Context_1 : In computing, a hardware random number generator (true random number generator, TRNG) is a device that generates random numbers from a physical process, rather than a computer program. Such devices are often based on microscopic phenomena that generate low-level, statistically random "noise" signals, such as thermal noise, the photoelectric effect, involving a beam splitter, and other quantum phenomena. These stochastic processes are, in theory, completely unpredictable, and the theory's assertions of unpredictability are subject to experimental test. A hardware random number generator typically consists of a transducer to convert some aspect of the physical phenomena to an electrical signal, an amplifier and other electronic circuitry to increase the amplitude of the random fluctuations to a measurable level, and some type of analog to digital converter to convert the output into a digital number, often a simple binary digit 0 or 1. By repeatedly sampling the randomly varying signal, a series of random numbers is attained. Context_2 : Bernard A Yurash (February 17, 1921 – January 25, 2007) was a significant contributor to the creation of the first commercially viable CMOS integrated circuits by finding the sources of mobile sodium ions coming from the manufacturing process. Today, virtually all digital electronics use CMOS circuitry. Bernard worked at Fairchild Semiconductor in Silicon Valley from 1958 ( he was employee number 158 ), through the buyouts of the company by Schlumberger and National Semiconductor, and finally retiring in 1990. In the 1960s Fairchild Semiconductor, a division of Fairchild Camera and Instrument Corp., and Texas Instruments, revolutionized electronics by employing the first integrated circuit technology. Fairchild's Robert Noyce filed for this patent using deposited (printed) metal lines and Jean Hoerni's Planar Process ( patent also filed by Jack Kilby of Texas Instruments but with using bonding wires ). At the time virtually all the devices were of the bipolar type which were used to construct RTL and DTL type circuits ( Resistor-Transistor-Logic, Diode-Transistor-Logic), which unfortunately drew more power than was desired, and eventually lost ground to Texas Instruments' TTL (Transistor-Transistor-logic). The next great technological leap in computer chips would be CMOS transistors, which promised significantly lower power and greater circuit density than the Bipolar circuitry. Although Frank Wanlass first filed for the CMOS patent in 1963, Fairchild could not produce the devices for commercial output for many years because of the mystery of the mobile ions degrading their performance. Much research time and money was expended in 1967 and 1968 at Fairchild on trying to manufacture the highly promising technology, the MOS SGT ( Metal Oxide Semiconductor Silicon Gate Technology ) circuits utilizing the field effect from the "gate" on the conducting "channel" from source to drain. Context_3 : Ruth White (born 1925) is an American composer known for her electronic music compositions. While most of her career was dedicated to educational recordings, she is best known for being an electronic music pioneer, owing to her early explorations of sound using the Moog synthesizer. The back cover of her 1971 release "Short Circuits" stated that “Ruth White is considered among today’s most gifted arbiters of what is termed ‘the new music’". Context_4 : An electronic musical instrument is a musical instrument that produces sound using electronic circuitry and/or digital devices. Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and/or listener. Context_5 : This is a list of electronic music genres, consisting of genres of electronic music, primarily created with electronic musical instruments or electronic music technology. A distinction has been made between sound produced using electromechanical means and that produced using electronic technology. Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, and the electric guitar. Purely electronic sound production can be achieved using devices such as the Theremin, sound synthesizer, and computer. Genre however is not always dependent on instrumentation. Context_6 : Multielectrode arrays (MEAs) or microelectrode arrays are devices that contain multiple plates or shanks through which neural signals are obtained or delivered, essentially serving as neural interfaces that connect neurons to electronic circuitry. There are two general classes of MEAs: implantable MEAs, used "in vivo", and non-implantable MEAs, used "in vitro". Context_7 : A vision chip is an integrated circuit having both image sensing circuitry and image processing circuitry on the same die. The image sensing circuitry may be implemented using charge-coupled devices, active pixel sensor circuits, or any other light sensing mechanism. The image processing circuitry may be implemented using analog, digital, or mixed signal (analog and digital) circuitry. One area of research is the use of neuromorphic engineering techniques to implement processing circuits inspired by biological neural systems. The output of a vision chip is generally a partially processed image or a high level information signal revealing something about the observed scene. Although there is no standard definition of a vision chip, the processing performed may comprise anything from processing individual pixel values to performing complex image processing functions and outputting a single value or yes/no signal based on the scene. Context_8 : Electronic music is music that employs electronic musical instruments, digital instruments and circuitry-based music technology. An electronic musician is a musician who composes or performs such music. In general, a distinction can be made between sound produced using electromechanical means, such as violins and drums, and that produced using electronic technology. Electromechanical instruments include mechanical elements, such as strings, hammers, and so on, and electric elements, such as magnetic pickups, power amplifiers and loudspeakers. Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, and the electric guitar, which are typically made loud enough for performers and audiences to hear with an instrument amplifier and speaker cabinet. Pure electronic instruments do not have vibrating strings, hammers, or other sound-producing mechanisms. Devices such as the theremin, sound synthesizer, and computer can produce electronic sounds. Context_9 : Moog is a 2004 documentary film by Hans Fjellestad about electronic instrument pioneer Dr. Robert Moog. The film features scenes of Dr. Moog interacting with various musical artists who view Moog as an influential figure in the history of electronic music. Context_10 : In mathematics and digital electronics, a binary number is a number expressed in the binary numeral system or base-2 numeral system which represents numeric values using two different symbols: typically 0 (zero) and 1 (one). The base-2 system is a positional notation with a radix of 2. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by almost all modern computers and computer-based devices. Each digit is referred to as a bit. fact_1 : Moog is a 2004 documentary film by Hans Fjellestad about electronic instrument pioneer Dr. Robert Moog. fact_2 : An electronic musical instrument is a musical instrument that produces sound using electronic circuitry and/or digital devices. Question: Who produced the documentary film Moog in 2004, about a pioneer of sound using electronic circuitry and digital devices?
