A bicycle hub brake component is provided for braking a hub of a wheel mounted on a bicycle frame The component comprises a brake drum and a cooling disk. Further, according to certain non-limiting embodiments, the at least partial coating adapted to polarize at least transmitted radiation comprises at least one at least partially aligned dichroic material. The beam of the semiconductor laser is directed along the optical pathway and onto the adjustable mirror where the beam is reflected by the adjustable mirror onto the waveguide portion of the wavelength conversion device. The aperture is positioned relative to the character such that, when the finger is received by the at least one aperture, the finger appears as an appendage of the character. A controller is configured to compare the set of filter coefficients to the predetermined set of filter coefficient thresholds.
