Abstract: A method for detecting damage and determining a type of damage and a degree or severity of damage to a component of a transmission. The method includes providing a first image of a portion of the component in a reference state and detecting a further image of the portion of the component after intended use. The further image of the portion of the component is detected in an installed state of the component. The method further includes determining, by comparing the further image with the first image, that the component is damaged, determining, by matching the further image against data of a damage database, a type of damage, and outputting the determined type of damage and a degree or severity of damage. The first image, the further image, and the data of the damage database are photographs.

Abstract: A cervical plate assembly is disclosed. The cervical plate assembly includes a base plate including: (1) at least two bone screw seats, each bone screw seat including a borehole dimensioned to receive a bone screw, and (2) a first blocking seat positioned between the at least two bone screw seats. The cervical plate assembly includes a blocking mechanism retained within the first blocking seat of the base plate. The blocking mechanism is selectively positionable between a closed position in which the blocking mechanism obstructs at least one bone screw seat to retain a bone screw with the base plate, and an open position in which the bone screw seats are unobstructed.

Abstract: A multi-element problem may be solved iteratively by using a modified genetic algorithm to generate a plurality of solutions according to a set of solution criteria. The solution criteria may comprise a plurality of servers, each server including one or more attributes, and an indication of which of the one or more attributes are to be optimized. An index may be appended, by a processing device, to each solution in the plurality of solutions and the values in each solution may be sorted. For each solution in the plurality of solutions, one or more values from the solution may be combined with one or more values from another solution to generate a plurality of child solutions. Each child solution may have an index, and the values in each child solution may be sorted in view of the child solution's index. For one or more child solutions in the plurality of child solutions, two selected values may be rearranged to generate one or more mutated child solutions.

Abstract: A method for calibrating a visual-inertial tracking system is described. A device operates the visual-inertial tracking system without receiving a tracking request from a virtual object display application. In response to operating the visual-inertial tracking system, the device accesses sensor data from sensors at the device. The device identifies, based on the sensor data, a first calibration parameter value of the visual-inertial tracking system and stores the first calibration parameter value. The system detects a tracking request from the virtual object display application. In response to the tracking request, the system accesses the first calibration parameter value and determines a second calibration parameter value from the first calibration parameter value.

Abstract: A method and apparatus of tracking poses of a rolling-shutter camera in an augmented reality (AR) system is provided. The method and apparatus use camera information and inertial sensor readings from Inertial Measurement Unit (IMU) to estimate the pose of the camera at a reference line. Thereafter, relative pose changes at scanlines may be calculated using the inertial sensor data. The estimated reference pose of the camera is then further refined based on the visual information from the camera, the relative pose changes and the optimized reference line pose of a previous image. Thereafter, the estimate of the scanline poses may be updated using the relative pose changes obtained in the earlier steps.

Abstract: Visual-inertial tracking of an eyewear device using a rolling shutter camera(s). The eyewear device includes a position determining system. Visual-inertial tracking is implemented by sensing motion of the eyewear device. An initial pose is obtained for a rolling shutter camera and an image of an environment is captured. The image includes feature points captured at a particular capture time. A number of poses for the rolling shutter camera is computed based on the initial pose and sensed movement of the device. The number of computed poses is responsive to the sensed movement of the mobile device. A computed pose is selected for each feature point in the image by matching the particular capture time for the feature point to the particular computed time for the computed pose. The position of the mobile device is determined within the environment using the feature points and the selected computed poses for the feature points.

Abstract: The disclosure relates to a method for controlling an internal combustion engine. The internal combustion engine includes a cylinder and a piston, which runs in the cylinder, together delimiting a working chamber. The working chamber is supplied with fresh air from an intake section via an inlet valve and is connected to an exhaust manifold via exhaust valves. The internal combustion engine includes a variable valve actuation system for the actuation of the inlet valves, controlling the opening time and/or the closing time and/or the lift. A strategy for shutting down the internal combustion engine includes controlling the inlet valves of individual or all working chambers in such a way that the transfer of fresh air from the intake section to the exhaust manifold is reduced or avoided and that the drag torque of the intake combustion engine is reduced.

Abstract: A method for monitoring a condition of a sliding bearing operated with lubricating oil for a rotating component includes calculating, by a control unit as an output variable of a sliding bearing model, a calculated value of a minimum gap thickness of the sliding bearing. The calculated value is calculated by orbit analysis from at least one physical sliding bearing model to which at least a rotational speed of the rotating component, a bearing load, and a temperature of the sliding bearing are supplied as input variables. The method further includes measuring, with at least one sensor, a minimum gap thickness to provide a measured value of the minimum gap thickness, and comparing the measured value of the minimum gap thickness with the calculated value of the minimum gap thickness for the purpose of adjustment.
