摘要： A system and method for determining the position and orientation of a wearable audio device, for example, methods and systems for determining the position, orientation, and/or height of a wearable audio device using acoustic beacons. In some examples, the determined position, orientation, and/or height can be utilized to correct for drift experienced by an inertial measurement unit (IMU). In other examples, the drift may cause am externalized or virtualize audio source, generated within a known environment, to move or drift relative to the known locations of physical audio sources within the environment. Thus, the systems and methods described herein can be utilized to correct for drift in the position of a virtual audio source with respect to the wearable audio device by first determining its own absolute position and orientation within the environment.

摘要： In some examples, an unmanned aerial vehicle (UAV) may determine a first acceleration of the UAV based at least on information from an onboard accelerometer received at least one of prior to or during takeoff. The UAV may determine a second acceleration of the UAV based at least on location information received via a satellite positioning system receiver at least one of prior to or during takeoff. The UAV may further determine a relative heading of the UAV based at least in part on the first acceleration and the second acceleration, and may be directed to navigate an environment based at least on the determined relative heading.

摘要： A system for checking an inertial measurement unit of a vehicle, in particular a land vehicle, during driving includes the inertial measurement unit having: a first acceleration sensor configured to measure a translational acceleration along a first sensor axis and/or a first rate-of-rotation sensor configured to measure a rate of rotation about the first sensor axis and also a second acceleration sensor configured to measure a translational acceleration along a second sensor axis and/or a second rate-of-rotation sensor configured to measure a rate of rotation about the second sensor axis. A sensing device senses a movement of the vehicle in a first vehicle direction and/or about the first vehicle direction. Both the first sensor axis and the second sensor axis are tilted with respect to the first vehicle direction.

摘要： A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.
