  • Patent number: 11698034
    Abstract: A method of transient control for enrichment operation in a low-temperature combustion engine. The method includes determining if a current mode of the low-temperature combustion (LTC) engine is a positive valve overlap (PVO) mode. Determining if a previous mode of the LTC engine was also the PVO mode when the current mode is the PVO mode, wherein the previous mode is immediately prior to the current mode. Determining if the previous mode of the LTC engine was a negative valve overlap (NVO) mode when the previous mode was not the PVO mode. Initiating a predetermined enrichment PVO mode for the LTC engine based on the previous mode of the LTC engine. The predetermined enrichment PVO mode includes initiating a deep enrichment PVO mode, when the previous mode of the LTC engine was the NVO mode, and initiating a shallow enrichment PVO mode, when the previous mode of the LTC engine was not the NVO mode.

  • Patent number: 11699942
    Abstract: A method for manufacturing an electro-mechanical device includes creating a plurality of substrates using a first additive manufacturing process. Each of the substrates includes a polymeric material. The substrates include a first substrate and a second substrate. The first substrate includes a first main body and defines a protrusion extending from the first main body. The second substrate includes a second main body and a recess defined in the second main body. The method includes coupling the first substrate to the second substrate by inserting the protrusion into the recess such that the protrusion elastically deforms to an elastically averaged configuration. The protrusion and the recess together form an elastic averaging coupling. The method includes creating a plurality of electrically conductive components using a second additive manufacturing process and then coupling the electrically conductive components to at least one of the substrates.

  • Patent number: 11698445
    Abstract: A vehicle, Lidar system for the vehicle and method of scanning an object with the Lidar system. The Lidar system includes a first quarter wave plate, a first deflection stage and a detector. The first quarter wave plate produces a circularly polarized scanning beam of light. The first deflection stage selects a rotation direction for a polarization vector of the scanning beam and deflects the scanning beam by a selected angle based on the selected rotation direction of the polarization vector. The detector receives a reflected beam that is a reflection of the scanning beam from the object.

  • Patent number: 11698452
    Abstract: Vehicles and methods for tracking an object and controlling a vehicle based on the tracked object. A Radar-Doppler (RD) map is received from the radar sensing system of the vehicle and relative acceleration of an object with respect to the vehicle is detected based on the RD map so as to provide acceleration data. A current frame of detected object data is received from a sensing system of the vehicle. When the relative acceleration has been detected, a tracking algorithm is adapted to reduce the influence of the predictive motion model or the historical state of the object and the object is tracked using the adapted tracking algorithm so as to provide adapted estimated object data based on the object tracking. One or more vehicle actuators are controlled based on the adapted estimated object data.

  • Patent number: 11698675
    Abstract: An autonomous vehicle including a projector and a sensor system configured to output data representative of an object in an environment exterior of the autonomous vehicle. The autonomous vehicle can further include a data store that stores height map data. A computing system of the autonomous vehicle can classify an object as a person and can detect an initial position of the person. Responsive to the detection, the computing system can calibrate a notification to be projected on a ground of the environment exterior of the autonomous vehicle. The notification is based on output of a transform from a position of the projector to the ground and the transform is applied based on the predefined height map of the ground. The notification can be projected adjacent the person. The notification may be configured to inform the person that the autonomous vehicle detects a position of the person.
