Abstract: Apparatus for heating the outer surface of an object such as a loaf of bread. The object is conveyed through a heating chamber which has a plurality of apertures therein. A plurality of laser beams of a wavelength that is readily absorbed by the outer surface of the object are generated and each beam is directed through a respective aperture in the chamber. Each beam entering the chamber is diverged to scatter the beam and spread the energy contained therein out over a wider area than that in which the energy is initially contained. The divergent beams are directed into a predetermined zone within the chamber through which the object must pass and the laser radiation within the zone strikes the outer surface of the object and is absorbed thereby to heat the outer surface.

Abstract: Apparatus for detecting wet and icy conditions on the surface of a pathway. A block of electrically insulative material is embedded in a pathway with the top surface of the block being substantially flush with the surface of the pathway and exposed to atmospheric precipitation. A sensor electrode is positioned a predetermined distance beneath the top surface of the block and encapsulated in the block so that the accumulation of atmospheric precipitation on the top surface of the block affects the capacitance and conductance between the sensor electrode and the pathway. A time-varying electrical current having an amplitude which is substantially constant and independent of the accumulation of atmospheric precipitation on the top surface of the block is supplied to the sensor electrode. The apparatus also includes an amplifier for amplifying an electrical signal applied to a pair of input terminals thereof.
