Abstract: Methods, systems, and devices for auto-calibration of error detection signals are described. An error may be injected into a data signal obtained from a memory array. After injecting the error into the data signal, the data signal may be applied to an error detection circuit of the memory array, where the error detection circuit may output an error signal for the data signal. The error signal may be delayed relative to a control signal by a first amount. A timing signal that controls the propagation of the error signal may be obtained based on delaying the control signal by a second amount. Based on a comparison of the error signal and the timing signal, a third amount for delaying the control signal may be determined.

Abstract: The present disclosure relates to electric motors. The electric motor assembly may include a rotor mounted coaxially on a shaft. The rotor may include a center lamination stack mounted on a balance ring. The center lamination stack may have slots along the outer circumference which hold pole pieces attached to a plurality of magnets. The magnets may be situated between the pole pieces and the center lamination stack. The magnets may not be fully enclosed by the metal body of the rotor. The described components of the rotor may be encased in a wound fiber sleeve. The rotor is rotably mounted within a stator.

Abstract: Systems and methods for enhanced techniques for analyzing induction motors. An example method includes accessing circuit model information associated with an induction motor (IM), the circuit model information representing rotor bars of the IM as each including respective rotor segments. Rotor segment nominal currents associated with the rotor segments are determined, with the determination being based on performing finite element analysis (FEA) over a grid and use of a linearized circuit model. Rotor segment ripple currents associated with the rotor segments are determined, with the determination being based on performance of FEA to extract flux ripple samples over the grid, with the flux ripple samples being transformed into a time-varying rotor flux ripple signal, and with the rotor segment ripple currents being determined based on the time-varying rotor flux ripple signal. Losses associated with the IM are determined.

Abstract: The present invention provides a method, terminal and system for implementing a multimedia coloring ring back tone (MCRBT) service in IMS domain. This method comprises: after receiving a call from a caller, a core network setting up a connection with a MCRBT service system when the callee is called if determining that the callee subscribes the MCRBT service; said MCRBT service system triggering the MCRBT service, and sending an address of a MCRBT file set by said callee through said core network; and said caller downloading said MCRBT file from a media resource server of said MCRBT service system according to said address, and enjoying said MCRBT file from a calling terminal when a called terminal rings. The present invention can meet the requirement of the caller of enjoying the MCRBT file set by the callee when the caller calls the callee of IMS domain, and better services are provided.
