  • Publication number: 20240137100
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a polarization performance loss indication that is indicative of a loss in polarization performance based on transitioning from a first operating state associated with a first frequency range to a second operating state associated with a second frequency range, wherein the first operating state corresponds to a first antenna configuration and the second operating state corresponds to a second antenna configuration, wherein the first antenna configuration corresponds to a first antenna orientation and the second antenna configuration corresponds to a second antenna orientation. The UE may receive, from the network node, configuration information indicative of at least one communication parameter associated with the at least one antenna array and based on the polarization performance loss indication. Numerous other aspects are described.

  • Patent number: 11844687
    Abstract: A method of making an implantable prosthesis includes applying a gelling enhancer layer over an inner surface of a wall of a silicone shell having anterior and posterior walls surrounding an interior volume. The method includes filling the interior volume of the shell with a silicone gel and curing the silicone gel. The cured silicone gel that is located within a zone that is in the vicinity of the gelling enhancer layer has a higher level of cohesiveness than the cured silicone gel that is located outside the zone. The zone of the silicone gel having the higher level of cohesiveness has a thickness of 2-10 mm. The silicone gel located outside the zone has a first concentration level of a gelling enhancer and the silicone gel located within the zone has a second concentration level of the gelling enhancer that is 5%-300% greater than the first concentration level.
