摘要:
Provided are a system and a method for reducing a communication load of an apparatus for tracking a moving object. The system includes: an estimated necessary time calculating unit receiving a current location and an arrival location of the moving object from a terminal included in the moving object, calculating estimated necessary time for the moving object to reach the arrival location, and transmitting the estimated necessary time to the terminal; and a communication path on-off controlling unit activating a communication path for the terminal to receive the estimated necessary time from the estimated necessary time calculating unit, and inactivating the communication path when the terminal receives the estimated necessary time through the communication path.

An isolation layer structure includes first to fourth oxide layer patterns. The first and third oxide layer patterns are sequentially formed in a first trench defined by a first recessed top surface of a substrate and sidewalls of gate structures on the substrate in a first region. The first trench has a first width, and the first and third oxide layer patterns have no void therein. The second and fourth oxide layer patterns are sequentially formed in a second trench defined by a second recessed top surface of the substrate and sidewalls of gate structures on the substrate in a second region. The second trench has a second width larger than the first width, and the fourth oxide layer pattern has a void therein.

A method for creating a grid-based tree in a multiple sensor network includes: dividing an entire area in which a base station node and a plurality of sensor nodes are disposed into grid areas; assigning a grid ID to each of the grid areas; setting, sequentially from the base station node to each of the sensor node, level information, candidate child nodes and candidate parent nodes; storing a grid ID of a grid area in which the respective nodes locate; selecting, for the respective sensor nodes, a parent node based on the grid ID, the level information, and the candidate parent nodes; and calculating, for the respective nodes, minimum bounding rectangles each of which includes a child node of corresponding node and nodes descended from the child node. The grid-based tree is calculated by using the minimum bounding rectangles.

摘要:
A dielectric layer is formed by depositing a first dielectric layer above a semiconductor substrate including recessed regions, etching the first dielectric layer to remove any voids and to lower the aspect ratio of the recessed regions, and depositing a second dielectric layer on the first dielectric layer in the recessed regions. The method is particularly useful when the aspect ratios are high for recessed regions formed between patterns.
