  • Publication number: 20200385308
    Abstract: A method of fabricating a variable diameter fiber includes providing a fiber optic cable comprising a cladding region, a fiber core, and a plurality of sacrificial regions disposed in the cladding region and focusing a laser beam at a series of predetermined locations inside the fiber optic cable. The method also includes creating a series of damage sites associated with the series of predetermined locations, wherein the series of damage sites define a variable diameter profile and a latticework in the cladding region of the fiber optic cable. The method further includes exposing the fiber optic cable to an etchant solution, preferentially etching the series of damage sites, and separating peripheral portions of the fiber optic cable to release the variable diameter fiber.

  • Publication number: 20200197703
    Abstract: A signal processing arrangement is described for signal processing in a bilateral hearing implant system. A channel compression module develops a inhibition-adjusted band pass signal for each band pass signal using a channel-specific dynamic inhibition adjustment based on a channel-normalized medial olivocochlear reflex model that reflects bandwidth energy for a corresponding contralateral band pass signal and bandwidth energy for a selected reference contralateral band pass signal.

  • Patent number: 10502948
    Abstract: A fiber scanning system can have optimized performance by substantially matching the natural frequencies of the fiber scanning system's actuator and fiber optic scanning element. By matching the natural frequencies, the fiber scanning system can increase the maximum distance that the tip of the fiber optic scanning element may be driven relative to a resting position. Such an effect may be produced because matching the natural frequencies of the fiber scanner allows for larger amplitudes to be achieved. It should be noted that the natural frequency of the scanning system can be selected to avoid excitation frequencies that could destabilize the system. In this way, the system as a whole may act as a tuned mass damper or a tuned resonance structure, thereby improving scan performance while maintaining a stable scanning system.
