  • Patent number: 11924374
    Abstract: Real time, remote access to and adjustment of the hearing aid of a patient while the patient is located in a normal life environment that is remote from a hearing professional. A session request initiates a programming session. Adjustable settings from the patient's hearing aid are wirelessly streamed to the patient's mobile device and from the mobile device to a streaming cloud server. The settings are stored on the cloud, streamed from the cloud to a hearing professional's computer or mobile device and displayed. The hearing professional then changes at least one of the adjustable hearing aid settings and the changed settings are streamed to the cloud, stored on the cloud, streamed from the cloud to the patient's mobile device, wirelessly transmitted to the hearing aid and stored there. A telephonic voice connection between the hearing professional and the patient's mobile device is used to transmit the patient's evaluation of changed settings to the hearing professional.

  • Patent number: 11917355
    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.
