Abstract: A semiconductor device includes a first semiconductor die having a top planar surface and a second semiconductor die having a bottom planar surface and a top planar surface. A protective layer including a bottom planar surface and a top planar surface is positioned between the first semiconductor die and the second semiconductor die. An adhesive layer having a top planar surface and a bottom planar surface is between the protective layer and the second semiconductor die. A periphery of the top planar surface of the first semiconductor die is covered by a periphery of the bottom planar surface of the protective layer after cutting a portion of the protective layer that extended past the periphery of the surface of the first semiconductor die. The protective layer reduces the occurrence of peeling of the second semiconductor die and first semiconductor die coupled to the protective layer.

Abstract: An air filtration system includes a main body having a flow path; a first filter portion provided on the flow path and having a first body portion; a plurality of protrusions distributed and disposed on the first body portion; and a plurality of first through holes passing through the first body portion and interposed between the adjacent protrusions; wherein when an external fluid flows in the flow path, the external fluid passes through the protrusions first and then passes through each of the first through holes, so that the flowing external fluid is hindered by the protrusions, and thus a flow velocity at a position adjacent to the protrusions is lower than a flow velocity flowing through the first through holes, thereby vortices are respectively generated between orifices of the first through holes and the adjacent protrusions.

Abstract: Aspects of camera-based pallet placement detection and notification are described. An image is captured using a camera device. The image includes a pallet placement region within a field of view of a camera device. A pallet placement is detected by determining at least one orthogonal intersection between a plurality of position lines identified from the image. A user interface provides the detected pallet position to facilitate corrective measures.

Abstract: Charting a content distribution system (CDN) involves identifying a set of DNS servers that may be used as vantage points to test delay performance to a CDNs content server. As provided herein, to identify potential vantage point DNS servers, a set of authoritative name servers is identified and, from that set, those authoritative name servers that respond to a DNS query are identified as responsive authoritative name servers. Identifying a CDN content server that serves a particular vantage point DNS server involves retrieving an IP address for the CDN content server from a DNS query to the DNS server corresponding to the vantage point. The delay performance between the vantage point DNS server and the CDN content server can then be determined. Further, one can determine locations to deploy new data centers for a CDN based on delay performance, A delay from one or more vantage points to an existing CDN's DNS servers can be measured, and desired rank of locations can be generated.
