    Abstract: A processor comprises instructions to adjust a bias of an input signal in order to decrease a duty cycle of a pulse modulated optical signal. The bias can be increased, decreased, or maintained in response to one or more measured values of the signal. In many embodiments, a gain of the signal is adjusted with the bias in order to inhibit distortion. The bias can be adjusted slowly in order to inhibit audible noise, and the gain can be adjusted faster than the bias in order to inhibit clipping of the signal. In many embodiments, one or more of the bias or the gain is adjusted in response to a value of the signal traversing a threshold amount. The value may comprise a trough of the signal traversing the threshold.

    Abstract: Systems, devices and methods for communication include an ear canal microphone configured for placement in the ear canal to detect high frequency sound localization cues. An external microphone positioned away from the ear canal can detect low frequency sound, such that feedback can be substantially reduced. The canal microphone and the external microphone are coupled to a transducer, such that the user perceives sound from the external microphone and the canal microphone with high frequency localization cues and decreased feedback. Wireless circuitry can be configured to connect to many devices with a wireless protocol, such that the user can receive and transmit audio signals. A bone conduction sensor can detect near-end speech of the user for transmission with the wireless circuitry in a noisy environment. Noise cancellation of background sounds near the user can be provided

    Abstract: A transducer is configured to couple to the cochlear fluid so as to transmit sound with low amounts of energy, such that feed back to a microphone positioned in the ear canal is inhibited substantially. The cochlear fluid coupled hearing device can allow a user to determine from which side a sound originates with vibration of the cochlea and the user can also receive sound localization cues from the device, as feedback can be substantially inhibited. The transducer may be coupled to the cochlear fluid with a thin membrane disposed between the transducer and the cochlear fluid, for example with a fenestration in the cochlea. In some embodiments, a support coupled to the transducer directly contacts the fluid of the cochlea so as to couple the transducer to the cochlear fluid.

    Abstract: Contact hearing devices for use with a wearable communication apparatus are disclosed to provide the user with an open ear canal to hear ambient sound and sound from an audio signal. The disclosed devices and systems have an advantage of providing sound to user from the audio signal, in many embodiments without creating sound that can be perceived by others. The contact hearing device can also be used to amplify ambient sound to provide a hearing assistance to users with diminished hearing. The wearable information apparatus can be configured to couple wirelessly to the contact transducer assembly, such that the wearable information apparatus can be removed while the contact transducer assembly remains placed on the user.

    Abstract: An output transducer is coupled to a support structure, and the support structure configured to contact one or more of the tympanic membrane, an ossicle, the oval window or the round window. An input transducer is configured for placement near an ear canal opening to receive high frequency localization cues. A sound inhibiting structure, such as an acoustic resistor or a screen, may be positioned at a location along the ear canal between the tympanic membrane and the input transducer to inhibit feedback. A channel can be coupled to the sound or feedback inhibiting structure to provide a desired frequency response profile of the sound or feedback inhibiting structure.
