A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits, repeating the signal coming in from one circuit and re-transmitting it to another. Relays were used extensively in telephone exchanges and early computers to perform logical operations.
A type of relay that can handle the high power required to directly control an electric motor or other loads is called a contactor. Solid-state relays control power circuits with no moving parts, instead using a semiconductor device to perform switching. Relays with calibrated operating characteristics and sometimes multiple operating coils are used to protect electrical circuits from overload or faults; in modern electric power systems these functions are performed by digital instruments still called "protective relays".
Lori Jones, more commonly known as Lolo Jones, (born August 5, 1982) is an American track and field athlete who specializes in the 60 and 100 meter hurdles. She won three NCAA titles and garnered 11 All-American honors while at LSU. She won indoor national titles in 2007, 2008 and 2009 in the 60 m hurdles, with gold medals at the World Indoor Championship in 2008 and 2010.
She was favored to win the 100 m hurdles at the 2008 Beijing Olympics, but she tripped on the penultimate hurdle, finishing in seventh place. She went on to win silver at the 2008 World Athletics Final. Jones is the American record holder in the 60m hurdles with a time of 7.72.
Lolo Jones was born on August 5, 1982. In her youth, Lori "Lolo" Jones had a series of obstacles to overcome. Jones attended eight schools in eight years while her single mother, Lori, often held down two jobs to support her family of six. Lolo's father spent most of her childhood in the Air Force or later in state prison. In third grade, the Jones family settled in the basement of a Des Moines Salvation Army church. During the summer when day camps were offered at the church, Lolo would wake up early to avoid being teased by other kids if they found out she was living in the basement.
You can hear it in the street, see it in the dragging feet
The word is gettin' out about control
Spies they've come and gone, the story travels on
The only quiet place is inside your soul
From tree to tree, from you to me
Travelin' twice as fast as on any freeway
Every single dream, wrapped up in the scheme
They all get carried on the relay
Relay, things are brewin'
Relay, something's doin'
Relay, there's a revolution
Relay, relay
(Hand me down a solution, yeah)
Pass it on, come on, a relay
Someone disapproves, what you say and do
I was asked to see what I could really learn you
Don't believe your eyes, they're tellin' only lies
What is done in the first place don't concern you
From tree to tree, from you to me
Travelin' twice as fast as on any freeway
Every single dream wrapped up in the scheme
They all get carried on the relay
Relay, things are brewin'
Relay, something's doin'
Relay, there's a revolution
Relay, relay
(Hand me down a solution, yeah)
Pass it on, pass it on, pass it on, hey you, pass it on
We're on the relay, get a movin'
Get on a movin' on
The relay, the relay
