Abstract: A device for use with soft robotic devices comprises soft fluidic actuators, a microfluidic/minifluidic valves and channels module, a fluidic module, sensors, and a control module. The actuators are operable to apply predetermined effects to surfaces and/or objects. The microfluidic/minifluidic valves and channels module has micro/mini fluidic channels and on-chip fluidic pressure-controlled pinch valves forming a fluidic network. Each pinch valve has a valve pinch chamber, a membrane layer, and a valve control pressure chamber. The control module receives signals from the sensors and controls the fluidic module to control the pinch valves to induce flow of fluid under pressure to the actuators. An active compression apparel may include the device, and may have a skin contact backing layer and a strain-limiting backing layer sandwiching the actuators which are operable to provide compression to the skin and/or limb of a user through the at least one backing layer.

Abstract: The invention discloses an energy storage transient power coordinated control method for restraining subsequent commutation failures, which includes: detecting DC current, AC bus voltage and arc quenching angle on the inverter side; Controlling the energy storage power station to enter the transient control mode when the DC current is greater than the first current threshold or the AC bus voltage is less than the voltage threshold or the arc quenching angle is less than the first arc quenching angle threshold. By detecting the DC current and arc quenching angle on the inverter side, the active power output time instruction and reactive power output time instruction are determined respectively. The active power output amplitude instruction is determined by detecting the AC bus voltage, and the reactive power output amplitude instruction is determined by using the constraint of the total energy storage capacity.

Abstract: Air microfluidics and minifluidics enabled active compression apparel enhances mobility and quality of life for individuals by minimizing risks of injuries, enhancing rehabilitation, and maximizing comfort. Balloon actuators, integrated with a garment, provide active compression and augmenting forces to anatomical portions of the human body. The balloon actuators are actuated by fluidic pressurization hardware. The air microfluidics and minifluidics system miniaturizes fluidic pressurization hardware and makes it wearable, ultra lightweight, and ultra formfitting. The air microfluidics and minifluidics system includes micro and mini channels of various lengths, cross-sectional areas, and functions via principles of equivalent hydraulic resistance allowing for fluidic transportation, passive delay in pressurization of the balloon actuators, and digital soft fluidic actuation where the compression force is based on the number of inflated balloon actuators instead of their pressure.

Abstract: A separative high-pressure cooling and lubrication method is provided. The method includes: S1: apply ultrasonic vibration on the cutting tool on a machine tool; S2: deliver high-pressure cutting fluid to a jet nozzle so as to spray the high-pressure cutting fluid to the cutting zone of the ongoing process. The method also includes: S3: set cutting parameters and ultrasonic vibration parameters to adjust the separation amount ? between the cutting tool and workpiece, and adjust the pressure of the high-pressure cutting fluid; S4: when the cutting tool and the workpiece separate completely with each other periodically, the high-pressure cutting fluid enters and flows through the interior of cutting zone, forming liquid film on the surfaces of the cutting tool and the workpiece. In step S4, the cutting tool and the workpiece and cooled, and liquid film is formed on the surfaces of the cutting tool and the workpiece.
