Title: Device for dualing transmit frequency converter using switch in transmit diversity system
Inventor: PARK GWANG HO
IPC: H04B7/06
Filed: 2000-12-15
Abstract: PURPOSE: A duplicated transmit frequency converter system using switches in a transmission diversity system is provided to maximize the efficiency of a system by utilizing an unused transmit frequency converter as a redundancy. CONSTITUTION: A duplicated transmit frequency converter system using switches in a transmission diversity system consists of a transmit frequency conversion part(100), the first switch part(210), the second switch part(220), and an RF control part(300). The transmit frequency conversion part(100) is composed of active transmit frequency converters(110) and standby transmit frequency converters(120). If an IF signal corresponding to an arbitrary sector among a plurality of sectors is inputted from an IF block(10), the transmit frequency conversion part(100) modulates the IF signal into an RF signal and transmits the modulated signal. The RF control part(300), monitoring the fault status of the active transmit frequency converters(110), outputs switching control signals to the first switch part(210) and the second switch part(220) respectively if an abnormal state is generated. The first switch part(210), connecting the active transmit frequency converters(110) to the IF block(10), connects the standby transmit frequency converters(120) to the IF block(10) if the switching control signal is inputted from the RF control part(300). The second switch part(220), connecting the active transmit frequency converters(110) to an RF block(20), connects the standby transmit frequency converters(120) to the RF block(20) if the switching control signal is inputted from the RF control part(300).

Title: Discard Message Management Method In No.7 Signaling Network
Inventor: LEE SEONG U
IPC: H04L12/24
Filed: 2000-12-22
Abstract: PURPOSE: A method for managing discarded messages in a No.7 signaling network is provided so that an operator can confirm every discarded message information at any time as a workstation connected with a relevant STP(Signaling Transfer Point) collects discarded causes, discarded time and process information in real time for all signaling messages discarded in a signaling network and manages them as a log file. CONSTITUTION: If a signaling message from an OP(Originating Point) is received to an STP through an SL(Signaling Link)(S41), the MTP(Message Transfer Part) of the STP analyzes the received signaling message to determine whether it is to be discarded. At this moment, the signaling message processing part of the MTP checks the OP, the DP(Destination Point) and service information through header of the received signaling message and confirms whether a gateway restricting operation is necessary(S42). In case that the gateway restricting operation is required, the signaling message processing part discards the received signaling message, confirms the discarded cause, time and location of the signaling message(S43), and transmits this discarded message information to a workstation(S44).

Abstract: The invention relates to a method and to a shearing and compacting press for the production of pressed parts, preferably packages (20) from waste material, especially scrap and sheet clippings. The material used is pre-compacted in a first compacting step. In a second compacting step, the material, which has been pre-compacted to the width of the package, is subjected to intermediate compacting until the height of the package (20) is reached. In a third compacting step, final compacting of the material to the final width or length of the package (20) is carried out. According to the invention, the material is pre-compacted with a continuos force and optionally sheared until the compressor (3.1) reaches its final position. The compressor (3.2) is securely adjusted and guided to its end position on a parallel plane. Subsequently, the compressor (3.3) is guided in a position in which the compressor (3.1) releases the opening of the package chamber (2.3) when the compressor (3.1) is driven back. Finally, the compressor (3.1, 3.2, 3.3) is subjected to a pressure that is lower than the maximum pressure available in the compressors (3.1, 3.2, 3.3) at the beginning of the working and return strokes. The compressor (3.1) is subjected to maximum pressure for shearing and/or the compressors (3.2, 3.3) are supplied with maximum pressure to end pressing. The invention is also characterized in that the pressing pressure for the compressors (3.1, 3.2, 3.3) is gradually controlled depending on the degree of compression or the corresponding length.

Abstract: PURPOSE: A circuit for generating a warning sound by using a transistor is provided to precisely change the tone correspondingly to the change of a low frequency to a high frequency, thereby helping the warning sound recognition in a short time for prompt measurement. CONSTITUTION: A circuit for generating a warning sound by using a transistor includes a first timer(110) for generating a warning sound signal of a predetermined period, a control element such as a transistor(Q) to be turned on according to the warning sound signal output from the first timer for changing the warning sound signal according to own cut-off characteristics, and a second timer(120) for determining a tone corresponding to the warning sound signal output from the control element.

Abstract: PURPOSE: A method for transmitting a variable length packet using an HARQ(Hybrid Automatic Repeat Request) type is provided to reconfigure transmitted sub-packets and decode the sub-packets in case that sub-packets lost in a transmission and reception process are generated. CONSTITUTION: A transmission terminal determines a size of an encoder input packet and sizes of one or more sub-packets from a generated packet. The transmission terminal determines a transmission time of each sub-packet according to the determined sizes. The transmission terminal transmits each sub-packet to a reception terminal according to the determined transmission time.
