Assignee: WHELEN ENGINEERING COMPANY, INC.
Field: Control (Instruments)
Classification: CPC G  H | IPC H

Claim 12:
13. A system for providing an emergency sound alert, comprising:
one or more processors coupled to memory, configured to:
read volume level information corresponding to an emergency sound generator over a control area network (CAN) bus; and
scale an output of a resultant tone signal based on the volume level information;
control an output sound of the emergency sound generator based on the scaled resultant tone signal, and

wherein tone information includes data of frequency level variation over a predetermined or non-predetermined period, and the volume level information includes data of resultant volume levels;
wherein the resultant tone signal is a signal provided by mixing at least two tones, and each resulting volume level is a level upon which the resultant tone signal is based to be scaled; and
wherein the resultant volume level is provided in digital codes over the CAN bus, and each digital code is associated with a percentage to which the resultant tone signal is scaled.
