Title: Method for sensing exhaust port closure of gas boiler
Inventor: BAEK SEONG HAK
IPC: F24H9/20
Filed: 1998-12-29
Abstract: PURPOSE: A method is provided to prevent the increase of rotating numbers from misconceiving as the closure of exhaust port by comparing the difference of the fan rotating numbers when fan driving voltage is set in maximum and in minimum with the difference in a normal state. CONSTITUTION: A sensor senses the rotating number of a fan for a certain time in maximum fan driving voltage and senses the rotating number in minimum voltage. The difference between the maximum rotating numbers and the minimum rotating numbers is output and compared with the standard difference in a microcomputer. When the difference is more than the standard difference, the gas is supplied and ignited. When the difference is less than the standard difference, the gas supply is closed.

CONSTITUTION: A radio interface unit (RIU) of a wideband-wireless local loop (WLL) system for a U-interface, comprises a radio frequency (RF) unit (41), a modem (42), a time switch (43), a D-channel processor (44), a controller (45), and the U-interface (46). The RF unit receives a radio signal to convert the signal into an analog signal, and outputs the analog signal to the modem or converts a digital signal of the modem into an analog signal to convert the analog signal into a radio signal, then transmits the radio signal to a base station. The modem converts the analog signal of the RF unit into a digital signal to despread the digital signal, and outputs service information to the time switch or spreads the service information to output the information to the RF unit. The time switch outputs the service information to the U-interface or switches the service information in a time slot, then outputs the information to the modem. The time switch supplies a clock and a frame synchronous signal to the U-interface. The D-channel processor outputs integrated service digital network (ISDN) D-channel messages of the time switch and the U-interface to the controller, or outputs an ISDN D-channel message of the controller to the time switch and the U-interface. The controller performs controlling processes for operations of each block in the RIU. The U-interface performs activation/deactivation processes for 2B1Q line coding and a layer1, and removes echoes to perform functions of a U reference point of an ISDN, and interfaces a network terminal (NT) of the ISDN with the RIU.
