  • Publication number: 20230137253
    Abstract: An apparatus comprises a toggle member, a plurality of pogo pins, and a test board in operable communication with the toggle member. The pogo pins are coupled to the toggle member to move along a first axis when the toggle member moves along the first axis. Each pogo pin includes a plunger that moves within the pogo pin along the first axis. The pogo pins and respective plungers contact a top surface of the DUT when the DUT is coupled to the test board and positioned so that a conductor on its outer surface is aligns to and contacts a conductive region of the test board. Movement of the toggle member along the first axis translates to the plungers, applying a pressure sufficient to the top surface of the DUT to ensure flushmount electrical contact between the conductor of the DUT and the conductive region.

  • Patent number: 11297066
    Abstract: Described are techniques for an access management protocol including a method comprising associating a granted permission set and a constrained permission set to a user profile in an access management system. Respective granted permissions in the granted permission set authorize the user profile to perform the respective granted permissions, and respective constrained permissions in the constrained permission set preclude the user profile from performing the respective constrained permissions. The method further comprises receiving a permission-based request at the access management system and from the user profile and determining that the permission-based request is associated with a permission that is included in both the granted permission set and the constrained permission set. The method further comprises rejecting the permission-based request.

  • Publication number: 20220090168
    Abstract: The present invention provides an oligonucleotide composition including a blocker and a first primer oligonucleotide. The blocker oligonucleotide includes a first sequence having a target-neutral subsequence and a blocker variable subsequence. The non-target specific subsequence is flanked on its 3? and 5? ends by the target-neutral subsequence and is continuous with the target-neutral subsequence. The first primer oligonucleotide is sufficient to induce enzymatic extension; herein the first primer oligonucleotide includes a second sequence. The second sequence overlaps with the 5? end of the target-neutral subsequence by at least 5 nucleotides; herein the second sequence includes an overlapping subsequence and a non-overlapping subsequence. The second sequence does not include the non-target specific subsequence.

  • Publication number: 20220080635
    Abstract: An injection molded article includes: (a) an article first portion having internal threading extending helically about an article axis, the threading configured to be formed by a thread mold in a mold core; and (b) an article second portion spaced radially apart from the article first portion and connected to the article first portion by a connection portion. The article second portion has at least one ejection-assist rib configured to be formed by at least one rib mold feature in the mold core. The ejection-assist rib defines a helical slide surface extending helically about the article axis. During an initial unscrewing rotation of the molded article relative to the mold core, the rib mold feature of the mold core bears against the slide surface of the ejection-assist rib to urge the article second portion axially away from the mold core during ejection of the molded article from the mold core.
