Abstract
An electronic system is disclosed for an associated electrical apparatus, the system having at least a binary input adapted to receive one or more candidate signals; at least an electronic active load having one or more electronic active devices and operatively connected to the binary input; and a controller operatively associated to the binary input and to the active load. The controller can detect application of a candidate signal to the binary input and electrically drive the active load upon such detection; and after absorption of a predetermined amount of energy, validate the candidate signal if its residual content of energy exceeds a predetermined threshold.
Claims20
An electronic system for an associated electrical apparatus, comprising:
- at least a binary input adapted to receive one or more candidate signals;
- at least an electronic active load having one or more electronic active devices and operatively connected to said binary input;
- and
- control means which are operatively associated to said binary input and to said active load, and which are configured to:
- detect application of a candidate signal to the binary input and electrically drive said active load upon said detection, such that the active load will absorb at least a predetermined amount of energy from the candidate signal;
- and
- after absorption of said predetermined amount of energy validate the candidate signal if its residual content of energy exceeds a predetermined threshold.
A method for validating a candidate signal applied to a binary input in an electronic system associated to an electrical apparatus, said method comprising:
- operatively connecting at least an electronic active load having one or more electronic active devices to said binary input;
- detecting application of said candidate signal to the binary input;
- electrically driving said active load to absorb at least a predetermined amount of energy from the candidate signal upon detection of the application of said candidate signal;
- and
- after the absorption of said predetermined amount of energy, validating the candidate signal if its residual content of energy exceeds a predetermined threshold.
