  • Patent number: 10068091
    Abstract: Systems and methods for malware containment on connection is provided. In exemplary embodiments, a malware containment method is described that performs a number of operations. The method involves redirecting network data received over a communication network to a virtual machine. The virtual machine is configured to simulate functionality of a digital device. Furthermore, the method involves analyzing of the redirected network data that including analyzing a response of the virtual machine to processing of the network data within the virtual machine to identify a malware attack. Thereafter, the method involves continuing to redirect the network data for processing by the virtual machine until expiration of a predetermined period of time without detection of malware, or continuing to redirect the network data for processing by the virtual machine beyond the predetermined period of time when malware is detected.

  • Patent number: 9864180
    Abstract: An asymmetric curved-surface prismatic image display optical system includes a first prism and second and third prisms respectively arranged in front of and behind the first prism. The first prism includes a light-exiting planar surface that is at an eye-adjacent side and is opposite to a light-entering planar surface of the second prism with an air gap therebetween and may serve as a reference for inspection of a free-form curved surface. The second prism has a light-exiting planar surface at the eye-adjacent side and parallel to a side planar surface of the third prism to allow an external-world image to be seen more clearly. Light from an image displaying panel first enters the first prism and is subjected to total internal reflection by the light-exiting planar surface toward the reflective curved surface to be reflected and re-directed to transmit through the second prism for image formation on a retina.

  • Patent number: 9755984
    Abstract: Methods, apparatuses and systems directed to an aggregate bandwidth utilization control scheme including fair share bandwidth allocation and dynamic allocation of bandwidth in response to detected traffic utilization. In one implementation, the present invention includes a weighted, fair share aggregate bandwidth allocation mechanism that dynamically responds to observed bandwidth utilization to provide unutilized or excess bandwidth to flows and partitions that require it. In another implementation, the present invention features a weighted fair share allocation scheme for hierarchical partition configurations. In other implementations, the present invention provides a per-flow target rate assignment mechanism that prevents spiraling decline of data flow rates.

  • Patent number: 9197664
    Abstract: Systems and methods for malware containment on connection is provided. In exemplary embodiments, digital devices are quarantined for a predetermined period of time upon connection to the communication network. When a digital device is quarantined, all network data transmitted by the digital device is temporarily directed to a controller which then analyzes the network data to identify unauthorized activity and/or malware within the newly connected digital device. An exemplary method to contain malware comprises detecting a digital device upon connection with a communication network, temporarily redirecting network data from the digital device, and analyzing the network data to identify malware within the digital device.
