The Multi-Link Aircraft Cellular System makes use of multiple physically separated antennas mounted on the aircraft, as well as the use of additional optional signal isolation and optimization techniques to improve the call handling capacity of the Air-To-Ground cellular communications network. These additional techniques can include polarization domain and ground antenna pattern shaping (in azimuth, in elevation, or in both planes). Further, if code domain separation is added, dramatic increases in capacity are realized. Thus, the Air-To-Ground cellular communications network can increase its capacity on a per aircraft basis by sharing its traffic load among more than one cell or sector and by making use of multiple physically separated antennas mounted on the aircraft, as well as the use of additional optional signal isolation and optimization techniques.

Without changing an existing network and terminals, means for preventing improper use of the network is introduced at low costs. An address management server having a topology database of Layer 2 devices (hub, switch, and wireless station in the case of Ethernet) that configure an intranet is used. Within the server, with respect to each Layer 2 device, an address / port number correspondence acquisition means and a packet filtering specification means are stored. The address management server, according to topology information, recursively calls the address / port number correspondence acquisition means of each Layer 2 device from the upstream of the network, thereby obtaining a Layer 2 device accommodating a given Layer 2 address and its port number. By recursively calling the packet filtering specification means from the Layer 2 device in the upstream direction of the network, the Layer 2 device obtained above and its port number are filtered in a Layer device nearest to the terminal.

A knee brace for rehabilitation provides a stable support for an injured knee using a four-crank mechanism. Positioning pins are used to fix limiting blocks pivoted to the upper and lower braces. It limits the moving range of the crank between the upper and lower braces, restricting the moving angles of the upper and lower braces. Besides, the buffer pads are covered at the pivotal axes of the upper and lower braces in order to alleviate the collision between joint surfaces during the motion of injured knee. Such a mechanism protects the rehabilitating knee joint. The disclosed structure can solve the failure problem of the knee brace for rehabilitation due to a loose pin in the prior art. The counterforce to injured knee from the performance of knee brace reduced for rehabilitation can prevent the user's knee joint from further injuries.
