Multi function electronic personal monitor and radio telemetry cell system

A multi function personal alert safety cell system having condition responsive sensor means and alarm means indicative of personal safety conditions including a small size portable casing, said casing having an internal watertight sealed cavity and a sound resonating cavity with surrounding walls including at least one sound port providing a passage from the interior to the exterior of said resonating cavity;

• a slidable sealed flat wall for dividing electric and electronic control;
• operating circuitry disposed in said chamber including a source of electric power, push button control and electronic circuitry controlled by said operating circuitry;
• said sealed flat wall having a thin flat sound generating piezoelectric transducer device electrically connected to said circuitry means;
• a motion detector for generating a voltage output characteristic of which changes responsive to motion of said casing;
• and said operating circuitry further including a tone oscillator connected between said motion detector and said piezoelectric sound generating transducer and responsive to the output of said motion detector and said piezoelectric sound generating transducer and responsive to the output of said motion detector to cause a specific high intensity sweeping alarm signal to be emitted when the operating circuitry is turned on and in the event that the casing is motionless, wherein the improvement comprising:
• a transceiver for transmitting and receiving data unique to said cell system in said casing at multiple frequencies and at multiple power levels;
• and
• said transmitted and received power levels being defined as P1, P2, P3, P4, P5, through Pn, said each power level P1, P2, P3, P4, P5 through Pn being transmitted and received with a digital encoded number uniquely assigned to said particular power level for defining a power level ID, said power level ID varying in field strength for defining a distance at which said transceiver detects said transmitted and received signal which is indicative of the distance said transceiver is from another separate and distinct transceiver.

A plurality of multi function personal alert safety cell systems, comprising:

• a plurality of transceivers, each said transceiver for transmitting and receiving at several different radiated power levels, defined as P1, P2, P3, P4, P5, through Pn, that vary in signal strength from 1 microwatt through 1 watt, each said power level P1, P2, P3, P4, P5, through Pn being transmitted and received with encoded data and a personal ID uniquely assigned to each of said plurality of transceivers;
• said plurality of unique transceivers transmitting and receiving data being contained within a time frame and having digital instructions and coded format sectors, said sectors being identified through a sector “A”;
• and
• said power level ID varying in field strength for defining a distance at which one of said transceivers detects said transmitted and received signal from another of said plurality of transceivers and said signal being indicative of the distance one of said transceiver is from another of said transceivers.
