An electronic system generally includes a flatwire electronic site and a flatwire bus electronically connecting the flatwire electronic site to an electronic device in the engine compartment. A semiconductor substrate comprising a lattice-strain relaxed silicon germanium layer, a silicon germanium layer, and a lattice strained silicon layer formed in this order of mention onto a silicon substrate is used, while trenches are formed in the portions for device isolation regions of the semiconductor substrate by etching. The method includes the steps of: opening the spigot, thereby dispensing a liquid through the spigot of the wheeled receptacle and onto the surface; and guiding the wheeled receptacle across the surface via the steering handle, thereby dispensing the liquid through the spigot of the wheeled receptacle onto a selected area of the surface. A sensor is provided within the handheld device that detects the attitude of the device as held by the user. The relief zone may be radially outward from the sealing portion.
