  • Publication number: 20260193913
    Abstract: A casement window and awning window opening control device for limiting the opening of a window having a hook arm assembly with a hook lock slidably mounted over a portion of a hook arm to restrict ingress and egress of a rivet pin into a receiving hook and rivet pin assembly having a pivot arm biased to a desired position so that when the window is opened the rivet pin is biased towards the frame away from the sash to ensure proper re-engagement of the receiving hook and rivet pin when the sash is opened, enhancing efficiency and ensuring safety.

  • Patent number: 12650033
    Abstract: A window combination latch (140) includes a sash lock (142) and tilt a latch assembly (230). The sash lock (142) installs on a top rail of a window sash (110) and includes a cam (214) that rotatably couples with a keeper (144) to lock the window sash (110). The cam (214) includes a slot (320). The latch assembly (230) when installed has a tip (422) of a latch bolt (232) adjacent to a surface of a stile (112) of the window sash (110) and a head (412) of the latch bolt (232) engaged in the slot (320). The latch bolt (232) may be a one-piece structure that may include a flexible extension (414).

  • Publication number: 20240231596
    Abstract: A plurality of video items comprising a first subset of video items and a second subset of video items are received at a client device. A graphical user interface comprising a scrollable area displaying the first subset of video items and a focus area displaying one of the plurality of video items is presented. Preview of video items of the second subset of video items is provided in or adjacent to the focus area in the GUI on the client device prior to receiving a scrolling request of a user of the client device to cause the second subset of video items to become visible in the first scrollable area. Video items of the second subset of video items are presented in the preview as GUI elements each comprising an icon representing a corresponding video item.

  • Patent number: 11941240
    Abstract: A plurality of video items comprising a first subset of video items and a second subset of video items are received at a client device. A graphical user interface comprising a scrollable area to present the plurality of video items and a focus area to present one of the plurality of video items is presented. Video items of the second subset of video items are presented in or adjacent to the focus area when the first subset of video items is visible in the scrollable area and prior to the second subset of video items becoming visible in the scrollable area, and a size of the video items from the second subset of video items presented in or adjacent to the focus area is smaller than a size of video items of the first subset of video items presented in the scrollable area.

  • Patent number: 11578238
    Abstract: Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest.

  • Patent number: 11409543
    Abstract: An information handling system includes a delay controller having an analytics engine configured to analyze telemetry data associated with an installation of a program, to calculate a confidence index based upon the analyzed telemetry data, and to generate a recommendation corresponding to the calculated confidence index. A download controller receives an end-user recommendation selection, and delays the installation of the program based upon a delay time in the received end-user recommendation selection.
