摘要:
Disclosed is a method for retrieving a label in a portable terminal. The method includes obtaining a label image photographed through a camera, extracting characters included in the label image and recognizing the extracted characters, detecting at least one label including the recognized character from a label database including multiple labels and information on the multiple labels and constituting a preliminary label candidate group including said at least one label, detecting an image characteristic of the label image, detecting at least one label having an image characteristic, which is similar with the detected image characteristic, from the preliminary label candidate group, and constituting a final label candidate group, and providing each of said at least one label included in the final label candidate group and detailed information corresponding to each of said at least one label.

Sump assembly for a dishwasher holds washing water and supplies the washing water to spray nozzles. The sump assembly includes a sump housing for holding washing water, a pump provided to the sump housing for pumping the washing water, and a soil chamber housing for receiving a specified amount of the pumped washing water, wherein a sensor assembly is provided to the soil chamber housing for measuring a level of contamination of the received washing water.
摘要:
The present invention relates to a catalyst for steam cracking of hydrocarbons, which steam cracks hydrocarbons to improve a yield of olefins such as ethylene and propylene, reduces produced coke, and has superior thermal stability at a high temperature. Particularly, the present invention provides a catalyst for steam cracking of hydrocarbons comprising potassium phosphate as a catalyst component, preparation thereof, and olefin preparation by steam cracking of hydrocarbons using the same.

A water guide of a dishwasher checks the flow of water draining from the dishwasher. The water guide includes a drain passage having one end communicating with an outer atmosphere and another end communicating with a sump for receiving washing water, at least part of the drain passage being routed via a point higher than a water level in the sump, and a valve assembly, disposed above the drain passage, for selectively introducing external air into the drain passage.
摘要:
Disclosed is a method for manufacturing a conductive organic thin film device. An air-bridge type of an upper electrode is formed over a lower electrode by using a sacrificial layer and then a gap having a thickness of several nano meter is formed in a part at which the upper electrode and the lower electrode intersect by removing the sacrificial layer. The conductive organic molecules are uniformly adsorbed between the upper electrode and the lower electrode of the nano gap. Adsorption extent of the conductive organic molecules is confirmed by observing a current flowing through the upper and lower electrodes when the conductive organic molecules are adsorbed. Thus, reproducibility of a manufacturing process is improved and mass production is facilitated by adoption of a standardized process.
