    Project Number 1

    Project Name Central-Suction Electrocautery Pen

    Faculty Name Dr. Dan Adams ([email protected])

    Project Description Many surgical procedures require

    electrocautery, in which blood

    vessels are burned and sealed to stop

    bleeding. However, electrocautery

    produces a smoke plume, which

    limits the surgeon’s visibility and

    causes breathing problems for the

    surgeon as well as other members of

    the surgical team. This problem if

    often addressed using a variety of

    vacuum-based fume exhaust systems.

    The primary challenge associated

    with smoke removal is that the vacuum source must be placed in close proximity

    to the cauterization site to be effective, and yet it cannot obscure the vision or the

    procedures of the surgeon.

    This project will focus on the development of an electrocautery pen with an

    integrated central suction core that removes all electrocautery-produced smoke.

    Through the use of a suction tube integrated into the electrocautery pen, the

    vacuum source can be placed directly in front of the cauterization site while

    minimizing visual obstruction of the surgeon. Other design considerations will

    include an ergonomic design with full functionality and the elimination of possibly

    entanglement of the suction and electrocautery cords.

    This senior design project is being sponsored by a Salt Lake City surgeon, who

    will provide the required equipment (such as standard electrocautery pens and

    vacuum exhaust equipment) and any supplies required for the successful

    completion of the project. Additionally, students will be provided access to the

    operating suite as needed.

    Project Number 4

    Project Name Powered Swim Wheelchair

    Faculty Name Andrew Merryweather ([email protected]) & Dr. Jeffrey Rosenbluth

    Project Description Currently it is difficult and

    inconvenient for persons in

    wheelchairs to independently

    transfer in and out of bodies of

    water such as lakes and pools. A

    waterproof powered wheelchair that

    can be operated independently

    would enable the user to enter and

    exit recreational swimming areas

    more comfortably. The objective of

    this project is to design a powered

    wheelchair that will enable persons

    with varying levels of disabilities,

    including paraplegics and

    quadriplegics, to independently

    enter and exit a recreational body of

    water. The customers that will be operating this wheelchair highly value

    independence and this project is focused on giving these individuals a more

    independent and safe way to go for a swim in a recreational setting such as a

    lake.

    Project

    Objectives/Desired

    Outcomes

    Key Focus Areas:

    The device will be designed such that it can be operated by the user

    autonomously. The mobility platform will be waterproof, such that it can be

    completely submerged without damage to any of its systems. The mobility

    platform will be able to traverse several different kinds of terrain including

    gravel, sand, and dirt.

    Project Engineering

    Skills Mechanical: the mechanical system will involve the connections and drive

    system. Incorporated into the drive system are all components related to the

    locomotion of the device. Along with this, is also included all structural

    components and frame assemblies.

    headrests and footrests will be designed to be fully adjustable in order to

    accommodate a variety of customer preferences and comforts.

    * Safety: the safety area will involve the creation of a necessary components and

    systems that will enable the wheelchair to operate without reasonable danger of

    injuring the operator or any assisting individual who may accompany the

    operator.

    Project Number 5

    Project Name Wireless shoe-embedded perturbation device

    Faculty Name Dr. Andrew Merryweather ([email protected])

    Project Description We constructed a prototype of shoes

    that can deliver an unexpected or

    expected perturbation during

    overground gait. The basic prototype

    can deliver unexpected and expected

    (through an auditory warning tone)

    perturbations for a single step, but

    the device can be improved through new mechanical and control system

    designs.

    Our current applications are seeking to use this shoe as a rehabilitative tool in

    people with balance problems. We are seeking to improve the hardware design

    and integrate the control of the shoe into wireless platforms to enable reliable

    external control. The key advancements sought in this project are improving the

    durability of the device and enabling wireless communication within a compact

    package.

    Project

    Objectives/Desired

    Outcomes

    1. Full motion of arm completed in under 125 ms. 2. Total package contained within the sole of a shoe. 3. All wireless communication to external control within 50 foot range.

    Project Number 6

    Project Name Ultrasonic power and data feedthrough for pipelines

    Faculty Name Dr. Shad Roundy ([email protected]) and Dr. Steve Burian

    Project Description Urban water infrastructure

    suffers from a lack of

    knowledge of the pressure

    throughout the pipelines. This

    problem could be solved by

    remote wireless pressure

    sensors placed throughout the

    pipeline. However, getting

    power and data to and from

    pressure sensors inside water

    pipelines is an unsolved

    challenge. The goal of this

    project is to design and

    develop a system for

    powering and getting data from a pressure sensor inside an urban water pipeline.

    In one possible implementation, we envision an ultrasonic power and data

    transmission system to transmit power and data through the metal wall of the

    pipe. A piezoelectric ultrasonic transmitter could be attached to the outside of the

    pipeline. A matching ultrasonic receiver and pressure sensor would be attached

    to the inside of the pipeline. The transmitter would power up the sensor, which

    would then take a reading and transmit the data back. The team would need to

    design the piezoelectric transmitter and associated electronics. The team will also

    design the ultrasonic receiver and integrate it with a commercial pressure sensor

    and associated electronics enabling multi-function (power and data)

    transmission.

    Although we have envisioned an ultrasonic power transfer system with an active

    (i.e. powered) pressure sensor, the senior design team may come up with other

    possible solutions to the problem, which would be welcome.

    Project

    Objectives/Desired

    Outcomes

    1. Demonstrate power transmission through the wall of a steel pipe. 2. Demonstrate data transmission through the wall of the steel pipe using the

    same system.

    3. Demonstrate a full operating system taking pressure measurements using only transmitted power.

    Project Number 7

    Project Name Enhanced design of an incendiary (fire) wind tunnel

    Faculty Name Professor Eric Pardyjak ([email protected]), Professor Rob Stoll

    ([email protected]), and Dr. Kochanski (Atmos. Sci.)

    ([email protected])

    Project Description During the 2017-2018 academic year, a

    student team designed and built a tilting

    wind tunnel capable of safely modeling

    and visualizing laboratory-scale

    wildfires as part of an NSF funded

    interdisciplinary wildfire spread project.

    The wind tunnel will ultimately be used

    as an education tool for illustrating the

    impacts of various affects on smoke and

    fire propagation in an idealized setting.

    This year, a senior design team will

    modify the tunnel to include the ability to

    demonstrate the impact of a range of

    fuels, fuel distributions, and wind

    conditions. Furthermore, it is expected

    that this year’s team will add

    instrumentation that will allow fire

    temperatures, rates of spread, and winds

    to be quantified. Funds will be provided

    for the purchase of materials and supplies

    to support the project.

    Project Number 8

    Project Name Dynamic Manual Wheelchair Braking System

    Faculty Name Andrew Merryweather ([email protected]) & Dr. Jeffrey Rosenbluth

    Project Description The Dynamic Manual Wheelchair Braking System is a hands-free, dynamic, and

    static braking system that provides manual wheelchair users with an

    unprecedented level of braking control. The system does not change the look of

    the chair and enables users to remove the parking brake feature installed on most

    manual wheelchairs.

    Project

    Objectives/Desired

    Outcomes

    Concise technical summary:

    We propose a novel wheelchair braking system that will allow for both static

    and dynamic braking while utilizing much of the existing wheelchair hardware.

    This system will be operated using the internal rotation of the forearms, allowing

    SCI users with injuries up to C6 to operate without needing hand function. Brake

    operation will be performed using a modified armrest and armrest receiver, and

    in most cases the existing armrest mounting hardware can be used.

    Braking force will be achieved using a standard bicycle brake pad that will apply

    a variable force to the wheelchair rim, creating friction. The brake pad position

    and rotation would be adjustable to allow for optimal placement on a variety of

    different wheelchair rims and frame from different manufacturers. Once

    positioned properly, set screws can be tightened to lock the brake linkage in

    place.

    The main pivot point would be a female receiver located towards the rear of the

    wheelchair. This receiver could be a drop-in replacement for the original armrest

    receiver, and ideally would utilize the same mounting hardware. This receiver

    could also be the same inner diameter as the original, allowing for backwards

    compatibility. The receiver would utilize a vertical locking mechanism to ensure

    the armrest/brake couldn’t easily pull out of position once inserted. The simplest

    such mechanism would be a spring detent that required a certain amount of

    vertical force to insert/remove the armrest from the receiver, though other means

    will be investigated. The locking mechanism must obviously allow for a

    rotational DOF to enable braking.

    Alongside the vertical lock, the receiver will be designed in such a way as to

    limit the range of motion on the rotational axis. This could be achieved using a

    pin/slot mechanism between the armrest and receiver. The ROM would be

    limited on armrest internal rotation by the brake pad intersecting the rim, but

    external rotation would need to be limited by this other means. The system will

    also utilize a light torsion spring to return the armrest/brake to this maximum

    Additionally, for static braking, a mechanism will be developed to lock the pads

    against the rim in a “parking brake” position. This function will provide

    additional safety during stationary activity on uneven terrain and during

    transfers.

    The armrest itself will consist of two pads – one horizontal to provide traditional

    armrest support for elbows and forearms in a resting position, and one smaller

    vertical pad on the inner front portion of the armrest to allow braking force to

    be applied by the forearms. The position of this vertical pad would be adjustable,

    allowing the system to fit any arm length in the optimal position.

    Project Number 9

    Project Name Solar-Powered Thermo-Chemical Energy Storage

    Faculty Name Professor Kent Udell ([email protected]) Project Description Thermo-Chemical batteries can store thermal

    energy and then use it at a later time for either

    heating or cooling applications. Through

    research funded through ARPA-E, we have

    learned the secrets of packaging ammonia-

    saturated magnesium chloride in a way that

    should provide enhanced heat and mass

    transfer performance in a configuration well-

    suited for solar recharging. And the

    temperatures produced are high enough to

    heat an oven. We now need to find a good way

    to recharge the thermal battery with solar

    energy. That is the aim of this project.

    The team will design and construct the solar

    energy concentration and collection system,

    ammonia condensers, the magnesium

    chloride salt cooling system and liquid

    ammonia holding system. A one ton air

    conditioning target is sought. Evaporators for

    refrigeration or air conditioning, and heat

    exchangers for air, water and oven heating

    will be provided.

    Project

    Objectives/Desired

    Outcomes

    1. Design and produce a high performance cylindrical solar absorber including the spectral surface coatings and evacuated tube vacuum sealing system

    Project Name MEK Wind Turbine

    Faculty Name Prof. Meredith Metzger ([email protected])

    Project Description At the University of Utah, we are

    exploring the feasibility of harvesting

    wind energy in the urban/suburban area

    through the use of small vertical axis

    wind turbines, as shown in Fig. 1. This

    senior design project will focus on the

    implementation of a quarter-scale vertical

    axis wind turbine that will be mounted on

    the rooftop of the Mechanical

    Engineering Kennecott (MEK) building

    and used for the purpose of performance

    testing. The turbine blades and support

    frame have already been fabricated by a

    prior senior design team, following the

    design guidelines of Nguyen and Metzger

    (2017). The blades are comprised of

    composite materials to keep the moment

    of inertia of the turbine as low as possible,

    allowing the turbine to respond quickly to

    changing winds in order to capture the

    maximum amount of energy available in

    the gusty wind conditions characteristic

    of Salt Lake City. An illustration of the

    turbine is shown in Fig.2. The main tasks

    to be accomplished this year are: (i)

    design the shaft/bearing system including

    balancing, (ii) implement an electrical

    breaking system for high wind situations,

    (iii) implement a generator to recharge a

    battery, (iv) perform laboratory tests to

    validate the design, and (v) install a fully-

    functional prototype on the rooftop of the

    MEK building. The proposed installation

    location is shown in Fig. 3.

    Project Name Granular Application System For UAV

    Faculty Name Prof. Meredith Metzger ([email protected])

    Project Description The Salt Lake City Mosquito Abatement

    District (SLCMAD) controls the population

    of mosquitoes to protect public health and

    increase the quality of life for residents of

    Salt Lake City. Most of the mosquito control

    efforts are conducted against juvenile

    mosquitoes which live in water. Many of the

    prime mosquito habitats are freshwater

    marshes around the Great Salt Lake. Thick

    vegetation found in these wetlands makes it

    hard for liquid pesticides to reach the surface

    of the water, so SLCMAD uses granular

    formulations for many pesticide

    applications. Traditionally these pesticide applications to wetlands have been

    done on foot, by ATV or with a large tracked vehicle. These methods are labor

    intensive, cause heavy wear to equipment and can damage the environment.

    SLCMAD recently purchased a DJI AGRAS MG-1S unmanned aerial vehicle

    (UAV) to make pesticide applications. This UAV comes with a system to apply

    liquids but not granules. This senior design project will focus on the design and

    fabrication of a granular application system for the MG-1S.

    Project

    Objectives/Desired

    Outcomes

    1. Design and fabricate a fully functional prototype of a granular application system for the MG-1S UAV.

    Project Number 14

    Project Name Andrology Clinic in a Box

    Faculty Name Professor Bruce Gale ([email protected]) & Alex Jafek ([email protected])

    Project Description Our lab has recently developed technology capable of preparing semen samples

    for intrauterine insemination (IUI). The central element of this platform is a

    microfluidic spiral channel which uses Dean flow to separate particles based off

    of their size. At this point, one of the main hurdles to commercialization is the

    development of an instrumentation system capable of processing the device

    through the spiral channel in an automated way. Last year, a Capstone team

    successfully developed a preliminary prototype of the design demonstrating

    integration of temperature control, pumping, and valving. This year, we are

    seeking to recruit another Capstone team to advance the instrumentation system

    even further by building upon the successes of the last team.

    Students on this Capstone team should have an interest in product design and an

    ability to think creatively about mechatronic integration. There are fundamentally

    three shortcomings with the existing platform that we would want to see solved

    by a Capstone team:

    1. An ability to start directly from a sample cup (as opposed to preloaded in a syringe)

    2. A design that employs a replaceable cartridge design 3. An ability to employ our advanced protocol (which requires processing

    the unselected portion)

    Project

    Objectives/Desired

    Outcomes

    1. Functioning prototype that can be used in the clinic including temperature control, pumping, and valving that has the footprint of a printer.

    2. Demonstration of all critical performance metrics listed (start from sample cup, replaceable cartridge, integration of advanced protocol)

    Project

    Engineering Skills Mechatronic design (electro-mechanical design and programming)

    CAD and product design

    Rapid prototyping, manual machining, and/or CNC machining

    Project Number 15

    Project Name Realtime pest monitoring device for agricultural systems

    Faculty Name Professor Kam K Leang ([email protected]) and Professor Rob Stoll

    ([email protected])

    Project Description A wide range of agricultural pests (e.g., insects) have a significant impact on

    agricultural productivity both directly and indirectly as plant disease vectors (e.g.,

    means of transmission). Effective and sustainable responses to pests require

    knowledge of their location and activity levels. Unfortunately, most monitoring

    systems use manual pheromone traps (bug lures) which require the deployment,

    collection, and then counting of trapped insects. This process means data is both

    sparse spatially and in time. As a result to deal with the most impactful pests,

    agricultural managers typically take extreme measures (full field broad spectrum

    insecticide application) at any detection with negative consequences for both the

    pests and beneficial insects. The goal of this project is to develop a realtime

    pheromone trap to detect and trap male grapevine mealybugs. The challenges

    include the small size of the bugs (~1 mm) and their relatively poor flying

    ability. This project will construct a realtime trap prototype that can be deployed

    in agricultural fields to improve management decisions. Initial funds of $1K in

    addition to nuts and bolts funds will be provided to the team with additional

    possible for parts through the USDA if justified. While this is a prototype, the

    long term goal is to keep costs low enough to deploy multiple sensors in the field

    and to keep the device light enough to deploy using UAVs.

    Project Number 16

    Project Name Fast response fungal spore collection device for agricultural systems

    Faculty Name Professor Rob Stoll ([email protected]) and Professor Kam K Leang

    ([email protected])

    Project Description The primary transport mechanics for many fungal plant pathogens is the

    wind. Spores from fungal pathogen colonies are transported away from infection

    sites by unsteady (turbulent) fluid motions to new susceptible tissue (leaves). To

    better understand how pathogens spread through the air (and the associated

    propagation of diseases in plant systems), we need to be able to measure the

    concentration of spores at different points within the plant canopy. The goal of

    this project will be to develop a realtime airborne spore identification and

    counting device for use in agricultural systems. Currently, spore identification

    and quantification (counting) for airborne fungal agricultural pathogens is

    performed manually using a combination of traps (to sample) and laboratory

    analysis. A devices is needed that can take measurements of spores in the field in

    real time to vastly improve management decisions and enable the automation of

    management decisions (e.g., localized fungicide application). The device must be

    rugged enough to be deployed in harsh environments (i.e. agricultural fields). A

    successfully developed device will be deployed with USDA science collaborators

    in agricultural fields and tested against traditional impaction trap based methods

    (which require laboratory analysis). This project is perfect for a motivated team

    of 3-5 students with the expected design components that use students knowledge

    of fluid mechanics, automation and system design (mechatronics), and machine

    vision and learning techniques. Initial funds of $1K in addition to nuts and bolts

    funds will be provided to the team with additional possible for parts through the

    USDA if justified. While this is a prototype, the long term goal is to keep costs

    low enough to deploy multiple sensors in the field and to keep the device light

    enough to deploy using UAVs.

    Project Number 18

    Project Name L3 Technologies Industry Sponsored - Lead-Free Solder Project [Industry

    Sponsored Project - Pending]

    Faculty Name Pending, Temporary student contact: Holly Alvarez ([email protected])

    Project Description

    Most products that require any type of electric conduction, require soldering.

    Leaded solder has been commonly accepted as the most reliable soldering

    material among industry. Therefore, L3 Technologies currently uses leaded solder

    for all manufacturing applications. However, as part of the RoHS (Restriction of

    Hazardous Substances) directive, L3 has initiated a project to replace all leaded

    solder processes with a lead free solder. Doing this will provide a safer

    environment for product manufacturing and a safer end use product for

    consumers. Many companies have already switched to lead free solder. However,

    most companies do not produce military grade products that must withstand

    rigorous testing and meet military specification requirements. To convert to lead-

    free solder the following must be addressed.

    Structural integrity of solder joint

    Aesthetic appearance of solder joint

    Lifespan of solder joint

    Designing for high conduction requirements

    Thorough quality testing

    Soldering production cost This project requires all team members to be security approved upon the start of

    the project. This project will provide team members with valuable experience

    working with senior level engineers and management at L3 and exposure to the

    L3 work environment.

    Project

    Objectives/Desired

    Outcomes

    1. Develop detailed understanding of L3's soldering applications and goals 2. Create a design of experiments to formulate a No Clean, lead-free soldering

    paste that meets product requirements

    3. Test formulated solder using numerous test methods 4. Analyze test data to determine most optimal soldering process that aligns with

    ISO requirements

    5. Internally published test report and white paper 6. Implement new soldering process within manufacturing and operations

    Project

    Engineering Skills Problem solving: The process will need a formulated lead-free soldering paste

    that meets L3's application as described.

    Electrical: To develop a working process, understanding electrical conductivity and routing will be useful.

    Test: Know how to carry out a properly organized experiment to eliminate variability and error. Prior DOE experience is preferred. Various tests will be

    performed for each test sample.

    Technical writing: Our team will be publishing a thorough test report and white paper.

    Manufacturing: This soldering solution will be implemented throughout L3 manufacturing and operations. Training can be provided.

    Desired Team Size 4-6

    Project Name Modular Manipulator with 6 Degrees of Freedom for Drone [Student Proposed

    Project – No longer accepting new member]

    Faculty Name Dr. Mark Minor ([email protected])

    Primary contacts: Ryan Kitchen ([email protected]), Klaus Griessmann

    ([email protected])

    Project Description For many industries, there is constant routine maintenance that must be done.

    However, this routine maintenance is not always in the safest or most convenient

    spots. For example, workers in the powerline and wind farm industries work

    around many hazards for oftentimes simple repairs. We propose that these

    dangers and time consumers can be mitigated through the use of drone

    technology.

    This project will focus on the development of a manipulator, with 6 degrees of

    freedom, that will have a modular head. The modular head will make it so a

    different tool type can be created and attached to the arm, depending on what

    tasks need to be done. The heads that we will focus on for this project are a soft

    grabber and an impact drill. We will also consider a soldering iron and a precision

    cutter.
