Title: Forward error correction for high speed optical transmission systems
Inventor: DOHMEN RALF
IPC: H04B10/556
Filed: 1999-07-26
Granted: 2004-03-23
Abstract: Memory requirements and processing delays associated with the application of forward error correction in high speed optical transmissions are substantially reduced by mapping a forward error correction code on a row-by-row basis into unused overhead bytes in a high bit rate signal frame. By applying the forward error correction code to an entire row of the signal frame on a row by row basis, approximately one row needs to be stored at a time thereby reducing the total memory requirements for forward error correction processing. Using SONET as an exemplary application, approximately 1/9th of the entire SONET frame (e.g., one of nine rows) needs to be buffered for forward error correction processing. In an illustrative embodiment, four forward error correction (FEC) blocks are provided for each row for a total of 36 FEC blocks for a frame. Each FEC block comprises four bytes of correction bits for a total of 32 correction bits.  These 32 correction bits are mapped to unused overhead and are used for correcting errors in one block of one row of a signal frame, wherein one block covers 1/4th of the row. Other unused overhead bytes in the row can be used to carry error detection codes for detecting multiple errors in a row to determine when forward error correction should be disabled. For example, if a single bit error correcting code is employed, then error correction can be disabled to avoid false corrections if more than one error is detected.

Abstract: A microwave filter (10) has first and second subfilters (18a-b). Each subfilter (18a-b) has at least one single mode resonator (12a-g) and a preset electrical response. The second subfilter (18b) is cascaded to the first subfilter (18a) by coupling one of the at least one single mode resonator (12a-c) of the first subfilter (18a) to one of the at least one single mode resonator (12d-g) of the second subfilter (18b). The microwave filter (10) has an overall transfer function dependent upon the selection of the first and second subfilters (I8a-b) from a plurality of subfilters having different preset electrical responses.

Abstract: Twin compartment packets, eg. tea bags, are formed with the compartments connected at the heads of the packet and optionally at the tails. The packets are produced from a pair of compartmented tubular webs that are brought together with the compartments in register, the webs then being interconnected at the compartment end seals and severed at those seals to form the separate packets. Apparatus for performing the process deposits doses of tea at spaced intervals onto the two separate webs before forming them into the tubular compartmented webs, brings the compartments of the two webs into register, interconnects the registered compartments, and separates the interconnected compartments into individual packets while the web advances continously through the apparatus. The process is capable of high production rates because the webs are able to move through the successive stages at a uniform speed.

Title: Security systems for inhibiting theft of goods from retail stores
Inventor: MARTIN ALFRED HENRY
IPC: G08B13/24
Filed: 1999-10-28
Granted: 2009-01-06
Abstract: A checkout system for a retail store is disclosed which comprises a bar code reader (10) and an anti-theft tag deactivator (14). The bar code reader produces a signal upon the bar code on an article being read successfully by the reader. This signal is used to enable the deactivator for a predetermined period of time whereafter the deactivator is disabled until the next successful bar code read. This minimises the prospects of a cashier being able to deactivate the anti-theft tag on an article without having read the bar code on the article and hence entered the sale. The system can also include a microswitch for detecting closing and opening of the cash drawer. If the drawer is left open, but the bar codes on articles are read by the bar code reader, this ca n indicate the possibility of goods being fraudulently removed from the store.
