An access point device selects a group of two or more transceivers from a plurality of transceivers for simultaneous transmission of respective data to the access point device. The flange has a joint to which a separation jig is applied to apply a tensility in a direction of separating the flange from the cylindrical substrate. The projection of the bores through the ring seal form sidewalls which project between the axial end surfaces and radially from the ring seal’s radial outer surface towards the ring seal’s radial inner surface. The chassis includes a sidewall. The method further includes projecting slack using the correlation between the at least two parameters and using a processor. The present invention also relates to a Lactuca sativa plant produced by growing the 79-51 RZ seed.
