TX (handheld)
The Palm TX (written as "Palm T, X" in official documentation) was a personal digital assistant which was produced by Palm, Inc. It was announced and released as part of Palm's October 2005 product cycle, and was in production until March 2009. Hardware Prior to its official announcement, a prototype was photographed with palmOne branding, labeled the "Tungsten XX".

Palm, Inc
Palm, Inc., was an American company that specialized in manufacturing personal digital assistants (PDAs) and developing software. Palm designed the PalmPilot, the first PDA successfully marketed worldwide, and was known for the Treo 600, one of the earlier successful smartphones. Palm developed the Palm OS software for PDAs and smartphones released under its line of Palm (PDA), Palm-branded devices and also licensed to other PDA manufacturers. The company was also responsible for the first versions of webOS, the first multitasking operating system for smartphones, and enyo (software), enyo.js, a framework for HTML5 apps. In July 2010, Palm was purchased by Hewlett-Packard (HP), and in 2011 announced a new range of webOS products. However, after poor sales, HP CEO Léo Apotheker announced in August 2011 that it would end production and support of Palm and webOS devices, marking the end of the Palm brand after 19 years. In October 2014, HP sold the Palm trademark to a shelf corpor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battery (electricity)
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons. When a battery is connected to an external electric load, those negatively charged electrons flow through the circuit and reach the positive terminal, thus causing a redox reaction by attracting positively charged ions, or cations. Thus, higher energy reactants are converted to lower energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary (single-use or "disposable") batteries are used once and discarded, as the electrode mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Personal Digital Assistant
A personal digital assistant (PDA) is a multi-purpose mobile device which functions as a personal information manager. Following a boom in the 1990s and 2000s, PDAs were mostly displaced by the widespread adoption of more highly capable smartphones, in particular those based on iOS and Android (operating system), Android in the late 2000s, and thus saw a rapid decline. A PDA has an electronic visual display. Most models also have audio capabilities, allowing usage as a portable media player, and also enabling many of them to be used as telephones. By the early 2000s, nearly all PDA models had the ability to access the Internet, intranets or extranets via Wi-Fi or wireless WANs, and since then generally included a web browser. Sometimes, instead of buttons, later PDAs employ touchscreen technology. History The first PDA, the Psion Organiser, Organiser, was released in 1984 by Psion (company), Psion, followed by Psion Series 3, Psion's Series 3, in 1991. The latter began to ...

Tungsten T5
The Tungsten series was Palm, Inc.'s line of business-class Palm OS-based PDAs. Details The Tungsten series was introduced in October 2002, created as a "prosumer" line priced at $199 to $300 to compete with the popular Sony Clie and Windows Mobile PDAs. The first device in the line is the Tungsten T, making it the first Palm PDA to be labeled with a letter rather than a number and to run Palm OS 5. All of the Tungsten PDAs have a few attributes in common: * 65,536 color LCD touch screen with a minimum 320 x 320 pixel resolution * metal or metal-toned enclosure * available flip cover to protect the screen * Secure Digital (SD) card slot with SDIO for memory cards and accessories * no built-in camera All models except the Tungsten C, W, and E have built-in Bluetooth wireless capabilities, while the Tungsten C and TX feature built-in Wi-Fi connectivity. Furthermore, by using the optional Palm Wi-Fi Secure_Digital#SDIO_cards Card accessory, the T3, T5, and E2 can also gain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thin Film Transistor Liquid Crystal Display
A thin-film-transistor liquid-crystal display (TFT LCD) is a type of liquid-crystal display that uses thin-film-transistor technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments. TFT LCDs are used in television sets, computer monitors, mobile phones, video game systems, personal digital assistants, navigation systems, projectors, and dashboards in some automobiles and in medium to high end motorcycles. History In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA, implemented Wallmark's ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crysta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Random Access Memory
Random-access memory (RAM; ) is a form of electronic computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks and magnetic tape), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. In today's technology, random-access memory takes the form of integrated circuit (IC) chips with MOS (metal–oxide–semiconductor) memory cells. RAM is normally associated with volatile types of memory where stored information is lost if power is removed. The two main types of volatile random-access semiconductor memory are static ...

Intel XScale
XScale is a microarchitecture for central processing units initially designed by Intel implementing the ARM architecture (version 5) instruction set. XScale comprises several distinct families: IXP, IXC, IOP, PXA and CE (see more below), with some later models designed as system-on-a-chip (SoC). Intel sold the PXA family to Marvell Technology Group in June 2006. Marvell then extended the brand to include processors with other microarchitectures, like Arm's Cortex. The XScale architecture is based on the ARMv5TE ISA without the floating-point instructions. XScale uses a seven-stage integer and an eight-stage memory super- pipelined microarchitecture. It is the successor to the Intel StrongARM line of microprocessors and microcontrollers, which Intel acquired from DEC's Digital Semiconductor division as part of a settlement of a lawsuit between the two companies. Intel used the StrongARM to replace its ailing line of outdated RISC processors, the i860 and i960. All the generatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithium-ion
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible Intercalation (chemistry), intercalation of Li+ ions into electronically Electrical conductor, conducting solids to store energy. Li-ion batteries are characterized by higher specific energy, energy density, and Energy efficiency (physics), energy efficiency and a longer cycle life and calendar life than other types of rechargeable batteries. Also noteworthy is a dramatic improvement in lithium-ion battery properties after their market introduction in 1991; over the following 30 years, their volumetric energy density increased threefold while their cost dropped tenfold. In late 2024 global demand passed per year, while production capacity was more than twice that. The invention and commercialization of Li-ion batteries Timeline of historic inventions, has had a large impact on technology, as recognized by the 2019 Nobel Prize in Chemistry. Li-ion batteries have enabled portable consumer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
