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.

A count (ON period time) is loaded onto one of the General Purpose Registers (GPR) which is also the Duty Cycle Register.
SDLT media also incorporates a new lubricant that supports the higher duty cycles demand by reducing friction between the tape and the read/write heads, leading to extended head and tape life.
The measurements include a spectral analysis of jitter components, along with a direct measure of duty cycle dependent jitter.

The unit provides a 250-amp DC output at 100% duty cycle for stick and TIG welding and a 275-amp CV output at a 60% duty cycle for MIG and flux-cored Innershield[R] welding.
Designed for high duty cycle applications, the POS has a much lower sensitivity to outside influences, which allows the Super DLTtape system to achieve a track count with an order of magnitude increase over current DLTtape products.
