    Patent
    The University of Auckland Library

    A tooth treatment device includes a detector that detects a marker of oral health and a fluid ejector that ejects fluid against teeth in response to the detected marker. The device can include a housing configured to be held on hand, the fluid ejector being positioned at an end of the housing. The fluid may include a liquid, a medicant, a cleansing solution, cleaning particles, or any combination thereof. The medicant can include any combination of a chelating agent, fluoride, a fluorescent dye, a bacterial specific probe, and a biochemical specific biomarker. Further, the device can include a servo controller controlling pressure of ejected fluid in response to the detected marker and a sensed surface condition, latter including for example, a mechanical property of tissue. The device may include a pressure sensor that senses pressure of the fluid in the ejector. Also included may be a distance sensor that senses distance of the ejector from a tissue surface. The surface condition may be sensed using the sensed pressure, sensed distance, or any combination thereof. In some embodiments, the fluid ejector comprises a stationary magnet assembly providing a magnetic field and a coil assembly, slidably disposed with respect to the magnet assembly, the coil assembly driving ejection of the fluid jet. A method of tooth treatment includes detecting a marker of oral health and controlling ejection of a fluid jet against the tooth responsive to the detected marker. In some embodiments, detecting the marker includes detecting plaque and the ejection is controlled to clean the plaque. Detecting the marker can include collecting a sample from an oral cavity.

  • System and method for tracking facial muscle and eye motion for computer graphics animation

    Sagar, Mark; Scott, R (2009)

    Patent
    The University of Auckland Library

    A motion tracking system enables faithful capture of subtle facial and eye motion using a surface electromyography (EMG) detection method to detect muscle movements and an electrooculogram (EOG) detection method to detect eye movements. An embodiment of the motion tracking animation system comprises a plurality of pairs of EOG electrodes adapted to be affixed to the skin surface of the performer at locations adjacent to the performer's eyes. The EOG data comprises electrical signals corresponding to eye movements of a performer during a performance. Programming instructions further provide processing of the EOG data and mapping of processed EOG data onto an animated character. As a result, the animated character will exhibit he same muscle and eye movements as the performer.

  • Dielectric elastomer self-sensing using plane approximation

    O'Brien, BM; Gisby, TA; Anderson, IA (2011)

    Patent
    The University of Auckland Library

    The present invention provides a method for obtaining feedback parameters related to the state of a dielectric elastomer (DE). The method comprises introducing a small-scale oscillation to the voltage difference between electrodes of the DE, monitoring or repeatedly measuring several measurable electrical characteristics of the DE, deriving other relevant data from the measurements, deriving an equation for a plane of best fit through the relevant data when defined as orthogonal axes, and deriving the feedback parameters from coefficients of the plane equation. The method thus provides important feedback regarding the capacitance, leakage current and/or electrode resistance of the DE. Also disclosed are a computer program and a system adapted to perform the method.

  • 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..
