Patent ID: 7066919

Claim:
An alarm assembly for alerting a user of a fluid-receiving receptacle to an incremental fluid quantity in the fluid-receiving receptacle, the fluid-receiving receptacle comprising a flexible fluid-impermeable casing, fluid passage means, and first and second receptacle surfaces, the first and second receptacles surfaces being adjustably distant from one another, the adjustably distant first and second receptacle surfaces having a select alarm activation distance therebetween, the alarm assembly comprising: an alarm module and first and second magnetic field sources, the alarm module comprising select user alert means, magnetically-actuated first and second switches, and power source means, the alarm module and the first magnetic field source being attached to the first receptacle surface, the second magnetic field source being attached to the second receptacle surface, the first and second magnetic field sources actuating the first and second switches, the fluid passage means enabling a fluid quantity to increment intermediate the first and second receptacle surfaces, the incrementing fluid quantity having an incremental volume, the incremental volume increasing the distance intermediate the first and second receptacle surfaces, the second magnetic field source deactuating the second switch when the select alarm activation distance is adjustably met, the deactuated second switch electrically communicating the power source means with the select user alert means thus energizing the select user alert means, the energized select user alert means for alerting a user to the incremental fluid quantity in the fluid-receiving receptacle.
