    摘要： A linear motion control device for use in a linear control system is presented. The linear motion control device includes a coil driver to drive a coil that, when driven, effects a linear movement by a motion device having a magnet. The linear motion control device also includes a magnetic field sensor to detect a magnetic field associated with the linear movement and an interface to connect an output of the magnetic field sensor and an input of the coil driver to an external controller. The interface includes a feedback loop to relate the magnetic field sensor output signal to the coil driver input.

    摘要： A magnetic field sensor for low power applications includes a magnetic field sensing element that, during sample intervals, provides a signal proportional to a sensed magnetic field and also includes a comparator circuit that, during the sample intervals, compares the magnetic field signal to threshold levels to generate a sensor output signal indicative of a strength of the magnetic field. According to a dual sample rate feature, initially the magnetic field signal is sampled at a first predetermined sample rate and, following detection of a transition of the sensor output signal, is sampled at a second, faster predetermined sample rate for a predetermined interval. According to a user-programmable sample rate feature, a user may select to operate the sensor at a fixed, predetermined sample rate or at a user-specified sample rate. The magnetic field sensor may also or alternatively detect the speed and/or direction of rotation of a rotating magnetic article.

    摘要： Processes are described for epoxidation reactions. In particular, the process comprises the conversion of a steroid substrate having an olefinic unsaturation in the steroid nucleus to a structure comprising a 9,11-epoxy substituent by reaction of the substrate with a peroxide compound in the presence of a peroxide activator. The epoxidation processes described are conducted at relatively low hydrogen peroxide to steroid substrate ratio. Several optional process modifications are described.
