  • Patent number: 11209372
    Abstract: Examples relate to a method, an apparatus and a computer program for detecting a presence of airborne particles. A reference measurement of an environment of a depth image sensor module is obtained. The reference measurement is based on a measurement of modulated light in a first time interval. The modulated light is reflected by features of the environment of the depth image sensor module. A subsequent measurement of modulated light is obtained in a second time interval. The presence of the airborne particles is detected based on the subsequent measurement of the modulated light, by using the reference measurement performed in the first time interval to disregard all or part of the features of the environment of the depth image sensor module. A signal indicative of one or more properties of the detected airborne particles is generated based on the detected presence of the airborne particles.

    Abstract: The present invention relates to an emergency notification system where indicators are mounted on or in a building in such a way that optical or thermal signals emitted from the indicators form a time-variant indication detectable outside the building of an emergency event taking place inside the building. Sensors detecting a predetermined sound are mounted inside the building and are each connected to a nearby indicator. When a sensor makes a detection, it sends event information to its associated indicator which will prompt the indicator to emit a first optical or thermal signal. Based on a signal from a timer connected to the indicator, a property of the first signal will change after a certain time has passed, thereby providing the time-variant indication.

  • Patent number: 10262513
    Abstract: A light emitting device includes several light emitting diode unit groups, a battery, a microprocessor, and a smoke detector is disclosed. When the light emitting diode unit groups receive power supplied from an external power supply, the external power supply charges the battery through the part of the plurality of light emitting diode unit groups, and the external power supply drives at least one of the plurality of light emitting diode unit groups. When the light emitting diode unit groups do not receive the power supplied from the external power supply, the battery discharges to drive the at least one of the plurality of light emitting diode unit groups. When the smoke detector detects that a smoke concentration in an environment exceeds a preset value, the microprocessor sends a flickering signal so that the at least one of the plurality of light emitting diode unit groups flickers.
