  • Patent number: 8690579
    Abstract: The dental position tracking system includes a toothbrush (30) which has a system (20) for determining the orientation of the toothbrush in the mouth of a user relative to the earth, based on measured stored information. Information is stored in the toothbrush concerning target ranges of expected measured toothbrush orientations for each of a plurality of dental zones (22). A processor (24) compares the measured toothbrush orientation information with the target orientation ranges, following conversion of both the target orientation information and the measured toothbrush orientation information to the same coordinate system. The processor then determines which if any of the target ranges matches, within a selected tolerance thereof, with the toothbrush orientation information. Any difference between the target range and the measured toothbrush orientation information is then used to partially adjust the target information range, in order to compensate for a change of position of the user's head.

  • Patent number: 8535236
    Abstract: An apparatus for analyzing a sound signal is based on an ear model for deriving, for a number of inner hair cells, an estimate for a time-varying concentration of transmitter substance inside a cleft between an inner hair cell and an associated auditory nerve from the sound signal so that an estimated inner hair cell cleft contents map over time is obtained. This map is analyzed by means of a pitch analyzer to obtain a pitch line over time, the pitch line indicating a pitch of the sound signal for respective time instants. A rhythm analyzer is operative for analyzing envelopes of estimates for selected inner hair cells, the inner hair cells being selected in accordance with the pitch line, so that segmentation instants are obtained, wherein a segmentation instant indicates an end of the preceding note or a start of a succeeding note. Thus, a human-related and reliable sound signal analysis can be obtained.

    Abstract: According to a disclosed embodiment, an auscultatory training apparatus includes a database of pre-recorded physiological sounds stored on a computer for playing on a playback system. A user-friendly, graphical user interface software program is stored on the computer for use with a conventional computer mouse. The program allows a user to select one of the pre-recorded sounds for playback. In addition, the program is operable to generate an inverse model of the playback system in the form of a digital filter. If employed by the user, the inverse model processes the selected sound to cancel the distortions of the playback system so that the sound is accurately reproduced in the playback system. The program also permits the extraction of a specific sound component from a pre-recorded sound so that only the extracted sound component is audible during playback.

  • Patent number: 6872080
    Abstract: A portable, interactive electronic training device for prompting a trainee on the proper sequence of steps for performing CPR, using a defibrillator and performing CPR in conjunction with the use of a defibrillator. The device simulates the obtaining of direct information about a patient's condition, such as ECG data collected directly from the patient. The device receives information pertinent to the treatment of the patient indirectly through an operator of the device. The device prompts a trainee on the medically appropriate action such as a defibrillation shock in response to the indirect and direct information. Indirect information is obtained through information processing means that includes means for prompting the operator of the device and means for receiving the operator's responses thereto. Prompts may include both questions and instructions, and in one embodiment the information processing means obtains the assent of the operator before causing the defibrillation shock.

  • Patent number: 6220866
    Abstract: An electronic auscultation system and method for simulating sounds arising from human organs for use in an anatomical simulation device including a patient simulating mannequin torso, a plurality of electro-magnetic transmitters having antenna coils positioned in predetermined locations relative to said torso beneath the torso surface and each transmitter being connected to one or more computer sound cards which, upon activation, generate signals from prerecorded sound data which generates the appropriate sounds of human organs based on the transmitter location. The system utilizes a simulated stethoscope that includes a receiver and/or sensing triggering devices so that the stethoscope can determine particular areas on the torso to define the appropriate sound generated such that the system knows where the stethoscope is.
