Abstract: A Gated CDS Integrator (GCI) may amplify low-level signals without introducing excessive offset and noise. The GCI may also amplify the low level signals with accurate and variable gain. The GCI may include a modulator preceding an amplifier such that offset or noise present in a signal path between the modulator and a demodulator input is translated to a higher out of band frequency, and thereafter reduced by a double sampled discrete time integrator which also reduces thermal noise. The thermal noise may also be reduced by averaging the output of the discrete time integrator.

Abstract: A window covering can be configured as roll-up shade. The window covering can have a plurality of clips that are configured to be moveable from a first position in which the clips engage window covering material and a second position at which the clips do not engage the window covering material. When the clips are in the second position, the window covering material is manually adjustable from between a fully extended position to a retracted position. When the window covering material is moved to a retracted position, the lower portion of the window covering material may be rolled up upon height adjustment to form a roll of the window covering material. After the adjustment of the window covering material, the clips can be moved to their first position to engage the unrolled material to maintain a position of the rolled up material.
