Patent CA-2228182-C (CA)
Inventor: VOLGYESI GEORGE
IPC: A61M11/06
Filed: 1998-01-26
Granted: 2007-03-20
Abstract: A breath-powered inhalation device is disclosed comprising a hollow cylindrical body having an air inlet at one end and an air outlet at another end. The air outlet is narrowed so that air velocity increases as air moves through the outlet. At the air outlet is positioned a releasing mechanism which preferably comprises a fibre tip impregnated with a medicament or the like. As the air rushes past the releasing mechanism, the medicament or the like is atomized and carried into the respiratory tract of the user by the air. The breath-powered inhalation device of the present invention provides advantages over conventional inhalation devices using compressed gases as propellants since it is more compact, simpler and does not require synchronization of activation of the device and inhalation by the user.

A front curved surface of the ocular lens is formed by effecting a cutting operation on the front convex surface of the lens blank whose back concave surface has been cut to form the back curved surface, while the lens blank is supported on a spindle of a front surface cutting device such that the back curved surface of the lens blank is drawn onto a holding surface of the spindle of the front surface cutting device under a negative pressure which is applied to the lens blank.
Patent CA-2244176-C (CA)
Title: Novel methods for the characterization of compounds which stimulate stf-1 expression in pancreatic islet cells
Inventor: SHARMA SEEMA
IPC: C12Q1/6897
Filed: 1997-01-22
Granted: 2008-07-15
Abstract: The present invention provides two embodiments. One is a method of testing for compounds which may induce STF-1 transcription. Pancreatic islet cells which express the STF-1/lacZ fusion gene are isolated and the effect of various compounds on STF-1 expression is measured by adding the compound of interest to STF-1/lacZ expressing cells. LacZ activity in control and treated cells is then quantitated by a colorimetric assay. Using this method, a large number of compounds can be screened and STF-1 inducing compounds can be identified readily. The other is a method of using the STF-1 promoter to mark insulin producing pancreatic islet cells in vivo. In this regard, the green fluorescent protein (GFP) served as an indicator. The introduction of the STF- 1-green fluorescent protein transgene into pigs allows for the efficient and rapid recovery of insulin producing cells from the pancreas.
Patent CA-2245244-C (CA)
Title: Tunable wavelength converter
Inventor: GLANCE BERNARD
IPC: H04B10/17
Filed: 1998-08-18
Granted: 2001-12-25
Abstract: A  tunable  wavelength  converter  generates  a selectable  wavelength  for  an  optical  signal.    The tunable wavelength converter includes an input  active section, an output active section, an interferometer and an optical wavelength selector.   The above components are integrated on a substrate between two mirrors. An optical  input  signal  at  a  first  wavelength  is  input through the input active section which in conjunction with the output section and the interferometer controls the  amplitude  of  an  optical  signal  at  a  second wavelength  propagating  in  the  laser  cavity.     The information  contained  in  the  amplitude  of  the  input signal  is  transferred  to  the  optical  signal  in  the interferomic  laser  cavity  and  output  by  the  output active section.   Thus,  the information of the optical input signal at the first wavelength is transferred to the optical output signal at the second wavelength.

Title: Il-9 receptor variants, useful in treating and diagnosing atopic allergies including asthma and related disorders
Inventor: LEVITT ROY CLIFFORD
IPC: C12N15/12
Filed: 1997-12-02
Granted: 2010-04-06
Abstract: This invention relates to the diagnosis, treatment and methods for discovery of new therapeutics for atopic asthma and related disorders based on variants of Asthma Associated Factor (2). One embodiment of the invention is a variant of AAF2, wherein codon 173 is deleted resulting in the loss of glutamine 173 from the mature protein precursor. This single amino acid deletion results in a non-functional AAF2 protein and therefore the presence of this phenotype should be associated with less evidence of atopic asthma. Correspondingly, the lack of susceptibility to an asthmatic, atopic phenotype is characterized by the loss of glutamine at codon 173. The invention includes isolated DNA molecules which are variants of the wild type sequence as well as the proteins encoded by such DNA and the use of such DNA molecules and expressed protein in the diagnosis and treatment of atopic asthma.

Abstract: An image data conversion processing device including an issue unit (8), plural line storing units (3) and a generating unit (4) for converting to a television signal image data stored in plural kinds of developing formats in a storing unit. The image data comprises plural lines, and the television signal comprises a predetermined number of lines. The issue unit issues a transmission instruction of image data to the storing unit in accordance with a period specified by a ratio of the line number of the image data to be converted and the line number of the television signal. The plural line storing units cyclically stores the image data transmitted from the storing unit line by line on the basis of the transmission instruction of the issue unit. In synchronism with the horizontal synchronizing signal of the television signal, the generating unit multiplies the image data stored in the line storing unit by an interpolative coefficient corresponding to the developing format of the image data to be converted in the plural interpolative coefficients which are beforehand set for the plural kinds of developing formats, thereby generating the television signal.

Title: Linear power control loop
Inventor: LOFSTAD ERIC W
IPC: G01R21/14
Filed: 2000-02-17
Granted: 2003-07-29
Abstract: The present invention presents a closed loop system that utilizes a non-linear reference to control a power amplifier's output power in order to obtain a linear transfer function of dB per adjustment step of a reference input. The closed loop system demonstrates that each non-linear stage/step in an automatic gain control system can create a linear closed loop system when using a non-linear reference. The closed loop system of the present invention eliminates the need for a linearization circuit for the system's power detector. The closed loop system may be used with most power amplifiers when linear control in terms of dB vs. adjustment setting of the input reference signal is desired. Output power in terms of dBms can be accurately set in linear steps where power control over a wide dynamic range is desired.
