Abstract: Disclosed is a system and method for wireless motion control. The system generally includes a centralized motion coordinator device and one or more motion stick devices that communicate with each other wirelessly. The centralized motion coordinator controls operation of the one or more motion stick devices by wirelessly transmitting basic commands to the one or more motion stick devices. In response, the motion stick devices process the received commands and generate trajectory information based, at least in part, on the commands received from the centralized motion coordinator device. The trajectory information is used to control operation of a motor for advancement of an actuator assembly associated with the one or more motion stick devices along a predetermined axis.

Abstract: Apparatus for electronically producing a torque dependent signal for a plural drive phase synchronous step motor, without the use of an accelerometer or other external feedback device, includes a circuit for detecting respective instantaneous terminal voltage signals for at least two phases of the motor; another circuit for detecting respective instantaneous phase current signals for said at least two phases; and a signal processing circuit for combining the detected signals to produce said torque dependent signal.
