    摘要: The present invention provides a method for measuring a blood analyte concentration of a body part comprising removing a portion or all of the blood from the body part to produce a modified body part, and recording a first absorbance value of the modified body part. This is followed by filling the body part with blood to produce a filled body part, and recording a second absorbance value of the filled body part. A difference spectrum is obtained by subtracting the first absorbance values from the second absorbance values, and a calibration algorithm for the blood analyte is applied to the difference spectrum, thereby measuring the concentration of the blood analyte. Also provided is an apparatus for determining the concentration of a blood analyte of a body part. The apparatus comprising a chamber of a size and shape to receive the body part, where the chamber comprises an element for withdrawing and reintroducing blood from the body part, when the body part is inserted within the chamber. The chamber also comprising one or more than one port for introducing electromagnetic radiation into the chamber and onto that body part, and collecting remaining electromagnetic radiation following interaction with the body part.

    摘要: The invention relates to methods of measuring the overall elasticity of skin and determining the portion of the overall elasticity that is due to elastic properties and the portion of overall elasticity that is due to viscoelastic properties of the skin and correlating the results of the measurement to an individual's chronological age. The invention also relates to methods of measuring improvements in a person's skin health by measuring elasticity before, during and after human clinical trials of topical and/or oral treatment compositions. The parameters for determining elasticity are based on areas that are defined on a deformation/relaxation curve and require that an inflection point be determined for each skin sample analyzed.

    摘要: A method for testing the effect of a skin care product includes measuring a mechanical property of skin tissue using nonlinear stochastic system identification, applying the product to the skin, repeating the measurement of the mechanical property after the application of the product, and comparing the before and after measurements to quantify the effect of the product.Measuring the mechanical property of the skin can include placing a probe against a surface of the skin, perturbing the skin with the probe using a stochastic sequence, and measuring the response of the skin to the perturbation. Perturbing the skin can include indenting the skin with the probe, extending the skin with the probe, and sliding the probe across the skin surface. The mechanical property may be indicative of skin compliance, skin elasticity, skin stiffness, or skin damping. The mechanical property can be dependent on perturbation depth and may be measured at a plurality of anatomical locations.

    摘要: An invention is disclosed for locating a region of interest (ROI) in the radius. A method and apparatus are disclosed that use a pair of ultrasound transducers for ultrasound assessment of various properties of bone. The invention includes positioning the transducers on the anterior-posterior (dorsal and ventral) sides of a forearm of an individual. The positioning is based on the forearm length, and a selected percentage of this length at which the ROI is desired. In a presently preferred embodiment of the invention, the ROI is defined as the ⅓rd location. An arm is placed in an ultrasound fixture which has a first surface, a second surface with a raised portion against which the ulna styloid process is placed, and a third surface on which the elbow is placed. The distance between the raised portion of the second surface and the centerlines of the pair of ultrasound transducers is adjustable. The positioning so obtained leads to the ability to make both (i) reproducible measurements and (ii) to be able to compare the results obtained in one person with another, because relatively analogous portions of the radii are assessed in both. In an alternative embodiment of the invention, a single transducer is positioned similarly on the forearm, operating in pulse-echo mode.
