A method of managing timing alignment functionality in multiple component carriers for a communication device of a wireless communication system, which includes separately managing TA functionality of a plurality of component carriers or jointly managing TA functionality of component carriers belonging to the same cell. A first waveguide structure is configured to receive at least a portion of the one or more wavelengths and outputs a first optical beam. A quantizer receives the filter output signal and produces a quantized representation of the filter output signal. The second computing device may be inaccessible to the plurality of users, but accessible by a user account of the first computing device. The pistons are engageable with the pliable seal and are adapted for moving relative to the housing to control the diameter of a passage through the inner portion of the seal in response to the insertion of a surgical object. This additional processing can include the second pass of a two-pass separable filter implemented in software on a general-purpose CPU, and in particular can result in the generation of an image pyramid.
