Patent CA-2241096-A1 (CA)
Inventor: HILL BRIAN R
IPC: G01D9/00
Filed: 1996-12-20
Abstract: A method and apparatus for recording sensor data (11-21). The analog and digital signals containing the sensor data (11-21) are accompanied by a concurrent analog video signal (22, 25). The analog signals are converted to digital form and highly redundant signals are compressed according to conventional compression techniques (36). The resulting compressed and uncompressed signals are encrypted and stored on a removable hard disk (30).  The data stored on the removable hard disk (30) can later be played back to reconstruct the original signals while assuring that the played back signals are correct reconstructions of the original signals. If desired, the data collected can be made a function of one or more of the sensors (11-21). Also, the data can be transmitted to a remote location or control signals can be received from a remote location.

Title: Using special ntsc receiver to detect when co-channel interfering ntsc signal accompanies a digital tv signal
Inventor: LIMBERG ALLEN LEROY
IPC: H04N5/44
Filed: 1998-06-23
Abstract: A method for detecting when a digital television signal is accompanied by co-channel interfering NTSC signal of substantial amplitude is described for use in a digital television receiver. The video portion of any co-channel interfering NTSC signal is synchrodyned to baseband, for generating an in-phase demodulation result including first artifacts of the digital television signal, and for generating aquadrature-phase  demodulation result including second artifacts of the digital television signal. The quadrature-phase demodulation results are phase shifted by 90° at frequencies in a prescribed frequency range before being linearly combined with the in-phase quadrature-phase demodulation results, to generate a linear combining result substantially free of the first and second artifacts of the digital television signal in the prescribed frequency range. An indication that the digital television signal is accompanied by co-channel interfering NTSC signal of substantial amplitude is generated by detecting whenever the amplitude of the linear combining result exceeds a prescribed value.

Patent CA-2255232-A1 (CA)
Inventor: MARCHIORI MICHELE
IPC: H03L7/085
Filed: 1998-12-15
Abstract: A method is described for the digital control of a phase-locked loop consisting in the separate estimation of both phase and frequency errors of the data source as compared with those of the local oscillator and in the separate and adaptive filtering of the two signals. The value of the VCO control voltage is calculated on the basis of the two filtered signals. The phase and frequency error estimation and the frequency and phase error filtering are carried out in such a way as to eliminate the time-varying random components (jitter and noise) without delaying the feedback signals, since the portion of the signals that varies with time because of the variation of the commands, is subtracted before estimations and filterings.

Title: Functionalized ferrocenyldiphosphines, a process for their preparation and their use
Inventor: PUGIN BENOIT
IPC: B01J31/22
Filed: 1997-07-09
Abstract: The invention relates to 1,2-ferrocenyldiphosphines which contain a functional group in the 1' position either directly or via a bridging group, and also a process for their preparation. The compounds are important ligands for transition metal complexes containing d-8 metals such as Rh, Ru, Pd or Ir.  These transition metal complexes are widely used in the hydrogenation of organic double or triple bonds, in particular olefinic double bonds and carbon-heteroatom double bonds. The complexes are particularly suitable for enantioselective hydrogenation using chiral ferrocenyldiphosphines and corresponding prochiral unsaturated compounds. Ferrocenyldiphosphines having a functional group in the 1' position are also important intermediates for ferrocenyldiphosphine ligands and their metal complexes of d-8 metals such as rhodium, ruthenium, palladium or iridium which are bound to inorganic or organic polymeric supports via this functional group. These metal complexes bound to an inorganic or organic support material are likewise very suitable for the hydrogenation of organic double or triple bonds.
Patent CA-2256937-A1 (CA)
Title: A distributed architecture and associated protocols for efficient quality of service-based route computation
Inventor: RABIE SAMEH A
IPC: H04L12/56
Filed: 1998-12-23
Abstract: In a packet switching network, a distributed architecture provides efficient computation of routes in Quality of Service (QoS)-based routing scenarios. Using a client-server model, only designated route servers store and maintain a databa se containing the entire network topology, so that each network node is not require d to store and maintain the network topology. Client nodes maintain a cache containing pre-computed routes so that they can often make routing decisions autonomously. A client contacts a designated route server only when the client cannot obtain from its local cache a route to a given destination that meets the performance requirements. A client cache may contain pre-computed routes with designated QoS profiles to all destinations or to a subset of destinations. Rout e servers may also contain caches, which may contain pre-computed routes to all destinations in the network with all QoS profiles, or may contain only a subset of such routes. Each client node may also be provided with intelligence to learn, maintain and adapt local information based on the statistical usage of the network. Clien t caches may learn statically, i.e, the cache contains routes based on a QoS profi le provided by the network service provider, or they may learn dynamically, i.e., routes are modified based on ongoing network usage statistics. The goal is to minimize the need to contact the route server as much as possible. Protocols are defined to maintain synchronization between the route server and its clients distributed across the network. These protocols need to be observed to ensure th at all nodes have the latest view of the network topology stored at the route serve r.

Abstract: A method, system and data structures for software development and execution includes a Run Time Event Manager and a set of Models. A Model is a type of data structure that contains no code but an ordered set of references to other Models, to Methods, or other Objects. Models are made accessible to the Run Time Event Manager by registering them upon satisfaction of a set of conditions. In one embodiment of the invention, the Run Time Events Manager is a fetch-execute loop implemented in code that, upon each loop, operates upon one of a set of Models, checks external I/O conditions and, subject to such conditions, may process different or Variant Models, rather than standard or Paradigm Models associated with default conditions.  Also, an Elastic Database may be implemented according to the invention that permits dynamically extensible database functionality.
