Election/Restrictions Applicant's election with traverse of fig. 16) and claims generic thereto (i.e., claims 1-26) in the reply filed on 02/27/2026 is acknowledged. The traversal is on the ground(s) that fig. 16 embodiment is a structural schematic that builds cumulatively upon all of the features introduced in the earlier embodiments (including figs. 1, 2, 5, and 6), and it further introduces the second signal line L2 and second crossing line 20 as an additive feature. The species thus cannot be considered to have mutually exclusive characteristics when one species fully encompasses the features of another. This is found persuasive and the restriction requirement is withdrawn.
