Process Improvements Of Cilantro Harvesting With Ergonomic Considerations, Eric Penningroth, Branden Shimamoto Dec 2014

Process Improvements Of Cilantro Harvesting With Ergonomic Considerations, Eric Penningroth, Branden Shimamoto

Industrial and Manufacturing Engineering

The problems presented by Talley Farms to the team were a lower than desired cilantro harvesting capacity and work health pertaining to lower back problems. The project objectives were to address and improve upon both of these objectives. To increase harvesting capacity, a simulation model was created using standard times from time studies. The simulation model helped to compare the different harvesting methods as well as the effect of the utilization of the on-site manager. The throughputs between each of the models were analyzed. To address ergonomic concerns, a work sampling study was conducted and it was determined that kneeling …


A Method To Develop Neck Injury Criteria To Aid Design And Test Of Escape Systems Incorporating Helmet Mounted Displays, Jeffrey C. Parr Sep 2014

A Method To Develop Neck Injury Criteria To Aid Design And Test Of Escape Systems Incorporating Helmet Mounted Displays, Jeffrey C. Parr

Theses and Dissertations

HMDs are becoming common human-machine interface equipment in manned military flight, but introducing this equipment into the overall aircraft escape system poses new and significant system design, development, and test concerns. Although HMDs add capabilities, which improve operator performance, the increased capability is often accompanied by increased head supported mass. The increased mass can amplify the risk of pilot neck injury during ejection when compared to lighter legacy helmets. Currently no adequate USAF neck injury criteria exist to effectively guide the requirements, design, and test of escape systems for pilots with HMDs. This research effort presents a novel method to …

Ergonomics Study Led Lighting Assembly, Marylin Glass-Angeles, Nathan Christensen, Josef Imesh, Lorena Peña, Natalia Matos Apr 2014

Ergonomics Study Led Lighting Assembly, Marylin Glass-Angeles, Nathan Christensen, Josef Imesh, Lorena Peña, Natalia Matos

Research and Creative Activities Poster Day

The current assembly process of the LED Lighting product line at Landscape Forms (LF) combines high force exertion, motion repetition and an uncomfortable posture. Therefore, Industrial Engineers overseeing the manufacturing of these products raised a concern for their workers health and were interested in identifying injury risks related to the current methodology as well as opportunities for the reduction of such risks.


Injury Prevention With Physical Therapy, Karen Kott, Margaret F. Lemaster Jan 2014

Injury Prevention With Physical Therapy, Karen Kott, Margaret F. Lemaster

Rehabilitation Sciences Faculty Publications

(First paragraph) Ergonomics is the study of human performance (positioning and movement) and workplace design, such as equipment, ambience, and placement. The purpose of ergonomics is to maximize productivity by increasing safety, improving work quality, reducing operator fatigue and discomfort, and decreasing the risk of work -related musculoskeletal disorders (MSDs).1-3
