Granted: 2003-08-19
Abstract: A digital video signal processing system includes apparatus for concealing errors which might occur in reproduced images due to image data lost during signal transmission. The system includes circuitry for detecting transmitted video data (20-24), gen-erating error signals if errors are present in segments (transport blocks) of the received data (25), and excising segments having errors from the data stream. The received data is applied to a decoder/decompressor system (26, 27) which decodes and decom-presses the transmitted video data according to a predetermined sequence. The decompressed video data may be applied to a memory (318) for subsequent display, recording, etc. The decompressor is responsive to the error signals for altering the predeter-mined sequence.
Patent CA-2125718-C (CA)
Inventor: DAGDEVIREN NURI RUHI
IPC: H04M11/00
Filed: 1994-06-13
Granted: 1999-03-16
Abstract: An approach for operating modems in synchronism with the A/D and D/A converters of the network limits the analog signals transmitted to the modem to low levels and concurrently restricts the received signals to large steps. This set of apparently conflicting signal limitations is achieved with a signal conversion process interposed in the communication path between the two hybrids. In one embodiment of this invention, the code conversion is implemented in an adjunct processor that is associated with a switch that participates in the communication path between the two modems. In operation, a call that needs the conversion process is identified by virtue of the calling party's number and service associated service provision information. When it is established that both the calling party's modem and the receiving party's modem operate in the manner that requires signal conversion, conversion is executed. Echo cancellation may be applied to the signal in the code conversion apparatus to further improve performance.

Title: Receiver for a direct sequence spread spectrum orthogonally encoded signal employing rake principle
Inventor: VITERBI AUDREY
IPC: H04B1/707
Filed: 1994-06-22
Granted: 1999-08-31
Abstract: A method and apparatus for decoding an orthogonally encoded data signal in a noncoherent receiver system. The method is referred to as dual-maxima metric generation. It comprises the steps of sequentially searching for a maximum energy level in each of two subsets of a given set of symbol indexes and associated energy levels and calculating a difference of the two values to form a soft decision output value. The two subsets are identified by the binary value (either "0" or "1") of a given digit of the binary equivalent of the symbol index. The soft decision output value reflects a measure of confidence of the value of the corresponding digit of the original signal. The dual-maxima generator (204) sequences through the steps one time for each binary digit of the original signal. The method allows the correlated energy from multiple receivers to be combined before the decoding of the signals, thus further reducing the complexity of the circuitry and improving the performance of the decoder.

Abstract: A system for relieving pressurized fluid entrapped in a annular space between a casing and the surrounding wall of a well bore hole during deployment of a packer exterior of the casing for sealing engagement with the wall.  When a packer is inflated in a zone where fluid is entrapped, such as an intermediate packer between two previously inflated packers, the squeeze pressure developed by the inflating packer has been found to be sufficient to prevent effective and lasting sealing of the intermediate packer.  The present system includes a valve mechanism which is activated by the pressurized fluid providing for inflating the packer to open a passageway to bleed the entrapped fluid into the casing and to then close the passageway as inflation of the intermediate packer is completed.

Title: Equipment for recognising when synthetic fibre cables are ripe for being discarded
Inventor: DE ANGELIS CLAUDIO
IPC: G01N21/89
Filed: 1996-02-13
Granted: 2005-07-12
Abstract: With this equipment, the ripeness for the discarding with synthetic fibre cables (5) for lifts can be ascertained. The principle of the recognition of ripeness for the discarding is based on the combination of two fibre types with different properties into one strand (18). The one fibre, the carrying aramide, has a high bending fatigue strength and a high specific elongation. The other fibre, a conductive carbon fibre (19) has a more brittle behaviour.      Both fibre types are twisted into one strand (18). In running operation, a carbon indicator fibre (19) will in every case tear or break, by reason of too great elongations or too great a number of bending cycles, earlier than the carrying aramide fibres of a strand (18). The number of the torn carbon indicator fibres (19) can be ascertained with the aid of a voltage source. In order that a remaining carrying capacity of the cable (5) can be assured, only a certain percentage of the carbon indicator fibres (19) may fail.      Then, the lift is automatically moved into a predetermined stopping place and switched off.
