    Abstract: Techniques are described for injection molding. When material inside a cavity of a tool is solidified into a molded part, the tool imparts a finished surface onto the part, including sidewalls with a zero or low-draft angle. To allow separation from the cavity without using sleeves or sliders, the cavity is widened, just prior to the part being ejected. The tool is made from metal with a high coefficient of thermal expansion, so the size of the cavity can be manipulated using temperature control. Heat applied to an outer portion of the metal surrounding the cavity pulls the metal away from the part creating an air gap within the cavity. Carefully applied cooling to an inner portion of the metal blocks the heat and keeps the surface temperature under control, which preserves the finished surface on the part. When the air gap allows, the part releases from the cavity with the finished surface intact.

    Abstract: This application is directed to a surveillance camera system including a magnet mount for physically receiving a camera module. The camera module includes a housing having an exterior surface of a first shape. A surface of the magnet mount has a second shape that is substantially concave and complementary to the first shape, and is configured to engage the exterior surface of the housing of the camera module. A magnetic material is disposed inside the magnet mount and configured to magnetically couple to a magnetic material of the camera module. A friction pad is embedded on the surface of the magnet mount, has a substantially concave shape and protrudes beyond the second surface. The friction pad is configured to come into contact with the exterior surface of the housing of the camera module at least via a peripheral edge of the substantially concave friction pad.
