A method () and apparatus () generate an input signal based on the orientation of a device. A sensor () such as a camera, a gyro, or an accelerometer detects a change in device orientation and generates a position input signal that is provided to an application program () such as a game program, a text messaging program, or a user interface program to affect an operation thereof. The input signal can, for example, affects a navigation position associated with the application program.

Device orientation based input signal generation

A method for programming a wireless portable communication device ( ) over the air with a wireless communication network ( ). An end user may request to have his wireless portable communication device programmed or the device may be programmed to automatically request at a predetermined time interval. The communication network ( ) may remotely program an individual wireless portable communication device ( ), or may remotely program a group of wireless portable communication devices ( ).

Over-the-air programming method for wireless communication device

An apparatus for eliminating interference caused by spurious signals includes a reference oscillator (127) and a controller (114). Circuitry (500) in a communication device (104) incorporating the apparatus operates at a rate set by a system clock signal (CLOCK). The communication device (104) communicates on any one of a plurality of different channels. The reference oscillator (127) outputs the system clock signal (CLOCK) at a first frequency which generates spurious signals on at least one of the plurality of different channels. The controller (114) shifts the system clock signal (CLOCK) by a first predetermined amount to a second frequency when the communication device (104) is to be tuned to the at least one of the plurality of different channels so as to remove the spurious signals from the at least one of the plurality of different channels.
