Abstract
Abstract To allow a tester to test whether a switching arrangement near a customer's premises has connected and reconnected loads according to load management command signals from a central utility transmitter, a switch autogenically transmits, over and over, status signals indicating the status of the contacts in the switching arrangement.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
130 words
For controlling a plurality of electrical loads, an electrical load management system comprising: utility control means for transmitting load management signals to control the loads; load management switch means responsive to the control means and associated with each of the loads for responding to the load management signals from said utility control means and for regulation operation of the loads; portable test means for receiving data and visually displaying the data; and said load management switch means having storage means for storing the data concerning the load management signals and having transmitting means coupled to said storage means for autogenically transmitting the stored data so that when said portable test means is within range of the transmitting means, said portable test means can receive data transmitted by said transmitting means.
Claim 2
Dependent Claim
130 words
For controlling a plurality of electrical loads, an electrical load management system comprising: utility control means for transmitting load management signals to control the loads; load management switch means responsive to the control means and associated with each of the loads for responding to the load management signals from said utility control means and for regulation operation of the loads; portable test means for receiving data and visually displaying the data; and said load management switch means having storage means for storing the data concerning the load management signals and having transmitting means coupled to said storage means for autogenically transmitting the stored data so that when said portable test means is within range of the transmitting means, said portable test means can receive data transmitted by said transmitting means.
Claim 3
Dependent Claim
15 words
A system as in claim 1, wherein said transmitting means transmits the stored data repeatedly.
Claim 4
Dependent Claim
20 words
A system as in claim 1, wherein said transmitting means transmits the stored data repeatedly on a continuing endless basis.
Claim 5
Dependent Claim
21 words
A system as in claim 1, wherein said transmitting means transmits the stored data repeatedly in bursts with delays between repetitions.
Claim 6
Dependent Claim
23 words
A system as in claim 1, wherein said transmitting means transmits the stored data repeatedly with substantially no delay between the repeated data.
Claim 7
Dependent Claim
85 words
For controlling a plurality of electrical loads in response to load management signals from a control center, an electrical load management switch comprising: load management control means associated with each of the loads for responding to the load management signals from said control center and for regulating operation of the loads; storage means for storing the data concerning the load management signals; and transmitting means for autogenically and continuously transmitting the stored data so that the transmitted data can be received by a portable tester.
Claim 8
Dependent Claim
85 words
For controlling a plurality of electrical loads in response to load management signals from a control center, an electrical load management switch comprising: load management control means associated with each of the loads for responding to the load management signals from said control center and for regulating operation of the loads; storage means for storing the data concerning the load management signals; and transmitting means for autogenically and continuously transmitting the stored data so that the transmitted data can be received by a portable tester.
Claim 9
Dependent Claim
15 words
A switch as in claim 6, wherein said transmitting means transmits the stored data repeatedly.
Claim 10
Dependent Claim
23 words
A switch as in claim 6, wherein said transmitting means transmits the stored data continuously and repeatedly in bursts with delays between repetitions.
Claim 11
Dependent Claim
25 words
A switch as in claim 6, wherein said transmitting means transmits the stored data continuously and repeatedly with substantially no delay between the repeated data.
