Elizabeth Way was the first operator ; ;

and a night operator was also employed.

In 1931 Mrs. F. H. Briggs, agent and chief operator, who was to retire in 1946 with thirty years' service, led agency offices in sales for the year with $2,490.

Another veteran telephone operator was Edith Fleming Blackmer, who had been in the office forty years at the time of her death in 1960.

He also paid close attention to his work quickly learning to distinguish the differing sounds the incoming telegraph signals produced and learned to translate signals by ear, without having to write them down and within a year was promoted as an operator.

Once the operator took his finger off, the player would speed up until its tachometer was back in phase with the master, and as this happened, the phasing effect would appear to slide up the frequency spectrum.

The syntax for expressions let the multiplication operator be omitted, e. g. was treated as, and was treated as if was not an array.

* Moviline ( Telefónica Servicios Uno since 1971, Moviline since 1994 ) was the analogue service provider for the Spanish operator.

It was poor operational procedures and sloppy operator behaviour that allowed the GC & CS cryptanalysts to find ways to read them.

British Railways ( BR ), which from 1965 traded as British Rail, was the operator of most of the rail transport in Great Britain between 1948 and 1997.

If that steady-state signal was interrupted, it indicated one of two things: either the operator was about to start transmitting, or something else had happened to break the connection — such as a physical break in the telegraph line.

Corus itself was taken over in March 2007 by the Indian steel operator Tata Steel.

Once the keys had been pressed they were locked down until mechanical contacts in a distributor unit passed over the sector connected to that particular keyboard, when the keyboard was unlocked ready for the next character to be entered, with an audible click ( known as the " cadence signal ") to warn the operator.

The earliest known chord keyboard was part of the " five-needle " telegraph operator station, designed by Wheatstone and Cooke in 1836, in which any two of the five needles could point left or right to indicate letters on a grid.

In 1874, the five-bit Baudot telegraph code and a matching 5-key chord keyboard was designed to be used with the operator forming the codes manually.

As there were no users waiting at an interactive terminal, this was no problem: users handed in a deck of punched cards to an operator, and came back a few hours later for printed results.

When the bridge was in use, boaters would signal the operator, who would start a diesel engine and rotate the bridge to the open position on a large gear.

Loop disconnect range was restricted by telegraphic distortion and other technical problems, and placing calls over longer distances required either operator assistance ( operators used an earlier kind of multi-frequency dial ) or the provision of subscriber trunk dialing equipment.

Based on this prior success with using MF by specialists to establish long-distance telephone calls, Dual-tone multi-frequency ( DTMF ) signaling was developed for the consumer to signal their own telephone-call's destination telephone number instead of talking to a telephone operator.

His only formal education was at his local primary school, after which he carried out agricultural work on his father's farm before joining the French Post & Telegraph Administration as an apprentice operator in 1869.

Once the keys had been pressed they were locked down until the contacts again passed over the sector connected to that particular keyboard, when the keyboard was unlocked ready for the next character to be entered, with an audible click ( known as the " cadence signal ") to warn the operator.

During the summers, Towsley often needed the assistance of a company operator.

Store employees are also needed to authorize " age-restricted " purchases, such as alcohol, solvents or knives, which can either be done remotely by the employee observing the self-checkout, or by means of a " store login " which the operator has to enter.

It is needed to make the right hand side operator elliptic.

Eventually, the " rapid " firing mechanism was perfected and miniaturized to the extent that either the recoil of the firearm or the gas pressure from firing could be used to operate it, thus the operator needed only to pull a trigger ( which made the firing mechanisms truly " automatic ").

In addition, the same operator can move the train as needed.

It also cut costs by allowing Nixie tubes, seven-segment displays, and calculators to be used for the operator consoles, where binary displays were too complex to use, decimal displays needed complex hardware to convert radices, and hexadecimal displays needed to display more numerals.

It flashes to alert the operator that change is needed, hand pay is requested or a potential problem with the machine.

Callers previously needed operator assistance even to make domestic long-distance calls.

In a two factor transaction, the presented credential and a second factor are needed for access to be granted ; another factor can be a PIN, a second credential, operator intervention, or a biometric input.

Automated monitoring was needed not just for CPU usage but for counting pages printed, cards punched, cards read, disk storage used and for signaling when operator intervention was required by jobs such as changing magnetic tapes and paper forms.

Programs needed to be loaded by an operator ; the processor could not boot itself.

In either case the engagement is entirely automatic, with no operator guidance needed.

However, the civilian airport operator needed the upgrades.

If a different size or style was needed, the operator would switch to a different magazine.

When a space is needed, the operator touches the spaceband lever just to the left of the keyboard.

From the sorts stacker, the machine operator can ( manually ) pick pi matrices and insert them into the line being assembled as needed.

Whenever anyone needed to make a call ( via Miss Paulifficate the Castle operator ), he or she would stand under the cage, look up and signal for the cage to come down.

In fractional calculus, however, since the operator has been fractionalized and is thus continuous, an entire complementary function is needed, not just a constant or set of constants.

The line is wrapped around the spool and can be tightened and reeled in by pulling the tail line, the winch takes the load once the pull is stopped with little operator tension needed to hold it.

As with other missions, the EOD operator provides the area commander with an assessment of the situation and of support needed to complete the mission.

A relevant operator is needed to describe the macroscopic behaviour of

The operator also needed to hold down the " subtraction cutoff tab " corresponding to the leftmost digit of the answer.

As a consequence of its definition, the Sobel operator can be implemented by simple means in both hardware and software: only eight image points around a point are needed to compute the corresponding result and only integer arithmetic is needed to compute the gradient vector approximation.
