Why A Mobile Alert System? • Currently, can only access call button from room – Cell phone can be difficult for some • Expedite search for missing resident • Let bystanders know resident needs help – Especially those with speech impairment • Immediate notification of tipped wheelchair

Possible Solutions – Tip Alert • Gyroscopic sensor – Already available to us – Complex calculations required • Accelerometer – Similar calculations required • Tilt Switch – Two options – Comus International and Arduino model – Comus International more likely to detect tip

Possible Solutions – Help Button • Push button – Not adaptable • Capacitive touch sensor – Small strip – too small – 3 D printed button • Doubles as storage for coil

Possible Solutions – Help Sign • Corrugated plastic with individual LEDs – Light not vibrant enough • Clear acrylic sign with LED strand – Light shines through brightly – Framed for damage protection • Two wording and layout options considered

Final Design • Press button or tip wheelchair to send email notification to staff • Notify bystanders by lighting sign • Controlled by Arduino Uno • Powered by 12 V drill battery

Tilt Switch • Wheelchair flips greater than 50˚ – Doesn’t need to be perfectly horizontal • Open or closed – No calculations or complex code

Help Button • Capacitive touch • No need to apply pressure • Can be placed anywhere • Any size or shape • Can be designed to meet various needs

Help Sign • Highly legible and eye-catching • Has resident’s name to get more personalized help from members of the public • Attached with Velcro for easy removal or repositioning

Email Notification • Manually by button or automatically by tip • Sent to a dedicated account – Easily distinguish from other personal or work email • Contains resident’s name and location • Wi-Fi in building, 4 G outside

Power Source • • 12 Volt drill battery Easy to remove and reinsert Easy and safe to use charger Can be charged overnight

Future Development • Combine with the location tracking Integrated Wheelchair Positioning System – Reduces hardware • Wi-Fi configuration • Power source research – Life of drill battery – More affordable batteries • Mobile application
