A method and apparatus for extracting power in a switch location, and in a load location for use in a pre-existing infrastructure of switching AC power to a lamp (or other load) via a two terminal switch device. The switch is replaced with a module including a first controlled switch (such as a triac or relay) and a first impedance (such as a capacitor) connected in parallel, and another module including a second controlled switch (such as a triac or relay) and a second impedance (such as a capacitor) connected in parallel, is installed at the load location. In an off state where the two controlled switches are in open state, current is flowing via the impedances, but not through the load, so that power extractor circuits in the modules, connected in series to the impedances, extract low power for DC powering logic and other loads in the modules.

A plant cultivation device includes a plurality of boxes, a connection unit, and an end section unit. Each box is provided in an inner space thereof with a cultivation chamber and a light source housing chamber. The plurality of boxes are arranged in a line. The connection unit mutually connects two adjacent boxes. The end section unit is mounted to an end section of a box which is arranged in an end of the line. The end section of the box is unconnected to the connection unit. Each box includes a ventilation opening for ventilating the cultivation chamber, and a ventilation port for air cooling the light source housing chamber. Each of the connection unit and the end section unit includes a first ventilation passage through which air flows into the ventilation opening, and a second ventilation passage through which air flows into the ventilation port.

A plant growth system and medium employs a manmade mineral fiber-based growth medium that includes from about 40% to about 99.5% man-made mineral fiber interspersed with from about 0.5% to about 60% by weight pieces of natural or synthetic open cell foam. The foam includes from about 5 to about 50 pores per square inch. Additives in the form of nutrients, fungi, and bacteria are included. Water is supplied to plants by flood and drain watering during plant growth in the medium. EC is maintained within a range of about 0.5 mS/cm to about 2.500 mS/cm and pH is maintained within a range of about 5.6 to about 5.8.

Methods and systems for automated plant production including a primary control hub including a controller, a plurality of plant growth modules, each plant growth module including a secondary hub in communication with and controlled by the primary hub, a plurality of plant assemblies for growing a plurality of individual plants, and a distribution tank in fluid connection with each of the plant assemblies, a plurality of supply tanks containing a supply to support plant growth and a plurality of supply lines, each supply line connecting one supply tank to the distribution tank of each of the plurality of plant growth modules. The primary hub separately controls delivery of each of the supplies to each of the plurality of plant growth modules.

A hydroponic container growing system is provided. The growing system provides a closed growing environment providing climate and other growing conditions suitable for year-round plant production. The growing system may include a container having a plurality of subsystems therein. The plurality of subsystems may include a plant production system, an environmental regulation system, an energy capture system, a control system, and a dosage system. The plant production system may include an Ebb and Flow irrigation system and one or more Nutrient Film Technique (NFT) irrigation systems. A single reservoir may supply the Ebb and Flow irrigation system and a NFT irrigation system to provide a dual technique, single nutrient supply source irrigation system for plant production. An energy capture system which utilizes the kinetic energy of flowing liquid to generate electrical energy may be integrated into one or more irrigation systems within the plant production system.

Methods are proposed to define UE behavior for performing synchronization signal block (SSB) based radio link monitoring (RLM) and channel state information reference signal (CSI-RS) based RLM. In a first novel aspect, if CSI-RS based RLM-RS is not QCLed to any CORESET, then UE determines that CSI-RS RLM configuration is error and does not perform RLM accordingly. In a second novel aspect, SSB for RLM and RLM CSI-RS resources are configured with different numerologies. UE perform SSB based RLM and CSI-RS based RLM based on whether the SSB and CSI-RS resources are TDMed configured by the network. In a third novel aspect, when multiple SMTC configurations are configured to UE, UE determines an SMTC period and whether SMTC and RLM-RS are overlapped for the purpose of RLM evaluation period determination.

A closed recirculating aquaponics system combined with a biofloc tank for symbiotic breeding of aquatic species and plant species, wherein the culture water for growing aquatic species is transferred to a plant growing apparatus, organic material in the culture water is used as nutrients for plant species and the water is purified in the plant growing apparatus, and purified water is reused as culture water for aquatic species to facilitate symbiotic breeding of aquatic species and plant species without any need of culture water exchange, reducing cost for production and enhancing production efficiency.
