Принадлежит:

An adaptive method and system for monitoring a shipping container for an environmental anomaly uses sensor-based ID nodes within the container and a command node. Sensors on each ID node generate sensor data about an environmental condition proximate the ID node as disposed within the container. Each ID node periodically broadcasts the sensor data. The command node monitors a first group of sensor data from the ID nodes over a first time period to detect an initial environmental threshold condition related to the container, then monitors a subsequent group of sensor data over a second time period under a modified monitoring parameter to detect a secondary environmental threshold condition related to the container as the anomaly. In response to detecting the secondary condition, the command node generates an alert notification and transmits the alert notification to an external transceiver to initiate a mediation response related to the anomaly. 124-.

An apparatus for providing an autonomous fire extinguishing system including a tank filled with an extinguishing agent with a targeting system with independently mounted targeting servos and targeting gimbal to position an emitter and an infra-red camera. A microcontroller provides control signals to the targeting servos and an actuation valve. One or more heat sensors, smoke detectors, humidity sensors, and/or carbon monoxide detectors are electrically connected to the microcontroller; and the microcontroller continuously reads in the sensor data till appropriate conditions indicating a potential fire are detected; these appropriate can be based on temperature, rate of temperate increase, smoke levels, humidity, and/or carbon monoxide levels. Once the appropriate conditions are detecting, the microcontroller commands the targeting gimbal to position the infra-red camera to a number of calculated positions, taking infra-red pictures covering the environment requiring protection. Based on the infra-red data from scanning, an elevated temperature location is determined. If the infra-red data and other sensor data confirm a fire, the emitter releases fire suppressant onto fire. Once the infra-red data and other sensor data confirm the fire is extinguished, the apparatus stops releasing suppressant and resumes monitoring the environment. 1.

Systems and methods for modular dwelling units that may be combined into a modular building. The modular dwelling units may be fluidly isolated from each other by a sealing system that prevents fluids from leaking into adjacent modular dwelling units, and a subfloor system that is tilted to drain fluids towards a conduit that leads away from the modular building. The modular dwelling units may include one or more sensors that generate signals based upon conditions within the modular dwelling unit and/or based on occupants of the modular dwelling unit. The modular dwelling units may include one or more processor-based devices that may generate an alarm and/or control one or more actuators or valves in response to the signals received from the sensors. 1. A modular building , comprising:a plurality of modular dwelling units, each of the modular dwelling units have a respective floor, a respective ceiling, and at least one respective perimeter wall, the respective floor, respective ceiling and at least one respective perimeter wall delimiting a respective interior of the modular dwelling unit from a respective exterior of the modular dwelling unit, the modular dwelling units physically coupled to a number of nearest neighboring ones of the modular dwelling units via at least one coupler, each of the modular dwelling units have a respective set of sensors to monitor a number of physical characteristics of the modular dwelling unit and a number of physical characteristics of any inhabitants of the modular dwelling units, and a respective set of actuators operable to control respective mechanisms of the respective the modular dwelling units; and 'monitor each sensor of a respective set of sensors for each of a plurality of modular dwelling units, each of the modular dwelling units have a respective floor, a respective ceiling, and at least one respective perimeter wall, the respective floor, respective ceiling and at least one respective perimeter wall delimiting a ...
