ENSC-40 Incentive Spirometer

Team Members: Gage Bockenstedt, Jaspreet Kaur, Yuchen Huang, Joshua Santiago
Faculty Advisor: Shane Pacini
Sponsor: Lung Technologies LLC
Following many upper abdominal surgeries, there is an increased risk of pulmonary (relating to the lungs) complications. A device called an “incentive spirometer” is used patients to perform exercises with the intent of increase lung volume and reducing post-operation complications.
Project: Design, build, test, and characterize an improved incentive spirometer system that allows doctors to easily track more diagnostic information about patient use of this piece of medical equipment.

ENSC-41 Pick & Place Technology Trial

Team Members: Ethan Higa, Dylan Brown, Jovan Koledin, Jason Dhanota
Faculty Advisor: Chris Nicol
Sponsor: Kaiser
Full automation of a manufacturing process in most cases requires the automatic loading and unloading of the raw and processed materials respectively. This requires that these materials be adequately characterized, including size, position, and orientation so that material-handling equipment can accurately transport the material without damage or operator intervention.Kaiser’s Trentwood Rolling Mill produces aluminum plate for use in aerospace and demanding general engineering applications. The processing of these plates involves the use of multiple large industrial equipment centers to roll, thermally process, stress relieve, and saw the plates. At many of these centers, the plates are loaded and unloaded using overhead cranes equipped with vacuum lifting devices. Currently, the vast majority of these cranes are run either manually or in a semi-automatic mode that utilizes an operator for final positioning.Achievement of fully automatic operation of these cranes or future material handling equipment is dependent on the identification and implementation of technology that enables accurate determination of material size and position.
Project: Team will identify and evaluate potential technologies for the material size and position detection and trial them in a target operation of crane systems, evaluate results, and provide a preliminary engineering package for future implementation.

ENSC-42 Inclinometer & Speed Sensor Suite

Team Members: Elwyn Frailey, Luke Johnson, Ryan Leahy, Kevin Wolff
Faculty Advisor: Vladimir Labay
Sponsor: Orebaugh Ent. Ltd.
Development of a low-cost inclinometer and speed-measurement device that is able to detect out of level conditions as velocity changes. The device should have primary rechargeable cells as well as a bypass to allow a secondary power supply to be used. The device will have flashing LED indicators providing indication of an out of level condition. The intensity of the LED’s must be sufficient to be seen from a distance. The electronics must be developed from ultra-low cost components and circuitry, industrial grade, must be shock and vibration resistant and maintain long reliability for life. Design must only have one printed circuit board and be low profile and as dense as possible to minimize the overall size.

ENSC-43 Helical Antenna Array Feed Network

Team Members: Christopher Chock, Joshua Sonn, Michael Erickson, Colin Guy, Jared Marshall
Faculty Advisor: Bob Conley
Sponsor: SARL (Smart Antenna Research Lab)
Helical antennas have the unique ability to provide omnidirectional circular polarization. Combinations of these elements can provide any possible polarization, based on the signal processing. Developed and developing networks consists of printed circuit boards which need to provide a signal to the antenna elements, as well as structural integrity for the helices. Several attempts have been made to provide a signal to the antennas, the most functional of which is a coaxial cable feed. Unfortunately coax cables are high cost, so a PCB design is preferred which would make the technology more accessible.
Project: Research, design, analyze, prototype, and test a feed network (electrical paths use to deliver signal) to a helical antenna array by using the technologies associated with printed circuit board design in order to lower the costs associated with traditional coaxial cable feeds. This interdisciplinary project will have notable focus on electromechanical modeling as well as design for manufacturability.

ENSC-44 Distribution Line Lateral Integrity Detection System

Team Members: Joci Anderson, Matthew Gauss, Andrew Thompson, Rhys Williams
Faculty Advisor: Meirong Zhang
Sponsor: Avista
Avista is working hard to develop strategies to mitigate wildfire risk on their distribution and transmission systems. As a part of this process they have identified protection settings that can be used to reduce the total amount of energy released when a fault occurs on the system. The trade-off for this scheme is that fuses will not blow when there is a fault, and everything from the breaker out is shut off. As a result isolating the location of the fault becomes very difficult. This requires Avista to send out crews to inspect every inch of these distribution lines before re-energizing. This inspection process can take upwards of 20 hours on some of their longest lines.
Project: This team will attempt to develop a low-cost system that can be easily retrofitted on electrical distribution systems for quickly detecting fault locations to drastically reduce down-time while considering new strategies being utilized to mitigate risks of wildfires.

ENSC-50 Weld Testing/Inspection Equipment

Team Members: Carter Roth, Nicholas Ellison, Tyler Adams, Jacob Delger
Faculty Advisor: Andy Johnston
Sponsor: Keytronic
Keytronic produces a line of products that contain weld/solder joints that require inspection and system testing for their integrity. Welded and soldered joints have a variety of internal and system level issues that than effect performance of a product and typically need to be inspected and/or tested to verify quality. This inspection & test can often come at high cost especially when performed manually.
Project: The team will develop, prototype, and test a set of semi or fully-automated inspection equipment to perform tests on a welded or soldered product to verify its quality and performance. These tests will tentatively include thermal and vacuum integrity testing.

ENSC-60 Document Lift System

Team Members: Michael Ashe, Diana Garcia Diaz, Alexander Jones, Andrew Wilson
Faculty Advisor: Dan Harmon (Past)
Sponsor: Transitions (help4women.org)
The Transitions not-for-profit recently created a fire-safe room in the basement of one of their facilities to store required records such as contracts, personnel files, board documents. However, to get these documents down the stairs presents a safety risk. Despite recent stair improvements, a simple lift system to lower boxes would be advantageous and safer for all.   
Project:The team will attempt to design, analyze, build, and test a document lift system for the facility that can be safely operated by the Transitions administrators in order to reduce the risk of injury that may come from otherwise carrying documents up and down the stairs.
