摘要:
An apparatus and method for non-invasive determination of attributes of human tissue by quantitative infrared spectroscopy. The system includes subsystems optimized to contend with the complexities of the tissue spectrum, high signal-to-noise ratio and photometric accuracy requirements, tissue sampling errors, calibration maintenance problems, and calibration transfer problems. The subsystems include an illumination subsystem, a tissue sampling subsystem, a spectrometer subsystem, a data acquisition subsystem, and a processing subsystem. The invention is applicable, as examples, to determining the concentration or change of concentration of alcohol in human tissue.
摘要:
A mucosal formulation for administration to mucosal membranes, such as in the mouth, nasal passage, stomach, vagina, etc., is disclosed. The mucosal formulation contains a lipid-pharmaceutical agent complex formed from phospholipids possessing a hydrophobic moiety that orients into a hydrophobic phase and a polar head moiety that orients towards the aqueous phase (i.e., “amphipathic” lipids). When placed in an aqueous medium (e.g., vaginal fluid), the phospholipids form liposomes or other small lipid vesicles (e.g., micelles) that may then be used to deliver pharmaceutical agents into a living organism.

摘要:
A method of providing power and/or data to a seat in a seating area. A power distribution system having a continuous power bus is used to supply power and/or data to seats in a mobile platform or fixed structure. The power distribution system generally includes a bus strip that, in a mobile platform, extends along a length of a passenger cabin and a connector operable to provide a connection between the bus strip and the passenger seats. Power and/or data can be transmitted between the bus strip and the passenger seats, via the connector, at any point along the bus strip, thus eliminating the need to run separate connections between the power and/or data source and each seat.
摘要:
A DC-to-DC converter comprises a converter section and a controller section. The converter section comprises a primary section and a secondary section. The primary and secondary section includes MOSFET switches. The controller section is coupled to the converter section and comprises a pulse width modulation (PWM) section and a delay section. The PWM section comprises an error amplifier configured to generate an error signal representative of a variance between an output voltage of the converter section and a reference voltage and a PWM configured to produce a PWM signal based on the error signal. The delay section comprises of delay circuits configured to generate delayed output signals from the PWM signal and power switching device drivers coupled to the delay circuits and configured to receive the delay output signals and generate a controlled signals to control the on/off state of the MOSFET switches.
摘要:
A method of treating a dental patient includes applying ultraviolet C radiation to the mouth of the patient for a time and at a proximity and intensity sufficient to have a bacteriocidal effect. With this method, the risk of bacterial infection to both the patient and the dentist/oral surgeon can be reduced.
摘要:
A method of detefnnining a measure of a tissue state (e.g., glycation end-product or disease state) in an individual. A portion of the tissue of the individual is illuminated with excitation light, then light emitted by the tissue due to fluorescence of a chemical with the tissue responsive to the excitation light is detected. The detected light can be combined with a model relating fluorescence with a measure of tissue state to determine a tissue state. The invention can comprise single wavelength excitation light, scanning of excitation light (illuminating the tissue at a plurality of waveliengths), detection at a single wavelength, scanning of detection wavelengths (detecting emitted light at a plurality of wavelengths), and combinations thereof. The invention also can comprise correction techniques that reduce determination errors due to detection of light other than that from fluorescence of a chemical in the tissue. For example, the reflectance of the tissue can lead to errors if appropriate correction is not employed. The invention can also comprise a variety of models relating fluorescence to a measure of tissue state, including a variety of methods for generating such models. Other biologic information can be used in combination with the fluorescence properties to aid in the determination of a measure of tissue state. The invention also comprises apparatuses suitable for carrying out the method, including appropriate light sources, detectors, and models (for example, implemented on computers) used to relate detected fluorescence and a measure of tissue state.
