VGA digital fiber-optic converter for the use of computer-based specific monitoring, display occasions (such as conference centers, demonstration halls, checkpoints, cashier stations, military exercises monitoring station, etc.) will be the user's computer graphics card output content through the long-distance, real-time transmission of the digital channel to the remote terminal equipment (computer monitors, video walls, projectors, etc.) to display the demand for output, so as to achieve the computer VGA interface signal high resolution, no time delay, long-distance fiber optic communication conversion applications, can achieve a machine (computer) operation, multi-terminal (display terminal) display effect; VGA optic fiber optic converter at the same time can be extended to support the ultra-remote (several kilometers away) the mouse, the keyboard real-time monitoring, control functions, both ultra-remote "a machine to see more" and "a machine to see more" and "a machine to see more". The transmitter has a pass-through loop for local computer monitoring. The receiver has an output port. LED indicators on the transmitter and receiver show the status of the power, video and optical signals.The DVI Optical Transmitter System provides long distance transmission of computer video signals that require high resolution, making it an extremely flexible professional system. The system is specialized in professional A/V, security systems, campus environments, industrial monitoring, and large venues (stadiums) to meet the need to access computers or computer video signals from a remote location. This device supports one way DVI input, one set of optical output and one way VGA local monitoring output. With (multi-mode)/(single-mode) optical receiver with the use of support for the resolution of 800x600 (all refresh rates), 1024x768 (more than 70HZ), other resolutions and refresh rates with the screen, support for most of the display, but there will be a small number of screen display does not come out. Support VGA, PS2 port, audio, MIC interface.

With the rapid development of medical equipment technology and medical personnel knowledge level continues to rise in the field of medical imaging to expand a number of cutting-edge scientific research projects, in order to explore the wonders of the human brain's advanced functions and scientific analysis of human psychology, functional magnetic *** vibration imaging research technology is booming, the international establishment of a number of life sciences magnetic *** vibration brain Functional research centers have been established in the world, and the brain function technology has been gradually transferred to the preparation stage of clinical application on the basis of a large number of research results.
Functional magnetic resonance imaging (fMRI) is a rapidly developing new imaging technique that utilizes blood oxygenation level-dependent (BOLD) measurements to analyze the higher functions of the human brain. We use visual, auditory, motor, and visualization techniques to analyze the higher functions of the human brain. We use visual, auditory, motor, tactile, or cognitive stimuli to activate different areas of the brain, and we use high-resolution, non-invasive, functional magnetic*** vibration imaging to detect these activated areas.
2, the brain function of visual and auditory stimulation system audio and video structure and schematic diagram
Because of the special characteristics of the medical equipment and the nuclear magnetic *** vibration environment, the processing of all kinds of video images and audio transmission puts forward very demanding requirements: transmission of high-quality audio and video signals; the stability of the product; the product can run in a high magnetic field environment, the product and the high degree of integration with the field equipment. Huatiancheng set up a special team to carry out a lot of research and investigation for medical use, and Huatiancheng's professional solutions and products have been recognized by many customers in the industry.
1). Visual system: Text or pictures are transmitted into the magnetic **** vibration scanner so that the examinee receives visual stimulation or is instructed by the screen to perform a functional test. The use of NMR-specific corrective optics assists visually impaired patients with stimulation tasks.
2). Two-way non-magnetic audio system: transmits sound into the magnetic **** vibration scanner so that the subject receives auditory stimulation or is instructed by the sound to perform functional visualization.
3). Subject Response Feedback System: Keystroke feedback monitors the correctness of the subject's response and response time.
3. Audio-visual solution design for brain functional audio-visual stimulation system
Program description:
1). Video transmission: computer and DVD test image access to the audio and video switching controller, the output all the way VGA signal through a pair of VGA high-definition optical transmitter to the digital optical processing system.
2). Audio and return signal transmission: test music and microphone audio through a pair of dedicated multifunction optical transceiver transmission to the nuclear magnetic **** vibration room, so that the examinee receives auditory stimulation or by the sound of the instructions for functional visualization; examinee presses the healthy return signal through a dedicated multifunctional optical transceiver back to the control room to monitor the examinee's response rate and response time; both sides can be through the microphone speakers and headset Convenient to realize flexible communication between scanning room and control room
3). Nuclear magnetic room dedicated video monitoring system: in order to facilitate the observation of the love of the state of the examiner in the nuclear magnetic room, the examinee's examination process for the whole video recording and storage, to protect the safety of the examinee to facilitate the settlement of medical disputes. Nuclear magnetic chamber of the video monitoring system with a special ultra-small optical transceiver, integrated in the camera inside the optical signal transmitted to the control room to view the storage; completely high magnetic energy on the impact of video monitoring.
