Incus Berengario da Carpi in his "Commentaria super anatomia Mundini" (1521). Andreas Vesalius, in his "De humani corporis fabrica", was the first to compare the second element of the ossicles to an anvil, thereby giving it the name "incus". The final part of the long limb was once described as a "fourth ossicle" by Pieter Paaw in 1615. Incus The incus or anvil is a bone in the middle ear. The anvil-shaped small bone is one of three ossicles in the middle ear. The "incus" receives vibrations from the malleus, to which it is connected laterally, and transmits these to the
Analog ear Master". A number of U.S. (and foreign) patents on topics related to Stewart's analog ear were granted. In the order of filing dates starting in 1962, numbers are 3,294,909, 3,325,597, 3,387,093, 3,432,618, 3,378,700, 3,483,325, 3,459,034, 3,543,138, and 3,510,588. Several groups have built analog VLSI hearing chips in recent decades. Analog ear An analog ear or analog cochlea is a model of the ear or of the cochlea (in the inner ear) based on an electrical, electronic or mechanical analog. An analog ear is commonly described as an interconnection of electrical elements such as resistors, capacitors, and inductors; sometimes transformers and
