A mobile telephone () with a camera feature () that functions as a motion detection device. The mobile telephone can include an image capture software routine () and a motion detection software routine (). The image capture software routine can use the camera feature to automatically generate one or more time spaced images. The motion detection software routine can detect motion based upon differences between the time spaced images. The motion detection software routine can selectively utilize a multiple algorithms.

Utilizing a portable electronic device to detect motion

A method for masking a location ( ) of a mobile subscriber in a cellular communications network is disclosed. The subscriber location ( ) is masked by dividing a territory of cellular coverage into a grid ( ) of cells ( ) and dislocating the actual location ( ) to a center of a cell ( ) or to a point within a circle ( ).

A method ( ) for parameterizing a predetermined geographic area ( ) serviced by a satellite communication system ( ) into a number of equally shaped sub-partitions ( ) is discloseed. The satellite communication system ( ) has a processor ( )for generating data elements and a memory ( ) for storing the data elements in data structure. The method ( ) includes the step ( ) of determining a total latitude side length dimension and a total longitude side length dimension of the predetermined geographic area ( ) from latitude and longitude values representative of the geographic area. The steps ( ) also include determining the area of a sub-partition based upon the total latitude side length, the total longitude side length, and the number of equally shaped sub-partitions. Each of the sub-partitions ( ) are substantially square and have the same area. The steps also include determining ( ) an actual side latitude dimension ( ) of the sub-partition ( ) and storing the side latitude dimension ( ) in the data structure, and determining ( ) an actual side longitude dimension ( ) of the sub-partition ( ) and storing the side longitude dimension ( ) in the data structure. The satellite communication system ( ) generates a grid from the actual side latitude dimension ( ) and the actual side longitude dimension ( ) and superimposes the grid over the predetermined geographic area ( ).
