A New real-time position and orientation tracking system for endoscopy is described. Three coils sequentiallyfed with current comprise the excitation source which will produce magnetic field. According to Biot-Savart-Laplace law, flux intensity data detected by three-axis magnetic sensor could be interpreted into information that will reflect the sensor's specific position, thus realizing the position determination. Also, data detected by the magnetic sensor and gravity sensor changes in connection with the spatial angles. By researching the change law between the two, spatial angles of the sensor is calculated, thus realizing orientation determination. It is shown errors in position determination is,errors in orientation determination is , the tracking frequency of the system is 10 Hz.

Tracking Technology

Monitoring individuals or important things has never been simpler, thanks to advances in communication technology. A tracking device is an electronic unit intended to communicate its area, either in light of a sign or at set interims.Tracking devices can permit you to screen stock, find imperiled creatures, or help salvage laborers discover you in a crisis.So Real-time location tracking consistently takes on a vital job in the life of the person. Growth in advanced technology advancements such as 2 G, 3 G, 4 G, LoRa, and ZigBee has gained progressive changes in realtime location tracking. Technology only works when it reaches the user's every standard. This study explored the appropriate technology to track the real-time position amidst the technologies listed above.This paper proposed a model for real-time location tracking through a device that offers the ability to track the location in case of emergency. The tracking system involves the GSM-based GPRS activated unit that continuously transmits the moving object's GPS location to a mobile device that has activated the specified software and sends the SMS in an emergency to the registered mobile number.

Due to the existence of different grades of mineral in the mining area, the technology of slurry pipeline grade transmission is developing. However, the process of grade transmission will appear the phenomenon that the slurry of different grades are mixed. Therefore, before cutting into different grade slurry, we added special medium in pipeline to separate different grades of slurry. We worked out slurry pipeline transport model by mathematical modeling and building slurry pipeline transport real-time location tracking system. The system was able to distinguish different grades of slurry by adding special medium and tracking the actual location of the head and tail of slurry, realizing real-time position monitoring of different grade slurry.

This paper describes a system for direct position and orientation control of remotely piloted aerial vehicles using haptic force feedback. Motion capture hardware is used to provide real-time position and orientation information to the closed-loop flight control algorithm. A 3D simulation environment running in parallel with the vehicle control system provides real-time proximity/collision detection and flight volume constraints. Virtual coupling elements are used to connect a haptic user interface, the simulation environment, and the vehicle controller. An implementation of the system using an electrical radio controlled (RC) helicopter in an indoor environment is presented.

In a classical random walk model, a walker moves through a deterministic d-dimensional integer lattice in one step at a time, without drifting in any direction. In a more advanced setting, a walker randomly moves over a randomly configured (non equidistant) lattice jumping a random number of steps. In some further variants, there is a limited access walker’s moves. That is, the walker’s movements are not available in real time. Instead, the observations are limited to some random epochs resulting in a delayed information about the real-time position of the walker, its escape time, and location outside a bounded subset of the real space. In this case we target the virtual first passage (or escape) time. Thus, unlike standard random walk problems, rather than crossing the boundary, we deal with the walker’s escape location arbitrarily distant from the boundary. In this paper, we give a short historical background on random walk, discuss various directions in the development of random walk theory, and survey most of our results obtained in the last 25–30 years, including the very recent ones dated 2020–21. Among different applications of such random walks, we discuss stock markets, stochastic networks, games, and queueing.
