20090103765Headset for fitting of an earpiece - Headset for fitting an earpiece that has a lock housing in or on which a fixing device is provided. A flexurally rigid and elastic ear loop which forms a loop for accommodating the outer ear of a user, and one end of the ear loop is received longitudinally displaceable in the fixing device of the lock housing, and for adjusting the size of the loop is adjustably received in various length positions, creating a fixing effect. There is a control device for receiving and outputting electrical signals and a signal interface for receiving and/or outputting electrical signals to and/or from the control device.04-23-2009
20100128907SYSTEM AND METHOD FOR PROVIDING HEARING ASSISTANCE TO A USER - A hearing assistance system, having an audio signal source, a transmission unit for transmitting audio signals from the audio signal source via a wireless right ear audio link to a right ear unit and a receiver unit, and an arrangement for stimulating the user's right ear, and via a wireless left ear audio link, a left ear unit having a receiver unit and an arrangement for stimulating the user's left ear, an arrangement for exchanging audio signals received from the transmission unit between the right and left ear units, a device for detecting the quality of the right and left ear links and an arrangement for selecting, as a function of the detected qualities of the right and left ear links, as input to the stimulating arrangement, the audio signals received by the respective receiver unit from the transmission unit, the audio signals received via the audio signal exchanging arrangement, and/or mixtures thereof.05-27-2010
20100150387SYSTEM AND METHOD FOR PROVIDING HEARING ASSISTANCE TO A USER - A system for providing hearing assistance to a user having an audio signal source, a transmission unit for transmitting audio signals from the audio signal source via a wireless right ear audio link to a right ear unit having a receiver unit and a device for stimulating the user's right ear according to the audio signals received from the transmission unit and via a wireless left ear audio link to a left ear unit having a receiver unit and means for stimulating the user's left ear according to the audio signals received from the transmission unit, and a device for delaying the stimulation of one of the user's ears with the audio signals received from the transmission unit relative to the stimulation of the other one of the user's ears with the audio signals received from the transmission unit by 1 msec to 10 msec.06-17-2010
20100278365METHOD AND SYSTEM FOR WIRELESS HEARING ASSISTANCE - A method for providing hearing assistance to a user, comprising capturing audio signals by a microphone arrangement; measuring at least one mechanical parameter; selecting an audio signal processing scheme according to the measured at least one mechanical parameter; processing, by a signal processing unit, the captured audio signals according to the selected audio signal processing scheme; transmitting the processed audio signals to stimulating means worn at or in at least one of the user's ears via a wireless audio link; and stimulating the user's hearing by said stimulating means according to the processed audio signals.11-04-2010
20100278366METHOD AND SYSTEM FOR WIRELESS HEARING ASSISTANCE - A method for providing hearing assistance to a user, comprising capturing audio signals by an internal microphone arrangement and supplying the captured audio signals a central signal processing unit; estimating whether a certain type of external audio signal supply device is connected to the audio signal processing unit in order to supply external audio signals to the central signal processing unit, and selecting an audio signal processing scheme according to the estimated type of external audio signal supply device; processing, the captured audio signals and the external audio signals according to the selected audio signal processing scheme; transmitting the processed audio signals to stimulating means worn at or in at least one of the user's ears via a wireless audio link; and stimulating the user's hearing by said stimulating means according to the processed audio signals.11-04-2010
20110188683METHOD FOR MONITORING A HEARING DEVICE AND HEARING DEVICE WITH SELF-MONITORING FUNCTION - A method for monitoring a hearing device having an electroacoustic output transducer worn at a user's ear or in a user's ear canal, the method including: measuring the electrical impedance of the output transducer; analyzing the measured electrical impedance of the output transducer in order to determine at least one parameter from the length and diameter of tubing that extends into the user's ear canal and is connected to the transducer, and adjusting operation parameters of the hearing device based upon the results of the determination so as to optimize acoustical performance of the hearing device. A hearing device in which the method is implemente08-04-2011

20090075575Method for Producing a Netted Casing - The invention relates to a method for producing a shirred food casing covered by a net, and a method for combining a net with a surface of a carrier casing, said method comprising steps wherein air or an inert gas is blown into the carrier casing, the carrier casing inflated/pressurized to be round is pulled in the direction of the tubular net towards a pleating head attached to one end of the tubular net, said net being attached at the open end thereof to a clamp centralized with a shirring mandrel, the carrier casing being thus folded into the tubular net while pulling the net inside out over itself, followed by pulling the carrier casing through the pleating head to the shirring machine where the pressure of air or an inert gas blown from inside of the shirring mandrel forces the areas of the carrier casing between the meshes of the net to form bulges, and finally the net/carrier casing combination is shirred by the shirring machine. The invention is further directed to a shirred product produced with the method.03-19-2009
