Abstract:
A system and method to detect acoustic signals from fire sprinkler heads discharging water and to locate such devices in a public building, airport, sports stadium or other structure which can include a system to measure speech intelligibility. Time and frequency domain analysis are carried out to establish the presence of signals characteristic of water discharge from a fire sprinkler.
Abstract:
A system and method to detect PASS-type device audio alarm signals and to locate such devices in alarm in a public building, airport, sports stadium or other structure which can include a system to measure speech intelligibility. Time and frequency domain analysis are carried out to establish the pressure of PASS-type device audio output signals.
Abstract:
A system for coordinating the activity of a plurality of humans in teams with a central automated controller having reasoning capability based on a predetermined set of criteria by sending messages to and from each of the humans. The controller processes input from each of the humans in accordance with programmed decision making capability to accomplish predetermined objectives and provide output to at least some of the humans to assess a situation, direct steps in response thereto and coordinate decisions based on a predetermined model and task assessment reasoning to determine the best way to accomplish the predetermined objectives. The coordinator assesses changes to the situation, and makes decisions about the various tasks to be performed and when they are to be begun. Outputs to the humans may be instructions, questions, information and combinations thereof.

Abstract:
A measurement system and method combine an audio announcement system with a plurality of spaced apart sensors to evaluate intelligibility of audio output from loudspeakers of the audio announcement system. Processing can take place at some or all of the sensors as well as at a common control element. Evaluations can be based on use of an appropriate speech intelligibility index method.
Abstract:
A measurement system and method combine an audio announcement system with a plurality of spaced apart wirelessly coupled devices which evaluate speech intelligibility of audio output from loudspeakers of the audio announcement system. Processing can take place at some or all of the devices as well as at a common control element. Evaluations can be based on use of a method which maps to a Common Intelligibility Scale.
