Multiline Phone Monitor
This article describes a phone monitor which assists sightless people in
answering a multiline phone easily.
This monitor is a separate stand-alone unit independent of the telephone and
can be used with any phone having lighted buttons.
The multiline phone monitor is contained in a case 10 adapted to mate with
the phone and uses photosensors 12 in sensing the light 11 on a multiline phone.
The sensors activate remote amplifiers (contained in a separate power box),
which in turn send a signal to the solenoid 15 that corresponds to the line in use
on the phone. Each button on the phone has a sensor and solenoid. When the
light on the phone is lit, the core of the solenoid 13 is activated and protrudes
through 14 on the phone monitor. The sightless person then feels the core, and
can press the corresponding button and answer the correct phone line easily.
This could be expanded to larger phone systems with different sensors and
