  • Battery Detecting System
    Publication number: 20100045238
    Abstract: The invention discloses a detecting system for detecting whether a battery is connected to an electronic apparatus. The battery has a thermic resistor. The detecting system includes a power supply, a detecting resistor, and a detecting unit. The power supply generates a testing current. The detecting resistor is connected to the power supply and the thermic resistor. The detecting circuit is connected to a node between the detecting resistor and the thermic resistor. The detecting circuit detects a first voltage of the node and generates a detecting signal to determine whether the battery is electrically connected to the electronic apparatus.

  • Method and apparatus for a portable device
    Patent number: 7455447
    Abstract: A method for a portable device is disclosed. A reference clock is provided. A first time value and a first index are recording at a first time point. A second index is recorded at a second time point. The first time point and the second time point are counted according to the reference clock. The first index and the second index are calculated. A second time value is set according to the calculating result.
