Abstract: A line output converter (LOC) combined with a microprocessor to sense LOC output signal strength and respond to usefully high levels by generating a trigger to turn on an amplifier that is receiving the LOC output signal. A short, first predetermined time is programmed into the microcontroller as a minimum time to sense high signal levels before activating the amplifier, in order to suppress transient signals. A longer, second predetermined time is programmed into the microcontroller as a minimum time to sense low signal levels before deactivating the amplifier. The predetermined boundary between a high and a low signal level is also programmed into the microcontroller and, as with the predetermined times, is established responsive to the characteristics of the particular LOC involved. In an embodiment, the LOC is a compact adjustable LOC located on the same PCB as the microcontroller.

Abstract: A distribution block element having opposed input and output couplings and integral complimentary mechanical connectors to additional adjacent distribution block elements, allowing expansion by addition of distribution block elements. Fuse couplings are spaced apart for a mini2 blade fuse and have a length that is are spaced apart for a maxi APX heavy duty fuse and for direct conductors. When two elements are connected adjacently, the spacing between the adjacent crossbar couplings is the same as the spacing between the opposed input and output fuse couplings in each element. Thus, identical crossbar conductors can be used both for electrically connecting opposed input and output couplings and for electrically connecting input couplings of adjacent elements.
