摘要:
The invention is directed to heterocyclic indene derivatives useful for β-amyloid plaque imaging, their radiolabeled compounds and their preparation methods. The compounds of the invention are easily labeled with radioisotopes and have high affinities to β-amyloid depositions, thus they facilitate diagnosis of Alzheimer's disease by imaging the distribution of β-amyloid depositions.

Provided are a hybrid optical transceiver module having an optical amplifier packaged thereto for outputting a high-power optical signal to remove problems regarding narrow emission angle and optical alignment, and a passive optical network (PON) system having an improved optical network terminal (ONT) accommodation capability using the hybrid optical transceiver module. The hybrid optical transceiver module includes a first package in which an LD (laser diode) is packaged, and a second package in which SOA (semiconductor optical amplifier) and a PD (photo diode) are packaged. The first and second packages are coupled to be one package so as to output a high-power optical signal.

The present invention discloses a cutter for trimming a tread of a tire. The cutter includes a cutting plate which has a plurality of cutting slits sequentially formed at a lower end thereof to cut over-flow rubber formed on the tread of a tire; and a handle which is coupled to the cutting plate, and is configured for a user to hold to cut the over-flow rubber using the cutting plate. The cutting plate has a plurality of grooves formed on a rear surface thereof to vertically guide and discharge the over-flow rubber cut by the cutting slits. According to the present invention, it is possible to prevent a reduction in a lifespan due to a decrease in hardness of a cutting plate caused by friction heat generated in a process of using the cutter for trimming the tread of a tire, and prevent over-flow rubber discharged in a process of trimming the tire from scattering.

Provided is an optical line terminator (OLT) to recover packet data and a clock from an optical signal including a silent interval. The OLT may receive packet data and a clock from at least one optical network unit (ONU). Even in a silent interval in which the at least one ONU does not transmit packet data, the OLT may successfully recover the clock.
摘要:
A method and system for generating a developer interface using a loaded program. The method of generating a developer interface may share a plurality of components included in a loaded program through a communication interface, and generate a new program using components selected from among the plurality of shared components through the developer interface.

A Passive Optical Network (PON)-based system and method for providing handover between Optical Network Terminals (ONTs) are provided. The PON-based system may include an Optical Line Terminal (OLT), and an ONT to relay communication between the OLT and a mobile terminal. When the mobile terminal is connected to the ONT, the ONT may transmit a WiFi location update alarm message to the OLT, and the OLT may update a Look-Up Table (LUT) in response to the WiFi location update alarm message.

Disclosed herein are a remote node and a telephone station terminal in a passive optical network (PON). The remote node includes an optical circulator that transmits downlink signals input from a downlink optical backbone network to a wavelength distributor and transmits uplink signals input from the wavelength distributor to an uplink optical backbone network different from a downlink optical backbone network; and a wavelength distributor that distributes the downlink signal input from the optical circulator into a plurality of wavelengths to be connected to an optical distribution network and connects the uplink signals input from the optical distribution network to the optical circulator.
摘要:
A method of transmitting an Operations, Administration and Maintenance (OAM) message and of processing an error in a Passive Optical Network (PON) system is provided. Using an OAM packet format that may be used in common in the PON system, a process of transmitting or receiving an OAM message may be simplified, an efficiency of the process may be increased, and an Optical Network Unit (ONU) may be managed at a high speed.
摘要:
An optical subscriber network for power reduction is provided. The optical subscriber network may include an Optical Line Terminal (OLT) and an Optical Network Terminal (ONT). The OLT may manage a plurality of ONTs by classifying the plurality of ONTs into a sleep group, and may multicast a sleep allowance message only to ONTs included in a predetermined sleep group.
