A camera controller incorporates a microcontroller for carrying out all controller functions. The razor blade head assemblies include an elongated in-line main handle having opposed upper and lower ends and opposed front and rear faces supports; additionally, the system includes a shorter in-line arm having opposed upper and lower ends, and opposed front and rear faces. The thermally conductive region may aid in the extraction of heat resulting from light absorption in the wavelength-converting region, which, if excessive, may impair device operation. Moreover, the method includes providing one or more sniffers that are adapted to interact with a wireless medium.
