Patent CA-2304231-A1 (CA)
Title: Displaced aperture beamsplitter for laser transmitter/receiver opto mechanical system
Inventor: PATEL ASHOK B
IPC: G02B27/14
Filed: 1999-08-03
Abstract: A single aperture opto-mechanical system for transmitting two small-aperture laser beams (10, 11) and single received laser beam (12). An in-coming beam (12) is received along a path that is essentially parallel with the path of transmitted beams (10, 11). The small-aperture transmitted beams (10, 11) each pass through a hole (28, 29) in a metal mirror beamsplitter (5) that is positioned to reflect the received light energy (12) at a 90~ angle through a narrow band-pass filter (6) and focused by an aspheric glass lens (7) that directs the received beam energy (12) onto a receiver detector (8). The out-going beams (10, 11) are transmitted through the top and bottom of portions of the afocal beam expanders (18) optical aperture which is specifically achromatized for the two displaced transmitted beams (10, 11) at the two wavelengths such that they exit the beam expander (18) off axis from the optical center line and maintain parallel alignment to within a few micro-radians. The objective lens (1) is movable in a plane orthogonal to the optical axis of the beam expander (18) for steering the two transmitted beams (10, 11) and the receiver beam path (12).

Patent CA-2307236-A1 (CA)
Title: Compositions and methods for reducing the quantity but not the concentration of active ingredients delivered by a dentifrice
Inventor: FISCHER DAN E
IPC: A61Q11/00
Filed: 1998-11-05
Abstract: Toothpaste and other dentifrices formulated to include a volume increasing agent (density reducing agent) in order to significantly increase the volume of the toothpaste at the time it is dispensed onto a toothbrush. The inventive dental compositions preferably include a substantial quantity of entrained air or other gas in order to reduce the density, and hence the weight, of toothpaste actually placed within a person's mouth. The result is a reduction in the amount of active ingredients introduced into a person's mouth that might be ingested. The entrained air or other gas can also increase the availability of the active ingredient since the foamed composition increases the dispersibility of the active ingredients within saliva. The net effect is that a person decreases the actual amount of toothpaste without decreasing the volume, or visual amount, of toothpaste dispensed on the toothbrush. The density-reduction effect can be augmented using a low density filler in addition to, or instead of, entrained gas. The inventive dentifrices might be pre-foamed with a storage container or formulated to foam in situ when dispensed from the storage container.

Title: Method and apparatus for characterization of optical systems
Inventor: HANSEN MATTHEW E
IPC: G03F7/207
Filed: 2000-06-08
Abstract: Characterization of an optical system (18) is quickly and easily obtained in a single acquisition step by obtaining image data within a volume of image space (20). A reticle (16) and image plane (22) are positioned obliquely with respect to each other such that a reticle having a plurality of feature sets (116a-e) thereon, including periodic patterns or gratings (216a-e), is imaged in a volume of space, including the depth of focus. Metrology tools are used to analyze the detected or recorded image in the volume of space through the depth of focus in a single step or exposure to determine the imaging characteristics of an optical system. Focus, field curvature, astigmatism, spherical, coma, and/or focal plane deviations may be determined. The present invention is particularly applicable to semiconductor manufacturing and photolithographic techniques used therein, and is able to quickly characterize an optical system in a single exposure with dramatically increased data quality and continuous coverage of the full parameter space.
