Abstract: Representative embodiments disclosed compress expressions so they utilize less physical storage. An expression is placed in a standard representation, such as an expression tree. The system utilizes one or more rules to identify portions of the expression that are likely to be common to other expressions. The common portions are extracted from the expression tree as a template and the remaining portions are hoisted from the expression as unique portions. If the template does not already reside in a cache, the template is stored in the cache. A cache reference is obtained for the template and combined with the unique portions to create a bundle that reduces storage requirements for the expression. The original expression is recovered by retrieving the template from the cache using the cache reference and placing the hoisted unique portions into their original locations in the template.

Abstract: An ingress forwarder receives the IP packet and strips off the entire packet header and replaces it with the simple flow header assigned by the controller, and looks up its flow-table to determine from which port to forward the packet. All other forwarders along the path up to the egress forwarder perform the forwarding action simply by inspecting the flow header. The egress forwarder, before forwarding to the egress port, replaces the flow header with the original layer-2/3/4 header. Doing so, the host behavior remains unchanged while the routing/forwarding within the cloud of SDN is performed based on only the flow header.

Abstract: A face tracking system generates a model for extracting a set of facial anchor points on a face within a portion of a face image based a multiple-level cascade of decision trees. The face tracking system identifies a mesh shape adjusted to an image of a face. For each decision tree, the face tracking system identifies an adjustment vector for the mesh shape relative to the image of the face. For each cascade level, the face tracking system combines the identified adjustment for each decision tree to determine a combined adjustment vector for the cascade level. The face tracking system modifies adjustment of the mesh shape to the face in the image based on the combined adjustment vector. The face tracking system reduces the model to a dictionary and atom weights using a learned dictionary. The model may be more easily transmitted to devices and stored on devices.

When the device finishes playing the first content collection, the device automatically begins playing a next content collection. Additional content collections generated from content submitted by other client devices can be received from the server computer system, with autoforward play of additional content collections continuing indefinitely.

Abstract: An IP router capable of isochronous switching of a packetized media stream. According to an example, the IP router parses the RTP header within an incoming IP datagram to extract the RTP time stamp, which provides a time value for a unique IP Flow. By inspecting the header, the IP router can switch the flow at the point in time that the RTP time stamp value changes, or matches a target value. In one aspect, the IP router looks for the change in the RTP time stamp value and performs the switch based on the detected change. In another aspect, the IP router performs the switch at a specified time stamp value that can be unique to a group of signals or based on a common “sync” value published to all the ports of the IP router.

Abstract: Standardized digital signature schemes (e.g., Rivest-Shamir-Adleman (RSA), Digital Signature Algorithm (DSA), Elliptical Curve Digital Signature Algorithm (EC-DSA), etc.) may be employed to prove authenticity of a message containing credentials.

Such techniques may allow proving entities to prove possession of valid credentials using standardized signature schemes without revealing those credentials directly to a verifying entity.
