摘要： Angular accelerometers are described, as are systems employing such accelerometers. The angular accelerometers may include a proof mass and rotational acceleration detection beams directed toward the center of the proof mass. The angular accelerometers may include sensing capabilities for angular acceleration about three orthogonal axes. The sensing regions for angular acceleration about one of the three axes may be positioned radially closer to the center of the proof mass than the sensing regions for angular acceleration about the other two axes. The proof mass may be connected to the substrate though one or more anchors.

摘要： An acceleration vector is detected in a kept-still state of a measurement target portion such as thighs of a target person to which an inertial sensor is attached, and further, another acceleration vector is detected in a state in which the target person is allowed to carry out exercise such that a posture of the measurement target portion is caused to change in a direction around a Yb axis with a Yb-axis direction of the measurement target portion maintained in a direction that perpendicularly intersects a vertical direction, direction in a sensor coordinate system the Yb-axis direction of the measurement target portion corresponds to is identified on the basis of a cross product vector of the acceleration vector and another acceleration vector.

摘要： A physical quantity sensor includes a physical quantity detection circuit having a determination circuit that determines whether a value of a physical quantity signal continuously remains within a predetermined range in a predetermined period, determines that a physical quantity detection element is in a first state of normal operation when the value does not continuously remain, and determines that the physical quantity detection element is in a second state of abnormal operation when the value continuously remains, a control circuit that stores first information based on a determination result of the determination circuit is stored in a control circuit as a setting information and a communication section that outputs the setting information stored in from the control circuit to the outside when the determination result of the determination circuit indicates the second state.

摘要： In some examples, an unmanned aerial vehicle (UAV) may receive location information via the global navigation satellite system (GNSS) receiver and may receive acceleration information via an onboard accelerometer. The UAV may determine a first measurement of acceleration of the UAV in a navigation frame of reference based on information from the accelerometer prior to or during takeoff. In addition, the UAV may determine a second measurement of acceleration of the UAV in a world frame of reference based on the location information received via the GNSS receiver prior to or during takeoff. The UAV may determine a relative heading of the UAV based on the first and second acceleration measurements. The determined relative heading may be used for navigation of the UAV at least one of during or after takeoff of the UAV.

摘要： Microelectromechanical system (MEMS) inertial sensors exhibiting reduced parasitic capacitance are described. The reduction in the parasitic capacitance may be achieved by forming localized regions of thick dielectric material. These localized regions may be formed inside trenches. Formation of trenches enables an increase in the vertical separation between a sense capacitor and the substrate, thereby reducing the parasitic capacitance in this region. The stationary electrode of the sense capacitor may be placed between the proof mass and the trench. The trench may be filled with a dielectric material. Part of the trench may be filled with air, in some circumstances, thereby further reducing the parasitic capacitance. These MEMS inertial sensors may serve, among other types of inertial sensors, as accelerometers and/or gyroscopes. Fabrication of these trenches may involve lateral oxidation, whereby columns of semiconductor material are oxidized.
