  • OPTICAL DIODE LASER TOUCH-CONTROL DEVICE
    Publication number: 20100045634
    Abstract: An optical diode laser touch-control device includes two light emitters and a plurality of receivers around a touch-acting area of a touch panel. The light emitters are disposed on two adjacent corners of the touch panel in the touch-acting area, and each employs a diode laser to continuously project a diffused light through a lens for covering the touch-acting area to form an interlaced touch screen. The receivers, which are capable of receiving the diffused light, are disposed on the touch panel around the touch-acting area to receive the diffused light. As a finger touches the touch-acting area of the touch panel, a part of the diffused light is blocked from being projected onto the receivers, and the touch position of the touch-acting area may be calculated accordingly.

  • METHOD OF CONVERSION OF SYNGAS USING MICROORGANISM ON HYDROPHILIC MEMBRANE
    Publication number: 20100047886
    Abstract: A stable system for producing liquid products such as ethanol, butanol and other chemicals from syngas components contacts CO or a mixture of CO2 and H2 with a hydrophilic membrane under anaerobic conditions and transfers these components into contact with microorganisms contained as a biofilm on the membrane. Maintaining the microorganisms as a biolayer on the surface of the membrane facilitates cleaning of the membrane surface that retains the biofilm. In addition the shell gas space that surrounds the membranes may be flooded to reduce or remove the biofilm. Agitation of the liquid, by for example the bubbling of gas in the surrounding shell space, can fully or partially remove the biofilm from the membrane.
