The present invention provides a method and apparatus for enhancing webpage browsing. , and is deformed towards a cold tool contour by the action of a non-oxidizing gaseous pressure medium introduced into the tool and heated to the hot-forming temperature, as well as by underpressure generated on the side of the workpiece facing away from the pressure medium. A determination is made in response to the first signal and the second signal, whether the health-care worker is absent from being near the patient. In use, the substantially planar members contact the rear and outside edge of a frame for a canvas. In the method, at least the high-frequency power having a frequency f1 and the high-frequency power having a frequency f2 are used and satisfy the following two conditions as the high-frequency powers:. The method may include varying a data transmission rate value based on a difference between a received signal strength and a receiver sensitivity value and reducing the transmission power level when transmission is at the highest data transmission rate.
