First Claim
Patent Images
1. A portable pressurized equipment assembly comprising:
- a pressurized tank assembly, including;
a tank defining a volume, and a gauge in communication with the volume defined by the tank which signals a pressure of contents held within the volume defined by the tank;
a docking station mounted in the vicinity of and in communication with the tank; and
a signaling control circuit disposed in communication with the pressurized tank assembly and the docking station and, upon detection of a predetermined condition among a set of predetermined conditions comprising at least one predetermined internal condition and at least one predetermined external condition, having an output carrying a signal indicative of the predetermined condition, the signaling control circuit further comprising cooperative male and female electrical/communication connection elements defined by the pressurized tank assembly and the docking station, the at least one predetermined internal condition comprising a low pressure condition within the pressurized tank assembly, and the signaling control circuit further comprising a detector of the predetermined internal condition, the detector of the predetermined internal condition being adapted, upon detection of the predetermined internal condition, to actuate issue of the output corresponding to the predetermined internal condition, the at least one predetermined external condition comprising an input from an electronic circuit external of the pressurized tank assembly, and the signaling control circuit further comprising a detector of the predetermined external condition, the detector of the predetermined external condition being adapted, upon detection of the predetermined external condition, to actuate issue of the output corresponding to the predetermined external condition, and the signaling control circuit further adapted to issue the output to a remote station and to receive the input from a remote station.

Abstract
A portable fire extinguisher assembly includes a fire extinguisher with a tank containing fire extinguishing material, a valve for metering release of the fire extinguishing material, and a gauge displaying pressure within the tank, and a docking station in communication with the fire extinguisher. An electronic circuit in communication with the fire extinguisher and the docking station issues a signal upon detection of predetermined conditions, including at least one predetermined intenal condition and at least one predetermined external condition. The fire extinguisher electronic circuit includes cooperative male and female electrical/communication connection elements defined by the fire extinguisher and docking station.
