Patent CA-2282586-A1 (CA)
Title: Determination of % glycated hemoglobin
Inventor: WESTERBERG DAVID A
IPC: G01N33/53
Filed: 1998-03-13
Abstract: A glycated hemoglobin assay utilizes a simple procedure for the determination of DCCT Standardized %GHb in whole blood samples. First, a lysed whole blood sample is incubated with a solid phase that is coupled with boronic acid or similar boronate compound through covalent linkage chemistries known in the art. Next, a labeled antibody to human hemoglobin is added and the resulting signal is directly proportional to the %GHb in the sample. The advantages of measuring %GHb using a single determination include high precision and, since the assay is easily automatable, high throughput. With automation, this assay can also be consolidated with other testing on one analyzer. The method according to the various embodiments of the invention thus eliminates the need for two measurements: one for GHb and another for total hemoglobin (THb).

Title: Detection d'interactions moleculaires par complementation de sous-unites de marquage
Inventor: MOHLER WILLIAM
IPC: G01N33/542
Filed: 1998-04-02
Abstract: Cette invention se rapporte à des procédés et à des compositions pour détecter des interactions moléculaires, en particulier des interactions entre protéines. Cette invention permet la détection de ces interactions dans des cellules vivantes ou in vitro. La détection d'interactions moléculaires dans des cellules vivantes n'est pas limitée à la région du noyau mais peut être effectuée dans le cytoplasme, à la surface de la cellule, dans les organelles ou entre ces entités. Dans un mode de réalisation, ledit procédé utilise des nouvelles compositions comprenant des protéines de fusion entre les molécules d'intérêt et au moins deux mutants de .beta.-galactosidase à faible complémentation inactifs. L'association entre les molécules d'intérêt amène les mutants de .beta.-galactosidase de complémentation à proximité les uns des autres, pour que la complémentation ait lieu et pour que la .beta.-galactosidase active soit produite. La .beta.-galactosidase active peut être détectée par des procédés bien connus. Parmi les utilisations de cette invention, on peut citer l'étude des interactions entre protéines, la génomique fonctionnelle, le criblage d'agonistes et d'antagonistes et la recherche de médicaments.
Patent CA-2286364-A1 (CA)
Inventor: DODSON JOHN STEVEN
IPC: G06F12/08
Filed: 1998-04-03
Abstract: A method of improving memory latency associated with a read-type operation in a multiprocessor computer system is disclosed. After a value (data or instruction) is loaded from system memory into at least two caches, the caches are marked as containing shared, unmodified copies of the value and, when a requesting processing unit issues a message indicating that it desires to read the value, a given one of the caches transmits a response indicating that the given cache can source the value. The response is transmitted in response to the cache snooping the message from an interconnect which is connected to the requesting processing unit. The response is detected by system logic and forwarded from the system logic to the requesting processing unit. The cache then sources the value to an interconnect which is connected to the requesting processing unit. The system memory detects the message and would normally source the value, but the response informs the memory device that the value is to be sourced by the cache instead. Since the cache latency can be much less than the memory latency, the read performance can be substantially improved with this new protocol.

Title: Multiple program unequal error protection for digital audio broadcasting and other applications
Inventor: SINHA DEEPEN
IPC: H04H20/00
Filed: 1999-12-21
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, the value of a single-bit or multiple-bit criticality flag is determined for each of the programs in abet of multiple programs to be transmitted in the system. The information bits for each of the programs are then separated into n classes, where n is greater than or equal to two, based on the values of the criticality flags for the programs. Each of the classes is provided with a different level of error protection, e.g., through the use of different convolutional codes or other suitable techniques. The program or programs having the highest criticality flag values in a given frame or other designated time interval thus have a larger percentage of their information bits assigned to the class that is provided with the highest level of error protection. The assignment of the multiple program bits to the classes, as well as the characteristics of the classes, may be fixed for a designated number of program frames, or dynamic, i.e., permitted to vary from frame to frame.

Title: Internet access for cellular networks
Inventor: WIDEGREN INA
IPC: H04L12/56
Filed: 1998-05-29
Abstract: A method and system are disclosed for use with a mobile radio network, which receives and analyzes packets from a packet-switched fixed network (101), such as the Internet, and depending on the type of information received (e.g., speech, low speed data, or high speed WWW data), routes the information over an appropriate radio air interface to a mobile radio terminal. The speech information can be routed to mobile radio terminals over a conventional circuit-switched mobile radio link (e.g., a GSM traffic channel) (113), the low speed data can be routed over a packet-switched mobile radio link (e.g., a GPRS traffic data channel) (114), and the high speed data can be routed over a wideband broadcast radio link (e.g., a DAB network radio link) (115).  As a result, mobile radio terminals can advantageously enjoy full access to the Internet and thereby communicate effectively over the Internet with other mobile and wirebound terminals.

Abstract: Conductive and weldable anti-corrosive compositions based on (blocked) polyurethane resins.  epoxy resins, together with curing agents containing nitrogen and conductive extenders are suitable for coating metal surfaces, in particular sheet steel in the coil coating process. These compositions are distinguished by a low stoving temperature, a distinct reduction in white rust on galvanised sheet steel in the salt spray test and by an improvement in the adhesion of the organic coating on the metallic substrate. These coatings furthermore also achieve adequate corrosion protection with a thin chromium coating, preferably also in Cr-free pretreatment processes. Sheet metal coated in this manner may be spot welded using any conventional processes.

Abstract: A method of and an arrangement for obtaining quality indicators for an objective assessment of a degraded or output video signal (11) with respect to a reference or input video signal (10). The strength of edges or signal transitions (12; 13) in both the input and the output video signals (10; 11) are calculated (14) providing input and output edge signals (15; 16). By processing (19; 21, 22) the edge signals (15; 16) introduced edges (23) and omitted edges (24) in the output edge signal (16) are established. For each of the luminance and chrominance signals of a colour video signal first and second quality indicators are obtained from normalized values of the introduced edges (23) and the omitted edges (24), relative to the output edge signal (23) and the input edge signal (24) normalized by first and second normalization factors, respectively. By using smeared Sobel filtering, correlation of calculated MOS and observed MOS by human test persons reaches a value of above 0.9.
