Problem detection for cable-fed-loads

A method for detecting a problem in at least one of a plurality of loads coupled to a cable of a cable system, the method comprising steps of:

• sensing a cable signal in response to a signal being offered to the cable, using a cable interface coupled to the cable system, wherein the cable signal is a feeding signal or a simulated feeding signal that supplies power to the cable system, wherein the waveform includes crests and troughs and wherein respective loads of the plurality of loads are coupled to the cable via respective drivers at respective locations;
• storing at least a waveform of the cable signal feeding the plurality of loads;
• analyzing, using a processor coupled to the cable interface, the waveform of a cable signal to determine whether the problem in the at least one of the plurality of loads is present or not without receiving a message or communication from any of the loads and without modification or direct coupling to any of the loads;
• amending, when a problem in a load occurs, using a corresponding driver, at least one value of the waveform at or near at least one of the crests and the troughs, and
• determining, using the processor, whether the waveform has been amended by more than a threshold.

A non-transitory computer readable storage medium including a computer program including a set of instructions executable by a processor to detecting a problem in at least one of a plurality of loads coupled to a cable of a cable system, the computer readable storage medium comprising code for:

• sensing a cable signal in response to a signal being offered to the cable, using a cable interface coupled to the cable system, wherein the cable signal is a feeding signal or a simulated feeding signal that supplies power to the cable system, wherein the waveform includes crests and troughs and wherein respective loads of the plurality of loads are coupled to the cable via respective drivers at respective locations;
• storing at least a waveform of the cable signal feeding the plurality of loads;
