Abstract: Disclosed are various approaches for automatically assigning weights to vertices of a skin or mesh that control how said vertices in the 3D model move under the influence of skeletal rotation and translation. A computing device can receive a first model weightings matrix. Next, the computing device can include adjusting the number of rows in the first model weightings matrix to generate an adjusted model weightings matrix with a number of rows that matches an input number of rows for a machine-learning model, each row in the adjusted model weightings matrix representing a vertex of a mesh applied to a three-dimensional model. Then, the computing device can apply the machine learning model to the adjusted model weightings matrix, to generate an output polygonal mesh model weightings matrix.

Abstract: A panel system includes a chassis holding one or more tray arrangements, which are each configured to receive one or more cassettes at two or more bays. The tray arrangements and cassettes cooperate to define a cassette sensor arrangement and a port occupancy sensor arrangement having separate interface points. The cassette sensor arrangement may include electronic memory storing physical layer information about the cassette. All active components of the port occupancy sensor arrangement are disposed on the tray while the electronic memories of the cassette sensor arrangement are stored on the cassettes.

Abstract: Bulk single crystal of aluminum nitride (AlN) having an areal planar defect density?100 cm?2. Methods for growing single crystal aluminum nitride include melting an aluminum foil to uniformly wet a foundation with a layer of aluminum, the foundation forming a portion of an AlN seed holder, for an AlN seed to be used for the AlN growth.

Abstract: In various embodiments, non-zero thermal gradients are formed within a growth chamber both substantially parallel and substantially perpendicular to the growth direction during formation of semiconductor crystals, where the ratio of the two thermal gradients (parallel to perpendicular) is less than 10, by, e.g., arrangement of thermal shields outside of the growth chamber.

Abstract: The present invention relates to a post support device (1) for a post (10) adapted to be inserted substantially vertically in the ground. The post (10) has a top end (10A) and a bottom end (10B). The support device comprises a support member (2,3) adapted to engage the post below ground level at a point remote from the post bottom end, and at least two pairs of fins (2A,2B; 3A,3B), each pair of which extend from and form a triangulated structure with the support member and/or post. In use, with the post with the support device attached thereto is inserted substantially vertically in the ground, and the fins provide lateral resistance to prevent the post from displacing the soil and tilting towards the horizontal.

Abstract: A system is provided for capturing energy from heat expelled in an exhaust of an engine of a motor vehicle and storing the captured energy. The system comprises a generator, a condenser, an evaporator, and an absorber. The generator captures heat from the exhaust of the engine and may be configured for circulating a first solution having a solute that is vaporizable by heat captured by the generator. The condenser may be coupled to the generator for receiving vaporized solute and condensing the vaporized solute to a liquid. The evaporator may be coupled to the condenser and have an orifice between the condenser and the evaporator. The evaporator may have a first fluid passage for circulating the solute and a second fluid passage for circulating a second solution. The first and second fluid passages may be configured such that solute running through the first fluid passage is vaporizable by heat absorbed from the second solution running through the second fluid passage, thereby cooling the second solution.
