All Out Lights Views
Lights Out is an electronic game, released by Tiger Toys in 1995.[1] The game consists of a 5 by 5 grid of lights. When the game starts, a random number or a stored pattern of these lights is switched on. Pressing any of the lights will toggle it and the four adjacent lights. The goal of the puzzle is to switch all the lights off, preferably in as few button presses as possible.[1]
There are nearly 200,000 lights in Chicago using sodium vapor lamps that illuminate both arterial and residential streets. Many of these lamps have been equipped with photocells rather than clock timers in an effort to conserve energy. Street lamp outages should be reported immediately to the citymrs"s 311 customer service request line; this same number also should be called of tree branches block the light from street lamps creating shadows on the street or sidewalk. In 2007 all of the Chicagoers"s arterial street light fixtures were relamped and cleaned. Relamping the residential street lights are scheduled for early spring of 2008. Under Mayor Daleyers"s leadership and various city programs new residential street lighting systems have been installed on over 1,600 blocks throughout the city. The systems include aluminum poles, brighter roadway fixtures and pedestrian access fixtures.
A seemingly innocent string of Christmas lights actually has many tricks up its sleeve, most of which won't be discovered by the household tree decorator until it's too late. Christmas tree lights really do multiply in the box, and they spend most of their days braiding themselves together in Gordian knots. The final act of Christmas light cruelty is the all or nothing lighting trick. Depending on the design, an entire string of Christmas lights can indeed fail if only a single bulb burns out or comes out of its socket. The reason for this has to do with the nature of electrical circuits and the Christmas bulbs which depend on them.
There are two basic electrical wiring scheme used to form a string of Christmas lights. One scheme, called a series uses a single wire connection between bulbs to light them all. The electricity from the household outlet flows down that single wire and through the first Christmas tree bulb. That bulb glows as a certain amount of electrons escape into the bulb. The rest of the electricity continues to flow through the wire to the next bulb in the series and so on until the string of Christmas lights is either connected to another string or the electricity flows back into the negative side of the outlet.
