Abstract: In general, the present disclosure is directed to an artificial window system that can simulate the user experience of a traditional window in environments where exterior walls are unavailable or other constraints make traditional windows impractical. In an embodiment, an artificial window consistent with the present disclosure includes a window panel, a panel driver, and a camera device. The camera device captures a plurality of image frames representative of an outdoor environment and provides the same to the panel driver. A controller of the panel driver sends the image frames as a video signal to cause the window panel to visually output the same. The window panel may further include light panels, and the controller may extract light characteristics from the captured plurality of image frames to send signals to the light panels to cause the light panels to mimic outdoor lighting conditions.

Abstract: A process for making silicon ingots using a multi-part, reusable, graphite crucible of at least two mold pieces configured for assembly into an open top mold having an interior surface functional as a mold cavity for receiving molten silicon; removing or reducing a prior applied release coating from the interior surface until a uniformly smooth finish is achieved; coating the interior surface with a first layer of release coating comprising silicon nitride; coating the interior surface with a second layer of release coat comprising silica suspended in water; coating the interior surface with a third layer of release coat comprising silicon nitride; curing the release coat on said crucible; casting a silicon ingot in the crucible; and then repeating the prior steps multiple times.

Abstract: A bulk silicon material for making silicon ingots, consisting of silicon pellets, and a method for making the pellets from an agglomerate-free source of high purity, ultra fine silicon powder by feeding a controlled amount of silicon powder into a pellet die, and dry compacting the powder at ambient temperature with pressure to produce a pellet that has a density of about 50-85% of the theoretical density of elemental silicon, a weight within a range of about 1.0 gram to about 3.0 grams, a diameter in the range of 10 mm to 20 mm and preferably of about 14 mm, and a height in the range of 5 mm to 15 mm and preferably of about 10 mm.
