Abstract: PURPOSE: A method for preventing chattering appearance is provided to prevent a chattering appearance generated at a power measuring system by clearing a pulse input flag in software by a micro computer. CONSTITUTION: In a method for preventing chattering appearance of a transmission unit in a power measuring system, whether a pulse input flag is set is judged(300). The pulse input flag is to indicate whether a counter is increased and a working is performed. If the pulse input flag is not set, the step(300) is repeated. If the pulse input flag is set, a pulse count is increased by '1'(301). Whether an input pulse transitions to a low state is judged(302). In a case where the input pulse transitions to the low state(when two magnets increasingly is adjacent to each other), a pulse input flag set and a pulse count are cleared(303). In a case where the input pulse transitions from a low state to a high state, there is checked whether the pulse count is increased up to a predetermined number(304). If the pulse count is increased up to the predetermined number, the pulse input flag set and a pulse count are cleared(305), and the a count of a power measuring system is increased when two magnets are separated from each other(306).

Title: Wirelessly receiving apparatus of radio interface unit in wireless local loop system
Inventor: BAE JONG JIN
IPC: H04B1/16
Filed: 1998-12-30
Abstract: PURPOSE: A wirelessly receiving apparatus of a radio interface unit(RIU) is provided to improve receiving sensitivity of the RIU, by implementing a wireless receiver for wirelessly interfacing with a base station of the RIU, and by configuring dual low noise amplifier(LNA) having a low noise index and a LNA having a high gain to implement the wireless receiver. CONSTITUTION: A wireless local loop(WLL) system is composed of a radio interface unit(RIU), a base station, a base station controller, and a central office. The WLL system configures a link by using a wireless system instead of a wire from the central office to subscriber terminals. A wirelessly transmitting apparatus of the RIU in the WLL system comprises an antenna duplexer(30), a modem(VCTCXO)(31), a phase locked loop(PLL)(32), a radio frequency(RF) voltage controlled oscillator(VCO)(33) and an intermediate frequency(IF) VCO(35), a splitter(34), a splitter(36), a first low noise amplifier(LNA)(37), a first RF(Radio Frequency) SAW(Surface Acoustic Wave) filter(38), a second LNA(39), a second RF SAW filter(40), a down-mixer(41), an IF SAW filter(42), an automatic amplifier(43), a coupler(44), an IF amplifier(45), a demodulator(46), a data buffer(47), a received signal strength indicator(RSSI) detector(48), and an AGC controller(49). The splitter(34) outputs a 2455MHz local signal with an up-mixer. The splitter(36) outputs a 140MHz local signal with a modulator. The first LNA applies a low noise amplification for RF signals received from a receiving path of the antenna duplexer. The second LNA applies the low noise amplification for the RF signals again. The down-mixer mixes the RF signals with the 2455MHz local signal, and converts the mixed signals into 70MHz IF signals. The IF SAW filter intercepts spurious-band signals of the converted IF signals. The AGC amplifier amplifies sizes of the converted IF signals at regular levels. The coupler couples the amplified IF signals from a main line to a sub line. The IF amplifier amplifies the amplified IF signals to sizes necessary in the demodulator at regular levels. The demodulator receives the 140MHz local signal, and demodulates the amplified IF signals to orthogonal component I(In-phase)/Q(Quadrature) data. The data buffer matches the I/the Q data with an output impedance, and outputs the data to an analog to digital(A/D) converter. The RSSI detector measures strength of the amplified IF signals from the AGC amplifier, and converts the strength into DC(Direct Current) levels. The AGC controller outputs a Tx gain control signal. The Tx gain control signal controls the amplifying levels of the AGC amplifier and controls transmission signal gain, according to a detected DC voltage from the RSSI detector and a gain control signal of a central processing unit(CPU).
