MicroTAC
The MicroTAC is a series of cellular phones that was marketed by Motorola from 1989 until approximately 2000. The MicroTACs pioneered a new " flip" design in cellular handsets that was considered innovative and more compact compared to previous "brick" phones, such as Motorola's own DynaTAC line. The MicroTAC's design consisted of the "mouthpiece" being folded over the keypad. On later production models the "mouthpiece" was actually located in the base of the phone, along with the ringer. This set the standard and became the model for later clamshell design phones, which Motorola adopted in the StarTAC in 1996. The first MicroTAC model was released for analog networks, while later there were also GSM-compatible and TDMA/ Dual-Mode versions introduced in 1994. A CDMA MicroTAC was introduced in 1997. Early models MicroTAC 9800X The MicroTAC, released by Motorola on April 25, 1989, was the smallest and lightest phone available at the time. Upon its release, it made head ...

StarTAC
The StarTAC is a series of clamshell-style cellular mobile phones developed and marketed by Motorola beginning in 1996. The first notable flip phone, the original StarTAC model was uniquely at the time the size of a pager and weighed , making it the smallest and lightest cell phone up to that point. Officially, Motorola marketed the StarTACs as "wearable". The StarTAC's groundbreaking design was a development from Motorola's MicroTAC, a semi-clamshell design first launched in 1989. Whereas the MicroTAC's flip folded down from below the keypad, the StarTAC folded up from above the display. While often cited as the world's first clamshell/flip cell phone, NEC of Japan had already developed and released such a cell phone as early as 1991. Nevertheless, the StarTAC is considered the first example of a luxurious or fashionable cell phone. The earliest StarTAC models were made for analog AMPS networks while later digital GSM models were made for various markets, and the first Cdma ...

Clamshell Design
Clamshell design is a form factor commonly used in the design of electronic devices and other manufactured objects. It is inspired by the morphology of the clam. The form factor has been applied to handheld game consoles, mobile phones (where it is often called a "flip phone"), and especially laptop computers. Clamshell devices are usually made of two sections connected by a hinge, each section containing either a flat panel display or an alphanumeric keyboard/ keypad, which can fold into contact together like a bivalve shell. Generally speaking, the interface components such as keys and display are kept inside the closed clamshell, protecting them from damage and unintentional use while also making the device shorter or narrower so it is easier to carry around. In many cases, opening the clamshell offers more surface area than when the device is closed, allowing interface components to be larger and easier to use than on devices which do not flip open.

Motorola DynaTAC
The DynaTAC is a series of cellular telephones manufactured by Motorola from 1983 to 1994. Unveiled on March 6, 1983, the DynaTAC was the first commercially available handheld cellular phone. A full charge took roughly 10 hours, and it offered 30 minutes of talk time. It also offered a LED display for dialing or recall of one of 30 phone numbers. It was priced at US$3,995 in 1984, its commercial release year, equivalent to $ in . Several models followed, starting in 1985 with the 8000s and continuing with periodic updates of increasing frequency until 1993's Classic II. The DynaTAC was replaced in most roles by the much smaller MicroTAC when it was first introduced in 1989, and by the time of the StarTAC's release in 1996, it was obsolete. Name DynaTAC was an abbreviation of "Dynamic Adaptive Total Area Coverage". The TAC abbreviation would later also be used on the MicroTAC, StarTAC and TeleTAC lines of products.

Motorola MicroTAC II Platinum
Motorola, Inc. () was an American multinational telecommunications company based in Schaumburg, Illinois. It was founded by brothers Paul and Joseph Galvin in 1928 and had been named Motorola since 1947. Many of Motorola's products had been radio-related communication equipment such as two-way radios, consumer walkie-talkies, cellular infrastructure, mobile phones, satellite communicators, pagers, as well as cable modems and semiconductors. After having lost $4.3 billion from 2007 to 2009, Motorola was split into two independent public companies: Motorola Solutions (its legal successor) and Motorola Mobility (spun off), on January 4, 2011. Motorola designed and sold wireless network equipment such as cellular transmission base stations and signal amplifiers. Its business and government customers consisted mainly of wireless voice and broadband systems (used to build private networks), and public safety communications systems like Astro and Dimetra. Motorola's home and broadc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Form Factor (mobile Phones)
The form factor of a mobile phone is its size, shape, and style, as well as the layout and position of its major components. With one non-movable section Bar A bar (also known as a slab, block, candybar) phone takes the shape of a cuboid, usually with rounded corners and/or edges. The name is derived from the rough resemblance to a chocolate bar in size and shape. This form factor is widely used by a variety of manufacturers, such as Nokia and Sony Ericsson. Bar-type smartphones commonly have the screen and keypad on a single face. Sony had a well-known ' Mars Bar' phone model CM-H333 in 1993 that was longer and thinner than the typical bar phone. Bar phones without a full keyboard tend to have a 3×4 numerical keypad; text is often generated on such systems using the Text on 9 keys algorithm. Keyboard bars These are variants of bars that have a full QWERTY keyboard on the front. While they are technically the same as a regular bar phone, the keyboard and all the buttons ma ...

Nickel–metal Hydride Battery
A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium. NiMH batteries can have two to three times the capacity of NiCd batteries of the same size, with significantly higher energy density, although only about half that of lithium-ion batteries. They are typically used as a substitute for similarly shaped non-rechargeable alkaline batteries, as they feature a slightly lower but generally compatible cell voltage and are less prone to leaking. History Work on NiMH batteries began at the Battelle-Geneva Research Center following the technology's invention in 1967. It was based on sintered Ti2Ni+TiNi+x alloys and NiOOH electrodes. Development was sponsored over nearly two decades by Daimler-Benz and by Volkswa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
