  • Publication number: 20210011555
    Abstract: An example method of identifying a touch gesture on a user is provided. The method includes receiving, by one or more transducers of a wearable device attached to an appendage of the user, a set of signals that propagate through the user's appendage and establish a signal pathway to the wearable device. The method also includes, while receiving the set of signals, determining baseline characteristics for the signal pathway, and sensing a change in the baseline characteristics caused by user interaction with an affordance of a user interface projected or perceived on the user's appendage. The method further includes, in accordance with a determination that the sensed change in the baseline characteristics satisfies a contact criterion, reporting a candidate touch event on the user's appendage to a separate electronic device that creates the user interface or is in communication with another electronic device that creates the user interface.

  • Patent number: 10866035
    Abstract: A wearable heat transfer device provides a user with haptic feedback providing sensations of hot or cold. The wearable heat transfer device comprises a heat source/sink and a programmable interface having heat transfer characteristics that are modified based on a signal received by the programmable interface. For example, a thickness of the programmable interface changes based on the received signal, altering heat transfer by the programmable interface. In another example, an electric field is applied to the programmable interface, changing one or more properties of the programmable interface affecting heat transfer.

  • Patent number: 10831272
    Abstract: A wearable device to be worn on a body part includes deformation sensors and a controller. The controller instructs the deformation sensors to measure deformation forces. The controller determines a position of the body part based on the measured deformation forces and a transfer function that maps deformation forces to positions of a same or corresponding body part. The transfer function is generated based on measurements from calibration and deformation sensors to sense corresponding positions of the body part and deformation forces. A calibration sensor may include a magnetic field generator and a magnetic flux sensor. The wearable device may be a glove and the body part may be a hand.

The method includes receiving, by one or more transducers of a first wearable device attached to a first appendage of the user, a set of signals transmitted by a second wearable device attached to the user, wherein (i) receiving the set of signals creates a signal pathway between the first and second wearable devices, and (ii) signals in the set of signals propagate through at least the user's first appendage. The method also includes determining baseline characteristics for the signal pathway created between the first wearable device and the second wearable device, sensing a change in the baseline characteristics while receiving the set of signals, and in accordance with a determination that the sensed change in the baseline characteristics for the signal pathway satisfies a contact criterion, report a candidate touch event on the user's first appendage.

  • Patent number: 10817049
    Abstract: A kinesthetic sensor measure angular displacement of body parts of users by measuring a density of substances contained in a conduit of the kinesthetic sensor. For example, the kinesthetic sensor measures the density of substance including in a conduit by transmitting a signal into the conduit and measuring the signal after the signal passes through the conduit and one or more substances included in the conduit. Based on the density of the one or more substances included in the conduit from the measured signal, an angular displacement of a user's body part proximate to the kinesthetic sensor is determined. Kinesthetic sensors may use different architectures such as an open-loop, a closed-loop architecture, or an architecture using blood vessels as conduits. Additionally, kinesthetic sensors can be flexible to conform to physical contours of different body parts.

  • Patent number: 10818433
    Abstract: Dielectric ceramic particulates are introduced into thin a sheet of pre-cured elastomer to form a sheet. Successive layers of the sheets may then be laminated together to form a finished article. An electric field may be applied to the article during a curing process while the article is at a temperature near a Curie temperature of the dielectric ceramic particulates to increase a dielectric constant of the article. As each sheet may be different from each other in the finished article, the resulting finished article may have anisotropic dielectric and mechanical properties. Similarly, tiled dielectric ceramic structures may be introduced into the elastomers layers to generate materials with varying dielectric constants.

    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.
