In one embodiment, a computer system includes a first component configured to output data on a bus in response to a request for data from a second component. A crystallization degree of an adhesive surface with the polymer layer in the substrate is smaller than a crystallization degree of an interior of the substrate. The flexible portion may be formed of a polyester film material such as a biaxially-oriented polyethylene terephthalate film, which may be at least partially transparent. The received requested media may be received from a cellular broadcast service, the cellular service andor a VHFUHF broadcast service. Apertures in the radial walls form inputs and outputs between adjacent chambers for the components to be mixed. Typically, no client data is transmitted to the remote monitoring site.
