Patent CA-2320575-A1 (CA)
Inventor: NADEAU JAMES G
IPC: C12Q1/68
Filed: 2000-09-25
Abstract: Signal primers are employed for detection of nucleic acid target sequences by fluorescence quenching mechanisms. The signal primer comprises a first and a second oligonucleotide and is partially single-stranded and partially double-stranded. In the presence of target, the. second oligonucleotide of the signal primer. is displaced from the first and a conformational change in a reporter probe occurs which changes the distance between the members of a donor/quencher dye pair linked to the reporter probe. The change in proximity between the dyes causes an increase or a decrease in fluorescence quenching, which is detected as an indication of the presence of the target sequence.

Patent CA-2324877-A1 (CA)
Inventor: OLSEN ROBERT GREGG
IPC: G06F13/14
Filed: 2000-10-31
Abstract: In a replicated component system, changing the condition of a component can deleteriously effect the system as a whole unless the result of making such a change may have on other components is considered. In response to a request to change the condition of a subject component to a specified condition, where the request is from a fixed set of request operations, the request is first validated using a particular validation algorithm associated with the request type. If the request is successfully validated (i.e., a determination is made using the validation algorithm that making the requested change will not negatively affect the system or components with which the subject component has a relationship), then the request is realized using a particular realization algorithm associated with the request type. Each validation algorithm and realization algorithm are from fixed sets of such algorithms that are associated with each possible request operation. Prior to effecting a change to any component in the system, the configuration controller is provided with information that includes the type of component that each component in the system is and the relationships that exist between components. Such relationships are also from a fixed set of possible relationships. This information is provided through a graphical user interface in which the attributes of each component type and the relationships between components are specified using dialog windows and a canvas window which visually displays representations of each component in the system and the relationships that exist between these components.

Title: Method and device for monitoring an electrode line of a bipolar high-voltage dc transmission system
Inventor: AMMON JORG
IPC: G01R31/50
Filed: 1999-04-16
Abstract: In order to monitor an electrode line, comprising two lines, of a bipolar HDT system, a balanced-to-earth pulse is fed from an unbalanced-to-earth pulse (u(t)) in push-pull mode into the lines, and an actual echo curve (EK) which is compared with a dynamic desired echo curve is recorded from the echo signals, a fault signal being generated upon overshooting of a tolerance band placed around the echo differential curve (EDK). The result is a monitoring method which is almost independent of the strongly fluctuating earth conductivity, which has a longer range in simultaneous conjunction with a lower dispersion of the echo, and which radiates less electromagnetic energy and requires no additional decoupling elements.

Abstract: A partitioned processing system is disclosed wherein a shared storage space is implemented between plural partitions running heterogeneous operating systems. The shared storage permits the partitions to inter operate at the process level. The shared storage includes a table with entries defining the rules governing how the partitions inter-operate through the shared storage. The table entries may be made by a stand-alone process running independent of the partitions, or via memory broker which may be implemented in a partition as an operating system extension. A memory client running in a partition may initiate the creation of the table entries by the memory broker. The inter-operation of the processes in the partitions may be governed by an extension of an inter process protocol known to both operating system images. Further implementations of the system include establishing a heterogeneous client server network within the system passing request and responses through the shared storage space.

Title: Optical characteristic measuring apparatus, the method thereof and recording medium
Inventor: YAMASHITA TOMOYU
IPC: G01M11/02
Filed: 2001-07-09
Abstract: The object of the present invention is to provide an apparatus that can perform measurement of chromatic dispersion, even if the wavelength of variable-wavelength light source and that of fixed-wavelength light source for reference are identical with each other.      The variable-wavelength light generated by a variable-wavelength light source 12 is subjected to intensity modulation to a frequency f by a first optical modulator 15a and transmitted from one end 30a to the other end 30b of an optical fiber 30. The fixed-wavelength light generated by a fixed-wavelength light source 14 is subjected to intensity modulation to a frequency f by a second optical modulator 15b and transmitted from the other end 30b to the one end 30a of optical fiber 30. Therefore, it is possible to separately obtain the variable-wavelength light and fixed-wavelength light transmitted through the optical fiber 30 using a second directional coupler 28 and a first directional coupler 26, respectively, regardless of wavelengths thereof. Accordingly, it is also possible to perform the comparison of phase and measurement of chromatic dispersion, even if the wavelengths of variable-wavelength light source and fixed-wavelength light source for reference are identical with each other.

Title: External flue heat exchangers
Inventor: FERRARO JOSEPH C
IPC: F24B9/00
Filed: 2002-01-11
Abstract: A heat exchanger is mounted external to a section of flue pipe or is an integral part of a section of flue pipe. The heat exchanger preheats a domestic hot water supply and boosts the return water temperature, prior to reentry to the furnace coil. The heat exchanger reduces fuel use, pollution and wear of the furnace and burner. A typical heat exchanger installation includes an oil or gas burner located on a furnace or boiler having a flue pipe leading to a gaseous outlet, such as a masonry chimney. A short vertical flue section leads to a draft-regulating damper. The flue heat exchanger may be a coil of tubing wrapped around flue section, such that the tubing picks up heat from the heated flue gasses. Preheated water exits from the heat exchanger.
