Abstract: This disclosure describes techniques for synchronizing data streams. In some instances, a computing device couples to multiple sensors, such as cameras, and applies accurate timestamp information to the individual frames of sensor data from the independent sensors. After aligning these data streams by applying these accurate timestamps, the computing device may, in some instances, encode and transmit these timestamped data streams to one or more entities for further processing. In one example, a first camera (e.g., a depth camera configured to generate a depth map) may capture images of an environment, as may a second camera (e.g., an Red-Green-Blue (RGB) camera configured to generate color images). The resulting images may be temporally aligned with one another via the timestamping, and the resulting aligned images from both the depth sensor and the RGB camera may be used to create a three-dimensional (3D) model of the environment.

Abstract: During operation, a facility may utilize many sensors, such as cameras, to generate sensor data. Some of these sensors may be housed within protective enclosures. The enclosures may be inside specially controlled environments, such as refrigerators, freezers, and so forth. During operation of the facility, moisture may accumulate on these enclosures, impairing the ability of the camera to acquire an image through the window. Described are devices to selectively heat a viewable area of the window such that moisture accumulation is reduced with minimal power use.
