Smart sensors designed for toolchair tip- over definection employ a combination of microelectomechanical systems (MEMS) that measure motion, orientation, and external nal forces.

Preventive Measures Enabled by Sensors

Once a potential tip- over is decinted ted, thee system can activate a range of responses - some passive (warnings) and some active (mechanical interventions). The choice of intervention depends on thee sevity of thee the threat, thee type of wheelchair, and user preferences.

Audible Alarms andVisual Warnings

Simple but effective: a loud beep or voice alert (quite quite; Please lean back quentit;) gives the user impedate feeback. The alarm tone can vary by direction of risk - a high- souted tone for reclard tip, a lower tone for lateral tip. Some systems pair audity warnings with flashing LEds on thee joystick or armrest.
