Patent HK-1142431-A1 (HK)
Title: Multichannel audio decoding
Inventor: DAVIS MARK FRANKLIN
IPC: H04S5/00
Filed: 2010-09-10
Abstract: Disclosed is a method for decoding M encoded audio channels representing N audio channels, where N is two or more, and a set of one or more spatial parameters having a first time resolution. The method comprises: a) receiving said M encoded audio channels and said set of spatial parameters having the first time resolution; b) employing interpolation over time to produce a set of one or more spatial parameters having a second time resolution from said set of one or more spatial parameters having the first time resolution; c) deriving N audio signals from said M encoded channels, wherein each audio signal is divided into a plurality of frequency bands, wherein each band comprises one or more spectral components; and d) generating a multichannel output signal from the N audio signals and the one or more spatial parameters having the second time resolution. M is two or more, at least one of said N audio signals is a correlated signal derived from a weighted combination of at least two of said M encoded audio channels, and said set of spatial parameters having the second resolution includes a first parameter indicative of the amount of an uncorrelated signal to mix with a correlated signal. Step d) includes deriving at least one uncorrelated signal from said at least one correlated signal, and controlling the proportion of said at least one correlated signal to said at least one uncorrelated signal in at least one channel of said multichannel output signal in response to one or ones of said spatial parameters having the second resolution, wherein said controlling is at least partly in accordance with said first parameter.

Abstract: PCT No. PCT/NO96/00189 Sec. 371 Date Mar. 8, 1999 Sec. 102(e) Date Mar. 8, 1999 PCT Filed Jul. 19, 1996 PCT Pub. No. WO97/04191 PCT Pub. Date Feb. 6, 1997In a method for regulating and optimizing transport of liquid in a porous structure by means of electroosmosis, a pulse pattern applied to one or more electrode pairs which are used during the electroosmosis is regulated by detecting a potential difference  INCREMENT Vp over the electrode pair or electrode pairs during the duration t3 of a neutral pulse which forms part of the pulse pattern and subsequently regulating either the duration t3 of the neutral pulse or the duration Tp of the pulse pattern or both on the basis of the detected potential difference  INCREMENT Vp and any change therein from measuring cycle to measuring cycle. A device for implementing the method comprises a power source with a pulse generator which supplies the desired pulse patterns to one or more electrode pairs (A, K) with the anode (A) provided in the porous structure and the cathode (K) in earth respectively, a voltage detector connected in series via each electrode pair (A, K) and a program control unit in a loop between the voltage detector and the power source's pulse generator.

Title: Method and apparatus for providing diversity in hard handoff for a cdma system
Inventor: TIEDEMANN EDWARD G JR
IPC: H04B7/02
Filed: 1999-09-09
Abstract: In a communications network, a network user communicates using a remote unit with another user via at least one base station. The communications network has a first base station having a first coverage area and a second base station having a second coverage area. In the situation where communication is not established between the second base station and the remote unit, in order to provide communication between the remote unit and the first base station when the remote unit is in the first coverage and simultaneously in the second coverage area, the first base station produces a first active communication signal at intended for the remote unit. The first base station transmits the first active communication signal from a first antenna. The base station delays the first active communication signal to produce a first delayed active communication signal and transmits it from a second antenna wherein the second antenna is oriented with respect to the first antenna such that the first active communication signal and the first delayed active communication signal fade independently as perceived by the remote unit. The first base station may measures a round trip delay of the first active communication signal in order to identify that the remote unit is located within the second coverage area.
