摘要： An X-axis acceleration level determining section determines whether an X-axis acceleration signal output from a three-axis acceleration sensor has a value equal to or more than a predetermined positive threshold level, a value equal to or less than a predetermined negative threshold level, a value between the positive threshold level and a level of 0, or a value between the level of 0 and the negative threshold level. A Y-axis acceleration level determining section also makes a similar determination for a Y-axis acceleration signal output from the three-axis acceleration sensor. An attitude determining section determines the rotated attitude of a device equipped with the three-axis acceleration sensor with respect to the Z axis based on results of determinations made by the X-axis acceleration level determining section and the Y-axis acceleration level determining section.

摘要： A method for measuring positional changes of an object, including rotation about any or all of three axes, using linear accelerometers. There is disclosed a method of using a linear accelerometer to integrate two other 3D linear accelerometers in order to measure and supply for further use six-dimensional information, that is, translation in three dimensions and rotation about three axes. Two linear accelerometer sensors are used to determine all but one of the variables in the six degrees of freedom. Output from a third accelerometer generates the data need to determine a sixth, rotational, degree of freedom. The need for a gyroscope for detecting changes in heading (i.e., yaw or azimuth) may therefore be avoided.

摘要： A system includes a support, a pendular element, an elastic restraint, an image sensor, and a processing system. The elastic restraint couples the pendular element to the support and applies to the pendular element a restraining force that opposes movement of the pendular element in at least a first direction. The image sensor captures images of the pendular element. The processing system determines one or more movement measures describing movement of the support from comparisons of ones of the images captured by the image sensor. In another aspect, a pendular element is elastically coupled to a support. A restraining force that opposes movement of the pendular element in at least a first direction is applied to the pendular element. Images of the pendular element are captured. One or more movement measures describing movement of the support are determined from comparisons of ones of the captured images.

摘要： A five degree of freedom inertial measurement unit capable of measuring: linear acceleration of a body along a first axis, a second axis, and a third axis; angular acceleration of the body about the second axis; and angular acceleration of the body about the third axis. The first axis, the second axis, and third axis are substantially mutually orthogonal and intersect at an origin point. The unit includes first and second accelerometers that are in fixed positions relative to the body. The first accelerometer measures linear acceleration along both the second axis and the third axis. The second accelerometer measures linear acceleration along both the second axis and third axis. The first and second accelerometers are positioned on a plane defined by the first axis and the second axis. A controller is operatively coupled to the first accelerometer and the second accelerometer. The controller determines the angular acceleration of the body about the second axis, and the angular acceleration of the body about the third axis. The controller determines angular acceleration using no other acceleration signals other than the linear acceleration signals from the first and second accelerometers.

The angular speed sensor includes an oscillator capable of oscillating by a driving force and displaceable in accordance with a Coriolis force attributed to an angular speed of the oscillator. The acceleration sensor includes a movable portion displaceable in accordance with an acceleration applied to the acceleration sensor. The oscillator has a driving direction, which is not parallel to a displacement direction of the movable portion. The physical quantity sensor having the angular speed sensor and the acceleration sensor detects both of the angular speed and the acceleration with high accuracy.

摘要： An inertial measurement unit is provided in which an arrangement of linear accelerometers in fixed positions measure angular acceleration and other inertial characteristics. Only linear acceleration readings are required for measurement of angular acceleration, and both expensive angular sensors and cyclically driven linear accelerometers are eliminated. A processor receives the linear accelerometer signals and calculates output values related to both the angular and linear motion of the body. In the preferred embodiment, the inertial measurement unit includes at least nine linear accelerometers, three disposed with their respective sensitive axes in substantially mutually orthogonal relationship defining first, second and third axes intersecting at a single origin point, and a pair of linear accelerometers disposed along each axis spaced at fixed distances from the origin point with their sensitive axes in substantially orthogonal relationship with each other and the axis. The present invention also includes a control system using the inertial measurement unit of the present invention to control the operation of a first component in response to angular motion of a second component connected thereto, and a method for inertial measurement of angular acceleration.
