According to an embodiment of the invention, a method and apparatus are described to receive a signal, determine a quality of the received signal, and transmit a power control message, with a selected size, to request a modification in transmission power, the power control message being based at least in part on the quality of the received signal. The thermally reversible viscosifying polymer of the WOW emulsion includes a block copolymer having at least a first polyoxyalkylene block having a hydrophobic region and a hydrophilic region effective to form micelles in solution in response to a change in temperature, and at least a second block comprising a poly. The speech server supports static grammars that do not change and dynamic grammars that may change after a commit. These third and fourth layers do not extend the full length of the blade to provide supplemental stiffness while avoiding excess bending stress. A heater trace is disposed on the first substrate layer with the first thermal sensor.
