71.   Optical transceivers are used in fiber-optic telecommunications networks to convert optical light pulses into electrical signals that can be processed and routed by computers.

72.   Scientists are pinpointing the neurochemicals that spark abnormal electrical signals and formation of some abnormal brain circuits and finding a slew of novel drug targets.

73.   The Lockheed Martin Anomaly Investigation Team suggested that the aerodynamic covering over the payload failed to come off properly because of a problem with an electrical signal.

74.   The problem with the electrical signal may have been caused by open circuits in redundant connectors, according to the findings.

75.   These channels are key to producing electrical signals that serve as nerve impulses and control muscle contraction, heart rhythm and hormone secretion.

76.   With the nerves cut, electrical signals from the ear cannot reach the brain, which causes deafness.

77.   When set off by Bobblitt using an external trigger, an electrical signal stimulates the muscles, stiffening them and forcing him into a standing position.

78.   When these light rays enter the eye, they are absorbed and converted into electrical signals by retinal nerves.

79.   With the nerves cut, electrical signals from the ear cannot reach the brain, causing deafness.
