Patent CA-2315026-A1 (CA)
Inventor: WIRTH WAYNE M
IPC: H01L21/304
Filed: 1998-05-04
Abstract: A method of selectively patterning a structured substrate without using a mask is disclosed. The method includes the steps of providing a surface having a plurality of protrusions, coating the surface with a filler material thick enough so that the protrusions are covered, and planarizing the filler coating. The filler material is thereafter partially removed in a uniform fashion to expose only those portions of the protrusions to be modified. After modifying the protrusions by, for example, deposition or etching, the remaining filler material may be removed, resulting in a structured substrate selectively modified or patterned at its protrusions.

Abstract: A method of performing synthetic aperture magnetometery on the signals from a target organ using an array of biomagnetic sensors positioned in a predetermined manner around the target organ, each sensor in the array having a position vector and an orientation vector relative to a common coordinate system encompassing the target organ. The method comprises the steps of: (i) simultaneously measuring EM signals from each sensor positioned in the array for a selected time interval; (ii) computing a covariance matrix of the measured EM signals over a user-selected time sub-interval within the selected time interval; (iii) selecting a set of coordinates for a region of interest to be imaged and a distance between voxels to form a grid of voxels; (iv) computing a forward solution for a current element at each of the voxels for each of the sensors in the array sensors; (v) computing an RMS current density estimate for each voxel from the covariance matrix and the forward solution for that voxel; and (vi) displaying the voxels estimating RMS current density as a first image. The method is particularly well suited for evaluating brain activity in a human subject.

Title: Humanized immunoglobulins and their production and use
Inventor: SELICK HAROLD E
IPC: C12N15/13
Filed: 1989-12-28
Abstract: Novel methods for designing humanized immunoglobulins having one or more complementarity determining regions (CDR's) from a donor immunoglobulin and a framework region from a human immunoglobulin comprising first comparing the framework or variable region amino acid sequence of the donor immunoglobulin to corresponding sequences in a collection of human immunoglobulin chains, and selecting as the human immunoglobulin one of the more homologous sequences from the collection. Each humanized immunoglobulin chain may comprise about 3 or more amino acids from the donor immunoglobulin in addition to the CDR's, usually at least one of which is immediately adjacent to a CDR in the donor immunoglobulin. The heavy and light chains may each be designed by using any one or all three additional position criteria. When combined into an intact antibody, the humanized immunoglobulins of the present invention will be substantially non-immunogenic in humans and retain substantially the same affinity as the donor immunoglobulin to the antigen, such as a protein or other compound containing an epitope.

Title: Detection of cancer using cellular autofluorescence
Inventor: BANERJEE BHASKAR
IPC: G01N33/50
Filed: 1998-08-25
Abstract: Apparatus and methods especially useful for detection of cancer using cellular autofluorescence are described. In one embodiment, an apparatus (10) includes a source (12) of white light which produces a beam of light transmitted to a tissue via one group (18) of optic fibers in a two-way fiber optic bundle (22). The two-way fiber optic bundle (22) may be passed through a conventional endoscope. The beam of light excites the tissue and results in an emission of cellular autofluorescence at a wavelength of about 330 nm. A light sample from the tissue is directed back through the two-way fiber optic bundle (22) and then passes through a photodetector (36). The photodetector (36) produces a signal, representative of the intensity of cellular autofluorescence, which can be passed to a monitor (38) as a wave form or meter response. The apparatus may further comprise a charge-coupled device and video imaging technology to produce real time video images of tissue being examined.

IPC: F16F1/50
Filed: 2001-02-23
Abstract: Vibration absorbers are provided which utilize a torsional spring and a dynamic mass to control vibrations that occur within the structure to which they are attached. Additionally, pipeline systems are provided which utilize such vibration absorbers including a mass and a torsional spring to control the vibrations that occur within the pipeline system. In various embodiments of the present invention, the torsional spring is one or more elastomer elements coupled between the dynamic mass and a support frame to produce a spring force responsive to pivotal rotation of the dynamic mass relative to the support frame. In various embodiments, one or more elastomer elements arranged in series or in parallel may be used as the torsional spring to provide a desired vibratory dampening characteristic for applications, such as pipelines. Use of such torsional springs may provide a more simplified design with less mechanical joints which may be less susceptible to failure in harsh environments.
