Abstract: One possible system may include a detector, a food scale, a water scale, a facial camera, and a processor. The detector may recognize a presence or absence the animal. The food scale may determine a weight of food in a food tray. The water scale may determine a weight of water in a water tray. The facial camera may observe a face of the animal when the animal is feeding or drinking. The processor may determine, upon an indication that the animal is present, and the face of the animal observed by the facial camera, an identity of the animal. The processor may additionally determine via the food scale, upon an indication that the animal is absent, an amount of food consumed by the animal. The processor may moreover determine via the water scale, upon an indication that the animal is absent, an amount of water consumed by the animal.

Abstract: The current invention provides a virtual world simulation system capable of hosting with massive amount of concurrent players by integrating commodity parallel co-processors into servers. The current invention proposes novel parallel processing algorithms to make use of commodity parallel co-processors like a graphic processing unit (GPU) or any specialized hardware with parallel architecture design like a field-programmable gate array (FPGA), to accelerate virtual world simulation.

Abstract: A method for streaming multi-LOD design feature of a 3D-CAD model comprises defining a LOD of a 3D-CAD model with each design feature of the 3D-CAD model, wherein the design feature is the smallest 3D-CAD model constructing unit; constructing the LOD of the 3D-CAD model into a decomposition data structure of LOD design feature recording each design feature of the 3D-CAD model in different LODs, wherein the LOD comprises all unit assembly faces of the design features; constructing a switch face display mechanism controlling whether each design feature of the 3D-CAD model is displayed; and encapsulating a designated design feature into a packet based on users' configuration and transmitting the packet.
