  • Patent number: 12687252
    Abstract: A corrosion resistant tube includes a tubular low carbon steel body having an inside surface and an outside surface, a corrosion resistant metal coating on the inside surface, a first corrosion resistant metal coating on the outside surface, a second corrosion resistant metal coating applied to the first corrosion resistant metal coating on the outside surface, and a polymer layer applied over the second corrosion resistant metal coating. A method of manufacturing a corrosion resistant tube, includes applying a corrosion resistant metal coating both sides of a strip of low carbon steel, forming the strip into a tube and welding the edges to form a tubular body. The weld is narrower at the inside surface than at the outside surface of the tubular body. The corrosion resistant metal coating on the inside surface is heated during welding and flows across and covers the weld.

  • Publication number: 20260109385
    Abstract: A car seat and stroller combination system includes a pair of front legs and a pair of back legs. The front legs and the back legs are designed such that they fold in an accordion-style configuration. In the unfolded state, the front legs are toward a front side of the car seat and stroller combination system and the back legs are toward a back side of the car seat and stroller combination system. However, in the folded state, the front legs are toward the back side of the car seat and stroller combination system and the back legs are toward the front side of the car seat and stroller combination system. The car seat and stroller system includes a handle than can be rotated in multiple positions and telescoped in or out by actuating a same button.

  • Patent number: 12584088
    Abstract: A cell culture bag includes a body formed of a composite film including a first fluoropolymer and a second fluoropolymer. The body defines a cell culture compartment configured to hold a cell culture. The first fluoropolymer has a first thickness and the second fluoropolymer at least partially impregnates the first thickness of the first fluoropolymer. The composite film has a second thickness from 0.01 mm to 0.059 mm and a tensile strength in one direction of 10,000 psi to 92,000 psi. The composite film also has O2 flux of 2,000 cm3/m2/atm/day to 20,000 cm3/m2/atm/day and a total transmittance from 70% to 100%. A cell culture assembly includes a plurality of the cell culture bags connected in series. A cell culture container includes a cell culture compartment and a composite film connected to the cell culture compartment, the composite film including a first fluoropolymer and a second fluoropolymer.

  • Publication number: 20260069261
    Abstract: An implantable medical device for sealing and repairing defects in a body tissue or for creating an anastomosis includes a frame and a covering material. In some embodiments, the frame includes a single continuously wound wire that defines an apposition portion, a defect-occupying portion, and a sealing portion. In some embodiments, the tissue-sealing and anastomosis devices provided herein are well-suited for use in the GI tract including the small bowel and colon. In some embodiments, a two-part frame construct facilitates independent tailoring of apposition forces and radial forces exerted on tissues by the two-part frame.

  • Patent number: 12538213
    Abstract: A method for applying per-International Mobile Subscriber Identification (IMSI) Access Point Name (APN) Operator Identifier (OI) replacement for Multiple IMSI Multiple Mobile Subscriber Integrated Service Digital Network (MSISDN) subscribers comprises receiving, at a home subscriber server of a cellular network, an identification of a currently active IMSI for a cellular device. The cellular device is associated with a cellular service subscriber having multiple IMSIs and multiple MSISDNs, the multiple IMSIs comprise a primary IMSI and one or more secondary IMSIs, and each of the IMSIs has an associated roaming COS that includes a roaming restriction policy that allows or suppresses Voice Over LTE (VOLTE). In response to the currently active IMSI for the cellular device being a secondary IMSI, the method comprises applying the roaming restriction policy specified in the roaming COS of the secondary IMSI regardless of the roaming COS of the primary IMSI.

  • Publication number: 20260008302
    Abstract: A stroller handlebar actuator is provided. The handlebar actuator is provided at a handlebar of the stroller and includes cables that are attached to the handlebar actuator at one end and rear wheels of the stroller at another end. The handlebar actuator includes a protruding tab that a user to able to press using one or both thumbs without needing to remove their hands from the outer ends of the handlebar. By pressing the tab, a rotational force is exerted on the handlebar actuator, causing the handlebar actuator to rotate relative to the handlebar. This rotation causes the cables to pull inwards towards the handlebar actuator, thereby unlocking mechanisms provided at the rear wheels. The unlocking of the mechanisms causes the rear wheels to be able to freely rotate about a vertical axis. When the force is removed from the handlebar actuator, the handlebar actuator rotates back to its natural resting position and the cables return back to their original positions, locking the rear wheels.

  • Publication number: 20250187695
    Abstract: A ride-on device with multiple modes and functions is provided. The ride-on device (e.g., ride-on toy) may transition between multiple modes such as a stroller mode with a seat and a pusher handle, a tricycle mode with a seat and a set of pedals on a front wheel, and a scooter mode with handle connected to a front wheel and a base for standing connected to the front wheel and having a set of back wheels. The ride-on device may include a base having multiple portions that may rotate with respect to one another to transition between the stroller, tricycle, and/or scooter modes. The ride-on device may include a wheel assembly with wheels that may be moved between different wheel positions. In one example, the wheel assembly may be rotated with respect to the base such that the base is positioned above the wheel assembly.
