	Automatic Warning System
		The Automatic Warning System (AWS) is provided as a safeguard against a driver failing to respond to a signal or misreading its aspect.
		The system did not lend itself to use on single track railways, as complex arrangements were necessary to avoid unwanted indications being given to trains running in the opposite direction to which the ramp applied.
		The ATC system was redesignated "Western Region Automatic Warning System" (WR AWS) by British Railways, in 1959.

	Automatic Warning System - Wikipedia, the free encyclopedia
		The system is fail-safe because the electromagnet is required to be energised to give the 'safe' indication, the 'danger' indication being given by the permanent magnet alone.
		When the warning is acknowledged, the horn stops and the visual indicator changes to a pattern of fl and yellow spokes, which persists until the next AWS inductor, thus reminding the driver visually that he has passed a restrictive signal aspect.
		The system suffers one drawback in that on single track lines, the track equipment will set the AWS system on a train travelling in the opposite direction from that for which the track equipment is intended, but not reset it as the electromagnet is encountered before the permanent magnet.

	The Automatic Warning System
		When a distant signal is at 'caution', the permanent magnet situated between the running rails alters the receiver setting on the vehicle, causing the AWS horn to sound and the initiation of a full brake application after a short delay.
		If the distant signal is at 'clear' the electro magnet is energised, which restores the receiver setting to its normal position, the action of which causes a bell to ring in the driving compartment for three seconds.
		In this system two magnets are fixed centrally between the rails, 2ft 6in apart, generally 200 yards on the approach side of the signal.

	Crosswalk Warning System Evaluation (Site not responding. Last check: 2007-10-26)
		The In-Pavement Flashing Lights Crosswalk Warning System’s purpose was to warn the driving public of the presence of pedestrians in the crosswalk at uncontrolled intersections.
		The warning system is expected to be extremely effective over the long term in enhancing driver awareness of the presence of a pedestrian during the hours of darkness.
		Agencies that install the system should ensure that the public is educated on the proper use of the device by both drivers and the pedestrian.

	BBC News \| UK \| How the safety systems work
		The government is committed to expanding this type of warning system across the network by the end of 2003.
		The two systems at the centre of the controversy are Automatic Train Protection (ATP) and the less sophisticated Train Protection Warning System (TPWS).
		The situation in the case of the Paddington crash is not entirely clear, but it is thought that a faulty track could have triggered the wrong noise in the cabin of the driver of the Thames train leading him to believe he had been given a green signal instead of a red one.

	Emergency Alert Systems \| Emergency Notification \| Emergency Broadcast Services with Emergency Response & Disaster ...
		The Red Cross uses this system for internal phone notification to alert its key employees and emergency response personnel during a disaster.
		Our phone system automatically dials a phone number and plays a recorded message when it detects a person answers the call or when an answering machine message is detected.
		Unlike some systems that are limited by the number of lines available to perform this emergency dialing, our service is provided to you using a network of phone dialers that can deliver your emergency messages much faster.

	PUBLIC ROADS On-Line (Spring 1994): An Automatic Warning System to Prevent Truck Rollover on Curved Ramps
		The system warns drivers when the truck, based on its load conditions and speed, would roll over if its speed were not reduced.
		Ideally, an automatic truck warning system would detect a truck's weight and center of gravity sufficiently in advance of a curved ramp, "know" the curvature and superelevation of the ramp, and warn the truck driver to reduce speed to a level below the vehicle's rollover threshold speed.
		The benefits from this automatic warning system are a reduction in truck rollover accidents and in the associated costs.

	REGIONAL EARLY TSUNAMI WARNING SYSTEMS UTILIZING SYSTEM TECHNOLOGY - by Dr. George Pararas-Carayannis
		Such hardware system can be tailored to the needs of national disaster control authorities and skillfully adopted to their existing response apparatus, to enhance the capability to cope with their tsunami threat.
		The basic concept was to develop the technology for regional early warning systems for areas exposed to tsunamis generated by local earthquakes, and for areas for which PTWC could not provide suitable information within one hour after tsunami, generation.
		In designing a complete regional system, warning dissemination has to be based on complete and thorough examination of the host country's tsunami response infrastructure to determine lines of responsibility, how the system works, where it could be improved, what its basic requirements are, and how best to integrate the early warning technology into it.

	Earthquake Early Warning System
		n earthquake warning system has been developed to provide a time series profile from which vital parameters such as the time until strong shaking begins, the intensity of the shaking, and the duration of the shaking, can be derived.
		The warning system is designed to analyze the first-arrival from the three components of an earthquake signal and instantaneously provide a profile of impending ground motion, in as little as 0.3 sec after first ground motion is felt at the sensors.
		Many site-specific warning systems that are in use today wait for ground motion measurements to exceed a preset threshold.

	[No title]
		The GWR was a pioneer in cab signalling, devising and applying an effective system by 1906 that survived, with slight modifications, into the 1980's, when it was finally superseded on ex-GWR lines by the British Railways intermittent inductive AWS that is still in use.
		The system used was the patent Miller system, which employed a ramp and shoe almost identical to the GWR ATC, except that the ramp was outside the rails on the right-hand side, and the shoe was mounted on a tender bogie journal.
		On the locomotive, the automatic brake valve was mechanically rotated to service application position by a chain and pneumatic piston unless the driver acknowledged a restrictive signal.

	Swiss say radar was out of date - theage.com.au
		Earlier in the day, Swiss air controllers said an automatic warning system was shut down for maintenance when the two planes - a Russian passenger jet bound for Spain and a Boeing cargo plane headed for Belgium - slammed into each other Monday night, killing all aboard.
		Skyguide said it was asking why the air traffic controller on duty did not intervene earlier to warn the pilot of the Russian airliner of the accident risk, and why the pilot only began a dive manoeuvre after a second warning.
		The news that the Swiss radar system was out-of-date and imprecise, reported earlier by Swiss German television, was confirmed by BEAA head Jean Overney in the capital Bern.

	Guardian \| Warning system was off
		Switzerland's air traffic control company yesterday admitted its automatic collision warning system was turned off for maintenance on Monday when a Boeing 757 and a Russian Tupolev 154 slammed into one another and exploded in a fireball above Lake Constance.
		The sole air traffic controller on duty at the time of the accident, who told the Russian pilot to dive a mere 50 seconds before the impact, was reportedly too traumatised to talk to investigators yesterday.
		In Zurich, Roger Gaberelle, a Skyguide official, confirmed that "the [automatic collision warning] system was not working at the time".

	New Earthquake Warning System (Site not responding. Last check: 2007-10-26)
		Level C warnings would automatically appear on scrolls on local television and be broadcast to local radio stations, radio alert systems, and personal earthquake warning beeper systems.
		The public is not bothered by the Warning System unless they live in area that has a large number of quakes, and then only if the Level C risk level is reached.
		The system is automatic, in the sense that warnings are based not upon hunches or educated guesses by people, but by local, regional, real-time, scientific risk factors.

	Principles of Operation
		Anytime the system is turned on, whether activated at engine start up (wired through the ignition) or by the power switch on the front of the control panel, it will automatically be set at its most sensitive setting.
		At this setting, the system can sense as little as 110 volts AC, warning the operator (and crew) that he is in the vicinity of a high-voltage power line.
		SIGALARM continues to warn until the boom is withdrawn from the danger zone.

	Bioterror fears prod warning systems
		A few existing warning and surveillance networks are being built, but none yet has the nationwide reach needed to serve as an official national emergency channel, similar to the U.S. Civil Defense radio broadcast channel used in the 1950s and 1960s.
		The system, which is not yet functioning, is supposed to track emerging outbreaks by allowing analysts to search and map disease reports and lab results provided by state and local health departments.
		Another system, overseen by the Air Force, is already in place in some two dozen military and civilian hospitals.

	Warning, Evacuation, and In-Place Protection Handbook
		The method of disseminating the warning needs to take into account the time of day, day of the week, and the season as these provide indications where people will be located and whether their activities can be penetrated by a warning.
		This system was developed to be used when conditions warrant issuance of public information in a given location, but when the situation is not severe enough to activate the EBS system.
		System is not understood by most law enforcement agencies and is rarely used as a warning method.

	Guardian \| Trains 'ran without warning system'
		The file reveals that the company allowed its 125mph trains to run with a faulty automatic warning system (AWS) on 63 services in the eight months before the crash in September 1997.
		When the system is working correctly it alerts train drivers with a loud klaxon blast if they fail to brake at red warning lights and will stop the train unless it is overridden by the driver.
		Last month the deputy prime minister John Prescott announced the introduction of a £150m train protection warning system to be in place by the end of 2003.
