Abstract: A spin-through drive rod centralizer consisting of a stator constructed of plastic, or other appropriate material, which is mounted on a rotor attached to the body of the drive rod, which provides the bearing surface for rotation of the rotor within the stator. The stator is equipped with multiple vanes which extend to the full internal diameter of the production tubing. In one configuration, the radially oriented vanes have cut-outs which allow the tip of the vane to compress inward, allowing passage through tight spots in the tubing, then rebounding to the full ID of the tubing. In another configuration, the vanes are tangentially attached to the stator body, such that they bend in a circumferential direction to allow passage through tubing tight spots, then rebound to full tubing ID.

Abstract: Systems and methods are provided herein for encoding and storing information in nucleic acids. Encoded information is partitioned and stored in nucleic acids having native key-value pairs that allow for storage of metadata or other data objects. Computation on the encoded information is performed by chemical implementation of if-then-else operations. Numerical data is stored in nucleic acids by producing samples having nucleic acid sequences copy counts corresponding to the numerical data. Data objects of a dataset are encoded by partitioning of bytes into parts and encoding of parts along distinct libraries of nucleic acids. These libraries can be used as inputs for computation on the dataset.

Abstract: Inputs from sensors (e.g., image and environmental sensors) are used for real-time optimization of plant growth in indoor farms by adjusting the light provided to the plants and other environmental factors. The sensors use wireless connectivity to create an Internet of Things network. The optimization is determined using machine-learning analysis and image recognition of the plants being grown. Once a machine-learning model has been generated and/or trained in the cloud, the model is deployed to an edge device located at the indoor farm to overcome connectivity issues between the sensors and the cloud. Plants in an indoor farm are continuously monitored and the light energy intensity and spectral output are automatically adjusted to optimal levels at optimal times to create better crops. The methods and systems are self-regulating in that light controls the plant's growth, and the plant's growth in-turn controls the spectral output and intensity of the light.

Abstract: Aspects of a storage device including a controller, a calibration resistor and a die having an output driver and a calibration circuit are provided, which allow for an output impedance of the output driver to be calibrated to a lower impedance than a minimum required for reading data across PVT variations of the die at maximum loading of the controller. To check whether slow corners may operate using the lower impedance, the controller determines whether the output impedance of the output driver can be calibrated to the lower impedance at a maximum temperature and minimum voltage applied to the die, or whether a calibration code generated from the calibration circuit exceeds a threshold at a nominal temperature and voltage applied to the die. Thus, slow corners are screened out from lower impedance use, while faster devices are designed with a smaller calibration resistance to benefit from increased memory and speed.

Abstract: Sensor data from load cells at a shelf is processed using a first time window to produce first event data describing coarse and sub-events. Location data is determined that indicates where on the shelf weight changes occurred at particular times. Hypotheses are generated using information about where items are stowed, weights of those of items, type of event, and the location data. If confidence values of these hypotheses are below a threshold value, second event data is determined by merging adjacent sub-events. This second event data is then used to determine second hypotheses which are then assessed. A hypothesis with a high confidence value is used to generate interaction data indicative of picks or places of particular quantities of particular types of items from the shelf.
