US 12,224,726 B2 · Volume scaling and synchronization of tones

Abstract

A system, method and storage medium for providing an emergency alert includes reading tone, using one or more processors, information and volume level information corresponding to an emergency sound generator from memory coupled to the one or more processors; and controlling, using the one or more processors, an output sound of the emergency sound generator based on the tone information and volume level information. The tone information includes data of frequency variation over a predetermined period, and the volume level information includes data of volume level variation over the predetermined period.

Claims8

Dependent claims

A system for synchronizing a local node to a global time, comprising:

one or more processors, configured to:
receive a first time at which a main node transmits a first synch message including the first time;
determine a second time at which the local node receives the first synch message;
determine a difference between the first time and the second time;
receive a third time at which the main node transmits a second synch message including the third time;
determine a fourth time at which the local node receives the second synch message;
and
determine the global time by adding the first difference to the third time.
