Dissipative system for increasing audio entropy thereby diminishing auditory perception
Through construction techniques, geometric design, and materials selection, audio entropy or randomness is introduced within an equipment structure or enclosure. This takes away the available sound energy by absorbing it or making it do work and dissipate before it can project audible sound outside the equipment structure or enclosure. “Damping” of the sound traveling through the equipment structure or enclosure is achieved by applying foam and/or fiberglass board/mat material to surfaces within the equipment structure or enclosure. By employing different material densities in the equipment structure or enclosure, sound levels at different frequencies can be diminished by not allowing them to pass through the structure or by greatly decreasing their amplitude. The semicircular sheathing within the equipment structure or enclosure that forms part of the airflow path refracts sound waves at different angles and does not make a good waveguide for transmitting the sound, which diminishes it. |

A battery for a vehicle has a plurality of battery cells forming a cell stack. During the operation of the battery, electrical energy can be drawn from the cell stack or supplied to the cell stack via at least one cable. At least one monitoring device, in particular an optocoupler, is used to monitor a resistance that is present on at least one detachable junction of the at least one cable to an additional component of the battery, wherein the monitoring device is connected in a parallel branch to the junction. By monitoring the resistance at the junctions, local overheating of the battery can be prevented. |
