  • Cascaded Raman Laser

    Martinelli, C; Leplingard, F; Sylvestre, T; Vanholsbeeck, Frederique; Emplit, P (2006-02-07)

    Patent
    The University of Auckland Library

    A cascaded Raman laser (10) has a pump radiation source (12) emitting at a pump wavelength λp, an input section (14) and an output section (16) made of an optical medium. Each section (14, 16) comprises wavelength selectors (141, 142, . . . , 145 and 161, 162, . . . , 165) for wavelengths λ1, λ2, . . . , λn−k, where n≧3, λp< . . . <λn and λn−k+1, λn−k+2, . . . , λn being k≧1 emitting wavelengths of the laser (10). The laser further comprises an intracavity section (18) that is made of a non-linear optical medium, has a zero-dispersion wavelength λ0 and is disposed between the input (14) and the output (16) section. The wavelengths λ1, λ2, . . . , λn−k of the wavelength selectors (141, 142, . . . , 145 and 161, 162, . . . , 165) and the zero-dispersion wavelength λ0 of the intracavity section (18) are chosen such that energy is transferred between different wavelengths by multi-wave mixing.

  • Diagnostically and audibly responsive computer learning memory game and system provided therefor

    Dowrick, Peter (2006)

    Patent
    The University of Auckland Library

    A diagnostically and audibly responsive computer learning memory game works with small children and other persons in teaching them to read. Square or rectangular tiles to be uncovered are displayed upside down, concealing words to be matched with words or words to be matched with phrases or visual pictures or audible sounds, objective is to find matching cards. The computer game matches the cards or tiles with sight words that the user is learning to read from a word list. The user must remember where a correct word of the word pairs is located. The user must read word orally, if not, the computer will prompt the user with a clue (such as the beginning sound of a word) until the user answers. If nothing is heard, the user is told the answer. The system has a built-in recording of a library of selected words, phrases, pictures or audible sounds. The computer can sense that user is silent (with a default of no sound). If a wrong word is uttered, the system can remain silent or correct..

  • Method and system of measuring charateristics of an organ

    Young, Alistair; Cowan, Brett (2006-12-26)

    Patent
    The University of Auckland Library

    The invention provides a method of measuring characteristics of an organ or part thereof from multiple images of the organ or part thereof, the method comprising the steps of defining the spatial position of at least two of the images; defining a reference model of the organ or part thereof scaled according to the distance between reference markers on the images; defining one or more boundary guide points associated with one or more images for which the spatial positions have been defined; converting the guide points to three-dimensional coordinates; defining an estimate model by fitting the reference model to the guide points; and calculating the characteristics from the estimate model. The invention also provides a system and a computer program for measuring characteristics of an organ or part thereof of a subject from multiple images of the subject's organ or part thereof.
