Latest Patents

One of Fattic's latest patents is for a regenerative vehicle launch system. This hybrid electric vehicle design incorporates an internal combustion engine, a multi-speed automatic transmission, and an electric machine that operates in both motoring and generating modes. The innovative system utilizes a compound planetary gear set to connect the engine, transmission, and electric machine. During vehicle launch, the electric machine provides reaction torque to the planetary gearset, enabling torque to be supplied to the transmission's input. This reaction torque energy is then converted into electrical energy for storage in the vehicle's battery pack. The method employs a combination of open-loop torque control and closed-loop speed controls, which respond to various rotational parameters of the vehicle drivetrain, including engine speed and electric machine rotor speed.

Another significant patent by Fattic is for an optical sensor and the method of making it. This optical sensor features a gap for a toothed modulator wheel and accurately aligned optical fibers on either side of the gap. The design allows for a compact sensor structure, achieved by inserting a single optical fiber into a mold and supporting it in a U-shape. A thermosetting material is molded around the fiber to form a body, encapsulating the fiber while creating a gap by excluding resin from the straight portion of the fiber.
