Devices and methods to facilitate escape from a venue with a sudden hazard
First Claim
1. A method of planning escape from a threat in a venue comprising:
- operating a machine learning system implemented on a first processor with a machine learning model subsequent to the detection of the threat to produce a plan of escape from the venue, wherein;
(a) the model has been pre-trained in a first step on a second processor with data concerning at least one of layout of venues, methods of escape from venues, and behavior of persons attempting to escape from a venue in a hazardous condition;
(b) the model has been transferred to one of the first processor and a third processor subsequent to the first step and prior to entry into the venue by a person;
(c) the model has been trained in a second step subsequent to the transfer and subsequent to entry into the venue by the person on one of the first processor and the third processor with data gathered subsequent to the entry with a sensor concerning at least one of a location of the person in the venue and behavior of persons attempting to escape from the venue; and
(d) the model subsequent to the second step is used to produce the plan of escape;
(e) the first processor has a memory containing a program to use the machine learning model to produce an instruction to escape from the venue subsequent to the detection of a hazard in the venue; and
(f) using an output device guides the person in escape from the venue.

Abstract
A device and associated methods for escaping from a venue when a threat is detected is described. Venues can be buildings or outside areas and contain the area where the threat constitutes a hazard to a protected person. Threats include fire, terrorists, gunmen, explosion, collapse, loss of critical resources and crowd panic. The device incorporates a machine learning system implemented with a neural network or other pattern matching system and is trained in steps. Pre-training is based on general requirements such as edge-detection and audio analysis. Principles and data for venue layouts and human behavior can be included. The produced model is further trained from data gathered from sensors and servers after entry into the venue. Operation of the model produces warnings of threats and a plan of escape with steps of the plan communicated to the protected person by audio, visual or tactile sensory channels.
