  • SYSTEMS, DEVICES, AND METHODS FOR MONITORING AND CONTROLLING A CONTROLLED SPACE
    Publication number: 20140226867
    Abstract: A computer-implemented method for monitoring and controlling a controlled space. The method includes partitioning a controlled space into one or more regions; evaluating motion within the controlled space; determining occupancy within the one or more regions. The method may also include adjusting conditions within the controlled space based on whether the controlled space, or a specific region thereof, is occupied. Corresponding devices and systems are also disclosed herein.

  • SYSTEMS, DEVICES, AND METHODS FOR MULTI-OCCUPANT TRACKING
    Publication number: 20140163703
    Abstract: A computer implemented method and system for multi-occupant motion tracking and monitoring may include partitioning out of a controlled space one or more interior regions, tracking one or more occupants within the controlled space by collecting a sequence of images of the controlled space, determining from the sequence of images one or more contiguous pixel groupings corresponding to non-persistent motion (referred to as blobs), and generating one or more bounding boxes that encompass each of the contiguous pixel groupings.

  • Systems and Methods for Commissioning a Sensor
    Publication number: 20130332114
    Abstract: A computer implement method for commissioning a sensor is described. The method includes monitoring for a commissioning event. Upon detection of the commissioning event, a switch is paired with a sensor. A doorway that is in a field of view of the sensor is identified. A boundary that separates a doorway area from a neighboring area that is in the field of view of the sensor is also identified.
