Abstract:
Provided is an electron mediator system, which may include a first transition metal complex and a second transition metal complex, wherein a working potential of the electron mediator system may be substantially the same as a molar average of a working potential of the first transition metal complex and a working potential of the second transition metal complex.
Abstract:
An air purifier is provided. The air purifier includes a plurality of filters, a driving unit configured to individually move the plurality of filters, and a processor configured to control the driving unit so that at least one of the plurality of filters is disposed in an air passage in the air purifier according to an air state.
Abstract:
An electronic device is disclosed. The electronic device comprises: a gas sensor having different sensitivities in temperature for each of a plurality of gases; and a processor for calculating a concentration of at least one of a plurality of gases on the basis of an output value of the gas sensor for different temperature sections.
Abstract:
A test device includes a plurality of transceivers that respectively transmit a wave to a test target point of a test object, respectively receive a wave reflected, scattered, or refracted from the test object, and respectively output a signal generated in response to the received wave; a combiner that combines the plurality of received signals generated by the plurality of transceivers; and a plurality of switches that are opened or closed to transfer the plurality of received signals to the combiner or block the plurality of received signals from being transferred to the combiner.
Abstract:
A memory system includes an error checking and correction (ECC) engine configured to perform error checking and correction of data temporarily stored in a first memory array and data read out from the first memory array according to a first method, and perform error checking and correction of data stored in a second memory array after read out from the first memory array and data read out from the second memory array according to a second method, wherein the first method and the second method are selected in response to a control signal having at least a first logic level, and the second method checks and corrects data errors occurring at a higher rate compared the first method.
