Elixir Report – Techfest 2010

A report on Elixir:

http://www.techfest.org/initiatives/prayaas/elixir/

Reviewed:

  1. User Friendly Helmet
  2. LivoSensor
  3. MultiAccess Incubator

User Friendly Helmet

Team: NIT Surat

Addressed Needs:

  • Heat-strokes are common for warm indian climates. Cited heat discomfort as the primary cause of people not wearing driving helmets.
  • Hence reducing safety of drivers and co-passengers.
  • Bulky, inconvineant to carry around everywhere.
  • Inexpensive solution to an important problem at Rs. 150/- extra cost.

Strong Points / USP:

  • Comfortable “joyous ride”
  • Cooling pad installed:
  • Cooled externally via refrigration
  • lasts 2-3hrs.
  • Foldable, hence portable.
  • About 1/3rd of original size when folded.
  • Sweat absorbing layer; Washable

Weak points / Aspirations and Gaps:

  • Modular design – sleek but makes it very vulnerable to impact damage. Hence putting the user at hazzordus risk. Defeats the primary purpose of safety.
  • No Impact Testing of equipment was performed.
  • Clips, screws etc. inconvineant and time-consuming to remove/fold and install back again while.
  • Removable parts not a good design idea. Prone to loss.
  • No temprature controller proposed in the design. I think resonable maintenance of temprature is essential. Too cold/uncontrolled temprature might be more damaging than comforting.

Applications In BioMedical Engineering

A System’s Perspective: Computer Science, Embedded and Control Systems

Control Systems and Theory:

  • Understanding and thus modeling of human physiology and pathology.
  • Leading towards applications like controlled medication like drug delivery.
  • Factors like rate and dosage could be controlled.

Computer Science and Embedded Systems:

Integration of computer science with embedded systems has lead to many applications within medicince and healthcare.

  • Machines like X Rays, CT Scan, MRI help diagnose a disease/condition rapidly.
  • While others like defibrilators, pacemakers, dialators and cathetors help keep a patient under check and improve the response time of a doctor.
  • Hapitics enabled Surgical Simulators are a boon for providing high risk Medical Operations and Training today.
  • Visualization Systems that enable 3D Reconstruction of human body from CT Scan, X-Rays, MRI, etc, powered by computer graphics and imaging technology has greatly enhanced understanding & analysis of medical students and doctors alike.
  • Applications like Telemedicine and Telesurgery rely on backbone of Internet and Communications Infrastructure.
  • I envision integration of mobile and healthcare devices in future thus enabling the common man to keep himself under check while on the move.
