A method for thinning a material surface using an instrument means for moving an article with a discontinuous surface with an abrasive material dispersed between the material surface and the discontinuous surface where the discontinuous surface of the moving article provides an efficient means for maintaining contact of the abrasive with the material surface. The TCSAW device may include a pyroelectric substrate, a plurality of electrodes formed on a first surface of the pyroelectric substrate, an amorphous silicon layer formed over the plurality of electrodes, and a temperature compensating layer formed over the amorphous silicon layer. The on-board module causes a telematic device on the vehicle to broadcast a message including a problem code that identifies the problem the vehicle is having. The clamp can comprise a third arm projecting therefrom to prevent complete cycling of the firearm action. The air cleaner arranged on the side of the two banks is supported by cleaner supporting units integrally provided in the cylinder blocks or the cylinder heads in the two banks.
