A portable, low cost, stand-alone device which could be operated either by battery (9 V) or adapter power. The device fits comfortably to a human mouth and uses his/her breath to control switches with definite functionality. The device is highly adaptable and user friendly and could be customized as per the ability of the physically handicapped to ‘blow’ air. The device has multi mode of operation as per the residual ability of the patient so as to operate many environment control units.

Areas of Applications:

Rehabilitation of severely handicapped people who have the ability to ‘blow’ as their residual ability.

Advantages: Low cost, portable electronic communication aid.

Stage of Development: Lab model and prototype completed.

Inputs required:

Electronic Components (Bread Boards, PCB’s, Resistors, Transistors, Relays, IC’s etc), Soldering Station, PCB Fabrication Unit, Testing Workbench (30 MHz CRO, Function Generator, Power Supply etc.), Workstations with Relevant Software for Programming & for PCB designing.

Economic Data: Rs. 15,000/- (Approx).

Transfer forms: Technology transfer through FITT, IIT Delhi.
