The computers sometimes hangs. They shouldn't, but they do in spite of some faulty hardware or software. The computer should be reset then. This can be done if we are near, but what can we do if the computer is away from the computer?
Then JAKE helps.

Just plug JAKE into the serial port and RESET pin on the motherboard and start a small application. The application sends periodically special data to JAKE to ensure that the computer works right. If JAKE does not receive data - it resets the computer. Optionally JAKE can also control additional equipement such as modems, acces point. It has a special command to shut the power off and on to external power outlet.
