BlackBerry Bold 9780
The BlackBerry Bold was a line of mid-range and high-end smartphones developed by BlackBerry Limited. The lineup was launched in 2008 with the BlackBerry Bold 9000. In 2009 the form factor was shrunk with the 9700 and the 9630. In 2010, the 9650 and 9780 wwas released with BlackBerry OS 6. In 2011, the 9780 was replaced by the 9790/9788 alongside the 9900/9930 series. The 9900/9930 and 9790, which have additional touchscreen displays, released in August and November 2011, respectively. The Bold family was known for its distinctive form factor, QWERTY keyboard, and typical BlackBerry messaging capabilities with a different keyboard than the Curve series. The Bold series was usually more expensive and had more expensive materials (e.g. leather, soft touch rubber, carbon fiber, metal) compared to the Curve (plastic, glossy), and had higher specifications. There were two basic form factors within the Bold line: the original larger size on the 9000 and 9900 Series and the "baby bold ...

Research In Motion
BlackBerry Limited, formerly Research In Motion (RIM), is a Canadian software company specializing in secure communications and the Internet of Things (IoT). Founded in 1984, it developed the BlackBerry brand of interactive pagers, smartphones, and tablets. The company transitioned to providing software and services and holds critical software application patents. Initially leading the mobile phone and pager industry in the 1980s and 90s, the company struggled to gain a lasting presence in the smartphone market of the new millennium. BlackBerry led the market in many countries, particularly the United States, until 2010, with the announcement of the iPhone 4. The company withered against the rapid rise of Apple and Android. After the troubled launch of the BlackBerry 10, it transitioned to a cybersecurity enterprise software and services company under CEO John S. Chen. In 2018, the last BlackBerry smartphone, the BlackBerry Key2 LE, was released. In 2022, BlackBerry dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Trackpad
An optical trackpad is an input device based on an optical sensor, which detects the displacement of a finger that is moving on top of it. The sensor is used typically in smartphones, where it replaces the D-pad, and in ultra-portable or ultra-mobile PCs, where it replaces touchpads, pointing sticks or trackballs as pointing device. The main advantages over a D-pad are: * It can track movements in 360 degrees and with varying speeds. * It uses space efficiently, without the need for small buttons that are difficult to press. Next to browsing through menus, it can drive a mouse cursor in point&click interfaces. In comparison with touchpad A touchpad or trackpad is a type of pointing device. Its largest component is a tactile sensor: an electronic device with a flat surface, that detects the motion and position of a user's fingers, and translates them to 2D motion, to control a Cu ...s, it detects actual skin displacement, instead of displacement of the center of the a ...

Blackberry Bold 9000
BlackBerry is a discontinued brand of handheld devices and related mobile services, originally developed and maintained by the Canadian company Research In Motion (RIM, later known as BlackBerry Limited) until 2016. The first BlackBerry device launched in 1999 in North America, running on the Mobitex network (later also DataTAC) and became very popular because of its "always on" state and ability to send and receive email messages wirelessly. The BlackBerry pioneered push notifications and popularized the practise of "thumb typing" using its QWERTY keyboard, something that would become a trademark feature of the line. In its early years, the BlackBerry proved to be a major advantage over the (typically) one-way communication pagers and it also removed the need for users to tether to personal computers. It became especially used in the corporate world in the US and Canada. RIM debuted the BlackBerry in Europe in September 2001, but it had less appeal there where text messaging us ...

Fixed-focus Lens
A photographic lens for which the focus is not adjustable is called a fixed-focus lens or sometimes focus-free. The focus is set at the time of lens design, and remains fixed. It is usually set to the hyperfocal distance, so that the depth of field ranges all the way down from half that distance to infinity, which is acceptable for most cameras used for capturing images of humans or objects larger than a meter. Rather than having a method of determining the correct focusing distance and setting the lens to that focal point, a fixed-focus lens relies on sufficient depth of field to produce acceptably sharp images. Most cameras with focus-free lenses also have a relatively small aperture, which increases the depth of field. Fixed-focus cameras with extended depth of field (EDOF) sometimes are known as full-focus cameras. Concept In order to reach a minimal focal distance, the aperture and the focal length of the lens are reduced (a slow wide-angle lens), to make the hyperfocal ...

CDMA
Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this without undue interference between the users, CDMA employs spread spectrum technology and a special coding scheme (where each transmitter is assigned a code). CDMA optimizes the use of available bandwidth as it transmits over the entire frequency range and does not limit the user's frequency range. It is used as the access method in many mobile phone standards. IS-95, also called "cdmaOne", and its 3G evolution CDMA2000, are often simply referred to as "CDMA", but UMTS, the 3G standard used by GSM carriers, also uses "wideband CDMA", or W-CDMA, as well as TD-CDMA and TD-SCDMA, as its radio technologies. Many carriers (such as AT&T, U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tethering
Tethering or phone-as-modem (PAM) is the sharing of a mobile device's cellular data connection with other connected computers. It effectively turns the transmitting device into a modem to allow others to use its cellular network as a gateway for Internet access. The sharing can be done wirelessly over wireless LAN (Wi-Fi), Bluetooth, IrDA or by physical connection using a cable like USB. If tethering is done over Wi-Fi, the feature may be branded as a personal hotspot or mobile hotspot, and the transmitting mobile device would also act as a portable wireless access point (AP) which may also be protected using a password. Tethering over Bluetooth may use the Personal Area Networking (PAN) profile between paired devices, or alternatively the Dial-Up Networking (DUN) profile where the receiving device virtually dials the cellular network APN, typically using the number ''*99''#. Mobile devices' OS support Many mobile devices are equipped with software to offer tethered Internet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near Field Communication
Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of or less. NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on a NFC-enabled device such as a smartphone. NFC communicating in one or both directions uses a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band, compliant with the ISO/IEC 18000-3 air interface standard at data rates ranging from 106 to 848 kbit/s. The NFC Forum has helped define and promote the technology, setting standards for certifying device compliance. Secure communications are available by applying encryption algorithms as is done for credit cards and if they fit the criteria for being considered a personal area network. NFC ...
