| 摘要 |
This invention relates to a building intruder defensive shield system to deter, delay and distract intruders from causing damage or harm upon entering and roaming buildings. The defensive shield system includes a cold water supply plumbed to an expansion tank capable of pressurizing the water with a zone valve and nozzle. A motion sensor, control relay, and a central processing unit communicate signals to and from each other and the zone valve to disperse a timed, forced spray of water, preferably containing dye or a chemical irritant, on the intruder. Manual or gunshot detection means are included to identify and locate the intruder. |

1. A building intruder defensive shield comprising a shield module, the shield module comprising a cold water supply line, an expansion tank, a zone valve, a motion sensor device, an intruder alert means, a nozzle, and a relay board with a control relay, the control relay is connected to a central processing computer via a hard wired or a wireless Local Area Network,
the central processing computer comprising a software application means for recognizing sensor alerts, sending activation signals to the zone valve to turn on and off the water sprayed from the valve, and software applications to be used by mobile devices/wireless computers for delivery of system information to law enforcement and building occupants, the cold water supply is plumbed to the expansion tank, zone valve and nozzle providing a flow of water to the expansion tank, the expansion tank comprising pressurized means to provide pressurized water to the zone valve, the zone valve is connected to the plumbed cold water supply, expansion tank and nozzle between the expansion tank and nozzle to regulate the flow of water from the expansion tank to the nozzle, the motion sensor device is located on a wall or ceiling of a building hallway or room to sense movement in that hallway or room or to receive a signal from the intruder alert means, the motion sensor device is connected to the control relay via a hard wired or a wireless Local Area Network to send an electronic signal to the control relay of movement near the motion sensor device or of receipt of the signal from the intruder alert means, the zone valve is further connected to the control relay via a hard wired or a wireless Local Area Network to receive electronic instructions to open or close, thereby allowing water to flow to the nozzle, whereby when an intruder is discovered in the building, the intruder's location would be identified by the intruder alert means which would send a signal to the central processing computer activating the shield module, the central processing computer receiving the location of the intruder through the intruder alert means and the motion sensor device sends a signal to the zone valve in the area of the intruder's location to open, thereby allowing a timed burst of cold water throughout that area. |
