TSI Opens Our New Office!

TSI has a new home – back in great Town of Stouffville.  We opened our brand new facility in May 2016, and are now settled in and in full production.  This new new space allows us to increase our services significantly by expanding our lab and adding prototype fabrication capabilities.  We can now do in-house fabrication and assembly, 3D printing and testing.  All of this added to our upgraded servers and compute resources will help us do more and faster.

The new location is:

50 Innovator Avenue – Suite 11
Stouffville Ontario L4A 0Y2

TSI Labs helps our military with biomechanics and new product solutions!

TSI and our TSI-Labs venture together with Dr. Steve Fischer, and Queen’s University, have recently published findings of an in-depth project to understand and mitigate neck pain in military flight crews.  This significant problem has been affecting our women and men for many years.  In a matter of mere months, our team was able to get to the root of the biomechanical problem, develop prototype devices as short-term counter-meausures and evaluate their effectiveness in real-world conditions.  The results are very promising, and the ongoing work will one day lead to significant improvements in operational and everyday life for those that serve us.

Focused research – at the speed of business!

LS-DYNA modeling helps develop engineered cartilage

The Annals of Biomedical Engineering has published “The effect of moving point of contact stimulation on chondrocyte gene expression and localization in tissue engineered constructs.” , a paper by Jake Kaupp. Markus Hetzler and our Thumbprint Solutions team contributed advanced numerical modeling to help understand the behaviour of seeded agarose gel under cyclic loading.  This viscoelastic material is extremely complex, and we successfully developed and applied material model development techniques using numerical optimization to create and validate the material models.  Ultimately this work will help develop new materials for joints.

New Paper in JSES

The Journal of Shoulder and Elbow Surgery has recently published “Factors affecting the stability of reverse shoulder arthroplasty: a biomechanical study“, a paper by Allison Clouthier. Markus Hetzler of Thumbprint Solutions contributed as a second author as part of his own ongoing graduate studies.

Biomechanical Simulator for Queens University

TSI has recently released a biomechanical simulator to support cutting edge research at the Human Mobility Research Centre at Queens University in Kingston.

The test machine was developed to enable the research team to study the stability of prostheses, in this case a reverse shoulder arthroplasty.

TSI developed and supplied a fully integrated system, comprising of three series-elastic actuators, which reproduce the muscle forces, and a fourth actuator to apply external perturbations (dislocations) to the joint.  The four channels operate independently or coupled, using displacement and/or force control and have real-time tracking of the loads and position.

The system provides a high force fidelity, low impedance and excellent control bandwidth solution at a low overall cost.  It is powered by modular and expandable custom electronics hardware and controls software developed in-house by TSI, and most importantly, it has an intuitive, open-source interface.

Not only did we provide an effective physical solution, we provided a platform for innovation, allowing the team at Queens to focus their efforts on what is important – the research itself.
