29 Apr 2002TL;DR: Sync-VPN as discussed by the authors provides a network support mechanism, called Sync-VPN, that is transparent to real-time, multi-user distributed applications, such as online multi-player games in which the order of player actions is critical to the outcome.
Abstract: The present invention provides a network support mechanism, called Sync-VPN, that is transparent to real-time, multi-user distributed applications, such as online multi-player games in which the order of player actions is critical to the outcome. The invention uses a client/server application model, where a server coordinates state updates based on action messages sent by clients. The invention builds on bandwidth-quaranteed VPN service to ensure predictable packet delay and loss characteristics, thereby providing predictable packet service, state update fairness, and player action fairness. A Sync-out mechanism synchronizes delivery of state updates to all players enabling them to react to the same update fairly. A Sync-in mechanism processes action messages from all players in a fair order based on real-time occurrence. Sync-VPN employs a round-trip time estimation algorithm essential to message latency estimation in the Sync-out and Sync-in mechanisms.

08 Oct 2013TL;DR: This paper introduces uTrack, a technique to convert the thumb and fingers into a 3D input system using magnetic field (MF) sensing, and calculates the magnet's 3D position and tilt angle directly from the sensor readings.
Abstract: While much progress has been made in wearable computing in recent years, input techniques remain a key challenge. In this paper, we introduce uTrack, a technique to convert the thumb and fingers into a 3D input system using magnetic field (MF) sensing. A user wears a pair of magnetometers on the back of their fingers and a permanent magnet affixed to the back of the thumb. By moving the thumb across the fingers, we obtain a continuous input stream that can be used for 3D pointing. Specifically, our novel algorithm calculates the magnet's 3D position and tilt angle directly from the sensor readings. We evaluated uTrack as an input device, showing an average tracking accuracy of 4.84 mm in 3D space - sufficient for subtle interaction. We also demonstrate a real-time prototype and example applications allowing users to interact with the computer using 3D finger input.

19 Nov 2001TL;DR: In this article, a telecommunication system communication to and/or from a user equipment is carried on a user plane and messages supporting the communication are carried on the control plane, and information supporting provision of information about the location of the user equipment are also arranged to be carried on either the user plane to and from the user devices.
Abstract: In a telecommunication system communication to and/or from a user equipment is carried on a user plane and messages supporting the communication are carried on a control plane. Information supporting provision of information about the location of the user equipment is also arranged to be carried on the user plane to and/or from the user equipment.

TL;DR: The design flow is utilized in the integration of state-of-the-art technology approaches, including a wireless terminal architecture, a network-on-chip, and multiprocessing utilizing RTOS in a SoC.
Abstract: This paper describes a complete design flow for multiprocessor systems-on-chips (SoCs) covering the design phases from system-level modeling to FPGA prototyping. The design of complex heterogeneous systems is enabled by raising the abstraction level and providing several system-level design automation tools. The system is modeled in a UML design environment following a new UML profile that specifies the practices for orthogonal application and architecture modeling. The design flow tools are governed in a single framework that combines the subtools into a seamless flow and visualizes the design process. Novel features also include an automated architecture exploration based on the system models in UML, as well as the automatic back and forward annotation of information in the design flow. The architecture exploration is based on the global optimization of systems that are composed of subsystems, which are then locally optimized for their particular purposes. As a result, the design flow produces an optimized component allocation, task mapping, and scheduling for the described application. In addition, it implements the entire system for FPGA prototyping board. As a case study, the design flow is utilized in the integration of state-of-the-art technology approaches, including a wireless terminal architecture, a network-on-chip, and multiprocessing utilizing RTOS in a SoC. In this study, a central part of a WLAN terminal is modeled, verified, optimized, and prototyped with the presented framework.
