  • Patent number: 11206472
    Abstract: Embodiments describe an acoustic shielding component including a stiffener formed of a rigid material providing structural integrity to the acoustic shielding component, a cosmetic mesh comprising a plurality of interlaced wires, and an acoustic mesh disposed between the stiffener and the cosmetic mesh. The stiffener includes first and second walls extending along a length of the stiffener and a plurality of ribs spaced apart from each other and extending between the first and second walls. The cosmetic mesh includes a mesh cover disposed over the stiffener and having an outer surface and an inner surface, and a mesh wall extending from an outer periphery of the inner surface of the mesh cover and defining a tab.

  • Publication number: 20210314696
    Abstract: An earphone includes a housing that defines a force input surface opposite a touch input surface. A spring member in the housing includes a first arm that biases a touch sensor toward the touch input surface. The spring member also includes a second arm that biases a first force electrode toward the housing and allows the first force electrode to move toward a second force electrode when a force is applied to the force input surface. A non-binary amount of the force is determinable using a change in a mutual capacitance between the first force electrode and the second force electrode. The mutual capacitance between the first force electrode and the second force electrode may be measured upon detecting a touch using the touch sensor.

  • Patent number: 11096657
    Abstract: A laser light source transmits laser light to a tip of an interventional instrument such as a needle via an optical fiber. The laser light is absorbed at the distal tip of the instrument and generates a photoacoustic signal. The laser light source is configured to receive a trigger signal from an ultrasound machine when a laser pulse is to be produced. The light source signals the ultrasound machine when an optical connector is connected to the laser light source to automatically begin a needle tip (NTV) visualization mode. If the optical connector is removed from the laser light source, the laser light source stops producing laser light pulses.

  • Patent number: 11102563
    Abstract: Embodiments describe an attachment mechanism including a wire bent in various directions forming a spring compressible in lateral directions. The wire includes a first wireform feature and a second wireform feature extending from the first wireform feature, where the first wireform feature and the second wireform feature each include: an intermediate segment; a u-shaped segment extending from the intermediate segment; and an end segment extending from the u-shaped segment.

  • Publication number: 20210243514
    Abstract: Embodiments describe an eartip including an eartip body having an attachment end and an interfacing end opposite from the attachment end, and including an inner eartip body and an outer eartip body. The inner eartip body has a sidewall that extends between the interfacing end and the attachment end, and includes a groove formed in an outer surface of the sidewall. The outer eartip body is sized and shaped to be inserted into an ear canal and extends from the interfacing end toward the attachment end of the eartip.

  • Publication number: 20210219042
    Abstract: An earphone includes a speaker housing; a speaker positioned in the speaker housing; a stem extending from the speaker housing, the stem defining an input surface; a conductive object disposed within the stem; a flexible circuit positioned between the stem and the conductive object; a member positioned between the flexible circuit and the conductive object operable to allow the flexible circuit to move with respect to the stem; a force sensor electrode disposed within the flexible circuit; and a controller operable to determine an input to the earphone using a change in capacitance detected using the force sensor electrode, the change in capacitance corresponding to a non-binary amount of a force applied to the input surface. In some examples, the earphone further includes a touch sensor electrode disposed within the flexible circuit.
