Abstract:
An apparatus and method for gauging remainder is provided to measure remainder of a battery exactly by adding compensation voltage corresponding to the amount of load current to an output voltage of battery. In an apparatus and method for gauging remainder, a voltage detector(210) detects output voltage of a battery and measure a load current supplied to each load of electronic device from the battery. A voltage compensation unit(220) outputs compensation voltage corresponding to the amount of measured load current. A calculation unit(240) calculates the remainder of the battery corresponding to the add result of the voltage and compensation value after receiving output voltage and the compensation voltage.
Abstract:
A fractal scalable video coding system using a multi-processor and an image signal processing method of that are provided to decode and encode video signal by decoding a multi-processor into frame ratio different from each other according to a priority. A fractal decoder(140) receives the video signal corresponding to one screen. One screen has the single frame rate and single resolution. The fractal decoder divides one screen into a plurality of domain frames. A display part(150) reproduces the decoded video signal which is provided from the fractal decoder. The fractal decoder comprises a plurality of processor(141-144). Each processor divides video data corresponding to one screen according to the significance. The divided each domain frame is processed in parallel by a plurality of frame rates.

PURPOSE: A mobile phone and a driving method thereof are provided to minimize the damage on a device. CONSTITUTION: A memory(1200) stores a power lookup table necessary for the operation of plural elements according to the occurrence of an event. A converter(1320) applies the controlled power to the plural devices, and a PWM(Pulse Width Modulation) controller(1310) adjusts the pulse width of the power source to the converter. A DSP(Digital Signal Processor)(1110) controls the PWM controller according to the power lookup table corresponding to the occurring event. An error amplifier(EA) and a comparator(CP) reduces an error by comparing the input and output of the converter.
