  • Publication number: 20230354759
    Abstract: A system and method for growing plants by reducing the need for additional water. The hydroponic plant growth system utilizes a reservoir to collect excess water from the support tubes or feeder tubes and refeed the water to the plants through the pump. The water fed to the plants is mixed with nutrient enriched air which is sent directly to the plant roots through the inlets along with the water. This helps the plant absorb the required nutrients and the availability of nutrients is maintained as the water is pumped by the reservoir continuously in this closed loop system.

  • Patent number: 9997901
    Abstract: A method of automatically cutting off high temperature and high current, includes calculating an FET voltage applied to an FET (Field Effect Transistor), based on a resistance of a CTS (Critical Temperature Switch) and a reference resistance, comparing the FET voltage with a predetermined threshold voltage, and setting the FET to an ON state when the FET voltage is higher than the threshold voltage and setting the FET to an OFF state when the FET voltage is lower than the threshold voltage. The CTS is a switch including an MIT (Metal-Insulator Transition) device. The MIT device has a metallic property only in a predetermined temperature range.

  • Publication number: 20170265408
    Abstract: A modular hydroponic growth system is presented which supports a variety of plant growth with flexible conditions. The modularity is supported in part by quick-connect systems which allow liquids and air to be brought to and from subunits in an efficient manner. An advanced HVAC system allows for fresh air to be brought down one wall and stale air to be extracted from an opposing wall. The system allows for automation through the use of intelligent trolleys.

  • Publication number: 20050213575
    Abstract: A method for preventing a transmission delay of data packets transmitted through an uplink due to a transmission gap (TG) period occurring when a user equipment (UE) performs handover from a Node B to its neighbor Node B in a mobile communication system. In the method, the Node B sequentially transmits data packets to the UE through a plurality of subframes, and the UE transmits response signals for the data packets transmission-delayed for the TG period to the Node B through a subframe of an uplink dedicated physical control channel (DPCCH), following the TG period.
