摘要： A system for simulating objects in a three dimensional virtual space, comprising a host computing node coupled to a network, padding spheres defined in the virtual space, one padding sphere fully encasing each cube in an octree; a plurality of objects, each object tracked for position in the virtual space. A visibility sphere associated with each object is provided, and at least one display, displaying objects in the virtual space. One of the objects becoming a target object, a search determines objects to be rendered in the display, identifying all padding spheres overlapped at least partially by the visibility sphere of the target object as candidate padding spheres, and identifying objects within or overlapping the candidate padding spheres, determining a visibility ratio for each object of maximum dimension of the object divided by distance from the target object, any object having a visibility to be rendered in the display.

摘要： An air conditioner shut-off system includes an overflow conduit that is coupled, at one end, to the drainage system of an air handler unit of the air conditioner system. The opposite end of the overflow conduit is positioned over an overflow container, which is suspended by a harness at the lower end of the harness. The upper end of the harness being operably coupled to the breaker throw of the main breaker, which is provided on or proximate to the air handler unit. If the drainage system becomes obstructed, water will flow into the overflow container through the conduit, and eventually the mass of the water accumulated in the overflow container will produce enough force acting on the breaker throw through the harness to flip the breaker throw to the OFF position and shut off the air conditioner system.

摘要： A light emitting device includes a p-type semiconductor layer, an n-type semiconductor layer, and an active region between the n-type semiconductor layer and the p-type semiconductor layer. A non-transparent feature, such as a wire bond pad, is on the p-type semiconductor layer or on the n-type semiconductor layer opposite the p-type semiconductor layer, and a reduced conductivity region is in the p-type semiconductor layer or the n-type semiconductor layer and is aligned with the non-transparent feature. The reduced conductivity region may extend from a surface of the p-type semiconductor layer opposite the n-type semiconductor layer towards the active region and/or from a surface of the n-type semiconductor layer opposite the p-type semiconductor layer towards the active region.
