Publication number: 20140236505Abstract: A system and method of measuring power consumption in an appliance is provided. An electrical characteristic of a power signal, such as a voltage component and/or a current component, can be detected at the appliance. The detected electrical characteristic can be processed using a signal processor. During signal processing, the detected electrical characteristic can be shifted based on a predetermined threshold and converted to a digital signal. An electrical characteristic offset can be determined based on an average electrical characteristic value of a plurality of detected electrical characteristics. The difference between the electrical characteristic offset value and an instantaneously detected electrical characteristic value can be used to determine power consumption of the appliance.Type: ApplicationFiled: February 21, 2013Publication date: August 21, 2014Inventors: Sung Dong Yang, Dong Soo Shin, Dong Hun Lee, Young Han Choi, Jae Seok Noh, Eun Yeong An

Patent number: 8700621Abstract: An improved query suggestion system can allow a user to more effectively search for items they would like to purchase online. The present invention provides a computer-implemented method for generating query suggestions based on user-generated content. A user may begin an online shopping venture by entering a keyword into the search function on a shopping website or other search engine interface. The search engine can launch a search of user generated content on the Internet, such as product related blogs, product reviews, or question-and-answer articles. The search engine can extract frequently repeated bigrams from the content. The search engine may combine the bigrams to generate candidate composite words and select a final query suggestion list from the candidate words. The query suggestion list is displayed to the user in the search interface. The user may select one of the suggested queries if it more accurately defines his search.Type: GrantFiled: March 20, 2012Date of Patent: April 15, 2014Assignee: Google Inc.Inventors: Yung Choi, Eun Yeong Ahn

Patent number: 8468872Abstract: A novel method of manufacturing a hydrogen sensor is disclosed. The method includes the steps of forming a thin film made of a transition metal or an alloy thereof on a surface of an elastic substrate, and forming a plurality of nanogaps in the thin film formed on the surface of the elastic substrate by applying a tensile force to the elastic substrate. The nanogaps are formed as the thin film is stretched in a direction in which the tensile force acts while being contracted in a direction perpendicular to the direction in which the tensile force acts when the tensile force is applied, and is contracted again in the direction in which the tensile force is released while being stretched again in the direction perpendicular to the direction in which the tensile force is released when the tensile force is released.Type: GrantFiled: December 3, 2010Date of Patent: June 25, 2013Assignee: Industry-Academic Cooperation Foundation, Yonsei UniversityInventors: Woo Young Lee, Jun Min Lee, Eun Yeong Lee
