315246, 315291
Abstract:
A system for programming control of ballast illumination includes receiving a power stage input current through a first ballast input, receiving a level switch control signal at a second ballast input, entering a ballast illumination program mode, adjusting said level switch control signal to select a ballast lamp illumination and saving a field-programmed ballast lamp illumination indication in a ballast memory as representative of said ballast lamp illumination.

Abstract:
A system for controlling ballast illumination includes providing power to a light ballast power stage, driving a ballast lamp to a pre-determined ballast lamp illumination in response to the power stage receiving power, and actuating a level switch to drive the ballast lamp from the pre-determined ballast lamp illumination to a first field-programmed ballast lamp illumination.

Abstract:
An energy monitoring and control system (10) for use with a conventional AC source (12) having a hot wire and a neutral wire (28). The energy monitoring and control system (10) includes a control station (14) and a number of controllable loads (20). The control station (14) is coupled in series with the hot wire of the AC source and is physically located between the AC source (12) and the loads (20). The individual loads are connected in parallel with each other and are coupled to the AC surce (12) and the control station (14). The control station (14) can communicate with the loads in various ways, a preferred scheme being a power-line communication method. Each of the loads is equipped with circuitry for receiving and executing commands sent by the control station (14). The control station (14) can receive information from the loads (20) by observing the AC supply current drawn by the loads (20).
