  • Patent number: 11860043
    Abstract: In an indoor environment on fire, automatic deployment of sensors disposed on, beneath or over the floor to look upward the ceiling to observe a body of smoke and flame risen near the ceiling allows important information regarding states and dynamics of the body of smoke and flame to be gathered at an early stage of fire (e.g. before arrival of firefighters). By distributing the sensors over the indoor environment, the states and dynamics of the body of smoke and flame are monitored holistically (i.e. as a whole) even at the early stage of fire. Such information is useful to predict development of the fire. In one implementation, a sensor is held in an infrastructure sensor holder mounted on the ceiling during normal time. Upon detecting occurrence of fire, the sensor drops from the holder to land on the floor and orients a sensing direction vertically upward to perform monitoring.

  • Publication number: 20230033404
    Abstract: A method for supporting positioning of a vehicle using a satellite positioning system is disclosed. The method includes generating, in real-time, a sliding window map (SWM) based on 3D point clouds from a 3D LiDAR sensor and an attitude and heading reference system (AHRS), wherein the SWM provides an environment description for detecting and correcting a non-line-of-sight (NLOS) reception; accumulating the 3D point clouds from previous frames into the SWM for enhancing a field of view (FOV) of the 3D LiDAR sensor; receiving global navigation satellite system (GNSS) measurements from satellites, by a GNSS receiver; detecting NLOS reception from the GNSS measurements using the SWM; correcting the NLOS reception by NLOS remodeling when a reflection point is not found in the SWM; and estimating a GNSS positioning by a least-squares algorithm. It is the objective to provide a method that mitigates NLOS caused by both static buildings and dynamic objects.
