    摘要: Systems and methods determine a fluid efficiency of a fluid that flows through a fluid power system. A magnetic flux gradient generated by a magnetic fluid filter positioned on a flow path as the fluid flows through the magnetic fluid filter is monitored in real-time by a fluid monitoring device that is coupled to the fluid power system. A fluid status is determined in real-time that is associated with the magnetic flux gradient from fluid parameters associated with the magnetic flus gradient as detected by the fluid monitoring device. The fluid status of the fluid is determined in real-time that indicates that a corrective action is to be executed to increase a quality of the fluid based on the fluid parameters detected by the fluid monitoring device. The degradation to components of the fluid power system increases without the corrective action being executed to increase the quality of the fluid.

    摘要: An artificial muscle that includes a housing having an electrode region and an expandable fluid region, a dielectric fluid housed within the housing, an electrode pair positioned in the electrode region of the housing, the electrode pair including a first electrode and a second electrode, and an electrode insulator having one or more insulation layers. The electrode insulator is disposed on an inner electrode surface of the first electrode of the electrode pair. The second electrode includes a free inner electrode surface exposed to the dielectric fluid when the electrode pair is in a non-actuated state. The electrode pair is actuatable between the non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region.

    摘要: A dynamic interface between a vehicle windshield and a structure (e.g., an A-pillar) is provided. The dynamic interface can be actively managed to allow its configuration to be selectively changed based on real-time driving environment conditions. The interface can include one or more actuators that can be selectively activated or deactivated to change the aerodynamic characteristics of the interface. When a crosswind activation condition is detected, the actuator(s) can be activated. The actuator(s) can be soft-bodied structures. The actuator(s) can include a bladder defining a fluid chamber filled with a dielectric fluid. A first conductor and a second conductor can be operatively positioned on opposite portions of the bladder. When electrical energy is supplied to the conductors, they can become oppositely charged. As a result, the conductors can be electrostatically attracted toward each other, displacing some of the dielectric fluid to an outer peripheral region of the fluid chamber.

    摘要: A pressure pin of a press, in particular a forming press, for transferring a force to a tool component of the press includes a pin body, a sensor element arranged in the pin body for measuring a force which can be transferred via the pressure pin, and an actuator unit arranged in the pin body which has a functional body made of an adaptive material. The adaptive material is designed such that the rheological properties thereof and/or the length thereof and/or the volume thereof can be selectively modified as a function of an electrical and/or magnetic field.

    摘要: An electro-hydraulic actuator includes a deformable shell defining an enclosed internal cavity and containing a liquid dielectric, first and second electrodes on first and second sides, respectively, of the enclosed internal cavity. An electrostatic force between the first and second electrodes upon application of a voltage to one of the electrodes draws the electrodes towards each other to displace the liquid dielectric within the enclosed internal cavity. The shell includes active and inactive areas such that the electrostatic forces between the first and second electrodes displaces the liquid dielectric within the enclosed internal cavity from the active area of the shell to the inactive area of the shell. The first and second electrodes, the deformable shell, and the liquid dielectric cooperate to form a self-healing capacitor, and the liquid dielectric is configured for automatically filling breaches in the liquid dielectric resulting from dielectric breakdown.
