Assignee | ECOSENSE LIGHTING INC., Los Angeles, CA (US) |

1. A system for determining periodic values of a phase angle (?) of a waveform power input, comprising:a voltage detector for receiving a phase-cut waveform power input, the voltage detector being configured for generating a plurality of periodic values of an average voltage (V-ave) of the phase-cut waveform power input and for generating a corresponding plurality of periodic values of a peak voltage (V-peak) of the phase-cut waveform power input; and

a phase angle (?) detector being in signal communication for receiving the periodic values of the average voltage (V-ave) and the peak voltage (V-peak) from the voltage detector and being configured for: generating a plurality of periodic values each being a ratio (V-ap) of one of the plurality of periodic values of the average voltage (V-ave) divided by the corresponding one of the plurality of periodic values of the peak voltage (V-peak); and determining a plurality of periodic values of a phase angle (?) of the phase-cut waveform power input each corresponding to one of the plurality of periodic values of the ratio (V-ap).
