摘要: A control method of a work machine in which a rotation number of a fan that takes outside air into an engine room accommodating an engine varies with a rotation number of the engine, includes: executing first control of regenerating a collecting filter unit that collects particulates contained in exhaust gas of the engine by a temperature rise of the exhaust gas; when the work machine is changed from a steady state to a specific state, executing second control of decreasing an amount of working oil discharged from a hydraulic pump by driving of the engine; and, when the first control and the second control are concurrently executed, executing third control of increasing the rotation number of the engine.

摘要: Control circuitry feeds a command current to a hydraulic pump whose displacement increases in accordance with increase in the command current. The displacement of the hydraulic pump is a delivery amount per rotation of the hydraulic pump. The control circuitry receives an input of actual measurement data, the data either indicating an actual relationship between the command current and the displacement of the hydraulic pump or indicating a predetermined rotation speed and an actual relationship between the command current and a delivery flow rate of the hydraulic pump at the predetermined rotation speed; and receives an input of a minimum-use displacement of the hydraulic pump or a minimum-use delivery flow rate of the hydraulic pump at a reference rotation speed. The control circuitry determines a minimum-use electric current by using the actual measurement data, the minimum-use electric current corresponding to the minimum-use displacement or the minimum-use delivery flow rate.

摘要: The present disclosure describes a hydraulic control system for power loss prevention that includes at least one controller having a memory and a processor. The at least one controller is configured to determine an observed flow rate of hydraulic fluid at a hydraulic actuator based on an actuation speed of the hydraulic actuator. Additionally, the at least one controller may compare the observed flow rate to a commanded flow rate of the hydraulic fluid to the hydraulic actuator by a hydraulic pump of the hydraulic control system. Further, the at least one controller may adjust the commanded flow rate to a target flow rate in response to determining that a difference between the commanded flow rate and the observed flow rate is greater than a threshold value.

摘要: A method for execution by a computing entity includes interpreting an electric response from a set of electric field sensors to produce a piston velocity and a piston position of a piston associated with a head unit device. The head unit device includes a chamber filled with a shear thickening fluid (STF) that includes a multitude of piezoelectric nanoparticles. The method further includes determining a shear force based on the piston velocity and the piston position. The method further includes determining a desired response for the STF based on the shear force, the piston velocity, and the piston position. The method further includes generating an electric activation based on the desired response for the STF and outputting the electric activation to a set of electric field emitters positioned proximal to the chamber.

摘要: A pneumatic delivery system is used to facilitate delivery of canisters comprising delivery payloads by unmanned systems, such as unmanned aerial vehicles (UAVs). The pneumatic delivery system comprises a tube having a channel within a tube wall, where a canister is configured to move through the tube. The tube comprises a tube opening and a transfer mechanism proximate the tube opening. The transfer mechanism engages a canister having a payload that is moved within the tube. The transfer mechanism moves the canister through the tube opening by extending from a first transfer position to a second transfer position. At the second transfer position, the transfer mechanism orients the tube and releases it to a UAV for delivery.

摘要: State of art techniques utilize active systems for stronger suction in surface crawlers while the passive approaches have limitation in providing consistent grip while moving across curved surfaces or dents. Embodiments herein provide an autonomous surface crawling robot for crawling over surfaces using electro-mechanical assembly for creating strong suction force and enabling the robot to smoothly crawl over flat surfaces, horizontal/vertical/inclined surfaces, curved surfaces, and surfaces with dents. Battery powered motors are used for only mobilization, while mechanical assembly generates suction to provide consistent grip across different type of surfaces. A dual flexible cam profile assembly including a cam profile and a guide rail generates required suction and addresses the technical challenge of maintaining suction across varying surfaces without using external power for suction generation. The dual flexible cam profile provides a robust, less prone to error or slippage type passive crawler mechanism, with consistent grip across uneven the surface.

摘要: A pneumatic actuator and control valve assembly has a housing with a control cavity for a control valve and an actuator cavity for an actuator piston and rod assembly. The control cavity and actuator cavity both have an elongated shape and are substantially parallel to each other. The control cavity has a supply port and first and second control valve outlet ports and at least one vent port with the control valve being movable through the control cavity for controlling communication between the supply port and the first and second outlet ports. The actuator cavity has first and second ports at the retracted and extended ends for shuttling the piston and within the actuator cavity between a retracted and extended end position. The housing has a first inlet and second inlet for passage of pressurized fluid to and from the housing.

摘要: A method for using a tool to extract tent stakes from the ground is disclosed. The tool has a portion that houses the motor and hydraulic fluid tank, and a hydraulic cylinder portion the user holds against a tent stake and operates to pull the tent stake. Hydraulic hoses connect the two portions. Separating the motor from the hydraulic cylinder allows the user to manipulate just the portion performing work on the tent stake without having to also lift or stabilize the larger and heavier motor portion. Rotating a handle causes the hydraulic cylinder to extend or retract. A hand guard may be present to prevent accidental crush injuries. The tool is designed to fully extract a stake in two strokes of the hydraulic cylinder.

摘要: An irrigation management system is disclosed and positionable in-line with an irrigation pipe for monitoring and controlling a flow of fluid therethrough. In at least one embodiment, the system provides an inlet pipe and an opposing outlet pipe in serial fluid communication with the irrigation pipe. At least one fluid control valve is in serial fluid communication between the inlet pipe and outlet pipe for selectively controlling the flow of fluid therebetween. The fluid control valve provides a main valve and a hydraulic actuator for selectively moving the main valve between open and closed positions. The hydraulic actuator is also in serial fluid communication between a pair of actuator valves for moving the hydraulic actuator between open and closed positions. The system also provides at least one sample collection tank configured for temporarily storing a volume of fluid diverted from the irrigation pipe in order to be tested.
