Abstract: An exemplary system and method are disclosed for a handheld or hand-enclosed instrument configured with ultra-wideband localization using unidirectional messaging protocol based on time difference of arrival (TDoA) measurements that can be used as inputs, in a realtime control loop, to a software application that uses the handheld or hand-enclosed instrument as an input user interface. The handheld or hand-enclosed instrument can be readily employed for UI in large work areas (e.g., 2D), such as a whiteboard or wallboard, with sub-millimeter resolution and sub-millisecond latency. The handheld or hand-enclosed instrument can be readily employed in a UI device for non-conforming 3D workspace such as a sculpting instrument, in hand-enclosed game interface, as a remote medical instrument, among others described herein.

Abstract: An exemplary system and method are disclosed for capturing visual body signals using distance measurements among different parts of the body and for providing classification for them. The exemplary system and method can be employed to generate the classification and provide a second source of communication of the classification to supplement the visual cues provided by such body motion or positioning.

Abstract: In one example, a processing system including at least one processor obtains a transport control protocol flow associated with a video session that streams a video from a server to a client. The transport control protocol flow comprises a plurality encrypted packets exchanged between the server and the client. The processing system then reconstructs a hypertext transfer protocol transaction that is part of the streaming video session. The reconstructing is performed without decrypting the plurality of encrypted packets.

Abstract: A network may include a plurality of nodes forming a first layer and a sub-set of the plurality of nodes forming a second layer. The first layer may follow a first routing objective in routing traffic, and the second layer may develop constraints based on the first routing objective and follow a second routing objective within the developed constraints in routing traffic. In another network, the second layer may follow a second routing objective in routing traffic, and the first layer may develop constraints based on the second routing objective and follow a first routing objective within the developed constraints in routing traffic.

Abstract: The present invention provides a “data centric” approach to updating databases on computer systems of an intermittently connected database system. In this approach, the storage and processing complexity of the database server are de-coupled from the number of clients to be supported, thereby, improving the scalability of the server. Instead of focusing on the data required by individual clients, this method tracks changes to data subsets pertaining to groups of clients. Thus, the server need only track and record changes to these subsets of data, instead of tracking changes for individual clients. Clients download the subsets, which contain the data relevant to the group, and merges data or deletes superfluous data from the subsets. Since the server is tracking a limited set of data subsets related to groups of clients instead of the actual number of the clients, the overall scalability of the system is increased.
