A combination recessed light with a smoke sensor and a carbon monoxide detector to detect for both smoke and carbon monoxide gas in a room. The recessed light can be a wafer style recessed light with an LED light source with a cover plate forming a smoke collection chamber with a smoke detecting sensor located within. A smoke collecting area is located below the LED light source and is connected to the smoke collection chamber thru one or more holes. A box mounted to a wall of the room can have a carbon monoxide sensor, a battery, and speaker, and a test button to sound an alarm for both the smoke sensor and the carbon monoxide sensor. The test button is used to test both the smoke detector and the CO sensor. An array of recessed lights is mounted to a ceiling and a power convertor device converts 110-volt power to 20-volt power that is supplied to each of then LED light sources.

The present invention relates to a system for testing the availability of a detector for detecting smoke. More specifically, the present invention relates to a detector with a testing unit arranged to detect whether the detector has been covered, such that it is unable to perform its function as a smoke detector.

A method is provided for diagnostic checking of a variable memory 14 in a safety critical system in order to detect variable memory failures; wherein the safety critical system comprises a central processing unit (CPU) with an operating system, an internal volatile memory 12 and an external volatile memory 14 including the variable memory 14; and the CPU can access a plurality of address spaces including one or more address spaces of the external volatile memory 14 that are utilised by the operating system and/or by a safety critical application of the safety critical system during normal use of the safety critical system.

Some embodiments are directed to a system that includes multiple fire sensors and equipment, and mobile devices of the users of the system. These fire sensors and equipment are configured in a network so as to allow communication with a processor. A processor in the system interrogates the status of the fire sensors and fire safety elements on a continuous basis. Upon a change in system status, the processor interprets the change and classifies according to operation state or probability of a fire or other imminent threat. The data, processing and storage provide the means by which occupants and potential occupants can better navigate a building during the occurrence of a fire. The system enables communication between users of the system through their mobile devices used and communication between devices that may be present in the

An appliance hub for use in an upper portion of an enclosure can include a substrate configured to be positioned in an upper portion of an enclosure. The appliance hub can include a climate control apparatus mounted on the substrate and the climate control apparatus can be configured to regulate a temperature within the enclosure. The appliance hub can include one or more lighting elements configured to provide light within the enclosure, a plurality of fluid lines connected to the substrate and configured to provide fluid service and return to the climate control apparatus, and/or a plurality of electrical connections connected to the substrate and configured to provide electrical power and/or data to at least one of the climate control apparatus and the one or more lighting elements.

A three-dimensional (3D) visual monitoring method for a building, a 3D visual monitoring system for a building, and a storage medium. The 3D visual monitoring method for a building includes acquiring a building information modeling (BIM) model and sensor data of a building, the sensor data being collected by a sensor arranged in a building area; integrating the sensor data into the BIM model; and transmitting the integrated BIM model to a display terminal, for use in a monitoring operation of the building.

System, methods, and other embodiments described herein relate to improving the safety of a vehicle in relation to occurrences of smoke and fire. In one embodiment, a method includes acquiring, from a radar of a subject vehicle, radar data about a passenger cabin of the subject vehicle. The method includes determining a current state of the passenger cabin according to the radar data. The method includes, responsive to identifying that the current state indicates smoke is present within the passenger cabin, controlling the subject vehicle to generate a response to the smoke.
