Filed: 1998-03-25
Abstract: A novel means and apparatus for a new kind of photography and videography is described. In particular, a wearable camera with viewfinder means is introduced. The system, in effect, absorbs and quantifies rays of light that are processed on a small wearable computer system and re-constituted to emerge to reconstruct the virtual image of objects at nearly the same position in space, or at a coordinate transformed position, as viewed by the wearer of the apparatus. The wearer of the apparatus becomes, after adaptation, an entity that seeks, without conscious thought or effort, an optimal point of vantage and camera orientation. Because of the wearer's ability to constantly see the world through the invention, which may also function as an image enhancement device, the apparatus behaves as a true extension of the wearer's mind and body, giving rise to a new genre of documentary video.
Patent CA-2310510-A1 (CA)
Title: Method for identifying and inhibiting functional nucleic acid molecules in cells
Inventor: ROBERTSON HUGH D
IPC: C12Q1/68
Filed: 1998-11-20
Abstract: Two methodologies are provided: the first provides a means for rapidly and efficiently identifying essential and functional genes; and the second provides a means for obtaining biologically active nucleic molecules (ribozymes, EGSs, and antisense) which can be used to inactivate functional genes. In the first method, a library of EGSs is prepared based on all possible known compositions. In a preferred embodiment, the EGSs are twelve or thirteen-mers for targeting bacterial RNAse to cleave a substrate. This library is added to the cells containing the genes to be screened, for example, E. coli. Those cells in which the EGS causes a loss of viability, or other phenotype, are identified. The EGS(s) responsible for the loss of viability are analyzed, and the resulting sequence information used to identify the gene within the known genomic sequences. In the second method, nucleotide molecules with optimal biological activity, for example, directing cleavage of a gene of interest by RNase P, are rapidly identified through the use of a vector including two reporter genes, the first in phase with the gene of interest, and the second as a control to verify that the vector is present in a cell or to aid in selection of cells containing the vector. Those cells where the gene of interest is cleaved by the functional oligonucleotide molecule can then be identified by reference to reporter gene 1. The responsible functional oligonucleotide molecules is then isolated and characterized. These methods provide powerful tools for identifying essential genes whose sequence is known only as part of a genome with unknown function, as well as means for identifying functional oligonucleotide molecules, useful as diagnostic reagents and therapeutics.
Patent CA-2310784-A1 (CA)
Title: Liner for a work machine body and method for manufacturing the same
Inventor: BURG WILLIAM L
IPC: B60P1/28
Filed: 2000-06-06
Abstract: A liner for a high-wear portion of a work machine body, such as a dump truck body, is formed by separating a unitary plate of wear material, such as steel, into separate plate sections. The plate sections are formed such that confronting plate sections have portions that interfit with each other.      Gaps or voids are left between the interfitting portions to define openings the liner from the top surface to the bottom surface thereof. The openings cause material ejected across the liner to tumble rather than slide, thereby reducing abrasive wear. By separating the plate and forming the liner in this manner, no scrap material is created, which reduces cost compared to known design. In addition, liners having a variety of different dimensions can be created from the same plate sections by varying the relative spacing between adjacent plate sections.

Filed: 1999-01-08
Abstract: Antifungals based on dolastatin 10 and four structural modifications thereof (herein "peptides") and methods of treating a host afflicted with a fungi-induced infection are herein described. In broth macrodilution assays, these peptides were fungicidal for ATCC strains and clinical isolates of Cryptococcus neoformans. Speficitity for C.  neoformans was also demonstrated in the solid-phase disk diffusion assay, and fungicidal activity confirmed in killing kinetics experiments. Broth macrodilution minimum inhibitory and minimum fungicidal concentrations for the most potent modification ranged from 0.0975-1.56 µg/ml, and 0.0975-6.24 µg/ml, respectively. The minimum inhibitory concentrations were nearly identical in the presence of human serum, but increased with lowered pH. Suitable dosage forms for use of the novel antifungals are also described.

Title: High intensity focused ultrasound system for scanning and treating tumors
Inventor: BAI JIN
IPC: A61B8/08
Filed: 1998-12-18
Abstract: A high intensity focused ultrasound system for scanning and treating tumor, comprising a combined probe, a power source, a B-mode ultrasound scanner, a multi-dimensional digit-controlled motional apparatus, a vacuum degassor apparatus, a therapeutic bed, and a computer. The combined probe comprises a B- mode ultrasound probe and a therapeutic head which generates therapeutic focused ultrasound;  its ultrasound-emitting end is mounted on the multi-dimensional motional apparatus, and the motional apparatus carries out scanning movement outside the body under the control of the computer, causing the high sound intensity focal region (space-point) generated by the therapeutic head to carry out scanning movement within the body. By the action of high sound intensity, the temperature of the tissues in the focal region instantaneously rises to over 70 degrees centigrade and the tissues are affected by the mechanical action of cavitation, so degeneration and necrosis occur. In this way the tumor within the body is treated by means of the scanning outside the body.
