An intelligent electronic device has enhanced power quality and communications capabilities. The patient effort is commonly measured via work of breathing, power of breathing, or pressure-time product of esophageal pressure and is important for properly adjusting ventilatory support for spontaneously breathing patients. 0 wt %, based on the total weight of the curable adhesive composition, and copper powder in a range of 0. , a telomere damage-inducing agent such as paclitaxel, and a telomerase inhibitory agent such as AZT. The invention may include different user interfaces. In one implementation, a system includes an image data source for providing image pixel data, an image filtering coefficient source for providing a plurality of image filtering coefficient sets, and image processing logic capable of at least filtering the image pixel data using one or more image filtering coefficient sets specified by one or more indicators.
