TheTetra Universal Controller

Deseret News: SALT LAKE CITY — Four innovative University of Utah technologies will be exhibited at CES 2017, the world’s largest and best-known consumer electronics and consumer technology trade show, which runs Jan. 5-8 in Las Vegas.

This marks the U.’s third consecutive year at the event — and largest representation yet. The U. technologies on exhibit include:

• TheTetra Universal Controller, a device that expands the number of input commands to individuals with quadriplegia/tetraplegia who use “sip and puff” systems to control mobility devices.

The ability to perform complex actions or sequences in these current systems is significantly limited. The Tetra Universal Controller combines pattern recognition, timing and pressure intensity, which allows for a virtually unlimited number of control directives, giving users more control and independence over their lives.

The controller was developed by Jeffrey Rosenbluth, associate professor and medical director of the Spinal Cord Injury Acute Rehabilitation program; Ross Imburgia, research engineer in the division of physical medicine and rehabilitation; and Andrew Merryweather, assistant professor of mechanical engineering.

• Adaptive glasses, which are smart lenses that in less than a 50th of a second automatically put into focus what a user is looking at, whether that object is at a distance or up close.

The liquid lenses use a tiny laser and a small amount of electricity to autofocus. They are controlled by an electronic actuator that compresses or stretches the lens based on what the wearer is looking at, thus providing a variable aperture.

The glasses work in a similar way to bifocal spectacles in that they provide the user with a range of focus beyond that of traditional eyewear. The glasses were developed by members of the electrical and computer engineering department.

• UPlay Piano, an interactive, web-based instructional software program for teaching young children how to play the piano. Each lesson contains an illustrated story to introduce new concepts, demonstrations and game sections to teach theory and musicianship, piano pieces for practice and a test to reinforce knowledge of concepts.

The program employs a link to allow students to interact with the online website while playing on any electronic keyboard. The platform also includes an online database allowing parents and teachers to track student progress. UPlay Piano was developed by members of the music school.

• The Sentinel 100, a credit card-size board and chipset based on the work of Cynthia Furse, a professor and associate vice president for research, that enables engineers, equipment manufacturers and system operators to monitor electrical systems for critical faults in live electrical wires when embedded into a product.

The pediatric adaptive skiing system is one of more than nine funded undergraduate research projects under way at any given time within the Department of Mechanical Engineering. It is also one of over 250 funded undergraduate research projects campus-wide.   Working to build a pediatric adaptive skiing system, mechanical engineering sophomore Jacob Hopkin says, “It will be a novel device able to adapt to children with different levels of disabilities, as well as progress with these users as they learn to ski.”

Along with fellow mechanical engineering student Dallin Rees, Hopkins works one-on-one with mechanical engineering assistant professor Andrew Merryweather in the  Ergonomics and Safety Lab. “Dr. Merryweather is awesome! He is always willing to take time out of his day to meet. In fact, he almost missed an abstract submission because of his willingness. Sorry!”

Merryweather and Hopkins are hoping to have their skis on the snow soon for preliminary testing with the finished product deliverable in February.

From Pocatello, Idaho, Hopkins notes that, “Between loving everything outdoors, i.e. skiing, mountain biking, running, and a great engineering program, the University of Utah was a natural choice for me. Campus lies in an ideal area for all of those activities and beyond that, the U’s mechanical engineering program is competitive with the most prestigious in the west.”

“One of the benefits of majoring in mechanical engineering is that mechanical engineers know some of all engineering disciplines, which I believe makes for a more rounded engineer. Additionally, I like choices and a mechanical engineering degree opens the door for an advanced degree in other engineering majors. Regarding my current research, I love the project. It combines a large number of my interests. Plus, I am able to directly give back to the community.”

Device engineered by mechanical engineering seniors helps to expand outdoor activities for people with spinal cord injuries

 

(Al Hartmann-The Salt Lake Tribune) Danny Salazar uses a device developed by engineers at the University of Utah to steer a sailboat by slipping or blowing into a tube.  Dr. Jeffrey Rosenbluth, a rehabilitation doctor with the University of Utah, rides along with him on the boat. Salazar had never been on the water in his life, but sail for the first time at East Canyon Reservoir with TRAILS. TRAILS stands for Therapeutic Recreation & Independent Lifestyles that helps people with spinal cord injuries learn how to do outdoor-related actives like kayaking, sailing and camping.

TRAILS stands for Therapeutic Recreation & Independent Lifestyles that helps people with spinal cord injuries learn how to do outdoor-related actives like kayaking, sailing and camping.

Salt Lake Tribune: “We used to literally prescribe this kind of activity. We now try to make it part of the rehabilitation experience from the beginning,” Dr. Jeffrey Rosenbluth said. As director of the university’s spinal cord injury program, Rosenbluth typically works with his patients in a clinical setting. “Just knowing this possibility is out there is an amazing part of the process. Everything we do is sustainable. This is not diversionary recreation. It is something people with spinal cord injuries can do all the time.”

Danny Salazar can’t move his arms and legs, and he has a hard time breathing on his own. But the 29-year-old can blow and suck air through his mouth just enough to control a modified Mirage Tandem Island sailboat built by Hobie.

Salazar controlled the sailboat’s rudder via a “sip and puff” system like the ones used on wheelchairs. A senior project team of mechanical engineers from the University of Utah worked for two semesters on the sailboat. (Full Salt Lake Tribune story)

Green Machine selected nationally as one of six to compete

SONY DSCThe University of Utah Department of Mechanical Engineering Green Machine team was selected as one of six-finalist undergraduate projects nationwide invited to compete in the American Society of Mechanical Engineers Bioengineering 2013 Undergraduate Design Project Competition in Rehabilitation and Assistive Devices. The competition was held June 26-29, in Sunriver, Oregon.

The Green Machine is an autonomous garden cart that follows the user around the yard.  The green machine also has the ability to lift and dump to a height of a standard size trashcan.  Team members are mechanical engineering seniors, Taylor Grenis (lead), Brian Hutchings, Bryan Van Horssen, Clay Williams, and Kolby Sorenson.  Their faculty advisors are Larry DeVries, distinguished professor and Andrew Merryweather, assistant professor in mechanical engineering.

The students generated the original idea for this project.  Team member Kolby Sorenson noted, “Having grandparents who love to garden, but struggle to transport soil, plants, and rocks around their yards, we realized that an electric yard wagon could help them to do what they loved.  Then we realized that this machine could help all people with physical disabilities.  It could do the heavy lifting for them, and follow them to wherever they needed it.”

Sorenson continued, “We were expecting advice on Solid Mechanics and Dynamics calculations, from our faculty advisor, mechanical engineering Distinguished Professor Larry DeVries.  He surprised us with a wealth of knowledge we were not expecting.  In addition to the technical needs, he helped us to make the Green Machine user-friendly and to construct our project schedule.  He even donated his stipend from the NSF grant back into the project.”

The Green Machine undergraduate project was one of 23 senior design projects showcased during the Department of Mechanical Engineering Design Day held on April 16, 2013, in the Olpin Union Building.  The Department of Mechanical Engineering at the University of Utah is committed to providing students with broad-based, rigorous and progressive education.  By combining state-of-the-art facilities with renowned faculty, the department provides an education that gives students the necessary skills to become the next generation of innovators.

Utah Mechanical Engineering students win Ergonomics Competition

ergoAwardAndrew

ErgoLink, a design team made up of students from the University of Utah’s Department of Mechanical Engineering, won first place in the eTools Ergonomic Design Competition on march 22, 2010 for demonstrating superior ability to solve ergonomic related design problems. The event was sponsored by Auburn Engineers Inc.

“We had to redesign a backpack and a hand-held packaging tape dispenser—two common consumer products—as part of a multi-phase competition,” said Rami Shorti, ErgoLink’s team leader and mechanical engineering student at the University of Utah. “Our team was able to evaluate both products, and come up with innovative ways to improve their overall design, making them more ergonomically sound.”

As part of their evaluation process of the backpack, members of ErgoLink surveyed fellow college students to see how they used their backpacks, how much weight they usually carried in them, and which features they would like to see improved. After completing their evaluation, Ergo Link decided to make the backpack thinner by moving the center of mass closer to the body, reducing moment or torque on the lower back. They also added wider shoulder straps to help distribute the weight and reduce stress on the shoulders.

ErgoLink competed against seven teams from six universities and was presented with the award at the 13th annual Applied Ergonomics Conference. ErgoLink’s team members are: Rami Shorti (Team Leader), Sree Harsha Jampala, James Nolin, Chris Brammer, and Jason Kraft.
