  • Patent number: 10267477
    Abstract: A lighting module for a motor vehicle includes a first light source and a first collimator for generating a first light beam of “low beam” type in collaboration with a first projection lens. Also included are second and a third light sources, the second light source collaborating with a second collimator to generate a first beam complementing the first light beam in order to form a second light beam of “high beam” type. In order to reduce the visibility of a cut-off zone in the second beam, the third light source collaborates with a third collimator and/or a second projection lens in order to form a second complementary beam which at least partly overlaps the cut-off zone. A front headlight for a motor vehicle can include such a lighting module.

  • Patent number: 10236805
    Abstract: Methods and systems for controlling an electric motor are provided. An electric motor controller is configured to be coupled to an electric motor. The controller includes a rectifier, an inverter coupled to the rectifier, and a control unit coupled to the inverter. The rectifier is configured to rectify an alternating current (AC) input voltage to produce a pulsed direct current (DC) voltage that drops to approximately zero during each cycle when the AC input voltage transits zero. Energy is stored on a load coupled to the motor when AC input voltage is available. The inverter is configured to receive the DC voltage and to provide a conditioned output voltage to the motor. The control unit is configured to manage energy transfer between the motor and the load such that the motor generates positive torque when the DC voltage supplied to the inverter has approximately 100% voltage ripple.
