LCOS
Digital Light Processing – DLP, LCD, and LCoS rear projection
The most similar competing system to DLP is known as LCoS (liquid crystal on silicon), which creates images using a stationary mirror mounted on the surface of a chip, and uses a liquid crystal matrix (similar to a liquid crystal display) to control how much light is reflected. DLP-based television systems are also arguably considered to be smaller in depth than traditional projection television.

Wavelength selective switching – Liquid Crystal on Silicon (LCoS)
LCoS technology has enabled the introduction of more flexible wavelength grids which help to unlock the full spectral capacity of optical fibers. Even more surprising features rely on the phase matrix nature of the LCoS switching element. Features in common use include such things as shaping the power levels within a channel or broadcasting the optical signal to more than one port.

LCoS-based WSS also permit dynamic control of channel centre frequency and bandwidth through on-the-fly modification of the pixel arrays via embedded software

LCoS
‘Liquid crystal on silicon’ (‘LCoS’ or ‘LCOS’) is a micro-display technology developed initially for projection televisions but now used also in Wavelength Selective Switches, structured illumination and Near-eye displays

LCoS – History
General Electric first demonstrated a low-resolution LCoS display in the late 1970s. Starting in the late 1990s a number of companies attempted to develop products for both near-eye and projection applications.
LCoS – History
At the 2004 Consumer Electronics Show|CES, Intel announced plans for the large scale production of inexpensive LCoS chips for use in flat panel displays. These plans were cancelled in October 2004. Sony has made it to market (December 2005) with the Sony-VPL-VW100 or Ruby projector, using SXRD, 3 LCoS chips each with a native resolution of 1920×1080, with a stated contrast ratio of 15,000:1 using a dynamic iris.
LCoS – History
Whilst LCoS technology was initially touted as a technology to enable large-screen, high-definition, rear-projection televisions with very high picture quality at relatively low cost, the development of large-screen LCD and plasma display|plasma flat panel displays obsoleted rear projection televisions. As of October 2013, LCoS-based rear-projection televisions are no longer produced.
LCoS – History
Commercial implementations of LCoS technology include Sony’s Silicon X-tal Reflective Display|SXRD (Silicon X-tal Reflective Display) and JVC’s ‘D-ILA’ (Digital Direct Drive Image Light Amplifier). Every company which produces and markets LCoS rear-projection televisions uses three-panel LCoS technology,. Sony and JVC both produce and market front-projection displays that use three LCoS panels.
LCoS – History
Developers and manufacturers who have left the LCoS imaging market include: Intel, Philips, MicroDisplay Corporation (the only company to successfully bring to market a single-panel LCoS television ), S-Vision, Colorado Microdisplay, Spatialight, Syntax-Brillian.
LCoS – Display system architectures
There are two broad categories of LCoS displays: three-panel and single-panel
LCoS – Three-panel designs
Compared to three chip Digital Light Processing|DLP devices, where the light is separated into three components and then combined back, light is additionally polarized in LCoS devices. As a result, four beam splitters are needed (compared to two beam splitters for three chip DLP).
LCoS – One-panel designs
Micron’s FLCoS technology is another single panel RGB solution used in Handheld projectors|pico-projectors, and near-eye display applications.
LCoS – Pico Projectors, Near-eye and Head Mounted Displays
Whilst initially developed for large-screen projectors, LCoS displays have found a consumer niche in the area of Handheld projectors|pico-projectors, where their small size and low power consumption are well-matched to the constraints of such devices.

Coatzacoalcos
‘Coatzacoalcos’ is a major seaport|port city in the southern part of the Mexico|Mexican States of Mexico|state of Veracruz, on the Coatzacoalcos River. Coatzacoalcos comes from an indigenous word meaning Site of the Snake or Where the snake hides. The city serves as the municipal seat of the municipalities of Mexico|municipality of the same name.
Coatzacoalcos – Etymology
Coatzacoalcos, in Nahuatl, means The place where the snake hides. According to the legend, this is the place where the god Quetzalcoatl made his final journey to the sea around the year 999 and where he made his promise to return.
Coatzacoalcos – History
Coatzacoalcos lies within the Olmec heartland. Excavations in 2008 for a tunnel underneath the Coatzacoalcos River indicate a substantial pre-Hispanic population.
Coatzacoalcos – History
The San Martín Tuxlta is an active volcano lying northwest of Coatzcoalcos in the Sierra de los Tuxtlas. It erupted in 1664, in May 1793 with large ash falls and lava flows, and most recently in 1796.
Coatzacoalcos – History
The municipality of Coatzacoalcos was established 22 December 1881, with the town as its seat. In 1900 the town name was changed to ‘Puerto México’. In 1911 it was elevated to city, and in 1936 the name was changed to the current Coatzacoalcos.
Coatzacoalcos – History
On 23 July 1940, Coatzacoalcos welcomed refugees from the Spanish Civil War who sought asylum in Mexico after travelling across the Atlantic aboard the SS Santo Domingo.
Coatzacoalcos – History
Coatzacoalcos became a very important crossroads during the oil boom of the 1970s, connecting the Yucatán Peninsula and oil fields in Campeche to the rest of Mexico and to the port of Salina Cruz in Oaxaca on the Pacific coast.
Coatzacoalcos – Notable people
Coatzacoalcos is the birthplace of actress Salma Hayek; journalist María Antonieta Collins; and footballers Sergio Ramirez (footballer)|Sergio Ramirez who played for FC Ararat Yerevan in the Armenian Premier League, and José Arturo Rivas who plays for the Tigres de la UANL in the Primera División de México.
Pulmonary talcosis
‘Pulmonary talcosis’, less specifically referred to as ‘talcosis’, is a pulmonary disorder caused by talc.
Pulmonary talcosis
Talcosis can also arise from the injection of drugs intended for oral administration, as talc is present in many tablets and capsules that are abused intravenously, such as benzodiazepines, dextroamphetamine, and prescription narcotics.
Iolcos
‘Iolcos’ (; also rendered Iolkos or Iolcus ; Greek language|Greek: ??????) is an ancient city, a modern village and a former Communities and Municipalities of Greece|municipality in Magnesia (regional unit)|Magnesia, Thessaly, Greece
Iolcos – Mythology
According to ancient Greek mythology Aeson was the rightful king of Iolcos, but his half-brother Pelias usurped the throne. It was Pelias who sent Aeson’s son Jason and his Argonauts to look for the Golden Fleece. The ship Argo set sail from Iolcos with a crew of fifty demigods and princes under Jason’s leadership. Their mission was to reach Colchis in Kutaisi|Aea at the eastern seaboard of the Black Sea and reclaim and bring back the Golden Fleece, a symbol of the opening of new trade routes.
Iolcos – Mythology
Along with the Golden Fleece Jason brought a wife, the sorceress Medea, king Aeetes’ daughter, granddaughter of the Sun, niece of Circe, princess of Aea, and later queen of Iolcos, Corinth and Aea, and also murderer of her brother Absyrtus and her two sons from Jason, a tragic figure whose trials and tribulations were artfully dramatized in the much staged play by Euripides, Medea (play)|Medea.
Iolcos – Mythology
The place of ancient Iolcos is believed to be located in modern-day nearby Dimini, where a Mycenaean Greece|Mycenaean palace was excavated recently [http://www.arcl.ed.ac.uk/a1/stoppress/stop769.htm].
Chalcostigma
‘Chalcostigma’ is a genus of hummingbird in the family Trochilidae. The name of the genus is derived from the Ancient Greek|Greek khalkos meaning bronze and stigme for a spot or mark, a reference to the beard on the bronze-tailed thornbill.
