A method and system are implemented for monitoring the thermal dissipation from a computer processing unit. Therefore, the manufacturing time and cost may be reduced. System software includes a real-time fire model, a layered smoke obscuration model, simulation of an extinguishing agent, and an interface to a zone fire model. If necessary, the signal transmitted by at least one of the synchronized transmitters may be delayed, such that identical digital signals received from at least two of the transmitters by receivers in the region will arrive at each receiver within a prescribed time window. Sharing access to the personal descriptor includes the use of a communications broker, rendering an animated personal descriptor and completing social and business interactions.
