The LTC®3562 quad output step-down regulator is designedfor multicore handheld microprocessor applications thatoperate from a single Li-Ion battery. Its four monolithic, higheffi ciency buck regulators support Intel’s mobile CPU P-Stateand C-State energy saving operating modes. The outputvoltages are independently controllable via I2C, and eachoutput can be independently started and SHUT down. Designerscan choose from power saving pulse-skipping mode orBurst Mode® operation, or select low noise LDO mode. Thespace-saving LTC3562 is available in a 3mm × 3mm QFNpackage and requires few external components.

Abstract:
The helicopter-electrical-box must SHUT off the helicopter power，protect the equipments of the helicopter when the helicopter power is failed.The tester for the helicopter-electrical-box based on AT89S52is used for testing the protect-ing function and measuring the delay time.Application results show this tester has some advantages,such as accurate mea-surement,high dependability,economical cost etc.
At can be given its arguments in a file. You can comment
out lines by preceding them with either # or -
characters. This is an easy way to temporarily disable
some commands.
The CONTINUE-command is most useful at the end of the
file. When this command is read, the file is started
again from the beginning. You can use it situations where
the machine is not SHUT down for the night and you want
to run some commands every day.
Control your PC with Mobile Phone-it controls your pc using mobile phone from anywhere in the world. A command can be send by mobile phone through sms.Based on the command ur pc performs tasks such as SHUT down,open file,play music etc.
