Patent CA-2217325-A1 (CA)
Title: Nucleic acid detection and amplification by chemical linkage of oligonucleotides
Inventor: SEGEV DAVID
IPC: C12Q1/68
Filed: 1996-04-30
Abstract: The invention is directed towards a method of amplifying target nucleic acids by using two oligonucleotide probe complement pairs.  Each member of the probe pair contains a chemical functionality group which permits linkage of the probes when the functionality groups are adjacent to one another following hybridization of the probe pairs to the template. One probe in each pair is composed of two regions, a first region which hybridizes to the target and which contains the chemical functionality group and a second, protecting region which prevents target independent joining as shown in the figure. The other probe in the pair contains the corresponding chemical functionality group. Upon joining of a first probe pair, an amplification can proceed in which the newly joined first probe pair can serve as a template for the second, complementary probe pair, which can in turn serve as a template for unjoined first probe pairs. This cyclic amplification is sensitive enough for a discriminative amplification of sequences which differ by merely a point mutation and therefore is suitable for point mutation detection and genotype determination as well as for the determination of the presence or absence of a specific nucleic acid in a sample.

Title: Method and apparatus for using an array of grating light valves to produce multicolor optical images
Inventor: HUIBERS ANDREW
IPC: B81B3/00
Filed: 1997-01-17
Abstract: A multicolor optical image-generating device comprised of an array of grating light valves (GLVs) organized to form light-modulating pixel units for spatially modulating incident rays of light. The pixel units are comprised of three subpixel components each including a plurality of elongated, equally spaced apart reflective grating elements arranged parallel to each other with their light-reflective surfaces also parallel to each other. Each subpixel component includes means for supporting the grating elements in relation to one another, and means for moving alternate elements relative to the other elements and between a first configuration wherein the component acts to reflect incident rays of light as a plane mirror, and a second configuration wherein the component diffracts the incident rays of light as they are reflected from the grating elements. The three subpixel components of each pixel unit are designed such that when red, green and blue light sources are trained on the array, colored light diffracted by particular subpixel components operating in the second configuration will be directed through a viewing aperture, and light simply reflected from particular subpixel components operating in the first configuration will not be directed through the viewing aperture.

Title: Marshaling and unmarshaling framework for supporting filters in a distributed object system
Inventor: JINDAL ANITA
IPC: G06F9/46
Filed: 1998-12-04
Abstract: In order to support filtering operations in a CORBA system, the marshaling and unmarshaling process is encapsulated in a server invocation object created from a class which contains data, including the request ID, the marshal buffer and the marshal and unmarshal methods. Filtering is supported by extending the class with a subclass that overrides the marshal and unmarshal methods to invoke the filters at the proper points. During operation, the CORBA object request broker examines the request to determine whether filtering is requested and instantiates a server invocation object either from the parent class, if filtering is not requested, or from the subclass, if filtering is requested.
