Power reduction method in an electronic counter
View Patent ↗A method for operating an electronic counter with reduced power consumption has been developed. The electronic counter is divided into multiple segments that are ordered according to their numerical value. As the counter is updated, it becomes necessary to propagate data between the segments. If the supply energy of the counter meets or exceeds a set limit, the data is propagated to the next highest segment. However, if the supply energy of the counter falls below the set limit, the data to be propagated is stored in a propagation carry counter.
1. A method for operating an electronic counter, comprising:
updating the electronic counter for a water meter where the electronic counter is divided into a plurality of segments that are configured according to numerical value;
propagating data between the segments when the supply energy of the electronic counter meets or exceeds a pre-determined value; and
storing the propagated data for later transmission to an end user in a two-bit binary propagation carry counter when the supply energy of the electronic counter does not meet the pre-determined value.
2. The method of claim 1 , where the two-bit binary propagation carry counter stores the propagated data until the supply energy of the electronic counter meets or exceeds the pre-determined value.
3. The method of claim 1 , where the electronic counter is divided into three segments.
4. The method of claim 1 , where the electronic counter is divided into an up counter with three segments and a down counter with three segments.
5. The method of claim 1 , where the plurality of segments comprise memory cells.
6. The method of claim 5 , where the memory cells are non-volatile memory cells.
7. The method of claim 6 , where non-volatile memory cells comprise FeRAM cells.
8. The method of claim 1 , where the water meter is a self-powered water meter.
9. The method of claim 8 , where the self-powered water meter is powered by a Wiegand Wire.
10. The method of claim 1 , where the propagation carry counter generates an error notification when the propagation carry counter's contents are full and the propagation carry counter receives additional propagated data.
