/ˈɪntɪɡreɪtə/

Etymology: < Latin integrātor, noun of action from integrāre to integrate v. (In Latin only in sense ‘renewer’.)

One who or that which integrates; spec. an instrument for indicating or registering the total amount or mean value of some physical quantity, as area, temperature, etc.: see integrate v. 3b.

integrator1876

1876 W. Thomson in Proc. Royal Soc. 24 269 I have made many attempts to plan a mechanical integrator which should give solutions by successive approximations... We have the instrument founded on my brother's disk-, globe-, and cylinder-integrator.

1879 W. Thomson & P. G. Tait Treat. Nat. Philos. (new ed.) I: Pt. i. 497 I have made many attempts to plan a mechanical integrator which should give solutions by successive approximations.

1884 S. P. Thompson Dynamo-electr. Machinery iv. 59 Fig. 48 gives the curve as integrated..for me from Fig. 47 by the aid of the very ingenious curve integrator of Mr. C. Vernon Boys.

1898 Daily News 24 Jan. 5/6 The photographs, including those taken with the integrator, are very good.

1931 Jrnl. Franklin Inst. 212 450 There has been an enormous change in technique since the time when Sir William Thomson first suggested..that the integrators developed by his brother could be connected together and thus forced to produce solutions of differential equations.

1938 Math. Gaz. 22 343 Integrators... Any continuously variable gear can act as an integrating mechanism.

1955 T. L. Martin Electronic Circuits 618 Waveform relationships in integrators and differentiators.

1964 Ann. N.Y. Acad. Sci. 115 571 Until recently, analog computers have depended on the use of relays for mode control, switching, and resetting of integrators.
