The present disclosure provides topical biophotonic materials and methods useful in phototherapy. The flat vibration motor includes a rotor portion, a stator portion, a fixing mount, a pair of terminals, and a base portion. After failure of the first controller, the method receives a second subset of the set of inputs from the second controller. Compensation for higher order reactive and thermal memory effects is embedded in the nonlinear dynamic compensation operation of the predistorter in an IIR filter bank. The supporting members 40 and 44 protrude into dead space relative to the position of the housing 20. The method may alternatively include performing the final software frame processing stage regardless as to whether a target framebuffer is available, performing all but final hardware frame processing stages regardless as to whether the target framebuffer is in use, and performing the final hardware processing stage if the target framebuffer is not in use.
