Abstract: Systems and methods for audio power limiting based on thermal modeling are described. In some embodiments, a method includes monitoring a first temperature of a power die within an audio system; monitoring a second temperature of a digital die within the audio system; and using the first and second temperatures to limit an amplitude of an audio signal provided to a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) of an amplifier within the audio system to keep an operating temperature of the MOSFET under a thermal protection threshold without stopping the audio signal from being output by the audio system.

Abstract: This invention relates to a fluid disperser for a fire extinguishing system, and is specifically related to such kind of fluid dispersers which are adapted for electrical remote control. Such dispersers are provided with a striking mechanism adapted for breaking a safety device which closes the outlet for the fluid. The object of this invention is to show a construction by which it is ensured that the safety device is always fractured even by the use of a relatively weak striking mechanism and it is further the purpose of this invention to ensure that the path for the extinguishant is kept free after the fracturing of the safety device. For this purpose a displaceable striking pin and a loose counter-rest is used in connection with the striking mechanism so that the striking pin and the counter-rest will fall down as soon as the safety device is fractured thereby leaving the desired free passage for the extinguishant.
