Title: System for measuring the refractive index profile of optical components
Inventor: COCITO GIUSEPPE
IPC: G01N21/41
Filed: 1991-10-18
Granted: 1999-08-17
Abstract: A system for measuring the refractive index profile of optical components using a monochromatic radiation source and an acousto-optical modulator, which is driven by a periodically varying frequency. The modulator emits a first beam having the same wavelength as the source, and a second beam whose wavelength and emission direction vary with the modulating frequency. After the second beam has been collimated, radiation from both beams is directed towards a component under test and an electrical signal having varying frequency is generated representing of the beat between radiation from the two beams exiting from the component. A spectral analysis of the beat signal is performed, the refractive index value being derived from the position taken by the various frequencies of the beat signal on a detection plane.

Patent CA-2056456-C (CA)
Inventor: OUELLET LUC
IPC: H01L23/31
Filed: 1991-08-14
Granted: 2001-05-08
Abstract: A method of passivating a semiconductor device, comprises depositing a first dielectric passivation layer on the surface of the device, forming at least one planarization layer over the first passivation layer from an inorganic spin-on glass solution containing phosphorus and silicon organometallic molecules that are pre-reacted to form at least one Si~O~P bond between the phosphorus and silicon organometallic molecules, and subsequently depositing a second dielectric passivation layer on said at least one planarization layer(s). This results in improved step coverage of the underlying topography and permits much better protection against moisture related degradation than standard vapour phase deposited passivation layers even when the thickness of such layers is increased.

Title: Method for producing secretable glycosyltransferases and other golgi processing enzymes
Inventor: PAULSON JAMES C
IPC: C12N15/54
Filed: 1990-10-24
Granted: 2000-01-11
Abstract: A method for genetically engineering cells to produce soluble and secretable Golgi processing enzymes instead of naturally occurring membrane-bound enzymes. Cells are genetically engineered to express glycosyltransferases which lack both a membrane anchor and a retention signal. The resulting altered enzyme becomes soluble and secretable by the cell without losing its catalytic activity. Secretion of the soluble glycosyltransferase by the cell provides for increased production and simplified recovery of glycosyltransferase.

Title: Arrangement for controlling shared-buffer-memory overflow in a multi-priority environment
Inventor: PASHAN MARK A
IPC: H04L12/56
Filed: 1992-05-19
Granted: 1994-09-27
Abstract: ARRANGEMENT FOR CONTROLLING SHARED-BUFFER-MEMORY           OVERFLOW IN A MULTI-PRIORITY ENVIRONMENT Abstract A shared-buffer-memory-based ATM switching module (FIG. 1) used with ATM cells having a multiplicity of priorities has a plurality of queues (100) for each output port (O-N), one for each cell priority, and handles buffer overflow in a manner fair to all output ports. It initially allows output-port queues (100) tocompletely consume the buffer memory (12). Thereafter, when an additional incoming cell is received for which there is no room in the buffer memory, the lengths of all of the queues of each output port are individually summed (402) and compared to determine which port has the greatest number of buffered cells (406). A buffered ATM cell is discarded (410) from the lowest-priority non-empty queue of that port (408). The incoming cell is then stored in the memory space vacated by the discarded cell (412).

Title: Micromechanical accelerometer and method for the production thereof
Inventor: GESSNER THOMAS
IPC: G01P15/125
Filed: 1994-02-24
Granted: 1998-08-18
Abstract: The high precision micromechanical accelerometer is produced as a layered structure in particular from five semiconductor wafers which are insulated from one another by thin semiconductor material oxide layers. The coverplate and the baseplate (1, 5) are first connected by bonding to an associated insulating plate (2 and 4, respectively). Subsequently, counter-electrodes  (6, 7) fixed to the coverplate and to the baseplate, respectively,  are produced by anisotropic etching from the respective  insulating  plate,  said  counter-electrodes being contactable via contact windows (10 and 11, respectively) through the cover or baseplate. A central wafer (3) contains the unilaterally linked mass (14) (pendulum) produced also by anisotropic etching and serves at the same time as a movable central electrode of the differential capacitor. The layered structure comprising a five-layer structure is hermetically sealed by semi-conductor fusion bonding, e.g. under vacuum. Electrical contacting of the individual wafer layers is possible from the top in that by means of a stepped gradation of a marginal region of the individual wafers, contact pads (17-21) for each individual wafer can be attached.        A µB measuring device according to the present invention is characterized, above all, by extremely small leakage capacitances and by high temperature stability.

Abstract: To provide in situ hybridization assays in which the sex of a fetus, genetic characteristics or abnormalities, infectious agents or identification of other chemical, biochemical or genetic properties are detected by nucleic acid hybridization of fetal cells, such fetal cells, which circulate in maternal blood, are enriched, detected and interrogated. The techniques are capable of detecting a single genetic abnormality in a single cell, involving as few as approximately 75 base pairs, by visual microscopic ex-amination. Genetic abnormalities may include deletions, additions, amplifications, translocations or rearrangements. Multiple abnormalities may also be detected simultaneously, and they may be visually distinguished by color. Cells may be obtained from amniocentesis, chorionic villi sampling, or in vitro fertilization embryos or products of conception, but are preferably from mater-nal peripheral blood. Fetal cells such as lymphocytes, erythrocytes or trophoblasts may be enriched from maternal blood.  Eryth-rocytes may be enriched by removing maternal white blood cells with an immobilized antibody to a cell surface antigen, e.g.  CD45. Fetal cells may be enriched by density gradient centrifugation. Fetal cells are desirably distinguished from maternal cells by staining, e.g. with a labeled antibody to cytokeratin or to fetal hemoglobin of for fetal hemoglobin by hematoxylin/eosin, or by in situ hybridization to detect one or more fetal mRNAs, e.g., fetal hemoglobin or fetoprotein. Kits are provided for the disclosed procedures.
