duty cycle

the percentage of time that ultrasound is being generated (pulse duration) over one pulse period. Also called duty factor, mark:space ratio.

du·ty cy·cle

(ti:ttot) (dū'tē sī'kĕl)
The ratio of inspiratory (ti) time to total-breathing-cycle time (ttot).

duty cycle

During chest compressions of a victim of cardiac arrest, the relative amount of time that the chest is compressed compared to the time that the chest is allowed to recoil to its fully inflated position. A cycle of 50% occurs when chest compression equals chest recoil.

In terms of the duty cycle, meanwhile, the average current increases in proportion to the duty cycle, but the dither amplitude is maximized at 50% duty cycle and becomes zero at 0% and 100% duty cycles.
It is certainly value added since it would be closer the real world duty cycles, and therefore easier to conduct truly comparative performance scenarios for different systems.
The correct equivalent DC current for each duty cycle is the effective RMS current (for a square wave), given by the formula RMS = 5 * SQRT (DCy), where DCy is the duty cycle expressed as a fraction.
The algorithm requires the knowledge of the location of the PV panel operation point and the controller is switching between adaptive duty cycle control and fixed duty cycle control.
Different simulations are performed with both converters at various duty cycles.
The result is a DPF with an extended application range for highway and nonroad diesel engines with an enhanced ability to operate under variable or colder duty cycles, the company said.
The Waveforms for different duty cycles at the output of buffer after implementation are shown in figure 4 and the output waveforms with load for different duty cycles are shown in figure 5.
S6 -- Continuous operation--periodic duty type: A sequence of similar duty cycles at constant load separated by no-load--but continuously running--condition.
As a result, the net change to the combined duty cycles for all stages always equals zero.
Little can be done to control these temperatures, Winkle admits, but it's for this reason that the company recommends purchasing magnets designed for hot surface work and proper duty cycles.
However, in this new era of SAN-based backup, automated tape libraries and the underlying tape drive technology are facing the challenge of dramatically higher duty cycles and rigid uptime and availability requirements.
Kluemper and his crew arrived with Spectrum Expert and saw duty cycles in the 70s with peaks of 100.
