Multipoint Control Unit

The presented tool is a fully virtualized videoconferencing MCU (Multipoint Control Unit) system using the standard SIP (Session Initiation Protocol). The proposed tool works in the cloud in a scalable way, with low deployment and maintenance costs. In addition, the proposed tool is more than an MCU, functioning as a universal framework for media forwarding.

Conferencing System

The purpose of this paper is to present advances in the Mconf web conferencing system to support transparent interoperability with room videoconferencing equipment (known as endpoints), Multipresence system, and Phone@RNP. The system can behave as SFU (Switching Forwarding Unit) or MCU (Multipoint Control Unit), making decisions about the best signal to send to each destination. The following main benefits can be cited: 1) Improving user interaction in the use of such systems, so that it simply enters the portal “Video Collaboration Service”, and the system make the necessary adaptations to obtain the best user experience; 2) Have a single MCU + SFU service, savings resources, as it concentrates programmers on the same code.

Multi Level

Providing highly secured access to restricted or private areas has become highly required these days, mainly due to terrorism threats. One method of security is no longer sufficient, hence the term and technology of a “multi-level” security system was developed by integrating more than one security procedure, on both hardware and software levels. This research provides a simple, cheap, easily achievable, yet highly secured multi-level security system to control access through doors. The system integrates IRIS scan authentication, innovative IRIS image encoding, encrypted of mobile communication, and multipoint Control Unit (MCU) Security as main procedures of security. The system’s novelty shows in the encoding and encryption of IRIS image data that is acquired by a mobile phone before it is sent to the authentication site, where it is decrypted by a cheap and fast MCU to retrieve the IRIS image that is fed into a Neural Network in order to grant authorization to the user.

Relationship Of

In a secondary control unit system, an accumulator changes the relationship of the pumps and motor from flow coupling to pressure coupling. This change creates several benefits, including energy conservation, increased stability and the ability to change the rotational direction of the hydraulic motor. The accumulator therefore plays an important role because it dominates the overall performance of the secondary control unit system. This paper studies the influence of accumulator volume and precharge gas pressure on the performance of a hydrostatic transmission system in a secondary unit control system. A small test rig of the secondary unit system was set up and a series of experimental studies were run. A mathematical model was derived for simulation purposes. The results reveal that making the volume of the accumulator and the precharge gas pressure as high as possible under permitted circumstances can decrease the fluctuation of working pressure, improve the dynamic performance of speed control and increase the recovery of energy.

"The telematics control unit system uses the functionalities of the A.D.A.S, E.C.M and A.B.S systems already existing on vehicles involving the hardware, software and mechanical components offered by them. The system is a service that provides the user with traffic safety and prior information on impediments to streamline the route. This paper presents how it is proposed that this system process the data and transmit it to a server that will then transmit this information to an interactive map.

Development Area

Nowadays, big expansion and innovation are emerging in all development area of technologies and technological devices. Probably industrial robots and manipulators belong to development too. Industrial robots and manipulators belong to progressive elements of automation. At present industrial robots and manipulators are used for manipulation with various types of objects. The proper using of gripper that creates important task in manipulation in term of object grasp and choose of right type of gripping jaws it is possible to manipulate with object that are fragile and soft. However at this time is very important check of the all time of the process assembly and disassembly in each time. The current information about automation process assembly or disassembly are evaluation to the control unit system.
