A new and distinct variety of landscape shrub rose plant is provided which abundantly forms on a substantially continuous basis attractive single medium pink blossoms that change to light pink upon maturity. To embed a reference measurement into the target measurement, the directional coupling means include a four-port circulator with an additional port arranged between a port receiving the transmit pulses and a port coupled to the antenna. The electrodes are then floated to reduce the voltage applied into a discharge space during the discharge to cause a self-quenching of the discharge, thereby precisely controlling wall charges. Thus, the fuel economy of the vehicle can be increased.
