thread_title:  Duty ratio in locomotion ?

message: For no apparent reason (which math hounds prolly understand) the example period changed from minutes to seconds.  At first glance it appears to claim that an arc welder with 20% duty cycle must run two seconds on, then 8 seconds off.   quote:
::In equipment such as a welding power supply, the maximum duty cycle is defined as the percentage of time in a 10 minute period that it can be operated continuously before overheating.[6] ............ snip........Based on this analysis the signal is 1 V for 0<t<2 and 0 V for 2<t<10, therefore the period is T= 10 seconds, and the duty cycle is then ON/Period of the signal i.e., 2/10 = 0.2, which gives a duty cycle of 20%
Wasn't period already industry-standardized at 10 minutes? So why the swap? (I'm not questioning the arithmetic, just the communication device.) Why any mathy stuff at all here? 
I'm removing this, perhaps it can be made more realistic? <BR>
::For example, let's say a DC signal of 1 volt  starts at time t=0 seconds, and stays there for t=2 seconds, at which point the DC signal goes to 0 volts and stays there until t=10 seconds. At time t = 10 the signal goes back to 1 volt, and the process repeats over and over again. Based on this analysis the signal is 1 V for 0<t<2 and 0 V for 2<t<10, therefore the period is T= 10 seconds, and the duty cycle is then ON/Period of the signal i.e., 2/10 = 0.2, which gives a duty cycle of 20%

message: Although the term, "duty cycle," has its origins in engineering, it is also used by many physiologists to analyze biological data such as muscle contraction and bursting by neurons. Therefore, I would like to propose broadening the scope of this article to include living systems, a section on biological data, and to omit "in engineering" at the beginning of the first sentence. Comments welcome. danielkueh (talk) 16:58, 16 December 2011 (UTC)
replies: text: Seems fair, though really it applies to any mechanical (inc. acoustic, thermal...) or electric (inc nervous, photonic...) system that can be modelled, particularly in terms of energy flow and accumulating stress factors (waste heat, combustion/respiration products, etc). It's a fairly universal idea. OTOH what you describe could be called BioEngineering :) 51.7.16.140 (talk) 13:26, 28 August 2016 (UTC)

message: The term "square wave" is used in a couple different places in the article to refer to what I'm sure would be more correctly termed a Rectangular Wave or Pulse Wave (depending on whether the "off" state is taken as -1 or 0, vs "on" being +1). A square wave being a rectangle or pulse with a duty cycle of 50%. Any variation from that, and, well, the wave isn't "square" any more (with a typical scaling that has a square scope and the amplitude and wavelength both normalised to fill the screen, and the wave being Pulse, ie off is 0 rather than -1, when on is 1), but two unequal rectangles. It also has a particular tone which, as demonstrated by the varying pulsewidth animation, is discernable from other duty cycles simply by ear. 51.7.16.140 (talk) 13:31, 28 August 2016 (UTC)
