Active mode This is the power of the device when in operation. 

The PWR DN command activates the power-down mode. In this mode, aU the analog blocks are switched-off reducing the power consumption from 20 mA (aU blocks of the chip are active, microhotplate at 300 °C) to 2 mA (only digital blocks are active). 

Another striking difference between normal and cultured skin is shown in Fig. 15.6. As discussed above (see Fig. 15.3c, factor 2), cholesterol-rich pockets containing highly ordered lipid chains are occasionally detected in human skin and are characterized by a Raman-active mode of cholesterol near 700 cm-1 and an intense lipid C-C stretch near 1130 cm-1 in Fig. 15.4a and b, respectively. The intensity of the cholesterol mode is normalized to a Phe vibration near 620 cm-1 and imaged in Fig. 15.6b. As is evident there are many such pockets in the cultured skin model, in contrast to human skin where they are only rarely observed (Fig. 15.3c, factor 2), and usually in the viable epidermis rather than in the SC (as in the cultured skin). These measurements illustrate the power of confocal Raman microscopy for combining spatial measurements with molecular structure characterization. 

The tasks cannot be pre-empted. Each task is characterized by its execution time and deadline. The execution time is measured in number of clock cycles, NC. Assume that the processor has two modes an active mode and a power saving mode [Kar 99]. The task deadline Tdl accommodates both the active period Tact and the power-saving period Tps... 

The acquisition of solid-state C-NMR spectra at various temperatures can be a powerful approach to the study of molecular motion in solids and for the study of phase conversion. Such methodology was used to study the two polymorphs of 2,2-bis( -acetoxyphenyl)propane, where markedly different molecular mobilities were found to exist in the two crystal structures [155]. Below the glass transition temperature, the important active mode correlates with the flipping of the phenylene rings, and this effect was evident in the NMR spectra obtained at different temperatures. Some of the resonance bands associated with Form II were found to coalesce upon sample heating from -10° C to ambient probe temperature.

An interesting feature of the Z-source DC circuit breaker is its ability to automatically respond to a short-circuit fault in its DC load and to protect the power source from the fault. A Z-source circuit breaker between a power source and an inverter (Fig. 8.47) allows to simultaneously close the upper and the lower power switch of an inverter phase leg. The combination of a Z-source circuit and an inverter is known as Z-source inverter (ZSI). If both switches of a phase leg are on, the inverter is said to be in shoot-through mode. That is, the Z-source inverter has another mode in addition to the six active modes and the two null modes of a traditional 3-phase inverter.
