  • Patent number: 11475114
    Abstract: A terminal for checking a security request level of a fingerprint verification request is provided. The terminal includes a fingerprint recognition sensor configured to acquire a fingerprint image; and a controller configured to check a security request level of a fingerprint verification request when the fingerprint verification request is received, to determine an verification level depending on the security request level, and to perform fingerprint verification in a manner corresponding to the verification level by using the fingerprint image. The controller controls the fingerprint recognition sensor to acquire a fingerprint image of a first level when the security request level is less than or equal to the security request level of a previous verification request that has been completed before the fingerprint verification request, and an elapsed time from the previous verification request is within a threshold time.

  • Patent number: 8793519
    Abstract: A method for reducing power consumption based on a motion sensor and a portable terminal adapted to the method are disclosed. The method includes terminating driving of a motion recognition program according to whether an input is detected by at least one sensor unit disposed in the portable terminal, and switching a mode of a controller included in the portable terminal into a motion recognition deactivation mode. The motion sensor-based portable terminal can reduce the power consumption, thereby lengthening the life span of the battery. The user can use the motion sensor-based portable terminal for a long period of time without frequently recharging its battery.

  • Patent number: 8116405
    Abstract: A method and apparatus for time synchronization (TS) method using GPS information in a communication system synchronizing the time of slave nodes, which do not have a GPS receiver, by using GPS information of a node having a GPS receiver. The method includes the steps of extracting 1PPS, TOD, 1PPS_en, and clocks using GPS signals by a grand master node having a GPS receiver, stabilizing the signals, generating a sync message for TS, and transmitting the sync message to a slave node; receiving the sync message by the slave node and conducting a TS operation using OFCC synchronization technology extracting 1PPS, TOD, and 1PPS_en signals using the modified TOD information by the block and delivering to a stabilization block of the slave node for stabilization; and redelivering to the TS block to update TOD information and generate a sync message for TS of a second slave node.

  • Patent number: 7747233
    Abstract: An apparatus and method for supplying information so that power consumption in a digital broadcast receiving terminal can be reduced and a user can use an appropriate antenna depending on a situation. The digital broadcast receiving terminal includes an external antenna detachably assembled with the outside of the terminal a switch unit for selecting any one among the internal antennas and the external antenna, and a signal-receiving condition sensing unit capable of sensing the signal-receiving condition of the internal antennas and the external antenna. If it is impossible to receive the digital broadcast signal by using the internal antennas, the external antenna is used. If the external antenna is mounted, power is supplied only to an RF unit connected to the external antenna and the power supply to the remaining RF unit is cut off, reducing power consumption.
