Abstract: In an internal network monitoring method for monitoring an internal network, a specified network packet, which is scheduled to be transmitted via a specified path, is inspected. A packet characteristic is extracted from a data link layer of the specified network packet. The specified network packet is directly transmitted via the specified path if the packet characteristic does not comply with a preset condition. The specified network packet is redirected to be transmitted via another path different from the specified path or mirroring the specified network packet to create a mirror packet if the packet characteristic complies with the preset condition.

Abstract: A wireless network device includes an antenna array and a lobe interleaver. The antenna array includes a plurality of antenna elements with different squint angles. The lobe interleaver is coupled to the antenna elements and has a plurality of output lobe ports. The lobe interleaver divides and interleaves the radio signal of the antenna array with the same phase and the same power to generate a plurality of lobes with different squint angles. The number of lobes is twice the number of antenna elements.

Abstract: A method and an apparatus for automatically adjusting monitoring frames based on image variation are disclosed. According to the present invention, a changed block judgment device and a regional image output device are added to an image capturing device. When the image is moving or changing, the corresponding changed blocks are located automatically, and then a focus block is determined. Afterwards, the image within the focus block is output to an image receiving device after the resolution thereof has been adjusted. Therefore, the purpose of automatically adjusting monitoring frame is achieved.

Abstract: A method and an apparatus for adjusting output images are provided. In the method, a target area is selected from the original frame received by an image receiving device and an image capturing device is controlled to capture the image within the target area. Hence, users can change angles to view images within different target areas without rotating the lens of the video device. In addition, the image resolution is adjusted automatically according to the screen resolution of the image receiving device or the resolution corresponding to the network bandwidth. Therefore, the defects in the prior art that mechanical operation is easily damaged and the manufacturing cost is high are eliminated. The purpose of effectively enhancing image resolution is also achieved.
