  • Publication number: 20240240621
    Abstract: A haptic device that includes SMA components that drive the actuating mechanisms of the haptic device, such as haptic arms. When a current is passed through the SMA components, due to the multiple local transformation temperatures, different sections of the SMA components have different reactions to the current in order to drive the actuating mechanisms.

  • Publication number: 20210062930
    Abstract: A shape memory alloy (SMA) valve including an SMA activator component having a shape memory effect to open or close the valve. The SMA valve may be formed from a monolithic sheet of SMA or a wire of SMA. The SMA valve may operate via choking, torsion or lateral movement in one or more dimensions. The SMA valve may include a stage or ball seal and the SMA actuator component may be provided to the stage or ball seal and configured to move the stage or ball seal to seal or open a flow of gas or liquid when the shape memory effect is activated. The SMA valve may include heat sinks to help adjust the temperature of the activator components and/or may include a biasing component to bias the valve in a particular direction.

  • Publication number: 20180347020
    Abstract: A method for treating a material comprising: applying energy to a predetermined portion of the material in a controlled manner such that the local chemistry of the predetermined portion is altered to provide a predetermined result. When the material is a shape memory material, the predetermined result may be to provide an additional memory to the predetermined portion or to alter the pseudo-elastic properties of the shape memory material. In other examples, which are not necessarily restricted to shape memory materials, the process may be used to adjust the concentration of components at the surface to allow the formation of an oxide layer at the surface of the material to provide corrosion resistance; to remove contaminants from the material; to adjust surface texture; or to generate at least one additional phase particle in the material to provide a nucleation site for grain growth, which in turn, can strengthen the material.

  • Publication number: 20170224444
    Abstract: A method and system for optimizing stiffness of an orthodontic archwire for a tooth malocclusion of a patient with a computer system, the method including: constructing a model of a patient's teeth in the computer system; inputting material properties of the archwire to the computer system; and determining an adjusted stiffness of a first section of the orthodontic archwire, the first section associated with the tooth malocclusion of the patient. In some cases, the adjusted stiffness may be determined based on different variables associated with the patient's teeth, which may include at least one of interbracket distance, malocclusion magnitude, bracket slot size, wire size, teeth size or extent of stiffness modification of the archwire.
