Ear Infection Detector

Ear Anatomy

Ear Infections: Detectable Symptoms

Normal

Infected: Redness & Stiffer Ear Drum

Our Detection Approach

• Use optical sensor to detect redness.

• Use acoustic sensor to detect stiffened ear drum.

• Use infrared sensor to measure temperature.

• Use electronics to correlate three different measurements and determine likelihood of infection.

EarCheck works by injecting small jet of air and analyzing response: Only one sensor

Competition: EarCheck checks for ear infections

Competition II: Braun Thermoscan: Thermometer only, not ear infection detector. Probably works with infrared detector.

Our Product

• Approach I:– Combine our new optical technology

– With existing acoustic sensor and ear thermometer

– Perform correlation electronically

– Obtain more accurate reading

• Approach II:– Use optical technology only for a simple non-invasive approach (no

air jet)

– Requires simple photo-diode red-light detector

– Less expensive

• House both approaches in otoscope-like instrument.
