  • Patent number: 10283232
    Abstract: An enhanced elastomer molding process applies an electric field to an elastomer doped to include dielectric ceramic particulates inserted in a cavity of a mold while maintaining a temperature at or near a melting point of the elastomer and a Curie temperature of the ceramic particulates. Because a material's dielectric constant is related to the material's net remnant ferroelectric polarization, which may be increased by poling near the material's Curie temperature, applying the electric field to the elastomer doped with the dielectric ceramic particulates increases the dielectric constant of the dielectric ceramic particulates. This maintains the high elasticity of the elastomer while increasing the elastomer's dielectric constant of the material by increasing the value of the dielectric constant of the dielectric ceramic particulates included in the elastomer.

  • Publication number: 20190063619
    Abstract: A fluidic device controls fluid flow in channel from a source to a drain. In some embodiments, the fluidic devices comprises a gate, a channel, and an obstruction. The gate comprises at least one chamber whose volume increases with fluid pressure. A high pressure state of the gate corresponds to a first chamber size and a low pressure state of the gate corresponds to a second chamber size that is smaller than the first chamber size. The obstruction controls a rate of fluid flow within the channel based on the fluid pressure in the gate. The obstruction induces at most a first flow rate of fluid in the channel in accordance with the low pressure state of the gate, and at least a second flow rate of the fluid in the channel in accordance with the high pressure state of the gate.

  • Patent number: 10216272
    Abstract: A strain measurement ring measures strain information describing deformation of a strain-sensitive element included in the strain measurement ring due to movement of a user's finger. The strain measurement ring includes a semi-rigid band coupled to a deformable band, which together encompass a portion of the user's body. The semi-rigid band includes two coupling ends each coupled to a respective coupling end of the deformable band. The deformable band includes the strain-sensitive element. The strain measurement ring may include an emitter to transmit strain information to a virtual reality/augmented reality (VR/AR) console. The strain measurement ring may include an actuator to change the tension of the deformable band in response to haptic command signals from a VR/AR console. As a result, the strain measurement ring may apply pressure to the user's skin to simulate contact with a virtual object.

  • Patent number: 10197459
    Abstract: A deformation sensing apparatus comprises an elastic substrate, a conductive element, and an additional conductive element. The conductive element includes conductive joints that are separated from each other by resolving elements along a length of the conductive element. Different combinations of conductive joints and resolving elements correspond to different segments of the deformation sensing apparatus. Based on a change in capacitance between a conductive joint and the additional conductive element when a strain is applied to the deformation sensing apparatus, the deformation sensing apparatus generates a signal that allows determination of how the strain deforms the deformation sensing apparatus.

  • Patent number: 10025386
    Abstract: An input interface for a virtual reality (VR) system includes one or more actuators stressing or straining a portion of a user's skin, simulating interactions with presented virtual objects. For example, an actuator comprises a tendon contacting portions of a user's body and coupled to a motor that moves the tendon to move portions of the user's body contacting the tendon. Alternatively, an actuator includes a pad having a surface contacting a surface of the user's body. A driving mechanism moves the pad in one or more directions parallel to the surface of the user's body with varying levels of normal force. In another example, one or more pins contact portions of the user's body and a surface of a bladder. The pins move as the bladder is inflated or deflated, which moves the contacted portions of the user's body. Alternatively, another type of actuator may move the pins.
