Occlusion may be accomplished by applying energy to the blood vessel such as with radiofrequency energy, ultrasound energy or laser energy. Cryogenic probes may also be used to occlude the blood flow. Clips, sutures or other mechanical mechanisms may also be used to occlude the flow, thereby destroying the diseased tissue.

Abstract: A device provides incident light on oral structures, switchably between two states. In the first state, incident light causes autofluorescence of byproducts of decay, and an optical filter between the oral structures and either the user's eyes or a visualizing apparatus yields visually distinguishable appearances for that autofluorescence depending on whether the tissue is healthy or unhealthy. In the second state, the incident light is of a color composition that yields a substantially “white” spectrum after passing through the filter.

Abstract: An implantable sensor array incorporates active electronic elements to greatly increase the number of sensors and their density that can be simultaneously recorded and activated. The sensors can be of various configurations and types, for example: optical, chemical, temperature, pressure or other sensors including effectors for applying signals to surrounding tissues. The sensors/effectors are arranged on a flexible and stretchable substrate with incorporated active components that allow the effective size, configuration, number and pattern of sensors/effectors to be dynamically changed, as needed, through a wired or wireless means of communication. Active processing allows many channels to be combined either through analog or digital means such that the number of wires exiting the array can be substantially reduced compared to the number of sensors/effectors on the array.

Abstract: A system and method for using near-infrared or short-wave infrared (SWIR) sources such as lamps, thermal sources, LED's, laser diodes, super-luminescent laser diodes, and super-continuum light sources for early detection of dental caries measure transmission and/or reflectance. In the SWIR wavelength range, solid, intact teeth may have a low reflectance or high transmission with very few spectral features while a carious region exhibits more scattering, so the reflectance increases in amplitude. The spectral dependence of the transmitted or reflected light from the tooth may be used to detect and quantify the degree of caries. Instruments for applying SWIR light to one or more teeth may include a C-clamp design, a mouth guard design, or hand-held devices that may augment other dental tools. The measurement device may communicate with a smart phone or tablet, which may transmit a related signal to the cloud, where additional value-added services are performed.

Abstract: In an embodiment, an apparatus for opto-acoustic imaging includes a first contact area adapted to apply a first pressure to a surface of an imaging volume of a subject and a second contact area adapted to apply a second pressure to the surface. The second contact area is configured to provide decreased blood exit from the imaging volume by restricting flow relative to the first contact area. An optical energy output port is provided to illuminate the imaging volume to produce opto-acoustic signals from an absorbed optical energy of blood in the imaging volume. The opto-acoustic signals are detected by one or more ultrasound transducers and processed by a processor to generate images of the volume. An image generated by processing the detected opto-acoustic signals is output on a display.

Abstract: An apparatus and method that utilizes thermal dilution to detect a wide range of flow rates and/or flow status in cerebrospinal fluid (CSF) shunt systems. The use of a large cold source in combination with thermosensor pad of a particular construction provide a fluid flow analyzer with the ability to detect very low levels of CSF flow. In addition, a method for adjusting thermal dilution readings to compensate for varying shunt catheter depth is shown and for determining a steady state of the thermal dilution readings. The thermosensor pad is conformable to a patient's skin contour thereby making the apparatus and method less sensitive to ambient temperature errors and, as a result, more accurate in assessing CSF flow. Furthermore, a software error check is provided for identifying poor sensor-to-skin contact for alerting an operator to re-apply the thermosensor pad to correct, as well as a post-test check to determine if temperature data is reasonable before determining flow status or flow rate.

Abstract: This invention provides a system and method for determining a user's Current System State so as to enhance balance and well-being. A determination process computes force vector values based upon questions and integration of other biological measurements provided via a user interface.

The representation defines a three-dimensional volume and the force vector values are arranged in three-dimensions. The user's Natural System State is located at a location in the volume and the Current System State is at another location. The force vector values are each illustratively represented as a discrete color spectrum. Users access the system through a client interconnected through the Internet.

Abstract: A portable electronic device uses the initial heartbeat value to calculate a possible heartbeat variation. Then a reference range is determined. Only the real time heartbeat value falling in the reference range is output as a correct real time heartbeat value. Thus, the too large or too small erroneous heartbeat values influenced by the vibration noise are eliminated to precisely output the correct real time heartbeat value. Therefore, the extra vibration sensors need not to be installed to lower the cost and to reduce the volume.
