The present disclosure provides a smoke detecting circuit and a display panel using the smoke detecting circuit. The circuit comprises a smoke sensor, a smoke detecting module, and a first switch module. When the circuit is triggered on fire or smoking because of a short circuit, the smoke sensor is determining to detect smoke signal, the smoke detecting module is determining to export controlling signal immediately to control the disconnection of the first switch module, cutting off the power source of the load, protecting the load immediately while the accident happens. A load can be a display panel. A smoke detecting circuit is used for detecting the smoke signal of the display panel, without any additional external multi-function card, which reduces the installation space of the display panel with an easier arrangement of flat cables, determining to protect the display panel right away from the accidents.

An improved smoke detection enclosure for recessed installment is disclosed herein. A smoke detector for recessed installment can comprise a housing, a printed circuit board (PCB), a bottom cover, and a plurality of clips. The housing can be capable of being installed within a surface. The printed circuit board (PCB) can comprise one or more smoke detection systems. The PCB can be mounted within the housing such that upon installation into a surface, the PCB is approximately at the surface. The bottom cover can extend beyond edges of the housing to form a surface lip. The surface lip can be capable of interacting with a first side of the surface. The bottom cover can comprise one or more air vents, each of the one or more air vents can be placed directly underneath of each of the one or more smoke detection systems.

A system and method for detecting smoke using a photoelectric sensor is disclosed herein. The smoke detector can comprise a photoelectric smoke detection system, a smoke detector memory, and a microprocessor. The photoelectric smoke detection system can comprise a low-frequency light source, a high-frequency light source, and a light sensor. The smoke detector memory can comprise a smoke detector application, a plurality of low-frequency smoke signatures, and a plurality of high-frequency smoke signatures. Each of the low-frequency smoke signatures can relate to how a low-frequency light interacts with one of a plurality of particulates. Each of the high-frequency smoke signatures can relate to how a high-frequency light interacts with one of the plurality of particulates. Each of the particulates can be indicative or non-indicative of a fire.

This application is directed to a home monitoring and control system including a doorbell installed at a door of a home. The doorbell has a button configured to, upon being touched, depressed or activated, wirelessly initiate a first communication to indicate presence of a person at the door. The doorbell also has a camera configured to capture video data within a field of view, and a processor configured to cause a communication component to enable the first communication and wirelessly stream via a remote server the video data captured by the camera to a monitoring device associated with an occupant of the home. A rechargeable battery is coupled to a housing wire and configured to be charged via the housing wire, and the doorbell is configured to charge and discharge the rechargeable battery based on power usage of the doorbell.

The improved smoke detector is an alarm. The improved smoke detector monitors the atmosphere for both smoke and an increase in temperature consistent with the presence of a combustion reaction such as a fire. The improved smoke detector communicates an alarm message to an appropriate authority over a commercially provided and publicly available cellular wireless network. The alarm message informs the appropriate authority of the combustion reaction. The improved smoke detector comprises a housing and a control circuit. The housing contains the control circuit. The control circuit monitors the atmosphere for both smoke and an increase in temperature. The control circuit transmits the alarm message to the appropriate authority.

Embers created by fires, particularly fires in environments such as grassland, bushland, and forests, can lead to the loss of property and animal and human lives. In addition to the loss of property and lives, fires caused by embers lead to an increase in greenhouse gasses, an increase in the risk associated with an ember attack and/or a fire, and a reduced ability to effectively fight an ember attack and/or a fire. The concept bush/wildfire should be understood to include forest fires, grassland fires, and the like. The present disclosure relates to an ember detector device, a bush/wild fire detection and threat management system, and methods of reducing greenhouse gasses, reducing the risk associated with an ember attack and/or a fire, and enhancing an ability to effectively fight an ember attack and/or a fire.

An automatic fire suppression system for use in extinguishing residential fires or engine compartment fires in a vehicle. The automatic fire suppression system in mountable on a ceiling or under a hood of the vehicle or above the vehicle's engine if located elsewhere. The automatic fire suppression system retains an extinguishing agent in an extinguishing agent reservoir. A detection component for detecting heat or smoke triggers the release of the extinguishing agent according to a preset heat level or smoke condition. Once released, the extinguishing agent is dispensed onto the fire by through a plurality of orifices in a distribution component to effectively suppress the fire.

An electronic device has a DC/DC boost converter that includes a power NFET. The power NFET is coupled between a first pin, which can be coupled to a battery through an inductor, and a second pin that can be coupled to a ground plane. A switch-node is coupled to a third pin, which can be coupled to a diode to provide a boosted output voltage. A gate driver can receive a FET-on signal and drive a gate of the power NFET. A digital logic circuit provides the FET-on signal and includes an Ipeak gear-shifting circuit that dynamically changes the value of a peak inductor current responsive to one or more determinations that are related to one of the boosted output voltage and a switching frequency of the DC/DC boost converter.
