Abstract: The present invention relates to a method for preparing an aqueous dispersion of acrylate-siloxane copolymer particles as described herein. The polymer particles comprise structural units of an acrylate monomer; an acid monomer; and a siloxane acrylate monomer of formula I: where R, R1, R2, Y and x are as defined herein. The method provides an efficient way to prepare a high solids content aqueous dispersion of siloxane-acrylate hybrid copolymers with efficient incorporation of siloxane acrylate monomers, low residual monomer, and low generation of unwanted coagulum. The dispersion is useful for forming coatings with improved hydrophobicity, stain resistance, and aesthetic/haptic properties compared with conventional all-acrylic compositions.

Abstract: This disclosure describes, in part, an audio/video (A/V) device that includes a first camera for generating first image data and one or more second cameras for both motion detection and generating second image data. For instance, the A/V device may generate and then store the second image data in one or more buffers. The A/V device may then detect an event, such as possible motion of an object. Based on detecting the event, A/V device may cause the one or more second cameras to cease generating the second image data and cause the first camera to begin generating the first image data. The A/V device may then process the second image data and send the processed second image data to a computing system. Next, the A/V device may process the first image data and send the processed first image data to the computing system.
