Disclosed herein is a food management system, a computing apparatus, and a refrigerator capable of dealing with frequent changes in a state of food stored in the refrigerator by tracking a state change of food in the refrigerator, without manual inputs from a user, and capable of expanding a service associated with food management, such as food purchase and capable of improving user convenience and accuracy of food management.

Food management system, computing apparatus and refrigerator

A food management system includes a computing apparatus, and a refrigerator including a storage chamber and configured to transmit an image of the storage chamber to the computing apparatus. The computing apparatus may include a communication device; and a processing device configured to identify a food from an image received from the refrigerator through the communication device and to transmit information related to the food identified by the refrigerator through the communication device. The processing device may identify the food using different processes from different images.

Refrigerator, and system and method for controlling same

A cleaning robot includes a user interface to display a map image including one or more divided regions, and the user interface displays an icon corresponding to a state value of a main device on the map image.

Cleaning robot and method for controlling cleaning robot

A portable facility failure diagnosis device using detection of radiation ultrasonic waves, comprising: an ultrasonic sensor array; a data acquisition board (DAQ board) in which an electronic circuit for acquiring ultrasonic signals at a sampling frequency of the ultrasonic signals sensed by the ultrasonic sensor array is mounted on a substrate of the data acquisition board (DAQ board); a main board in which an operation processing device that processes the ultrasonic signals received from the DAQ board is mounted on the substrate and the processed ultrasonic sound source information to a display device; a data storage medium storing data processed in the operation processing device of the main board; a display device visually displaying the data processed; and an optical camera picking up an image of a direction.

Portable ultrasonic facilities diagnosis device

A cleaning robot is provided. The cleaning robot includes a sensor configured to sense obstacle information, and a controller configured to generate a map based on sensed values obtained by the sensor, analyze a structure of the generated map by detecting a region segmentation point from the map, and generate a map image based on an analysis result.

Cleaning robot and method of controlling the cleaning robot

Provided is a substrate processing apparatus. The substrate processing apparatus includes a first tube defining an inner space, a substrate holder in which a plurality of substrates are vertically stacked in the inner space of the first tube, the substrate holder defining a plurality of processing spaces in which the substrates are individually processed, a gas supply unit having a plurality of main injection holes each of which is vertically defined to correspond to each of the processing spaces to supply a gas into the first tube, and an exhaust unit configured to exhaust the gas supplied into the plurality of processing spaces in the first tube to the outside. The exhaust unit includes a plurality of exhaust holes facing the main injection holes and vertically arranged in a line to correspond to the processing spaces. Therefore, the gas may smoothly flow on the substrate.

Substrate processing apparatus

A solar battery is partially attached to each blade of a blind. The position of each blade is adjusted based on position information such that each blade tracks sunlight. Electric energy obtained by the generation of electricity using an indoor illumination source is used to charge a battery. In addition to the generation of electricity, some of the blades are folded to let in light.

Blind with solar batteries and control method thereof

Disclosed is an air conditioner, in which, when a temperature sensor is rotated, the rotating speed of the temperature sensor is increased or the temperature sensing cycle is elongated in a rotating section where an object does not exist rather than in a rotating section where the object exists. Further, the rotating speed of the temperature sensor is increased or the temperature sensing cycle is elongated if the object is located at a short distance from the air conditioner rather than if the object is located at a normal distance from the air conditioner, and the rotating speed of the temperature sensor is decreased or the temperature sensing cycle is shortened if the object is located at a long distance from the air conditioner rather than if the object is located at a normal distance from the air conditioner.

Air conditioner and temperature sensor

Disclosed herein are a refrigerator and a defrost control method thereof that are capable of sensing an amount of frost formed on an evaporator based on a change amount of absolute humidity in the refrigerator to control a defrost operation. A defrost control method of a refrigerator including a storage chamber and an evaporator to cool the storage chamber, includes sensing absolute humidity in the storage chamber, determining an estimated amount of frost formed on the evaporator using time segments in which the absolute humidity in the storage chamber decreases, and controlling a defrost operation based on the estimated amount of frost. According to the present embodiments, it is possible to perform the defrost operation at the point of time for optimum defrost, thereby maximizing energy efficiency and cooling efficiency.
