Title: Method and apparatus for encoding and decoding using wavelet-packets
Inventor: COIFMAN RONALD
IPC: G06T9/00
Filed: 1991-05-17
Granted: 2001-07-17
Abstract: The disclosure involves the use of a library of modulated wavelet-packets which are effective in providing both precise frequency localiza-tion and space localization. An aspect of the disclosure involves feature extraction by determination of the correlations of a library of waveforms with the signal being processed while maintaining orthogonality of the set of waveforms selected (i.e. a selected advantageous basis). In a dis-closed embodiment, a method is provided for encoding and decoding an input signal, comprising the following steps (80): applying combinations of dilations and translations of a wavelet to the input signal to obtain processed values (1610); computing the information costs of the pro-cessed values (1620); selecting, as encoded signals, an orthogonal group of processed values, the selection being dependent on the computed in-formation costs (1630); and decoding the encoded signals to obtain an output signal (1640). The wavelet preferably has a plurality of vanishing moments.

Title: Process for the oxidation of cationic starches; amphoteric carboxylic and cationic starches thus produced
Inventor: SUC SOPHIE
IPC: C07H15/04
Filed: 1993-03-22
Granted: 1997-04-22
Abstract: This process consists in reacting a cationic starch with hydrogen peroxide and hydrobromic acid or bromine, in aqueous solution, so as to oxidise selectively the hemiacetal groups of the cationic starch and optionally the hemiacetal groups of its products of acidic hydrolysis, to carboxylic groups. The carboxylic and cationic amphoteric starch thus obtained is characterised in that its carboxylic groups originate from the selective oxidation of the hemiacetal groups of the cationic starch and, optionally, of the hemiacetal groups of its products of acidic hydrolysis.

Title: Controller for input-queued packet switch
Inventor: ENG KAI YIN
IPC: H04L12/56
Filed: 1993-04-13
Granted: 1999-06-22
Abstract: Significant throughput improvement is achieved for an input queued packet switch using output port schedulers by permitting the output schedulers to recycle or reassign cell transmission times from input ports which are unable to use them. When an output scheduler assigns a cell transmission time to an input port and that input port is unable to use the assigned transmission time due to a scheduling conflict, for example, the input port makes a new request for the same output port during the next subsequent request period and then returns the unable transmission time assignment back to the output scheduler. The output scheduler stores the returned transmission time in a separate queue for assignment to later requests for the particular output port. Throughput performance is improved from 58% (without time slot recycling) to 92% (with time slot recycling) for random packet cell trafficmodels,

Title: Methods and system for immediately connecting and reswitching digital cross-connect networks
Inventor: BOWDON EDWARD K
IPC: H04Q11/04
Filed: 1993-05-13
Granted: 2001-08-07
Abstract: A method and system to immediately connect and reswitch connection configurations through a rearrangeable communications matrix that immediately connects an input gate causing rearrangeably blocked condition through the communications matrix to an output gate through a dedicated or extra switching element of the center. With the rearrangeably blocked condition, the method and system select a set of switching elements pairs from the center stage switches to form a plurality of possible connections from the input gates to the output gates that excludes the dedicated switching element. The method and system then determines from the possible connections a minimum rearrangement connection configuration that excludes the dedicated switch and that requires the minimum number of rearrangements of existing communications matrix connections. Then, the invention reswitches the matrix according to the minimum rearrangement connection configuration while maintaining all signal flow from the input gates to the output gates while removing connections through the dedicated switching element. The preferred embodiment has particular application for digital cross-connect networks that include a time domain and a space domain for connection configurations where rearrangeably blocked condition may occur in either domain.

Granted: 1999-04-20
Abstract: The invention related generally to the preparation of colloidal metal(O) particles having a crosslinked aminodextran coating  with  pendent  amine  groups  attached  thereto.    The aminodextran acts as both a reductant for reducing metal ions to metal(O) particles and as the protective agent which coats the metal(O)  particles  thus  formed.     After  stabilizing  the aminodextran coating by use of a crosslinking agent, the coated particles can be used to covalently bind proteins.  The resulting protein containing colloidal particles can be used as markers in optical and electron microscopy, in immunological and biological assays, and possibly as therapeutic agents.

Granted: 2003-11-11
Abstract: A method for amplifying a target nucleic acid sequence by providing a polynucleotide such as VII including the sequence to be amplified as well as an RNA polymerase promoter sequence, and contacting said polynucleotide, in the presence of a system having RNA polymerase activity, RNA-dependent DNA polymerase activity, and DNA-dependent DNA polymerase activity, and capable of strand displacement, with a set of primers includinf a primer such as A capable of hybridising with a segment complementary to a portion of the sequence to be amplified, wherein A includes an upstream RNA polymerase promoter sequence then an arbitrary sequence, a primer such as D contains said RNA polymerase promoter sequence, and a primer such as C contains said arbitrary sequence. The elongation product of D is displaced by the elongation product of C, and the elongation product of D is thus obtained in the form of single-stranded VIII. Hybridisation of A on VIII followed by elongation forms double-stranded product X which can undergo transcription, with amplification, to give single-stranded RNA VII bis. An analogous system of 3 primers B, E and F similary produces single-stranded RNA VII from VII bis. Hence the amplification method, which can operate isothermally, is cyclic.

Abstract: A selectively actuatable lighter device (10) is disclosed which includes a body defining reservoir (12) for containing a combustible gaseous medium such as butane, and having a valve (20) arranged to be selectively actuated between a normal-ly closed position and an open position which permits the exit of the gaseous medium. Such lighter (10) can selectively pro-duce sparks at a location (19, 22) proximate to the gaseous me-dium exit to ignite the gaseous medium. Such lighter device (10) embodies a resiliently releasable valve actuator (14) which nor-mally prevents actuation of the valve (22). The valve actuator (14) includes an interfering portion (14A) which is selectively movable to a position (Fig.11) out of interference with an inter-fering portion (12A) of the lighter body, so that the gaseous me-dium may be released and ignited by the sparks. Once the valve actuator (14) is depressed and released, it returns to its closed or latched position to prevent actuation of the valve to the open position. To "re-use" the lighter, the valve actuator (14) must again be moved to an unlatched position so that the valve (22) can be actuated for subsequent ignition of the gaseous medium.
