A high PT usually means that there is serious liver damage or cirrhosis. Other things to know: Some patients take a drug called Coumadin (warfarin), which elevates the PT for the purpose of thinning the blood. This is not related to having liver disease because it is the Coumadin causing the PT to be high.
A battery backup, or uninterruptible power supply (UPS), is primarily used to provide a backup power source to important desktop computer hardware components.
A power inverter simply turns the DC power delivered by the battery into 120-volt, 60-Hertz AC power. In a continuous UPS, the computer is always running off of battery power and the battery is continuously being recharged.ou could fairly easily build a continuous UPS yourself with a largish battery charger, a battery and a power inverter. The battery charger continuously produces DC power, which the inverter continuously turns back into 120-volt AC power.
