IBM PCradio
The PCradio was a notebook computer released by International Business Machines (IBM) in late 1991. Designed primarily for mobile workers such as service technicians, salespersons and public safety workers, the PCradio featured a ruggedized build with no internal hard disk drive and was optioned with either a cellular or ARDIS RF modem, in addition to a standard landline modem. Components The internals of the PCradio were encased in a slate-gray, hardened plastic case, which IBM said was resistant to heat, moisture, impact and certain chemicals. Its port doors, connectors, and keyboard were designed to be water-resistant through the use of gaskets, seals, and O-rings. It featured a monochrome LCD capable of rendering graphics in CGA mode and text at 80 columns by 25 lines. The laptop was powered by either a nickel–cadmium battery or a wall or car power adapter. To keep the PCradio ruggedized, IBM offered SRAM modules of various capacities up to 2 MB for file storage, in l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Notebook (laptop)
A notebook computer or notebook is, historically, a laptop whose length and width approximate that of letter paper (). The term ''notebook'' was coined to describe slab-like portable computers that had a letter-paper footprint, such as Epson's HX-20 and Tandy's TRS-80 Model 100 of the early 1980s. The popularity of this form factor waned in the middle of the decade, as larger, clamshell-style laptops offered far more capability. In 1988, NEC's UltraLite defined a new category of notebook: it achieved IBM PC compatibility, making it technically as versatile as the largest laptops, while occupying a letter-paper footprint in a clamshell case. A handful of computer manufacturers followed suit with their own notebooks, including Compaq, whose successful LTE achieved full feature parity with laptops and spurred many others to produce their own notebooks. By 1991, the notebook industry was in full swing. Notebooks and laptops occupied distinct market segments into the mid-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Printer
Thermal printing (or direct thermal printing) is a digital printing process which produces a printed image by passing paper with a thermochromic coating, commonly known as thermal paper, over a print head consisting of tiny electrically heated elements. The coating turns black in the areas where it is heated, producing an image. Most thermal printers are monochrome (black and white) although some two-color designs exist. Grayscale is usually rasterized because it can only be adjusted by temperature control. Thermal-transfer printing is a different method, using plain paper with a heat-sensitive ribbon instead of heat-sensitive paper, but using similar print heads. Thermal transfer printer require the use of wax-based ribbons that adhere to the substrate during the printing process. As a result, users must load both labels and ribbon, essentially using an alternative ink system. Design A thermal printer typically contains at least these components: * Thermal head: Prod ...

Mobile Network Operator
A mobile network operator (MNO), also known as a mobile network provider, mobile network carrier, mobile , wireless service provider, wireless carrier, wireless operator, wireless telco, or cellular company, is a telecommunications provider of services that sells, delivers and maintains mobile telephony services to an end user. Overview A key defining characteristic of a mobile network operator is that it must own or control access to a radio spectrum license from a regulatory or government entity, and also that it must own or control the elements of the cellular network infrastructure necessary to provide services to subscribers over the licensed radio spectrum. In addition the operator would also contain other elements like the back haul infrastructure and provisioning computer systems. A mobile network operator typically also has the necessary provisioning, billing, and customer care computer systems, and the marketing, customer care, and engineering organizations need ...

McCaw Cellular Communications
McCaw Cellular Communications, Inc., was a cellular telephone pioneer in the United States. Savvy licensing of cellular spectrum in the early 1980s put McCaw Cellular in an extremely strong position, quickly outpacing the growth of the "Baby Bells" in the emerging market. The company purchased MCI Communications's mobile businesses in 1986, followed by LIN Broadcasting in 1989, giving them widespread access in all of the major US markets. Partnering with AT&T as a technology provider, McCaw introduced their "Cellular One" service in 1990, the first truly national cellular system. AT&T purchased 33% of the company in 1992, and arranged a merger in 1994 that made Craig McCaw one of AT&T's largest shareholders. In 2002, the company was spun off from AT&T to become AT&T Wireless Services. History McCaw Cellular Communications In 1966 J. Elroy McCaw sold one of his cable television holdings in Centralia, Washington to his three sons, including Craig who was 16 years old at the time. ...

Spango Valley
Spango Valley is a steep sided valley to the south-west of Greenock, Scotland. It runs approximately south west to north east for around from the confluence of the Spango Burn and Kip Water near Dunrod Farm, to Ravenscraig at the present day Aileymill Gardens.
