Abstract: The invention relates to a method and a device for distance measuring between two stations (A1, B1) connected by means of a communication channel. The method is based on a command structure, wherein the satellite (A1, B1), by means of which a distance is to be determined, sends a range request (3) via an inter-satellite communication channel to the other satellite (A1 or B1), which thereupon acknowledges this range request (3) with an answer (4). The distance is determined from the corresponding measurement of the cycle time. The range request (3) and the corresponding answer (4) are transmitted in a multiplexed communication channel.

Title: Power steering gear valve
Inventor: THOMAS ANDREW DONALD
IPC: B62D5/083
Filed: 1996-05-03
Granted: 2005-08-09
Abstract: A rotary valve for a hydraulic power steering gear has a sleeve with slots journalled to an input-shaft with grooves, the co-acting sleeve slots and input-shaft grooves defining axially extending orifices. The orifices are ported as a network such that they form primary (29) and secondary (30) hydraulic Wheatstone bridges arranged in parallel, each bridge comprising two limbs each of which communicates inlet and return orifices to respective inlet and return ports of the valve. The limbs of the primary bridge hydraulically communicate to a respective one of the cylinder ports (4, 5) at an interconnection point of the respective inlet and return orifices in that limb. The secondary bridge limbs do not hydraulically communicate to the cylinder ports. Hydraulic flow from the primary and secondary bridges is hydraulically communicated to the return port via respective primary and secondary return paths. The secondary return path has an annular restriction (71) having a cross section to flow which has a high aspect ratio.

Patent CA-2238069-C (CA)

IPC: H03H21/00
Filed: 1996-11-22
Granted: 2004-01-27
Abstract: A decoder capable of decoding audio signals encoded using analog noise reduction techniques, particularly Dolby A, is implemented by means of digital signal processing. The encoded signal passes through one or more digital filters, producing the decoded signal. The decoded signal is fed back to drive control blocks, which determine the parameters of the digital filters. The determination of these parameters may be arranged so as to emulate closely a given analog noise reduction decoder, such as a Dolby A decoder. The one or more digital filters are relocated to the feed-forward portion of the decoder - they are located in the feedback portion of the encoder when performed using analog techniques - to overcome the problems caused by delay introduced by the digital implementation which prevent a direct conversion of the analog decoder to a digital one.

Title: System and method for distributing information through cooperative communication network sites
Inventor: ROCHON DAVID A
IPC: G06Q30/02
Filed: 1998-09-08
Granted: 2003-03-18
Abstract: Information pertaining to products made by manufacturers and sold to consumers through retailers, is distributed to consumers through a communication network that connects consumer communication nodes to a cooperative network site having an accumulation of information about manufacturer product offers and retailer special deals. A consumer can obtain selected items of this information without knowledge of how to reach the cooperative network site, by simply logging in to a manufacturer network site or to a retailer network site. At a manufacturer site, the consumer can obtain a list of local retailers carrying the manufacturer offers and can then select from among the offers and receive complete details of the selected offers. At a retailer site, the consumer can obtain a list of manufacturer offers available at the retailer stores in the consumer's area, and can then select from among the available offers and receive their complete details. An additional feature of the invention makes use of a consumer "personal page," which is an individualized database in which consumer shopping preferences are defined, both by information that the consumer expressly provides and by the consumer's past shopping activity. Use of the personal page allows the consumer to receive product offers that are more targeted to the individual consumer, thus saving the consumer time and effort. Another embodiment of the invention provides for distribution of a product purchase incentive directly to the consumer in response to his or her selection of an advertising banner displayed on an independent commercial network site.

Abstract: L'invention concerne un système et un procédé de communication de bits de données, le procédé consistant à créer des bits de détection d'erreurs et à les répandre à l'intérieur d'une séquence de bits de données devant être transmis, afin de fournir un message à transmettre. Les bits de données répandus peuvent être dépendants des bits de données ou définis comme étant indépendants des bits de données. Le message à transmettre, qui est en codage convolutionnel, est transmis par l'intermédiaire d'un moyen de communication. Le message reçu est décodé en convolution par un décodeur convolutionnel qui est connecté de façon à être exploitable à un circuit logique d'indication d'erreurs. Les bits de détection d'erreurs répandus peuvent servir à détecter une erreur non corrigée dans la transmission ou à forcer le décodage convolutionnel afin de permettre une meilleure opération de la correction d'erreurs, sur la base des valeurs qui ont été définies pour les bits de détection d'erreurs répandus.

Title: Surface densification of machine components made by powder metallurgy
Inventor: GRAY MICHAEL S
IPC: C21D9/32
Filed: 1997-10-15
Granted: 2002-10-01
Abstract: A sintered powder metal part is surface densified by surface heating followed by repressing. Surface heating is preferably done to a temperature which is just below the critical temperature where the steel alloy material of the part transforms from a ferritic to an austenitic microstructure. Repressing is in a die set which is smaller than the part by 10 % of the surface heated depth. The hot skin is compressed and densified between the die and the cooler, and therefore less malleable core of the part. Following surface densification, the part may be resintered and/or heat treated.
