  • Publication number: 20200269088
    Abstract: A method for determining biomechanical parameters of the stride of a runner, using an accelerometer device on the wrist, on the upper arm, on the head or on the shoe, comprising the steps of measuring an initial sequence of acceleration data in at least the vertical direction using said accelerometer device; identifying in said initial sequence of acceleration data at least one frequency component caused by relative motion of the accelerometer device relative to the runner center of masse; attenuating said frequency component, so as to determine a modified sequence of acceleration data; determining said biomechanical parameters from said modified sequence of acceleration data.

  • Publication number: 20200257363
    Abstract: Electromechanical polymer (EMP) actuators are used to create haptic effects on a user interface deface, such as a keyboard. The keys of the keyboard may be embossed in a top layer to provide better key definition and to house the EMP actuator. Specifically, an EMP actuator is housed inside an embossed graphic layer that covers a key of the keyboard. Such a keyboard has a significant user interface value. For example, the embossed key provides the tactile effect of the presence of a key with edges, while allowing for the localized control of haptic vibrations. For such applications, an EMP transducer provides high strains, vibrations or both under control of an electric field. Furthermore, the EMP transducer can generate strong vibrations. When the frequency of the vibrations falls within the acoustic range, the EMP transducer can generate audible sound, thereby functioning as an audio speaker.

  • Patent number: 10709871
    Abstract: A catheter includes an electromechanical polymer (EMP) actuator disposed in a steerable tip at the distal end of the catheter. When activated, the EMP actuator deflects the steerable tip through an angle between 0 and 270 degrees, thus permitting the operator to steer the steerable tip through the vasculature. The steerable tip also has at least a first relatively stiff region and a second relatively flexible region, and the EMP actuator is provided next to the first relatively stiff region so that the steerable tip may toward the flexible region when activated. In one implementation, an external interface allows a user to select by name one of many sets of control signals, with each set of control signals being signals calibrated for configuring the catheter to mimic a known catheter.

  • Patent number: 10503255
    Abstract: A system with a touchscreen generates haptic effects in response to a manipulation of text displayed on the touchscreen. The system senses a touch within the text, and determines if the touch is a manipulation of the text, and determines the type of the manipulation. The system then generates a type of haptic event that is based at least in part on the type of the manipulation that was determined.

  • Patent number: 9705068
    Abstract: An inertial actuator includes an electro-active polymer EAP actuator, a substrate, and one or more mass elements. The EAP actuator includes at least one EAP layer located between a pair of driving electrodes. The EAP actuator may include a multilayer stack of alternating EAP layers and electrode layers. The EAP actuator is attached to the substrate (e.g., a flexible polymer substrate), which may be held under tension by attachment points at the periphery of the substrate, at the ends of a beam-type substrate, or the edges of a membrane-type actuator. The EMP actuator induces vibrations in the substrate. One or more mass elements (e.g., metal films) may also be supported by the substrate to enhance the resonator response.
