Disclosed is a method for calculating instantaneous sprinkler strength comprising: ensuring that a translational sprinkler (1) maintains a stable operating state, placing b rain barrels (3) at a distance of a metres from the translational sprinkler (1), and moving the translational sprinkler (1) to obtain measurement data; calculating movement time, and the average sprayed water depth received by the rain barrels (3); assuming the distribution form of the amount of water of the translational sprinkler (1), establishing a function relationship between an instantaneous sprinkler strength ht and the movement time t, and calculating a variable in the function relationship; and substituting into the established function relationship a specific numerical value of an instantaneous point in time t of the movement of the translational sprinkler (1), so that the value of ht obtained is a numerical value of the instantaneous sprinkler strength of the translational sprinkler (1). The calculation method has a simple operation, is fast and can obtain a precise calculation result with relatively low experiment costs.

A method for automatic glue-spraying of stringers and inspection of glue-spraying quality based on measured data. Three-dimensional (3D) point cloud data of a stringer-skin assembly is collected by 3D laser scanner, and then processed by denoising and sampling. Feature points of an intersection line of a site to be glued of the stringer-skin assembly are extracted by K-means clustering method based on Gaussian mapping, and a minimum spanning tree is constructed based on a set of the extracted feature points. A connected region is established to obtain an initial feature intersection line of the string-skin assembly, which is optimized by random sample consensus algorithm to remove redundant small branch structures to obtain the actual glue-spraying trajectory. The quality of the glue sprayed on the stringer-skin assembly is inspected by line laser to determine positions of the defects, which are then subjected to secondary glue-spraying.

A dry burning detection method, applied to a vaporizer, includes: obtaining vaporization parameters of a vaporization piece in real time, and calculating a variance between the vaporization parameters and a sample mean, the sample mean being a value representing a vaporization parameter level of a stable vaporization stage of the vaporizer; and determining that the vaporization piece is dry-burned if the variance is greater than a preset variance value corresponding to the vaporization parameter, the preset variance value being used for distinguishing a vaporization parameter fluctuation caused by vaporization dry burning and a vaporization parameter fluctuation caused by non-vaporization dry burning.

A device comprising means for patching an area. The patching means comprises means for sealing the perimeter of the patching means to an object or surface to create an air-tight sealed area between the patching means and the object or surface. The device further comprises means for dispensing a substance into the sealed area and means for providing a liftable portion on the patching means. The liftable portion of the patching means comprises means for resealing the liftable area to the patching means. The device may further comprise means for providing a middle compartment configured to hold a substance.

The invention relates to a device and method for applying a spraying means using a portable spraying device.

An automated system for identifying a watering zone malfunction includes a sensor and a controller. The watering zone includes a valve that couples an input conduit to an output conduit. The output conduit terminates at one or more water distributors. The sensor is for capturing mechanical perturbations of the watering zone. The controller is configured to: store a profile defining at least one profile parameter based upon a transient operation of the zone in an intact state, receive the signal from the sensor during a watering operation when the zone is in an unknown state, compute a operation parameter based upon the signal for at least one time window of receiving the signal, determining a malfunction exists, and determine whether to take further action based upon the comparison.

A device for distributing bulk material, such as seed material, includes a flow path having at least one conduit for conveying the bulk material from a bulk material source towards an agricultural area, and a blockage detection device in the flow path. The blockage detection device includes at least one sensor, which is mounted to the outside of the line and is configured to register mechanical vibrations of the line, as well as an evaluation unit in signal communication with the sensor, which is configured to detect a blockage as a function of the registered mechanical vibration. A method for detecting a blockage includes a sensor that identifies blockage as a function of the detected mechanical vibration.

Examples provide a system for watering plants on a rack. A robotic device attaches to a portion of the rack and pulls or pushes the rack to a watering zone. A sprinkler device sprays water to evenly distribute water across all plants on the rack. The system determines quantity of water, duration of watering, and frequency of watering based on real-time sensor data and context data associated with the environment, historical watering data, condition of the plants on the rack and a set of customized maintenance rules based on the type of plants on the rack. When watering is complete, the robotic device returns the rack to a designated location and detaches from the rack. The robotic device then attaches to another rack having plants on it scheduled for watering. The watering schedule is updated dynamically based on changing weather and plant state.

The disclosure relates to a device that saves water, energy, and money and may record the savings with a software analytics dashboard. The device allows cold water to flow out when the shower is first turned on and slows or shuts water flow once the water is heated and the shower is unoccupied. After the presence of the user is detected, the shower flow may resume.

An electrostatic sprayer system for dispensing and dispersing a liquid containing a spray compound includes a spray cloud dispersal feature that reduces the time that a residual spray cloud containing droplets including the spray compound remains suspended after spraying. A method of dispersing the residual spray cloud is implemented by a control system that causes a flow control system to deliver a non-active gas or liquid in conjunction with stopping delivery of the liquid containing the spray agent and charged with the same polarity, so that a charged cloud of the non-active gas or liquid, which may be air, displaces the suspended active fluid particles. The non-active gas or liquid may be dispensed for a predetermined time interval as determined by the control system, or the operator may control the time interval during which that the non-active fluid is dispensed.
