    摘要： A Wi-Fi mesh fire detection system and methods therefor are provided. The system can include a plurality of access points, where each access point in the plurality of access points is wirelessly connected to at least two other access points in the plurality of access points. For example, a first access point can be assigned as a primary parent device to a third access point, and a second access point can be assigned as a secondary parent device to the third access point. The third access point can transmit a message to the secondary parent device when the third access point fails to confirm that the primary parent device successfully received the message transmitted by the third access point.

    摘要： A method includes receiving, in a scanner, at least one radio-frequency (RF) signal from a sensor proximate to the scanner. The method also includes storing location information, corresponding to a location of the scanner, and signal strength information corresponding to the scanner. The method further includes calibrating location records according to the signal strength information and location information. There is also a system for calibrating location records. The system includes a plurality of sensors each configured to transmit an RF signal. The system also includes a scanner configured to receive at least one RF signal from a sensor proximate to the scanner, store location information corresponding to a location of the scanner, and store signal strength information corresponding to the scanner. The system further includes a location manager configured to receive the stored signal strength information and location information from the scanner and to calibrate location records according to the stored signal strength information and location information.

    摘要： A public address system installed in a building or other region being monitored can communicate with a regional fire detection system. Responsive to information received from the fire detection system as to developing dangerous conditions, a control unit for the public address system can adaptively create one or more evacuation routes for a region associated with a developing condition. One or more loud speakers in the region can be used to communicate a preferred evacuation route to individuals in the region. The route can be dynamically altered as the condition varies over time.

    摘要： A system for tracking persons in a structure, using a mobile unit for transmitting a distinctive beacon signal to a wireless array network of RF transceivers when the signal is within a predetermined distance of one or more RF transceivers, and transmitting the received RF beacon signal and a signal representative of itself to other RF transceivers through the array to a computer gateway. The computer determines the location of the mobile unit from the transmitted signals and displays the location.
