Abstract: A method performed by a WTRU may comprise receiving a plurality of LBT configurations associated with one or more of a beam, a BWP, a LCH, a set of LBT parameters, a transmission type or an LBT subband. The method may further comprise receiving an indication to transmit using a first LBT configuration of the plurality of LBT configurations. An attempt to acquire a channel may then be made using the first LBT configuration. The indication to transmit may additionally indicate a second LBT configuration of the plurality of LBT configurations. Data may be transmitted on the channel when the attempt to acquire the channel is successful. An attempt to acquire the channel using the second LBT configuration of the plurality of LBT configurations may be made when the attempt to acquire the channel using the first LBT configuration fails.

Abstract: An aircraft fuel tank system including a fuel tank compartment for containing liquid fuel and having a float-activated valve arranged to become positively buoyant when immersed in liquid fuel so that the float moves up to a raised position which causes the valve to close and prevent liquid fuel from flowing out of the fuel tank compartment through the valve. The float is also arranged to move down to a lowered position in response to a level of the liquid fuel in the fuel tank compartment dropping, the movement of the float to the lowered position causing the valve to open and permit liquid fuel to flow out of the fuel tank compartment through the valve. A pressure-activated valve may be used as an alternative to the float-activated valve.

Abstract: A mounting apparatus for mountable devices such as speakers. Preferably two device mounting members are fixed to a speaker and two fixed mounting members are fixed to a wall. The speaker is then moved horizontally so that the device mounting members releasably snap into engagement with the fixed mounting members. The speaker can be rotated left/right and locked in position. The speaker can be installed and uninstalled by a single person.

Abstract: A positionable connector assembly comprises a base, a connector operatively connected to the base, a friction member positioned between the base and the connector, and a biasing member operatively connected to the connector and configured and arranged to bias the connector toward the friction member.

Abstract: The present disclosure is directed to a retention assembly for a gas turbine component including a first and a second gas turbine wall respectively defining a first and a second surface. A retainer, positioned between the first and the second surfaces, includes a flange, which contacts the first surface. A plurality of fingers extends outwardly from the flange.
