Patent CA-2266715-A1 (CA)
Inventor: MASTERSON MARIA L
IPC: C08F12/22
Filed: 1997-09-30
Abstract: Cationically cureable adhesives and sealants with increased viscosities and improved rheological control and good storage stability are prepared using a cationically cureable monomer and a thickening polymer which is the alkylation reaction product of poly(4-hydroxystyrene) or poly(2-hydroxystyrene) with a compound RX where R is allyl, methallyl, crotyl or prenyl and X is Cl, Br or I. The cationically cureable monomer suitably includes at least one alkenyloxystyrene monomer. Such thickened adhesives are useful as edge sealants for flat panel display devices. A-stage curing of the adhesive with UV irradiation allows for near ambient temperature fixturing of the device assemblies and B-stage thermal curing of the adhesive can be conducted at much lower temperatures than are needed for glass frit sealants. The B-stage cured products have thermal resistance, outgassing and substrate adhesion properties adequate for flat panel display devices.

Patent CA-2278510-A1 (CA)
Inventor: LEMBKE TORBJOERN
IPC: F16C32/04
Filed: 1998-01-23
Abstract: Device for magnetic suspension of a rotor (10, 20, 30) in relative rotational movement along a predetermined rotation symmetric path with respect to a stator (14, 24, 26, 34, 36). Rotor (10, 20, 30) comprises a rotational body (11, 21, 31) which essentially consists of an electrically conductive unmagnetic material. Fitted at the stator (14, 24, 26, 34, 36) is at least one magnetic means (12, 22, 25, 32, 35), which comprises at least one rotation symmetric magnet (12, 22, 25, 32, 35) concentric with the rotational axis. The magnetic means is disposed to give rise to a rotation symmetric magnetic field concentric with the rotational axis.

Title: Unequal error protection for digital broadcasting using channel classification
Inventor: SUNDBERG CARL-ERIK WILHELM
IPC: H04H20/00
Filed: 1999-07-29
Abstract: The invention provides methods and apparatus for processing information, e.g., audio, video or image information, for transmission in a communication system. In an illustrative embodiment, interference characteristics are determined for a set of n channels to be used to transmit audio information bits, where n is greater than or equal to two. The audio information bits are separated into n classes based on error sensitivity, for example, the impact of errors in particular audio data bits on perceived quality of an audio signal reconstructed from the transmission. The classes of bits are then assigned to the n channels such that the classes of bits having the greatest error sensitivity are transmitted over the channels which are the least susceptible to interference. The interference characteristics associated with the n channels can be determined by, for example, measuring interference levels for one or more of the channels, or obtaining information regarding known interference levels for one or more of the channels. The channels may correspond to different frequency bands, time slots, code division slots or any other type of channels. The invention can provide UEP  for different classes of audio information bits even in cases in which the same convolutional code, or the same complementary punctured pair convolutional (CPPC) code pair, is used to encode the classes. The assignment of the classes of bits to the channels, as well as the characteristics of the classes a.nd the channels, may be fixed or dynamic.

Title: Software implementation of modem on computer
Inventor: HOANG MINH
IPC: H04M11/06
Filed: 1998-02-24
Abstract: A software implementation of a modem, particularly designed to execute on a general purpose host processor (102), controlled by a non-real-time, multi-tasking operating system (OS), such as the Windows 95 OS. The software modem is scalable and portable. In this fashion, communications protocols (particularly datapumps) may be easily added to, or removed from, the system, and the modem may be easily adapted for use on other types of processors and operating systems. The controller and datapump portions execute as a plurality of interacting subsystems, each of which can execute at least one of several priority levels. A HRT level routine is responsible for handling an ASIC (106) that buffers transmit and receive samples destined to and received from the phone lines (116). A SRT level task includes logic that needs time functionality, but which is not time critical like the HRT logic. BRT routines execute in an event-driven basis and are used for many controller functions.
Patent CA-2290786-A1 (CA)
Title: A method and system for distributed caching, prefetching and replication
Inventor: HEDDAYA ABDELSALAM A
IPC: G06F17/30
Filed: 1998-05-15
Abstract: A technique for automatic, transparent, distributed, scalable and robust caching, prefetching, and replication in a computer network that request messages for a particular document follow paths from the clients to a home server that form a routing graph. Client request messages are routed up the graph towards the home server as would normally occur in the absence of caching. However, cache servers are located along the route, and may intercept requests if they can be serviced. In order to be able to service requests in this manner without departing from standard network protocols, the cache server needs to be able to insert a packet filter into the router associated with it, and needs also to proxy for the homer server from the perspective of the client. Cache servers may cooperate to service client requests by caching and discarding documents based on its local load, the load on its neighboring caches, attached communication path load, and on document popularity. The cache servers can also implement security schemes and other document transformation features.

Title: Efficient implementation of typed view hierarchies for ordbms
Inventor: PIRAHESH MIR HAMID
IPC: G06F17/30
Filed: 2000-06-02
Abstract: A method for typed view hierarchies for an object-relational database management (ORDBMS). The views in the hierarchy are merged into a unified hierarchy view through case expressions for mapping and wrapping of overloaded columns. During the merge, the underlying logical tables are eliminated which results in a simplified query graph. The transformation is a non-loss operation which condenses the type information within the case expressions. This allows update, delete and insert operations to be resolved on the query graph on a local level. Using query rewrite rules, the case expressions may be simplified further.
Patent CA-2311700-A1 (CA)
Title: Protective device for injection or aspiration needle
Inventor: ASBAGHI HOOMAN A
IPC: A61M5/158
Filed: 2000-06-15
Abstract: A protective device for injection or aspiration needles has a barrel piece telescopically slidable over an adapter sleeve mounted at one end to the luer coupling of the syringe or to a multisample collector. An injection needle is mounted within the adapter sleeve, projecting out through an opening in the opposite nose end of the barrel piece. An interposed spring urges the adapter sleeve and barrel piece apart towards a fully extended position. The barrel piece and adapter sleeve are latched together in a ready to use position with the needle partially protruding out from the barrel piece. As the syringe or multisampling system is advanced, the needle is extended out through the barrel piece end to allow penetration into the patient's body, and automatic unlatching is induced as penetration begins. As the needle is withdrawn from the patient, the spring causes the needle to be fully withdrawn within the barrel, and locking features engage preventing any axial movement to insure permanent enclosing of the needle within the barrel piece and defeating any attempted reuse of the needle. A reference scale on the barrel piece aids in determining when the proper depth of penetration has been achieved.
