20140369452 | METHOD AND APPARATUS FOR ON-DEMAND INTERFERENCE REJECTION IN MULTI-BAND GNSS RECEIVERS - In general, the present invention relates to an adaptive IF filter for a multiband receiver.

20140369536 | HEARING INSTRUMENT WITH OFF-LINE SPEECH MESSAGES - A hearing instrument configured for use with a device, the hearing instrument includes: an interface for reception of a message and/or a speech message from the device, wherein the speech message is a converted form of the message and is generated using a text-to-speech processor; a memory for storage of the message and/or the speech message, and a message processor configured for, at a selected time, outputting audio samples of the speech message for transmission to a user of the hearing instrument. | 2014-12-18 |
20140369537 | HEARING ASSISTANCE DEVICE WITH BRAIN COMPUTER INTERFACE - The present disclosure relates to communication devices. Such devices may comprise input for receiving sound signal to be processed and presented to a user, and output for outputting the processed signal to a user perceivable as sound. Such processing may be performed by use of a processor for processing the sound signal in dependence of a setting or a set of setting to compensate a hearing loss profile. Further, the communication device may comprise a bio-signal acquisition and amplifier component in communication with a user interface for providing the bio-signals as input to the user interface, the user interface controlling the setting or set of setting for operation of the communication device. | 2014-12-18 |
20140369538 | Assistive Listening System - The present disclosure describes methods and systems that can allow a digital signal processor (DSP) in an ultrasonic audio system to be adjusted according to a listener's preferences. In one embodiment, the listener or user can attempt to configure a DSP through a plurality of user interfaces. In another embodiment, the listener can provide an audiogram, previously generated by an audiologist, and send said audiogram to the manufacturer in order to adjust the DSP in the ultrasonic sound system to his/her hearing preferences. | 2014-12-18 |
