Title: Digital filter arrangement for ambient noise reduction, using an oversampled audio signal
Inventor: CLEMOW RICHARD
IPC: G10K11/178
Filed: 2006-04-12
Abstract: A digital circuit arrangement for an ambient noise-reduction system uses a low latency signal processing chain. The circuit arrangement includes a digital filter 82 which comprises a low pass filter to roll off the noise cancelling effect at higher frequencies, and preferably an IIR filter. The arrangement preferably converts analogue ambient noise signals, collected by microphone 13, into digital signals and then subjects the converted signals to digital filtering. The digital signals are N-bit digital signals at sample rate f0, where the value of N is no greater than 8, and fois at least 8 times the Nyquist sampling rate required for sampling of audio signals. This permits digital processing to be used without incurring group delay problems that rule out the use of conventional digital processing in this context. This arrangement is particularly suited to devices incorporating a loudspeaker in close proximity to the ear, such as headphones and telephone handsets.

Inventor: IRVING SUSAN
IPC: C07D405/12
Filed: 2012-05-16
Abstract: A process for the preparation of paroxetine hydrochloride hemihydrate that is substantially free from discolouration comprises treating discoloured paroxetine hydrochloride hemihydrate with one or more of an acidic alumina or a 3M Zetacarbon. The treatment may occur in solution (e.g. alcohol, IPA, IMS). Pink coloured paroxetine hydrochloride hemihydrate was slurred in 5% aqueous IPA (isopropyl alcohol) and heated to 70Â°C-75Â°C. Alumina was added. Subsequent filtration gave a clear, colourless filtrate. Upon cooling and filtration, a white to off-white crystalline solid (paroxetine hydrochloride hemihydrate) was obtained. The use of Zetacarbon type R55SP resulted in paroxetine hydrochloride hemihydrate as a white crystalline solid.

Abstract: The present method and system relate to categorizing URLs (Uniform Resource Locators) of web pages accessed by multiple users over an IP (Internet Protocol) based data network. The method and system collect real time data from IP data traffic occurring on the IP based data network, and extract parameters from the collected real time data, the parameters including an URL of a web page. The URL is processed by a rule based categorization engine, to associate a matching category to the URL of the web page. When no matching category is inferred, the URL is transferred to a semantic based categorization engine. A matching category is associated to the transferred URL by the semantic based categorization engine, based on a semantic analysis of the textual content extracted from the web page associated to the URL.
