Abstract:
A vehicle detecting sensor using microbending of optical fiber and a vehicle detecting device using the same are provided to improve durability of optical fiber because a core is not influenced in a microbending although a top plate is moved down. A vehicle detecting sensor(1) using a microbending of optical fiber comprises optical fiber(30), a bottom plate(20), and a top plate(10). The bottom plate has a first body(23), a plurality of first protrusions(21), and a first groove(22). The first protrusions are protruded from the first body, and are separately arranged each other. The first groove is formed on the first protrusion in order to load the optical fiber. The top plate has a second body(13), a second protrusion(11), and a second groove(12). The second protrusion is protruded from the second body. The second groove is formed in a bottom of the second protrusion in order to load the second protrusion on the optical fiber. The top plate is moved toward the bottom plate side by pressure of a top side.
Abstract:
A SWNT-uhf combined sensor and gas insulated switchgear using the same is provided to secure high sensitivity detection while realize measurement frequency band of the UHF sensor in low cost. A SWNT-UHF combined sensor and gas insulated switchgear using the same is comprised of steps: sensing harmonic generated inside of the GIS by utilizing a UHF sensor(S101); sensing more than one of ion of the SF6 gas or products which are disassembled to the ion by utilizing the SWNT sensor(S102); deciding whether partial discharge of the GIS is generated or not based on the UHF sensor and the result of the SWNT sensor.
Abstract:
A data signal output terminal generates data to operate a signal processing application installed in an external device, modulates an analog signal with a preset frequency based on the generated data, and outputs the modulated signal through a data signal output terminal of an earphone plug. When the data signal output terminal is connected to an earphone port of the external device, the data signal output terminal is connected to a microphone terminal of the earphone port of the external device. [Reference numerals] (S510) Generate data;(S520) Convert the generated data into data signals in the form of frequncies;(S530) Output the converted data signals through an earphone plug

PURPOSE: A smart device, and a peripheral thereof, and a peripheral recognizing method thereof are provided for the peripheral to recognize the smart device by transmitting an authentication signal which includes a frequency pattern which is the intrinsic identification symbol of the peripheral when being connected to the smart device. CONSTITUTION: An earphone plug (21) is connected to an earphone port (11) of a smart device. If the earphone plug is connected to the earphone port, an authentication signal providing unit (22) transmits an authentication signal which is an intrinsic identification signal which is given to the peripheral to the smart device. The authentication signal is comprised in a form which arranges two or more serial unit signals having different frequencies on a time axis and includes a frequency pattern in which two or more frequencies are combined. A power supply unit (24) is supplied with a power from the smart device.
