February 2020- Teuscher Lab summer interns accepted for MIT THINK Scholars Program

High schools students Ishaan Sinha and Owen Caverly wanted research experience so they reached out to some professors. Dr Teuscher agreed to have them intern in teuscher.:Lab last summer. Their experience helped them get accepted for the MIT THINK Scholars Program where they received a four-day all-expenses paid trip to MIT to meet professionals in their field of research, tour labs, and attend MIT's xFair. While there, they met a professor who is offering to fund their project, as well as invite them to his summer institute.

Their research project this summer was EyeHear: Smart Glasses for the Deaf and Hard of Hearing. Dr Teuscher connected them to some resources, such as an anechoic chamber and a loan of a Google Glass Explorer Edition. Great job Ishaan and Owen!

November 2019- ECE students published in Nature
Former ECE PhD student Walt Woods and ECE student Jack Chen have a Machine Learning article accepted and published in Nature.

June 2019 - ECE Visiting Professor Ephraim Suhir receives the IEEE Field Award in Electronics Packaging at the 69th IEEE Electronic Components & Packaging Conference in Las Vegas. The IEEE field awards are the highest in the specified technical areas.
 

“For seminal contributions to mechanical reliability engineering and modeling of electronic and photonic packages and systems.” 
With over 40 years of pioneering work in modelling and reliability engineering, Ephraim Suhir has enabled electronic packaging engineers to accurately predict stress in advanced packaged components for the design of more reliable devices. He was one of the earliest researchers to introduce the use of rigorous mechanics principles in electronic systems. His closed-form solutions have provided the electronics industry with invaluable tools for ensuring reliability and cost savings during the design process by eliminating errors early in the design process. He has applied his techniques to advanced components and packaged structures such as microelectronics, photonics, photo-voltaics, and thermoelectronic modules. Every serious mechanics practitioner and researcher in the electronics packaging field has been influenced by Suhir’s groundbreaking contributions.

May 2019 - Dr. John Lipor awarded NSF grant

Dr. Lipor's research will focus on the design, analysis, and deployment of algorithms for adaptively sampling the environment with mobile sensors. Phenomena such as harmful algae booms and wildfires regularly impact the Portland area and Oregon as a whole. In the latter case, a key task is understanding the spatial extent of airborne particulate matter resulting from fires. This research seeks to design algorithms that adaptively track this spatial extent while accounting for practical considerations, such as the time required to travel between sampling locations and the need to recharge the vehicle.

Congrats to the ECE students who have made it to the finals of the Cleantech Challenge with their Living Window project!

From Stevie: Our project Living Window is being worked on by the members of Portland State Product Innovation (PSPI), a club at PSU, led by team members Stevie Taylor, William Lau, and Talya Naftali. The Living Window is a greenhouse inside of a wall with automation, phone app, hydroponics, and plumbing components among others. We plan to bring this project as far as possible within the Cleantech Challenge and InventOR should we make it that far, and beyond. Anyone interested in working on this project, or other projects, or want to find other people to work on your pet project with us should join a PSPI meeting which take place every Friday from 5:30pm-7:30pm in EB 421. Email portlandstateproductinnovation@gmail.com to join the mailing list or ask for more details about PSPI or the Living Window.

January 2018 - New Robots in the Robotics Lab

HROS5 (Humanoid Robot Research Platform)

We have three HR-OS5 (Humanoid Robot Research Platform) robots in our lab. These robots are especially great for robotics research. What makes these robots more expensive and advanced than the competitor robot platforms is their powerful high accuracy smart servos motors. Each robot has its own unique 3D printed covers which not only make them look different, but also helps us define their unique personalities. Another very important advantage of these robots is that they are very easy to modify and cheaper to keep well-maintained  compared to the other robots. Currently, we are working on improving the robot's software by adding new features and abilities such as robot motion generating, walking, and computer vision.

Turtlebot2i

Turtlebot is one the best robots to not only start learning about robotics, but also to learn more about advanced robotics topics in order to do interesting robotics projects. They are low cost, very reliable and, most importantly, very well-documented. They are also very easy to modify, so we can easily use them in many different robotics applications. The robot comes with a wheeled robotic base, two 3D cameras used for navigating and object and obstacle detection, and a robotic arm used for picking up and placing objects. Intel has graciously donated us three of these robots.

June 2017- Dr. Bird Receives DOE Grant
In June Dr. Bird was awarded an $800k DOE grant that will involve developing a multistage, magnetically geared generator with airtight casing to improve the cost, reliability, and efficiency of marine hydrokinetic generators. Increasing the gear ratio through the multistage design reduces the generator size, which in turn reduces the structural support required, thereby lowering costs. The magnetic gearbox, which creates speed change without physical contact, minimizes operations and maintenance costs and provides protection from overloading during extreme events.

June 2017 -Dr. Perkowski Presents at IEEE Conference in Slovakia
Dr. Marek Perkowski presented an invited keynote address at the International IEEE Conference on Information and Digital Technologies 2017 in Zilina, Slovakia on July 7, 2017. It was entitled  "A uniform approach to create quantum Grover oracles for partition problems" and was related to several quantum algorithms for Machine Learning and automata design that can be used in quantum robotics.
