Flashlight - Flashlight Household flashlight A flashlight, or torch (as it is known in the United Kingdom), is a handheld portable electric spotlight. A typical flashlight consists of a small electric lightbulb with associated parabolic reflector, powered by electric batteries, and with an electric power switch. The components are mounted in a housing that contains the necessary electric circuit and provides ease of handling, a means of access to the batteries for replacement, and a clear covering over the lightbulb for its protection. Although a relatively simple device, its invention did not occur until the late 19th century because it depended upon the earlier invention of the electric battery and electric light. The batteries in the first ones were of such short useful life that the common method.
Joshua Lionel Cowen - founded Lionel Corporation in New York City. Cowen had built his first toy train at age 7, attaching a small steam engine to a wooden locomotive he had carved. The engine exploded, damaging his parents' kitchen. Cowen also accidentally invented the flashlight in 1898, attaching small canisters containing batteries and light bulbs to a flower pot for the purpose of illuminating the plant. The invention was a flop, and Cowen sold the rights to the invention to Conrad Hubert, who decided to try selling the lights without the flower pot. Dubbed the Eveready Flashlight, it became a resounding success that made Hubert a multimillionaire. Cowen sold his first electric train in 1901 to a store owner in Manhattan, intending to use the train to call attention to other merchandise. The store.

Geniac - this direction if this light lights, etc.) The instruction book gave jumper positions and wiring diagrams for building a number of "computers." Current from a dry cell was routed through the rotary switches to light one or more flashlight bulbs. The kit allowed for the realization of fairly complicated Boolean equations, so the behavior of the "computer" could sometimes be interesting. A typical project was a "masculinity-feminity tester." The user was instructed to answer ten questions, such as "Which makes a better toy for a child: a) a doll, b) a toy truck." For each "a" answer, one wheel was turned one position clockwise; for each "b" answer, another wheel was turned one position clockwise; and the wiring diagram lit up a "more masculine" or "more feminine" bulb depending on which.
Emergency preparedness - infrastructure. For example, a subsidized "tourist" ferry can help a city on a river recover from an earthquake or flood-damaged bridges in a few hours, rather than weeks, by letting emergency traffic immediately restart. The first practical response is to discover funding. This is usually a political process. Next, recovery needs are prioritized. This prioritization may occur in the EOC, although for many recovery items, priorities will have to be set politically. The usual recovery is to repair essential bridges, roads, power, water and sewage systems. Some cities with crucial bridges "back them up" by subsidizing a "tourist" ferry, that can carry emergency traffic when a bridge goes down. Some advocates believe that government should change building codes to require autonomous buildings in order to reduce civil societies' dependence on complex,.
USS Utah (BB-31) - 1939 to participate in Fleet Problem XX, maneuvers observed personally by President of the United States Franklin D. Roosevelt from the heavy cruiser Houston. After providing mobile target services for the submarines of Submarine Squadron Six in the late autumn and early winter of 1939, Utah devoted the eight months that followed to special machine gun practices. The following summer, Utah sailed for the Hawaiian Islands reaching Pearl Harbor on 1 August 1940, and fired advanced antiaircraft gunnery practice in the Hawaiian operating area until 14 December 1940, when she sailed for the west coast, returning to Long Beach, Californiam, four days before Christmas. For the next two months, Utah operated as a mobile bombing target off San Clemente Island, California, for planes from Patrol Wing One, and from the carriers.
USS New Orleans (CA-32) - August to 7 December, 1936 and was once more in the Pacific early in 1937. Aside from winter training in the Caribbean early in 1939, she served out of California ports until joining the Hawaiian Detachment, 12 October 1939, for exercises, training, and, as war drew close, vigilant patrol. Moored in Pearl Harbor 7 December 1941, New Orleans was taking power and light from the dock, her engines under repair. With yard power out during the attack, New Orleans' engineers fought to raise steam, working by flashlight, while on deck men fired on the Japanese attackers with rifles and pistols. Though guns had to be worked by hand, within 10 minutes all her AA batteries were in action. A number of her crew were injured when a fragmentation bomb exploded close.
Dinghy - the dinghy with a security cable. The dinghy should be locked to its place when stored on deck in a harbour, or alongside a public dock. Propulsion Conventional dinghies are rowed. Usually there is one set of oarlocks for each thwart (seat). Sliding thwarts allow far more powerful rowing. A removable thwart can permit standing rowing. A sculling oar can substitute for several oars on a dinghy normally moved by other power. A nice refinement is to place a notch or oarlock in the transom (rear wall) for a sculling oar, with a tie-down so the scull need not be pushed down by hand. Outboard motors are also popular, though much more expensive. Engines always swing up so the dinghy can be grounded without damage. A horsepower per meter of length.
Deep sea fish - that live below the photic zone of the ocean. Examples include lanternfish, flashlight fish, cookie-cutter shark and anglerfish. Because these fish live in regions where there is no natural illumination, they cannot rely solely on their eyesight for locating prey, their mates etc. Instead they have had to develop alternative methods. Many deep sea fish are luminous, with extremely large dark-adapted eyes. Others have long feelers to help them locate prey in the eternal dark of the deep ocean..
A Hacker History - - become the venue of choice for phreaks and hackers to gossip, trade tips, and share secret phone numbers computer passwords and even credit card numbers. 1982 In Milwaukee a group of six teenagers hackers calling themselves the 414's (their area code) During a nine-day spree, the gang breaks into some 60 computers,systems at institutions ranging from the Los Alamos Laboratories to Manhattan's Memorial Sloan-Kettering Cancer Center. before being arrested 1983 Movie War Games shone a flashlight onto the hidden face of hacking 1983 Secret Service gets jurisdiction over credit card and computer fraud 1984, when a guy calling himself Lex Luthor founded the Legion of Doom. Named after a Saturday morning cartoon, the LOD had the reputation of attracting the best of the best — until one of the gang's.

Aron Ralston - out of water. Rather than die of exposure, he used a dull multitool he had with him to sever his arm. Although he refused to name which brand (other than to say it was not Leatherman), he did describe it as "the kind you get with a $15 flashlight and it's free, which is probably how I got it." On July 21, 2003, Ralston appeared on The Late Show with David Letterman..
Battery (electricity) - in a dilute sulfuric acid solution to make a secondary (rechargeable) battery. The original invention had a short shelf life, though. Around 1881, Emile Alphonse Faure, with his colleagues, developed batteries using a mixture of lead oxides for the positive plate electrolyte. These had faster reactions and higher efficiency. In 1878, the air cell battery was developed. In 1897, Nikola Tesla researched a lightweight carbide cell and a oxygen-hydrogen storage cell. In 1900, Thomas Edison developed the nickel storage battery. In 1905, Edison developed the nickel-iron battery. Like all electrochemical cells, Edison's produced a current of electrons that flowed only in one direction, known as direct current. In World War II, Samuel Ruben and Philip Rogers Mallory developed the mercury cell. In 1949, Lew Urry developed the small alkaline battery at.
The Body - take a look at it. Ray had gone out to pick berries and never got back. Apparently he got hit by a train. As usual, the gang spends their time hanging around in their treehouse playing cards and generally goofing off. Vern comes running, having overheard his older brother Billy speak about the corpse of Ray Bowers that they had found at a place called Back Harlow Road but didn't dare tell anyone about. The gang decides that they will go there to look at the corpse. Since it's longer than they can walk on one day, they tell their parents that they are going to camp in Vern's back yard, and then rig a flashlight in the tent to make it look as if they're there. Gordon's parents as usual.
Camping - natural areas of interest are popular venues for camping. Most campers prefer to use campsites with special facilities such as fire rings, bathrooms and utilities. (For more on facilities, see the campsite article.) Indeed, camping is often restricted by law to designated sites in order to prevent campers from damaging the environment, but not all campsite offer similar levels of development. Some campers may prepare food by cooking on a campfire, sometimes using such equipment as a Dutch oven. Common tent camping equipment includes: A tent, lean-to or other shelter device A sleeping bag for warmth A sleeping pad or air mattress is often placed underneath the sleeping bag for cushioning against sticks, small rocks, and other pointed objects A portable stove to prepare hot meals and/or drinks where campfires are.

Community emergency response team - teams for search-and-rescue, triage and first aid, planning, communication, logistics, and shelter. The city directly liaises with the neighborhood CERT leader through the CERT's organic communication team. In wealthy areas the communications may be by amateur radio, or dedicated telephone or fire-alarm networks. In poor areas, relays of bicycle-equipped runners can effectively carry mail between the districts and the city's emergency operations center. The CERT's block leaders and street teams provide truly local organization with in-depth local knowledge that can quickly locate shut-ins and injured persons and dangers, and liase between the neighborhood's people and professional emergency workers. They take the information back to the neighborhood leader, who assigns persons to the needs of the moment. In the short term, CERTs perform data gathering, especially to locate mass-casualties requiring professional response,.
Torch - soaked in pitch or some other flammable material wrapped around one end. In modern British English, a torch is an electrical flashlight. In construction usage, a torch is a hot flame, usually fueled by oxygen and acetylene, that is used to either cut or weld metals, particularly iron and steel. For example, blowtorch, cutting torch, or welding torch. Torch is also the stage name of Frederick Hahn, a German rapper and hip hop pioneer with Haitian roots. He is a member of Advanced Chemistry..
Tunnel rat - sent in to kill any buried enemy and to plant explosives to destroy the tunnels. A Tunnel Rat was equipped with only a semiautomatic M1911 handgun and a flashlight. The tunnels were very dangerous, with numerous booby traps and enemies lying in wait. Often there were flooded U-bends in the tunnels to trap gas. Guards manned holes on the sides of tunnels through which spears could be thrust impaling a crawling intruder. Tunnel Rats were generally men of smaller stature, and were often of Puerto Rican descent. The Tunnel Rats is also the name of a Punk Rock band from New Hampshire..
Scout Outdoor Essentials - be a lifesaver. A basic kit might include adhesive bandages, medical tape, sterile gauze, moleskin, soap, antiseptic, a mouth-barrier device for CPR, and scissors. Extra clothing to match the weather. Multiple layers are superior to a single massive jacket, because layered clothing is adaptable to a wide range of temperatures. Rain gear is very important. Being wet from rain may result in hypothermia, a potentially fatal condition. A flashlight is, of course, important for finding one's way at night. Trail food is good for maintaining your energy. However, the human body can reportedly survive for weeks without food, so starving to death should be the least of your worries if you become lost in the wilderness. Water is probably the most important of the Essentials. Dehydration may develop into heat exhaustion.
