Abstract: Technologies are provided herein for modeling and tracking physical objects, such as human hands, within a field of view of a depth sensor. A sphere-mesh model of the physical object can be created and used to track the physical object in real-time. The sphere-mesh model comprises an explicit skeletal mesh and an implicit convolution surface generated based on the skeletal mesh. The skeletal mesh parameterizes the convolution surface and distances between points in data frames received from the depth sensor and the sphere-mesh model can be efficiently determined using the skeletal mesh. The sphere-mesh model can be automatically calibrated by dynamically adjusting positions and associated radii of vertices in the skeletal mesh to fit the convolution surface to a particular physical object.

Abstract: Embodiments of a system and a method for continuously measuring cementitious board during the continuous manufacture thereof can be used in connection with the manufacture of various cementitious products, including gypsum wallboard, for example. Embodiments of a system and a method for continuously measuring cementitious board during its continuous manufacture can be used online in a continuous manufacturing process to effectively determine the degree to which cementitious slurry has set (e.g., expressed as percent hydration) at a predetermined location, such as, near a cutting station, for example. A height measuring system can be used to determine the relative amount the cementitious board sags as it passes over an unsupported span disposed between the forming station and the cutting station and to correlate the measured sag distance with a value of percent hydration of the cementitious slurry of that particular portion of the cementitious board.
