Title: Transmission system with reconstruction of missing signal samples
Inventor: KATHMANN ERIC
IPC: G10L19/005
Filed: 1994-07-29
Abstract: ABSTRACT: Transmission system with reconstruction of missing signal samples.     In a transmission system only part of the signal samples of series of transmit signal samples is transmitted by the transmitter (2) to a receiver (6) over a channel (4). In addition, a number of characteristic parameters of the series of signal samples are determined in the transmitter by characterization means (12) and transmitted to the receiver. The characteristic parameters are used at the receiver end (6) for reconstructing the missing signal samples. This is a effected by assigning to the missing signal samples a value, so that the series of signal samples is described in the best way possible by the characteristic parameters. It appears that if periodicities having a period longer than the time duration of the series of signal samples occur, the reconstruction of the signal samples is accompanied by a considerable interpolation error. By determining this period in the transmitter (2), transmitting same over the channel (4) to the receiver (6) and introducing this periodicity in the receiver (6) by period introducing means (18) in the reconstructed sequence of signal samples, the interpolation error may be reducedconsiderably.

Title: Cross-linked amylose material for enzymatically controlled drug release
Inventor: MATEESCU MIRCEA A
IPC: A61K9/22
Filed: 1993-07-22
Abstract: The present application is concerned with a solid slow release pharmaceutical dosage unit. More specifically, the invention is directed to a tablet form prepared by direct compression of cross-linked amylose (CLA) having a definite cross-linking degree, (alpha)-amylase and a pharmaceutical agent. The presence of the cross-linked amylose allows a sustained release of the drug, while the (alpha)-amylase permits the modulation of the release time. In other words, the release time of the drug is function of the amount of (alpha)-amylase in the tablet. The amount of (alpha)-amylase is defined in terms of Enzyme Units.

Patent CA-2148820-A1 (CA)
Title: Method and apparatus for automatic configuration of a network connection
Inventor: WEBBER HAROLD H
IPC: H04L12/46
Filed: 1993-12-01
Abstract: 2148820 9413072 PCTABScor01 The present invention provides automatic configuration of the transmit and receive paths of a network connection, preferably a 10 Base-T 5 network connection. It senses which pair in a cable is used for TX signals (430A, 438A) and which is used for RX signals (430B, 438B) then it automatically swaps or unswaps the RX and TX  pairs of the port so that a connection is made regardless of whether a crossover (434) or straight-through cable (432, 436) is used. The invention uses link integrity pulses, which are used to periodically test the integrity of the network, to determine which pair is for reception and which is for transmission. Since the auto-crossover transceiver has line receivers and line drivers connected to both pairs of the cable, once it determines which pair is TX and which is RX, it selects the appropriate line receiver and driver to match the cable configuration. The present invention allows connection to a network where another node on the network is either of the standard "hub" type, of the standard "MAU"  type, or of the auto-crossover type.

Patent CA-2149671-A1 (CA)
Title: Multi-dimensional signal processing and display
Inventor: HUTSON WILLIAM H
IPC: G01S11/14
Filed: 1993-03-02
Abstract: A multi-dimensional acoustic data processing and display system arranges acoustic data in a three-dimensional matrix. The three-dimensional matrix is compressed (81) using singular value decomposition into singular vectors and singular values. A historical database is created and maintained and is also concatenated with the three-dimensional data. This database allows reverberation and noise to be diminished and other, weaker features in the data to be enhanced (82). Once the data is compressed, the data can be analyzed efficiently. The singular vectors are partitioned into one or more groups on the basis of their singular values or other criteria. Certain of the compressed data elements are enhanced or diminished by modifying the singular values within each of the groups of singular vectors. Selected singular vectors are processed further by other techniques for further enhancement, detection, isolation, feature extraction and classification. The compressed and enhanced data is then expanded (83) back into three-dimensional form for display (84).

Title: Method of polarizing acoustic fields in particular with the aim of achieving an extrelmely broad, non-localized and spatial stereo effect requiring little space
Inventor: KEHLER WALDEMAR
IPC: H04R5/02
Filed: 1993-12-29
Abstract: Described is a process for the generation of polarized acoustic fields: By way of directivity, an unusually broad, spatial stereo effect is created in an extremely large listening area, even with very small monolithic systems. The ability (internal structure, geometry, surface, resonance) of bodies (acoustic "conductors", including "insulators" or "reflectors") to form at least one preferred spatial direction is utilized (polarization). It appears that the acoustic 3-D space on the recording side can be reproduced in an equiphased manner with process-conforming sound transformers, already largely without electronic aids. However, the latter, in the form of propagation time elements or active frequency or phase response smoothers, favorably compensates for system-specific peculiarities.
