)A device that draws pictures on paper based on commands from a computer. Plotters differ from printers in that they draw lines using a pen. As a result, they can produce continuous lines, whereas printers can only simulate lines by printing a closely spaced series of dots. Multicolor plotters use different-colored pens to draw different colors. In general, plotters are considerably more expensive than printers.
A hiccup (/ËhÉªkÉpËËhÉªkÊp/ HIK-Ép, HIK-up; also spelled hiccough) is an involuntary contraction (myoclonic jerk) of the diaphragm that may repeat several times per minute. In medicine, it is known as synchronous diaphragmatic flutter (SDF), or singultus, Latin for the act of catching one's breath while sobbing.
Some experts think that hiccups in utero is a response to fetal drinking or fetal breathing, which causes the flow of amniotic fluid in and out of the lungs, stimulating the diaphragm to contract. Hiccups in unborn babies do not seem to cause the same discomfort as it does in adults.iccups for an unborn baby are completely normal. When your baby hiccups, it will feel like a small spasm in your belly. Hiccups will generally feel distinct from other sorts of movements. Some babies will not hiccup at all while still in the womb, while others may hiccup several times a day every day.
