Patent ID: 8890372

Claim:
An electrical system comprising: a power input; at least one power output comprising an electrical outlet configured to be electrically coupled to at least one external device; a first user input device configured to provide a start up input; a second user input device configured to provide a time select input; and an internal assembly comprising: a power switch circuit electrically coupled between the power input and the at least one power output, the power switch circuit being configured to receive a first power signal from the power input and comprising a control mechanism configured to open and close to regulate a flow of the first power signal to the at least one power output; a power conserve circuit electrically coupled to the power switch circuit, the power conserve circuit being configured to receive the first power signal from the power switch circuit, to receive the start up input from the first user input device, and to attenuate the first power signal to a second power signal and a third power signal at different times; a power supply circuit electrically coupled between the power switch circuit and the power conserve circuit, the power supply circuit being configured to receive the second power signal and the third power signal at different times from the power conserve circuit, to convert the second power signal into a fourth power signal and a fifth power signal, to convert the third power signal into a sixth power signal and a seventh power signal, and to provide the fourth power signal and the sixth power signal at different times to the power switch circuit; a control circuit electrically coupled between the power supply circuit and the power switch circuit, the control circuit being configured to receive the fifth power signal and the seventh power signal at different times from the power supply circuit and to receive the time select input from the second user input device; wherein: the time select input comprises a length of time input; the control circuit is configured to activate a countoff register set to run for the length of time; and while the control mechanism is closed and the power conserve circuit is not receiving the start up input: the control circuit references the countoff register to determine if the length of time has elapsed; and the control circuit provides a termination power signal to the power switch circuit when the length of time has elapsed and opens the control mechanism to prevent the first power signal from passing to the at least one power output and through the power conserve circuit.
