  • Patent number: 8241634
    Abstract: Disclosed herein is a carbon supply device for supplying carbon dioxide during large scale cultivation of micro-algae in open pond, and its application method and use. The device comprises a trap container in which a partition plate is installed vertically and has a 10-50 cm gap from the container bottom, and the partition plate is higher than the wall of the trap container; and a gas distributor is positioned at the bottom of the container. In use, the trap carbon supply device is embedded in bottom of an open pond, wherein the partition plate is above the liquid level of the culture solution in the open pond such that the culture solution driven by a stirrer flows into the trap carbon supply device from one side thereof, and flows out of the device from the other side thereof, wherein the culture solution is mixed with carbon dioxide at the bottom of the container.

  • Publication number: 20110267170
    Abstract: A method for processing signals received by a wireless controlled circuit of a steam device, includes the steps of: judging a received signal is a registration signal or a control signal; if the received signal is a registration signal, storing an ID code contained in the registration signal; and if the received signal is a control signal, judging whether the control signal contains an ID code same as a stored ID code or not, then responding a control instruction contained in the control signal if yes, and not responding the control instruction contained in the control signal if no. The present invention has the following advantages: when a plurality of the steam devices are placed together, each wireless controlled circuit of the steam devices will only respond the special remote controller which is registered correspondingly and not respond a non-corresponding remote controller.
