SELF-STABILIZING SKATEBOARD

A self-stabilizing, one-wheeled electric skateboard may include improved features. In some examples, the vehicle includes a status indicator viewable through a slot formed in an upper surface of the board. In some examples, the vehicle includes a convertible carrying handle transitionable between stowed and deployed positions. In some examples, the vehicle includes an interchangeable fender and fender substitute that may be removably coupled to an upper surface of the board. In some examples, a motor controller of the vehicle may operate a field-oriented control (FOC) scheme configured to control the electric motor by manipulating a direct current aligned with a rotating rotor flux angle and a quadrature current defined at ninety degrees from the rotating rotor flux angle. In some examples, the motor controller may be configured to permit intuitive dismounting of the vehicle by tilting and/or moving the vehicle backward.

Micro rate of rotation sensor and method for operating a micro rate of rotation sensor

The present invention relates to a method for operating a rotation sensor for detecting a plurality of rates of rotation about orthogonal axes (x,y,z). The rotation sensor comprises a substrate, driving masses, X-Y sensor masses, and Z sensor masses. The driving masses are driven by drive elements to oscillate in the X-direction. The X-Y sensor masses are coupled to the driving masses, and driven to oscillate in the X-Y direction radially to a center. When a rate of rotation of the substrate occurs about the X-axis or the Y-axis, the X-Y sensor masses are jointly deflected about the Y-axis or X-axis. When a rate of rotation of the substrate occurs about the Z-axis, the X-Y sensor masses are rotated about the Z-axis, and the Z sensor masses are deflected substantially in the X-direction.
