Patent CA-2240658-A1 (CA)
Inventor: THIBAULT SIMON
IPC: G02B26/10
Filed: 1998-06-15
Abstract: The present invention is directed to an optical system for measurement of a three dimensional device. The optical system is designed and configured to meet telecentric and f-.theta. requirements. The system employs primary and secondary mirrors operating in conjunction with a tertiary deflector mounted on a pivot. Light from a light source produces a beam which is deflected off the deflector and the secondary and primary reflectors respectively. The beam is then transmitted to the surface of the object to be measured. Deflection of the tertiary deflector on the pivot results in scanning of the light beam across the surface of the object to be measured.

Patent CA-2244931-A1 (CA)
Inventor: MCCOY ARCHIBALD H R
IPC: E02D29/14
Filed: 1998-08-12
Abstract: A frame and cover for road surface installations has a one-piece cast metal frame member with an aperture therein to receive a cover member which can be used for catch basins, maintenance holes, valve chamber covers and underground vaults. The frame member has a side wall which extends smoothly downwardly between the upper and lower faces of the frame member and is free from laterally outer projections. Vibrations from vehicles moving over the frame and cover are transferred downwardly to the structure on which the frame is supported rather than to the adjacent asphalt, thereby extending the service life of the asphalt surrounding the frame. The cover member preferably has at least one lug extending laterally outwardly from its outer wall, the lugs adapted to be received in corresponding recesses formed about the aperture of the frame member. The lugs and the recesses in the frame members are provided with holes to permit the frame member and cover member to be secured to one another by a mechanical fastener. The outwardly directed lugs on the cover member do not interfere with movement of personnel and equipment through the open aperture.

Title: Apparatus and method for blending and fabricating personalized lipstick
Inventor: SWAAB MARY
IPC: A61K8/00
Filed: 1998-08-25
Abstract: An apparatus and method for custom blending and fabricating lipstick to the specific demands of individual customers. The present invention provides a kit which enables a user to blend various pigments to arrive at a very specific shade, and then blend the desired shade with a specific base to result in a desired consistency of lipstick, and which also allows the blended bases and pigments to be heated to a liquefied form and poured into a mold for hardening.     Upon cooling and hardening, a conventional lipstick case can be attached to the lipstick for removal from the mold and use by the customer. The present invention therefore not only allows a user to quickly attain the specific shade and consistency of lipstick desired, but also eliminates the time consuming and unsatisfactory process of visiting multiple stores having expansive inventories of variously shaded and textured lipsticks.

Abstract: A method for forming a sol gel abrasive which comprises forming a gelled dispersion wherein the solids content in the dispersion comprises from 92 to 99 weight percent alumina or alumina precursor and 1 to 8 weight percent of a titanium oxide or titanium oxide precursor. The gelled dispersion is dried to form a dried gel and is heated to a temperature of from about 1225°C to about 1500°C.  The heating is done in a gas atmosphere in a reducing environment to create a reduced titanium oxide in the finished abrasive product. The temperature range for a ten minute heating time may be determined by the formula °C = 1425 ~75-20Tc where Tc is concentration of titanium oxide in weight percent solids. The product of the invention is a sol gel abrasive containing a reduced titanium oxide. The invention also includes the novel sol gel grain made by the method of the invention.

Title: Multiplexors with a flat top spectral channel shape
Inventor: DELISLE VINCENT
IPC: G02B6/34
Filed: 1999-03-18
Abstract: A multiplexing/demultiplexing optical circuit provides a demultiplexed output spectrum of channels having a flat amplitude response without sacrificing optical power. A phased array implementation and a diffraction grating implementation both rely on a first dispersion of the beam to be demultiplexed and subsequent division of the wavelengths into channels. Local inversion is induced within each channel of the dispersed wavelengths about a channel central wavelength. After the wavelengths are spatially inverted, they are once again provided to a dispersion element or array effectively nullifying the dispersion effects across the channel band to provide output channels having a substantially "flat-tops", while providing good channel separation through global dispersion of all the wavelengths.

Title: Estimating downlink interference in a cellular communications system
Inventor: ISAKSSON KATARINA
IPC: H04W16/18
Filed: 1997-12-16
Abstract: A method is disclosed whereby a cellular network's BA lists are modified so that the mobile terminals (12) in the network (10) can measure downlink interference on predetermined BCCH frequencies. These measurements can be made in all cells where the mobile terminals (12) are located and then reported back to the base station (20). The base station (20) maps the reported measurements to corresponding cells, and uses the mapping to produce a cell-to-cell interdependency matrix. For the preferred embodiment, the matrix describes the difference in path loss between cells. This path loss information can be used to derive downlink C/I or C/A ratios between cells (or combinations of those ratios) and thus an estimate of the downlink reference in the frequencies assigned to the same cells. Consequently, the downlink interference in the network can be taken into account when new frequencies are to be selected for each cell, which can be used to increase the overall quality of the network (in terms of the C/I).
