Handspring Visor
Handspring, Inc., was an American electronics company founded in 1998 by the founders of Palm, Inc., after they became dissatisfied with the company's direction under the new owner 3Com. The company developed Palm OS–based Visor- and Treo-branded personal digital assistants. In 2003, the company merged with Palm, Inc.'s hardware division. History The company was founded in June 1998 by Jeff Hawkins, Donna Dubinsky, and Ed Colligan, the original inventors of the PalmPilot and founders of Palm, Inc., after they became unhappy with the direction of the company after its acquisition by 3Com. Their Visor line of PDAs synced by USB, which was significantly faster than Palm's RS232 serial sync. The Springboard expansion slot provided GPS navigation, cameras, music players, cell phone service, and most of the functions of a "smart phone". In June 2000, during the dot-com bubble, the company became a public company via an initial public offering. The company's shares, which were list ...

NASDAQ
The Nasdaq Stock Market (; National Association of Securities Dealers Automated Quotations) is an American stock exchange based in New York City. It is the most active stock trading venue in the U.S. by volume, and ranked second on the list of stock exchanges by market capitalization of shares traded, behind the New York Stock Exchange. The exchange platform is owned by Nasdaq, Inc. (which the exchange also lists; ticker symbol NDAQ), which also owns the Nasdaq Nordic stock market network and several U.S.-based stock and options exchanges. Although it trades stock of healthcare, financial, media, entertainment, retail, hospitality, and food businesses, it focuses more on technology stocks. The exchange is made up of both American and foreign firms, with China and Israel being the largest foreign sources.

Motorola
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 h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lithium-ion Battery
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li+ ions into electronically conducting solids to store energy. Li-ion batteries are characterized by higher specific energy, energy density, and 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 has had a large impact on technology, as recognized by the 2019 Nobel Prize in Chemistry. Li-ion batteries have enabled portable consumer electronics, laptop computers, cellular phones, and electric cars. Li-ion batteries also see signifi ...

8-bit Color
8-bit color graphics are a method of storing image information in a computer's memory or in an image file, so that each pixel is represented by 8 bits (1 byte). The maximum number of colors that can be displayed at any one time is 256 per pixel or 28. Color quantization In order to turn a true color 24-bit image into an 8-bit image, the image must go through a process called color quantization. Color quantization is the process of creating a color map for a less color dense image from a more dense image. The simplest form of quantization is to simply assign 3 bits to red, 3 bits to green and 2 bits to blue, as the human eye is less sensitive to blue light. This creates a so called 3-3-2 8-bit color image, arranged like on the following table: Bit 7 6 5 4 3 2 1 0 Data R R R G G G B B This process is sub optimal. There could be different groupings of colors that make evenly spreading the colors out inefficient and likely to misrepresent the actual image. A ...

IrDA
IrDA is a wireless standard designed for exchanging data using infrared (IR). Infrared ports for this purpose have been implemented in portable electronic devices such as mobile telephones, laptops, cameras, printers, and medical devices. The main characteristics of this kind of wireless optical communication are physically secure bidirectional data transfer, line-of-sight and very low bit error rate, using point-and-shoot principles. IrDA has been made dormant by newer improved technologies like Bluetooth. History and usage The protocols and specifications of the standard were developed by the Infrared Data Association (abbreviated IrDA, giving the name to the standard itself), an industry-driven interest group that was founded in 1994 by around 50 companies. IrDA was popular on PDAs, laptops and some desktops from the late 1990s through the early 2000s. However, it has been displaced by other wireless technologies such as Bluetooth, and Wi-Fi, favored because they don't ne ...
