Abstract: Addressable amplified speakers assembly, and method for addressing the same, suitable for any permanent or temporary public address paging application. Amplified speakers assembly may incorporate VHF and UHF radios to provide wireless, one-way paging from a few feet to many miles away. These speakers can be added to any existing radio system with minimal effort or cost. The need for routing signal cable is eliminated, greatly reducing installation costs. Each speaker can be programmed for individual, group, or all-page access via DTMF or 2-Tone coding (up to 8 different addresses). The volume of each speaker can also be controlled remotely.
Abstract: An electronic circuit designed to reduce energy consumption by toggling between a plurality of conventional or electronic fluorescent lighting ballasts within a given fixture, and where said toggle circuit shall increase or decrease fixture light output levels according to immediate requirements. Toggle circuit may be remotely controlled from conventional Mains wall switch or other such means. Initial applications of Mains power automatically provides the minimum of light levels. Additional momentary interruptions to Mains power provides varied and/or additional lighting levels.
