摘要： A circuit, system and method adjusts a reference voltage, such as an internal or external reference voltage VREF, in response to a first voltage at a first contact, such as a pin on a memory controller used for reading or writing data, and a second voltage at a second contact in embodiments. Logic is coupled to the first and second contacts to provide a control signal in response to the first and second voltages. A comparator provides an input signal to the logic in response to a target reference voltage and the reference voltage during a calibration or initialization mode of operation. In an alternate embodiment, a plurality of data values at a first contact are compared to a predetermined plurality of test data. An up/down signal is then provided to a counter and a register stores a counter value used to provide a reference voltage.

摘要： A clutch assembly that includes an input member rotatable about an axis, an output member rotatable about the axis, and an engagement member having a portion between the input and output members. The engagement member is operable to selectively couple the input and output members together for co-rotation. The clutch assembly further includes a blocking member having a base and a projection. The projection is coupled to the engagement member to substantially prevent the engagement member from coupling the input and output members together for co-rotation when the input member rotates in a first direction relative to the output member, while allowing the engagement member to couple the input and output members lor together co-rotation when the input member rotates in a second direction relative to the output member.

摘要： A current control circuit that employs a magnetic amplifier and an active feedback circuit. The feedback circuit establishes the effective operating current of the amplifier at a fixed point. The magnetic amplifier includes a pair of oppositely wound gate windings, a bias winding and a control winding. The gate windings are driven by an oscillator driver that generates a gate winding current and a gate winding voltage. A reference voltage and the gate winding voltage are applied to a feedback amplifier and the feedback circuit. When the gate winding voltage becomes equal to the reference voltage, the feedback circuit is stable and the gate winding current is set to a desired zero current operating point.
