Abstract: PURPOSE: An apparatus and method for testing a loop-back of a wireless local loop(WLL) radio network terminal(RNT) is provided to directly control a RNT at a remote in a base station by testing the loop-back of a PCM(pulse code modulation) channel. CONSTITUTION: A modem(100) receives data from a base station or transmits received data to the base station. A micro controller(110) receives a PCM loop-back command from the base station through a signaling channel on a PCM common communication path and decodes the received PCM loop-back command. A control register(120) is connected to the micro controller(110), and controls a PCM loop-back function. A time switch(130) receives a network synchronous signal from the modem(100) and outputs the first control signal and a second control signal. The first multiplexer(140) extracts a signaling signal by the first control signal outputted from the time switch(130) and passes only data to be looped back. A second multiplexer(150) multiplexes the signaling data transmitted from the micro controller(110) to data through the first multiplexer(140) by the second control signal outputted from the time switch(130).

Abstract: PURPOSE: Provided is a bio-electric cell that organic material of wastewater is used as fuel and microorganisms of activated sludge is used as catalyst. Wastewater and activated sludge are filled around a cathode. At the cathode, microorganisms of wastewater or activated sludge are cultivated in an anaerobic condition, so only microorganisms, which use the cathode as electron acceptor, are cultivated selectively. Generally, microorganisms are covered with lipid film being nonconductive, so electron exchange is not occurred directly between microorganisms and electrode. Therefore, phosphate buffer solution is used as an electronic conductor in the bio-electric cell. Consequently, electrochemically activated microorganisms oxidize organic material of wastewater and electrons are produced by oxidation of organic material. The electrons are discharged to the exterior of cell of the microorganisms and are transferred to the cathode. Then, electric current is generated and wastewater is purified by oxidation of organic material. CONSTITUTION: The bio-electric cell is comprising by follow parts: graphite felts used as cathode and anode; a cation exchange resin to minimize resistance of the bio-electric cell; phosphate buffer solution for electronic conduction; an anode being aerobic condition; a cathode being anaerobic condition.

The workstation stores that all the channels are busy, and searches a service-available BS by using the resource using information and a map(S304). The workstation decides whether the service-available BS exists(S305). If so, the workstation transmits a decided BS ID to an RNC(S306). The RNC transmits BS mobile information including pilot information and a frame offset to the specific BS(S307). The specific BS transmits the BS mobile information to the MS through a broadcast channel(S308). The MS receives the information, and adjusts a synchronization with the newly-designated BS, then decides the newly-designated BS as an access BS(S309).

Abstract: PURPOSE: A method for generating digital filters is provided to equalize a loudspeaker. CONSTITUTION: A first digital data is provided, for a tolerance range for a target response curve of sound level versus frequency for the loudspeaker. A second digital data is generated, for an actual response curve of sound level versus frequency for the loudspeaker(1010). The first digital data is compared with the second digital data and it is determined whether the actual response curve is within the tolerance range(1020). If the actual response curve is not within the tolerance range, digital audio filters are iteratively generated, and the digital audio filters are applied to the second digital data to generate third digital data for a compensated response curve(1050,1060,1070). The frequency, amplitude and bandwidth of the digital audio filters are automatically optimized until the compensated response curve is within the tolerance range or a predetermined limit on the number of digital audio filters has been reached, whichever occurs first(1080).
