Abstract: A trimming system for a user-operated ground vehicle capable of performing mowing and trimming operations. The system includes a drive operatively coupled to a drive system of the vehicle having the trimming system mounted thereon, and a trimming unit operatively coupled to the drive for performing edge trimming operations. The drive may include at least one driven pulley operatively coupled to a drive pulley of the vehicle for driving the trimming unit. The drive pulley may be coupled to a mowing unit and the trimming unit to either selectively or simultaneously drive the mowing and trimming units. A guide wheel may be mounted on the vehicle adjacent the trimming unit for maintaining the trimming wires of the trimming unit at a predetermined distance from a stationary object during performance of edge trimming operations.

Abstract: An interface that couples a surface coil array having N receiving elements to an NMR scanner having M preamplifier inputs. The interface includes an RF switch array and a transmit/receive bias circuit. The RF switch array and the transmit/receive bias circuit are controlled by a control logic circuit. In response to a predetermined input, the control logic circuit causes a predetermined subset of the N receiving elements to be couple to the preamplifier inputs of the NMR scanner. Preferably, N may be larger than M.

Abstract: A bezel panel mounting system height adjustably disposed within a plastic molded case for supporting panel supported equipment having corner pieces and rails disposed between the corner pieces. Each corner piece has two legs extending from a rounded endpoint which corresponds geometrically with a corner of the case, and having two male members opposite the endpoint on the legs for mating with a female feature on two ends of the rail. The panel is supported on a flat surface of the corner pieces and rails. A crevice is disposed adjacent flat surfaces and outer sides of each rail and corner piece for a gasket. Openings are disposed on the sides and flat surfaces of the rails and corners which correspond to openings in the case and panel to receive retainer devices. O-rings may be disposed on the retainer devices between rails/corner pieces and sides of the case.
