Abstract: The present disclosure primarily relates to interceptor unmanned aerial systems and methods for countering Unmanned Aerial Systems (UAS), although the inventions disclosed herein are useful for capture of any aerial object. The system utilizes a rigid effector frame, an effector attached directly to the frame, and at least two propulsion elements connected to the effector frame, and is configured to intercept and disable threat UAS. The disclosed systems can be oriented to any virtually any angle to maximize the chances of intercept.

Abstract: In a method producing an electronic circuit includes analyzing pre-register-transfer level phase of a power distribution network in an electronic circuit design. The power distribution network is defined to include a matrix of a number repeated leaf cells, wherein each of the matrix of repeated leaf cells corresponds to a model leaf cell wherein the model leaf cell includes an alternating Vdd and Gnd grid on top of an interposer. A plurality of local ports of the model leaf cell is defined. The plurality of local ports is defined where each of the matrix of repeated leaf cells is coupled to adjacent ones of the matrix of repeated leaf cells. The model leaf cell is simulated using an implementation of an integral equation based solver to compute electromagnetic scattering parameters (S-parameters) that correspond to the model leaf cell. The electromagnetic S-parameters are cascaded across the matrix using a binary merge algorithm.

Abstract: Disclosed herein is an apparatus and a method to use such an apparatus for visualizing the contraction stress from curable materials. Particularly, a simple test device has been designed and fabricated and a method of using such a device, which allows a user to easily distinguish the curable materials that can generate contraction stress in different magnitudes. More specifically, the present disclosure provides a simple and effective way to make the complicated contraction stress due to polymerization (curing or setting) visualizable and audible.

Abstract: Golf training glasses to assist a golfer's swing and ball connection comprising an inner (base) frame and an outer frame without lenses. The outer frame has separate sight-guides for each eye that are connected to threaded guide posts on the left and right sides of the frame and are designed as hollowed rectangles with the upper and lower ridges creating an optical viewing channel. This channel acts as a pathway to frame in the golf ball, the golf club and the hole enabling a golfer to align and strike the ball in a straight path to the hole from back-swing to follow-through. The sight-guides critically adjust up and down the guide posts independently of each other by tracking wheels on each post to accommodate for the inter-pupillary distance or pupil height which is different for each eye of each golfer. The outer frame is attached to the base frame by a hinged clip and can be flipped up or detached from the base frame entirely when not in use.

Abstract: A papermaker's fabric, usable in the forming section of a paper machine, has first and second layers of cross-machine direction (CD) yarns interwoven with sets of machine-direction (MD) yarns. Each set has four pairs of MD yarns with each pair comprising a first MD yarn and a second MD yarn. The first and second MD yarns each cross between and weave with both the first and second layers of CD yarns. In the MD, each pair effectively produces a four-shed contour in the first layer and a two-shed contour in the second layer. Each pair is shifted in the CD, such that 4 pairs of MD yarns combine to effectively produce a four-shed contour in the CD in the first layer.

Abstract: An improved cervical collar having an elongated neck encircling band secured to a two-piece chin support brace wherein each end of each of the two pieces of the chin support brace are permanently secured to the elongated encircling band body.

Abstract: A security device for buildings comprises a barricade including a metal frame with a metal gridwork anchored thereto and extending across and covering the interior frame opening. The frame is configured to fit within a doorway or window opening. At least one positioning bar is disposed on one side of the frame and extends outward therefrom to beyond the frame perimeter, said positioning bar configured for placing into a receiving slot formed in the interior perimeter of the doorway or window opening. A locking bar is slidably journalled within guide track openings formed in guide tabs which are secured to the barricade. Said locking bar includes at least one perimeter locking end for slidable entry into a receiving slot formed in the interior perimeter of the doorway or window opening.
