AI Technical Summary

Benefits of technology

The present invention relates to methods and coatings for preventing fluid ingress in rechargeable batteries used in hearing aids. The technical effect of this invention is to provide better protection against moisture ingress in hearing aid systems, particularly in the battery and its associated components, to prevent damage and malfunctions caused by moisture.

Problems solved by technology

Because of the environment in which many hearing aids operate the BTE / processor and internal electronics are exposed to various forms of moisture.
Ingress of that moisture into the BTE / processor may result in deleterious effects.
The deleterious effects of moisture ingress are particularly significant when the moisture impacts the battery.
Moisture which comes in contact with a battery, including the electronics and recharging circuitry around the battery has deleterious impact on the function of the battery, including shorting and / or the creation of corrosion, particularly in the presence of electric fields, such as those generated when the battery is being charged.

Embodiment Construction

[0043]FIG. 1 is a schematic illustration of a hearing aid system 10, including a contact hearing device 20 according to the present invention. In FIG. 1, audio processor 30 is connected to light tip 120 by cable 260, which includes taper tube 250. Light tip 120 is adapted to radiate light pulses 40 to tympanic lens 100 which is positioned on a user's tympanic membrane TM in a manner which allows it to drive the user's umbo UM directly.

[0044]FIG. 2 is a block diagram of a hearing aid system 10 according to the present invention. In FIG. 2, sound 340 is detected by microphone 310, which is connected to analog to digital converter 320. Sound signals processed by analog to digital converter 320 are transmitted to digital signal processor 330. Digital signal processor 330 is, in turn, connected to emitter 290, which radiates light 40 to photodetector 130. The output of photodetector 130 drives microactuator 140, which includes umbo lens 220. Umbo lens 220 is positioned on a user's tympan...
