Patent CA-2164099-A1 (CA)
Title: A method of avoiding non-desired interference between services
Inventor: JANSSON RICKARD
IPC: H04Q3/00
Filed: 1994-06-01
Abstract: A method of avoiding undesirable between services in a telecommunication system that includes basic software (51) for a basic service and supplemental software for services supplemental to the basic service. The supplemental software is divided into action software (52) which acts solely on the basic service, and supplemental software (59) which acts on the remaining supplemental software. According to the invention, a supplemental service is represented by action elements. Combinations of action elements form nodes in a mathematical binomial tree. Only those combinations which correspond to interference, i.e. an undesirable behaviour, between supplemental services will form a number of structures, called interference event trees (55). Before a supplemental service can be executed, its action elements are compared with nodes in the interference event trees (55), with the intention of ascertaining whether or not the former coincide with action elements belonging to the nodes in the latter. Only those interference event nodes whose sets of action elements are equivalent with the set of action elements of the supplemental service or a set thereof are selected. An interference event node whose set of action elements is a subset of the action elements of a node that has already been chosen cannot be selected. Interaction software (58) belonging to selected nodes in the interference event trees is added to the basic software (51).

Title: Method and apparatus for providing scaleable compressed video signal
Inventor: KWOK WILSON
IPC: H04N7/26
Filed: 1994-06-17
Abstract: A compression/decompression system includes a source (10) of non-interlaced scanned video signal.      A preprocessor (12) constructs interlaced scanned video signal from the non-interlaced scanned video signal by selection of alternate lines of successive non-interlaced image signals.      The interlaced scanned video signal is compressed (14) according to known methods to generate primary compressed video data. The primary data is decompressed (22) by known processes, inverse to the compression processes, to regenerate the interlaced scanned frames. Interlaced scanned video signal, corresponding to the intervening lines of the non-interlaced scanned video signal, which were not included in the primary interlaced scanned video signal, is predicted (24) from the decompressed frames of video signal. In addition the intervening lines of the original non-interlaced scanned video signal, which were not included in the primary interlaced scanned video signal, are formed (20) into secondary interlaced scanned video signal. The secondary video signal is subtracted (26) from the predicted video signal to generate secondary field residues. These residues are compressed (30) by known methods to form compressed secondary video data. The primary and secondary compressed data are thereafter transmitted (18, 34; 40, 42) for reception by either interlaced scanned receivers or non-interlaced scanned receivers.

Abstract: The present invention relates to a support pillar system of a magnetic-shielded room. Each support pillar (10) of the support pillar system consists of a nested structure (11,12) composed of a first structure (11) and a second structure (12) there-around. The upper end of the first structure (11) is provided with a threaded part (13) and a member (18) provided with thread and disposed in the threaded part (13). The shield structure (25,26,27) of a magnetic-shielded room has been attached to the second structure (12) of the support pillar (10), whereby the floor (17) of the inner room is supported to the upper end of the first structure (11). When the member (18) provided with thread and disposed in the threaded part (13) is tightened in locking position, the member (18) provided with a thread locks the first structure (11) and the second structure (12) into one and same entity, whereby the vibration of the inner floor (17) is transmitted to the shield structure (25,26, 27) and the shield vibrates substantially in syncronization with the vibration of the floor (17) of the inner room. When the member (18) provided with a thread has been threaded into open position, the locking of the second structure (12) is re-leased, whereby the inner room is allowed to vibrate, irres-pective of the vibration of the other shield structures, and hence, the potential vibration of the inner room is not trans-mitted to the shield structures (25,26,27). <IMAGE>

Title: Apparatus and method for enhancing the security of negotiable documents
Inventor: SANDRU CALIN A
IPC: G07D7/0047
Filed: 1996-03-01
Abstract: The invention relates to an apparatus and method for enhancing the security of selected information associated with a negotiable document, such as the monetary value of a cheque. In the invention, one or more security features are printed or applied onto the cheque. One such security feature is an encrypted control code. The preferred embodiment employs a secret key cryptographic scheme to encrypt the monetary value and thereby generate a first control code which is printed on the cheque. When the cheque is presented for payment, a validator, such as bank or cheque clearing house, employs a verification system having a copy of the encryption key to read the monetary value from the cheque and re-encrypt it according to said scheme to generate a second control code. The cheque is not honoured if the first and second control codes are not identical. Another security feature is a security image, composed, for instance, from a foreground image of the monetary value superimposed over a background motif image. The security image has a number of hidden attributes, such as the relative aspect ratios, absolute and relative dimensions of the underlying foreground and background images, that are preselected and used when printing the security image. When the cheque is presented for payment a teller can visually inspect the security image for compliance with certain of the preselected attributes. The preferred validation system can also electronically scan the security image for the hidden attributes. This comparison makes it difficult for a forger to copy, for instance, the monetary value of the cheque and add a significant digit to it because some of the foregoing preselected image attributes are liable to change and be detected. The composite image serves as a back-up security when verification of the encrypted control code is not possible.

Title: Multipath search processor for a spread spectrum multiple access communication system
Inventor: EASTON KENNETH D
IPC: H04Q7/20
Filed: 1995-09-27
Abstract: An integrated search processor (128) used in a modem for a spread spectrum communications system buffers receive samples and utilizes a time sliced transform processor operating on successive offsets from the buffer. The search processor (128) autonomously steps through a search as configured by a microprocessor (136) specified search parameter set, which can include the group of antennas (112) to search over, the starting offset and width of the search window to search over, and the number of Walsh symbols to accumulate results at each offset. The search processor (128) calculates the correlation energy at each offset, and presents a summary report of the best paths found in the search to use for demodulation element reassignment. This reduces the searching process related workload of the microprocessor (136) and also reduces the modem costs by allowing a complete channel element modem (110) circuit to be produced in a single IC.
