In an acute triangle ABC, sides $a$, $b$, $c$ are opposite to angles $\angle A$, $\angle B$, $\angle C$ respectively. The vectors $\overrightarrow{\mu}=(a^2+c^2-b^2, \sqrt{3}ac)$ and $\overrightarrow{v}=(\cos B, \sin B)$ are such that $\overrightarrow{\mu} \parallel \overrightarrow{v}$.
(I) Find the angle $B$;
(II) Determine the range of values for $\sin A + \sin C$.
