20080300702	MUSIC SIMILARITY SYSTEMS AND METHODS USING DESCRIPTORS - Systems and methods for determining similarity between two or more audio pieces are disclosed. An illustrative method for determining musical similarities includes extracting one or more descriptors from each audio piece, generating a vector for each of the audio pieces, extracting one or more audio features from each of the audio pieces, calculating values for each audio feature, calculating a distance between a vector containing the normalized values and the vectors containing the audio pieces, and outputting a response to a user or process indicating the similarity between the audio pieces. The descriptors can be used in performing content-based audio classification and for determining similarities between music. The descriptors that can be extracted from each audio piece can include tonal descriptors, dissonance descriptors, rhythm descriptors, and spatial descriptors.	12-04-2008

20100303267	LISTENING DEVICE PROVIDING ENHANCED LOCALIZATION CUES, ITS USE AND A METHOD - The invention relates to a listening device comprising an ear-part adapted for being worn in or at an ear of a user, a front and rear direction being defined relative to a person wearing the ear-part in an operational position. The invention further relates to a method of operating a hearing instrument, to its use, to a listening system, to a computer readable medium and to a data processing system. The object of the present invention is to provide localization cues for indicating a direction of origin of a sound source. The problem is solved in that the listening system comprises (a) a microphone system comprising at least two microphones each converting an input sound to an electrical microphone signal, (b) a DIR-unit comprising a directionality system for providing a weighted sum of the at least two electrical microphone signals thereby providing at least two directional microphone signals having maximum sensitivity in spatially different directions and a combined microphone signal, and (c) a frequency shaping-unit for modifying the combined microphone signal to indicate directional cues of input sounds originating from at least one of said spatially different directions and providing an improved directional output signal. This has the advantage of providing an alternative or an addition to natural localization cues. The invention may e.g. be used in listening devices, e.g. hearing instruments, head phones, headsets or active ear plugs.	12-02-2010
20110249843	SOUND PERCEPTION USING FREQUENCY TRANSPOSITION BY MOVING THE ENVELOPE - The application relates to a method of improving a user's perception of an input sound. The application further relates to an audio processing device and to its use. The object of the present application is to increase the sound quality of a sound signal as perceived by a user, e.g. a hearing impaired user. The method comprises a) Defining a critical frequency f	10-13-2011

20110177300	DICHROIC GLASS FOR COSMETIC APPEAL IN AN ELECTRONIC DEVICE - A dichroic coating can be applied to a glass window of an electronic device to enhance the cosmetic and aesthetic appeal of the device. Different processes can be applied to the glass window in combination with a dichroic coating. For example, a layer of ink can be applied to the glass window in addition to one or more layers of dichroic material. The material layers can cover any suitable portion of the glass. For example, the material layers can include holes or openings. As another example, the material layers can be constructed from several distinct shapes placed on the glass. In some cases, software applications can be used to define a desired color profile for a coating, and to retrieve a suitable combination of dichroic and other layers to provide the desired color profile.	07-21-2011

20120016443	RATE MATCHING FOR A STIMULATING MEDICAL DEVICE - Methods and systems are disclosed for rate matching in a stimulating medical device, such as a cochlear implant or an auditory brain stimulator. In embodiments, the stimulating medical device applies a fast Fourier transform (FFT) at an analysis rate to the received signal to obtain a plurality frequency bin output signals. The stimulating medical device then applies a rate matching through interpolation function to the frequency bin output signals to match the stimulation rate for the stimulating medical device. This rate matching through interpolation function may apply a common interpolation filter to each frequency bin output to obtain a plurality of outputs distributed in time across the time period between executions of the FFT. The values of the frequency bin output signals at the time most closely matching the time for which stimulation is to be applied may then be selected and used in applying the stimulation.	01-19-2012

20090303730	Light Fixture Having A Glare-Eliminating Optical System - An undercabinet light fixture, comprising a housing for supporting a light source. A glare-eliminating optical system is mounted on the housing and through which light illuminated by the light source passes. The glare-eliminating optical system includes a textured surface and a non-textured surface. The textured surface includes an array of longitudinally extending prismatic elements for redirecting light illuminated from the light source. The non-textured surface is located below the light source and permits light illuminated from the light source to pass therethrough without being substantially redirected.	12-10-2009
