Trium Mondo
The Trium Mondo is an early touchscreen smartphone designed and marketed by Trium, a Mitsubishi subsidiary, which runs the Windows Pocket PC 2000 operating system. The product was originally announced on January 10, 2000, at the Centre Georges Pompidou, Paris, and was released in the UK in August 2001. It featured dual-band GSM cellular connectivity, and was amongst the first devices released with GPRS support for data transfer. Screen and input The touchscreen on the Mondo is a 9.9 cm (3.9 in) passive-matrix monochrome liquid crystal display A liquid-crystal display (LCD) is a flat panel display, flat-panel display or other Electro-optic modulator, electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers.

Monophonic
Monaural or monophonic sound reproduction (often shortened to mono) is sound intended to be heard as if it were emanating from one position. This contrasts with stereophonic sound or ''stereo'', which uses two separate audio channels to reproduce sound from two microphones on the right and left side, which is reproduced with two separate loudspeakers to give a sense of the direction of sound sources. In mono, only one loudspeaker is necessary, but, when played through multiple loudspeakers or headphones, identical signals are fed to each speaker, resulting in the perception of one-channel sound "imaging" in one sonic space between the speakers (provided that the speakers are set up in a proper symmetrical critical-listening placement). Monaural recordings, like stereo ones, typically use multiple microphones fed into multiple channels on a recording console, but each channel is " panned" to the center. In the final stage, the various center-panned signal paths are usually mixed d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pocket PC 2000
Pocket PC 2000 (marketed as Pocket PC) was the first member of the Windows Mobile family of mobile operating systems that was released on April 19, 2000, and was based on Windows CE 3.0. It is the successor to the operating system aboard Palm-size PCs. Backwards compatibility was retained with such Palm-size PC applications. Pocket PC 2000 was intended mainly for Pocket PC devices, however several Palm-size PC devices had the ability to be updated also. Furthermore, several Pocket PC 2000 phones were released (under the name Handheld PC 2000), however at this time, Microsoft's "Smartphone" hardware platform had not yet been created. At this time, Pocket PC devices had not been standardized with a specific CPU architecture. As a result, Pocket PC 2000 was released on multiple CPU architectures, such as SH-3, MIPS, and ARM. The only resolution supported by this release was 240 x 320 (QVGA). Removable storage card formats that were supported were CompactFlash and MultiMediaCard. I ...

IrDA
The Infrared Data Association (IrDA) is an industry-driven interest group that was founded in 1994 by around 50 companies. IrDA provides specifications for a complete set of protocols for wireless infrared communications, and the name "IrDA" also refers to that set of protocols. The main reason for using the IrDA protocols had been wireless data transfer over the "last one meter" using point-and-shoot principles. Thus, it has been implemented in portable devices such as mobile telephones, laptops, cameras, printers, and medical devices. The main characteristics of this kind of wireless optical communication are physically secure data transfer, line-of-sight (LOS) and very low bit error rate (BER) that makes it very efficient. Specifications IrPHY The mandatory IrPHY (Infrared Physical Layer Specification) is the physical layer of the IrDA specifications. It comprises optical link definitions, modulation, coding, cyclic redundancy check (CRC) and the framer. Different data r ...

Centre Georges Pompidou
The Centre Pompidou (), more fully the Centre national d'art et de culture Georges-Pompidou ( en, National Georges Pompidou Centre of Art and Culture), also known as the Pompidou Centre in English, is a complex building in the Beaubourg area of the 4th arrondissement of Paris, near Les Halles, rue Montorgueil, and the Marais. It was designed in the style of high-tech architecture by the architectural team of Richard Rogers, Su Rogers, Renzo Piano, along with Gianfranco Franchini. It houses the Bibliothèque publique d'information (Public Information Library), a vast public library; the Musée National d'Art Moderne, which is the largest museum for modern art in Europe; and IRCAM, a centre for music and acoustic research. Because of its location, the centre is known locally as Beaubourg (). It is named after Georges Pompidou, the President of France from 1969 to 1974 who commissioned the building, and was officially opened on 31 January 1977 by President Valéry Giscard d'Esta ...

Liquid Crystal Display
A liquid-crystal display (LCD) is a flat panel display, flat-panel display or other Electro-optic modulator, electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but instead use a backlight or reflector (photography), reflector to produce images in color or monochrome monitor, monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden. For instance: preset words, digits, and seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character ...

Resistive Touchscreen
In electrical engineering, a resistive touchscreen is a touch-sensitive computer display composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. Description and operation There are two different types of metallic layers. The first type is called ''matrix'', in which striped electrodes on substrates such as glass or plastic face each other. The second type is called ''analogue'' which consists of transparent electrodes without any patterning facing each other. As of 2011 analogue offered lowered production costs. When contact is made to the surface of the touchscreen, the two sheets are pressed together. On these two sheets there are horizontal and vertical lines that, when pushed together, register the precise location of the touch. Because the touchscreen senses input from contact with nearly any object (finger, stylus/pen, palm) resistive touchscreens are a type of "passive" technology. For example, during the operation of ...

Mitsubishi Electric Products, Services And Standards
The is a group of autonomous Japanese multinational companies in a variety of industries. Founded by Yatarō Iwasaki in 1870, the Mitsubishi Group historically descended from the Mitsubishi zaibatsu, a unified company which existed from 1870 to 1946. The company was disbanded during the occupation of Japan following World War II. The former constituents of the company continue to share the Mitsubishi brand and trademark. Although the group of companies participate in limited business cooperation, most famously through monthly "Friday Conference" executive meetings, they are formally independent and are not under common control. The four main companies in the group are MUFG Bank (the largest bank in Japan), Mitsubishi Corporation (a general trading company), Mitsubishi Electric and Mitsubishi Heavy Industries (both diversified manufacturing companies). History The Mitsubishi company was established as a shipping firm by Iwasaki Yatarō (1834–1885) in 1870 under the name . I ...

Smartphones
A smartphone is a portable computer device that combines mobile telephone and computing functions into one unit. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software, internet (including web browsing over mobile broadband), and multimedia functionality (including music, video, cameras, and gaming), alongside core phone functions such as voice calls and text messaging. Smartphones typically contain a number of metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, include various sensors that can be leveraged by pre-included and third-party software (such as a magnetometer, proximity sensors, barometer, gyroscope, accelerometer and more), and support wireless communications protocols (such as Bluetooth, Wi-Fi, or satellite navigation). Early smartphones were marketed primarily towards the enterprise market, attempting to bridge the functionality of standalone perso ...
