Patent Images

1. A device to detect the location of an occupant, the device comprising:

  • a plurality of sensors positioned in a cluster to capture images from a common location in the environment, the images being transmittable as data;

    rules comparable with the data using a rules engine operable by a microcontroller with a processor and memory to produce results indicative of a condition of certain locations of the environment, the rules being included in the memory; and

    an interface through which the data is accessible;

    wherein at least part of the rules define an analysis of the data including;

    detecting a precedent image,detecting a subsequent image,comparing the precedent image with the subsequent image to detect a likelihood of disparity between the images,creating a detected object image based on the disparity between the images,comparing the detected object image to known image data acquired from one or more known physical objects to determine if the detected object is one or more known physical objects,generating the results of the analysis respective to the determination of whether the detected object is one or more known physical objects, the results being storable in memory, andcarrying out an action dependent upon the results;

    wherein the results are generated respective to the location in the environment;

    wherein an event is definable in the rules to relate to the determination of whether the detected object is one or more known physical objects;

    wherein the event is associable with the action;

    wherein the action occurs subsequent to detecting the event;

    wherein a plurality of locations are includable in the environment, each location of the plurality of locations being within a field of detection of at least one of the plurality sensors;

    wherein the field of detection of each sensor of the plurality of sensors is associated with a subset of the plurality of locations;

    wherein the microcontroller is in communication with a network using a network interface;

    wherein the images captured by each of the plurality of sensors are processed with an image stitching algorithm to create a seamless mosaic;

    wherein the seamless mosaic is viewable using the interface;

    wherein the results of the analysis performed by the rules engine are accessible using the interface;

    wherein the results of the analysis are includable in the seamless mosaic; and

    wherein the one or more known physical objects are definable in the rules by placing the one or more known physical objects in a location in the environment and capturing the known image data of the one or more known physical objects using at least one of the plurality of sensors.
