    Abstract: The present subject matter includes method and apparatus for an insulating layer applied to a battery to effectively increase the insulated separation between the anode and cathode contact surfaces of the battery. This increase in effective separation between anode and cathode decreases the probability that moisture applied to the battery will cause substantial ohmic conductivity between the anode and the cathode. Consequently, fewer batteries will be prematurely depleted or destroyed by moisture and fewer devices holding those batteries will need repair. The present subject matter serves to prevent or eliminate discharge of corrosive battery chemicals due to moisture and operating in wet environments. The life of batteries and devices using the present subject matter is thus extended. Additional method and apparatus can be found in the specification and as provided by the attached claims and their equivalents.

    Abstract: An apparatus is provided that includes an input system, an output system, and a sensor for sensing magnetic fields. In one example, a signal processing circuit electrically connects the input system to the output system, and a magnetic sensor adapted to inhibit the acoustic input and function as a magnetic input in the presence of a magnetic field. In one example, the magnetic sensor includes a giant magneto resistive (GMR) sensor. In another example, the magnetic sensor includes an anisotropic magneto resistive (AMR) sensor. The magnetic field can be generated by, among other things, a magnet in a telephone handset. The hearing aid further is programmed based on time-varying characteristics of the magnetic field. Wireless activation or deactivation of the hearing aid is also described. Other examples and options are provided herein.

    Abstract: One aspect relates to a method to block data transmission interference from an input of a receiver in a hearing instrument. In various embodiments, an acoustic-based signal representative of sound received at a microphone system is receiver. It is determined if a trigger associated with a data transmission has occurred. A signal representative of the acoustic-based signal is presented to the input of the receiver when the trigger has not occurred such that the receiver converts the acoustic-based signal into an output acoustic signal. The signal representative of the acoustic-based signal is blocked from the input of the receiver when the trigger has occurred such that data transmission interference is blocked from being converted into the acoustic signal. In various embodiments, the method further comprises presenting a signal representative of a substitute waveform to the input of the receiver when the trigger has occurred. Other aspects are provided herein.

    Abstract: Devices and methods are provided to enhance magnetic field communication. One aspect of the present subject matter relates to a method for transmitting and receiving signals using an antenna element electrically connected to a driver and an amplifier. According to various embodiments of the method, a first signal is transmitted from the antenna element and a second signal that was induced in the antenna element is received. Transmitting the first signal includes driving the first signal through the antenna element using the driver, and monitoring the first signal through an input impedance of the amplifier. Receiving the second signal includes reducing the input impedance of the amplifier, and receiving the second signal at the amplifier through the reduced input impedance. Various embodiments shield the antenna element from electric and electromagnetic fields. Other aspects are provided herein.

    Abstract: A field ready, unsupervised-use ready, method and apparatus for audio fitting a hearing aid is described in a hand held configuration having paired comparison (hearing selections) stored in and derivable from a memory therein. The paired comparisons are presented one at a time to a user and a preferred selection for each paired comparison is made by a select indicator after the user toggles back and forth between the selections for as many times necessary in determining their preferences. A genetic algorithm converges all the preferences upon a single solution. Crossover and mutation genetic algorithm operators operate on a linear range of indexes representative of parametric values of the pairs. A fully integrated hearing aid having all the above described features incorporated therein is also presented.
