Some species use vibrations for communicating within members of the same species, such as to attract mates as in the songs of the shield bug Nezara viridula. Vibrations can also be used to communicate between entirely different species; lycaenid (gossamer-winged butterfly) caterpillars which are myrmecophilous (living in a mutualistic association with ants) communicate with ants in this way. The Madagascar hissing cockroach has the ability to press air through its spiracles to make a hissing noise as a sign of aggression; the Death's-head Hawkmoth makes a squeaking noise by forcing air out of their pharynx when agitated, which may also reduce aggressive worker honey bee behavior when the two are in close proximity.
What is a lycaenid caterpillar? 
gossamer-winged butterfly

The first practical ICs were invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor. Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". Noyce also came up with his own idea of an integrated circuit half a year later than Kilby. His chip solved many practical problems that Kilby's had not. Produced at Fairchild Semiconductor, it was made of silicon, whereas Kilby's chip was made of germanium.
When was the first functional IC demonstrated?
12 September 1958.

Atari Games created a line of NES products under the name Tengen and took a different approach. The company attempted to reverse engineer the lockout chip to develop its own "Rabbit" chip. However, Tengen also obtained a description of the lockout chip from the United States Patent and Trademark Office by falsely claiming that it was required to defend against present infringement claims in a legal case. Nintendo sued Tengen for copyright infringement, which Tengen lost as it could not prove that the legally obtained patent documents had not been used by the reverse engineering team. Tengen's antitrust claims against Nintendo were never finally decided.
Tengen got a description of Nintendo's chip from whom?
United States Patent and Trademark Office
