  • Patent number: 10327057
    Abstract: A headset in accordance with an embodiment of the present technology includes a headpiece, an earpiece, an arm extending therebetween, and a cord extending through the arm. The arm includes elongate first and second segments through which the arm is operably connected to the earpiece and the headpiece, respectively. The first and second segments have a telescoping arrangement such that the arm is movable between a lengthened state and a shortened state. The arm further includes a hinge operable to rotate the arm about an axis and thereby move the arm relative to the headpiece between a folded state and an unfolded state. Increased slack in the cord preferentially gathers within an interior region of the second segment when the arm moves from the lengthened state toward the shortened state and when the arm moves from the folded state toward the unfolded state.

  • Publication number: 20180177508
    Abstract: An embodiment of the invention is a shape memory polymer (SMP) foam designed to recover its original shape through exposure to a solvent. Thermo-responsive SMPs are polymers designed to maintain a programmed secondary shape until heated above their transition temperature, upon which the polymer recovers its original, or primary, shape. The thermo-responsive SMP foam is programmed to its secondary shape prior to use, typically compression of the foam to a small volume, and remains in this programmed shape until exposed to a selected solvent such as dimethyl sulfoxide or ethyl alcohol. Upon exposure to the solvent, the transition temperature of the SMP foam decreases below the temperature of the environment and the SMP foam actuates to its primary shape. The SMP foam is tailored to actuate upon exposure to specific solvents while minimizing or preventing actuation when exposed to water or other solvents.

  • Publication number: 20170362372
    Abstract: New shape memory polymer compositions, methods for synthesizing new shape memory polymers, and apparatus comprising an actuator and a shape memory polymer wherein the shape memory polymer comprises at least a portion of the actuator. A shape memory polymer comprising a polymer composition which physically forms a network structure wherein the polymer composition has shape-memory behavior and can be formed into a permanent primary shape, re-formed into a stable secondary shape, and controllably actuated to recover the permanent primary shape. Polymers have optimal aliphatic network structures due to minimization of dangling chains by using monomers that are symmetrical and that have matching amine and hydroxyl groups providing polymers and polymer foams with clarity, tight (narrow temperature range) single transitions, and high shape recovery and recovery force that are especially useful for implanting in the human body.
