Title: Apparatus and method for compensating time error of gsm terminal
Inventor: JUNG DONG SU
IPC: G04G3/00
Filed: 2001-10-19
Abstract: PURPOSE: An apparatus for compensating time error in a GSM terminal and a method therefor are provided to obtain very accurate time in spite of using a low-priced crystal by compensating a count error of a low frequency clock signal resulted from a change in an external condition(temperature, voltage) by using a very accurate high frequency clock signal. CONSTITUTION: A CPU(100) displays time information on an LCD and controls an overall time compensating operation. A scaling unit(110) scales a 13MHz high frequency clock signal. A frequency counter unit(120) counts a 65 MHz high frequency clock signal outputted from the scaling unit(110) and a currently inputted low frequency clock signal. A time compensating unit(130) compares counts values(Hc,Lc) outputted from the frequency counter unit(120) and calculates a compensation count value of the low frequency clock signal. An RTC(Real Time Clock) circuit(140) compensates a count value of the low frequency clock signal according to the count compensation value outputted from the time compensating unit(130). The high frequency signal counter(21) counts the high frequency signal outputted from the scaling unit(110) for a predetermined time period. A low frequency counter(22) counts the currently inputted low frequency signal. A frequency ratio calculating unit(31) compares the count values(Hc,Lc) and calculates a frequency ratio of the low frequency clock signal to the high frequency clock signal. A low frequency signal generator(32) calculates the currently inputted low frequency clock signal according to the obtained frequency ratio. A compensation value calculating unit(33) compares the calculated count value of the low frequency clock signal with an ideal count value of the low frequency clock signal and calculates a count compensation value. A compensation value updating unit(34) updates a count compensation value and transfers it to the RTC circuit(140) at certain periods.

Title: System and method for estimating sensitivity using physiological signal
Inventor: LIM JOA SANG
IPC: G06Q50/22
Filed: 2001-10-23
Abstract: PURPOSE: An emotion assessment system and method is provided to perform a real time emotion assessment over the internet by extracting plural measured physiological signal features and using a defined rule base on a basis of a two dimensional complex emotion model. CONSTITUTION: The method comprises several steps. An EEC(electroencephalogram), a PPG(Plethysmogram), and an SKT(kin Temperature) signal are measured by using sensors(201). A multiplexor selects addresses for the measured signals and the measured signals are transmitted to a sampling amp hold. The transmitted signals are converted into digital signals via an AD converter, and transmitted to a buffer. Then a clock is generated for synchronizing a multiple data transmission of the packet unit, and the buffer transmits the digital signals to a server of an emotion assessment system if an interrupt occurs(202). Each frequency feature is extracted from the measured signals(203), and normalized for expressing a current state fluctuation(204). The initial emotion values are initialized by using surveyed subjective emotion data, e.g. a tension and a release or a comfort and a discomfort(205). A user inputs subjective emotion states on a monitor, and then the subjective emotion value on the physiological signal is checked(206). A neutral emotion band is adjusted by using the input subjective emotion state and the measured physiological signals(207). The normalized physiological signal feature is accessed on a basis of a rule base, and an emotional state is assessed(208), and is filtered for eliminating a noise(209). The physiological signals and the emotion assessment result are stored at a database(210), and an emotion indicator displayed on a monitor in a real time(211).
