Signals intelligence work can be dangerous even in peacetime.

Signals of interest can include sound, images, and sensor data, for example biological data such as electrocardiograms, control system signals, telecommunication transmission signals, and many others.

Signals can be quite sophisticated: with vehicle sensors embedded in the pavement, the signal can control and choreograph the turning movements of heavy traffic in the most complex of intersections.

Signals such as opening their mouth in preparation for food, rejecting unwanted foods, and spending an increased amount of time watching their helpers, indicates that guided feeding therapy can increase engagement in eating in some cases.

Signals travelling along different paths can have different Doppler shifts, corresponding to different rates of change in phase.

Signals can be continuous or discrete in time, as well as continuous or discrete in the values they take at any given time:

Signals can be recorded from cerebral cortex, brain stem, spinal cord and peripheral nerves.

Signals that consistently precede food intake can become conditioned stimuli for a set of bodily responses that prepares the body for food and digestion.

Signals can be, but aren ’ t limited to, H. 323 and Session Initiation Protocol ( SIP ) Protocols.

Signals can be categorized in various ways.

Signals in nature can be converted to electronic signals by various sensors.

Signals have been kept only in areas where points are present, but only use a white light, meaning that the route has been assigned and the driver can use cab signalling.

Signals in the ELF frequency range, however, can penetrate much deeper.

Signals can be either subdural or epidural, but are not taken from within the brain parenchyma itself.

Signals are integrated over time and thus the RADAR " beam " is synthetically reduced to a much smaller aperture – or more accurately ( and based on the ability to distinguish smaller Doppler shifts ) the system can have hundreds of very " tight " beams concurrently.

Signals sent by radio ( or over long wires or when stored on magnetic media ) must be modulated with some method that prevents their signal from degrading before the signals can be received.

Signals that are below the noise floor can be detected by using different techniques of spread spectrum communications, where signal of a particular information bandwidth is deliberately spread in the frequency domain resulting in a signal with a wider occupied bandwidth.

Signals can be launched at the transmitter end of a XAUI line without precisely matching the routing of the four lanes, and the signals will be automatically de-skewed at the receiver.

Signals are often generated through a contrarian mean-reversion principle but can also be designed using such factors as lead / lag effects, corporate activity, short-term momentum, etc.

Signals which are registered only at one or few geophones can be attributed to unwanted, local events and thus discarded.

Signals are broadcast across the program, and that means any process can read or write a signal.

Signals which the dispatcher can control are represented as either at Stop ( typically red ) or " displayed " ( typically green ).

Signals from the stations can also be received in parts of Iowa, South Dakota and North Dakota.

Signals traveling along that beam will be reinforced.

Signals offset from that beam will be canceled.

In 2008, the drug was put on the FDA's Potential Signals of Serious Risks List to be further evaluated for approval.

Signals could be sent either direction: Gondor could signal Rohan, and Rohan could signal Gondor.

Signals of different types should be grouped in different citation sentences.

Signals are easily stored and transmitted in digital form, but a DAC is needed for the signal to be recognized by human senses or other non-digital systems.

Signals will be modified to provide proper movements.

Signals are to be considered and counted only if A, B, and C detect them trial-by-trial together ; i. e. for any one signal which has been detected by A in one particular trial, B must have detected precisely one signal in the same trial, and C must have detected precisely one signal in the same trial ; and vice versa.

Signals could only travel one direction along the line, so head-end stations must be present on the line to repeat the signals ( ensuring that no packets travel through the line indefinitely ) on either another, backwards direction frequency on the same line, or another line entirely.

Signals that unauthorized lights are to be extinguished.

War All the Time spawned two singles, " Signals Over the Air " and " War All the Time ", though the latter received considerably less attention due to MTV banning the video for controversial material involving a fake news feed that appeared to be real and teenagers being weapon targets.

Signals may also be sent by handkerchief, such as the American LGBT handkerchief codes.

There was to be a reduction of 46 regiments of the Royal Artillery, 18 battalions of infantry, 12 regiments of the Royal Engineers and 2 regiments of the Royal Corps of Signals.

Before the Second World War, Royal Signals recruits were required to be at least 5 feet 2 inches tall.

* 2nd Signal Brigade: ( To be disbanded in late 2012 ) The Brigade Headquarters is located at Corsham and comprises 10, 32, 37, 38, 39 and 71 Signal Regiments, plus 299 Signal Squadron ( Special Communications ), Specialist Group Royal Signals with 81 Signal Squadron, Land Information and Communications Services Group ( LICSG ), Land Information Assurance Group ( LIAG ) and the Central Volunteer Headquarters ( CVHQ ) Royal Signals.

The COLREGs are contained within the Merchant Shipping ( Distress Signals and Prevention of Collisions ) Regulations of 1996 as amended from time to time and is distributed and accessed in the form of a " Merchant Shipping Notice " ( MSN ), which is used to " convey mandatory information that must be complied with under UK legislation.

A corps ( " core "; the plural is spelled the same as singular but pronounced " cores "; from French, from the Latin corpus " body ") is either a large formation, or an administrative grouping of troops within an armed force with a common function such as Artillery or Signals representing an arm of service.

Signals to operate control surfaces on the tail were sent via two wires, which unwound from bobbins housed within long, bullet-shaped fairings, themselves mounted either on the roots of an opposing pair of the larger mid-body fins, or on those same fins ' opposing tips.

The stop instruction is specified with either an English or local language legend in the United Nations Convention on Road Signs and Signals.

Signals are either heavily attenuated by the building materials or reflected as in multipath.
