  • Patent number: 11950994
    Abstract: An applicator instrument for dispensing surgical fasteners includes a housing, and an elongated shaft extending from the housing. The elongated shaft has a proximal end secured to the housing, a distal end spaced from the proximal end, and a first axis extending between the proximal and distal ends of the elongated shaft. Surgical fasteners are disposed in the elongated shaft. The surgical fasteners are stacked at an angle relative to the first axis of the elongated shaft. A distal end cap having a surgical fastener dispensing window is secured to the distal end of the elongated shaft. The applicator instrument has a firing system disposed in the housing, and an actuator coupled with the firing system for activating the firing system to dispense the surgical fasteners through the surgical fastener dispensing window.

  • Publication number: 20230396324
    Abstract: In an embodiment, a user terminal includes a communication module (CM) configured to generate an initial network entry request; an antenna assembly configured to find, in response to the initial network entry request, a satellite based on a search of a sky. The search of the sky includes sequentially changing a beam pointing direction of the antenna assembly. The satellite is assigned to downlink to a geographic cell associated with the user terminal. The user terminal includes a media access control (MAC) layer component configured to generate an uplink radio frame including a random access channel (RACH) request associated with the initial network entry request at a particular portion of the uplink radio frame for the satellite.
