A new and distinct Rhododendron cultivar named \u2018HOMLEE\u2019 is disclosed, characterized by distinctive fuchsia pink, semi-double flowers. A sleeve is cast in such a manner that it is embedded in a cylinder block with a space from a deck face simultaneously with the molding of the opening end portion of a cylinder bore and recesses in the cylinder block in the space with a bore pin mated with a sleeve. When a drive mode of the galvanometric scanner system is changed, the scanner driver can accordingly be optimized readily and quickly. The embodiments are applicable to terrain mapping, bathymetry, seismology, detecting faults, biomass measurement, wind speed measurement, temperature calculation, traffic speed measurement, military target identification, surface to air rangefinding, high definition survey, close range photogrammetry, atmospheric composition, meteorology, distance measurement, as well as many other applications. The zig-zag resilient stent can be a compression stent.
