Further provided is a method of manufacturing a hot-press part including: coating a metal on the steel sheet on a steel sheet; annealing the metal coated steel sheet; zinc plating the annealed steel sheet by dipping in a molten zinc plating bath; heating the zinc-plated steel sheet; and press forming the heated steel sheet.

Abstract: The present disclosure relates to an X-ray device, and an X-ray device according to an embodiment of the present disclosure comprises: a radiator configured to radiate an X-ray; a distance measurement sensor configured to measure a value of a distance to an object; and a controller configured to acquire a first separation distance between an X-ray radiation focal point of the radiator and a subject, and control operation of the radiator based on the acquired first separation distance. Through these, the radiation of the X-ray can be prevented without a physical skin guard when the subject approaches within a certain distance from the radiator, thereby preventing the increase in the size caused by the installation of the physical skin guard, and a process of manually setting a strength of the X-ray radiation output according to the thickness of the subject can be omitted, thereby improving easiness of the X-ray imaging and reducing the time for the X-ray imaging.

Abstract: An X-ray imaging device may comprise: a radiation unit configured to preheat a filament and radiate an X-ray; a detection unit configured to detect shake of the radiation unit and generate information on the shake of the radiation unit; and a controller configured to determine a degree of the shake based on the information on the shake received from the detection unit and control an operation of the radiation unit depending on the determined degree of the shake. Therefore, the device can acquire a clear X-ray image without blur, and furthermore has effect in that unnecessary radiation exposure by re-photographing due to the blur of the X-ray image can be minimized.

Abstract: A power supply apparatus for an X-ray imaging system. A capacitor unit including a plurality of capacitor cells is connected in series to a single cell battery, such that the capacitor unit is charged using the single cell battery. Only when respective capacitor cells of the capacitor unit are charged, respective balance circuits corresponding to the respective capacitor cells are controlled to be turned on. When the balancing of the respective capacitor cells is completed, the balance circuits are opened. Accordingly, the power consumption of the capacitor cells is minimized.

Abstract: A radio control method for a vehicle and a system for the same are disclosed. The method take advantage of radio data system (RDS) data in a radio broadcast system prevents unexpected initialization of a preset channel during utilization of a preset function. The radio control method for a vehicle includes receiving information about radio channel selection achieved by a preset function, and when the selected radio channel does not include radio data system (RDS) information, updating a preset slot in a manner that a new radio channel including the RDS information is designated to the preset slot.

Abstract: A system for diagnosing a vehicle terminal includes a WiFi dongle coupled to an external connection terminal of a vehicle to connect wireless communication between a vehicle diagnosis device and the vehicle terminal. A vehicle diagnosis device is configured to transmit an inspection start command to the vehicle terminal through the WiFi dongle, and inspect at least one of a Bluetooth function and a voice recognition function. The vehicle terminal is configured to download and store phone book data through Bluetooth paired with the vehicle diagnosis device, detect a phone book name in the stored phone book data, and enter a call making mode. The vehicle diagnosis device inspects the Bluetooth function according to whether the phone book data of the vehicle terminal is downloaded, and inspects the voice recognition function.

Abstract: A method for emergency service using telematics includes: attempting to transmit an emergency service request message to a telematics center through mobile communication when a telematics terminal receives an emergency signal; confirming, by the telematics terminal, whether the telematics terminal processes the emergency service in attempting to transmit the emergency service request message; informing a vehicle terminal of the fact that the emergency service is not processed if it is confirmed that the telematics terminal does not process the emergency service; and receiving, by the vehicle terminal, the emergency service request message from the telematics terminal to process the emergency service through TV white space (TVWS) communication, thereby extending an emergency service coverage using the telematics.
