Inventors of the year
In winter 2011, Intellectual Property Management and Technology Transfer (IPMTT) implemented Component I of its Intellectual Property Awards Program aimed at recognizing inventors of the year at the Canadian Space Agency (CSA).
The Selection Committee, composed of CSA directors general, presented the award to Xin Xiang Jiang and Darius Nikanpour, in recognition of their commitment to promoting and transferring the technology they themselves developed.
Component I of the IPMTT Awards Program not only pays tribute to a technology that has had a significant impact on the CSA and the Canadian government as a whole, but also underscores the inventors' participation in the intellectual property management process.
Usefulness of the invention
The invention developed by Xin Xiang Jiang and Darius Nikanpour, entitled "Method for Regulating Strain Output of Shape Memory Alloy Actuators" helps to achieve cost and space savings and reduce weight.
It also eliminates the need for position sensors for fine control of Shape Memory Alloy (SMA) actuators. A simple and effective topology for both actuation and control of SMA actuators has been developed and prototyped, enabling low cost control of one or many actuators using a minimum of hardware.
This technology can be integrated with a wide range of applications (opposite), particularly where SMA based actuation is desirable and where fine position control is a necessity.
