  • Audible indicators for optical code reading systems
    Patent number: 6332575
    Abstract: A system for reading optical codes, and more particularly to code reading systems with sound signal generators, modules a sound detector detects an ambient sound level in a vicinity of the system operator and the volume of the audible indicator is controlled in response to the detected ambient sound level. The sound may be produced by a transducer located in a raised rail adjacent the system operator. Various kinds of audio signals may be produced, for example, to distinguish the system's response from those of nearby optical code reading systems or to identify the kind of optical code symbology being read or its informational content.
