Each year senior engineering students in RIT’s Kate Gleason College of Engineering work on challenging projects as part of the Muldisciplinary Senior Design (MSD) program. This two-semester capstone experience builds upon previous coursework by integrating engineering theory and practice within a collaborative environment. Working in multi-disciplinary teams and following an engineering design process, students assess customer needs and engineering requirements, evaluate concepts, resolve major technical hurdles, and employ rigorous engineering practices to design and build a prototype device or process which is fully tested and documented. MSD is a studio course – it adopts an approach to student interaction that is hands-on, instructor facilitated, and student-centered. Students from other colleges (eg. software engineering, industrial design, business) are encouraged to participate. Projects may be proposed by students, faculty, companies and other external sponsors. Each project requires participation of a RIT faculty member who marshals the proposal through an approval process. Priority is given to projects that fall within one of the technology “tracks,” which are consistent with educational options and research priorities: Biomedical Systems, Energy and Sustainable Systems, Vehicle Systems, Autonomous Systems and Controls, Printing and Imaging, Chemical and Materials Processing, and Process Innovation.

RIT students develop deep-sea explorer

Dan Scoville ’05, left, and Matt Paluch, a fifth-year electrical engineering major, lower

an underwater remote-operated vehicle into Judson Pool in the Gordon Field House and Activities Center for testing. The device, designed and built for a senior design

project, will be used to explore Lake Ontario shipwrecks this summer.

It’s designed to explore the depths of large bodies of

water—and one recent weekend, that’s exactly where

it was found: searching the depths of the deep end of

Judson Pool in RIT’s Gordon Field House and Activities Center. (As the adage goes, every journey begins with

a single step.)

The explorer, an underwater remote-operated vehicle,

or ROV, is the senior-design project of a team of RIT

engineering majors—and it has been described as one

of the most ambitious and challenging student projects ever at RIT. This spring and summer, the device will

be used to explore century-old shipwrecks resting on

the bottom of Lake Ontario and the Atlantic Ocean and

give human explorers their first glimpses of some all-

but-forgotten vessels lost to the seas.

The RIT team is led by Dan Scoville ’05 (B.S. electrical engineering) who, partnering with Jim Kennard, has

located and explored three “virgin” (previously

undiscovered) shipwrecks in Lake Ontario in the past

five years. The duo now has its sights set on two

undisclosed Lake Ontario shipwrecks (the names and

precise locations of the vessels won’t be revealed until

this fall) and, working with the Undersea Research

Center at the University of Connecticut, the steamship

Portland, which sank off the coast of Gloucester,

Mass., in 1898.

The steering wheel of the Etta Belle, which sank in Lake Ontario in 1873. The vessel

was discovered two years ago by a team including Dan Scoville '05. Scoville will return to the lake this summer with an underwater remote-operated vehicle—built by

a team of RIT engineering majors—in search of other shipwrecks.

One of the sunken crafts in Lake Ontario is a 1800s-

era schooner. Scoville, who personally backed the ROV

project financially, says locating and documenting

shipwrecks is important due to their connection to the

Rochester area’s maritime history. Lake Ontario, he adds, is a huge but vastly underused resource for

learning about watercraft from a bygone era and the

technology used to find them and preserve their

histories.

Some of the fewer than a thousand ships lost in Lake

Ontario have been discovered and salvaged, while others are in water too deep to explore, Scoville says.

That leaves a small number—perhaps a dozen—in the

100-to-400-foot-depth range in the area from the

Niagara River to Oswego accessible to explorers such

as Scoville and Kennard. But they’re not easily found,

Scoville adds. Even after they’re located they can’t be

salvaged because those between the shores of New

York and the international line are considered state

property.

“We do it because we love doing it,” says Scoville, an electrical engineer with Eastman Kodak Co. and a

scuba diver for about 10 years. “When you find one,

it’s neat. It’s a really cool experience.”

Old Warship Found Intact in Depths of Lake Ontario By THE ASSOCIATED PRESS

A 22-gun British warship that sank in Lake Ontario during the American Revolution, has been discovered by two shipwreck enthusiasts. It is the only fully intact British warship ever found in the Great Lakes. The enthusiasts, Jim Kennard and Dan Scoville, used side-scanning sonar and an unmanned submersible vessel to locate the ship, the Ontario, which was lost with barely a trace during a gale in 1780. The ship had as many as 130 people aboard. “To have a Revolutionary War vessel that’s practically intact is unbelievable,” said Arthur Britton Smith, a Canadian author who chronicled the history of the Ontario in a 1997 book, “The Legend of the Lake.” “It’s an archaeological miracle,” Mr. Smith said. Mr. Scoville and Mr. Kennard announced their discovery on Friday. They said they regarded the wreck as a war grave and had no plans to raise the Ontario or remove any of its artifacts. The ship, they said, was still considered the property of the British Admiralty. The vessel lies in water up to 500 feet deep and can be reached only by experienced divers. Mr. Kennard and Mr. Scoville declined to give its exact location, saying only that it was found off the lake’s southern shore. The Ontario, an 80-foot sloop, was described as resting partly on its side, with two masts extending more than 70 feet above the lake bottom. “Usually when ships go down in big storms, they get beat up quite a bit,” Mr. Scoville said. “They don’t sink nice and square. This went down in a huge storm, and it still managed to stay intact. There are even two windows that aren’t broken. Just going down, the pressure difference, can break the windows. It’s a beautiful ship.” Mr. Smith, who was shown underwater video of the discovery, said, “If it wasn’t for the zebra mussels, she looks like she only sunk last week.” The dark, cold water acts as a perfect preservative, Mr. Smith said. At that depth, there is no light and no oxygen to hasten decomposition, and little marine life to feed on the wood. Explorers had been searching for the Ontario for decades, and there had been many false finds, said Eric Bloomquist, the interpretative programs manager at Old Fort Niagara. Mr. Kennard, an electrical engineer who has been diving for about 40 years and has found more than 200 wrecks in the Great Lakes, Lake Champlain, the Finger Lakes and in the Mississippi and Ohio Rivers, began searching for the Ontario 35 years ago but quit after several frustrating and fruitless years. Six years ago, he teamed with Mr. Scoville, a diver who developed a remote-controlled submersible vessel with students from the Rochester Institute of Technology. Since then, the men have found seven ships in the lake. Over the years, Mr. Kennard obtained documents from British and Canadian archives on the Ontario, including the ship’s plans. Mr. Scoville and Mr. Kennard searched more than 200 square miles for three years before finding the ship this month. After locating the wreck with the sonar, the explorers used the submersible vessel to confirm their discovery and document it with more than 80 minutes of underwater video.

Senior project sheds new light on the RIT campus

Jeff Hoover, left, Jessie Gmeinder and Chris Chaput, fifth-year mechanical engineering

majors in the Kate Gleason College of Engineering, are part of a 10-person team that

designed a wind-turbine-powered walkway light as a multidisciplinary senior-design project. The light, turbine and control box were permanently installed near F Lot and

Cross Campus Drive last month. A. Sue Weisler | photographer

It’s a green light, but it doesn’t signal “go.” That’s

because it’s “green” environmentally, not in hue.

To most passersby, the wind-powered walkway light—the

only one of its kind on campus—and its telltale “flutter-effect” sound have gone largely unnoticed, guesses Jessie

Gmeinder, a fifth-year mechanical engineering major in

the Kate Gleason College of Engineering and member of a

team of RIT students that designed and, last month,

installed the illuminator as part of a senior-design project.

But being in the limelight wasn’t the students’ aim. Rather, their project—one of seven in a new sustainable

design and product-development track for

multidisciplinary senior design—focused on exploring the

capabilities and limitations of sustainable technologies on

the RIT campus and determining their feasibility for

widespread use.

Air supply

Gmeinder, the chief engineer on the 10-person team of mechanical engineering and industrial and systems engineering students, and

Jeff Hoover, a fifth-year mechanical engineering major, recently showed off the walkway light on an atypically balmy April afternoon. As

if on cue, a gusty wind kicked up, causing the carbon-fiber-composite-reinforced blades of an AIR-X wind turbine atop a lamppost to

rotate into a blur. The resulting flutter—no louder than the engines of most passing automobiles on Cross Campus Drive—was barely

discernible.

Pedestrians using a pathway adjacent to F Lot probably notice the large control box mounted near the bottom of the post more so than the whir of the 46-inch diameter rotors mounted 17 feet above their heads. Behind the padlocked door of the control box are an

ammeter, analog and digital voltmeters, and two 12-volt deep-cycle batteries that are connected “in parallel”—both accepting power

generated by the wind turbine and supplying power to the 20-watt light-emitting diode (commonly termed LED) lamp. Or, as Gmeinder

explains, “The turbine talks to the batteries and the batteries talk to the light.” (The enthusiastic Gmeinder is as comfortable talking

‘tech’ as she is at explaining what it means in layman’s terms.)

The 13-pound, 400-watt-output wind turbine—made of aircraft-quality aluminum alloy castings—can generate power from as little as a

breeze of seven miles per hour or from wind gusts of up to 30 mph. (At speeds higher than 30 mph, an electric brake stops the blades to prevent overcharging the battery and over-revving that could damage the blades and bearings, and to keep electrical components

safe from a current spike.) A photocell—a device that detects daylight—turns on the light after dark (just like most streetlights).

None of it would be possible without a sturdy lamppost and concrete base—both provided, at no cost to students, by RIT Facilities

Management Services, which assumes guardianship of the light after students graduate this month. Additionally, James Watters, RIT

senior vice president for finance and administration, approved project funding of $3,500. (The project is currently under budget,

Gmeinder notes with a sense of satisfaction.

RIT is looking at numerous ways to reduce the university’s reliance on power from carbon-producing sources, Watters told the senior-

design team at a May 4 presentation. “This is a terrific project,” he remarked.

Professor takes methodical approach in smoking study

‘Smoking machine’ measures particle inhalation and effects on human body

RIT students constructed a smoking simulation device which models how cigarette smoke impacts individual organs in the body. A. Sue Weisler | photographer

Research at RIT is seeking to enhance knowledge

surrounding the impact of smoking on human health. Risa

Robinson, associate professor of mechanical engineering,

is utilizing computational modeling, medical imaging and

mechanical simulation to illustrate how individual particles

inhaled with cigarette smoke affect the body and how

they travel from the lungs to other organs.

The effort includes the construction of a smoking machine, built and designed by RIT students, which will

be used to simulate how these particles build up over

time and the impact the process can have on damaging

the body’s particle-clearance mechanisms. They are

particularly interested in the impact smoking has on

teenagers, whose lungs are affected to a greater extent

due to having smaller airways. The research is funded

through a grant from the American Cancer Society and is

being conducted in cooperation with RIT’s Departments of Medical and Biological Sciences and Medical Illustration.

“Previous research on the impact of particle deposits has focused on inundating laboratory samples with toxins and studying the

response, the so-called ‘avalanche’ approach,” notes Robinson. “The work at RIT uses a ‘snowflake’ method whereby particles are

allowed to build up over time, as they would in the body.”

Robinson believes her research can provide better evidence of the real-time effects of smoking and more properly link how particle

buildup impacts numerous systems in the body. She also hopes to shed light on how these particles can impact passive smokers, through secondhand smoke, and use her data in additional types of particle analysis, including studying the impacts of nanoparticles

and allergens.

“Through the use of new computational and imaging technologies we can learn more than ever before about how particle inhalation and

buildup affect human health,” Robinson adds. “This information will increase our knowledge of the negative effects of smoking and air

pollution, while also providing needed information to enhance treatment, including better application of inhaled medications.”

Robinson’s collaborators include Kathleen Lamkin Kennard, assistant professor of mechanical engineering, and Richard Doolittle,

professor and head of the Department of Allied Health Sciences, both at RIT; Todd Pagano, assistant professor of science and

mathematics and Director of the Laboratory Science Technology program in RIT’s National Technical Institute for the Deaf, and

undergraduate and graduate student researchers.

Device measures, enhances image quality

The micro-goniophotometer was developed by RIT researchers to enhance the

measurement of the specular effect known as gloss. Submitted photograph

When looking at an image, either digital or printed,

most people first decide whether it looks good.

However, that decision is obviously arbitrary and

based on opinion. So, how do specialists decide what

looks good when creating printed documents or digital

images? In other words how do you quantify quality?

Researchers in RIT’s Print Research and Imaging Systems Modeling Lab are trying to answer these

questions through the development of a device that

greatly enhances the measurement of image quality.

The micro-goniophotometer, designed and built by

laboratory staff, measures the optical phenomenon

known as gloss, which is used in the print industry to

measure material appearance. The device specifically

relates instrumental measurements to the characteristics of gloss and gloss variation.

“Since the invention of the printing press, researchers

have been trying to combine the ‘left-brain’ need to

measure and analyze performance with the ‘right-

brain’ understanding of what looks good,” notes Jon

Arney, an associate professor of imaging science and member of the research team. “The characterization of

gloss is one technique that has been developed to

address this challenge, but traditional gloss meters

have provided insufficient information to fully

characterize the phenomenon.”

According to Arney, the micro-goniophotometer improves upon previous measurement techniques by providing a 180-degree range,

which is double that of normal gloss meters. The increased trajectory allows for the measurement of specular light over a number of angles and spatial dimensions, greatly improving the accuracy of the results. An analysis of the device’s performance is provided in the

July/August issue of the Journal of Imaging Science and Technology and includes a comparison to traditional measurement techniques.

The research team has also worked with a number of imaging companies, including Hewlett Packard, to implement the device in

manufacturing operations and is currently investigating further commercialization opportunities. In addition, the International Standards

Organization, a global body that provides industry standards for the printing and imaging sectors, is looking to implement the micro-

goniophotometer as one of its chief methods for gloss measurement. The team also hopes to ultimately design a portable version of the device, which will enhance its usability and reduce costs.

“The measurement of gloss is a key component in the development of printed images and it is my hope that the dissemination of the

micro-goniophotometer will enhance both research in the field as well as the overall quality of printing,” adds Arney.

Students design innovative heart pumps

levitated axial-flow left ventricular assist device, an innovative heart pump that could

reduce the need for heart transplants. A. Sue Weisler | photographer

The Kate Gleason College of Engineering’s

multidisciplinary senior design program provides a

unique opportunity for students to gain hands-on

expertise and participate in top-level research while

still in college. In addition, a number of the designs

created through the program ultimately have

significant real-world impacts, enhancing the

development of numerous innovations and even

saving lives.

For example, a 2008 student design team formulated,

developed and constructed a test stand which is being

used to measure the performance of a new type of

heart pump called a magnetically levitated axial flow

left ventricular assist device. The pump, developed by

a team led by Steven Day, an assistant professor of

mechanical engineering, is more gentle and durable

than other types of devices, improves overall performance of the heart in people with various forms

of heart disease and could ultimately reduce the

number of patients requiring heart transplants.

“This project has been incredibly gratifying both in

allowing all members of the team to work on high-

level research and in giving us an opportunity to help

make a real difference in people’s lives,” notes Jim Cezo, a fifth-year mechanical engineering major and

member of the design team.

“The work of the student team has been tremendous and the device they have developed will be extremely useful in furthering the

development of this technology,” adds Day. “I have one other team working on a different aspect of the pump and hope to involve

additional multidisciplinary design teams on different aspects of this project as we move forward.”

The test stand simulates the flow of blood in the body, and researchers can vary the pressure of fluids passed through the system to

test the heart pump’s performance under a variety of conditions. The device is completely automated and communicates data to

computers both on and off campus. Day is using the device to evaluate a prototype version of the pump by running several pumps for

two straight years and hopes to begin the process of seeking approval from the U.S. Food and Drug Administration in 2010.

“This project has been a very rewarding way to engage students through senior design projects, co-op and graduate theses,” says Day.

“We hope that the pump developed at RIT might someday be used to save lives and that helps keep everyone motivated.”

Interactive game for visually impaired child wins student design award

RIT undergraduates develop teaching game designed for 9-year-old

Members of the RIT senior design team are congratulated by the Fortner family of

Rochester. The team designed an interactive game for their son, Luke, that won the 2009 IEEE Student Design Award. (Front row) Mike Fortner, Jack Fortner, Luke Fortner,

Students from Rochester Institute of

Technology designed and built an interactive

game for a visually impaired 9-year-old that

entertained and educated as well as won

first place in the 2009 Institute of Electrical

and Electronics Engineers Student Design Awards contest this past summer.

The multidisciplinary team from RIT was

awarded $5,000 for the small, rechargeable,

battery powered, hand-held device it built.

Students incorporated an LCD display,

tactile feedback motors, stereo speakers

and a simple user interface to build a model

that was both fun and focused on a 9-year-old’s sensory development.

Two years ago, a local physician, Dr. Julie

Lenhard of Perinton Pediatrics, contacted

RIT to design and build a handheld game to

help a patient with a visual impairment,

says Jesse Muszynski,a sixth-year electrical

engineering student and member of the RIT

IEEE student chapter. The child recognized

shadows, lights and color but had difficulty reading a book. The purpose of the game

was to offer entertainment during office

visits as the doctor and parents discussed

the child's progress.

“The team’s success can be attributed to the diversity of its members,” says Muszynski. “It was truly a multidisciplinary group because of all the majors involved.”

The undergraduate students involved in the winning design project are Christopher Yang, Nick Babin, Alana Malina, Ketan Surender,

Neil Pinto and Muszynski from the Kate Gleason College of Engineering; Robert Modzelewski and Pei Hong Tan from the College of

Imaging Arts and Sciences; and David Carmichael and Claude Jerome from the Golisano College of Computing and Information

Sciences.

“This team quickly applied their knowledge and were engaged from start to finish in developing this game for Luke, the child,” says

George Slack, lecturer, electrical and microelectronic engineering departments, who supervised the design project. “They worked patiently with Luke to better learn his needs, developed multiple concepts, performed frequent revisits to test their prototype ideas and

finally completed a very sophisticated design which proved to be extremely innovative with the reliability of a finished product.”

This was the ninth annual design contest sponsored by Fairchild Semiconductor, RIT’s Department of Electrical Engineering and regional

chapters of the IEEE, the international, professional organization that supports advances in engineering, computing and informational

technologies. Funding for the design portion of the RIT project came from a grant from the National Science Foundation.

Seniors present multidisciplinary engineering design projects

Projects range from artificial limb equipment to all terrain vehicle improvements

Ashley Shoum explains how the team developed the Automatic Shift Controls for

an ATV to Mark Kempski, professor of mechanical engineering.

A sign of spring is often the robins and returning geese. For RIT engineering students it’s a review of senior multidisciplinary design projects. More than 30 teams of students in the Kate Gleason

College of Engineering presented both completed and mid-project reviews at the end-of-quarter program.

Engineering students are required to participate in the multidisciplinary senior design course, a two-quarter sequence. A poster session took place last week in the Erdle Commons complete with exhibits of robotics designs and all-terrain vehicle engine improvements.

One of the noisier, but more impressive presentations was the Air Muscle Artificial Limb Next Generation project. Eva Ames and Jim Breunig, both fifth-year mechanical engineering students, explained that the life-sized hand and arm is a tool to be used in surgical procedures. Many gathered around Ashley Shoum, team lead for the Automatic Shift Controls project and the Polaris all-terrain racing vehicle. She and her team from mechanical, electrical and industrial and systems engineering explained the intricacies of developing ‘intelligent shifting’ for manual transmissions for the high-performance race ATV. Intelligent shifting is an automated process designed by the team to allow for automatic shift control with manual override for race as well as general use. Shoum and several others from the ATV team are also part of the Formula car team.
