    摘要： A system to detect a man down situation using intra-aural inertial measurement units is disclosed. The system comprises an earpiece having an inertial measurement unit (IMU) adapted to capture acceleration and rotation speed of the earpiece. The method comprises a training phase to characterize statistical distribution models of extreme values of feature signals, segmented by their respective optimally-sized time windows and to merge the detection probability provided by the statistical model of the feature signals. The method further comprises a prediction phase. The prediction phase comprises applying the detection strategy on independent data, based on the critical states obtained from the characterization. The data from the said inertial measurement of the MEMS are used for the detection of full (F), immobility (I) and down on the ground (D) states.

    摘要： Systems and methods related to gyroscope related applications. A platform having at least one torus shaped channel that is filled with a liquid is used in conjunction with at least one marker to determine the direction of forces applied to the platform. Each marker is neutrally buoyant within the liquid and a marker tracking system is used to determine the displacement of the marker from its resting place after a force has been applied to the platform. The tracking system may be based on at least one digital camera in conjunction with suitable image processing software to determine the marker's position before, during, and after the force has been applied. A gyroscope can be constructed using three such platforms with each platform being orthogonal to the other two. Each platform may have multiple concentric channels with a common center with each channel having a different sensitivity to the applied forces.

    摘要： A three-axis accelerometer includes a single, integrated mass including at least one lateral (x-y) proof mass and at least one vertical (z) proof mass. The vertical proof mass is arranged as a teeter-totter mass, which is located within the lateral proof mass. The vertical proof mass is mechanically coupled to the lateral proof mass with one or more torsional springs, and the lateral proof mass is mechanically coupled to one or more anchors with one or more lateral springs. The at least one vertical proof mass may be symmetrically positioned about one or more axes of the three-axis accelerometer, so that the 3-axis accelerometer has in-plane symmetry. The three-axis accelerometer may be less susceptible for mechanical cross-talk or noise and may provide a smaller packaged solution for sensing acceleration in three directions.
