Provided are an apparatus for multiplexing Gigabit Ethernet frames and an apparatus for demultiplexing 10-Gigabit Ethernet frames. The apparatus for multiplexing Gigabit Ethernet frames includes at least one pre-processing unit, a multiplexing unit, an SDR/DDR conversion unit, and a control unit. The at least one pre-processing unit receives Gigabit Ethernet frames, converts the Gigabit Ethernet frames into 10-Gigabit Ethernet frames, and outputs the 10-Gigabit Ethernet frames. The multiplexing unit receives the 10-Gigabit Ethernet frames, time division multiplexes the 10-Gigabit Ethernet frames in frame units, and outputs the time division multiplexed 10-Gigabit Ethernet frames as first data. The SDR/DDR conversion unit, which converts the first data into second data having two 32-bit bus structures and outputs the second data. The control unit outputs a first control signal in response to an output request of the pre-processing unit.

A latch type optical communication module, designed to9 be easily mounted and detached to a system port having a cage by means of a latch. The optical communication module is provided with a latch: The latch may be rotated around a hinge shaft fixed to both sides of a receptacle while being inserted into latch holes penetrating both ends of the latch. When the latch is rotated and then allows latch drivers to force a slider upward, the slider raises a fixing tap of the optical communication module inserted into the system port, thereby allowing the optical communication module to be detached from the system port. With the construction of the optical communication module, the plurality of additional components are not required for the optical communication module, thereby lowering manufacturing costs, and the optical communication module can be detached from the system port without any tool and any influence against adjacent optical communication module.

This invention relates to transparent polycrystalline ceramic scintillators and methods of preparing the same. The invention also relates to gadolinium-yttrium oxide ceramic scintillators with europium added as an activator, which are optically transparent and whose cubic structures are maintained even when gadolinium oxide constitutes more than 50% of the scintillator. The scintillators of the present invention also have high light yield due to excellent luminescent characteristics in the visible light region.

A simultaneous write duplexing system with a fault-tolerant function and a method therefore are described. A serial-parallel converter is located between serial buses and parallel buses, and converts parallel data received from the parallel buses into serial data including unit identification information of a data destination. A buffer unit stores serial data received from the serial-parallel converter. A scheduler decides an output order of serial data stored in the buffer unit. A switching unit outputs serial data output from the buffer unit to a serial bus connected with a unit indicated by unit identification information of the serial data, according to the output order of the scheduler, and to a standby module for backing up system functions. Therefore, it is possible to connect an active module to a standby module spaced from the active module by several meters by allowing communication between the active module and the standby module.

A patch-type extrinsic Fabry-Perot interferometric fiber optic sensor and a real-time structural vibration monitoring method using the same are disclosed. The patch-type extrinsic Fabry-Perot interferometric fiber optic sensor is provided by combining the existing EFPI (Extrinsic Fabry-Perot Interferometer) fiber optic sensor with a direction-detecting sensor which can acquire direction information of a strain of a structure, which can solve a signal distortion problem occurring in the existing EFPI fiber optic sensor through a simple signal process. The patch-type extrinsic Fabry-Perot interferometric fiber optic sensor includes a piezoelectric material which can apply a control force to the existing EFPI fiber optic sensor, and a self-sensing bridge circuit for extracting the direction information when the piezoelectric material is used as an actuator, so that the sensible range of strain can be extended and the piezoelectric material can directly be used as the actuator based on the sensed signal.
