Patent CA-2350670-A1 (CA)
Inventor: FAY RALPH MICHAEL
IPC: E06B9/262
Filed: 2001-06-15
Abstract: An acoustic medium for temporary acoustic treatment of a room is formed from one or more continuous curtains, preferably, with pleated first and second major surfaces. Each pleated curtain preferably has one or more series of collapsible elongated tubular sections which form the pleats that make up the major surfaces of the curtain. Since the elongated tubular sections are collapsible, the curtain can be retracted by collapsing the elongated tubular sections and extended by opening the elongated tubular sections. The mat materials forming the elongated tubular sections and the pleated major surfaces of the curtain provide the curtain with an airflow resistance through the curtain, in a direction generally perpendicular to the planes containing the apexes of the pleats forming the first and second major surfaces of the curtain, that has the desired properties for absorbing or reflecting sound.

Patent CA-2351238-A1 (CA)
Title: A colorimetric method of manipulating inking in digital images
Inventor: WATKINS CHRISTOPHER L
IPC: H04N1/46
Filed: 2001-06-19
Abstract: The present invention proposes a method of digitally manipulating inking in digital images to optimize the image by affecting the amount of ink put on the paper. This is accomplished by replacing some inkings with values determined from actual measurement, rather than with values derived from formulas. Digital image data is manipulated by means of multiple transformations, maintaining printed color quality while obtaining a more favorable inking. The technique of the present invention of manipulating inking is colorimetric, in that it is based on precise color measurements. The method of the present invention is based on hard data for the particular print system.
Patent CA-2353164-A1 (CA)
Title: Rf communication with downhole equipment
Inventor: LAYTON JAMES E
IPC: E21B47/12
Filed: 2001-07-16
Abstract: Data or control signals are communicated over a three phase power cable supplying power from a surface location to a motor/pump assembly located within a wellbore utilizing modulated radio frequency signals. The radio frequency signals may be impressed on the power cable through physical taps to the power cable conductors or by reactive coupling to the power cable. The transmission frequency is selected from a range of frequencies which propagate through the motor windings and up the power cable with sufficient amplitude to be received and processed. The modulated RF signal may be transmitted concurrently with the three phase power on the power cable, and simultaneous bidirectional communications between the surface and downhole locations may be supported utilizing, for example, discrete frequencies for transmission in different directions. A network of RF transceivers or nodes may be situated at various locations along the wellbore and the motor/pump assembly to gather information about conditions at different points (e.g., below the motor/pump assembly, above the motor/pump assembly, and at the wellhead of a subsea borehole), with transmission on the power cable shared among the nodes through a spread spectrum and/or multiple access protocol.

Title: Method and system for frame and pointer alignment of sonet data channels
Inventor: CHER EDMUND
IPC: H04Q11/04
Filed: 2001-09-28
Abstract: One embodiment of the system for processing digital signals includes a pointer follower ("PF") to receive a first digital signal. The first digital signal can have a first embedded payload, a first signal frame and a first PF pointer. The first pointer follower can extract the first embedded payload and forward the first embedded payload to an elastic buffer. The elastic buffer is operable to receive, delay and forward the first embedded payload. Additionally, a pointer generator ("PG") is operable to receive the first embedded payload from the elastic buffer, construct a new digital signal comprising a new signal frame, a PG pointer and the first embedded payload.  The location of the new signal frame is determined by a synchronization pulse received from a synchronization module. In a further embodiment of the present invention, the delay imposed by the elastic buffer can depend upon the offset between the PG pointer and the PF pointer.

IPC: G01N35/10
Filed: 2001-10-09
Abstract: A hybrid valve apparatus for use with an aspiration actuator and a dispensing actuator to transfer fluid from a reservoir to a test site on a substrate surface.      The hybrid valve includes a valve assembly movable between an aspiration condition and a dispensing condition, and a manifold device coupled to the valve assembly. The manifold device includes a fluid aspiration conduit having a first aspiration port in fluid communication with the aspiration actuator.  On an opposite end of the aspiration conduit is a second aspiration port in selective fluid communication with the valve assembly to selectively aspirate a liquid sample slug from the reservoir into a discrete sample path when the valve assembly is in the aspiration condition. The manifold device further includes a fluid dispensing conduit having a first dispensing port in fluid communication with the dispensing actuator, and a second dispensing port in selective fluid communication with the valve assembly. When the valve assembly is in the dispensing condition, the sample path is fluidly coupled to the dispensing actuator to selectively dispense at least one droplet of the liquid sample slug therefrom, while simultaneously being out of fluid communication with the aspiration actuator. In contrast, in the aspiration condition, the sample path is in fluid communication with the aspiration actuator, while being out of fluid communication with the dispensing actuator.

Patent CA-2364407-A1 (CA)
Inventor: VAN NETTEN CHRISTIAAN
IPC: G01N1/24
Filed: 2001-12-05
Abstract: A self sealing fluid sampling apparatus includes a body with a filter therein and a fluid moving device, such as a fan, mounted therein for moving fluid through the filter. There is a fluid inlet communicating with the filter. There is also a fluid outlet communicating with the filter. A manually operable control simultaneously opens the fluid inlet and the fluid outlet and operates the fluid moving device for moving fluid from the fluid inlet, through the filter and out through the fluid outlet. For example, the body may be cylindrical and have a cylindrical shell rotatably mounted thereon. The shell and the body have fluid inlet openings and fluid outlet openings which are aligned when the shell is rotated in one direction and become unaligned when the shell is rotated in an opposite direction thus sealing off the filter compartment from the outside environment. Rotation of the shell also closes a switch to operate the fluid moving device when the shell is rotated in the one direction. The fluid moving device includes a motor and an electrical power source mounted within the chamber in the body. The body has sealing means to seal the chamber from the fluid.

Abstract: On décrit un détecteur de fumée photoélectrique, qui comprend un émetteur d'énergie rayonnante à longueur d'onde courte (14). L'émetteur, une diode DEL ou laser, émet des fréquences de l'ordre de 430 à 450 nanomètres.

L'énergie rayonnante émise à partir du matériau présente une longueur d'onde de l'ordre de soixante pour cent de l'énergie rayonnante incidente (14'). L'énergie à longueur d'onde courte est diffusée par une matière particulaire aéroportée caractéristique des feux flambants relativement rapides. L'émetteur, une diode LED ou laser, présente une longueur d'onde de 880 ou 940 nm couplée à des plages de longueur d'onde plus courtes (190-450 nm) avec détection associée. Il peut également détecter des feux couvants à combustion lente. Un circuit de commande et un dispositif de sortie audible produisent une alarme sonore locale lorsqu'ils détectent un feu.

Title: Corticotropin releasing factor receptor 2 deficient mice and uses thereof
Inventor: BALE TRACY L
IPC: A01K67/027
Filed: 2000-07-14
Abstract: The present invention provides transgenic mice deficient in corticotropin releasing factor receptor 2. CRFR2 mutant mice are hypersensitive to stress, and display increased anxiety-like behavior. Mutant mice had normal basal feeding and weight gain, but exhibited decreased food intake following food deprivation. Intravenous UCN has no effect on the mutant mice, but causes decreased arterial pressure in control animals. Deficiency in CRFR2 results in a significant increase in urocortin mRNA in the rostral region of the Edinger Westphal, and a significant increase in CRF mRNA in the central nucleus of the amygdala. These results demonstrate that CRFR2 mutant mice, as opposed to CRFR1 mutant mice, have an increased sensitivity to stress and display anxiety-like behavior.
