Abstract: Package structures and methods for manufacturing the same are provided. The package structure includes a first bump structure formed over a first substrate. The first bump structure includes a first pillar layer formed over the first substrate and a first barrier layer formed over the first pillar layer. In addition, the first barrier layer has a first protruding portion laterally extending outside a first edge of the first pillar layer. The package structure further includes a second bump structure bonded to the first bump structure through a solder joint. In addition, the second bump structure includes a second pillar layer formed over a second substrate and a second barrier layer formed over the second pillar layer. The first protruding portion of the first barrier layer is spaced apart from the solder joint.

Abstract: A method may include receiving, from a camera, image data representing an object in an environment and determining, based on the image data, a vertical position within the image data of a bottom of the object. The method may also include determining an object bottom ratio between the vertical position and a height of the image data and determining, by way of a distance projection model and based on the object bottom ratio, an estimate of a physical distance between the camera and the object. The distance projection model may define, for each respective candidate object bottom ratio of a plurality of candidate object bottom ratios, a mapping between (i) the respective candidate object bottom ratio and (ii) a corresponding physical distance in the environment. The method may additionally include generating an indication of the estimate of the physical distance between the camera and the object.

Abstract: A detecting method for repetitive motion includes receiving a plurality of accelerated velocities, receiving a plurality of angular velocities, determining a plurality of stationary points according to the accelerated velocities, determining a plurality of motion periods according to the stationary points, wherein the motion periods separately correspond to different sets of the angular velocities, and clustering the motion periods according to differences among the different sets of angular velocities corresponding to the motion periods.
