Overview of Status of Analysis, Design, Fabrication, Tests, etc.
· Analysis:
o Identified areas for analysis
§ Fluid analysis of syringe, tubing etc.
§ Pressure/force analysis on sensor
§ Linear motion analysis on syringe pump
o Design
§ Concept stage
o Fabrication
§ NA
o Tests
§ Concept stage
Accomplishments from Previous Week
· Researched theory surrounding pressure transducers and developed search criteria
o Low hysteresis
o High repeatability
o Frequency response suitable for real time readouts
· Have held concept meetings
o 3 main modules identified
§ Syringe Pump w/ user interface and display
§ Pressure sensing module
§ Hand held flow adjusting device
· Defined constraints for pressure sensing
o Sensor must not be in contact with the fluid at all to avoid possible contamination
· Brainstormed pressure sensing with Isaiah and Steve Roberts
o Load cell concept
o Tube strain concept
Goals for Next Week (list names after each item). Use specific and measurable objectives
· Risk reduction presentation [TEAM]
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments
· “Pressure sensor cannot be in contact with fluid at all”
o Met with Steve Roberts and Isaiah to brainstorm ways around this
Instructor Comments from Last Meeting and Actions Taken to Address these Comments
· Terminology
o Device previously referred to as “Handheld toggle device” is now known as Handheld Flow Variation Device
