  • Patent number: 10537488
    Abstract: A self-aligning, self-drawing coupler for coupling body assemblies together improves usability of a wearable robotic device. A self-contained removable actuator cassette improves the ease of manufacture and of replacing parts in the field. A tensioning retention system designed for one handed operation makes donning and doffing a wearable robotic device easier. A two-stage attachment system increases the range of sizes a wearable robotic device will fit. A removable, integrated ankle-foot orthotic system makes donning and doffing a wearable robotic device easier. An infinitely adjustable, integrated ankle-foot orthotic system increases the range of sizes a wearable robotic device will fit. A manually-removable hip-wing attachment system makes field changes easier, and protecting such a system from inadvertent disengagement during operation increases safety.

  • Patent number: 10538310
    Abstract: A control system may be used to control actuators that actuate movement of flight control surfaces of an aircraft. Each actuator is couplable to a flight control surface and includes a motion control assembly having a hydraulic motor and a drive path from the hydraulic motor to the flight control surface. Each hydraulic motor includes an extend port and a retract port. The system includes a hydraulic control module fluidly connected to the extend port and the retract port of each hydraulic motor and a controller operable to output hydraulic power from the hydraulic control module to the motion control assembly to actuate movement of the flight control surfaces. The controller is configured to identify an actuator that positionally leads the other actuators and reduce hydraulic power to the motion control assembly assigned to such actuator.

  • Patent number: 10533670
    Abstract: A valve member having a first flow path and a second flow path, and configured to control both flow paths through a filter assembly. The valve member allows control of the two flow streams in a compact space compared to traditional valves. The valve member may require less space to operate due to its compact nature as compared to traditional external valves with multiple handles that each require space to rotate. The valve member may also be used to easily shut-off flow to a filter of a filter assembly without limiting use of another filtration assembly in the same filtration system. Alternatively, the valve member may shut off flow to a corresponding filter of a stand-alone filter assembly that is not connected to another filter assembly. Also, the valve member allows less expensive and more lightweight filtration systems.

  • Patent number: 10527142
    Abstract: A rotary hydraulic actuator may be configured to output rotary motion to control a hinged surface of an aircraft. The actuator includes a nested ballscrew, ballnut, and output assembly that form concentric ball races for converting the linear motion and force of the linear actuator to rotary motion and torque of the output assembly that is connected to the hinged surface. One of the ball races is helically inclined and the other of the ball races is linear. The rotary hydraulic actuator may include a ball return structure that returns the balls from a loaded path of a ball race to an unloaded path of the ball race. The ball return structure may define a ball return path that is located at the same radial distance from the actuator centerline as the loaded path for minimizing the overall diameter of the actuator.

  • Patent number: 10513343
    Abstract: A fuel pump includes a cartridge removably received within a canister. The cartridge includes a motor assembly, and a pump assembly that includes a centrifugal pumping element and outlet porting from the centrifugal pumping element. The motor drives the centrifugal pumping element to generate a flow of fluid through a main flow pathway between a pump inlet and outlet through the outlet porting of the pump assembly. The cartridge further includes a pressure relief valve that is movable between a closed position and an open position, and defines a pressure relief flow pathway integrally within the cartridge from the outlet porting to inlet porting of the centrifugal pumping element. When pressure within the pump assembly exceeds a threshold pressure, the pressure relief valve moves from the closed position to the open position to permit a relief flow of fluid through the relief flow pathway. The fuel pump may be employed as part of an aircraft fuel system.

  • Patent number: 10512888
    Abstract: Systems and methods provide automated parameter assurance features and results for consumables used in bioprocessing and particularly for purifying, filtering, harvesting and collecting bioprocessing fluids. Consumables having these features are sized, shaped, configured and constructed to interface with and be a component of such a bioprocessing system that includes a multi-use component or device with which it operatively engages such as by docking, engagement with a connector or other approach that allows for insertion and removal of the consumable. The consumable may be a component having a single-use life or a limited life. Each consumable has a median by which information, which can include use limits and specifications, is associated with that specific consumable, and those limits and specifications are communicated to the multi-use component which indicates any inappropriateness for use with the multi-use component.

  • Patent number: 10474943
    Abstract: A method of manufacturing a radio frequency identification (RFID) tag assembly (10) includes: forming an elastomeric body (12) made of an elastomeric material; providing an RFID tag (14); forming a patch (16) made of an elastomeric material; locating the RFID tag on a surface of the elastomeric body; overlaying the patch onto the RFID tag to cover the RFID tag with the patch; and bonding the patch to the elastomeric body, wherein the RFID tag is embedded within elastomeric material encompassed by the elastomeric body and the patch that overlays the RFID tag. The patch may be formed by die cutting the patch from the same elastomeric material component that is used to form the elastomeric body. The patch alternatively is formed separately from the elastomeric body from a dedicated source of elastomeric material, or formed by overlapping and bonding two ends of the elastomeric body to overlay the RFID tag embedded between the two ends.

  • Publication number: 20190314748
    Abstract: Filter systems, filters, and methods of managing filter systems are provided. The filter systems utilize large filters that are too large to be manually handled by service personnel. As such, the filter systems and methods utilize filter positioning units for handling the filters during maintenance intervals. Some systems include sensor for remotely monitoring the status of the filters and the information can be used to reverse pulse the filters as well as to indicate the end of the service life of the filters. The filters can be refurbished with new filter media.

  • Patent number: 10436331
    Abstract: A seal with a wedging element for adjustably compressing the seal. The seal abuts a surface, such as a gate of a gate valve, to seal against the surface with a sealing force that prevents fluid flow therebetween. The sealing force of the seal may be increasing or decreasing compression by adjusting the wedging mechanism. For example, as the seal wears away due to friction between the seal and a sliding gate, the compression may be increased in the wedging mechanism to increase the sealing force to a low threshold.

  • Publication number: 20190285181
    Abstract: A novel sealing member and a novel wedging element that may be part of a novel seal assembly. The seal assembly may remain effective for more connection/disconnection cycles as compared to the previously known seals. In exemplary embodiments, the wedging element may engage the sealing member or a pair of the sealing members that sandwich the wedging element. When engaged, an inclined surface of the wedging element may radially compress a radially inwardly extending sealing leg of one or both of the sealing members. A fluid pressure opposite the wedging element relative to the corresponding sealing member may radially expand a radially outwardly extending sealing leg of one or both of the sealing members.
