摘要： A time check method and a base station are provided. The base station receives an authentication interaction message sent by an authentication interaction device; extracts time information in the authentication interaction message; and uses the time information to check local time. Before an Internet Key Exchange (IKE) connection is set up between the base station and a security gateway, relatively accurate time is obtained from an external authentication interaction device and is used for aligning the local time. Therefore, the cost of installing a clock component and a battery is saved, the time on the base station is trustworthy, and the security gateway is authenticated securely.

摘要： The present patent application relates to a polarization interference optical interleaver, which includes a first port to transmit the first optical signal through the first optical path, a second port to transmit the second optical signal and a third port to transmit the third optical signal. The first optical signal passes through the first optical path and splits into the second optical signal and the third optical signal by the first and the second light splitting/combining crystals and the interference crystal group. The interference crystal group is located between the first and the second light splitting/combining crystals. The second optical signal and the third optical signal are received and reflected by a reflecting mirror. Then the second optical signal and the third optical signal output through the second port and the third port respectively. The second optical signal reflected by the reflecting mirror transmits along the first optical path of the first optical signal and passes through the interference crystal group, then walks off the first optical path by light walk-off device and outputs through the second port. The third optical signal reflected by the reflecting mirror transmits along the second optical path and passes through the interference crystal group, then outputs through the third port. There are only four beams in the interference crystal group of the present patent application. So the volume of the interference crystal group is minimized and the cost is reduced.

摘要： Exemplary systems and methods segment a foreground from a background image in a video sequence. In one implementation, a system refines a segmentation boundary between the foreground and the background image by attenuating background contrast while preserving contrast of the segmentation boundary itself, providing an accurate background cut of live video in real time. A substitute background may then be merged with the segmented foreground within the live video. The system can apply an adaptive background color mixture model to improve segmentation of foreground from background under various background changes, such as camera movement, illumination change, and movement of small objects in the background.
