    Abstract: An apparatus or method determines a content of the one or more elements of a solid matrix by scanning the solid matrix using a PXRF spectrometer and a color sensor, receiving a PXRF spectra from the PXRF spectrometer and a numerical color data from the color sensor, extracting a value for each of the one or more elements the PXRF spectra, determining the content of the one or more elements of the solid matrix using one or more processors and a predictive model that relates the value of each of the one or more elements and the numerical color data to the content of the one or more elements of the solid matrix, and providing the content of the one or more elements of the solid matrix to one or more input/output interfaces.

    Abstract: An optical waveguide includes a first waveguide core, a second waveguide core, a first subwavelength multilayer cladding, a second subwavelength multilayer cladding and a third subwavelength multilayer cladding. The first waveguide core and the second waveguide core have a width (w) and a height ( h ). The first waveguide core is disposed between the first subwavelength multilayer cladding and the second subwavelength multilayer cladding. The second waveguide core is disposed between the second subwavelength multilayer cladding and the third subwavelength multilayer cladding. Each subwavelength multilayer cladding has a number (TV) of alternating subwavelength ridges having a periodicy (A) and a filling fraction (p). A total coupling coefficient (|/c|) of the first waveguide core and the second waveguide core is from 10 to 0.

    Abstract: The invention presents a hand held guide for cue shaft with an adjustable handle for playing billiard games. The guide comprises an elongated "V"-shaped guide containing said adjustable handle at least one axis that allow the pieces forming the axis to articulate up to 180 degrees. In addition, the handle contains at least one adjustable grip and the elongated "V"-shaped guide contains at least one concave groove to place the index finger or the middle finger when the person using the guide performs a closed bridge to wrap the guide.

    Abstract: A behavioral state of a brain is classified by automatically selecting one or more sensors based on the signals received from each sensor and one or more selection criteria using one or more processors, calculating at least one measured value from the signal(s) of the selected sensor(s), classifying the behavioral state as: (a) an awake state whenever the measured value(s) for the selected sensor(s) is lower than a first threshold value, (b) a sleep state (N2) whenever the measured value(s) for the selected sensor(s) is equal to or greater than the first threshold value and the measured value(s) is not greater than a second threshold value, or (c) a slow wave sleep state (N3) whenever the measured value(s) from the selected sensor(s) is greater than the first threshold value and the measured value(s) is greater than the second threshold value, and providing a notification of the classified behavioral state.

    Abstract: The present invention includes a method of making a RF impedance matching device in a photo definable glass ceramic substrate. A ground plane may be used to adjacent to or below the RF Transmission Line in order to prevent parasitic electronic signals, RF signals, differential voltage build up and floating grounds from disrupting and degrading the performance of isolated electronic devices by the fabrication of electrical isolation and ground plane structures on a photo-definable glass substrate.
