Pager system with use monitoring
First Claim
1. An electronic communication monitoring system comprising:
- a plurality of portable receivers each having an energy source, each receiver including a communication system to communicate specific information to a user of the receiver, the communication system configured to communicate specific information upon receipt of a specific code by the receiver;
a control unit coupled to a transmitter to signal the receiver by transmitting through the transmitter the specific code for the receiver;
a first memory for storing information of each receiver;
a second memory for storing reference data of each receiver;
a clock having a time data output; and
a central unit directly coupled to the control unit, to the first memory, to the second memory, and to the clock, the central unit including a comparison device for comparing the information of the receiver from the first memory to the reference data of each receiver from the second memory and the time data output to detect an undesired situation relating to the receiver and to communicate the undesired situation to the control unit wherein the control unit will cause the transmitter to transmit the specific code of the receiver corresponding to the undesired situation.

Abstract
A pager system includes a transmitter with a control unit for selectively transmitting radio signals having specific pager codes, and a plurality of portable pager receivers each having its own electrical energy source and adapted to respond to a specific pager code. The pager system further includes a central unit coupled to the control unit. The central unit includes a comparing unit and is coupled to a first memory for storing information relating to the individual pager receivers, a second memory for storing reference data, a clock, and a presentation unit. The comparing unit compares the contents of the first and second memories for a specific receiver and clock data, and signals the transmitter when a code signal is needed. The presentation unit generates a warning signal in response to a code signal received from the transmitter.

15. An electronic communication monitoring system comprising:
-
a plurality of receivers, each receiver being connected to a battery and including a communication system to communicate information about the battery to a user of the receiver upon receipt of a specific code; a control unit coupled to a transmitter to signal each receiver, the control unit signaling each receiver by transmitting through the transmitter a specific code for the receiver; and a central unit directly coupled to the control unit, to a clock, to a first memory and to a second memory, the first memory and second memory receiving information relating to each battery, the central unit including a comparison device for comparing the contents of the first memory to the contents of the second memory and the clock output to detect an undesired situation and communicating the undesired situation to the control unit, wherein the control unit will signal a specific code to a receiver corresponding to the undesired situation which will activate the communication system to communicate information about the battery corresponding to the specific code received. - View Dependent Claims (16, 17)
