	Transient electromagnetic device - Wikipedia, the free encyclopedia
		A transient electromagnetic device (TED) is a device that emits a transient pulse of electromagnetic radiation of a few picoseconds in length.
		TEDs generally use spark gap switches, in oil or in pressurized gas pulse storage lines, or explosively pumped flux compression generators.
		TEDs have been examined by the US military for their threat potential as a weapon that harms computer systems.

	Electromagnetic pulse - Wikipedia, the free encyclopedia
		The electromagnetic radiation from an explosion (especially nuclear explosions) or an intensely fluctuating magnetic field caused by Compton-recoil electrons and photoelectrons from photons scattered in the materials of the electronic or explosive device or in a surrounding medium.
		The effects are usually not noticeable beyond the blast radius unless the device is nuclear or specifically designed to produce an electromagnetic shockwave.
		In the case of a nuclear detonation, the electromagnetic pulse consists of a continuous frequency spectrum.

	Father Ted -- Recommendations and Resources
		Ted, a ''bon vivant'', for something referred to only as "That Lourdes Thing," which apparently involved him misappropriating church funds which were intended to be used to send a poor child to Lourdes to go on a gambling trip to Las Vegas.
		Ted is not just wrong but appeals to the standard clichéd image of a Catholic Church-dominated Ireland, which is as phoney as a Britain full of people wearing bowler hats or a France peopled by men wearing striped jerseys with onions around their neck.
		Ted is a fairly normal priest, albeit with a significant financial impropriety in his past, who reflects in an unthinking manner the prejudices and hypocracies of his social and religious position.

	The Electromagnetic Bomb - a Weapon of Electrical Mass Destruction (Site not responding. Last check: 2007-08-19)
		Another aspect of electromagnetic bomb lethality is its detonation altitude, and by varying the detonation altitude, a tradeoff may be achieved between the size of the lethal footprint and the intensity of the electromagnetic field in that footprint.
		An electromagnetic bomb delivered by a conventional aircraft [7] can offer a much better ratio of electromagnetic device mass to total bomb mass, as most of the bomb mass can be dedicated to the electromagnetic device installation itself.
		A range of devices exist, however care must be taken in determining their parameters to ensure that they can deal with the rise time and strength of electrical transients produced by electromagnetic devices.

		The primary focus of this paper will be on a different and new form of HPM called Transient Electromagnetic Devices (TED) that could, in the hands of enemies, criminals, pranksters, or terrorists pose a significant threat to much of the United States infrastructure components that are based on micro-circuits and computer or micro-processor control.
		TEDs, on the other hand, are relatively simple devices that generally use simple spark-gap switches, either in oil or in pressurized gas pulse storage lines.
		Because of the simplicity of TED systems and the suspicion that they may cause disruptive effects to electronic systems that they are aimed at, they make an attractive approach for RF terrorists to use for various purposes.

	LEM Instruments, Inc. Digital Torque Sensing
		The reliability for transient torque measurements can no longer be guaranteed in all cases, because clear limits regarding their dynamic behavior are given and the motor rotor has inertia that influences the results of mechanical measuring methods.
		The device exclusively uses the acquisition of the instantaneous values of the stator currents and voltages and computes the electromagnetic torque, or dynamic air gap torque.
		The principle of the dynamic digital transient torque measurement is derived from the description of the electromagnetic behavior of an induction motor by means of space vectors.

		When transient wave signals are received by any type of antenna besides a TEM type, the output waveform will also be determined by the impulse characteristics of the receiving antenna and will result in a time-distortion of the received waveform.
		Transient wave signals make very good jamming waveforms since they occupy the entire bandwidth of the targeted receiver and their peak power is such that receiver circuit recovery (after initial receipt) further hampers receiver operation.
		Transient wave sources and weapons are a new technology that is not well known by many in the HPM community who have been working with narrow band systems for years.

	"The Design and Fabrication of a Damage Inflicting RF Weapon by 'Back
		This type of new weapon source, a transient electromagnetic device (TED), is actually a system that radiates an ESD-like signal that is intended to cause a similar responses, as just described, to the targeted system.
		A TED system provides both of these conditions, an RF electrostatic discharge nature and its output (the number of pulses per second) can be adjusted for maximum disruptive effect.
		It is highly likely that this type of device would be a very effective terrorist system and the findings of its design could be factored into another either a larger, higher powered device, or a more advanced design each with significantly greater effectiveness.

	CDRH Medical Device Electromagnetic Compatibility Program
		This is why some devices may be affected by a nearby transmitter of a certain frequency, and other devices at the same location may not be affected.
		The consequence of EMI with medical devices may be only a transient "blip" on a monitor, or it could be as serious as preventing an alarm from sounding or inappropriate device movement leading to patient injury or death.
		Because of the vast range of devices, and the time and resources it takes to develop mandatory standards, a more general approach is being planned to address EMC in all appropriate device areas with respect to the pre-market concerns.

	Untitled
		Commercial microelectronics make heavy use of metal oxide semiconductor devices which fail when subjected to voltages that exceed the dielectric strength of the component or when the device melts as a result of heating from currents induced by the RF pulse.
		This device is intended to be installed in front of sensitive antenna and receiver elements to protect them from damage or disruption by incident high power RF signals.
		The phrase non-nuclear electromagnetic pulse is sometimes used, because these weapons, which are indeed non-nuclear, project the same type of pulse we first learned of in conjunction with nuclear weapons.

	Cyber-Terrorist Weapons, Methods,and Techniques
		The TED has been referred to as the “weapon of choice to the modern cyber or infrastructure RF warrior.” A special category of RF weapon, the TED emits a large “spike” burst of energy (as opposed to a series of waves).
		TEMPEST devices capture data in the form of electromagnetic radiation emitted from electronic devices, and allow that data to be reconstructed.
		A TEMPEST device may capture the content displayed on your computer monitor screen, the contents of your computer’s memory, or the contents of mass storage devices.

		The TEDs do not even have a definable frequency but instead, because of their short time duration, they occupy a very large spectrum space, and you will find it everywhere on every radio dial.
		When a TED pulse is generated it will have the ability to excite responses in systems designed to receive at any frequency from as low as 100 MHz up to several GHz, from the FM band up to the lower microwave bands.
		A NB system would excite only those systems that were operating at its frequency, say 2.345 GHz, so a narrow band system must be "tuned" to a given target's known soft spot but a TED system would go after any soft spot of the target platform, back-door or front door [3].

	Directed Energy and Fleet Defense:
		The framework for this study is an integrated system of microwave devices, high-energy lasers, and surface-to-air missiles which are evaluated in terms of their ability to enhance anti-ship cruise missile defense, tactical air defense, and fast patrol boat defense.
		With their origin in the radio and radar devices developed in the first half of the twentieth century, microwave devices pre-dated the development of lasers.
		While each of these devices has advantages and limitations, the significant progress made in the last ten years strongly suggests that high power RF weapons can be produced within the next two decades.

		Every electronic, electro-optical or electromechanical device gives off some type of electromagnetic signals, whether or not the device was designed to be a transmitter.
		Since World War II, scientists have known that the EMR that "leaks" from devices can be intercepted and, using the proper equipment, reconstructed on a different device.
		The distance at which emanations can be monitored depends on whether or not there are conductive media such as power lines, water pipes or even metal cabinets in the area that will carry the signals further away from the original source.
