31.   In conventional hearing aids, known as analog models, the sound is converted to an electrical signal but never to a digital one.

32.   It is the catch-all name for various disorders characterized by disturbed electrical signals from the brain that may cause convulsions.

33.   Nerve cells are able to transmit electrical signals because of channels, embedded in their membranes, that maintain an electrical imbalance between the nerve fiber and its surroundings.

34.   Myelin acts as an insulator for electrical signals.

35.   Once he has recreated the scary heartbeat, he can pinpoint the area where electrical signals go awry.

36.   Once such condition is known as heart block, in which the body fails to produce the small electrical signals that regulate the heartbeat.

37.   Otherwise, the sensor will drain the electrical signal just like an ECG contact sensor does, says Prance.

38.   Pacemakers are devices that send electrical signals to heart muscles to maintain a normal rhythm of heart beats, and doctors have implanted them for nearly half a century.

39.   Rather than converting the mechanical energy to electrical energy and dispersing it, the piezoceramic plate converts the electrical signal back to mechanical energy.

40.   Since a telephone carries information in the form of electrical signals representing sound waves, the quality of transmission can vary widely from place to place.
