Project Name: Incorporating Pain Alleviation Mechanism into CMC Arthritis Splint

Group Number: 14

Group Members: Reith Sarkar, Puneet Kumar, & Keshav Kohli


Current status of project:

1) Controller Circuit

- essentially complete

- figure out necessity of potentiometer with LCD

- optimize resistor choice for greater thermal resolution

- choose either optocoupler or power transitor

- depends on current need of heating element

- redesign PCB board to save space/cost

- choose components/manufacturers

- find property spreadsheets and pricings


2) Thermal Heating Element

- design - in progress

- material choice - in progress


Work planned for next week:

- complete all CAD renderings

- design housing (sketch) first

- 1ST PRIORITY

- NEED TO DETERMINE THERMAL UNIT BEFORE PROCEEDING - ASAP



Anything needed from client or TA or instructor to continue work:

- submit psuedocode to Professor Klaesner for brief review to ensure completeness (submit by Wed)

- client Tiffany Harmon: TBD

• preliminary presentation
  
  
• met with client (Friday 9/20):
  
  
• informed client of current progress and goals
  
  
• clarified certain metrics with client
  
  
• therapy accessory will be used in:
  
  
• 15-30min intervals, 4x a day for heat application
  
  
• 10 min intervals, 6x a day for cold applications
  
  
• L-Code is high-demand requirement
  
  
• If accessory is classified under an L-Code, the cost of the accessory can be subsidized by insurance providers, saving the consumer money.
  
  
• potential code: L3807-WHF-0 static
  
  
• total cost <$250; cost to customer <$100
  
  
• client will send information concerning durability metrics and additional L-Code information
