The protection device may further include a foreign object detection unit configured to detect a foreign object, and discharge the content from the nozzle in response to the foreign object detection unit detecting the foreign object.

Systems and methods are disclosed that include a spraying apparatus having a hand held spraying device, a flexible reservoir connected in fluid communication with the hand held spraying device and worn on the body of a user of the spraying apparatus, and a pressure device that provides pressure to the flexible reservoir to move fluid from the flexible reservoir to the hand held spraying device.

In one embodiment, a remote monitoring system for a fluid applicator system is disclosed. The fluid applicator system is disposed to heat and pump spray fluid, and to transmit reports including sensed temperatures, pressures, and other operational parameters of the fluid applicator system via a wireless network. The remote monitoring system comprises a data storage server, and an end user interface. The data storage server is configured to receive and archive the reports. The end user interface is configured to provide a graphical user interface based on the reports. The graphical user interface illustrates a status of the fluid handling system, sensed and commanded temperatures of the fluid handling system, sensed and commanded pressures of the fluid handling system, and usage statistics of the fluid handling system.

A method for applying a coating product using the drop on demand technology, wherein the coating product is deposited by a robot applicator including a controller and at least one nozzle with sequential opening, commanded by the controller, the method including moving the nozzle of the robot applicator between a starting point and an arrival point, the projections of which, along the ejection axis of the nozzle, on the surface to be coated, define first and second reference points respectively belonging to two edges of the surface to be coated, in order to deposit a series of drops between the two edges, the spacing between the respective centers of two successive drops being adjusted by the controller as a function of the length of the journey between the two reference points and such that the last drop is deposited in a centered manner on the second reference point.

Various embodiments of a spray measurement system having a jig device that allows measuring spray output of one or more spray nozzles and determine spray distribution patterns of the spray nozzles are disclosed.

The present disclosure provides systems and methods for managing a temperature of a battery energy storage system (“BESS”). A method may comprise identifying operating temperature limitations of the BESS; obtaining a forecast horizon comprising a forecast of external environmental conditions for a time period; identifying a charging/discharging schedule of the BESS; simulating operation of the BESS for the time period for each of a plurality of sequences of thermal management modes according to the charging/discharging schedule and the forecast horizon, the simulating generating an energy consumption and an operating temperature forecast of for each of the plurality of sequences of thermal management modes; selecting a sequence of thermal management modes of the plurality of sequences; and operating the equipment according to the selected sequence of thermal management modes.

Examples provide a system for watering plants on a rack. Sensor data is analyzed to generate a status of a plant on a rack and updated water instructions are generated. A robotic device moves the selected plant rack to a watering zone. A release of water onto the selected plant rack within the watering zone is detected and a set of rotational maneuvers is initiated to enable equal water distribution across the selected plant rack. The selected plant rack is then return to the original, assigned location based on a cessation of water emissions being detected.

A dispenser includes: a plunger; a dispensing portion configured to dispense and suction liquid in response to an advance and a retraction of a distal end surface of the plunger along an axial line. The dispensing portion includes: a surrounding portion surrounding the distal end surface of the plunger about the axial line to define an accommodation chamber for accommodate the liquid to be dispensed; and an end portion facing the distal end surface of the plunger. The surrounding portion includes an inlet opening into the accommodation chamber to receive the liquid into the accommodation chamber. A distance from the inlet to the end portion is less than or equal to half of a maximum stroke of the distal end surface of the plunger.

A mist blower in one aspect of the present disclosure includes an air blower, an air feed pipe, a tank, a liquid feed pipe, a nozzle, a first electromagnetic valve, a controller, and a first manual switch. The first electromagnetic valve (i) opens the liquid feed pipe in response to the first electromagnetic valve being activated and (ii) closes the liquid feed pipe in response to the first electromagnetic valve being deactivated. The controller activates or deactivates the air blower and the first electromagnetic valve. The first manual switch (i) is manually moved by a user of the mist blower and (ii) commands the controller to activate or deactivate the air blower based on a movement of the first manual switch.

Proposed are a chemical liquid supply unit, a substrate processing apparatus having the same, and a chemical liquid supply method. More particularly, proposed is a technique for supplying chemical liquids of different flow rates, in which a chemical liquid is supplied at the same flow rate to each of a plurality of chemical liquid lines and the flow rate of the chemical liquid is adjusted through a flow control valve disposed on at least one chemical liquid line selected among the plurality of chemical liquid lines, so that the plurality of chemical liquid lines can supply chemical liquids at different flow rates.
