20090285467 | METHOD FOR ASSESSING BONE STATUS - A method for assessing bone status is disclosed. The method for assessing bone status comprises steps of: obtaining a chest radiograph, recognizing a target bone on the chest radiograph by active shape models, detecting edges of a cortical bone of the target bone by intelligent scissors, and calculating a parameter of bone status through the cortical bone. The present invention increases the diagnosis value of the chest radiography and provides a simple, economic, rapid and reliable assessment of bone status. | 11-19-2009 |

20140091911 | MOVING CARRIER SIGNAL TRANSMISSION METHOD AND DEVICE THEREOF - A moving carrier signal transmission method and a signal transmission device using the same are provided. A main moving carrier acquires an identification code of an ambient moving carrier. The main moving carrier adds an identification code of the main moving carrier and the identification code of the ambient moving carrier in a data request and then sends out the data request to the ambient moving carrier according to the identification code of the ambient moving carrier. When the ambient moving carrier obtains the data request, the ambient moving carrier adds the identification code of the main moving carrier in a moving carrier list and transmits the moving carrier list to the main moving carrier. | 04-03-2014 |

20140140207 | SYSTEM AND METHOD FOR REDUCING LOADS OF MOBILITY MANAGEMENT ENTITY (MME) IN CORE NETWORKS - The present invention provides a system and method for reducing loads of a mobility management entity in core networks. An object sending a connection-request message asking for network access to a base station through a wireless network; the base station receiving the connection-request message and sending it to core networks through a network; a mobility management entity (MME) in the core network receive the connection-request message. If the core network is busy and refuses to interconnect with the object, MME calculating according to a management rule a back-off time; MME transmitting a response message including the back-off time to the object through the base station, and the object sending out a connection-request message again after the back-off time has elapsed according to the response message. | 05-22-2014 |

20150103968 | Computed Tomography (CT) Image Reconstruction Method - The present invention discloses a computed tomography (CT) image reconstruction method using two-dimensional images at different angles as well as a two-dimensional virtual matrix on a basis of spherical space, to process projection, comparison, and correction. Thus, it can obtain the tomography within predetermined difference value to reduce computational and storage space. Matching the parameters of energy source and image capturing can further shorten energy radiation on an object's (i.e. a human body) exposure time, in order to reduce radiation effects of energy sources (i.e. as X-rays) of the object (i.e. as a human body). | 04-16-2015 |

20120065829 | Wall-following Moving Device - A wall-following moving device consists of a base; a determining drive unit; multiple collision sensing units; two signal transceiver units arranged at the same lateral side of the base parallel to the moving direction of the base for synchronously transmitting and receiving specific signals, and being electrically connected to the determining drive unit; and a moving element mounted to the base and controlled by the determining drive unit to perform various movements. The determining drive unit compares two reflected signals from a wall received separately by two signal transceiver units, and uses the intensity difference of the signals as a basis to control the moving element to orientate the robot parallel to the wall. By an intricate coordination of the collision sensing units, two signal transceiver units, determining drive unit, and the moving element, the distance between the robot and a wall can be precisely determined and controlled. | 03-15-2012 |
20120066846 | Structural Improvement For Robotic Cleaner - The present invention is an improved structure for robotic cleaner primarily comprising of a chassis with plurality of spherical casters fixed to the periphery of bottom deck, a dust collector mounted on the chassis, a lifting actuation mechanism mounted on the chassis that includes a lifting power supply at least to drive two parallel & extendable first swing arms and two parallel & extending second swing arms through a relevant linking device, a first gear train and a second gear train that can pivotally rotate in reverse direction, a drive wheel mounted at the moveable end of the two parallel & extending first swing arms each, a driven wheel mounted at the moveable end of the two parallel & extending second swing arms each, plural advancing power supplies mounted at the middle section of the first swing arms. | 03-22-2012 |
