  • Energy-saving control interface and method for power-on identification
    Patent number: 6687830
    Abstract: An energy-saving control interface for power-on identification utilizes a first switch to start to sense and identify data. A second switch is connected to a sensing/scanning circuit for powering off the sensing/scanning circuit when a timer has reached its count. A third switch is used to control whether to supply power to a security control unit, wherein the security control unit is supplied with power immediately when the sensing/scanning circuit completes data identification. A power supply is connected with a fourth switch controlled by a confirmation signal from the security control unit, such that the security control unit determines whether to activate the power supply.
