A robot in a location interacts with a user. The robot includes a camera, an image recognition processor, a microphone and a loudspeaker, a voice assistant, and a wireless transceiver. The robot moves around and creates a model of the location, and recognizes changes. It recognizes objects of interest, beings, and situations. The robot monitors the user and recognizes body language and gesture commands, as well as voice commands. The robot communicates with the user, the TV, and other devices. It may include environment sensors and health status sensors. It acts as a user companion by answering queries, executing commands, and issuing reminders. It may monitor to determine if the user is well. The robot may monitor objects of interest, their placement and their status. When necessary, it communicates with the user.

A fire door system is disclosed herein. The fire door system comprises a door and a door control unit coupled to the door. A plurality of sensors is configured on the door or adjacent the door. A controller is coupled to the door control unit and the plurality of sensors. The controller facilitates activation of the motorized door unit for maintaining the door in a closed position subsequent to sensing of a surrounding temperature by the plurality of sensors, wherein the surrounding temperature is greater than a threshold temperature.

A heat sensor includes a base and a heat sensor body. The base is to be mounted onto a mounting surface of a building. The heat sensor body has a bottomed cylindrical shape and is to be attached to the base. The heat sensor body includes an opening, a board, a heat detection unit, and at least one wall member. The at least one wall member controls flow of a gas to cause the gas that passed through the opening to flow toward the heat detection unit. The at least one wall member separates the flow of the gas that has entered the heat sensor body from an external space through the opening into a plurality of gas flows and directs one of the plurality of gas flows, which has been separated to flow beside an inner surface of the heat sensor body, toward the heat detection unit.
