IPC: F24C3/12
Filed: 2001-11-27
Abstract: PURPOSE: A safety device for a gas range is provided to reduce gas consumption and prevent fire accidents caused due to carelessness of a user. CONSTITUTION: A safety device comprises a pressure sensor rod(1), a longer pressure sensor unit(5) and a shorter pressure sensor unit(6) connected to the pressure sensor rod, a current cut-off rod(3) and a contact rod(4). When a cook pot(13) containing foods(14,15) is put on a fireball(12) of a gas range, the pressure sensor rod is lowered downward due to the weight of the cook pot, and the longer pressure sensor unit and the shorter pressure sensor unit press the right sides of the current cut-off rod and the contact rod. Subsequently, the left sides of the current cut-off rod and the contact rod rotate on a shaft(16) and stop with a spring(2). When the amount of the food contained in the cook pot decreases since the food is heated and the moisture is evaporated from the food, only the current cut-off rod is lowered and presses a contact line(7), to thereby cut off the current generated from a thermo-couple(9), permit a magnet induction valve(10) to return to its original position, and cut off gas supply.

IPC: H04L12/56
Filed: 2001-12-28
Abstract: PURPOSE: An R-P setup method in a mobile communication system is provided to store an RTD(Round Trip Delay) value through an ICMP(Internet Control Message Protocol) echo request message, and to limit an R-P setup from the start for a PDSN in which the RTD value does not satisfy a reference value, thereby minimizing data transmission delay by preventing a long-distance PDSN from being selected. CONSTITUTION: A PCF(Packet Control Function) transmits an ICMP echo request message to a PDSN, and measures an RTD of the PDSN(41). If a new call arrives, the PCF writes a PDSN list with the RTD of the responding PDSN(42), and calculates which PDSN includes a subscriber with a module for a subscriber number(43). The PCF decides whether an RTD level of the PDSN satisfies a reference value(44). If so, the PCF attempts an R-P setup in order of the PDSN list(46). If the RTD level does not satisfy the reference value, the PCF repeats a process of performing the R-P setup with the next PDSN of the subscriber PDSN(45).
