Abstract:
Disclosed herein is an optical circuit-type reformulated fuel detecting sensor device. The optical circuit-type reformulated fuel detecting sensor device includes: an optical source part generating optical signals having a single wavelength; a sensor part receiving the optical signals generated by the optical source part and outputting a reference optical signal and a sensed signal; a first photo-detector receiving the reference optical signal and outputting a reference optical output signal; a second photo-detector receiving the sensed signal and outputting a sensed optical output signal; an operation controlling part receiving the reference optical output signal and the sensed optical output signal and determining characteristics of fuel; and an output part receiving and outputting a result of the operation controlling part.
Abstract:
A wireless charging apparatus is provided. The wireless charging apparatus includes: an antenna that receives electrical waves; at least two charging power generators that generate charging power for charging a battery using the electrical waves received through the antenna; and a controller that senses a frequency of the electrical waves received through the antenna and that activates one of the at least two charging power generators according to a sensed result.
Abstract:
An optical oil component sensor and a sensing method using the sensor, which can identify similar fuel oil in real time. The optical oil component sensor includes a light source unit, a reference optical waveguide, configured to guide light thereinto, for receiving and outputting light emitted from the light source unit, a sensing optical waveguide, configured to guide light thereinto, for receiving and outputting light emitted from the light source unit, wherein a portion of the sensing optical waveguide is formed to be in contact with test target oil, a light-receiving unit for receiving both a reference light signal, output from the reference optical waveguide, and a test light signal, output from the sensing optical waveguide, and a control unit for identifying components of the test target oil by comparing optical properties of the reference light signal and the test light signal with each other.
Abstract:
A terminal and an operation control method thereof are disclosed. A terminal performs an authentication procedure upon receiving a tag device's information from the tag device. If the tag device is identified as a registered tag device in the authentication procedure, initial data corresponding to a function to control the terminal even in a power-saving mode or a lock mode is received from the tag device, and the function corresponding to the initial data is performed.
