    摘要: Electronic circuits and methods are provided for use in hot-swappable circuit board applications. Circuitry detects an electrical ground connection and signals operation of a hot-swap controller. Detection of stable operating power causes a hierarchical startup of plural voltage regulators. Sensing stable output power from the last of the voltage regulators triggers the configuration of one or more programmable devices. Circuitry and other resources of a hot-swappable circuit board are protected against electrical transient-related damage by virtue of the present teachings.

    摘要: Speed capability of a rotary stepping motor of the harmonic drive type is markedly increased by providing a stiffer, i.e. harder to radially deflect, structure of its rotor. Elimination of magnetically permeable bridging material as heretofore employed is made possible also in an alternate construction. Basically, thickness of a flexrotor or flexspline wall is made greater than hitherto relative to its outside diameter to provide a stiffness insuring efficient operation at increased natural or resonant frequency. Higher capability of the thicker-stiffer flexspline to maintain its sinusoidal shape during operation results in less tooth wear and increased efficiency over a longer operating life. When concentric ring bridging is incorporated, its total wall-to-outside-diameter ratio thickness is advantageously substantially that of the novel flexrotor or flexspline itself to obtain higher step rates efficiently.
