Abstract: A sensor device includes: a sensor panel including sensors arranged in a matrix form and sensor lines electrically connected to the sensors one-to-one; and a sensor driver configured to receive sensing signals from the sensors through the sensor lines, wherein the sensor driver is configured to simultaneously receive a first sensing signal from a first sensor using a first reference signal and a second sensing signal from a second sensor using a second reference signal, wherein the first reference signal and the second reference signal have a same waveform, a phase of the second reference signal is different from a phase of the first reference signal, and wherein a phase of the second sensing signal is different from a phase of the first sensing signal.

Abstract: The present invention relates to a digital sight for a hand-carried projectile-firing device and a method of controlling the digital sight. A digital sight for a hand-carried projectile-firing device according to an embodiment of the present invention is a digital sight for a hand-carried projectile-firing device, the digital sight including an inertial sensor package and a manual rotation device, wherein the inertial sensor package includes a gyroscope and an accelerometer module. In accordance with the present invention, equipment for measuring the firing direction of a hand-carried projectile-firing device such as a mortar is replaced with a digital sight for a hand-carried projectile-firing device, which reduces an estimation error while using a single medium-low level gyroscope, thus enabling the projectile-firing device to precisely and promptly fire a projectile and improving the operability thereof.

Abstract: Disclosed herein is a digital sight for a manually-portable shell-firing mortar. The digital sight includes a first accelerometer, a second accelerometer arranged perpendicular to the first accelerometer, a gyroscope arranged perpendicular to the first and second accelerometer, and a controller configured to calculate and display a re-firing direction varied from a primary-firing direction, using the first and second accelerometers and the gyroscope.

Abstract: An arc discharge apparatus includes a body unit including a housing and a transmissive member fixed to the housing, the housing having a coolant inlet and a coolant outlet, and an electrode unit on the housing, the electrode unit including an anode and a cathode facing each other, wherein the anode includes a main body portion connected to the housing, an anode tip coupled to the main body portion, and a cooling line in the anode and in contact with an inner wall of the anode tip, the cooling line being connected to the coolant inlet and to the coolant outlet.

Abstract: Disclosed are a self-diagnosis system of a home appliance and operation method of the same that self-diagnose and display a state of a home appliance having a self-diagnosis function, recognize and analyze the displayed self-diagnosis information, and provide proper service information corresponding to the state of the home appliance. A state of a home appliance having a self-diagnosis function is self-diagnosed, the diagnosed result is displayed as various images, such as a 7-segment image, QR code, and LED or sound type Morse code, self-diagnosis information displayed as the images is recognized and analyzed, and proper service information is provided to a user or a service provider, thereby easily checking a problem cause of the home appliance.
