Aspects for achieving individualized protected space in an operating system are provided. After a circuit schematic diagram of the circuit board and a circuit wiring diagram of the circuit board have been compared, the location of each electric contact is determined. An anode and a cathode assembly are positioned inside the chamber. The clamping circuit provides the reference voltage to the boost regulator at a level that is at least sufficient to cause the boost regulator to output a non-zero voltage. The first player to make a hand corresponding to a given circle will be awarded the primary pool in that circle.
