Design and implementation of a computerised remote alerting system for disabled people

We describe a remote alerting system for disabled people. The purpose of the system is to enable a monitored person to easily request medical assistance by pressing a single button on a wearable transmitter device. It should be noted that the handicapped person does not need to take any other action, such as picking up the phone. Upon triggering, the system is capable of automatically alerting the medical personnel, indicating the location of the alert using a digital transmission system or a speech synthesis module. Our system operates using primarily telephone links of any kind (PSTN, GSM, etc.). The system is intended for use by older or disabled people living alone, who may suddenly require immediate medical assistance, in particular, the people with physical disabilities and cardiovascular diseases.
