Title: Method of segmenting a pixelled image
Inventor: HONG QI HE
IPC: H04N5/275
Filed: 2000-01-06
Abstract: A technique is provided for segmenting a pixellated image (4) into foreground and background regions. The background and foreground regions of a preceding image are analysed (3) so as to provide noise and signal histograms. A first threshold is derived (24) as the lowest level such that a predetermined proportion of the background pixels have lower noise levels. A second threshold is derived (25) as the highest level such that a predetermined proportion of the foreground pixels have higher signal levels. A difference image is formed (5) as a difference between each pixel of the image (4) and the corresponding pixel of a non-occluded background image (1b). Each of the difference image pixels is allocated (11) as a background pixel if the value of the difference image pixel is less than the first threshold and the pixel is surrounded by a majority of neighbouring difference image pixels which are allocated to the background region. Each of the remaining pixels is then allocated (12) to the foreground region if its value is greater than the second threshold and it has a majority of neighbouring pixels which are allocated to the foreground region. The remaining pixels are then allocated (13) as candidate foreground or background pixels by comparison with a third threshold (26) which lies between the first and second thresholds. Each candidate pixel is then allocated as a background pixel if a majority of its neighbouring pixels are already allocated to the background region or are candidate background pixels. Otherwise, the pixel is allocated to the foreground.

Title: Span-based multi-sample Z-buffer pixel processing
Inventor: COSMAN MICHAEL
IPC: G06T15/40
Filed: 2000-01-07
Abstract: A method for creating a span-based Z-buffer pixel processor comprising the steps of assigning a span to be a group of related pixels, receiving polygon fragments in each span, determining which fragments are visible in each span and storing the visible fragments in each span to the frame buffer for rendering into a video display. Preferably each new fragment received is compared with all previously received fragments to determine which fragments are visible and all portion that are hidden are erased. If at any point there is too little space in the frame buffer to store the required data pairs of fragments may be merged to reduce the amount of memory space needed.

Title: Pinch preventing mechanism for a collapsible chair
Inventor: HUANG MING-TAI
IPC: A47C4/20
Filed: 2000-04-25
Abstract: A collapsible chair comprises a backrest frame 14, a seat frame 13, armrests 15, front legs 11 and rear legs 12. Locking mechanism 20 includes a pin 27 fixed to one of the rear legs, a sleeve 21 slidably mounted on the same leg and an engaging device 30. Pin 27 extends into compartment 29 of the sleeve and a spring 25 is mounted between the pin and the end wall of the compartment, biasing the sleeve downwards. Locking member 22 formed on the sleeve is therefore biased into engagement with the upper part 33 of the engaging device to lock the chair in its unfolded configuration. The engaging device 30, further comprises a notch 31, which engages with a wedge 212 formed on the sleeve 21. To unlock the chair prior to collapse the sleeve is moved upwardly along the chair leg, causes the wedge to slide along the notch, before disengaging it. Spring 25 will now bias the wedge into abutment with the top of the engaging device 30, allowing the sleeve to be released but maintained in an unlocked position. The chair can now be folded up, without the need to manually bias the locking sleeve upwards, reducing the risk of the user's fingers being trapped within the chair frame.

Title: Multiple links to versions of a source file in a distributed computer environment
Inventor: JONES JEFFREY ALLEN
IPC: G06F17/30
Filed: 2000-06-16
Abstract: Multiple links within a document (eg web page) to a source file (containing eg. a further document, an advertising banner) in a distributed computing environment (eg internet) facilitates auto synchronisation of distributed versions of a file and faster initial loading. Within a given document (eg. web page) at least two reference links (eg urls) are given for an embedded file. One link is directed to a preferred repository (eg fastest server), whilst the other link is to a master repository which contains an up to date version of the file. An application (eg browser) will check the local cache for a file matching the respective links if no such file is found an attempt to load the file from the preferred repository is made if this fails alternative repositories (if listed) and then the master repository are tried. If the file has been retrieved from any location bar the master repository the application, once idling, checks the version of the file against that held on the master repository. With this system Logos and advertisements may quickly be downloaded and displayed from a local cache or the preferred server and then checked at a latter time against those on master server.

IPC: H01L21/66
Filed: 2000-11-18
Abstract: A method is disclosed for evaluating an anisotropic etch in a microstructure. First a film 22 is formed on a substate silicon wafer 24. Next a series of holes 20 of progressively different area and having specific geometric shapes are formed through the film. An anisotropic etch is carried out in the microstructure through the holes by relying on different etch rates in different crystal planes under known and reproducible conditions. Finally, the microstructure is inspected through the holes after the anisotropic etch to compare results from holes of different area. The method is useful in the determination of etch depth.

Title: A method of estimating the carrier frequency of a phase-modulated signal
Inventor: ALCOCK ROBERT DAVID
IPC: H04L27/00
Filed: 2002-02-12
Abstract: A method of estimating the carrier frequency of a phase modulated signal involves estimating the error in an initial estimate of the carrier frequency of a pulse train and then using this error to generate a more accurate estimate of the carrier frequency. These steps are repeated via a recursive algorithm until a sufficiently accurate estimate is achieved. The error is estimated by mixing down to baseband (0 Hz) via subtraction of the initial carrier frequency estimate to give imaginary (I) and real (Q) quadrature data, calculating phase as a function of time, calculating mean phase, and phase-wrapping the data into a range equal to the size of the phase jump. The error is then found from the gradient of this graph. Figures 4-8 show the effect of these steps, which are summarised in figure 10. This iterative method requires knowledge of neither the previous sample's phase nor the number or position of the phase transitions, thus providing accurate carrier frequency estimates which are less susceptible to noise.

Title: Navigation system using mobile terminal
Inventor: KATOH SATOSHI

Title: HARQ system in which the output of a turbo coder is applied to a selected one of a plurality of puncturing patterns
Inventor: KIM MIN-GOO
IPC: H03M13/29
Filed: 2002-07-12
Abstract: Data of length L symbols is turbo coded to produce a 5L symbol output which is then punctured using one of a plurality of patterns (CO, C1, C2, C3). The applicant refers to the turbo coder output as a 'quasi-complementary turbo code' (QCTC). Each of the patterns select successive symbols from the turbo coder output. The punctured output is transmitted in a sub-packet. As shown in figure 12, the number of symbols in a sub-packet (i.e. the sub-packet length) depends on the pattern selected and on the data rate 1/L at the input to the turbo coder. The patterns are identified using 2 bit sub-packet identifiers (SPIDs). The punctured output may be passed through an interleaver or may be passed through a symbol repeater. The pattern CO is used for initial transmission. If a negative acknowledgment is received data must be re-transmitted. Pattern CO may be used for a first retransmission (chase combining technique) or alternatively patterns C1 or C2 may be used for a first retransmission (incremental redundancy technique). Table 5 shows inter alia SPID, data rate, and the sub-packet length L SC .
