With a total of two patents to his name, Colineau's work has had a lasting impact on technology.

Latest Patents

Colineau's latest patents include an innovative electric circuit designed for converting an AC voltage into a DC voltage. This circuit features a switch that is controlled to conduct for a specific period, depending on the desired output voltage. The control of the output voltage is linked to an instruction or reference signal, with the measuring signal being the mean value of the voltage at the switch's terminals during the AC voltage period. An integrator is utilized to establish this mean value by receiving the voltage signal at the terminals of the controlled switch.

Another significant patent is a generator for producing a DC supply voltage in a television receiver. This invention involves a circuit that produces current for the vertical deflector of a transistorized color television receiver. The circuit comprises an active switch that is controlled and modulated at the line frequency, supplied by line retrace pulses from the secondary winding of a line transformer. The voltage at the terminals of a capacitor in series with the vertical deflector maintains a constant sign, independent of the current passing through the deflector.
