Inspection of old system and plan for installation

posted Jun 26, 2012, 10:17 AM by Tiberius Brastaviceanu   [ updated Jun 26, 2012, 10:17 AM ]

Today, June 26, 2012 we had a meeting with Dr. Sabah and Dr. Danialou at Meakins-Christie Laboratories, to see the type of system Dr. Danialou wants to have retrofitted for the Mosquito force transducer. We took some pictures (see album) and some measurements of a similar old system. In conclusion, we need to make the experimental bath, which will hold the sample within a controlled physiological medium. We also need to think about the mechanics to hold the Mosquito transducer and for sample manipulation. See the document containing notes taken during this meeting (members only). 

Project regains it's momentum

Last Friday we had another meeting with Dr. Sabah Hussein to discuss about the installation of another Mosquito system in his lab. This project was delayed for different reasons and it seams to have regain it's momentum. We already set up another meeting to plan the details for the installation. Dr. Gawiyou Danialou was also present, he will be in charge of the project.  

In this case, the Mosquito will be used at the tissue level, which means that we need to fabricate a stiffer force transducer. One idea is to use a larger core PMMA fiber. 

Work Party April 01, 2012

Some progress was made on signal conditioning for the new Mosquito. Open Work Party report. We are still in the process of choosing the proper amp chip, but we know better now. We also tried for the first time the photodiode in the biased mode. 
We finally decided on a prototype that can be presented soon at the Fondation du maire, our next grant contest. This same prototype will be installed in Sabah Hussain's lab.  

New architecture for the mosquito

Jonathan, Francois and Tibi had a Skype meeting, to brainstorm about opto-mechanical designs and electronics. They came up with new recommendations for architecture design and modules to be used. See the Mosquito device setup document for more. This news is relevant for Philippe's project and for Sabah's project.    

Moving into the lab

The work on electronics is almost completed and we are getting ready to move the Mosquito into the lab of Dr. Sabah Hussein. See the last report on electronics produced by Jonathan. Ivan had recently confirmed with Dr. Hussein to start bringing materials into the lab. 

We must also announce that we are now working  in parallel on a new version of displacement/force transducers that can fit the system destined for Royal Victoria Hospital of McGill University, the constriction transducer
