All About Engineering

 JOKE OF THE WEEK:

Theory is when you know everything and nothing is working. Organization is when nothing is working and everyone knows why. Practice is when everything is working and no one knows why.

QUOTE OF THE WEEK:

“Scientists dream about doing great things. Engineers do them.”

-- James A. Michener
U.S. novelist and short-story writer, 1907?-1997

ENGINEERING FACT OF THE WEEK:

A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing. The cochlear implant is often referred to as a bionic ear. Unlike hearing aids, the cochlear implant does not amplify sound, but works by directly stimulating any functioning auditory nerves inside the cochlea with an electric field. External components of the cochlear implant include a microphone, speech processor and an RF transmitter. An RF receiver is implanted beneath the skull's skin. The transmitter has a magnet by which it attaches to another magnet placed beside the receiver. The receiver relays the incoming signal to the implanted electrodes in the cochlea. The speech processor allows an individual to adjust the sensitivity of the device. The implant gives recipients additional auditory information, which may include sound discrimination fine enough to understand speech in quiet environments. Post-implantation rehabilitative therapy is often critical to ensuring successful outcomes.
