摘要： A block copolymer consisting essentially of crystalline polymerized propylene segments joined to crystalline segments of polymerized .alpha.-mono-olefinic hydrocarbon other than propylene. These block copolymers have an inherent viscosity in Tetralin at 145.degree. C. of from about 0.4 to 2.4, a density of at least 0.85, a brittle point below 0.degree. C. and contain at least 80 percent, by weight, of polymerized propylene.

摘要： Systems and methods for digitally controlling sensors. In one embodiment, a digital controller for a capacitance diaphragm gauge is embedded in a digital signal processor (DSP). The controller receives digitized input from a sensor AFE via a variable gain module, a zero offset module and an analog-to-digital converter. The controller automatically calibrates the received input by adjusting the variable gain and zero offset modules. The controller also monitors and adjusts a heater assembly to maintain an appropriate temperature at the sensor. The controller utilizes a kernel module that allocates processing resources to the various tasks of a gauge controller module. The kernel module repetitively executes iterations of a loop, wherein in each iteration, all of a set of high priority tasks are performed and one of a set of lower priority tasks are performed. The controller module thereby provides sensor measurement output at precisely periodic intervals, while performing ancillary functions as well.
