Zire Handheld
The Zire Series was Palm, Inc's "consumer-grade" brand of Personal Digital Assistant. Background/overview The lower-end models emphasized value—Palm's original Zire model was the first PDA under $100 from a major manufacturer—and the higher-end models emphasized multimedia capability, including features like cameras and audio playback functions suitable for listening to MP3s. Models Palm Zire and Palm Zire 21 The Palm Zire and Palm Zire 21 were inexpensive and are differentiated from the rest of Palm's line by having monochrome screens without backlighting, having only two application buttons instead of the typical four, and traditional up/down scroll buttons instead of the then-standard 5-way navigator found in other models. Both of these entry-level models are lightweight (3.8oz or 108g) and sport a white plastic face with a matte gray plastic back. The Zire (also known as the m150), released in the fourth quarter of 2002 and is the handheld responsible for starting the v ...

Camera
A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century. Cameras function through a combination of multiple mechanical components and principles. These include exposure control, which regulates the amount of light reaching the sensor or film; the lens, which focuses the light; the viewfinder, which allows the user to preview the scene; and the film or sensor, which captures the image. Several types of camera exist, each suited to specific uses and offering unique cap ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Super-twisted Nematic Display
An STN (super-twisted nematic) display is a type of liquid-crystal display (LCD). An LCD is a flat-panel display that uses liquid crystals to change its properties when exposed to an electric field, which can be used to create images. This change is called the twisted nematic (TN) field effect. Earlier TN displays twisted the liquid crystal molecules at a 90-degree angle. STN displays improved on that by twisting the liquid crystal molecules at a much greater angle, typically between 180 and 270 degrees. This allows for a sharper image and passive matrix addressing, a simpler way to control the pixels in an LCD. While STN displays were once common in various electronic devices, they have been largely replaced by TFT (thin-film transistor) displays. Development In 1982, C. M. Waters and E. P. Raynes patented STN displays, and by 1984 researchers at Brown Boveri (later ABB) built the first prototype STN matrix display, with 540 × 270 pixels. A key challenge was finding a w ...

Digital Camera
A digital camera, also called a digicam, is a camera that captures photographs in Digital data storage, digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film or film stock. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs. Digital and digital movie cameras share an optical system, typically using a Camera lens, lens with a variable Diaphragm (optics), diaphragm to focus light onto an image pickup device. The diaphragm and Shutter (photography), shutter admit a controlled amount of light to the image, just as with film, but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately afte ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Wi-Fi
Wi-Fi () is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for Wireless LAN, local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in small office/home office, home and small office networks to link devices and to provide Internet access with wireless routers and wireless access points in public places such as coffee shops, restaurants, hotels, libraries, and airports. ''Wi-Fi'' is a trademark of the Wi-Fi Alliance, which restricts the use of the term "''Wi-Fi Certified''" to products that successfully complete Interoperability Solutions for European Public Administrations, interoperability certification testing. Non-compliant hardware is simply referred to as WLAN, and it may or may not work with "''Wi-Fi Certified''" devices. the Wi-Fi Alliance consisted of more than 800 companies from ar ...

Zire 72
The Zire 72 is Palm, Inc.'s second Personal Digital Assistant with an integrated digital camera. Introduced in 2004, it is the replacement for the Zire 71, having a 1.2 megapixel camera, 32 MB of memory, built-in Bluetooth wireless communication, video recording and playback capability, a built-in microphone, hi-res hi-color screen, SecureDigital smartcard slot, and a 312 MHz Intel PXA270 processor. Users have complained about several problems, most notably *Blue paint peels off (a "special edition" version has been released that has no blue paint, just silver.) *Camera quality (broken pixels, uncovered lens etc.) *Screen whining *Battery life Palm, Inc. released a second version of the Zire 72, the Zire 72s, which is silver. This change fixed the problem with the paint. They subsequently released a version of the blue Zire 72, which used a different paint, and does not peel. As with other Bluetooth enabled devices, turning that connectivity off when not required, extend ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

SD Card
Secure Digital (SD) is a proprietary, non-volatile, flash memory card format developed by the SD Association (SDA). Owing to their compact size, SD cards have been widely adopted in a variety of portable consumer electronics, including digital cameras, camcorders, video game consoles, mobile phones, action cameras, and camera drones. The SD format was introduced in August 1999 by SanDisk, Panasonic (then known as Matsushita), and Kioxia (then part of Toshiba). It was designed as a successor to the MultiMediaCard (MMC) format, introducing several improvements aimed at enhancing usability, durability, and performance, which contributed to its rapid emergence as an industry standard. To manage the licensing and intellectual property rights related to the format, the three companies established SD-3C, LLC. In January 2000, they also founded the SDA, a non-profit organization dedicated to developing and promoting SD card standards. As of 2023, the SDA includes approxima ...

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 ...
