摘要:
Disclosed herein are an apparatus and method for generating traffic information. The apparatus includes a first information collection unit, a second information collection unit, a comparison and analysis unit, and a computation unit. The first information collection unit collects first sensed data, including first reference sampled data and a plurality of pieces of first surrounding sampled data from a first sensor unit. The second information collection unit collects second sensed data, including second reference sampled data and a plurality of pieces of second surrounding sampled data from a second sensor unit. The comparison and analysis unit determines similarity between the first sensed data and the second sensed data, extracts a first time from the first sensed data, and extracts a second time from the second sensed data. The computation unit calculates the vehicle's average speed.

A thin film transistor (TFT) and a method of fabricating the same are disclosed. The TFT includes a substrate, a gate electrode disposed over the substrate, a gate insulating layer disposed over the gate electrode, a semiconductor layer disposed over the gate insulating layer and including a polycrystalline silicon (poly-Si) layer, an ohmic contact layer disposed over a predetermined region of the semiconductor layer, an insulating interlayer disposed over substantially an entire surface of the substrate including the ohmic contact layer, and source and drain electrodes electrically connected to the ohmic contact layer through contact holes formed in the interlayer insulating layer. A barrier layer is interposed between the semiconductor layer and the ohmic contact layer. Thus, when an off-current of a bottom-gate-type TFT is controlled, degradation of characteristics due to a leakage current may be prevented using a simple process.

The present invention relates to an RFID application interface method and a system thereof. In the present invention, an RFID middleware system changes a control request input from a user or an RFID application system according to a communication protocol of an RFID device to be controlled, and sends it to the RFID device. Also, when the user or the RFID application system inputs a data process policy that is common to various RFID devices of a logical RFID device group, the RFID middleware system generates data process rules that are suitable for communication capability and data processing capability of each RFID device based on the data process policy and provides an interface that allows processing of data by a corresponding RFID device. In addition, the RFID middle system defines a procedural flow of at least one of services and at least one of tasks that constitute an RFID business process and provides an interface to support interconnection and cooperation of services that are included in the RFID business process.
