  • Patent number: 9625021
    Abstract: An electric portal axle (1) for electrically driving a motor vehicle has a housing (28), a single electric machine (2) and two spur gear stages (13, 14) for driving two wheels of the axle. A shiftable transmission (5) is downstream of the electric machine (2) and is embodied as a planetary gear mechanism with a freewheel (6) and a differential (7). The portal axle (1) has a shifting mechanism (23) for shifting two gear stages of the portal axle (1). In a first gear stage, a ring gear (9) of the transmission (5) and a clutch body (27) that is fixed to the housing are connected, and a clutch (29) between the ring gear (9) and a planetary carrier (11) of the transmission (5) is opened.

  • Patent number: 9566852
    Abstract: A drive train (1) of an all-electrically drivable motor vehicle has a first axle (2) with a differential (6), and two electric machines (15, 16). The first axle (2) can be driven by the electric machines (15, 16) via a transmission (17). One (16) of the two electric machines (15, 16) can be decoupled from the transmission (17) via a switchable clutch (23). Different driving conditions of the motor vehicle operated by the drive train can be executed with a particularly good efficiency.

  • Patent number: 9443350
    Abstract: Embodiments disclosed facilitate resource utilization efficiencies in Mobile Stations (MS) during 3D reconstruction. In some embodiments, camera pose information for a first color image captured by a camera on an MS may be obtained and a determination may be made whether to extend or update a first 3-Dimensional (3D) model of an environment being modeled by the MS based, in part, on the first color image and associated camera pose information. The depth sensor, which provides depth information for images captured by the camera, may be disabled, when the first 3D model is not extended or updated.

  • Patent number: 9123135
    Abstract: A mobile device tracks a relative pose between a camera and a target using Vision aided Inertial Navigation System (VINS), that includes a contribution from inertial sensor measurements and a contribution from vision based measurements. When the mobile device detects movement of the target, the contribution from the inertial sensor measurements to track the relative pose between the camera and the target is reduced or eliminated. Movement of the target may be detected by comparing vision only measurements from captured images and inertia based measurements to determine if a discrepancy exists indicating that the target has moved. Additionally or alternatively, movement of the target may be detected using projections of feature vectors extracted from captured images.
