20130146586 | Water Heater Demand Side Management System - A system for shifting energy demand from on-peak time windows to off-peak time windows by using hot water heater load shifting, while providing the end user with the level of service (i.e., availability of hot water) according to the user's customary use described by service quality criteria. The shift is accomplished by a controller located at the end user establishment and in communication with a central control server. The controller monitors local water heater upper and/or lower temperature and controls upper and/or lower water heater heating elements in accordance with a demand shift process commanded by the central control server. The controller may determine usage and remaining capacity for reporting back to the central control server. A volumetric capacity and usage determination is disclosed. The control server may select water heaters according to use patterns and/or measured capacity. One embodiment is adapted for use with existing water heaters without disrupting safety features of the existing water heater. | 06-13-2013 |
20120119922 | System and Method for Monitoring, Controlling, and Displaying Utility Information - A system and method for monitoring, controlling, and displaying utility information is provided. A collar communicatively connected to the utility meter monitors power usage and provides usage data, power quality data, and other data to the utility and the customer. The system provides for pre-pay power, and the collar relay can automatically connect or disconnect power to a customer as required. The system provides intelligent remote control of utility meters via wireless or other communications means. A display unit communicatively coupled to the collar displays customer utility usage data. In one embodiment, the system allows reconnect after disconnect upon receiving a confirmation to restore power from a customer input device at the customer premises. | 05-17-2012 |
