The present invention relates to a sensor for humidity, etc. which has high precision, very small electrical power consumption and simplified composition, and a management system therefor. The sensor and the management system therefor according to the present invention are also economical. The sensor according to the present invention comprises two electrode pads and an absorption layer for absorbing moisture, etc. between them, and detects a capacitance variation and a resistance variation between the electrode pads, measuring humidity, etc. in real time. In the sensor, one or both of the electrode pads can be made by printing or coating a conductive material on a paper pad or a fabric pad in a mesh shape of fine lines. Or the electrode pads can be fabrics with fine thread of a mesh-type electric conductor coated by an absorptive material having an insulating property.

An improved fuel processor for fuel cells is provided whereby the startup time of the processor is less than sixty seconds and can be as low as 30 seconds, if not less. A rapid startup time is achieved by either igniting or allowing a small mixture of air and fuel to react over and warm up the catalyst of an autothermal reformer (ATR). The ATR then produces combustible gases to be subsequently oxidized on and simultaneously warm up water-gas shift zone catalysts. After normal operating temperature has been achieved, the proportion of air included with the fuel is greatly diminished.

A first inert gas (5) is supplied into a reaction space (1) and a high-frequency power supply (4) applies a high-frequency electric field so that a primary plasma (6) composed of the first inert gas which has been made into the plasma is ejected from the reaction space. A mixed gas area (10) in which a mixed gas (8) having a second inert gas (12) as a main ingredient and a proper amount of a reactive gas (13) mixed is formed. The primary plasma collides into the mixed gas area to generate a secondary plasma (11) composed of the mixed gas which has been made into the plasma, and the secondary plasma is sprayed on a processed object (S) to carry out a plasma processing. Accordingly, the plasma processing is carried out in a wide range by an atmospheric pressure plasma generated by a small input power.

Systems are disclosed that utilize electrical signals from detectors of an imaging focal plane array or antenna elements of an antenna array to modulate optical signals. Antenna or focal plane array elements are coupled to optical waveguides by way of whispering gallery mode resonators made of electro-optic material. The resonators modulate optical signals in the waveguides based on the electrical signals from the detectors / antenna elements. The signals received by the array are converted into the optical domain, allowing subsequent optical processing and / or distribution. Each detector / antenna element involved can be identified by the specific wavelength and waveguide through which its signal is coupled, enabling subsequent optical processing of the signals such as by wavelength division multiplexing systems. Additionally disclosed are imaging sensor photonic systems that include WDM components and other optical components such one or more optical narrow-band amplifiers and / or filters. Related electro-optic modulation and tuning methods are also described.
