A wearable band configured to fit human limbs receives muscle tension data via sensors housed within the device. The processing circuitry generates statistical models for each physical state of a user and compares the received data with the statistical model. The user is alerted when the processing circuitry detects a change in the data that is outside the predetermined range. The sampling rate of measurements increases when a change is detected to confirm the abnormal data.

Wearable device and method for monitoring muscle tension and other physiological data

An apparatus for attenuating the intensity of light transmitted through the apparatus is provided. In one embodiment, the apparatus may comprise a first polarizer having a first polarizing orientation and a second polarizer having a polarizing orientation perpendicular to the first polarizer. First and second electrodes are disposed between the polarizers and a nematic liquid crystal layer is disposed between the electrodes. At least one light detector positioned for measuring the intensity of the transmitted light may be positioned on an outer side of the second polarizer. A voltage controller in electrical communication with the light detector is provided for controlling the voltage level applied to the electrodes based on the intensity of the measured light wherein the voltage determines the amount of light transmitted through the apparatus.

A probe for a system for determining the chemical signature of a pharmaceutical compound. The probe comprises: a housing; an inlet in the housing adapted to be connected to a transmitting optical fiber; a scanning aperture in the housing; a receiving outlet in the housing adapted to be connected to a receiving optical fiber; at least one transmission reflector positioned in the housing to receive laser light from the transmitting optical fiber and reflect the laser light through the detection outlet to a pharmaceutical vial containing a pharmaceutical compound positioned outside the housing, and at least one receiving reflector positioned in the housing to receive light reflected by the pharmaceutical compound and reflect the light to the receiving outlet. This configuration can enable rapid and accurate scanning of a pharmaceutical contained in a vial positioned adjacent the detection outlet.

Laser-induced breakdown spectroscopy with second harmonic guide light

A process for detecting HIV infection, Hepatitis A, B and C, and other similar infections in a plasma sample, wherein the process involves the use of an excitation laser source to irradiate upon the plasma sample an excitation laser beam to obtain a fluorescence emission spectrum of the plasma sample. The invention uses an excitation laser wavelength of about 355 nanometers. Detection of the fluorescence is made in the wavelength range from about 380 to 600 nanometers. The resulting spectrum of the sample is compared with the spectrum of a control which is free from infection. Analysis of the parameters of the emission spectra including, but not limited to, peak intensity wavelength, amplitude at the peak intensity, area ratio of left and right portions of the emission spectra, and shifts of the peak intensity wavelength, allows determination of HIV infection, Hepatitis A, B and C, and other similar infection in the plasma. Selective absorbents, such as C-M Affi Gel Blue and activated charcoal, may be used to treat the samples before fluorescence measurements, which is found to improve discrimination of infected and uninfected samples. The present invention is capable of detecting HIV infection at the stage when it is still undetectable by conventional diagnosis methods.

A quantitative process for monitoring female fertility cycle wherein the process involves directing a laser beam, preferably generated by a diode laser, onto an area of a slide containing an air-dried sample of a female body fluid. The diffraction pattern resulting from the sample is detected by a two-dimensional photo diode array and analyzed by a microprocessor. If a ferning pattern exists, such pattern will generate a characteristic structure in the diffraction pattern which is then detected by the photo diode array. If no ferning occurs, the corresponding diffraction pattern will be structureless. The microprocessor is programmed with an algorithm to produce a quantitative index of ferning indicating quantitatively the ferning level. Preferably, a plurality of spots on the sample are measured to determine the ferning level at each spot, and the microprocessor then makes a final determination as to final ferning level on the basis of the test results of all of the spots. This significantly increases the reliability of the final test result, since a defect at one test spot or anomaly of one test result will not be fatal to the final result.
