Electrical Engineering, 1939
The horsepower rating of a motor carries a dual implication — first, torque ability; second, temperature rise. The two are frequently confused. In selecting motors for duty-cycle jobs the two concepts should be considered separately. The motor rating and type should be chosen to fit the torque requirements of the job.

Synchronous duty cycle correction circuit
2010 18th IEEE/IFIP International Conference on VLSI and System-on-Chip, 2010A duty cycle correction (DCC) circuit with deterministic clock insertion delay is presented. To neutralize the ambiguity of the DCC circuit insertion delay induced by the wide range of input clock duty cycle, a signal differentiating circuit at the input of the circuit is used which narrows the input duty cycle range to the circuit core.

Clock buffer with duty cycle corrector
Microelectronics Journal, 2010A clock buffer with duty cycle corrector circuit is presented. The proposed circuit can generate either 50% duty cycle or conserve the duty cycle as input clock. It corrects the input duty cycle of 10-90% for generated 50% duty cycle of output clock with error less than 0.9%.

Impact of Duty Cycling on Opportunistic Communication
IEEE Transactions on Mobile Computing, 2016A major challenge in mobile wireless devices for opportunistic networks is to decrease the energy consumption. The decrease should not come at a cost of reduced application throughput (i.e., goodput). This work evaluates the potential performance gains for mobile nodes that adopt duty cycling in an opportunistic context.

On the duty cycle of cyclotrons
Nuclear Instruments and Methods, 1962The poor (1–6%) duty cycle of present day cyclotrons is mainly due to: 1. r.f. extraction from the ion source; 2. r.f. defocusing caused by part of the r.f. phase; 3. loss of phase due to relativistic effects; 4. phase bunching at small radii; and 5. inefficient extractors. Possible methods of improvement are: 1. d.c. extraction from the ion source; 2.

Hierarchical Duty-Cycling of Wireless Sensors
2019 28th International Conference on Computer Communication and Networks (ICCCN), 2019Energy efficiency is critical in many IoT applications with sensors that deliver data over wireless communications. Duty-cycling has been a major method for reducing energy consumption. One popular duty-cycling is MAC duty-cycling where an MCU commands the periodic or adaptive turning on and off of an RF chip.

Adaptive duty cycling for energy harvesting systems
Proceedings of the 2006 international symposium on Low power electronics and design - ISLPED '06, 2006Harvesting energy from the environment is feasible in many applications to ameliorate the energy limitations in sensor networks. In this paper, we present an adaptive duty cycling algorithm that allows energy harvesting sensor nodes to autonomously adjust their duty cycle according to the energy availability in the environment.

Merging ultra-low duty cycle networks
2011 IEEE/IFIP 41st International Conference on Dependable Systems & Networks (DSN), 2011Energy is the scarcest resource in ad-hoc wireless networks, particularly in wireless sensor networks requiring a long lifetime. Intermittently switching the radio on and off is widely adopted as the most effective way to keep energy consumption low.

On the Measurement of Duty Cycle and Channel Occupancy Rate
IEEE Journal on Selected Areas in Communications, 2013Duty cycle (DC) and channel occupancy rate (COR) measurements are important to characterize the availability of white space for cognitive radio systems (CRSs). The COR is related to the real occupancy of channels considered by a CRS but despite its importance it has not yet been widely considered for spectrum use measurements. Spectrum use measurements
