Abstract: Systems and techniques are described herein for user identification. For instance, a technique can include receiving at least one biosignal from a sensor, the at least one biosignal indicative of a blood perfusion of a user. The technique can further include extracting at least one feature from the at least one biosignal, comparing the extracted at least one feature to at least one template feature associated with an enrolled user, determining, based on comparing the extracted at least one feature to the at least one template feature, whether the user matches the enrolled user, and outputting an indication of whether the user matches the enrolled user.

Abstract: Disclosed herein are integrated circuit (IC) interconnects, as well as related devices and methods. For example, in some embodiments, an interconnect may include a first material and a second material distributed in the first material. A concentration of the second material may be greater proximate to the top surface than proximate to the bottom surface.

Abstract: Embodiments of the present disclosure describe techniques for oxidizing plasma post-treatment for reducing photolithography poisoning. In one embodiment, an apparatus includes a dielectric layer with a plurality of routing features; and an etch stop layer, having a first interface region coupled with the dielectric layer and a second interface region disposed opposite to the first interface region. The first interface region has a peak silicon oxide (SiO2) concentration level evenly distributed across the first interface region, and the second interface region has substantially zero silicon oxide (SiO2) concentration level. Other embodiments may be described and/or claimed.

Abstract: A game playing apparatus includes a center pole having at least first, second and third nets radially extending therefrom and attached at their ends to end poles. A boundary line extends between the end poles so as to define a circular playing surface divided into three equal area sectors, each sector defining a court for a team. The game is preferably volleyball by which one team competes against the other two teams via conventional volleyball rules. Each team may hit the volleyball over either one of the two nets defining its sector in a manner to preclude return by the other team. The extensible center pole and end poles include collars slidable therealong allowing for adjustment of the net heights. A guide on the center pole indicates a path of initial extension of each net away from the center pole preferably at 120.degree..

Abstract: An apparatus for launching stores from a recess of a vehicle submerged in a arine environment includes a capsule having an elongated body of rectangular cross section for enclosing the stores. A structure for providing hydrodynamic stability to the capsule is joined thereto, the capsule and stabilizing structure together being receivable into the recess. The apparatus is further provided with a first hatch for sealing the recess from the marine environment when the apparatus is received thereinto.
