The invention provides an image capture system, apparatus and method for capturing a biometric image in high ambient light environments. Reflections from ambient light can introduce unwanted environmental pattern noise that can interfere with extracting information from a captured biometric image. The invention performs attenuation of ambient light without requiring employment of shielding to prevent ambient light from reflecting off of a surface being imaged. As a result, the invention can be deployed into environments with varied indoor or outdoor lighting characteristics.

A method () for limiting transmission power of a communication device () having a plurality of transceivers (). The method can include determining a desired maximum transmission power and determining a plurality of power contribution factors. Each of the power contribution factors can be associated with a respective one of the transceivers. The method also can include determining an expected transmission power based on, at least in part, a sum of the power contribution factors. Further, responsive to the expected transmission power exceeding the desired maximum transmission power, the power contribution for at least one of the transceivers can be selectively reduced or terminated.

A mobile station () that includes a transceiver () that receives an alert request () and a controller (). Responsive to the alert request, the controller can enter the mobile station into an alert active mode in which an alert signal is generated on the mobile station. Responsive to not receiving an acknowledgement to the alert signal within a defined period, the controller can enter the mobile station into an alert sleep mode in which at least one parameter of the alert signal is changed. Further, the controller can awake the mobile station from the alert sleep mode in response to detecting a user presence. The mobile station further can include an accelerometer () and/or a positioning system () that detect the user presence by detecting movement of the mobile station.
