Abstract: A method of detecting an object using a structured light and a robot using the same are disclosed. The method of detecting a floor object using a structured light includes measuring a height difference of a position onto which a specified structured light is projected with a reference position, and detecting the floor object using the measured height difference.

Abstract: The present invention relates to copper nano-particles having controlled particle size, high monodispersity, and oxidation stability, a method of preparing the copper nano-particles, and a method of forming a copper coating film using the copper nano-particles. The present invention provides a method of preparing copper nano-particles, comprising mixing a copper salt solution with a mixture of a reducing agent and a solvent; where the copper salt solution is added to the mixture at a temperature of 300° C. or less so that the copper salt solution can react with the mixture. It is thus possible to obtain copper nano-particles with controlled particle size and monodispersity by inducing uniform nucleation and nucleus growth through control of the reaction rate and/or the amount of copper ions during synthesis of the copper nano-particles.

Abstract: The present invention relates to monoclonal antibodies specifically binding to a membrane antigen of human mesenchymal stem cells, hybridoma cell lines producing the same, and methods for identifying or isolating human mesenchymal stem cells using the same. The monoclonal antibodies of this invention exhibit excellent specificity to human mesenchymal stem cells, inter alia, bone marrow-derived human mesenchymal stem cells, so that it allows for the identification and isolation of human mesenchymal stem cells with much higher specificity.

Abstract: A taximeter and method for calculating a cap fare using a navigation system is provided. The taximeter includes a GPS (global positioning system) module having a speed sensor to measure a speed, and receiving position information and absolute time information, calculating a self position, and outputting the calculated position, the time information, and the speed; a map database for storing map data; an input unit for generating a fare calculation start command, a fare calculation end command, and character data; a controller for mapping the calculated position to the map data, counting a time based on the time information, and accumulating a cap fare based on the counted time and the speed until receipt of the fare calculation end command; and a display unit for displaying the accumulated cap fare.

Abstract: A vestigial side band (VSB) synchronization (sync) signal detection circuit and method of generating a VSB sync signal is described. The circuit may include means for generating a first control signal related to sync signal generation, based on receipt of a selected one of an input first data signal and input second data signal, and means for generating a position signal containing information regarding positions of a next field sync and segment sync signals. The circuit may also include a correlator for generating a sign signal to determine a sign of the field sync signal, and a generator for generating a plurality of distinct types of sync signals based on the control signal, position signal and sign signal.
