Patent CA-2340150-A1 (CA)
Title: Methods and apparatus for mass spectrometry
Inventor: HOYES JOHN BRIAN
IPC: H01J49/10
Filed: 2001-03-09
Abstract: An improved method of parent ion scanning is disclosed. In one embodiment a quadrupole mass filter 3 upstream of a collision cell 4 is arranged to operate in a highpass mode. Parent ions transmitted by the mass filter 3 are fragmented in the collision cell 4 and detected by an orthogonal time of flight analyser 5 which obtains a daughter ion mass spectrum. Ions having a mass to charge ratio below the cutoff of the mass filter 3 are identified as daughter ions, and candidate parent ions may then be discovered and their identity confirmed by obtaining corresponding daughter ion spectra. In a second embodiment, the collision cell 4 alternates between high and low fragmentation and candidate parent ions can additionally be identified on the basis of the loss of a predetermined ion or neutral particle.

Title: Symbology imaging and reading apparatus and method
Inventor: VAN TASSELL JON E
IPC: H04N1/04
Filed: 1999-09-10
Abstract: Diffuse "dark field" illumination (90) and "bright field" illumination (162, 164) are each provided for a hand-held encoded symbology imager/reader; to be projected therefrom upon symbology disposed on a target (component part, goods, package, etc.). The imager/reader (30) is encased in a housing ergonomically configured to be gripped in more than one manner and to thus facilitate holding the imager/reader steady. The symbology to be imaged (40, 42, 44) is targeted by a line that not only spots the symbology, but by extending a length commensurate with that of the symbology, indicates that the symbology is in the field of view of the imager/reader. A CCD (252), disposed to receive light reflected from the symbology, has its readout controlled so that only selected portions of the CCD need to be analyzed for illumination and focusing purposes.   To optimize imaging and decoding time, and to optimize use of power, readout from some portions of the CCD is accomplished in relatively rapid time by speeding up the readout of the CCD in some of its active area; while reverting back to a slower readout for data to be analyzed for illumination and focusing control and decoding purposes. In addition, special application of entropy principles facilitate determining the optimum focus and illumination conditions for the imager/reader.

Title: Method and device for increasing efficiency of bioanalysis
Inventor: HILLER DONNA LEAH
IPC: G01N1/00
Filed: 2001-06-06
Abstract: Quantitative analysis speed can be increased at least four-fold via use of liquid phase flow segmentation. An analysis device such as a mass spectrometer 40 is supplied with a single continuous stream 100 consisting of individual segments made from four different chromatographic or flow injection testing streams by use of a timed valve or injector 10. The stream is formed of solution segments A-D of the different compounds, with the compound solution segments being separated by known fluid or solvent segments S. The nature of the individual solution segments is controlled by a high pressure valve which comprises correlated timing elements and selection elements for determining which compounds are being directed to the analysis device at any given time, for correlation to separate analysis results. The selection elements are, for example, perforations 1-5 in a rotating disc which are selectively aligned for a software-specified time, with stream sources of the different compounds and a conduit 21 leading to the analysis device or directly thereto.  A time correlated read-out matches results with specific compounds. Throughput of compounds for testing is multiplied to the physical handling limits of the analysis device.  For current mass spectrometers, at least four fold over conventional methods.
Patent CA-2351669-A1 (CA)
Inventor: PLAKSIN DANIEL
IPC: C12P21/08
Filed: 1999-11-02
Abstract: It is an object of the present invention to provide small antibody-derived recognition units for experimental, medical, and drug design purposes. A single-domain VH phage-displayed library that is based on a natural framewor k scaffold of a mouse monoclonal antibody with a unique VH/VL interface and a randomized CDR3 was generated. This library was displayed without any mutations or modifications in the original interface framework residues. The  library was used to select phage clones that bind specifically to protein antigens with affinity in the nanomolar range. The VH domains were subsequently produced as soluble proteins at very high yields by expressing them in E. Coli as insoluble inclusion bodies and in-vitro refolding. These small functional modules of antibodies were termed "Microbodies" and were fully characterized by means of biochemical and biophysical properties as we ll as binding properties to several antigens of interest.
