摘要:
A method and system for providing a Network-based User Interface (NUI) is provided. The method for providing the NUI includes: selecting one from among devices connected to a network; acquiring a UI regarding the selected device through the network; and interacting with the device by using the acquired UI. Accordingly, the user terminal can acquire the UI regarding the device connected to the network through the network and interact with the device, so that the user can easily manipulate the device at a remote distance and can easily grasp the statue of the device.

A method for controlling a multi-sink/multi-path routing sensor network and a sensor network system using the same are provided. The method for controlling the sensor network includes generating, at a sensor node, sensing data; transmitting, at the sensor node, the sensing data to a plurality of sink nodes; and forwarding, at the sink nodes receiving the sensing data from the sensor node, the sensing data to a gateway. Hence, it is possible to satisfy the reliability required in the safety-critical system with the minimum traffic. Both of the two conflicting requirements which are the reliability enhancement of the sensor network and the minimization of the network traffic in the repeated data transmission, can be satisfied adequately.

Provided is a beacon scheduling method based on a distributed address assignment scheme that schedules a beacon and minimizes data delay using non-collision of addresses in a network, such as a ZigBee network, that provides a distributed address system. In the method, a time offset Tn between beacon reception from a parent device and beacon transmission of a device in a wireless network system having a tree structure may be obtained from Tn=SD×(1+On×Bd) according to an address of the device determined by a distributed address assignment mechanism to create a beacon transmission schedule, where SD denotes a super-frame duration, On denotes a value for determining which child among sibling devices in the network the device corresponds to, and Bd denotes a maximum number of router devices that a sub-network having a depth d in a tree can have.

An fusing apparatus for correcting process variation is provided. The fusing apparatus for correcting the process variation of the semiconductor device includes a fusing part including a fusing resistor fused by a current penetrating; a current driving transistor for fusing the fusing resistor by driving a fusing current according to a fusing enable signal applied; a current path part for building a current path by connecting to the fusing part, and controlling a first node voltage according to a fusing state of the fusing resistor; and a latch part for latching a second node signal inversely amplified from the first node voltage, and outputting the latch value when a power-on reset part operates in a normal mode. Using the fusing cell, the test time can be reduced and the current consumption can be greatly decreased in the fusing process.
