    摘要： 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.

    摘要： Smoke detectors and smoke alarms are provided which have one or more light shields configured to block or minimize the transmission of ambient light to their light receivers. Light shield configurations for facilitating such functionality are provided as well. The shield/s include a material which attenuates a majority amount of light within a particular range of light that a light source of the smoke detector may be configured to only emit and/or the range of light the light receiver may configured to only convert to photocurrent. In some cases, the shield/s surrounds the light source and/or the light receiver arranged external to an interior chamber of the smoke detector. In some cases, the shield/s may at least partially span a connection side of an external housing of the smoke detector. Alternatively, the shield may be arranged in a space between the interior chamber and the connection side of the housing.

    摘要： A smoke alarm has a housing with a heating device for heating walls of the housing to a temperature above the dew point. The heating device has at least one heating light emitting diode (LED). The heating LED has an opening angle for the emission of light, which opening angle leads to an irradiated area of the housing.

    摘要： An air filtration for detecting hazardous particles includes a housing having an air flow pathway extending therethrough. The housing is configured to receive air flow from an inlet of the housing and to expel air flow from an outlet of the housing. A pair of electrodes are positioned within the air flow pathway. A sensor system is operatively connected to the pair of electrodes to measure electrical current flowing therebetween. A processor is operatively connected to the sensor system to compare the measured electrical current with a stored baseline current. An alarm is operatively connected to the processor. The processor activates the alarm when the measured electrical current is different than the stored baseline current.

    摘要： This patent specification relates to a wall switch that comprises a docking station and a user-removable wall-switch head unit. In some embodiments, the docking station is configured to receive the user-removable wall-switch head unit, and configured to be permanently connected to a wall and coupled to high-power voltage wires. In some embodiments, the user-removable wall-switch head unit is configured to be user-insertable into said docking station and user-removable therefrom such that the user is not exposed to high-voltage connections when inserting or removing. In some embodiments, the wall switch controller further comprises inputs and outputs and circuitry for switchably controlling household line current power to a household electrical fixture. In some embodiments, the wall switch controller further comprises an occupancy sensor, a temperature sensor, or a processor.

    摘要： Various methods, systems, and devices for identifying a condition of a battery-powered device are presented. For example, a device may include a smoke detection sensor that detect smokes and, in response to detecting smoke, generate a smoke detection signal. The device may include test circuitry that tests an aspect of the battery-powered device. The device may include an audio output device that outputs a sound in response to the test circuitry determining a particular condition is present. The device may include a proximity detector that monitors for a wave movement of an object within a distance of the battery-powered device and generates a proximity detection signal when the proximity detector detects the wave movement performed by the object within the distance of the smoke detector device.

    摘要： A smoke detection sensor ion chamber has a leakage current that is dependent upon the permittivity of the ionized gas (air) in the chamber. Smoke from typical fires is mainly composed of unburned carbon that has diffused in the surrounding air and rises with the heat of the fire. The permittivity of the carbon particles is about 10 to 15 times the permittivity of clean air. The addition of the carbon particles into the air in the ion chamber changes the permittivity thereof that is large enough to detect by measuring a change in the leakage current of the ion chamber.
