Did You Know...
...that the video game, Pong, was invented by a guy who graduated at the bottom of his engineering class? Nolan Bushnell spent more time running the games at a local amusement park than he did on his studies at the University of Utah. His dreams of working for Disney's amusement empire were dashed when the company wouldn't hire him. Taking a boring job, Nolan daydreamed about electronic versions of popular games. He invented Pong, the first video game, and went on to found Atari Co.

| Number | Title | Issue Date |
| 6011448 | Method and apparatus for frequency modulation synthesis A method for frequency modulation synthesis and apparatus for performing the method. The method uses additions rather than multiplies and therefore saves the space and cost of multipliers in circuit implementations. The method saves further resources by u... | 01/04/2000 |
| 5756919 | Musical sound generating system including pseudo-sinusoidal wave operator A musical sound generating system not requiring a memory unit or interpolation device for generating a tone having a tone color including a large number of harmonic components. The tone is generated with few operations and ready predictability of tone col... | 05/26/1998 |
| 5464947 | Apparatus for and method of producing fluctuations in sound for electronic sound system According to the invention, a plurality of pieces of frequency modulation information are weighted independently and then synthesized. The individual pieces of synthesized frequency modulation information are weighted independently, and individual pieces ... | 11/07/1995 |
| 5194684 | Method and apparatus for selective reduction of upper harmonic content in digital synthesizer excitation signals Variable frequency sawtooth waveforms are often utilized as an excitation signal in a digital musical synthesizer. A problem exists at lower sampling rates in such systems due to an aliasing problem which occurs at frequencies near the Nyquist rate. Low p... | 03/16/1993 |
| 5182415 | Musical tone synthesizing device A musical tone synthesizing device employing an operator, for generating musical tone signals by a modulation operation process.
