    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: There is described a method for determining a value of a zero point offset of a yaw rate sensor. The method comprises measuring over time the output of the yaw rate sensor, determining whether the measured output has remained within a set of limits for a pre-determined period and if it is determined that the measured output has remained within the limits for the pre-determined period, using at least one measured value of the output to determine the value of the zero point offset.

    摘要: The preferred embodiments of the present invention are directed to methods and systems for dynamic route estimation and prediction using discrete sampled location updates from various mobile devices for the purpose of providing a graphical representation of a mobile device's route along a known network path of map data. The embodiments also provide supplemental route metrics, such as traveled distance, elapsed time, etc., and the capability to assign destination points for the purpose of providing the ability to modify location update points in an application, such as a route planner, and/or to store the dynamically generated route based on various preferences for later retrieval.

    摘要: A control module for a walk behind trowel configured to detect and to prevent an uncontrolled or undesirable motion of the trowel. The trowel includes an engine configured to drive rotation of a rotor. The control module includes a gyroscope and a controller. The gyroscope is configured to provide an electrical signal representative of an angular rate of motion of a reference structure on the walk behind trowel. The controller is configured to receive the electrical signal from the gyroscope and to determine when a change in the angular rate of motion of the trowel exceeds a threshold value, and in response, to prevent the engine from driving the rotor to rotate.
