Patent ID: 8497604

Claim:
An apparatus for controlling power saving, the apparatus comprising: a sensing unit detecting a user's contact and generating an activation signal when a user's contact is acknowledged; a latch unit maintaining the activation signal which has been received from the sensing unit; an interruption unit forcibly interrupting the maintained state of the activation signal of the latch unit when an interruption signal is received from an external device; and a switch unit disposed on a current path that delivers power, and connecting the current path according to the activation signal from the latch unit, wherein the latch unit comprises, a first inversion amplifier inverting the activation signal and transmitting the inverted activation signal to the switch unit; and a second inversion amplifier re-inverting the inverted activation signal to generate the activation signal and feeding the activation signal back to the first inversion amplifier, wherein the switch unit connects the current path when the inverted activation signal is received from the latch unit.
