Unauthorized utility use monitor apparatus and method
First Claim
1. A system for monitoring unauthorized use of a utility at each of a plurality of consumer'"'"'s premises, the system including:
- a consumer meter at each consumer'"'"'s premises, the consumer meter being connected to measure use of the utility;
a local processor, including at least one memory register, at each consumer'"'"'s premises operatively coupled to the consumer meter and for storing readings from the corresponding consumer meter, each consumer meter and local processor comprising a subscriber unit;
a communications network;
first communication means operatively coupled to the local processor and to the communications network, and disposed at each consumer'"'"'s premises, for facilitating communication over the network with the subscriber unit;
a central processor at a central location including storage means for storing information concerning each consumer'"'"'s premises;
second communication means operatively coupled to the communications network and the central processor, and disposed at the central location, for enabling information to be transmitted selectively between the central processor and each local processor via the communication network and the respective first communication means;
information input means operatively coupled to the central processor for generating an authorization signal for each consumer'"'"'s premises, the storage means storing an authorization signal for each consumer'"'"'s premises indicative of whether use of the utility is authorized or is not authorized;
wherein the central processor periodically polls each local processor to detect consumption of the utility, verifies whether or not consumption is authorized by checking the corresponding authorization signal in the storage means, and generates an unauthorized use signal when unauthorized use is detected at a corresponding consumer'"'"'s premises.

Abstract
A system for monitoring use of a utility at a consumer'"'"'s premises is disclosed. The system may include monitoring apparatus to detect use of the utility, a first register to store an indicator signal indicating whether or not use of the utility at the consumer'"'"'s premises is authorized, and an unauthorized use signal generator, responsive to the monitoring apparatus output and the contents of the register, to generate an unauthorized use signal when the monitoring apparatus output indicates use of the utility and the first register contains an indicator signal indicating that use is not authorized.

4. A system for monitoring unauthorized use of a utility at each of a plurality of subscriber'"'"'s premises, the system comprising:
-
a consumer meter at each subscriber'"'"'s premises, the consumer meter being connected to measure use of the utility; a local processor, including at least one memory register, at each subscriber'"'"'s premises operatively coupled to the corresponding consumer meter, for storing readings from the corresponding consumer meter, each consumer meter and local processor comprising a subscriber unit, the local processor having an authorization signal register for storing an authorization signal; a communication network; first communication means operatively coupled to the local processor and to the communications network, and disposed at each subscriber'"'"'s premises, for facilitating communication over the network with the subscriber unit; a central processor at a central location; second communication means disposed at the central location and operatively coupled to the central processor and to the communication network, for enabling information to be transmitted selectively between the central processor and each local processor via the communication network and the respective first communication means; information input means operatively coupled to the central processor, for generating an authorization signal for each subscriber'"'"'s premises, the central processor transmitting the authorization signal to the corresponding local processor which stores the authorization signal in the corresponding authorization signal register; wherein each local processor verifies whether or not consumption of the utility is authorized at the corresponding subscriber'"'"'s premises in accordance with the signal in the authorization signal register and transmits an unauthorized use signal to the central processor when use which is not authorized is detected at the corresponding subscriber'"'"'s premises. - View Dependent Claims (5, 6)
