  • Publication number: 20220316458
    Abstract: A remote actuator includes one or more bi-stable strips with at least one shape memory composite (SMC) spring connected to each bi-stable strip. The SMC spring includes a thermoplastic and an electrical and/or thermal conductor for transforming the length of the SMC spring upon heating. The contraction of the SMC spring transforms the bi-stable strip from its coiled stable state to its elongated stable state. The displacement of the SMC spring can be amplified by a simple machine included in the remote actuator. The remote actuator can include a shape memory alloy (SMA) strip for transforming the bi-stable strip from its elongated stable state to it curved stable state upon heating. Heating can be by Joule heating or from an adjacent heat source.

  • Publication number: 20220307485
    Abstract: An actuator for a vehicle seat can be configured to prevent overstress of a shape memory alloy (SMA) wire. The actuator can include a first body member and a second body member pivotably connected to each other. The actuator can include an overstress post and an overstress contact plate operatively connected to the overstress post. Thus, movement of the overstress post causes movement of the overstress contact plate. The actuator can include an overstress contact pin. The actuator can include an SMA wire operatively connected to one of the body members and to the overstress post. When activated, the SMA wire can shrink, causing one of the body members to pivot relative to the other body member and causing the overstress contact plate to move toward the overstress contact pin. If the overstress contact plate contacts the overstress contact pin, the SMA wire can be deactivated.

  • Publication number: 20220297609
    Abstract: A system for using an electrostatic force to cause an object to adhere to a surface of a vehicle can include an electrode and a device. The electrode can be configured to be disposed within a structure of the vehicle. The structure can define the surface. A shape of the electrode can define a shape of a region of the surface. The device can be configured to connect the electrode to a voltage source so that, at a time at which the electrode is connected to the voltage source, an electric charge is produced on the electrode to produce the electrostatic force capable of causing the object to adhere to the surface. For example, the surface can include a dashboard, a dashboard vent frame, a sunglasses holder cover, or the like. For example, the object can include a mobile device, a cup, a pair of sunglasses, or the like.

  • Publication number: 20220268268
    Abstract: A two-stage pump system is provided using electrostatic actuators. The system includes a pair of hydraulically-amplified, self-healing, electrostatic (HASEL) actuators in fluid communication with one another. Each actuator includes a deformable shell defining a working fluid compartment storing a dielectric fluid. Two electrodes are disposed on opposite sides of the deformable shell. A pair of fluid transfer bladders are disposed adjacent the respective pair of HASEL actuators, each including a fluid-impermeable membrane defining a transfer fluid chamber, and a biasing member disposed in the transfer fluid chamber. When individually actuated in an alternating two-stage pattern, the two electrodes of each respective HASEL actuator move from a neutral position to an attracted position, displacing dielectric fluid through the first transfer conduit and between working fluid compartments, thereby pumping the transfer fluid from an inlet to an outlet.

  • Publication number: 20220242328
    Abstract: A cargo organizer is constructed from one or more bi-stable strips with at least one shape memory alloy (SMA) actuator per bi-stable strip. The cargo organizer can reside in the bi-stable strips elongated (flat) stable state and require little or no volume of the cargo compartment that it resides. Upon actuating a SMA actuator, the rapid conversion to the curved stable state can occur with the formation of a barrier to partition the cargo compartment into at least to portions. The transformation into the flat stable state removes the partition where the transformation can be via a second SMA actuator or manually. The cargo organizer can be incorporated into the cargo compartment in a manner that it translates from one site and orientation to one or more other sites or orientations by activation an actuator that can be an additional SMA actuator.

  • Patent number: 11370330
    Abstract: A vehicle seat can be configured to selectively provide support to a vehicle occupant in conditions when lateral acceleration is experienced. An actuator can be located within the vehicle seat. When activated, the actuator cause a portion of the seat to morph into an activated configuration. The actuator can be activated based on vehicle speed, steering angle, and/or lateral acceleration. The actuator can include end members connected by a shape memory material connecting member. Actuator blocks with sliding surfaces can be located between the end members. The actuator can be configured such that, in response to an activation input, the shape memory material connecting member contracts, which draws the end members toward each other and causes corresponding sliding surfaces of the plurality of actuator blocks to engage and slide relative to each other. In this way, the actuator morphs into an activated configuration in which its overall height increases.
