This paper shows the development of remote control system for manipulators which consists of PHANToM Device as a master, Samsung FARA robot as a slave and TCP/IP based LAN for their Communication. This work includes the motion mapping between the master and the slave, Generation of virtual viscosity force preventing operator s unwilled action and 3D remote control simulators for the stable operation of the remote control system, etc. The remote control implementation has been performed and the results shows that the developed system can allow the operator to effectively control the manipulator.

In this paper, we describe a remote surveillance system to monitor the states of remote processes through Internet on Web browser The images captured from multiple remote cameras are transferred to data server exploiting RTP (Real-time Transport Protocol) and displayed up to 4 channels simultaneously. The angle of cameras is moved vertically an horizontally through RS-232C communication line by motor control board e벼ipped with AT90S2313 CPU.

We report a rare case of remote cerebellar hemorrhage after intradural disc surgery at the L1-2 level. Two days after the spine surgery, patient complained unexpected headache, dizziness, nausea and vomiting. From the urgently conducted brain CT, it was reported that the patient had cerebellar hemorrhage. Occipital craniotomy and hematoma evacuation was performed, and hemorrhagic lesion on the right cerebellum was effectively removed. After occipital craniotomy, the patient showed signs of improvement on headache, dizziness, nausea and vomiting. He was able to leave the hospital after two weeks of initial operation without any neurological deficit. Remote cerebellar hemorrhage following spinal surgery is extremely rare, but may occur from dural damage of spinal surgery, accompanied with cerebrospinal fluid leakage. Early diagnosis is particularly important for the optimal treatment of remote cerebellar hemorrhage.

This paper suggests remote injection system and explains the design of the system and means of implementation. Remote injection system means a system delivering the precise injection prescribed to the patient in the ward through input into the remote server using TCP/IP protocol. The system has been planned in detail. The syringe has been designed to be linked with the Ringer's rubber tube and the independently developed syringe-module is to be used in order to ensure precise and accurate delivery of the injected medication. In development stage of embedded software, object-oriented planning method has been chosen.

In this paper, wireless remote controller for welderss are implemented using RF communication. It can be used for general welding power sources. Sometimes, wireless remote controllers for welders are needed because welding torches are far away from welding sources in the case of big ship-building or big tank constructions. In order to use the wireless remote controllers, digital cpu-based welding systems are essential for digital interfaces. But, in this paper, using digital resistors makes wireless remote controllers be easily applied to digital or analog welders. To demonstrate the practical significance of our results, some experimental results are presented.

In this paper, we propose a double network control approach for linear systems. Generally, there are two network control system structures: the direct structure and the hierarchical structure. Here, the hierarchical structure consists of a main controller and a remote controller. The network delay of the structure only appears in the closed loop between the main controller and the remote system. However, the delay can exist between the remote controller and the actuator. Therefore, we design the double network system with delays between the main controller and the remote system, and the remote controller and the actuator. Finally, we carry out simulations on the linear system to illustrate the effectiveness of the proposed control method.

In the ubiquitous computing environment, a ubiquitous vehicle will be a communication node in the vehicular network as well as the means of ground transportation. It will make humans and vehicles seamlessly and remotely connected. Especially, one of the prominent services in the ubiquitous vehicle is the vehicle remote operation. However, mutual-collaboration with the in-vehicle communication network, the vehicle-to-vehicle communication network and the vehicle-to-roadside communication network is required to provide vehicle remote operation services. In this paper, an Internet-based human-vehicle interfaces and a network architecture is presented to provide remote vehicle control and diagnosis services. The performance of the proposed system is evaluated through a design and implementation in terms of the round trip time taken to get a vehicle remote operation service.

In this paper, we propose remote navigation control for intelligent robot using particle swarm optimization(PSO). The proposed system consists of interfaces for intelligent robot navigation and user interface in order to control the intelligent robot remotely. And communication interfaces using TCP/IP socket is used. To do this, we first design the fuzzy navigation controller based on expert's knowledge for intelligent robot navigation. At this time, we use the PSO algorithm in order to identify the membership functions of fuzzy control rules. And then, we propose the remote system in order to navigate the robot remotely. Finally, we show the effectiveness and feasibility of the developed controller and remote system through some experiments.

Recently because of development of remote network technology, users are able to access the network freely without constraints of time and space. As users are getting more frequent to access the remote server in a computing environment, they are increasingly being exposed to various risk factors such as forward secrecy and server impersonation attack. Therefore, researches for remote user authentication scheme have been studying actively. This paper overcomes the weaknesses of many authentication schemes proposed recently. This paper suggests an improved authentication scheme that protects user's anonymity with preserving variable more safe and also provides forward secrecy.
