Title: A method for reading a two-dimensional barcode
Inventor: MA YUE
IPC: G06T7/00
Filed: 2000-05-24
Abstract: Horizontal and vertical edge count arrays are analysed to identify column and row centerlines therein to enable the subsequent reading of the binary data located at the intersection of each row centerline and column centerline. In a first embodiment, the centerlines are located by first locating each successive pair of peaks in the respective edge count array, where each peak must have a magnitude greater than a first predetermined value 140 and then locating a centerline in a valley region between each successive pair of peaks, each of the centerlines having a magnitude less than a second predetermined value. Preferably, each successive pair of peaks in the respective edge count array is separated by a third predetermined value. In addition, the first predetermined value 140 is preferably reduced by a predetermined amount if a second peak 165 within a pair of peaks in the respective edge count array is separated from a first peak 155 by more than a fourth predetermined value, and the second peak is then re-identified using the reduced first predetermined value 160. A second embodiment alternatively employs the method of the first embodiment or a prior art method to reduce the number of errors produced, using the prior art method first to locate the column centerlines and the method of the first embodiment to locate the row centerlines.

Title: Multi-bin assembly for recycling waste
Inventor: BLACK GRAEME
IPC: B65F1/00
Filed: 2000-07-19
Abstract: The system consists of four or five individual bins that can be connected together to form one waste bin. Each bin is designed for a specific type of waste, i.e. General Waste, Plastic, Cans, Glass and Paper. Each bin will be colour coded for easy identification, eg blue for cans. The bins will connect together by way of a tong-groove connection so they can fit together in any order. The Blue bin will be separated into compartments each capable of holding cans stacked on top of each other. All other bins will be the same size with open top. The bins can be collected on a trolley which will hold two sets of bins side by side and stack four high (8 total). The bins may be made of durable plastics able to be recycled. The system is particularly for use in an office, to facilitate recycling of segregated types of waste.

Title: Extraction and replacement of background signals in communication systems
Inventor: WESTLAKE STEPHEN JOHN
IPC: H04N7/14
Filed: 2000-07-19
Abstract: A communication system comprises a plurality of communication devices each of which may transmit signals to and receive signals from a selected one of the other devices. The signals may be audio or video signals. A background portion of the signal to be transmitted is removed (e.g. using chroma key if signal is video or a filter if the signal is audio) and is replaced by a selected signal representing a 'false' background. The 'false' background signal may be stored in the device, generated within the device, or supplied by an external source. The remaining main signal is transmitted along with the 'false' background signal, either together along the same communications channel after having been combined in the transmitting device, or transmitted separately along different channels. In the latter case, the combining is performed in the receiving device.

Title: Method for electromagnetic wavefield resolution
Inventor: AMUNDSEN LASSE
IPC: G01V1/00
Filed: 2002-05-24
Abstract: A method of determining the nature of strata beneath the seabed comprises applying an em wavefield to the strata and detecting an em wavefield response, and processing the detected response wavefield. The processing is done by resolving the detected wavefield into upgoing and downgoing components. The downgoing component represents reflections from the sea surface which causes interference, while the upgoing component represents reflections and refractions from subsea strata. The upgoing component is further analysed to derive the nature of the strata. The wavefield frequency is typically between 0.01 - 20 Hz.
