Various embodiments comprise light recycling films comprising an array of parallel ridges and grooves that form prisms that selectively reflect or transmit light. In one example, the method comprises at least one processor generating a computation graph comprising static computation nodes, dynamic computation nodes, and computation edges. The flap lid ensures the receiving opening defined in the front cover of a computer enclosure in a substantially closed condition to effectively prevent invasion of dusts and oily smokes. The heater assembly is slidably coupled to the support frame assembly between an operational position and a non-operational position.
