Abstract: A method and apparatus for measuring a pressure. A pressure gauge includes a first plate having a resonant frequency related to a pressure at the pressure gauge. The first plate is thermally-excited at a selected frequency, and a sensor measures a first power level of a first light having a first wavelength reflected from the first plate and a second power level of a second light having a second wavelength reflected from the first plate.

Abstract: A panhandle cover made of a heat-resistant material including leather is generally of a longitudinally-split tubular configuration with its longitudinal split having the converging flanks overlapping one inside the other. The nature of genuine leather enables the flanks to conform to any pan-handle as it wraps around the handle. The flexibility of the leather cover adapts to the handle with conformity to the handle-configuration through use.
