Transcript: Members Land and Labor are Expensive Climate Change affects Farmers Worldwide The availability of fresh produce has high value The system would need to be: Customizable Safe Sustainable Efficient Thin Tray Hydroponics Thin tray Most common in retail, complicated, noisy, energy inefficient Deep tray Simple, cheap, safety concerns, low productivity Ebb+Flow Resilience, maintenance, moderate energy use, economics Overall: Ebb & Flow is the clear choice Global Food Crisis, we need more productive food systems, that use less water and land. American health crisis because of poor diets. Reduce the use of harmful plastic byproducts in packaging. We recommend the GardInn system's Ebb & Flow Hydroponics to solve all of these issues. Mike Gasasu McKenzie Gillit Things to Remember Our Solution: Hydroponics Questions? Three Types of Hydroponics Water Consumption Alternate wetting and drying, most resilient Reduced pumping costs caused this system to have the Highest Net Profit, even with increased Capital Costs of the timer. Less maintenance and noise than Thin Tray Our Team Water Usage Depends on productivity/plant type Plant growth/nutrient use Gas exchange Room ventilation, plant uptake/release of CO2 with light on/off Sizing and space requirements Size of each plant, number of racks, overall size of unit Economic Capital, energy use, productivity, IRR, NPV, NAB Reduced Productivity only one row because of safety concerns No water pump only aerator, lowest energy cost Not resilient because roots are always submerged Sizing The Problem Nicholas Cross Sam Carroll Mentors 1. Thin Tray 2. Deep Water Culture 3. Ebb & Flow Determining Alternatives Dr. Thomas A. Costello Cultivation BioEngineering LTD Our Findings Growth Rates First Idea: A Hydroponic Indoor Salad Bar Welcome to the GardInn Deep Water Culture Thank you for listening to our presentation! The Benefits: Productivity: Especially for NFT, Ebb & Flow More Product per Unit Space: 6 heads per sqft for traditional vs 16 heads per sqft Less Water Usage More Efficient Modeling Modeling Summary The team constructed many models to evaluate the economic, environmental, and social impacts of our three alternatives. Ebb & Flow Hydroponics Continuous pumping (noise & energy) Technical knowledge for nutrient flow, slope of the trays, pump & aerator sizing Not resilient because roots are always submerged Lighting

Transcript: Functional Requirements Solution 2 - Our client, Biomtec, wants to evaluate force measurements, not Torque Measurements. Mechanism to measure force of the quadriceps Background Conclusion -LC101-25 S-type Load Cell -Capacity: 0-500 lbs (0-250 kg) -Construction: 17-4 PH Stainless Steel -Operating Temperature Range: -40 to 93C -Excitation: 10 Vdc, 15 Vdc maximum -Output: 3 mV/V +- 0.0075 mV/V -Linearity: +- 0.03% FSO -Safe Overload: 150% of Capacity -Ultimate Overload: 300% of Capacity -Input Resistance: 350 +- 10 Ohms -Output Resistance: 350 +- 10 Ohms Physical Specs Purpose Physical Specs $$$ Cost Fulfills Client Need Load Cell provides good accuracy Up to 250 lbs load capacity Arcadio Salas Jr. Solid Modeling Biomtec + EHS + Simonis & Johnson Mentorship Proposed Design Jaime Carrillo Researcher Great Technology!? Hand-Held Dynamometer Strenghts In case load cell damage, device need to be dissasemble for replacement. A Compression-Tension Load Cell will be used in order to measure the force exerted on it. The patient's leg can be positioned at different angles. Once seated, the individual pushes his leg against the load cell. This output then goes through an analog to digital converter and finally translated into a Time vs Force graph. Variation on the force exerted by physician - Fixed hand-held dynamometer. The patient’s leg will exert a force on the hand-hand held dynamometer, which will be located on a pad that can be adjusted for different angles. - The hand-held dynamometer uses a Push-Pull mechanism. - Measure the torque exerted on about the knee. -The patient's leg can be positioned at different angles. - The main purpose of physical therapy after knee surgery is to recover the strenght of the Quadriceps. Failure to recover proper muscle strength will lead to a second injury! Physical Specs Physical Specs Solution 3: S-Load Cell Has been used for the past 40 years on Physical Therapy. Max Printz Structure Analysis Tension/Compression Load Cell - After a knee surgery, the strength of the quadriceps is reduced from 20% to 80%. - Quadriceps weakness can last up to one year after surgery. Physical Specs Physical Specs Not Reliable Not accurate Why? Solution 2 : Reaction Torque Sensor Hand-Held Dynamometer More than 4.5 million American are currently living with at least one Total Knee Replacement. Over 650,000 knee surgeries occur each year in the U.S. 54,000 go into a Second Surgery. Solution 3 Reaction Torque Sensor Futek Reaction Torque Sensor Rated output (RO): 2 mV/V nom Zero Balance: 1% of RO Bridge Resistance : 700 Ω nom Aluminum 17-4PH S.S Manual Muscle Testing (MMT) Solution 1 Load Cell The system will measure the force of the quardriceps femoris muscle of the patient while in a sitting position The system shall be able to measure forces at 30, 60, 90 degrees of knee extension . The system will target patients undergoing rehabilitation of the knee - Patients fail to follow rehabilitation OR -Doctors fail to designate the right physical therapy. Alberto Ferreiro Project Manager Selected Solution: Tension/Compression Load Cell Gantt Chart Based on Jim Harvey's speech structures Current Method to Evaluate Muscle Strenght Wrong Evaluation -microFET 2 has 99.5% accuracy -Load Cell Capacity 200lbs - Low threshold 0.8 lbs to 150 lbs. in 0.1 lbs increments (3.6N-660 Newton 0.4N increments) - High threshold 3 lbs to 150 lbs. in 1 lbs increments (13N-660 Newton 0.4N increments) Why!? Biomtec needs a device to measure the force of the quadriceps after knee surgery. Three designs: Hand-Held Dynamometer Reaction torque sensor chair Tension /compression load cell chair The tension /compression load cell was decided to fit the customer needs as well as obtaining the highest scores on the pugh chart analysis The Big Numbers (Market Potential) Solution 1 Design a mechanism device that measures the strenght of the quadriceps muscle to determine if a patient has recovered after knee surgery.
