Granted: 2004-08-24
Abstract: An apparatus and method for transmitting and receiving cryptographic information which provide a mechanism for resynchronization between a transmitter and receiver of the cryptographic information. A cryptographic synchronization counter at the transmitter generates a transmitter signature tag. A corresponding cryptographic synchronization counter at the receiver generates a receiver signature tag.  Information is ciphered and the transmitter signature tag is appended to the ciphered information. The ciphered information is received. The transmitter signature tag is compared to the receiver signature tag and the cipher text is decipher into plain text if the tags are equal. If the tags are not equal, the receiver crypto-sync counter is incremented and a new receiver signature tag is calculated to determine if the receiver is resynchronized (i.e., tags are equal) to the transmitter. If after a certain number of increments, resynchronization does not occur, a resynchronization procedure is initiated.

Title: Perceptual weighting device and method for efficient coding of wideband signals
Inventor: LEFEBVRE ROCH
IPC: G01L21/02
Filed: 1999-10-27
Granted: 2006-02-14
Abstract: A perceptual weighting device for producing a perceptually weighted signal i n response to a wideband signal comprises a signal preemphasis filter, a synthesis filter claculator, and a perceptual weightin g filter. The signal preemphasis filter enhances high frequency content of the wideband signal to thereby produce a preemphasised signal. Th e signal preemphasis filter has a transfer function of the form: p(z)-1 - .mu.z-1 wherein .mu. is a preemphasis factor having a value located between 0 and 1. The synthesis filter calculator is responsive to the preemphasised signal for producing synthesis filter coefficients. Finally, t he perceptual weighting filter processes the preemphasised signal in relation to the synthesis filter coefficients to produce the perceptually weighted signal. The perceptual weighting filter has a transfer function, with fixed denominator, of the form: W(z) A (z/.gamma.1) / (1- .gamma.2z-1) where 0 < .gamma.2 < .gamma.1 .ltoreq. and .gamma.1 and . gamma.2 are weighting control values, whereby weighting of the wideband signal in a format region is substantially decoupled from a spectral tilt of this wideband signal.

Abstract: A method for lining, rehabilitating, repairing, and rejuvenating pipelines and passageways is disclosed. The method comprises the steps of hauling a tubular liner (10) into a section of pipeline (14) to be repaired, disposing a reforming member (34) within the liner at one end proximate one end of the pipeline, depositing a cement slug (16) in the host pipeline proximate the said one end, and expanding the liner within the pipeline against the inner surface of the said pipeline by urging the reforming member along within the liner under pressure. The outer surface of the liner is provided with a plurality of protrusions (12) in the form of grout anchor hooks which penetrate the cement along the length of the said liner thus ensuring a mechanical bond between said liner and said cement. The cement also adheres to the inner surface of the pipeline and thus a rigid, secure, water impermeable lining construction is achieved. The anchor hooks both prevent gravitational slump of the mortar, and also ensure that the liner does not fall from the cement.  A substantially uniform thickness of cement is obtained, and the lining constructions adopts a substantially identical shape to that of the host pipe after the cement has hydrated.
