Since the voltage that is induced in the coil is proportional to the rate of change ( derivative ) of current in the straight conductor, the output of the Rogowski coil is usually connected to an electrical ( or electronic ) integrator circuit to provide an output signal that is proportional to the current.

This property is used in telephony line repeaters and in circuits such as the Howland current source, Deboo integrator and load cancellers.

A bang-bang charge pump phase detector supplies current pulses with fixed total charge, either positive or negative, to the capacitor acting as an integrator.

A typical example are Howland current source and its derivative Deboo integrator.

A current integrator is an electronic device performing a time integration of an electric current, thus measuring a total electric charge.

Charge amplifier is an example of current integrator.

Another type ( called a Rogowski coil ) requires an external integrator in order to provide a voltage output that is proportional to the measured current.

implementation of an integrator and comes about because the current into the capacitor at the amplifier input is the current out of the capacitor at the amplifier output and the voltage is the integral of the current divided by the capacitance of C.

Q controls the electronic switch to generate the current impulse into the integrator.

For the remainder of that impulse the capacitor current ( c ) goes to zero and hence the integrator slope briefly goes to zero.

Following this impulse the full scale positive current is flowing ( c ) and the integrator sinks at its maximum rate and so crosses the threshold well before the next trigger edge.

The Government Accountability Office has since reviewed the Army's actions and issued a report that concluded that the Army and Boeing, the FCS lead systems integrator, followed the regulations to avoid conflicts of interest ; that although Raytheon's technology is not mature, the Army estimated that a prototype for current vehicles could be delivered by 2009 ; that Army officials found Trophy tests to be unrealistic, and worried that integrating Trophy would delay fielding other capabilities.

It is still used in making current population estimates in post-census years, though the value of these estimates is open to question.

While the U. S. Department of Labor has a program of projecting industry and occupational employment trends and publishing current outlook statements, there is little tangible evidence that these projections have been used extensively in local curriculum planning.

Moreover, the current information on what types of training are needed and possible is too limited and fragmentary.

This is not extended to anticipated levels of GNP, however -- only the current level of GNP affects the public pressure against wage-price increases.

electricity plays such an important part in community life today that it is difficult to envision a time when current was not available for daily use.

It is to be hoped that some way will be found to keep this important work current.

In general, P is a function of V and the current density, but it shall here be assumed as a constant.

The operator must continually supply the correct amount of turning current to the gyro torquers so that the effect of gyro drift is canceled.

If the Z gyro is drifting, a current generated by the autocollimator is delivered to the gyro torquer to cancel the drift.

The navy captain disclosed also that a list of questions found in Miss Gee's purse would, if completed and handed back, have given the Kremlin a complete picture `` of our current anti-submarine effort and would have shown what we are doing in research and development for the future ''.

There is also the traditional village politics of the Samoa Islands, the " faamatai " and the " faasamoa ", which continues in American Samoa and in independent Samoa, and which interacts across these current boundaries.

The role of fine art has been to simultaneously express values of the current culture while also offering criticism, balance, or alternatives to any such values that are proving no longer useful.

In chemical terms, proline is, therefore, an imino acid, since it lacks a primary amino group, although it is still classed as an amino acid in the current biochemical nomenclature, and may also be called an " N-alkylated alpha-amino acid ".

In the bow and stern technique, an anchor is set off each the bow and the stern, which can severely limit a vessel's swing range and also align it to steady wind, current or wave conditions.

Guthrie also saw traces of Acts in Polycarp's letter to the Philippians ( written between 110-140 ) and one letter by Ignatius († about 117 ) and thought that Acts probably was current in Antioch and Smyrna not later than c. 115, and perhaps in Rome as early as c. 96.

Thus, Abulafia in the 13th century assumed that the language spoken in Paradise had been different from Hebrew, and rejected the claim then current also among Christian authors, that a child left unexposed to linguistic stimulus would automatically begin to speak in Hebrew.
