    Publication number: 20140168456
    Abstract: A light source sensing device and a light source sensing method thereof are provided. The light source sensing device includes an optical sensor, a rod, a motor and a controller. The optical sensor is used for sensing lighting brightness emitted by the light source. The rod is disposed on a circular track which surrounds the optical sensor. When the light source irradiates the rod, a shadow is formed on a sensing surface of the optical sensor. The motor drives the rod to move along the circular track in a moving speed. The controller is coupled to the motor and the optical sensor, and controls the optical sensor to sample in a sampling frequency during a sampling period for obtaining a plurality of brightness values. The controller calculates and processes the brightness values for obtaining an irradiating angle of the light source.

The films are continuous, preventing absorption of species within the converter on the catalyst support. The converters provide higher oxidation efficiency than conventional catalytic converters, in certain embodiments approaching the stoichiometric ratio for the reaction. The converters also provide minimal loss of chemical species within the converter. Also provided are novel methods of fabricating catalytic converters that involve atomic layer deposition of Pt or other catalyst on the support, as well as methods and devices for sensing NO in samples that involve catalytic conversion of NO to NO2.
