In accordance with various aspects of the present disclosure, methods and systems for fire detection are disclosed. In some embodiments, a method for fire detection includes: acquiring data related to a monitored area, wherein the data comprises image data related to the monitored area; determining, based on the acquired data, whether a first mode or a second mode is to be executed for fire detection, wherein the first mode comprises a first smoke detection, and the second mode comprises a first flame detection; and executing, by a hardware processor, at least one of the first mode or the second mode based on a result of the determination.

A gas leakage treatment method includes detecting a target gas concentration of a target gas in an environment at a corresponding position of a gas delivery pipeline in a process of moving along the gas delivery pipeline. The method further includes, if the target gas concentration is greater than a preset concentration threshold, determining that gas leakage occurs and performing a gas leakage treatment operation.

A heat source detection device is a heat source detection device that detects a heat source on the earth using observation data of a radiometer provided in a geostationary satellite and includes: a calculation unit that calculates a heat source proportion value indicating a proportion of a wavelength distribution due to the heat source included in the observation data to the observation data by curve fitting using Planck's law; and a determination unit that determines presence or absence of the heat source according to the heat source proportion value calculated by the calculation unit.

Embodiments of the present invention are related to an automated structure and curtilage protection system including a mechanical system hub with at least one of a control center, a pump, a pressure tank, a plurality of controllable valves, and a chemical injector assembly. The system includes a piped network, a plurality of spray nozzles and a remote user control portal. The remote user control portal is structured to calculate a hazard distance by averaging a plurality of known data positioning points of a hazard relative to a structure, categorize the calculated hazard distance into a categorized threat level within a hierarchy of preprogrammed threat levels and actuate the mechanical system hub based on an instruction set corresponding to the categorized threat level within the hierarchy of preprogrammed threat levels.

The present disclosure discloses a device for detecting and alerting of a fire at the vicinity thereof. The device is deployed in an area at the outdoors, e.g. a forest, that is desired to be monitored. The device has two main parts, a first part that is intended to remain relatively cold and therefore is thermally isolated from the environment. The first part can be isolated by being inserted into a static object in the desired area, e.g. a trunk of a tree, or a rock, or, in some embodiments, can be surrounded by a thermal-isolating material. The first part is thermally connected to a first end of a thermoelectric generator (TEG) unit and a second part of the device, a hot part, is thermally connected to a second end of the TEG unit. The second part is intended to be thermally exposed to the ambient environment such that in case of a fire in the vicinity of the device, the second part is heated to high temperatures while the first part remains relatively cold since it is thermally isolated. Therefore, the second part causes the second end of the TEG unit to heat to high temperatures while the first end of the TEG unit remains relatively cold since it is thermally connected to the thermally-isolated first part that may be considered to function as a heat sink. The temperature difference between the two ends of the TEG unit generates an electrical energy, e.g. a voltage difference that is supplied to an alerting unit in the device. The alerting unit is inactive as long as there is no generated electrical energy by the TEG unit and become active only when the temperature difference reaches a certain value. Upon being activated by the electrical energy of the TEG unit, the alerting unit is configured to transmit an alerting signal indicative of the location of the fire. The alerting signal is received by a receiving station and triggers operation of fire fighters for extinguishing the fire quickly.

A portable weather station, including an lower body portion; an upper body portion disposed on the lower body portion in a spaced apart relationship thereby forming an open channel between the upper body portion and the lower body portion; and a plurality of weather condition sensors wherein a first set of one or more of the plurality of weather condition sensors is mounted on the upper body portion of the portable weather station and a second set of one or more of the plurality of weather condition sensors is mounted on the lower body portion of the portable weather station.

Embodiments of the present invention relate to, in general, a fire detection device and notification system configured for generating alerts based on detected environmental conditions (e.g., temperature, humidity, presence of flame or smoke or combustion gas). In some embodiments, the fire detection device employs various sensor devices (e.g., temperature, humidity, flame, smoke, gas, and the like) to collect environmental data and determine whether the detected environmental conditions indicate the presence of or the increased possibility of a fire. In some embodiments, the invention further comprises a notification system for automatically generating and transmitting alerts to one or more computing devices (e.g., responder dispatch systems) based on the detection of hazardous conditions.

An outdoors fire alerting device, including a first part and a second part spaced apart from one another by a thermoelectric generator unit, the first part being shaped for insertion into a static object and the second, exposed part intended for being exposed to the ambient environment while the first part is retained within the static object; the first part, the second part and the thermoelectric generator unit being integrally coupled to one another, the thermoelectric generator unit being configured to generate electrical energy in response to a temperature difference between the first part and the second part, an alerting unit electrically coupled to the thermoelectric generator unit and configured to transmit a signal indicative of fire alert when the temperature difference between the first and the second part reaches a predefined value, where the first part has a generally cylindrical shape and is elongated along a first axis, where the first part is axial symmetric about the first axis.

A device for characterizing a fire comprises at least one stereovision system and at least one processing unit. The at least one stereovision system comprises a first and a second image capture unit. The at least one processing unit is configured to determine at least one geometric characteristic of the fire. The processing unit is also configured to determine a radiative flux of this fire on the basis of a calibrated linear relationship established between a radiative flux of a reference fire as a function of at least one of the geometric characteristics of the fire and of at least one fire category in order to be able to determine zones exposed to a radiative flux that exceeds a reference threshold. The present disclosure also relates to a method for determining radiative fluxes that implements such a fire characterizing device.
