Proposed is an iridium alloy catalyst having reversible catalytic activity for an oxygen evolution reaction (OER), a hydrogen evolution reaction (HER), and a hydrogen oxidation reaction (HOR) by including an iridium alloy including iridium (Ir) and nickel (Ni). The iridium alloy catalyst according to the present disclosure is rapidly converted to an iridium alloy catalyst in an oxide form and an iridium alloy catalyst in a metallic form according to applied voltage by controlling its crystallinity. Thus, even in case an oxide layer is formed after the OER, the oxidation layer disappears during the HER and HOR and the properties of an iridium metal catalyst remain, thereby maintaining HER/HOR performance.

Iridium alloy catalyst having reversible catalytic activity and preparation method thereof

A vehicle infotainment system for performing a large file transfer (SATA), music (USB), phone projection (CarPlay/Android Auto/MirrorLink), a modem (USB) and a phone mirroring (MHL) function using a millimeter wave short-range communication method in a band of 30 GHz to 300 GHz for a link between the vehicle infotainment system and a smartphone.

Vehicle infotainment system and method of controlling the same

An emergency rescue request notification method using an infotainment system and a system therefor are provided. The emergency rescue request notification method in the vehicle includes detecting an accident of the vehicle, collecting information corresponding to the detected accident, generating an emergency rescue request message based on the collected information, searching for an FM radio channel with the highest receive sensitivity, changing and transmitting a program type of the found FM radio channel to a specific value using an FM radio data system (RDS) message, and transmitting the emergency rescue request message over the found FM radio channel.

Infotainment system for emergency rescue request notification and method thereof

An active control system of a vehicular dual microphone and a control method thereof control a beamforming area of a microphone installed adjacent to each of a driver seat and a passenger seat to be directed toward a person (utterer) who utters a voice command. The control system and method use sitting height information and seat position information of the driver or the passenger and use passenger seat riding information. The control system determines output from a mouth shape change detection unit and the user and seat position detection unit, controls microphone beamforming of the driver seat according to the determined microphone beamforming control mode, and selectively adjusts a specific microphone gain according to the determined microphone beamforming control mode to separately control microphone beamforming of the driver seat and the passenger seat.

Active control system for a vehicular dual microphone and a control method thereof

Methods of manufacturing a CIGS thin film for a solar cell are provided. According to the method, a CIGS thin film having an ideal double band gap grade structure with a large particle size may be obtained by heat-treating a solution-treated CIG oxide thin film by a three-step chalcogenization process. Accordingly, performance of the solar cell may be improved.

Method for manufacturing CIGS thin film for solar cell

An audio, video, and navigation (AVN) system includes a battery voltage detection circuit configured to detect an output voltage of a main battery; an e-call power controller configured to output power of a back-up battery (BUB) based on a result of detecting the output voltage; and a central controller configured to receive the power of the BUB and to generate an accident occurrence message when an airbag inflation signal is received.

Method for operating audio, video, and navigation (AVN) system, AVN system, and vehicle including the same

A mobile communication terminal, and a method of backing up and restoring calibration data thereof disclosed, thereby enabling a terminal to repair damage to radio frequency calibration data. The present invention includes a radio frequency calibration data checking unit comparing a checksum value of radio frequency calibration data stored in an internal terminal memory to a checksum of backup data value stored in a SIM card according when the terminal is turned on, the radio frequency calibration data checking unit determining whether the radio frequency calibration data stored in memory is the same as the data stored on the SIM radio frequency calibration data recovering unit for restoring the radio frequency calibration data from the SIM card.

Mobile communication terminal having a radio frequency calibration data recovering function and a method of backing up and restoring calibration data

A network search method for a mobile communication terminal is disclosed. In one example embodiment, a mobile communication terminal employing a Digitally Controlled Crystal Oscillator (DCXO) performs a network search method including the act of searching for a frequency using a value stored in an Automatic Frequency Control (AFC) mode.
