Abstract: A medical system comprises an elongate device, an elongate sheath configured to extend within the elongate device, and an imaging probe configured to extend within the elongate sheath. The elongate sheath includes an identification feature. The medical system further comprises a control system configured to receive imaging data from the imaging probe. The imaging data is captured by the imaging probe. The control system is further configured to analyze the imaging data to identify an appearance of the identification feature within the imaging data. The control system is further configured to, based on the appearance of the identification feature, register the imaging data to a reference frame of the elongate device.

Abstract: A tractor cab suspension system includes a plurality of suspension members arranged for supporting the cab on the frame in which some of the suspension members at one end of the cab comprise resilient members compressed between the cab and the frame of the tractor and other ones of the suspension members at the other end of the cab comprise air cushion members. A rollover protection member is associated with each air cushion member to resist separation of the cab from the frame at the cushion member during a rollover of the tractor. The rollover protection members are arranged to couple the cab and the frame for linear sliding movement relative to one another.
