4.  The Accelerometer class dispatches events based on activity detected by the
device's motion sensor. This data represents the device's location or
movement along a 3-dimensional axis.

if(Accelerometer.isSupported){
accelerometer = new Accelerometer();
accelerometer.addEventListener(AccelerometerEvent.UPDATE,
updateHandler);
}
private function updateHandler (e:AccelerometerEvent):void{
trace(e.accelerationX);
trace(e.accelerationY);
trace(e.accelerationZ);
trace(e.timestamp)
}

8.  The Geolocation class dispatches events in response to the device's location
sensor.

9. var geolocation:Geolocation;
if(Geolocation.isSupported){
geolocation = new Geolocation();
if(!geolocation.muted){
geolocation.setRequestedUpdateInterval(10000);
geolocation.addEventListener(GeolocationEvent.UPDATE,updateHandler);
}
}
private function updateHandler(e:GeolocationEvent):void{
trace(e.longitude);
trace(e.latitude);
trace(e.altitude); //Other properties: heading, speed, timestamp
} //horizaontalAccuracy, VerticalAccuracy,

12.  CameraUI
 The CameraUI class allows you to capture a still image or video using the
default camera application on a device.
 CameraRoll
 The CameraRoll class allows you to access image data in the system media
library or "camera roll."

13. if (CameraUI.isSupported){
myCam = new CameraUI();
myCam.addEventListener(MediaEvent.COMPLETE, onComplete);
myCam.launch(MediaType.IMAGE);
}
if (CameraRoll.supportsBrowseForImage){
roll = new CameraRoll();
roll.addEventListener(MediaEvent.SELECT,onMediaSelect);
roll.browseForImage();
}

17.  The StageVideo object uses the device's hardware acceleration capabilities, if
available, to display live or recorded video in an application. Hardware
acceleration capabilities are available on most devices
