Abstract: A stump grinder has a grinding arm that durably mounts a rotatable grinding wheel by securing the drive shaft of a motor to the grinding wheel such that a pair of bearings within the motor support one side of the grinding wheel and by supporting the other side of the grinding wheel with a stub shaft received within a third bearing. The grinding arm is laterally offset on the frame of the stump grinder to have a swing angle that is not symmetrical relative to the width of the frame, but with the swing angle starting at one side of the frame and then traversing across substantially the entire width of the frame to improve the ability of the operator to see the grinding wheel. A single joystick is movable in orthogonal directions corresponding to desired up and down and side-to-side pivoting motions of the grinding arm. The joystick includes a depressible trigger for starting and stopping the operation of the grinding wheel.

Abstract: Various embodiments provide systems, methods, devices, and instructions for protected data use in a third-party software application, where use can be enabled while maintaining protection of the protected data from the third party software application. In particular, various embodiments provide a software application architecture that permits a data party that owns or maintains protected data to support a software development ecosystem where a third-party can develop a third-party software application that uses the protected data while denying the third-party access to the protected data.

Abstract: A data transmission system includes a transmitter circuit. The transmitter circuit receives regular data bits and auxiliary data bits. The transmitter circuit encodes a first subset of the regular data bits to generate a first subset of encoded data comprising pairs of symbols that are used in quadrature amplitude modulation. The transmitter circuit encodes the auxiliary data bits and a second subset of the regular data bits to generate a second subset of the encoded data comprising at least one pair of symbols that are unused for encoding by the quadrature amplitude modulation. The transmitter circuit generates a modulated output signal that indicates the first and second subsets of the encoded data using pulse amplitude modulation.
