Described herein methods of manufacturing dual-sided packaged electronic modules that control the distribution of an under-fill material between one or more components and a packaging substrate. The disclosed technologies include under-filling one or more components and deflashing a portion of the under-fill to remove under-fill material prior to attaching solder balls.

An online system presents a user with a content item including an image and text. The online system overlays the text on the image if it predicts doing so will not render the text unreadable. To predict whether the overlay will render the text unreadable, the online system computes values describing various visual characteristics of a segment of the image on which the text may be overlaid and compares the values to corresponding threshold values. Based on the comparison, the online system predicts a readability of the text if overlaid on the segment. If the predicted readability is at least a threshold readability, the online system overlays the text on the segment of the image and presents the content item to the user with the text overlaid on the image. Otherwise, the online system presents the content item to the user with the text not overlaid on the image.

A matched array technology system and method for displaying in a two-dimensional array the structured interaction between the expectations of manager and employee in an organization. Proxy values of employee and manager perspectives are defined and scaled so the axes of the array contain corresponding indicators resulting in a “matched array” and an embedded, unique “alignment vector” of the cells where employee and manager expectations are equivalent. The matched array display shows all possible manager and employee value intersections, and the geometry of the alignment vector designates optimal alignment between employee and manager for each stage of job performance from entry to advancement. The plotted position of an employee on the array in relation to its location and distance from the alignment vector measures employee performance, potential, and risk, and indicates the direction and extent of adjustment needed by either employee or manager to achieve and maintain alignment.

Computer method and system draws a 3D object, by sketching at least one first stroke (ST1) in a first plane (PL1) rendered in a first viewing frustum corresponding to a first pose of a virtual camera. The first plane (PL1) is orthogonal to a second (PL2) and a third plane (PL3). In response to a command of a user switching from the first pose to a second pose of the virtual camera, the method and system switches from the first viewing frustum to a second viewing frustum corresponding to the second pose of the virtual camera. The second viewing frustum is bounded by a near plane on the side of the virtual camera. Next a plane is selected as current drawing plane. The selected plane is among the first (PL1), the second (PL2) and the third plane (PL3), whose normal is the closest to the normal of the near plane. At least one second stroke (ST2) is then sketched in the current drawing plane.

The image processing device includes a scale correction unit. In a case where a difference between a width of a lane calculated by a lane-width calculation unit and a width of the lane acquired from map data is greater than a predetermined value that serves as a criterion for correcting errors, the scale correction unit corrects a correlation between a length of a subject in a captured image and the number of pixels constituting the captured image.

In one embodiment, a system of an ADV perceives an object in a perspective view of the ADV using a plurality of sensors mounted on the ADV including capturing an image of the object. The system determines a two-dimensional (2D) bounding box for the object and a perceived distance from the ADV to the object. The system searches, within an image space of the image, a dynamic pitch angle based on the 2D bounding box and the perceived distance from the ADV to the object by modifying at least a previous extrinsic calibration value to calculate a distance. The system determines a distance from the ADV to a point on a ground plane of the perspective view of the ADV based on the determined dynamic pitch angle. The system generates a driving trajectory based on the determined distance for the point on the ground plane to control the ADV.
