20120007707 | NON-CONDUCTIVE LID FOR TRANSFORMERS - The present invention is an electrically non-conductive transformer lid that may replace the top of the housing of a transformer or be attached to the housing of a transformer. The lid may isolate an animal that is in contact with the lid from the ground grid, even if the animal attempts to make contact with the energized primary conductor or other apparatuses. The present invention thereby prevents electric current from flowing through the animal's body to the ground and prevents outages or electric faults from occurring. It may be attachable to a variety of known types of transformers, including pole-mounted distribution transformers. The means of attaching and removing the lid may be performed by a single person. The lid may be shaped to prevent moisture or other particulates from entering the transformer and thereby further protect the function of the transformer. | 01-12-2012 |

20100145514 | APPARATUS AND METHOD FOR CONTROLLING MULTI-ROBOT LINKED IN VIRTUAL SPACE - The present invention relates to an apparatus and method for controlling a multi-robot linked in virtual space, and when an event is generated in accordance with information change in virtual space including the web as well as the environmental change around a robot, the present invention controls individual behavior or collective behavior or corresponding robots by transmitting behavior data corresponding to the generated event to a plurality of robots. According to the present invention, by making a robot perform specific behavior in response to not only changes in the real environment, but information changes in the web, it is possible to arouse the user's interest or the developer's originality while removing due to complicity of the real environment, which is a problem limiting application of the robot, or dynamic response. | 06-10-2010 |

20110044596 | MULTI-MODE BENDING-RESISTANT FIBER AND PRODUCTION METHOD THEREOF - A multimode fiber including a core and a cladding. The core has a radius (R1) of 24-26 μm, the refractive index profile thereof is a parabola, and the maximum relative refractive index difference (Δ1) is 0.9-1.1%. The cladding surrounds the core and includes from inside to outside an inner cladding, a middle cladding, and an outer cladding; a radius (R2) of the inner cladding is 1.04-1.6 times that of the core, and a relative refractive index difference (Δ2) thereof is −0.01-0.01%; the middle cladding is a graded refractive index cladding whose radius (R3) is 1.06-1.8 times that of the core, and a relative refractive index difference thereof is decreased from Δ2 to Δ4; and a radius (R4) of the outer cladding is 2.38-2.63 times that of the core, and a relative refractive index difference (Δ4) thereof is between −0.20 and −0.40%. The invention reduces the additional bending loss of the fiber, improves the bending resistance and mechanical properties, basically eliminates the internal stress, and ensures the service life even working for a long term under the condition of low radius. The method for producing the fiber is simple, effective, and suitable for mass production. | 02-24-2011 |

20140185996 | BENDING INSENSITIVE SINGLE MODE OPTICAL FIBER - In one aspect of the invention, the bend insensitive single-mode optical fiber includes a core layer and cladding layers having an inner cladding layer, a trench cladding layer and an outer cladding layer sequentially formed surrounding the core layer from inside to outside. For the core layer, the diameter is 7-7.9 μm, and the relative refractive index difference Δ | 07-03-2014 |
