Cov qib hluav taws xob muaj xws li tus kav lub cev thiab qib npuas. Ob sab ntawm txhua qhov kawg ntawm cov npuas theem yog feem ntau muab nrog ib qho infrared emitting raj thiab ib lub raj txais infrared uas txuas nrog lub hwj huam mov thiab sib haum rau cov haujlwm. txuas nrog hluav taws xob Circuit Court. Thaum lub sij hawm ntsuas, thaum lub npuas txav mus rau sab laug lossis sab xis, lub teeb ci ntawm lub raj tau txais infrared ntawm qhov sib txuas qhov kawg hloov, kom cov zis kawg ua rau qis qis, thiab txoj hauj lwm ntawm lub npuas yog tshwm sim tom qab dhau los ntawm lub hluav taws xob Circuit Court.
Piv nrog rau qib ib txwm muaj, qib hluav taws xob tau zoo dua qhov raug thiab rhiab heev vim tias lub raj tau txais infrared muaj qee qhov tau txais ntau yam rau infrared emission thiab siab dua rau lub teeb.
