Abstract: A method of controlling an operation of a mechanical transmission system includes receiving motor-load data corresponding to the mechanical transmission system. The method further includes receiving, by a digital motor unit, one or more motor input parameters and generating motor parameter estimates of one or more of the plurality of motor parameters. The method also includes receiving, by a digital load unit, one or more motor parameter estimates from the digital motor unit and generating load parameter estimates corresponding to one or more load parameters. The digital motor unit and the digital load unit is a real-time operational model of the motor unit and the load unit respectively. The method also includes controlling the operation of the mechanical transmission system based on one or more of the motor-load data, motor parameter estimates and load parameter estimates.

Abstract: A system includes a light emitting unit, a front mirror, a rear mirror, an imaging unit and a processor. The light emitting unit is configured to emit a collimated light beam. The front mirror is configured to reflect part of the collimated light beam to produce and project a front focused ring of structured light to an object to obtain a front reflected ring of light, and configured to allow part of the collimated light beam to pass by. The rear mirror is positioned downstream of a light transmitting path of the front mirror. The rear mirror is configured to reflect at least part of the collimated light beam passing by the front mirror to produce and project a rear focused ring of the structured light to the object to obtain a rear reflected ring of light.

Abstract: A system may include a motor that has a rotor and a stator. The system may include one or more sensors that measure a voltage signal of a winding of the stator. The system may include a processor that executes computer-executable instructions which, when executed, cause the processor to receive, from the one or more sensors, the voltage signal that includes an induced voltage signal associated with the winding of the stator, to determine a time constant associated with the induced voltage signal based on a decay pattern of the induced voltage signal, to determine a temperature of a rotor based on the time constant, and to adjust one or more operations of the motor based on the temperature.
