Latest Patents

One of Grimaud's latest patents is a device for triggering an event in phase with the angular position of a rotary component. This invention utilizes an encoder that delivers a pulse input signal in phase with equal angular steps of a toothed wheel driven by the crankshaft of an internal combustion engine. A missing tooth defines a reference position, at which a synchronizing signal is also delivered. The invention includes a counter that is incremented by the pulse input signal and reset by the synchronizing signal. A comparator then compares the count in the counter with a number in a memory circuit to trigger an event when the counts coincide.

Another significant patent involves a process and device for sending electrical current into a circuit using a transistor. This invention enables the electrical powering of a circuit with a conductor that has high thermal inertia, utilizing a transistor with low thermal inertia. The device comprises a current limiter circuit, a voltage detector circuit, and a control microprocessor that manages the flow and stoppage of current in the power transistor. This innovation has applications in controlling lights in automobile vehicles.
