AI Thread Summary
The discussion focuses on the RNS neurostimulator, a device implanted in the skull to manage epileptic seizures by detecting EEG signals and delivering electrical charges to disrupt seizures. The system consists of a detection component and a control portion, utilizing either synchronous or asynchronous sensor chips for detection. There is confusion regarding the differences between synchronous and asynchronous detection methods in this context. Clarification is provided that synchronous detection involves a clock signal, while asynchronous detection relies on data transmission without a clock. The conversation also highlights a broken link to a related document, which is in French, and requests for specifications regarding the device.

hello,
We work on a topic concerning the RNS neurostimulator against epileptic seizures:
http://latavernedes3i.free.fr/files/...20Valerian.pdf

(RNS consists of a computerized device implanted into the skull with electrodes implanted in presumed epileptic foci in the brain. Brain electrodes send EEG signals at the input device that contains detection software. When certain criteria EEG seizure are satisfied, the device delivers a small electrical charge to the electrodes other near the epileptic focus and disrupt the seizure.).

the system has two main parts:
- Detection part:
- Portion control (FPGA processor ...)

detection is assured either by a sensor chip synchronous or asynchronous
After much research, I can not differentiate between an asynchronous and the synchronous detection in this context:confused:
and thank you for your help

Your link appears to be broken. I tried to repair it, but got a nasty message when trying to enter the home website. Can you re-post your link?

Yep, it's in French all right...:smile:

On your question, synchronous would normally refer to when you are clocking the device that you are communicating with, and asynchronous would be when the device is sending you its own clock along with the data. Or asynchronous could mean that the device is sending you just the data, at some known pace (like with RS-232 communication, there is no explicit clock sent with the data, but the data rate of the sender and receiver must be the same in order for the communication to work).

Do you have any specifications for the device that you are communicating with? Or is that somewhere in the French document?

Thread 'Weird near-field phenomenon I get in my EM simulation'

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
