Abstract: A device of deodorizing and minimizing VOC in exhaust gas with photocatalyst is equipped with UV lamp wrapped with photocatalyst coating fiberglass sleeve, disposed in an exhaust gas treatment chamber. At an inlet end, exhaust gas passes an activated carbon honeycomb plate which adsorbs VOC gas of the exhaust gas. The photocatalyst-based exhaust gas treatment chamber is installed in a manner to face the sun. Sunlight falls on the exhaust gas treatment chamber, thus causes the activated carbon honeycomb plate to release the otherwise adsorbed VOC gas. After that, undergoing photocatalyst-based exhaust-gas-borne VOC treatment system, the released VOC gas is oxidized and discharged without odorous.

An example method for creating a handwritten character font library can include receiving a set of standard characters to a computing device, and deriving a group of character components from the initial set of characters. A subset of characters is selected from the set of standard characters, the subset collectively including substantially all the group of character components. Handwritten characters corresponding to the subset of characters are received to the computing device, and handwritten character components are extracted from the hand written characters corresponding to the group of character components. A set of handwritten characters is then constructed from the received handwritten characters and/or the handwritten character components.
