RCA Photophone
RCA Photophone was the trade name given to one of four major competing technologies that emerged in the American film industry in the late 1920s for synchronizing electrically recorded audio to a motion picture image. RCA Photophone was an optical sound, "variable-area" film exposure system, in which the modulated area (width) corresponded to the waveform of the audio signal. The four other major technologies were the Warner Bros. Vitaphone sound-on-disc system, as well as three "variable-density" sound-on-film systems, Lee De Forest's Phonofilm, and Fox- Case's Movietone, and the German system Tri-Ergon. When Joseph P. Kennedy and other investors merged Film Booking Offices of America (FBO) with the Keith-Albee-Orpheum theater chain and Radio Corporation of America; the resulting movie studio RKO Radio Pictures used RCA Photophone as its primary sound system. In March 1929, RKO released ''Syncopation'', the first live-recorded film made with RCA Photophone. His ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mirror Galvanometer
A mirror galvanometer is an ammeter that indicates it has sensed an electric Current (electricity), current by deflecting a light beam with a mirror. The beam of light projected on a scale acts as a long massless pointer. In 1826, Johann Christian Poggendorff developed the mirror galvanometer for detecting electric currents. The apparatus is also known as a ''spot galvanometer'' after the spot of light produced in some models. Mirror galvanometers were used extensively in scientific instruments before reliable, stable electronic amplifiers were available. The most common uses were as recording equipment for seismometers and submarine communications cable, submarine cables used for telegraphy. In modern times, the term ''mirror galvanometer'' is also used for devices that move laser beams by rotating a mirror through a galvanometer set-up, often with a Servomechanism, servo-like control loop. The name is often abbreviated as ''galvo''. Kelvin's galvanometer The mirror gal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RKO Radio Pictures
RKO Radio Pictures Inc., commonly known as RKO Pictures or simply RKO, is an American film production and distribution company, historically one of the "Big Five" film studios of Hollywood's Golden Age. The business was formed after the Keith-Albee-Orpheum theater chain and Joseph P. Kennedy's Film Booking Offices of America studio were brought together under the control of the Radio Corporation of America (RCA) in October 1928. RCA executive David Sarnoff engineered the merger to create a market for the company's sound-on-film technology, RCA Photophone, and in early 1929 production began under the RKO name (an initialism of Radio-Keith-Orpheum). Two years later, another Kennedy concern, the Pathé studio, was folded into the operation. By the mid-1940s, RKO was controlled by investor Floyd Odlum. RKO has long been renowned for its cycle of musicals starring Fred Astaire and Ginger Rogers in the mid- to late 1930s. Actors Katharine Hepburn and, later, Robert Mitchu ...
