Abstract: Disclosed is a system and method for improving efficiency and overall capacity of data transmission within a given bandwidth in a GPRS/EDGE wireless air-link channel. A GPRS data terminal, mobile unit and/or other end-user equipment is equipped with a (specially designed) Trellis coder that replaces the traditional cyclic coder and allows encoding and decoding of data via the Trellis code algorithm. Trellis coder eliminates errors in data transmission, increases capacity in a given bandwidth, and corrects problems with fading channels associated with wireless transmission. The Trellis coder is also utilized for voice transmission and may be fabricated on an integrated circuit for utilization within hand-held devices.

Abstract: A method and apparatus for the indentification of corrosion in a metal object is disclosed. The method comprises analyzing the statistical distribution of signals generated between two electrodes, typically exposed to the same corrosion conditions as the metal object, and preferably analyzes the skewness and kurtosis of the signals. Neural nets are preferably used in the analysis.

Abstract: A jamming suppression system which includes a plurality of receivers for receiving electromagnetic radiations and a separate notch filter coupled to each receiver for filtering selected frequencies from electromagnetic radiations received by each of the receivers. In accordance with one embodiment of the invention, a spatial combiner responsive to the outputs of each of the notch filters extracts essentially jam-free information from the electromagnetic radiations. In accordance with a second embodiment of the invention, a plurality of spatial combiners, each responsive to the outputs of each of the notch filters, extracts essentially jam-free information from the electromagnetic radiations. The notch filters are adaptive notch filters for on-line selection of their filtering action. One of the notch filters is a master filter and the remainder of the notch filters are slave filters controlled by the master filter.

Abstract: A method and system are provided for indicating a change between a first image and a second image. In a first aspect, a sequence of images is sensed (304, 310) including the first and second image. The first image is previous in the sequence to the second image. Each image previous in the sequence to the second image is processed generating a first processed image (312). The first processed image and the second image are then processed generating a second processed image (316, 312). The first processed image and the second processed image are then processed generating an optical flow field (314). The optical flow field shows the change between the first image and the second image. In a second aspect, a first sequence of images including the first image is sensed (206). A second sequence of images including the second image is sensed (206). The first sequence is processed generating a first processed image (210). The second sequence is also processed generating a second processed image (208).

Abstract: A time-division switching system having a space-division network with a plurality of input terminals, each uniquely associated with a first buffer memory, and a plurality of output terminals, each uniquely associated with a second buffer memory, is disclosed. Time-shared communication paths through the space-division network are predominately completed such that digital data words representing signals from both parties to a conversation are transmitted through the space-division network during the same time slot. Normally, data words representing signals from telephone subscribers are assigned to first buffer memories in accordance with a fixed distribution plan. The system includes an arrangement which modifies the fixed distribution plan when it is determined that both parties to a conversation will have their data words stored in the same first buffer memory and switches data words representing signals from the called party of the conversation to an idle storage location in a different first buffer memory.
