Title: Detection of nucleic acids by fluorescence quenching
Inventor: NADEAU JAMES G
IPC: C12Q1/68
Filed: 1998-05-21
Abstract: A detector oligonucleotide having a sequence which forms an intramolecularly base-paired secondary structure is described for use in detecting nucleic acid target sequences and target sequence amplification. The detector oligonucleotide is further modified by linkage to two dyes which form a donor/acceptor dye pair. The two dyes are positioned on the detector oligonucleotide such that they are in close spatial proximity in the base-paired, folded secondary structure, thereby causing quenching of donor fluorescence. The detector oligonucleotide may optionally further comprise a restriction endonuclease recognition site (RERS) which remains partially or entirely single-stranded in the base-paired secondary structure. The RERS is flanked by the two dyes. In the presence of target, the base-paired secondary structure is unfolded or linearized, increasing the distance between the donor and acceptor dyes and causing a change in fluorescence of the donor and/or the acceptor. If an RERS is present, it is rendered double-stranded in the presence of target, allowing cleavage or nicking by a restriction endonuclease and separation of the two dyes onto separate nucleic acid fragments. This may further contribute to the magnitude of the change in fluorescence.

Title: Method and apparatus for enhancing call set-up and handoff quality
Inventor: GUIMONT VINCENT
IPC: H04W36/08
Filed: 1997-02-26
Abstract: In a cellular telephone system (10), mobile station (16) measurements of received signal strength on each reference frequency are made in order to select a cell (12). At call set-up in or handoff to that cell, a voice frequency is selected (64, 102) by the system to carry the communication. A determination is then made as to whether the antenna used for the reference frequency is the same as that used by the selected voice frequency (66, 104).      From this determination, actions are taken as needed to address concerns over potential differences in broadcast coverage areas for the antennas.      For example, an alternate voice frequency (112) using the same antenna as the reference frequency may be chosen. Further, a test broadcast (120) may be made on the selected voice frequency for comparison to the received signal strength on the reference frequency in order to confirm (126) the selection of the cell and use of the selected voice frequency.

Title: Apparatus and method for spraying herbicide on weeds in a cotton field
Inventor: BECK JAMES L
IPC: G01J1/44
Filed: 1997-04-01
Abstract: Weeds (100) growing around the bases of the stalks of cotton plant (101) growing in a row (105 and 105A) in a cotton field are sprayed with herbicide without spraying the cotton stalks (101) or wasting herbicide on bare ground (107). The cotton plants are adequately mature that their stalks exhibit a significantly different spectral reflectance characteristic than the weeds typically growing amid the cotton. The cotton plants are adequately tall that the majority of the leaves of the cotton plants are disposed outside the area which can be sprayed using an electronically-controlled valve and nozzle (103). Light is transmitted toward an object (a cotton stalk, a weed, or soil) in the row and the reflected light is analyzed. If the object has a spectral characteristic of a growing weed, then the valve is activated and the object is sprayed with herbicide. If the object does not have the spectral characteristic of a growing weed, then the valve is not activated and the object is not sprayed with herbicide.
Patent CA-2251185-A1 (CA)
Inventor: CHOU MAU-SONG
IPC: B23K26/00
Filed: 1998-10-22
Abstract: A method and apparatus for monitoring the quality of a laser process such as a welding process comprises monitoring the light emitted from the weld plasma above the surface of the workpiece being irradiated by the laser beam.  The size of the plasma is determined from the light emission and compared to a predetermined value of the size as determined under process and workpiece conditions that produce welds of acceptable quality.  Variations of the monitored plasma size greater than a preselected value can represent unacceptable welds.  Such variations can be caused by changes in the laser beam power, the workpiece speed, laser focusing problems, insufficient shield gas flow, workpiece deformation and weld contamination.  The process monitors the light emission from a selected range of wavelengths that correspond to the major emission peaks of the light spectrum.  The process enables in-process control.

Title: Shape-memory, biodegradable and absorbable material
Inventor: SHIKINAMI YASUO
IPC: A61L31/00
Filed: 1998-11-12
Abstract: Shape-memory biodegradable and absorbable materials which make it possible to easily treat vital. tissues by suture, anastomosis, ligation, fixation, reconstitution, prosthesis, etc. without causing burn. These materials never induce halation in MRI or CT and never remain in vivo. Such a shape-memory biodegradable and absorbable material is a material made of a molded article of lactic acid-based polymer and can be recovered to the original shape without applying any external force thereto but heating to a definite temperature or above. It is obtained by deforming a molded article (a primary molded article) made of a lactic acid-based polymer and having a definite shape into another molded article (a secondary molded article) having another shape at a temperature higher than the glass transition temperature thereof but lower than the crystallization temperature thereof (or 100°C when the molded article has no crystallization temperature) and then fixing said molded article to the thus deformed shape by cooling it as such to a temperature lower than the glass transition temperature. When this material is heated to the above-mentioned deformation temperature or above, it is immediately recovered to the original shape. The lactic acid-based polymer is hydrolyzed and absorbed in vivo.

Title: Uridine-comprising therapeutic active agent for treatment of neurodegenerative disorders
Inventor: PIAZZA CINZIA
IPC: A61P25/00
Filed: 1997-05-23
Abstract: Uridine is a therapeutic agent active as a growth promoter for treatment of neuron degenerative diseases deriving from pathological ageing or selective destruction, in particular uridine shows the same biological effects of NGF, when added at low doses to the culture medium, so that uridine may replace NGF  as therapeutic agent in neural diseases and it may be also associated to other growth factors that allow neuron's differentiation, or with anti-cancer and anti-virus drugs that cause neuron damage. In addition uridine shows imporant trophic properties on various types of cultured cells, stimulating cell reproduction when used at rather high dose levels.
