Abstract:
A method by which a server controls a home device is provided. The method includes receiving a trigger signal generated by a sensor in a home in response to a mobile device being present at a specific location in the home, determining a home device corresponding to the specific location by using the trigger signal, selecting context information related to an operation of the determined home device from among context information received from the mobile device, and providing the selected context information to the home device.
Abstract:
A method by which a server controls plural devices includes receiving a trigger signal generated by a sensor in a home in response to a mobile device being present at a specific location in the home, determining devices corresponding to the specific location by using the trigger signal, receiving context information indicating a situation of a user from the mobile device, selecting context information related to operations of the determined devices from among the received context information by using keywords respectively related to the devices, each of the operations corresponding to each of the devices, and providing the selected context information to the devices respectively so that each of the devices performs the operations.
Abstract:
A method of inspecting an internal gas leak in a gas line includes providing an internal gas leak inspection device including a main valve and a pressure gauge in a main line between a first valve and a second valve in the gas line, forming an airtight space in the main line by shielding the main valve and the second valve, measuring a pressure variation of the airtight space using the pressure gauge, and determining whether or not the gas leak occurs, based on the measured pressure variation.
