Abstract: A non-contact type gripper may include a gripping plate, a plurality of blowing holes, a plurality of suction holes and a cavity. The blowing holes may be formed at the gripping plate to inject a gas to an object. The suction holes may be formed at the gripping plate to suck the gas. The cavity may be extended from at least one of the blowing holes to suppress a pressure drop of the gas. The gas flowing through the cavities extended from the corner suction hole and the blowing holes between the adjacent suction holes may receive a low flow resistance. Thus, a pressure drop of the gas injected from the blowing holes may be suppressed by the cavities to maintain a pressure of the gas, thereby preventing a deflection of the corner portion of the object such as the semiconductor chip by a strong suction force. As a result, the non-contact type gripper may grip the object in the non-contact manner to prevent a contamination of the object.

Abstract: Disclosed are a hole location updating device, a hole location updating system, and a hole cutter. The hole location updating device including a hole cutter combiner providing a combination to a hole cutter that includes: a GPS circuit for detecting a global positioning system (GPS) position on the hole location updating device; a mobile communication circuit for providing access to a server through a mobile communication network; and a control circuit for transmitting the GPS position to the server by use of the mobile communication circuit in response to a wakeup signal.

Abstract: A golf coaching system and a method thereof are disclosed. The golf coaching system may include: a swing measurement device that measures at least one of a swing trajectory and a posture change during a swing; a striking prediction device that predicts striking by measuring at least one of a ball speed, a swing speed, and a launch angle; and a data analysis server that generates coaching information based on data measured by the swing measurement device and the striking prediction device.

Abstract: An exemplary embodiment has been made in an effort to provide a distance measuring apparatus, including: an output unit configured to output information; a memory configured to store map information of golf courses; a location acquiring sensor configured to acquire a current location; a distance measuring sensor configured to measure a distance to a target; a slope sensor configured to measure a tilt angle; and a control unit configured to read map information of the golf course corresponding to the current location from the memory, to calculate a first distance from the current location to a first point on the golf course by using the map information, to calculate a horizontal distance to the target by using the distance to the target and the tilt angle, and to output the horizontal distance to the output unit when the horizontal distance is within the first distance.

Abstract: A refrigerator includes: a main body including a storage compartment; an inner door rotatably coupled to the main body; an outer door rotatably coupled to a front of the inner door; a dispenser provided in the inner door and configured to supply water; and a water supply device provided in the inner door, and configured to supply a predetermined amount of water to a container, the water supply device including a sensor configured to detect a level of the water in the container, wherein the outer door may include: a door body including a dispenser opening configured to expose the dispenser in a state in which the outer door at least partially covers the inner door; and a door panel detachably mounted on the door body.
