    Abstract: Embodiments are directed to a stepper motor and a controller, where the controller measures a parameter associated with a current of the stepper motor prior to support of commanding a step in connection with the stepper motor. That is, the controller commands the step in connection with the stepper motor, measures a parameter subsequent to commanding the step, compares the measurements of the parameter, and determines whether a fault exists with respect to the stepper motor based on the comparison of the measurements.

    Abstract: A resolver interface includes an excitation coil, a first secondary coil, a second secondary coil, a sampling circuit, and a controller. The excitation coil receives an excitation signal that generates first and second signals in the first secondary coil and the second secondary coil, respectively. The sampling circuit includes a multiplexer that samples at least one period of the excitation signal, the first signal, and the second signal, individually. The controller is configured to calculate a sign of the first signal and the second signal relative to the excitation signal, wherein based on the calculated sign of the first signal and the second signal the controller determines a quadrant of the excitation coil and based on the determined quadrant and magnitudes of the sampled first signal and second signal calculates a position of the excitation coil.

    Abstract: Embodiments are directed to commanding, by a controller, a step in connection with a stepper motor, discharging a current in a coil of the stepper motor by transferring the current to a capacitor coupled to the coil responsive to the commanded step, and driving a current in the coil by using charge stored on the capacitor during the discharging of the current in the coil.

    Abstract: An integrated TDM-based/packet-based telecommunications backplane system includes a multi-bit backplane bus, a plurality of TDM data modules and packet based data modules coupled to the backplane bus, and a frame controller coupled to the bus which generates a frame by pre-assigning a first plurality of timeslots of a frame for the fixed rate TDM traffic, and allotting the remainder of the frame timeslots as a pool for packet-based traffic. The TDM data modules, which can include bit, and byte or nibble mode modules, place data on the backplane bus in their allotted time slots. The packet-based data modules contend for the pooled timeslots by raising a request on a "request" thread of the backplane bus when the packet module has a packet to send, and dropping the request and raising a busy flag on the "busy" thread while sending a data packet. In order to insure that only one packet-based data module will attempt to raise the request flag at a given time, the pooled timeslots are divided among the packet data sources for purposes of raising the request flag only. Thus, only one packet-based data module can raise its request flag during a given timeslot of the pool; although when sending data, the packet-based data module can send during all timeslots of the pool.

    Abstract translation: 集成的基于TDM的/基于分组的电信背板系统包括耦合到背板总线的多位背板总线，多个TDM数据模块和基于分组的数据模块，以及耦合到总线的帧控制器，其通过 为固定速率TDM业务预分配帧的第一多个时隙，以及将所述帧时隙的剩余部分分配为用于基于分组的业务的池。 可以包括位和字节或半字节模式的TDM数据模块在其分配的时隙中将数据放置在背板总线上。 基于分组的数据模块通过在分组模块具有要发送的分组的情况下通过背板总线的“请求”线程提出请求来竞争合并的时隙，并且在“忙”线程上丢弃请求并提出忙标志 同时发送数据包。 为了确保在给定时间只有一个基于分组的数据模块将尝试提出请求标志，为了提高请求标志的目的，合并的时隙在分组数据源之间被划分。 因此，只有一个基于分组的数据模块可以在池的给定时隙中提出其请求标志; 虽然发送数据时，基于数据包的数据模块可以在池的所有时隙中发送。
