During the 1980s, further scientific evidence to confirm the existence of lucid dreaming was produced as lucid dreamers were able to demonstrate to researchers that they were consciously aware of being in a dream state ( again, primarily using eye movement signals ).

Radial movement is usually linked with Doppler frequency to produce a lock signal that cannot be produced by radar jamming signals.

The types of signals produced by a SEM include secondary electrons, back-scattered electrons ( BSE ), characteristic X-rays, light ( cathodoluminescence ), specimen current and transmitted electrons.

Integrins are produced by a wide variety of cells ; they play a role in cell attachment to other cells and the extracellular matrix and in the transduction of signals from extracellular matrix components such as fibronectin and collagen.

Other signals produced by the mixer ( such as due to stations at nearby frequencies ) can be very well filtered out in the IF stage, giving the superheterodyne receiver its superior performance.

This produced a better bias than by mixing the two signals in the recording head, but mechanical tolerances for cross-field are tight.

Each signal produced by the ECL circuitry was a differential pair, so the signals were balanced.

* If the high and low signal levels have the same voltage with opposite polarity, coded signals have zero average DC voltage, thus reducing the necessary transmitting power and minimizing the amount of electromagnetic noise produced by the transmission line.

Fessenden's detector was not needed to receive the damped wave signals produced by the spark gap transmitters that were common at the time.

Antenna gain is usually defined as the ratio of the power produced by the antenna from a far-field source on the antenna's beam axis to the power produced by a hypothetical lossless isotropic antenna, which is equally sensitive to signals from all directions.

Some signals are produced from the actual cell surface in this case but other signals seem to emanate from within the endosomes.

The speculation is that some substance is produced in that portion of the small intestine that signals body cells to become insulin resistant.

Theoretically, there are 2 < sup > 2 < sup > m </ sup ></ sup > possible Boolean functions of these m signals, but the structure of the ROM allows just of these functions to be produced at the output pins.

This effectively eliminates false signals produced by trees, clouds, insects, birds, wind, and other environmental influences.

In 1947, affidavits were filed with the Commission by various clear-channel stations alleging that extensive interference was being caused to the service areas of these stations during daylight hours, from class 2, stations whose signals were being reflected from the ionosphere so as to create skywave intereference.

Occasionally they heard gun-shot signals and a number of horsemen were sighted on the hills, disappearing at the posse's approach.

The batteries on the bugging device I had put on the car were still fresh enough to send out good strong signals.

All broadcast television systems preceding digital transmission of digital television ( DTV ) were systems utilizing analog signals.

The comparison of these two signals enabled logic circuits to determine the true target reflection signal, even if the target were to eject radar-reflecting chaff.

As signals, beacons are an ancient form of optical telegraphy, and were part of a relay league.

Both of the two German electro-mechanical rotor machines whose signals were decrypted at Bletchley Park, Enigma and the Lorenz Cipher ', were virtually unbreakable if properly used.

Previous schemes for color television systems, which were incompatible with existing monochrome receivers, transmitted RGB signals in various ways.

During pre-Columbian warfare, Aztec nations were known to have used drums to send signals to the battling warriors.

Appointments by influence were common in the navy at this time, but the significance of Beatty's choice lay in Seymour's relative inexperience as a signals officer, which later resulted in difficulties in battle.

* Failing to ensure that signals sent to his ships were handled properly and received by the intended ships.

The accuracy was limited by the accuracy of optical observation, and corrections of clocks and time signals were published in arrear.

103, 898 " Système de télégraphie rapide "), in which the signals were translated automatically into typographic characters.

Five contacts were used to send a group of signals making up a single character for transmission.

Correcting signals were transmitted to keep both ends in synchronisation.

The signals from the telegraph line were temporarily stored on a set of five electromagnets, before being decoded to print the corresponding character on paper tape.

Within a few years a majority of households were FM equipped, by the 1980s a majority of cars sold had FM stereo radios and a majority of listening in the U. S. was devoted to FM signals according to the Arbitron rating service.

A century before that, during the 15th century, the three colours were mentioned as the coastal signals for this area, with the 3 bands straight or diagonal, single or doubled.

Hourly time signals from Greenwich Observatory were first broadcast on 5 February 1924, rendering the time ball at the observatory obsolete in the process.

On 24 September 1900 radio telegraphy signals were exchanged regularly with the island of Heligoland over a distance of 62 km.

Other specialist staff were navigation, signals and intelligence personnel.

The DTMF system uses eight different frequency signals transmitted in pairs to represent 16 different numbers, symbols and letters-as detailed below.

AAUI signals have the same description, function, and electrical requirements as the Attachment Unit Interface ( AUI ) signals of the same name, as detailed in IEEE 802. 3-1990 CSMA / CD Standard, section 7, with the exception that most hosts provide only 5 volt power rather than the 12 volts required for most AUI transceivers.

" In Saigon, Ambassador Graham Martin refused to believe the SIGINT ( signals intelligence ) reporting that detailed the massive North Vietnamese military buildup taking place all around ( Saigon ) ... and repeatedly refused to allow NSA's station chief, Tom Glenn, to evacuate his forty-three man staff and their twenty-two dependents from Saigon.

that provide detailed information on aids to navigation with their locations and characteristic signals is currently maintained by the U. S. Coast Guard in its Light List issued each year.

As in the case of electrical signals, bandwidth is a measure of how finely detailed an image is ; the finer the detail, the greater the bandwidth required to represent it.

W-CDMA has been developed into a complete set of specifications, a detailed protocol that defines how a mobile phone communicates with the tower, how signals are modulated, how datagrams are structured, and system interfaces are specified allowing free competition on technology elements.

On May 17, 2006, NavySEALs. com and MediaChannel. org published an exclusive interview with Miller in which she detailed how the attack on the Cole spurred her reporting on Al Qaeda and led her, in July 2001, to a still-anonymous top-level White House source, who shared top-secret NSA signals intelligence ( SIGINT ) concerning an even bigger impending Al Qaeda attack, perhaps to be visited on the continental United States.

By bouncing radar signals off the asteroid, a team of astronomers at the Arecibo radio telescope in Puerto Rico were able to develop a more detailed computer model of its shape, which confirmed the earlier results.

The path creates a virtual access capability that circumvents the normal inputs and outputs, providing direct control of the device and detailed visibility for signals.
