摘要： A videoconferencing conferee may be provided with feedback on his or her location relative a local video camera by altering how remote videoconference video is displayed on a local videoconference display viewed by the conferee. The conferee's location may be tracked and the displayed remote video may be altered in accordance to the changing location of the conferee. The remote video may appear to move in directions mirroring movement of the conferee. This effect may be achieved by modeling the remote video as offset and behind a virtual portal corresponding to the display. The remote video may be displayed according to a view of the remote video through the virtual portal. As the conferee's position changes, the view through the portal changes, and the remote video changes accordingly.

摘要： A method for authenticating and negotiating security parameters among two or more network devices is disclosed. The method has a plurality of modes including a plurality of messages exchanged between the two or more network devices. In a main mode, the two or more network devices establish a secure channel and select security parameters to be used during a quick mode and a user mode. In the quick mode, the two or more computers derive a set of keys to secure data sent according to a security protocol. The optional user mode provides a means of authenticating one or more users associated with the two or more network devices. A portion of the quick mode is conducted during the main mode thereby minimizing the plurality of messages that need to be exchanged between the initiator and the responder.

摘要： Systems are disclosed that provide improved transfer speed of video data from a video capture device to a computing device using multiple video feeds respectively comprising different resolutions. A high-resolution image sensor is used to convert light images into a high-resolution video data stream. A down sampler converts the high-resolution video data stream to a low-resolution video data stream, so that both a low-resolution data stream and a high-resolution data stream are available. While the low resolution-data stream can be sent to the computing device, a digital signal processor (DSP) processes the high-resolution video data stream in accordance with an input control signal that is comprised of desired high-resolution video stream parameters derived from the low-resolution video data stream.

摘要： A method to negotiate computer settings in advance is presented. A prediction is made to determine if the computer setting will be needed, and if needed, whether a value outside of a normal range of values will be needed. A value for the computer setting that is outside of the normal range of values is determined and the value is set to the outside value. A value within the normal range of values is used if it was predicted that there is no need for a value outside of the normal range of values.

摘要： Disclosed is a method for slowing down the spread of viruses by limiting the number of Transmission Control Protocol (“TCP”) connection attempts to arbitrary Internet Protocol (“IP”) addresses that can be in progress at any given time—a common method employed by viruses to spread to other hosts from an infected host. This is achieved by setting a small limit on the number of connection attempt requests that can be in progress at any given time and can be implemented regardless of whether anti-virus software is installed on the system.

摘要： A system and method for defeating SYN attacks are provided. When the number of packets received by a server is above the capacity of the server, the server assumes that a SYN attack is in progress. The server randomly drops SYN packets without processing them. The percentage of SYN packets dropped is increased while the load on the server exceeds capacity, and decreased while the load on the server does not exceed capacity. Under attack conditions, a percentage of TCP connections are still maintained.
摘要翻译：提供了一种用于击败SYN攻击的系统和方法。当服务器接收的数据包数量高于服务器的容量时，服务器假定正在进行SYN攻击。服务器随机丢弃SYN数据包而不进行处理。当服务器上的负载超过容量时，丢弃的SYN数据包的百分比就会增加，服务器上的负载不会超过容量。在攻击条件下，仍然维持一定百分比的TCP连接。
