Some context: John Logie Baird FRSE (; 13 August 1888 - 14 June 1946) was a Scottish engineer, innovator, one of the inventors of the mechanical television, demonstrating the first working television system on 26 January 1926, and inventor of both the first publicly demonstrated colour television system, and the first purely electronic colour television picture tube. In 1928 the Baird Television Development Company achieved the first transatlantic television transmission. Baird's early technological successes and his role in the practical introduction of broadcast television for home entertainment have earned him a prominent place in television's history.
Baird made many contributions to the field of electronic television after mechanical systems had taken a back seat. In 1939, he showed a system known today as hybrid colour using a cathode ray tube in front of which revolved a disc fitted with colour filters, a method taken up by CBS and RCA in the United States.  As early as 1940, Baird had started work on a fully electronic system he called the "Telechrome". Early Telechrome devices used two electron guns aimed at either side of a phosphor plate. The phosphor was patterned so the electrons from the guns only fell on one side of the patterning or the other. Using cyan and magenta phosphors, a reasonable limited-colour image could be obtained. He also demonstrated the same system using monochrome signals to produce a 3D image (called "stereoscopic" at the time). In 1941, he patented and demonstrated this system of three-dimensional television at a definition of 500 lines. On 16 August 1944, he gave the world's first demonstration of a practical fully electronic colour television display. His 600-line colour system used triple interlacing, using six scans to build each picture. Similar concepts were common through the 1940s and 50s, differing primarily in the way they re-combined the colours generated by the three guns. One of them, the Geer tube, was similar to Baird's concept, but used small pyramids with the phosphors deposited on their outside faces, instead of Baird's 3D patterning on a flat surface.  In 1943, the Hankey Committee was appointed to oversee the resumption of television broadcasts after the war. Baird persuaded them to make plans to adopt his proposed 1000-line Telechrome electronic colour system as the new post-war broadcast standard. The picture resolution on this system would have been comparable to today's HDTV (High Definition Television). The Hankey Committee's plan lost all momentum partly due to the challenges of postwar reconstruction. The monochrome 405-line standard remained in place until 1985 in some areas, and the 625-line system was introduced in 1964 and (PAL) colour in 1967. A demonstration of large screen three-dimensional television by the BBC was reported in March 2008, over 60 years after Baird's demonstration.
did he have any other patents?

Some context: William Randolph Hearst Sr. (; April 29, 1863 - August 14, 1951) was an American businessman, politician, and newspaper publisher who built the nation's largest newspaper chain and media company Hearst Communications and whose flamboyant methods of yellow journalism influenced the nation's popular media by emphasizing sensationalism and human interest stories. Hearst entered the publishing business in 1887 after being given control of The San Francisco Examiner by his wealthy father.
Beginning in 1919, Hearst began to build Hearst Castle, which he never completed, on a 240,000 acres (97,000 hectares) ranch at San Simeon, California, which he furnished with art, antiques and entire rooms brought from the great houses of Europe. He also used the ranch for an Arabian horse breeding operation. San Simeon was also used in the 1960 film Spartacus as the estate of Marcus Licinius Crassus (played by Laurence Olivier).  He also had a property on the McCloud River in Siskiyou County, in far northern California, called Wyntoon. Wyntoon was designed by famed architect Julia Morgan, who also designed Hearst Castle and worked in collaboration with William J. Dodd on a number of other projects.  In 1947, Hearst paid $120,000 for an H-shaped Beverly Hills mansion, (located at 1011 N Beverly Dr, Beverly Hills CA 90210) on 3.7 acres three blocks from Sunset Boulevard. This home, known as Beverly House, was once perhaps the "most expensive" private home in the U.S., valued at $165 million (PS81.4 million). It has 29 bedrooms, three swimming pools, tennis courts, its own cinema and a nightclub. Lawyer and investor Leonard Ross has owned it since 1976. The estate went on the market for $95 million at the end of 2010. The property had not sold by 2012 but was then listed at a significantly increased asking price of $135 million. The Beverly House, as it has come to be known, has some cinematic connections. It was the setting for the gruesome scene in the film The Godfather depicting a horse's severed head in the bed of film-producer, Jack Woltz. The character was head of a film company called International, the name of Hearst's early film company. According to Hearst Over Hollywood, John and Jacqueline Kennedy stayed at the house for part of their honeymoon. They watched their first film together as a married couple in the mansion's cinema. It was a Hearst-produced film from the 1920s.  In the early 1890s, Hearst began building a mansion on the hills overlooking Pleasanton, California on land purchased by his father a decade earlier. Hearst's mother took over the project, hired Julia Morgan to finish it as her home, and named it Hacienda del Pozo de Verona. After her death, it served as the clubhouse for Castlewood Country Club from 1925 to 1969, when it was destroyed in a massive fire.
