In the Cartesian coordinate system $xOy$, the parametric equation of line $l$ is $$\begin{cases} x= \frac {1}{2}t \\ y=1- \frac { \sqrt {3}}{2}t \end{cases}$$ (where $t$ is the parameter). With the origin as the pole and the positive x-axis as the polar axis, the polar equation of circle $C$ is $\rho=2\sin\theta$.  
(Ⅰ) Determine the number of intersection points between line $l$ and circle $C$;  
(Ⅱ) If circle $C$ intersects line $l$ at points $A$ and $B$, find the length of segment $AB$.
