Cell Phone Trends for 2009

Facebook X LinkedIn Email
Some of the must-have features for 2009 in so-called "smart" phones -- think mobile computers that make calls -- include touch screens with "clickability," sophisticated accelerometers (which can sense when the phone is changed from portrait to landscape view and adjust the screen accordingly), full QWERTY keyboards, GPS capability, high-resolution cameras with flash, 3G networking and WiFi connectivity. The Palm Pre. (Image: Palm) One such feature-laden phone, one of most anticipated smart phones since its debut on the showroom floor at the Consumer Electronics Show (CES) in Las Vegas...Read full article

    accelerometer
    An accelerometer is a sensor or transducer that measures the rate of change of velocity of an object, or in simpler terms, it measures acceleration. Accelerometers are widely used in various electronic devices to detect and measure the acceleration forces acting on the device in different directions. Key features and principles of accelerometers include: Acceleration measurement: The primary function of an accelerometer is to measure acceleration, which is the rate of change of velocity...
    cell
    1. A single unit in a device for changing radiant energy to electrical energy or for controlling current flow in a circuit. 2. A single unit in a device whose resistance varies with radiant energy. 3. A single unit of a battery, primary or secondary, for converting chemical energy into electrical energy. 4. A simple unit of storage in a computer. 5. A limited region of space. 6. Part of a lens barrel holding one or more lenses.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
